存储过程如果存在则不给出正确答案

Question

我创建了一个 sql 2005 存储过程来告诉我我正在搜索的 CRID 是否得到了主管的批准。 [SuperApproved] 是一个位，[CRID] 是 char(36)。即使 CRID 不存在，我仍然得到 1。 写这个有什么帮助吗？

USE [cr_Saturn2]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author:  Randy Baker
-- Create date: 10/12/2010
-- Description: Check for Approved CRID in CostReportTracking
-- =============================================
alter PROCEDURE [dbo].[st_Is_CostReportApproved]
 -- Add the parameters for the stored procedure here
 @myECR char(36) = null  
AS
BEGIN
 -- SET NOCOUNT ON added to prevent extra result sets from
 -- interfering with SELECT statements.
 SET NOCOUNT ON;

if exists(
 select [CRID]
 from [dbo].[CostReportTracking]
 where [SuperApproved] = 1)

 -- exists- cost report is Approved by Supervisor
 select 1
else
 -- does not exist
 select 0    
END

Answer 1

我认为您需要在某处添加 和 [CRID] = @myECR 。现在您只需检查是否有任何记录已超级批准。
