WHY U DONT USE THE PIVOT/UNPIVOT STATEMENTS TO TRANSFORM COLUMN DATA INTO MANY COLUMNS??
Posting in call caps is considered yelling. No need to yell, we are all friends around here.
The PIVOT statement would work for this also. However, it generally will not perform as well as a cross tab. Additionally, at least for me, they are a lot easier to read and understand.
Take a look at the articles referenced in my signature about cross tabs. As always, Jeff Moden does an amazing job demonstrating various methods for this type of thing along with performance tests.
