I have been playing around some more with SQL Azure in order to get ready for an upcoming presentation, so I thought I would share some of the T-SQL commands in the script below. I have a partial copy of the sample AdventureWorksLT2008R2 database installed on my SQL Azure logical “server” in the Southern US data center before this demo starts. You need at least the November CTP of SQL Server 2008 R2, in order to talk to SQL Azure with SSMS.

I have mainly just trying different commands to see what works and what does not work in SQL Azure, so I hope you find this interesting and useful.
