Insert done fast in SQL*Plus but slow in Reports trigger

Hi all,

I am experiencing wiered problem.

I have a requirement of inserting rows into a temp. table in Before Report trigger so that the report query runs on that table.

I am able to test insert in TOAD and SQL*Plus and working very fast. Ex. for 800 rows, it takes 2 min.

But when I use the same Insert statement in Before Report trigger in the report, it goes on and on. In before report trigger, I first truncate that table.

Can someone tell me why it is happening so?

TIA.

Any idea?

Thanks,
