You should ask this on the users list, not the java list ([email protected]). When you do, please include the output of EXPLAIN, if that doesn't already answer your question for you.

I have to delete 10,000 records and the query framed is something like this : delete from naptrrecord where id in (1,2,3,4....,10000) and id not in(111,222.....); The records that we are trying to delete are not sequential so we are sending all the IDs. This query is ver slow. Can you please give me some ideas to optimize it.
