Pushdown Compatibility

The Data Integration Service can push transformation logic to the source database when the transformation contains operators and functions that the source supports. The Data Integration Service translates the transformation expression into a query by determining equivalent operators and functions in the database. If there is no equivalent operator or function, the Data Integration Service processes the transformation logic.
If the source uses an ODBC connection and you configure a database-specific ODBC provider in the ODBC connection object, then the Data Integration Service considers the source to be the native source type.
