Experts,

I have a table of 9 columns with 4.6 million of records currently. one primary key col, 1 normal index col and a composite index of 2 cols.

Query is performing faster, where as, dml statements are very slow and it takes minutes to complete.

Pls advise as what are the various options that I can do to make dml statements also to perform well.

Thanks.

The idea presumably being that that waythe Queries will run as fast as the DML?

Q1) Do all DML statements run slowly, or is it just inserts or Updates or Deletes?
Q2) Are there any triggers on the table

Dear
I think there is so many updation or deletion in the given table due to these activitis the index entries get fragmented. so firstly rebulid your index and try to insert. it will work.
