Understanding the Default Query

Understanding the Default Query

The default query is a SELECT statement in the Application Source Qualifier transformation. The Designer creates the default query based on the following:
  • Connected transformation input and output ports
  • Transformation settings
  • Relationships between sources connected to the same Application Source Qualifier
The PowerCenter Integration Service uses the default query as the basis for the extract query for the session. The following factors cause the PowerCenter Integration Service to alter or expand the default query:
  • The PowerCenter Integration Service process code page differs from the code page of the PeopleSoft underlying database, which requires the PowerCenter Integration Service to perform code page translations.
  • You enter a PeopleSoft language code in the application connection for a PeopleSoft source, which requires the PowerCenter Integration Service to join source tables with their related language tables.
The PowerCenter Integration Service writes the extract query into the session log.
The default query includes only the ports in the Application Source Qualifier that are connected to other transformations.
Although all ports in the source definition are connected to the Application Source Qualifier, only three ports are connected to the Expression transformation. In this case, the Designer generates a default query that selects only those three columns: 
SELECT PS_PROJ_VARY_BA_VW.SETID, PS_PROJ_VARY_BA_VW.BUSINESS_UNIT, PS_PROJ_VARY_BA_VW.PROJECT_ID FROM PS_PROJ_VARY_BA_VW
