Meme Monday – Dumb Questions

Here I am, jumping in again for this month’s Meme Monday.  For June, Tom LaRock(t|b) is asking for our dumb SQL questions.

Can you disable the transaction log?

The answer is, emphatically, “NO”.  Most people I’ve run into ask this because they struggle with delays caused by locking and deadlocks, or they’re looking for ways to speed up inserts.  The facts are that without the transaction log and everything that comes with it, you lose the ACIDity (Atomicity, Consistency, Isolation, Durability) within the database.  In other words, you lose all the elements that control and maintain the integrity of your data while thousands of different statements are trying to get at it.

So the next time someone comes to you asking about just disabling this key feature, send ’em to this great article by Steve Jones.

    Wow, that’s a good one…I’ve never heard that one!

    1. Mike Fal says:

      Regrettably, I’ve heard it a couple times. And it’s definitely a “head shaker”.

  2. Can’t we just add ‘WITH(NOLOCK)’ to everything?

    These are great questions. While it exposes the ignorance of the people asking it, it does bring to light the problem, or at least the symptom of the problem. Hopefully the person answering the question can use that as a first step to get to the root issue.
