Informix and Transformation Datatypes

The following table compares Informix datatypes to the transformation datatypes that display in the Source Qualifier, Lookup, and Stored Procedure transformations. You can change the transformation datatype within the mapping, and the Integration Service converts the data. However, the datatype in the Source Qualifier, Lookup, and Stored Procedure transformations must match the source datatype. If they do not match, the mapping is invalid.

Only the Informix Text datatype appears as the transformation Text datatype in Source Qualifier, Lookup, and Stored Procedure transformations. However, use the transformation datatypes Text and String interchangeably.
