    Thank you for sharing this article. Actually i had this question posted in forums also, so far no response, would like to know your thoughts please.

    I have a view which is performing a order by on three columns a/b/c, a/b are indexed and is from table 1, c is from table2. How are the indices used in this case? How does sql use two different indices on two different tables? I am trying not to use indexed views or is indexing the view only way?

    I don't want to hi-jack this thread by answering a forum post. I'll take a look at your original post and answer there.

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
