存储过程是否存在没有给出正确答案

Question

我创建了一个sql 2005存储过程来告诉我，如果我正在搜索的CRID是由主管批准的。 [SuperApproved]有点儿，[CRID]是char（36）。即使CRID不存在，我仍然得到1. 任何帮助写这篇文章？

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

我认为你需要在某处添加一个and [CRID] = @myECR。现在你只是检查是否有任何记录已经超级赞成。
