In general I assume there is no single source of information, just lots of experience & knowledge built over the years, and a lot of exploration to build that knowledge over time.

That's a pretty fair assessment.

Or do you just have some really good contacts with MS?

Sadly, no.

Excellent and very throught provoking series.

Do we think the mix up of RULEOFF/RULEON in SQL 2005 was a deliberate ploy or purely accidental by the MS developers?

It's usually safe to assume cock-up over conspiracy ;-)

Awesome, just awesome.

Plus this:

In SQL Server 2005, SHOWOFFRULES displays a list of rules that are ON, and SHOWONRULES displays rules that are OFF, which is actually quite funny.


Just made my day! :-D


Agreed - quite funny.
