Thanks.

take references to the elements of %ages and store them in @insert so that you can modify @insert via %ages.

Yes, that is what I am looking for. Thank you very much. And yes, I will have problem on:

$sqlquery->execute(@insert);
[download]

As I have to dereference them.

The purpose of this idea is to speed up the SQL process. But now, it seems this idea can't work.

Again, a big thank you to all of you.
