Filter Transformation

Filter Transformation

Push a Filter transformation to the database to reduce the amount of data that the PowerCenter Integration Service processes. The PowerCenter Integration Service processes the Filter transformation if the filter expression cannot be pushed to the database. For example, if the filter expression contains an operator that cannot be pushed to the database, the Integration Service does not push the filter expression to the database.
The following table shows the pushdown types for each database to which you can push the Filter transformation:
