How do I disable query results when executing a stored procedure from a stored procedure?

You can discard the resultsets in SQL Server Mgmt Studio 2005 by following the steps below:

• Right-click in the query window
• Choose "Query Options"
• Click on the "Results" "node" in the left panel tree view
• Check "Discard results after execution" in the center/right of the form

You can try it on

DECLARE @i int
SET @i = 1
WHILE (@i <= 100)
  BEGIN
    SELECT @i as Iteration
    SET @i = @i + 1
  END

you could insert the results into a temp table, then drop the temp table

create table #tmp (columns)

while
    ...
    insert into #tmp exec @RC=dbo.NoisyProc
    ...
end
drop table #tmp

otherwise, can you modify the proc being called to accept a flag telling it not to output a result-set?

I know this question is old, but you could set the SET NOCOUNT ON to prevent the SP to output a message for every row.
