I'm still looking forward to the sky writing...

--Jeff Moden

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is not.
Just because you can do something in PowerShell, doesnt mean you should. Wink

Apparently it's not working: http://146.176.166.22/~andrew/s2/execsql.pl Suffered: 500 Internal Server Error

Those interactive ones are ripe for SQL Injection attacks.

Hello,

I have been using http://www.sql-ex.ru/.
Great site. Full of excersises with varying difficulty.

Joe,

I 'll buy your book. Thanks for your note.

And, I strongly disagree asking Joe for the scripts and text. I don't believe we are being respectful enough.

That's pretty cool. One recommendation would be that if anyone wants to use XML to do a split, you might not want to work for them. :-D

My other recommendation would be that it would really be helpful to neophytes if you provided code to generate, say, a million rows of sample data so that people can also learn about how to make such things fast.
