    Description

      This is a follow-up to TRAFODION-2127.

      The code delivered for TRAFODION-2127 puts in the infrastructure to create a temp table, but it does not provide heuristics to decide automatically when to do this transformation. CQD CSE_USE_TEMP can only be used to force the transformation ON or OFF.
