SQL Server: returns a unique identifier from a stored procedure

Question

Can I return a UNIQUEIDENTIFIER from a stored procedure using the RETURN statement, or is it just using the OUTPUT statement?

To return the user ID of UNIQUEIDENTIFIER:

CREATE PROCEDURE CreatePerson
    @Name NVARCHAR(255), 
    @Desc TEXT
AS
DECLARE @Count INT
DECLARE @JobFileGUID UNIQUEIDENTIFIER 

-- Check if job exists?
SET @Count = (SELECT COUNT(Name) AS Name FROM Person WHERE Name=@Name)

IF @Count < 1
BEGIN
    SET @PersonGUID = NEWID();

    INSERT INTO Person 
        (PersonID, Name, [Desc]) 
        VALUES (@PersonGUID, @Name, @Desc)

END

    SELECT @PersonGUID = Person.PersonID 
    FROM Person
    WHERE Name = @Name

    RETURN @PersonGUID
GO

thanks

Answer 1

In a stored procedure, only using the OUTPUT statement. In function - return.

Answer 2

Using:

CREATE PROCEDURE CreatePerson
    @Name NVARCHAR(255), 
    @Desc TEXT,
    @PersonGUID UNIQUEIDENTIFIER OUTPUT
AS
BEGIN

   SET @PersonGUID = ...

END

How to call:

DECLARE 
    @name NVARCHAR(255),
    @desc TEXT,
    @personGUID UNIQUEIDENTIFIER

SET @name = 'Bob'
SET @desc = 'One handsome man.'

EXEC [Database].[schema].CreatePerson @name, @desc, @personGUID OUTPUT

Answer 3

CREATE TABLE [dbo].[tbl_Clients]( [ClientID] [uniqueidentifier] NULL, [ClientName] varchar NULL, [ClientEnabled] [bit] NULL ) ON [PRIMARY]

GO

CREATE PROCEDURE [dbo].[sp_ClientCreate] @in_ClientName varchar(250) = "New Client 123", @in_ClientEnabled bit, @out_ClientId uniqueidentifier OUTPUT AS

SET @out_ClientId = NEWID();

INSERT INTO tbl_Clients(ClientId, ClientName, ClientEnabled) VALUES( @out_ClientId, @in_ClientName, @in_ClientEnabled)

DECLARE @return_value int, @out_ClientId uniqueidentifier

EXEC @return_value = [dbo].[sp_ClientCreate] @in_ClientName = N'111', @in_ClientEnabled = 1, @out_ClientId = @out_ClientId OUTPUT

SELECT @out_ClientId as N'@out_ClientId'

SELECT 'Return Value' = @return_value

GO
