Get result parameter of stored procedure in exec clause - sql

Question

I have a stored procedure that returns multiple parameters:
CREATE PROCEDURE [dbo].[TestSP]
#Test1 INT
, #Test2 UNIQUEIDENTIFIER
--some inserts and alters here
SELECT TOP 1
#Parameter1 AS Design
, #Parameter2
, #Parameter3
FROM Table
I want to use EXEC into another stored procedure and get ONLY #Parameter1 (Design)
So I want to get #Parameter1 after EXEC stored procedure, so I think about OUTPUT, but it doesn't work, is there a way to achieve this?
CREATE PROCEDURE [dbo].[SecondStoredProcedure]
#Sender1 INT
, #Sender2 UNIQUEIDENTIFIER
DECLARE #ReturnedParameter1 INT
EXEC [dbo].[TestSP] #Test1 = #Sender1, #Test2 = #Sender2 OUTPUT [Design]
INTO #ReturnedParameter1
SELECT #ReturnedParameter1

Answer 1

That procedure creates a resultset, and has no output parameters. You can capture a resultset with insert into ... exec, like this:
use tempdb
go
CREATE PROCEDURE [dbo].[addDesign]
#Test1 INT
,#Test2 UNIQUEIDENTIFIER
as
begin
--some inserts and alters here
SELECT
1 AS Design
, 2 as Foo
, 3 as Bar
end
go
declare #rv table(Design int, Foo int, Bar int)
declare #test2 uniqueidentifier = newid()
insert into #rv
exec addDesign 1, #test2
declare #design int = (select Design from #rv)
select #design

Answer 2

I suggest using an output parameter as explained in the official docs.
Here is how your code might look in this case:
use tempdb
go
create procedure [dbo].[addDesign]
(
#Test1 int
, #Test2 uniqueidentifier
, #Design int out
)
as
begin
set nocount on;
--some inserts and alters here
-- Set the return parameter
set #Design = #Parameter1;
-- Select the return results
SELECT TOP 1
#Parameter1
, #Parameter2
, #Parameter3
FROM dbo.MyTable;
-- Return status code, proc ran OK
return 0;
end
go
create procedure [dbo].[SecondStoredProcedure]
(
#Sender1 int
, #Sender2 uniqueidentifier
)
as
begin
set nocount on;
declare #ReturnedParameter1 int;
exec dbo.TestSP #Test1 = #Sender1, #Test2 = #Sender2, #Design = #ReturnedParameter1;
select #ReturnedParameter1;
-- Return status code, proc ran OK
return 0;
end
go
Note: This demonstrates the 3 ways information can be returned from a stored procedure, the result code (only 1), output parameters (0-N) and result sets (0-N).
