Sorry I didn't get it exactly. Because the same function (send e-mail) I am able to create at my end, but our client is not able to create it at their end. 1. Is there some problem in installation? Or 2. Problem with system user permission executing that database? OR 3. Problem With Database user permission? Now how to change permission of that user to be able to create this function? ---------------------------- If you created an untrusted function as user "dbUSER" then it was a superuser too. Honest. ---------------------------- Thanks Dinesh ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
