How To Pass Output Parameter To Stored Procedure In SQL Server

In this tutorial, I will explain how to pass an output parameter to a stored procedure in MS SQL Server and also, we will see how to use stored procedure in SQL Server with an output parameter.

So, we will write the stored procedure for inserting the data for demonstration.

 

Stored Procedure in SQL Server

USE [DB_MANTRY]

--CREATED ON 08/12/2017 BY NIKUNJ SATASIYA

CREATE PROCEDURE BL_UserInfo_Ins -- BL_UserInfo_Ins is Procedure Name
    @UserName VARCHAR(50) ,
    @Password VARCHAR(50) ,
    @FirstName VARCHAR(50) ,
    @LastName VARCHAR(50) ,
    @Email VARCHAR(50) ,
    @Location VARCHAR(50) ,
    @Created_By VARCHAR(50) ,
    @ReturnValue INT = 0 OUT
AS
    BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.

        SET NOCOUNT ON ;
---Condition For Check if User exists or not if user does not exist then returns different message if exists returns different message

        IF NOT EXISTS ( SELECT  * FROM    BL_User_Info  WHERE   UserName = @UserName )
            BEGIN
                INSERT  INTO BL_User_Info
                        ( UserName ,
                          [Password] ,
                          FirstName ,
                          LastName ,
                          Email ,
                          Location ,
                          Created_By
                        )
                VALUES  ( @UserName ,
                          @Password ,
                          @FirstName ,
                          @LastName ,
                          @Email ,
                          @Location ,
                          @Created_By
                        )
--If User Successfully Registerd then we will return this Message as Output Parameter
                --SET @ReturnValue = 0
                SET @ReturnValue = @UserName + ' is Registered Successfully'
            END
        ELSE
            BEGIN
--If User already Exists We will return this Message as Output Parameter
                --SET @ReturnValue = 1
                SET @ReturnValue = @UserName + ' is Already Exists'
            END
    END

You can see the created stored procedure where we are sending @ReturnValue as an output parameter. And, it shows the appropriate message to the user based on the return value.
