Today I have a peformance issue where setting legacy cardinality estimator ON helps.

Hey Lowell!!!!
Great to see you out here in the wild.
Be a little cautious only on unique indexes when defining "used". The optimizer can actually reference a unique index in it's...

I'm not aware of this tool, so no real comment on it one way or the other.
However, the rules for any 3rd party solution for backups are very simple. Show...

To really get a grasp on SQL Server security, I'd suggest Denny Cherry's book on the topic. It's a little bit old at this point, but 90%+ of the...

I'm just still not getting it.
So, let's try this. You can't have a dynamic join. You have to define a join. Period. To dynamically change whether or not you're joining...

This needs pretty detailed analysis, and I'm sorry, I've been busy with work. I'll try to get into it again as soon as I can.

b.customer_b...

If you want to, get a copy of SentryOne Plan Explorer. It's free. It has a way to anonymize the plans. Post those and no code will be visible.
