Greg,
Correct me if I am wrong but both will return duplicates since the OR
operator is used.
The primary key is on PRD_LVL_CHILD.PRDMSTEE.

Hi Suhen,
The UNION ALL will return duplicates from the two queries, whereas the
original query will not, right? So the query is tuned, but it returns a
different result set.
Do you agree?
Best regards,
- Greg
