SQL Server: Retourne un identifiant unique de la procédure stockée

Question

Puis-je retourner UNIQUEIDENTIFIER à partir d'une procédure stockée à l'aide de l'instruction RETURN ou est-ce uniquement à l'aide de l'instruction OUTPUT?

i.e. pour retourner le PersonID 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 

Merci

Answer 1

procédure stockée - uniquement en utilisant l'instruction SORTIE. En fonction - retour.

Answer 2

Utilisation:

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

    SET @PersonGUID = ... 

END 

Comment appeler:

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
