    Experts,

    We have a procedure which select from a lot of tables. Will there be any performance improvement if we create a view for that select query instead of fetching directly from Table?

    Obviously yes, We'd implemented the same when we wanted to share our data to shared services team.

    I have a very hard time believing that a view improved performance unless it was an Indexed View.  A normal view is just an encapsulation of a query as if you wrote the query in a FROM clause or in a CTE.  Can you site any article or post any demonstrable code that proves that a normal view offers any type of a performance improvement?

    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.
