SQL Server:从存储过程返回uniqueidentifier

Question

我可以使用RETURN语句从存储过程返回UNIQUEIDENTIFIER,还是仅使用OUTPUT语句？

即返回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

谢谢

Answer 1

在存储过程中 - 仅使用OUTPUT语句.在功能 - 返回.

Answer 2

使用:

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

   SET @PersonGUID = ...

END

怎么称呼:

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

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

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