How can one iterate over stored procedure results from within another stored procedure…without cursors?

Question

I\'m not sure if this is something I should do in T-SQL or not, and I\'m pretty sure using the word \'iterate\' was wrong in this context, since you should never iterate any

Answer 1

This may not be the most efficient, but I would create a temp table to hold the results of the stored proc and then use that in a join against the target table. For example:

CREATE TABLE #t (uniqueid int)
INSERT INTO #t EXEC p_YourStoredProc

UPDATE TargetTable 
SET a.FlagColumn = 1
FROM TargetTable a JOIN #t b 
    ON a.uniqueid = b.uniqueid

DROP TABLE #t
