SQL & PL/SQL

Hi,

I need a temp table to store few IDs (which I select from a complex query). I would be deleting the data from the temp table at the end of the session.

From a performance perspective, I was wondering if I should be using a GLOBAL temporary table or just a regular table in which I will manually delete rows at the end.

The tkprof showed using the global temp table expensive. If yes, I just want to confirm it and know why it is the case.

Thanks!
