SQL PO_ER_EQUE_INS in app engine PO_EROUT_AE fails on unique constraint error . The SQL PO_ER_EQUE_INS is failing on a unique constraint error in the step PO_EROUT_AE.CheckQue.Step02. This insert can be run more than once in the program (as evidenced by the comment /* Put any additional records back to the early queue table */)
In the NOT EXISTS subselect, there is a join on the COMMENT_ID field. The reason we get a unique constraint error is because the COMMENT_ID fields could both be NULL. On Oracle databases, NULL does NOT equal NULL in a SQL statement like this so this not exist fails - which means that the insert is attempted for data that already exists.
Error Position: 0
Return: 805 - ORA-00001: unique constraint (SYSADM.PS_PO_ER_E_MSGQUE) violated
