Well... I'm officially neck-deep in SQL.

3 months ago? Hadn't touched SQL beyond issuing a couple of SELECT statements.

Now? Writing an HMAC-based-login system in PHP with account-credentials for the MySQL login that can only call specific stored SQL functions that operate as black-boxes and return single-value responses or null.

Um... yeah... I should have picked this stuff up years ago so I could put it on my resume.
