Determining Identity Field Values

Using SQL Server and tables with identity fields (auto increment primary keys)? Then you have probably needed to know that assigned id and have resorted to using follow-up queries (probably within a transaction block). Well, here’s a much simpler (as well as safer) solution. Create a trigger on the table containing the code “SELECT @@IDENTITY AS id”. Now every time you do an INSERT operation the INSERT query will return a single row containing a single column called id which will contain the newly assigned id. (Applies to: ColdFusion All)
