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

Insert the results of the stored proc into a temporary table and join this to the table you want to update:

INSERT INTO #WorkTable
EXEC usp_WorkResults

UPDATE DataTable
  SET Flag = Whatever
FROM DataTable
INNER JOIN #WorkTable
  ON DataTable.Ket = #WorkTable.Key
