Display Stored Procedure Output Parameter Value With Query Window in SQL Server 2012

In this article, I am showing you how to display return value from stored procedure output parameter in Query Window in SQL Server 2012.

Today, I have provided an article showing you how to display the return value from a Stored Procedure output parameter in a Query Window in SQL Server 2012. In this article, we create a Stored Procedure to avoid duplicate record insertion in the SQL Server database prior to insertion into the database. You can determine the value of the out parameter corresponding to the different condition as an out parameter. Let's have a look at a practical example. The example is developed in SQL Server 2012 using the SQL Server Management Studio. 

Output Keyword

The Output keyword to the parameters in the Stored Procedures can return the values of the parameters to the calling program. Now create a table named UserTable with the columns UserID, UserName. Set the identity property=true for UserID. The table looks as in the following:

Now create a Stored Procedure:

  1. Create PROCEDURE [dbo].[ExecuteProcedurewithOUTParameter]  
  2. (  
  3.       @UserName VARCHAR(100),  
  4.       @ResultValue int out  
  5. )  
  6. AS  
  7. BEGIN TRAN  
  8. IF EXISTS  
  9.     (  
  10.           SELECT * FROM Testoutvalue  
  11.           WHERE Name = @UserName  
  12.         )  
  13.      BEGIN  
  14.          SET  @ResultValue = -5  
  15.      END  
  16. ELSE  
  17.       BEGIN  
  18.            INSERT INTO Testoutvalue  
  19.                (  
  20.                    Name  
  21.                )  
  22.            VALUES  
  23.            (  
  24.                  @UserName  
  25.            )  
  26.            set @ResultValue = 1  
  27.      END  
  28. IF @@ERROR <> 0  
  29.      BEGIN  
  30.             ROLLBACK TRAN  
  31.       END  
  32. ELSE  
  33.       BEGIN  
  34.             COMMIT TRAN  
  35.       END  
  36. Select @ResultValue  
In the preceding Stored Procedure we declare an output parameter ResultValue. "If exists" is used to check the insertion record whether it belongs to the table or not. If the inserted record is already in the table then set the return status @ResultValue= -5 and the inserted record is not in the table by default; the successful execution of a Stored Procedure will return 1.

Now hit F5 to execute the Stored Procedure:

Now insert a value into the table using the Stored Procedure and check the result of executing the Stored Procedure with the output parameter values as follows:

  1. DECLARE @Outputparam VARCHAR(20);  
  2. Exec ExecuteProcedurewithOUTParameter 'ROhatashkumar', @Outputparam output  
Now execute the Stored Procedure. Now press F5 to run the Stored Procedure.

Every time you insert new records it will return the same above output. Now using a select statement to select the record from the table.

Now, we can execute the procedure with duplicate values to check how the RETURN statement works:

  1. DECLARE @Outputparam VARCHAR(20);  
  2. Exec ExecuteProcedurewithOUTParameter 'Rahul',@Outputparam output  
Output
