检查记录值更新存储过程MS SQL

后，该执行存储过程检查记录值更新存储过程MS SQL

EXEC dbo.Web_update 
@hHomeEmail = '[email protected]', 
@pPassword = 'XXXXX', 
@mMemberID = '123456'

存储过程

UPDATE Member 
SET pass_w = @pPassword, 
HomeEmail = @hHomeEmail 
WHERE [email protected];

我想检查HomeEmail的值和更新后pass_w如果NULL或不要因该调用返回布尔值。

---------- ---------- UPDATE

USE [Test] 
GO 
/****** Object: StoredProcedure [dbo].[Web_update] Script Date: 03/21/2017 12:37:46 ******/ 
SET ANSI_NULLS ON 
GO 
SET QUOTED_IDENTIFIER ON 
GO 
-- =============================================

ALTER PROCEDURE [dbo].[Web_update] 
    -- Add the parameters for the stored procedure here 

    @hHomeEmail nvarchar(10) = NULL, 
    @MemberNo nvarchar(10) = NULL, 
    @pPassword nvarchar(10) = NULL, 
    @mMemberID INT 

AS 
BEGIN 
    -- SET NOCOUNT ON added to prevent extra result sets from interfering with SELECT statements. 
    SET NOCOUNT ON; 

    -- Insert statements for procedure here 
    UPDATE Member SET pass_w = @pPassword, HomeEmail = @hHomeEmail WHERE [email protected]; 

    -- Insert statements for procedure here 
    SELECT CASE WHEN EXISTS (SELECT 1 FROM member WHERE [email protected] AND pass_w = NULL OR HomeEmail= NULL) 

     THEN CAST(1 AS BIT) 
      ELSE CAST(0 AS BIT) END 


END

现在我想检查：

pass_w = NULL

pass_w = ''

HomeEmail = NULL

HomeEmail = ''

如果它们中的一个然后浇铸（1 AS BIT）

ELSE CAST（0 AS BIT）

为什么所有首先在这些列中归零？ –

可能重复的[Get Updated Row]（http://stackoverflow.com/questions/1367018/get-updated-row） –

为什么允许null HomeEmail和pass_w都被添加到成员表中。现在会员可以在线登录，但必须先更新HomeEmail和pass_w才能继续。 –

您可以将输出参数添加到您的存储过程：

CREATE PROCEDURE dbo.Web_update 
(
    @hHomeEmail = varchar(10), 
    @pPassword = varchar(10), 
    @mMemberID = varchar(10) 
    @@pIsNull bit OUTPUT 
) 
AS 
UPDATE Member 
SET pass_w = @pPassword, 
HomeEmail = @hHomeEmail 
WHERE [email protected]; 

SELECT @pIsNull = CAST(CASE WHEN EXISTS (
              SELECT 1 
              FROM Member 
              WHERE [email protected] 
              AND pass_w IS NULL 
              AND HomeEmail IS NULL) THEN 1 
          ELSE 0 END As Bit)
