HI,
Query from a 9i db. Suggestions? Explain plan cost is 296787. Ouch.
Any help would be much appreciated.

cost is completely irrelevant. Ignore it. posting the explain plan and
the number of records in each table is far more helpful.
some quick points:
WHERE ( WWLINK_DIE.UPDATE_DM >= to_date('10/08/2003 05:23:25') OR WWLINK_THA_DATASET.UPDATE_DM >= to_date('10/15/2003
02:02:22'))
forces a full table scan. do you want an index scan? then you need a
function based index.
i cant give you any more info than that. i need more information.
Hi,
Don't need function based index here.
