I'm sure someone like Naomi can write these in her sleep, but anyone want to take a crack? I use this one as an example in SQL sessions to demonstrate a language feature added in SQL 2005 that doesn't always get as much attention as it should.

I know of 3 ways to make the desired output. I am not giving them up, though. One version works in any versions of SQL Server and also in FoxPro as well.
