Adding NOLOCK here, or almost anywhere, is a bad idea.

Look, if you really want to have dirty reads, change your connection string to use READ_UNCOMMITTED. That's the same as NOLOCK,...

You've identified some queries, but now you need to investigate their behavior within the system. The way to do this is to look at the execution plan in order to...

Thank you for those posts Grant. It helps to try and reset your view when there's so much going on that can drain us emotionally right now. I'm not...

GOOD MORNING GRANT!!!!

I recently saw an article about "Self-made men" and it expresses exactly the way I feel.  To summarize, I'm definitely not "self-made".  I'm where I'm at because...

Very kind words. Thanks.

Yeah, the curse and blessing of capturing the queries is you get to see exactly what's going on. Little things like that 19,700 executions accumulate in an insane manner to...

File... Open.

That's it. It's really straight forward.

and STRSALETYPE in ('I','W')

If those columns are in any of the tables where you're doing a LEFT JOIN, you should move these...

I assume we're talking about a batch here with multiple statements?

In that case, put Extended Events to work. You can create a session using the sql_statement_completed event for batches, or...

Nah, interrupt sounds fine. Ha! I'll see what I can do to get that fixed.

BTW, 3rd edition is WAY better than the first two.

Changes to the connection strings? ANSI settings? Differences in compiled execution plans? As above, wait statistics?

These are just a few of the possibilities. Also, you running a batch versus your...

Tons of stuff is faster in 2017. You should see what happened with 2019. They improved all sorts of stuff even more. It's honestly insane just how much better the...

OK. So, with ColNumber as the primary means of accessing the data, probably, and you should test this, not just trust some yahoo on the internet, that's your clustered key...
