Good or bad, as long as stuff isn't plagiarized.

In my experience, it depends on the number of rows. Opening XML is somewhat expensive inside SQL Server. I've found that if I'm moving fewer than ~100 rows (and yes,...

Risking a pork chop, I'm going to disagree with Jeff on this.

You should look at option 1, but as was mentioned before, create a schema for the views. Also, I'd...

Just to pile on a bit, I find the DTA to be very problematic. I've given it substantial loads to see what it will do and it misses very obvious...

You have two things going on. First, you have data in the database. The more data, the bigger the files. To make the testing system smaller, remove unused data.

Personally, I'd stick with RAID 10. The added safety is worth more than a small increase in speed.

You've collected performance data and the bottleneck is I/O and you've tuned the...

That's a very open ended question. I don't know what kind of work you need done.

I'd start them off writing TSQL queries so that they begin to understand how databases...

Yep, right there in the BOL. I had to look it up just to verify.

There are three ways you can do this easily. Use TOP, MAX or ROW_NUMBER. I'd recommend testing your system with TOP or ROW_NUMBER because, in my experience, MAX generally doesn't...

So did you try what I laid out in the post you put up yesterday?
