store procedure over a list

    Hello,

    I have a stored Procedure which takes an integer as a parameter. I would like to execute that stored procedure over a list of integer while executing. I do not want to make any change to the procedure. Is there a way like executing the procedure using "in" or something like:

    exec procThis in (1,2,3,... )

    Thanks

    create another procedure that can execute the proc in question via a loop.

    You can allow this new proc to accept the delimited list and then parse that list into rows via a string splitter - then call the original proc for each parameter in that list.

    Another option is to rewrite it so it will function as you desire.

    As far as I'm aware a cursor is the only way to do this.

    --Create #temp table and insert numbers

    DECLARE int_cursor CURSOR

    FOR SELECT intVal FROM #temp

    OPEN int_cursor

    DECLARE @currInt INT

    FETCH NEXT FROM int_cursor INTO @currInt

    WHILE @@FETCH_STATUS = 0

    BEGIN

    --Your code here (using the @currInt variable)

    END

    CLOSE db_cursor

    DEALLOCATE db_cursor

    Cursors tend to be pretty slow though, so as a rule I would try avoiding them. Without seeing what you are trying to do though it is hard to suggest an alternative.

    Hope that helps!

    I'm not so sure that's true. Depending on what the stored procedure actually does, it may be VERY beneficial to performance and resource usage to rewrite the procedure to operate in a Set-Based fashion instead of RBAR.

    --Jeff Moden

    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.
