How to Trap Return value of a Stored Procedure

[mukund]

How does one trap the Return value of a stored procedure.

I want to call one stored procedure, that return a Integer value by using the Return Statement.

I want to use this Return value in the calling Stored Procedure.

Hi, here it goes, run the script

/*Calling procedure*/
create  procedure proc1 
as
declare @result int
exec proc2 @result output
print @result
go
/*Another procedure*/
Create procedure proc2 @paramout int output
as
SET @paramout=1
go
exec proc1

Hope this helps

Thanks for the help Praveen.

But I used the following syntax

EXECUTE @OutAddrId = generateid 'AddrId', @HubId

Here @OutAddrId is the parameter in which the result will be returned.

generateid is the procedure being called with 'AddrId' and @HubId as two parameters.

create procedure usp_generateid @Addrid int,@hubid int
as
/*Do something */
Declare @outaddr int
IF @addriD>@hubid
BEGIN
    SET @outaddr=999
END
ELSE
BEGIN
    SET @outaddr=888
END
/*NOTE THAT U CANNOT RETURN NULL VALUES, ONLY INTEGER VALUES ALLOWED TO BE RETURNED*/ 
RETURN @outaddr /*Return the value using RETURN */
GO

/*Call Procedure*/
DECLARE @hubid int,
        @addrrid int,
        @OutAddrId int 
/*need to declare @OutAddrId this holds the result*/

/*Assign values */
SELECT @addrrid=11,@hubid=9

EXECUTE @OutAddrId = usp_generateid @addrrid,@HubId
PRINT @OutAddrId

Somethings to Note when u use the above method,
1>u can return only one value of integer type
2>Multiple values cannot be return
3>Mainly used for returning status of stored procedures or error codes.

I would be perfer to use the the one i posted before.
