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.
Regards,
Siva.

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
inthat second query: id and Id are the same.
