in reply to Excessive execution time passing parameters to Oracle

One possible explanation. If not, you'll have to try out explain plan with the hard-coded values and with the bound values, with auto-trace on - you will probably find some difference in Oracle's behaviour.

Essesntially, I'm saying that it's unlikely to be a Perl problem
