ahixon2112 on Twitter just rocked my world! I was talking about converting from MS SQL Server to MySQL and theorized that one of the only things I would have to change is my use of @@Identity to get the most recently created auto-ID value. I thought that I would have to convert all those @@Identity statements into LAST_INSERT_ID() statements. But, ahixon2112 stated that MySQL built in the @@Identity support for better portability.
To test this, I ran a quick SQL INSERT script followed by "SELECT (@@Identity AS id)" and HOLY COW! It worked! Rock on!
