Hint ordered and cartesian product
364677Jan 14 2011 — edited Jan 14 2011I have a query which needs to be tuned.
The initial Query does not show cartesian product in the plan , when I change the order of the tables in the from clause ( I have placed the least # of rows first and the most rows tables in the last) and I get MERGE JOIN CARTESIAN product the where clause remaining the same and the cost escalates from 7180 to 454M .
This happens with ordered hint.
