When defining a schema, some data may be converted during processing. This page describes how this data is converted.

Fields with Spaces

Spaces included as part of a field name are replaced with an underscore _.

CSV with Headers

If providing a CSV file with a header row, these rules are applied to generate column names:

  • Special characters are replaced with a question mark ?.
  • Spaces are replaced with an underscore _.
  • If a column name is blank, it is replaced with f1f2f3, and so on.
  • If a column name starts with a number, it is prefixed with an underscore _.
  • If a column name is repeated, it is appended with 234, and so on.

Unlimited-Precision Data Types

Unlimited-precision data types, such as XML decimal, are converted to double data types and therefore have a precision limit imposed on them that could, as a result, truncate data.

The precision limit is within the range of the min and max values of a signed long, which is –2,147,483,648 to 2,147,483,647. If outside of this range, consider using a string data type.

Non-Primitive Data Types

Primitive data types including string, integer, long, date, float, double, and boolean are fully supported. When creating a new custom flat or hierarchical schema or editing any schema, these data types are available to choose from in the Type dropdown by default. For new custom schemas, non-primitive data types such as datetime are not supported.

However, non-primitive data types are supported for schemas that are automatically generated from a server-based connector or were mirrored from such a schema. After they are generated, such schemas can also be manually edited in the custom schema editor. If the schema contains any non-primitive data types, these will also be listed in the Type dropdown when editing such a schema.

Null Values

Fields that have a null value are included in the resulting data schema despite having no data. As they also have no defined data type, these fields are treated as having a string data type.

Data Types in Manually Defined Schemas

For manually created flat and hierarchical custom schemas, the user-provided data type is for display purposes only. Jitterbit Harmony handles all fields within manually defined schemas as strings regardless of the data type label.

For custom schemas created by mirroring a schema from a server-based activity, the data type reflects actual data type usage for respective fields.
