Azure Analysis Services Connection Details

Introduction

Connector Version

This documentation is based on version 22.0.8676 of the connector.

Get Started

Azure Analysis Services Version Support

The connector wraps the complexity of connecting to Azure Analysis Services in a standard driver: execute SQL-92 queries or pass through MDX queries from relational tools.

Establish a Connection

Connect to Azure Analysis Services

To connect, set the URL property to a valid Azure Analysis Services server, for instance, asazure://southcentralus.asazure.windows.net/server, in addition to authenticating.

Optionally, set Database to distinguish which Azure database on the server to connect to.

Authenticate to Azure Analysis Services

Azure AD

Azure AD is a connection type that leverages OAuth to authenticate. OAuth requires the authenticating user to interact with Azure Analysis Services using an internet browser. The connector facilitates this in several ways as described below. Set your AuthScheme to AzureAD. All AzureAD flows assume that you have done so.

Desktop Applications

provides an embedded OAuth application that simplifies OAuth desktop Authentication. Alternatively, you can create a custom OAuth application. See Creating a Custom AzureAD App for information about creating custom applications and reasons for doing so.

For authentication, the only difference between the two methods is that you must set two additional connection properties when using custom OAuth applications.

After setting the following connection properties, you are ready to connect:

  • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
  • OAuthClientId: (custom applications only) Set this to the client ID in your application settings.
  • OAuthClientSecret: (custom applications only) Set this to the client secret in your application settings.
  • CallbackURL: Set this to the Redirect URL in your application settings.

When you connect the connector opens the OAuth endpoint in your default browser. Log in and grant permissions to the application. The connector then completes the OAuth process:

  1. Extracts the access token from the callback URL and authenticates requests.
  2. Obtains a new access token when the old one expires.
  3. Saves OAuth values in OAuthSettingsLocation that persist across connections.
Azure Service Principal

Azure Service Principal is a connection type that goes through OAuth. Set your AuthScheme to AzureServicePrincipal. The authentication as an Azure Service Principal is handled via the OAuth Client Credentials flow, and it does not involve direct user authentication. Instead, credentials are created for just the app itself. All tasks taken by the app are done without a default user context, but based on the assigned roles. The application access to the resources is controlled through the assigned roles' permissions.

Note

You must create a custom application prior to assigning a role. See Creating a Custom AzureAD App for more information.

When authenticating using an Azure Service Principal, you must register an application with an Azure AD tenant. Follow the steps below to create a new service principal that can be used with the role-based access control.

Assign a role to the application

To access resources in your subscription, you must assign a role to the application.

  1. Open the Subscriptions page by searching and selecting the Subscriptions service from the search bar.
  2. Select the particular subscription to assign the application to.
  3. Open the Access control (IAM) and select Add > Add role assignment to open the Add role assignment page.
  4. Select Owner as the role to assign to your created Azure AD app.
Complete the Authentication

You are ready to connect after setting one of the below connection properties groups, depending on the configured app authentication (client secret or certificate).

In both methods

Before choosing client secret or certicate authentication, follow these steps then continue to the relevant section below:

  1. AuthScheme: Set this to the AzureServicePrincipal in your app settings.
  2. InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
  3. AzureTenant: Set this to the tenant you wish to connect to.
  4. OAuthClientId: Set this to the client ID in your app settings.

Authenticating using a Client Secret

Continue with the following:

  1. OAuthClientId: Set this to the client ID in your app settings.
  2. OAuthClientSecret: Set this to the client secret in your app settings.

Authenticating using a Certificate

Continue with the following:

  1. OAuthJWTCert: Set this to the JWT Certificate store.
  2. OAuthJWTCertType: Set this to the type of the certificate store specified by OAuthJWTCert.
Azure Password

To connect using your Azure credentials directly, specify the following connection properties:

  • AuthScheme: Set this to AzurePassword.
  • User: Set this to your user account you use to connect to Azure.
  • Password: Set this to the password you use to connect to Azure.
  • AzureTenant: Set this to the Directory (tenant) ID, found on the Overview page of the OAuth app used to authenticate to Azure Analysis Services on Azure.
MSI

If you are running Azure Analysis Services on an Azure VM, you can leverage Managed Service Identity (MSI) credentials to connect:

  • AuthScheme: Set this to AzureMSI.

The MSI credentials are automatically obtained for authentication.

Create a Custom AzureAD App

There are two types of custom AzureAD applications: AzureAD and AzureAD with an Azure Service Principal. Both are OAuth-based.

When to Create a Custom Application

embeds OAuth Application Credentials with branding that can be used when connecting via either a Desktop Application or from a Headless Machine.

You may choose to use your own AzureAD Application Credentials when you want to

  • control branding of the Authentication Dialog
  • control the redirect URI that the application redirects the user to after the user authenticates
  • customize the permissions that you are requesting from the user

Custom AzureAD Applications

You can use a custom AzureAD application to authenticate a service account or a user account. You can always create a custom AzureAD application, but note that desktop and headless connections support embedded OAuth, which simplifies the process of authentication. See "Establishing a Connection" for information about using the embedded OAuth application.

Create a Custom AzureAD App

Follow the steps below to obtain the AzureAD values for your application, the OAuthClientId and OAuthClientSecret.

  1. Log in to https://portal.azure.com.

  2. In the left-hand navigation pane, select Azure Active Directory, then applicationRegistrations, and click New registration.

  3. Enter an application name and select the desired tenant setup.

    When creating a custom AzureAD application in Azure Active Directory, you can define whether the application is single- or multi-tenant. If you select the default option, "Accounts in this organizational directory only", you must set the AzureTenant connection property to the ID of the Azure AD Tenant when establishing a connection with the Azure Analysis Services connector. Otherwise, the authentication attempt fails with an error. If your application is for private use only, "Accounts in this organization directory only" should be sufficient. Otherwise, if you want to distribute your application, choose one of the multi-tenant options.

  4. Set the redirect URL to http://localhost:33333, the connector's default. Or, specify a different port and set CallbackURL to the exact reply URL you defined.

  5. Click Register to register the new application. This opens an application management screen. Note the value in Application (client) ID as the OAuthClientId and the Directory (tenant) ID as the AzureTenant.

  6. Navigate to the "Certificates & Secrets" and define the application authentication type. There are two types of authentication available: client secret or certificate. The recommended authentication method is using a certificate.

    • Option 1: Upload a certificate: In "Certificates & Secrets", select Upload certificate and the certificate to upload from your local machine.
    • Option 2: Create a new application secret: In "Certificates & Secrets", select New Client Secret for the application and specify its duration. After saving the client secret, the key value is displayed. Copy this value as it is displayed only once. You will need it as the OAuthClientSecret.
  7. Select API Permissions > Add > Delegated permissions.

  8. Save your changes.

  9. If you have selected to use permissions that require admin consent, you can grant them from the current tenant on the API Permissions page.

Use Azure Service Principal Authentication

The authentication as an Azure Service Principal is handled via the OAuth Client Credentials flow, and it does not involve direct user authentication. Instead, credentials are created for just the app itself. All tasks taken by the app are done without a default user context, but based on the assigned roles. The application access to the resources is controlled through the assigned roles' permissions.

Create an AzureAD App and an Azure Service Principal

When authenticating using an Azure Service Principal, you must register an application with an Azure AD tenant.

Assign a role to the application

To access resources in your subscription, you must assign a role to the application.

  1. Open the Subscriptions page by searching and selecting the Subscriptions service from the search bar.
  2. Select the particular subscription to assign the application to.
  3. Open the Access control (IAM) and select Add > Add role assignment to open the Add role assignment page.
  4. Select Owner as the role to assign to your created Azure AD app.

Complete the Authentication

You are ready to connect after setting one of the below connection properties groups, depending on the configured app authentication (client secret or certificate).

In both methods

Before choosing client secret or certicate authentication, follow these steps then continue to the relevant section below:

  1. AuthScheme: Set this to the AzureServicePrincipal in your app settings.
  2. InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
  3. AzureTenant: Set this to the tenant you wish to connect to.
  4. OAuthClientId: Set this to the client ID in your app settings.

Authenticating using a Client Secret

Continue with the following:

  1. OAuthClientId: Set this to the client ID in your app settings.
  2. OAuthClientSecret: Set this to the client secret in your app settings.

Authenticating using a Certificate

Continue with the following:

  1. OAuthJWTCert: Set this to the JWT Certificate store.
  2. OAuthJWTCertType: Set this to the type of the certificate store specified by OAuthJWTCert.

Retrieve Analysis Services Data

Azure Analysis Services is an OLAP database that exposes data as cubes, which you query with MDX (multidimensional expressions). The connector models these cubes in relational views that you can query with SQL-92. The following mapping is for the layout of the model:

  • Catalog - Displayed in the connector as a Catalog.
  • Cube - Displayed in the connector as a Schema.
  • Measure - Available in the connector under the special Measures view.
  • Dimension - Each dimension is exposed as a view.
  • Level - Each individual level of a hierarchy is exposed as a column on the appropriate dimension view.

Join Measures and Dimensions

In order to retrieve measures per specific level value, issue a join between the Measure view and any Dimension or set of dimensions. For example, issuing the following will retrieve the number of customers in each city:

SELECT m.[Customer Count], c.[City]
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c
INNER JOIN [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Measures AS m

Note that there is no ON condition necessary. That is because tables are already related appropriately in Azure Analysis Services. If you are using a tool that requires ON conditions, set IncludeJoinColumns to true. This will append a number of foreign key columns to each view which will relate them to one another another. These columns will not return data on their own, but may be picked up on automatically with tools to construct the ON conditions for joins where needed.

Aggregate Data

Data stored in Azure Analysis Services is already aggregated. In many cases, attempting to retrieve an aggregate may be syntactically equivalent to not specifying anything. For example, the following query will return the exact same data as the previous:

SELECT SUM(m.[Customer Count]), c.[City]
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c
INNER JOIN [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Measures AS m
GROUP BY c.[City]

The exception to this rule is when an aggregation of filtered results is requested. In such cases, a calculation will be requested from Azure Analysis Services. For example, to calculate the sum and average of customers in France and Germany:

SELECT SUM(m.[Customer Count]), AVG(m.[Customer Count]), c.[Country]
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c
INNER JOIN [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Measures AS m
WHERE c.[Country] IN ('France', 'Germany')
GROUP BY c.[Country]

Select Multiple Hierarchies

In Azure Analysis Services, individual dimensions are made up of hierarchies which may have one or more levels. For instance, the AdventureWorks Customers table has City, Country and Gender. City and Country are part of the same hierarchy while Gender is its own hierarchy.

When selecting multiple hierarchies, the method to support this is to cross join the values in MDX. While not obvious from a relational table model of the data as the connector presents, this can cause for very expensive queries to be executed. For example, executing the following:

SELECT c.[Country], m.[Customer Count]
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c
INNER JOIN [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Measures AS m

Will result in 6 rows. However, selecting Gender as well:

SELECT c.[Country], c.[Gender], m.[Customer Count]
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c
INNER JOIN [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Measures AS m

Will now result in 12 rows. It is because Gender and Country are on different hierarchies, thus a crossjoin is required in order to return both together. Each additional hierarchy added to the SELECT will multiply the total results by the number of available values in that hierarchy. Thus to get a count of how many rows to expect, one can execute the following:

SELECT (Count(c.[Country])*Count(c.[Gender])) AS totalrows
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c 

Response Row Limit

Due to how selecting multiple hierarchies will multiply the total number of result rows, it is possible to balloon the number of response rows very quickly, which will result in timeouts. In order to try and give some visibility into what queries will be very expensive, the ResponseRowLimit connection property has been added as a mechanism to try and guide users into better practices. When set, it will calculate how many rows to expect before any query is executed. If the number of predicted rows exceeds the limit, an error will be thrown indicating how many rows to expect back with the query.

It is recommended to select only the columns required or to apply a WHERE criteria. Both can significantly reduce the number of response rows, which will have a huge impact on performance. If you are already familiar with the connector and what queries may be expensive, ResponseRowLimit may be disabled by setting it to 0.

Fine-Tuning Data Access

Fine Tuning Data Access

Set the following other properties may also be useful in certain situations:

  • UseMDX: Indicates if MDX queries are being submitted. By default this is false, which will cause the driver to accept only SQL-92 compliant queries. Setting this property to true will cause all queries to be passed through directly to Azure Analysis Services.

  • ExtraProperties: Additional properties to submit along with an MDX query. Only meaningful if UseMDX is true.

  • IncludeJoinColumns: Boolean indicating if extra columns used to make ON conditions with joins should be added.

    These do not come back with any values - they are added purely to enable tools that require them in order to automatically set up relationships between tables when creating joins.

  • ResponseRowLimit: Sets a calculated limit on the number of rows to allow the user to select before returning an error.

    Because queries are being translated to MDX, selecting only a few columns may exponentially multiply the number of expected results.

    For this reason, ResponseRowLimit is available to try and give some guidance on what types of queries are likely to result in a Timeout. May be disabled by setting to 0.

Important Notes

Configuration Files and Their Paths

  • All references to adding configuration files and their paths refer to files and locations on the Harmony Agent where the connector is installed. These paths are to be adjusted as appropriate depending on the agent and the operating system. If multiple agents are used in an agent group, identical files will be required on each agent.

Advanced Features

This section details a selection of advanced features of the Azure Analysis Services connector.

User Defined Views

The connector allows you to define virtual tables, called user defined views, whose contents are decided by a pre-configured query. These views are useful when you cannot directly control queries being issued to the drivers. See User Defined Views for an overview of creating and configuring custom views.

SSL Configuration

Use SSL Configuration to adjust how connector handles TLS/SSL certificate negotiations. You can choose from various certificate formats; see the SSLServerCert property under "Connection String Options" for more information.

Proxy

To configure the connector using Private Agent proxy settings, select the Use Proxy Settings checkbox on the connection configuration screen.

Query Processing

The connector offloads as much of the SELECT statement processing as possible to Azure Analysis Services and then processes the rest of the query in memory (client-side).

See Query Processing for more information.

User Defined Views

The Azure Analysis Services connector allows you to define a virtual table whose contents are decided by a pre-configured query. These are called User Defined Views, which are useful in situations where you cannot directly control the query being issued to the driver, e.g. when using the driver from Jitterbit. The User Defined Views can be used to define predicates that are always applied. If you specify additional predicates in the query to the view, they are combined with the query already defined as part of the view.

There are two ways to create user defined views:

  • Create a JSON-formatted configuration file defining the views you want.
  • DDL statements.

Define Views Using a Configuration File

User Defined Views are defined in a JSON-formatted configuration file called UserDefinedViews.json. The connector automatically detects the views specified in this file.

You can also have multiple view definitions and control them using the UserDefinedViews connection property. When you use this property, only the specified views are seen by the connector.

This User Defined View configuration file is formatted as follows:

  • Each root element defines the name of a view.
  • Each root element contains a child element, called query, which contains the custom SQL query for the view.

For example:

{
    "MyView": {
        "query": "SELECT * FROM [adventureworks].[Model].Customer WHERE MyColumn = 'value'"
    },
    "MyView2": {
        "query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
    }
}

Use the UserDefinedViews connection property to specify the location of your JSON configuration file. For example:

"UserDefinedViews", "C:\Users\yourusername\Desktop\tmp\UserDefinedViews.json"

Define Views Using DDL Statements

The connector is also capable of creating and altering the schema via DDL Statements such as CREATE LOCAL VIEW, ALTER LOCAL VIEW, and DROP LOCAL VIEW.

Create a View

To create a new view using DDL statements, provide the view name and query as follows:

CREATE LOCAL VIEW [MyViewName] AS SELECT * FROM Customers LIMIT 20;

If no JSON file exists, the above code creates one. The view is then created in the JSON configuration file and is now discoverable. The JSON file location is specified by the UserDefinedViews connection property.

Alter a View

To alter an existing view, provide the name of an existing view alongside the new query you would like to use instead:

ALTER LOCAL VIEW [MyViewName] AS SELECT * FROM Customers WHERE TimeModified > '3/1/2020';

The view is then updated in the JSON configuration file.

Drop a View

To drop an existing view, provide the name of an existing schema alongside the new query you would like to use instead.

DROP LOCAL VIEW [MyViewName]

This removes the view from the JSON configuration file. It can no longer be queried.

Schema for User Defined Views

User Defined Views are exposed in the UserViews schema by default. This is done to avoid the view's name clashing with an actual entity in the data model. You can change the name of the schema used for UserViews by setting the UserViewsSchemaName property.

Work with User Defined Views

For example, a SQL statement with a User Defined View called UserViews.RCustomers only lists customers in Raleigh:

SELECT * FROM Customers WHERE City = 'Raleigh';

An example of a query to the driver:

SELECT * FROM UserViews.RCustomers WHERE Status = 'Active';

Resulting in the effective query to the source:

SELECT * FROM Customers WHERE City = 'Raleigh' AND Status = 'Active';

That is a very simple example of a query to a User Defined View that is effectively a combination of the view query and the view definition. It is possible to compose these queries in much more complex patterns. All SQL operations are allowed in both queries and are combined when appropriate.

SSL Configuration

Customize the SSL Configuration

By default, the connector attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store.

To specify another certificate, see the SSLServerCert property for the available formats to do so.

Client SSL Certificates

The Azure Analysis Services connector also supports setting client certificates. Set the following to connect using a client certificate.

  • SSLClientCert: The name of the certificate store for the client certificate.
  • SSLClientCertType: The type of key store containing the TLS/SSL client certificate.
  • SSLClientCertPassword: The password for the TLS/SSL client certificate.
  • SSLClientCertSubject: The subject of the TLS/SSL client certificate.

Data Model

Azure Analysis Services is an OLAP database that exposes data as cubes, which you query with MDX (multidimensional expressions). The connector models these cubes in relational views that you can query with SQL-92. The following mapping is for the layout of the model:

  • Catalog - Displayed in the connector as a Catalog.
  • Cube - Displayed in the connector as a Schema.
  • Measure - Available in the connector under the special Measures view.
  • Dimension - Each dimension is exposed as a view.
  • Level - Each individual level of a hierarchy is exposed as a column on the appropriate dimension view.

Measure Attributes

By default, all measure attributes are listed in a 'Measures' view. However, you can set SplitMeasures to 'true' to split the measures view; the result is each measure attribute is included in its respective view based on the Measure Group value. Further classification based on 'Measure Directories' is not included.

Joining Measures and Dimensions

In order to retrieve measures per specific level value, issue a join between the Measure view and any Dimension or set of dimensions. For example, issuing the following will retrieve the number of customers in each city:

SELECT m.[Customer Count], c.[City]
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c
INNER JOIN [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Measures AS m

Note that there is no ON condition necessary. That is because tables are already related appropriately in Azure Analysis Services. If you are using a tool that requires ON conditions, set IncludeJoinColumns to true. This will append a number of foreign key columns to each view which will relate them to one another another. These columns will not return data on their own, but may be picked up on automatically with tools to construct the ON conditions for joins where needed.

Aggregating Data

Data stored in Azure Analysis Services is already aggregated. In many cases, attempting to retrieve an aggregate may be syntactically equivalent to not specifying anything. For example, the following query will return the exact same data as the previous:

SELECT SUM(m.[Customer Count]), c.[City]
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c
INNER JOIN [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Measures AS m
GROUP BY c.[City]

The exception to this rule is when an aggregation of filtered results is requested. In such cases, a calculation will be requested from Azure Analysis Services. For example, to calculate the sum and average of customers in France and Germany:

SELECT SUM(m.[Customer Count]), AVG(m.[Customer Count]), c.[Country]
FROM [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Customer AS c
INNER JOIN [AdventureWorksDW2012Multidimensional-SE].[Adventure Works].Measures AS m
WHERE c.[Country] IN ('France', 'Germany')
GROUP BY c.[Country]

Possible Values

AzureAD, AzureMSI, AzurePassword, AzureServicePrincipal

Data Type

string

Default Value

AzureAD

Remarks
  • AzureAD: Set this to perform Azure Active Directory OAuth authentication.
  • AzureMSI: Set this to automatically obtain Managed Service Identity credentials when running on an Azure VM.
  • AzurePassword: Set this to submit User and Password to Azure. Under the hood, an OAuth process will still take place, but user/password credentials will be submitted which will avoid a browser window that will request authorization.
  • AzureServicePrincipal: Set this to authenticate as an Azure Service Principal.

URL

The URL used to connect to the Azure Analysis Services.

Data Type

string

Default Value

""

Remarks

The HTTP or HTTPS URL used to connect to the Azure Analysis Services in the format asazure://\[region\].asazure.windows.net/\[server\]. You can obtain the server name in Azure portal -> Overview -> Server name.

User

The Azure Analysis Services user account used to authenticate.

Data Type

string

Default Value

""

Remarks

Together with Password, this field is used to authenticate against the Azure Analysis Services server.

Password

The password used to authenticate the user.

Data Type

string

Default Value

""

Remarks

The User and Password are together used to authenticate with the server.

Azure Authentication

This section provides a complete list of Azure authentication properties you can configure.

Property Description
AzureTenant The Microsoft Online tenant being used to access data. If not specified, your default tenant is used.
AzureEnvironment The Azure Environment to use when establishing a connection.

AzureTenant

The Microsoft Online tenant being used to access data. If not specified, your default tenant is used.

Data Type

string

Default Value

""

Remarks

The Microsoft Online tenant being used to access data. For instance, contoso.onmicrosoft.com. Alternatively, specify the tenant Id. This value is the directory ID in the Azure Portal > Azure Active Directory > Properties.

Typically it is not necessary to specify the Tenant. This can be automatically determined by Microsoft when using the OAuthGrantType set to CODE (default). However, it may fail in the case that the user belongs to multiple tenants. For instance, if an Admin of domain A invites a user of domain B to be a guest user. The user will now belong to both tenants. It is a good practice to specify the Tenant, although in general things should normally work without having to specify it.

The AzureTenant is required when setting OAuthGrantType to CLIENT. When using client credentials, there is no user context. The credentials are taken from the context of the app itself. While Microsoft still allows client credentials to be obtained without specifying which Tenant, it has a much lower probability of picking the specific tenant you want to work with. For this reason, we require AzureTenant to be explicitly stated for all client credentials connections to ensure you get credentials that are applicable for the domain you intend to connect to.

AzureEnvironment

The Azure Environment to use when establishing a connection.

Possible Values

GLOBAL, CHINA, USGOVT, USGOVTDOD

Data Type

string

Default Value

GLOBAL

Remarks

In most cases, leaving the environment set to global will work. However, if your Azure Account has been added to a different environment, the AzureEnvironment may be used to specify which environment. The available values are GLOBAL, CHINA, USGOVT, USGOVTDOD.

OAuth

This section provides a complete list of OAuth properties you can configure.

CallbackURL The OAuth callback URL to return to when authenticating. This value must match the callback URL you specify in your app settings.
OAuthVerifier The verifier code returned from the OAuth authorization URL.
OAuthRefreshToken The OAuth refresh token for the corresponding OAuth access token.
OAuthExpiresIn The lifetime in seconds of the OAuth AccessToken.
OAuthTokenTimestamp The Unix epoch timestamp in milliseconds when the current Access Token was created.

InitiateOAuth

Set this property to initiate the process to obtain or refresh the OAuth access token when you connect.

Possible Values

OFF, GETANDREFRESH, REFRESH

Data Type

string

Default Value

OFF

Remarks

The following options are available:

  1. OFF: Indicates that the OAuth flow will be handled entirely by the user. An OAuthAccessToken will be required to authenticate.
  2. GETANDREFRESH: Indicates that the entire OAuth Flow will be handled by the connector. If no token currently exists, it will be obtained by prompting the user via the browser. If a token exists, it will be refreshed when applicable.
  3. REFRESH: Indicates that the connector will only handle refreshing the OAuthAccessToken. The user will never be prompted by the connector to authenticate via the browser. The user must handle obtaining the OAuthAccessToken and OAuthRefreshToken initially.

OAuthClientId

The client ID assigned when you register your application with an OAuth authorization server.

Data Type

string

Default Value

""

Remarks

As part of registering an OAuth application, you will receive the OAuthClientId value, sometimes also called a consumer key, and a client secret, the OAuthClientSecret.

OAuthClientSecret

The client secret assigned when you register your application with an OAuth authorization server.

Data Type

string

Default Value

""

Remarks

As part of registering an OAuth application, you will receive the OAuthClientId, also called a consumer key. You will also receive a client secret, also called a consumer secret. Set the client secret in the OAuthClientSecret property.

OAuthAccessToken

The access token for connecting using OAuth.

Data Type

string

Default Value

""

Remarks

The OAuthAccessToken property is used to connect using OAuth. The OAuthAccessToken is retrieved from the OAuth server as part of the authentication process. It has a server-dependent timeout and can be reused between requests.

The access token is used in place of your user name and password. The access token protects your credentials by keeping them on the server.

OAuthGrantType

The grant type for the OAuth flow.

Possible Values

CODE, CLIENT

Data Type

string

Default Value

CODE

Remarks

The following options are available: CODE,CLIENT

OAuthSettingsLocation

The location of the settings file where OAuth values are saved when InitiateOAuth is set to GETANDREFRESH or REFRESH. Alternatively, this can be held in memory by specifying a value starting with memory://.

Data Type

string

Default Value

%APPDATA%\AAS Data Provider\OAuthSettings.txt

Remarks

When InitiateOAuth is set to GETANDREFRESH or REFRESH, the connector saves OAuth values to avoid requiring the user to manually enter OAuth connection properties and allowing the credentials to be shared across connections or processes.

Alternatively to specifying a file path, memory storage can be used instead. Memory locations are specified by using a value starting with 'memory://' followed by a unique identifier for that set of credentials (ex: memory://user1). The identifier can be anything you choose but should be unique to the user. Unlike with the file based storage, you must manually store the credentials when closing the connection with memory storage to be able to set them in the connection when the process is started again. The OAuth property values can be retrieved with a query to the sys_connection_props system table. If there are multiple connections using the same credentials, the properties should be read from the last connection to be closed.

If left unspecified, the default location is "%APPDATA%\AAS Data Provider\OAuthSettings.txt" with %APPDATA% being set to the user's configuration directory:

Platform %APPDATA%
Windows The value of the APPDATA environment variable
Mac ~/Library/Application Support
Linux ~/.config

CallbackURL

The OAuth callback URL to return to when authenticating. This value must match the callback URL you specify in your app settings.

Data Type

string

Default Value

""

Remarks

During the authentication process, the OAuth authorization server redirects the user to this URL. This value must match the callback URL you specify in your app settings.

OAuthVerifier

The verifier code returned from the OAuth authorization URL.

Data Type

string

Default Value

""

Remarks

The verifier code returned from the OAuth authorization URL. This can be used on systems where a browser cannot be launched such as headless systems.

Authentication on Headless Machines

See to obtain the OAuthVerifier value.

Set OAuthSettingsLocation along with OAuthVerifier. When you connect, the connector exchanges the OAuthVerifier for the OAuth authentication tokens and saves them, encrypted, to the specified file. Set InitiateOAuth to GETANDREFRESH to automate the exchange.

Once the OAuth settings file has been generated, you can remove OAuthVerifier from the connection properties and connect with OAuthSettingsLocation set.

To automatically refresh the OAuth token values, set OAuthSettingsLocation and additionally set InitiateOAuth to REFRESH.

OAuthRefreshToken

The OAuth refresh token for the corresponding OAuth access token.

Data Type

string

Default Value

""

Remarks

The OAuthRefreshToken property is used to refresh the OAuthAccessToken when using OAuth authentication.

OAuthExpiresIn

The lifetime in seconds of the OAuth AccessToken.

SSLClientCert is used in conjunction with the SSLClientCertSubject field in order to specify client certificates. If SSLClientCert has a value, and SSLClientCertSubject is set, a search for a certificate is initiated. See SSLClientCertSubject for more information.

Designations of certificate stores are platform-dependent.

The following are designations of the most common User and Machine certificate stores in Windows:

Property Description
MY A certificate store holding personal certificates with their associated private keys.
CA Certifying authority certificates.
ROOT Root certificates.
SPC Software publisher certificates.

In Java, the certificate store normally is a file containing certificates and optional private keys.

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (for example, PKCS12 certificate store).

SSLClientCertType

The type of key store containing the TLS/SSL client certificate.

Possible Values

USER, MACHINE, PFXFILE, PFXBLOB, JKSFILE, JKSBLOB, PEMKEY_FILE, PEMKEY_BLOB, PUBLIC_KEY_FILE, PUBLIC_KEY_BLOB, SSHPUBLIC_KEY_FILE, SSHPUBLIC_KEY_BLOB, P7BFILE, PPKFILE, XMLFILE, XMLBLOB

Data Type

string

Default Value

USER

Remarks

This property can take one of the following values:

Property Description
USER - default For Windows, this specifies that the certificate store is a certificate store owned by the current user. Note that this store type is not available in Java.
MACHINE For Windows, this specifies that the certificate store is a machine store. Note that this store type is not available in Java.
PFXFILE The certificate store is the name of a PFX (PKCS12) file containing certificates.
PFXBLOB The certificate store is a string (base-64-encoded) representing a certificate store in PFX (PKCS12) format.
JKSFILE The certificate store is the name of a Java key store (JKS) file containing certificates. Note that this store type is only available in Java.
JKSBLOB The certificate store is a string (base-64-encoded) representing a certificate store in JKS format. Note that this store type is only available in Java.
PEMKEY_FILE The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
PEMKEY_BLOB The certificate store is a string (base64-encoded) that contains a private key and an optional certificate.
PUBLIC_KEY_FILE The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate.
PUBLIC_KEY_BLOB The certificate store is a string (base-64-encoded) that contains a PEM- or DER-encoded public key certificate.
SSHPUBLIC_KEY_FILE The certificate store is the name of a file that contains an SSH-style public key.
SSHPUBLIC_KEY_BLOB The certificate store is a string (base-64-encoded) that contains an SSH-style public key.
P7BFILE The certificate store is the name of a PKCS7 file containing certificates.
PPKFILE The certificate store is the name of a file that contains a PuTTY Private Key (PPK).
XMLFILE The certificate store is the name of a file that contains a certificate in XML format.
XMLBLOB The certificate store is a string that contains a certificate in XML format.

SSLClientCertPassword

The password for the TLS/SSL client certificate.

Data Type

string

Default Value

""

Remarks

If the certificate store is of a type that requires a password, this property is used to specify that password to open the certificate store.

SSLClientCertSubject

The subject of the TLS/SSL client certificate.

Data Type

string

Default Value

*

Remarks

When loading a certificate the subject is used to locate the certificate in the store.

If an exact match is not found, the store is searched for subjects containing the value of the property. If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks the first certificate in the certificate store.

The certificate subject is a comma separated list of distinguished name fields and values. For example, "CN=www.server.com, OU=test, C=US, E=support@company.com". The common fields and their meanings are shown below.

Field Meaning
CN Common Name. This is commonly a host name like www.server.com.
O Organization
OU Organizational Unit
L Locality
S State
C Country
E Email Address

If a field value contains a comma, it must be quoted.

SSLServerCert

The certificate to be accepted from the server when connecting using TLS/SSL.

Data Type

string

Default Value

""

Remarks

If using a TLS/SSL connection, this property can be used to specify the TLS/SSL certificate to be accepted from the server. Any other certificate that is not trusted by the machine is rejected.

This property can take the following forms:

Description Example
A full PEM Certificate (example shortened for brevity) -----BEGIN CERTIFICATE----- MIIChTCCAe4CAQAwDQYJKoZIhv......Qw== -----END CERTIFICATE-----
A path to a local file containing the certificate C:\cert.cer
The public key (example shortened for brevity) -----BEGIN RSA PUBLIC KEY----- MIGfMA0GCSq......AQAB -----END RSA PUBLIC KEY-----
The MD5 Thumbprint (hex values can also be either space or colon separated) ecadbdda5a1529c58a1e9e09828d70e4
The SHA1 Thumbprint (hex values can also be either space or colon separated) 34a929226ae0819f2ec14b4a3d904f801cbb150d

If not specified, any certificate trusted by the machine is accepted.

Certificates are validated as trusted by the machine based on the System's trust store. The trust store used is the 'javax.net.ssl.trustStore' value specified for the system. If no value is specified for this property, Java's default trust store is used (for example, JAVA_HOME\lib\security\cacerts).

Use '*' to signify to accept all certificates. Note that this is not recommended due to security concerns.

Schema

This section provides a complete list of schema properties you can configure.

Property Description
Location A path to the directory that contains the schema files defining tables, views, and stored procedures.
BrowsableSchemas This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA, SchemaB, SchemaC.
Tables This property restricts the tables reported to a subset of the available tables. For example, Tables=TableA, TableB, TableC.
Views Restricts the views reported to a subset of the available tables. For example, Views=ViewA, ViewB, ViewC.
Catalog The Analysis Services catalog to use. This may also be known as a Database from within Analysis Services.
IncludeJoinColumns Set this to true to include extra join columns on each table.

Location

A path to the directory that contains the schema files defining tables, views, and stored procedures.

Data Type

string

Default Value

%APPDATA%\AAS Data Provider\Schema

Remarks

The path to a directory which contains the schema files for the connector (.rsd files for tables and views, .rsb files for stored procedures). The folder location can be a relative path from the location of the executable. The Location property is only needed if you want to customize definitions (for example, change a column name, ignore a column, and so on) or extend the data model with new tables, views, or stored procedures.

If left unspecified, the default location is "%APPDATA%\AAS Data Provider\Schema" with %APPDATA% being set to the user's configuration directory:

Platform %APPDATA%
Windows The value of the APPDATA environment variable
Mac ~/Library/Application Support
Linux ~/.config

BrowsableSchemas

This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC.

Data Type

string

Default Value

""

Remarks

Listing the schemas from databases can be expensive. Providing a list of schemas in the connection string improves the performance.

Tables

This property restricts the tables reported to a subset of the available tables. For example, Tables=TableA,TableB,TableC.

Data Type

string

Default Value

""

Remarks

Listing the tables from some databases can be expensive. Providing a list of tables in the connection string improves the performance of the connector.

This property can also be used as an alternative to automatically listing views if you already know which ones you want to work with and there would otherwise be too many to work with.

Specify the tables you want in a comma-separated list. Each table should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Tables=TableA,[TableB/WithSlash],WithCatalog.WithSchema.`TableC With Space`.

Note that when connecting to a data source with multiple schemas or catalogs, you will need to provide the fully qualified name of the table in this property, as in the last example here, to avoid ambiguity between tables that exist in multiple catalogs or schemas.

Views

Restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC.

Data Type

string

Default Value

""

Remarks

Listing the views from some databases can be expensive. Providing a list of views in the connection string improves the performance of the connector.

This property can also be used as an alternative to automatically listing views if you already know which ones you want to work with and there would otherwise be too many to work with.

Specify the views you want in a comma-separated list. Each view should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Views=ViewA,[ViewB/WithSlash],WithCatalog.WithSchema.`ViewC With Space`.

Note that when connecting to a data source with multiple schemas or catalogs, you will need to provide the fully qualified name of the table in this property, as in the last example here, to avoid ambiguity between tables that exist in multiple catalogs or schemas.

Catalog

The Analysis Services catalog to use. This may also be known as a Database from within Analysis Services.

Data Type

string

Default Value

""

Remarks

This input is optional as catalogs will be displayed by default. However, if if you have UseMDX set to true, this value will ensure the MDX queries are submitted to the correct catalog.

IncludeJoinColumns

Set this to true to include extra join columns on each table.

Data Type

bool

Default Value

false

Remarks

Some tools may require an ON condition (or generate them automatically) based on foreign key references. By setting IncludeJoinColumns to true, every table will include a foreign key reference to the other tables. These columns will not return any data and are not useful for anything other than passing as ON conditions to perform joins upon.

In Azure Analysis Services, the dimensions and measures making up the tables are already related naturally. There is no context on which to join them provided. Therefore, the Azure Analysis Services connector supports joining without specifying an ON condition, so they are optional to specify.

Miscellaneous

This section provides a complete list of miscellaneous properties you can configure.

Property Description
CustomHeaders Other headers as determined by the user (optional).
ExpressionInDescription Set this to true to report expressions as part of the description on measure columns.
ExtraProperties Additional properties to submit on each MDX request to Azure Analysis Services.
MaxRows Limits the number of rows returned rows when no aggregation or group by is used in the query. This helps avoid performance issues at design time.
Other These hidden properties are used only in specific use cases.
ResponseRowLimit The number of response rows to allow before erroring. Set to 0 for now limit.
ShowHiddenEntities Set this to true to include hidden dimensions, measures and levels.
SplitMeasures Set this to true to split Measures table into individual tables.
Timeout The value in seconds until the timeout error is thrown, canceling the operation.
UseMDX Set this to true to pass MDX queries to Azure Analysis Services as-is.
UserDefinedViews A filepath pointing to the JSON configuration file containing your custom views.

CustomHeaders

Other headers as determined by the user (optional).

Data Type

string

Default Value

""

Remarks

This property can be set to a string of headers to be appended to the HTTP request headers created from other properties, like ContentType, From, and so on.

The headers must be of the format "header: value" as described in the HTTP specifications. Header lines should be separated by the carriage return and line feed (CRLF) characters.

Use this property with caution. If this property contains invalid headers, HTTP requests may fail.

This property is useful for fine-tuning the functionality of the connector to integrate with specialized or nonstandard APIs.

ExpressionInDescription

Set this to true to report expressions as part of the description on measure columns.

Data Type

bool

Default Value

false

Remarks

The connector reports the remarks for several types of entities (dimensions, measures, measure groups and heirarchies) as table and column descriptions. By default, the connector will include only the remarks in measure column descriptions.

If this option is enabled, then the measure expression is included in the measure column description, along with the remarks. The descriptions on other types of entities are not affected.

ExtraProperties

Additional properties to submit on each MDX request to Azure Analysis Services.

Data Type

string

Default Value

""

Remarks

When setting UseMDX to true, properties may be specified using this connection property to fill out extra values in the PropertiesList of the XMLA request. Use name=value pairs separated by a semicolon to submit the properties. For example, Catalog=MyCatalog;Cube=MyCube;.

A list of properties may be found by executing SELECT * FROM $System.DISCOVER_PROPERTIES.

MaxRows

Limits the number of rows returned rows when no aggregation or group by is used in the query. This helps avoid performance issues at design time.

Data Type

int

Default Value

-1

Remarks

Limits the number of rows returned rows when no aggregation or group by is used in the query. This helps avoid performance issues at design time.

Other

These hidden properties are used only in specific use cases.

Data Type

string

Default Value

""

Remarks

The properties listed below are available for specific use cases. Normal driver use cases and functionality should not require these properties.

Specify multiple properties in a semicolon-separated list.

Integration and Formatting
Property Description
DefaultColumnSize Sets the default length of string fields when the data source does not provide column length in the metadata. The default value is 2000.
ConvertDateTimeToGMT Determines whether to convert date-time values to GMT, instead of the local time of the machine.
RecordToFile=filename Records the underlying socket data transfer to the specified file.

ResponseRowLimit

The number of response rows to allow before erroring. Set to 0 for now limit.

Data Type

int

Default Value

100000

Remarks

Selecting a lot of columns results in a number of crossjoins occurring under the hood when translated to something that is acceptable for Azure Analysis Services. This is not intuitive if you are not familiar with MDX. It can easily result in very large responses that time out. The ResponseRowLimit is designed to try and alert the user to understand what can be very expensive requests.

ShowHiddenEntities

Set this to true to include hidden dimensions, measures and levels.

Data Type

bool

Default Value

false

Remarks

By default the connector does not report entities that Azure Analysis Services marks as hidden. Enabling this option allows you to query them.

SplitMeasures

Set this to true to split Measures table into individual tables.

Data Type

bool

Default Value

false

Remarks

All measures are currently grouped into a single table 'Measures'. Set this to true to split Measures table into individual tables (if a table only contains measures) and include measures into respective dimensions tables.

Timeout

The value in seconds until the timeout error is thrown, canceling the operation.

Data Type

int

Default Value

60

Remarks

If Timeout = 0, operations do not time out. The operations run until they complete successfully or until they encounter an error condition.

If Timeout expires and the operation is not yet complete, the connector throws an exception.

UseMDX

Set this to true to pass MDX queries to Azure Analysis Services as-is.

Data Type

bool

Default Value

false

Remarks

You can execute SQL-92 SELECT queries to the views modeled by the connector; set this property to instead execute MDX queries directly to Azure Analysis Services.

See Retrieving Analysis Services Data for more information on querying Azure Analysis Services through the connector.

UserDefinedViews

A filepath pointing to the JSON configuration file containing your custom views.

Data Type

string

Default Value

""

Remarks

User Defined Views are defined in a JSON-formatted configuration file called UserDefinedViews.json. The connector automatically detects the views specified in this file.

You can also have multiple view definitions and control them using the UserDefinedViews connection property. When you use this property, only the specified views are seen by the connector.

This User Defined View configuration file is formatted as follows:

  • Each root element defines the name of a view.
  • Each root element contains a child element, called query, which contains the custom SQL query for the view.

For example:

{
    "MyView": {
        "query": "SELECT * FROM [adventureworks].[Model].Customer WHERE MyColumn = 'value'"
    },
    "MyView2": {
        "query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
    }
}

Use the UserDefinedViews connection property to specify the location of your JSON configuration file. For example:

"UserDefinedViews", "C:\Users\yourusername\Desktop\tmp\UserDefinedViews.json"
