I guess I'm confused by the problem. When I ran the test as presented I got the error you described, but I got the same error even when I commented...

I think you're correct on my errors in the article. Thanks for the input. I'm not sure if Steve will let me do an update, but I'll check.

I suspect it's...

What about scans & I/O? Are they on identical servers? What about weirder stuff like tempdb usage or log backups or other processes causing locks, etc.

WHERE 1 = CASE WHEN @CandidateId = 0 THEN 1

WHEN ID_Kandidat = @CandidateID THEN 1

ELSE 0

Whew. I thought I was going nuts for a minute when that turned out not to be as easy as I originally thought. We all came to the same conclusion...

But, of course, never on a production system where we need to have up to the minute data recovery, right.

100,000 records is just going to take a long time to return especially when you add x number of columns, latency, network traffic, etc. It's also probably going to ignore...

OK. Maybe I'm wrong.

I tried several things and the original is still the performing best.
