Like a total n00b, I'm going to ask here, how do I edit this page (or any page in the tutorial etc)?

@AaronBertrand make a PR to the GitHub repo (like I did here for the tutorial: github.com/StackExchange/StackExchange.DataExplorer/pull/109) and then ask a dev, probably Adam, to merge to master and re-deploy. Allow for 6 to 8 weeks ...

this is the help view: github.com/StackExchange/StackExchange.DataExplorer/blob/…

and the tutorial lives here: github.com/StackExchange/StackExchange.DataExplorer/tree/…

Hmm, better link for the tutorial: github.com/StackExchange/StackExchange.DataExplorer/tree/master/…

I'll have to wait until next week to publish anything about eachdb.

@rene This just came up elsewhere and felt compelled to mention mssqltips.com/sqlservertip/7144/… / mssqltips.com/sqlservertip/7145/…

(Also in my defense I did not write the opening paragraph to part 1. I had to read it three times to understand it, and I'm not sure I succeeded.)

What you won't see on their site :-)

@AaronBertrand I assumed the SQL team re-implemented FORMAT to be as performant as CONVERT but it look like they literally call out to the CLR. Lesson for today: Always Test for performance, even for things that come for "free" out of the box...
