Execute stored procedure with an Output parameter?

I have a stored procedure that I am trying to test. I am trying to test it through SQL Management Studio. In order to run this test I enter ...

exec my_stored_procedure 'param1Value', 'param2Value'

The final parameter is an output parameter. However, I do not know how to test a stored procedure with output parameters.

How do I run a stored procedure with an output parameter?

The easy way is to right-click on the procedure in Sql Server Management Studio (SSMS), select 'Execute stored procedure..." and add values for the input parameters as prompted. SSMS will then generate the code to run the procedure in a new query window, and execute it for you. You can study the generated code to see how it is done.

you can do this :

declare @rowCount int
exec yourStoredProcedureName @outputparameterspOf = @rowCount output

Return val from procedure

ALTER PROCEDURE testme @input  VARCHAR(10),
                       @output VARCHAR(20) output
AS
  BEGIN
      IF @input >= '1'
        BEGIN
            SET @output = 'i am back';

            RETURN;
        END
  END

DECLARE @get VARCHAR(20);

EXEC testme
  '1',
  @get output

SELECT @get 

Check this, where the first two parameters are input parameters and the 3rd is an Output parameter in the Procedure definition.

DECLARE @PK_Code INT;
EXEC USP_Validate_Login 'ID', 'PWD', @PK_Code OUTPUT
SELECT @PK_Code

#Procedure Example :

Create Procedure [dbo].[test]
@Name varchar(100),
@ID int Output   
As  
Begin   
SELECT @ID = UserID from tbl_UserMaster where  Name = @Name   
Return;
END     

#How to call this procedure

Declare @ID int    
EXECUTE [dbo].[test] 'Abhishek',@ID OUTPUT   
PRINT @ID

First, declare the output variable:

DECLARE @MyOutputParameter INT;

Then, execute the stored procedure, and you can do it without parameter's names, like this:

EXEC my_stored_procedure 'param1Value', @MyOutputParameter OUTPUT

or with parameter's names:

EXEC my_stored_procedure @param1 = 'param1Value', @myoutput = @MyOutputParameter OUTPUT

And finally, you can see the output result by doing a SELECT:

SELECT @MyOutputParameter 

How about this? It's extremely simplified:

1. The SPROC below has an output parameter of @ParentProductID

2. We want to select the value of the output of @ParentProductID into @MyParentProductID which is declared below.

3. Here's the Code:

    declare @MyParentProductID int
   
    exec p_CheckSplitProduct @ProductId = 4077, @ParentProductID =  @MyParentProductID output
   
    select @MyParentProductID
   

With this query you can execute any stored procedure (with or without an output parameter):

DECLARE @temp varchar(100)  
EXEC my_sp
	@parameter1 = 1, 
	@parameter2 = 2, 
	@parameter3 = @temp output, 
	@parameter4 = 3, 
	@parameter5 = 4
PRINT @temp

Here the datatype of @temp should be the same as @parameter3 within your Stored Procedure.

Try this; it's working fine for the multiple output parameter:

CREATE PROCEDURE [endicia].[credentialLookup]
@accountNumber varchar(20),
@login varchar(20) output,
@password varchar(50) output
AS
BEGIN
SET NOCOUNT ON;
SELECT top 1 @login = [carrierLogin],@password = [carrierPassword]
  FROM [carrier_account] where carrierLogin = @accountNumber
  order by clientId, id
END

Try for the result: 
SELECT *FROM [carrier_account] 
DECLARE @login varchar(20),@password varchar(50)
exec [endicia].[credentialLookup] '588251',@login OUTPUT,@password OUTPUT
SELECT 'login'=@login,'password'=@password

CREATE PROCEDURE DBO.MY_STORED_PROCEDURE
(@PARAM1VALUE INT,
@PARAM2VALUE INT,
@OUTPARAM VARCHAR(20) OUT)
AS 
BEGIN
SELECT * FROM DBO.PARAMTABLENAME WHERE PARAM1VALUE=@PARAM1VALUE
END

DECLARE @OUTPARAM2 VARCHAR(20)
EXEC DBO.MY_STORED_PROCEDURE 1,@OUTPARAM2 OUT
PRINT @OUTPARAM2

Here is the stored procedure

create procedure sp1
(
@id as int,
@name as nvarchar(20) out
)
as
begin
select @name=name from employee where id=@id
end

And here is the way to execute the procedure

 declare @name1 nvarchar(10)
    exec sp1 1,@name1 out
    print @name1

Please check below example to get output variable value by executing a stored procedure.

    DECLARE	@return_value int,
	@Ouput1 int,
	@Ouput2 int,
	@Ouput3 int

EXEC	@return_value = 'Your Sp Name'
		@Param1 = value1,
		@Ouput1 = @Ouput1 OUTPUT,
		@Ouput2 = @Ouput2 OUTPUT,
		@Ouput3 = @Ouput3 OUTPUT

SELECT	@Ouput1 as N'@Ouput1',
		@Ouput2 as N'@Ouput2',
		@Ouput3 as N'@Ouput3'

Here is the definition of the stored_proc:

create proc product(@a int,@b int)
as
return @a * @b

And, this is executing it from Python: conn = pyodbc.connect('...') cursor = conn.cursor()

sql = """
SET NOCOUNT ON
declare @r float
exec @r=dbo.product 5,4
select @r
"""
result = cursor.execute(sql)
print (result.fetchall())
