Steps to Reproduce

Specify an optimizer hint in the SQL for a Connect SQL rule.

Root Cause

Pega filters out data that is considered to be comments in the custom SQL contained in RDB-List rules. Oracle hints resemble comments and are filtered.


Specify the hints using Asls keyword.

Refer to SA-10763 support article on the PDN. Its link is given below.

The Help file page for Connect SQL form - Data mapping contains more information on the AsIs keyword and its use. Search for AsIs in Help.
