    What's wrong with the pivot function I gave you?

    1) I would shut down sql server and other processes on the box and run chkdisk.exe (you can use -? to get options) to find possibly bad...

  • RE: Funny calculation and grouping problem

    I just had a very quick glance at the xml plan for both operations and I can't see any difference.
