Hi Alban, Thanks for the reply. 1) I'm using PostgreSQL 8.1; So, I can't use RETURNING clause! 2) The function I gave is just to put my understanding! Thanks for spotting the error though.

As John says, you're re-inventing the wheel that sequences solve. You could also get the id using INSERT .. RETURNING. You have another problem on your hands though. You have a naming conflict between your variable name and a column name in that second query: id and Id are the same.
