Question

Is there another way that I could do the following query

SELECT @MinID = MIN(ID), @MaxID = MAX(ID)
FROM #stp

WHILE (@MinID <= @MaxID AND IsNull(@MaxID, 0) > 0)
BEGIN

    SELECT @result_mstr_id = result_mstr_id
    FROM #stp
    WHERE ID = @MinID

    EXECUTE @err = f_rslm_publish @result_mstr_id

    UPDATE dbo.results
       SET result_stat_cd = CASE result_stat_cd
                                WHEN 'IP' THEN 'C'
                                WHEN 'IS' THEN 'S'
                                ELSE result_stat_cd
                            END
     WHERE result_mstr_id = @result_mstr_id

    SELECT @MinID = @MinID + 1

END

Its the typical loop being fed by a counter but could I re-write this to be one query?

Answer 1

You can’t. If you need to execute the stored procedure f_rslm_publish for every ID in the table #stp, then you’ll need to use a WHILE loop or a cursor.

Unless of course you can change the definition of the stored procedure f_rslm_publish, in which case it very well may be possible to rewrite it to accept a range of ID values (and possibly without also adding WHILE loops to the stored procedure code).
