After the command for inserting the new user, use the following: select @@identity from MyTable
<cftransaction> <cfquery> What ever your SQL is to insert the new user </cfquery> <cfquery> select @@identity from MyTable </cfquery> </cftransaction> -----Original Message----- From: Chris Mueller [mailto:[EMAIL PROTECTED] Sent: Thursday, March 09, 2006 1:35 PM To: CF-Talk Subject: SQL-generated primary keys Here's a question I've been wrestling wtih. Suppose that there is an HTML form to create a new user. When the form is submitted, that user's information is added to the 'user' table. The table uses an auto-increment integer for its primary key/user id, so I'd like to grab that value for the newly created user. I've been using queries like this one: "SELECT MAX(user_id) FROM users", but I worry that if two users are created at the same time, then my query might give me the user id of the wrong user. Is there a better way to do this? Or maybe I shouldn't even worry about this? Thanks.
