    WOW! After years of being hidden, CTE Opthints just got made IBM Official... Check out the, slightly late :), announcement in the Aha Idea from Walter:

    DB24ZOS-I-717

    Now we just have to wait for official docu... If you cannott wait for the official docu you can still read my Blog all about these fantastic beasts here:

    If you ever wanted to lock a query to stop table access flips these are you go to fix!

    "Now we just have to wait for official docu..."

    I did ask - however "the development team ... say that they would like to document CTE optimization hints at some point in the future. However, right now, the feature should be used under the direction of IBM support only."
