Source Qualifier Transformation

Source Qualifier Transformation

The following table shows the pushdown types for each database to which you can push the Source Qualifier transformation:
Database
Pushdown Type
IBM DB2
Source-side, Full
Microsoft SQL Server

Netezza
Source-side, Full
Oracle
Source-side, Full
SAP HANA
Source-side, Target-side, Full
Sybase ASE
Source-side, Full
Teradata

Vertica

Microsoft Azure SQL Data Warehouse
Source-side, Full
Use the following rules and guidelines when you configure the PowerCenter Integration Service to push Source Qualifier transformation logic to a database:
  • Qualify the table name that you enter for a source filter or user-defined join when the Sequence Generator transformation is in the idle connection in a downstream Union transformation, Joiner transformation, or target, and the other connections are of a different database type. If you do not qualify the table name in this case, the PowerCenter Integration Service does not push all transformations to the database.
  • The session fails if you configure a user-defined join in the Source Qualifier transformation for shortcut objects and enable pushdown optimization.
The PowerCenter Integration Service processes the Source Qualifier transformation logic when any of the following conditions are true:
  • The transformation contains Informatica outer join syntax in the SQL override or a user-defined join. Use ANSI outer join syntax in the SQL override to enable the PowerCenter Integration Service to push the Source Qualifier transformation to the database.
  • The source is configured for database partitioning.
  • The source is an Oracle source that uses an XMLType datatype.
