# TC to test temp-table DML optimization changes for correctness   #
# Sceanrio covered:						   #
# 1. autocommit: operating all dml stmt with auto-commit on        #
# 2. begin-commit-rollback: sequence of dml stmt with trx that is  #
#    is committed and rollback post commit to see effect.          #
# 3. begin-rollback: sequence of dml stmt with trx rollback.       #
#    given that undo logs are generated for trx, rollback should   #
#    succeed.                                                      #
# 4. begin-savepoint-rollback-commit: dml stmt with trx involving  #
#    savepoint.                                                    #
