查询结果与存储过程中的查询不同

Question

我做了一个查询来填充我的表并将其转换为存储过程。

CREATE PROCEDURE [dbo].[sp_getSAPCMTX] 

@sSDate varchar(10), 
@sEDate varchar(10), 
@sBranch varchar(4000) 

AS 

DELETE FROM SAPCMTX 
WHERE DocDate BETWEEN @sSDate AND @sEDate AND 
StoreCode IN (SELECT Item FROM dbo.SplitStrings(@sBranch , ',')) 

INSERT INTO SAPCMTX 
SELECT * FROM Table T0 
WHERE T0.DocDate BETWEEN @sSDate AND @sEDate AND T0.DataSource<>'O' AND 
    T1.TreeType<>'I' AND T0.DocType = 'I' AND 
    StoreCode IN COLLATE DATABASE_DEFAULT IN (SELECT Item FROM 
    dbo.SplitStrings(@sBranch , ',')) 
GO 

要运行它我用这个命令

EXEC [dbo].[sp_getSAPCMTX] 
     @sSDate = '3/8/2016', 
     @sEDate = '3/8/2016', 
     @sBranch = '002' 

它返回33行，但，当我尝试作为TSQL单独运行它返回34行。

DECLARE @sSDate varchar(10) 
DECLARE @sEDate varchar(10) 
DECLARE @sBranch varchar(4000) 

SET @sSDate = '3/8/2016' 
SET @sEDate = '3/8/2016' 
SET @sBranch = '002' 


DELETE FROM SAPCMTX 
WHERE DocDate BETWEEN @sSDate AND @sEDate AND 
StoreCode IN (SELECT Item FROM dbo.SplitStrings(@sBranch , ',')) 

INSERT INTO SAPCMTX 
SELECT * FROM Table T0 
WHERE T0.DocDate BETWEEN @sSDate AND @sEDate AND T0.DataSource<>'O' AND 
    T1.TreeType<>'I' AND T0.DocType = 'I' AND 
    StoreCode IN COLLATE DATABASE_DEFAULT IN (SELECT Item FROM 
    dbo.SplitStrings(@sBranch , ',')) 
GO 

任何想法为什么结果有差异，考虑到它基本上是相同的查询？

这里有两种可能性，可以帮助你得到所期望的结果：

SET ANSI_NULLS ON 
GO 
ALTER PROCEDURE [dbo].[sp_getSAPCMTX] 
    -- your code of the procedure 

创建本地属性和复制的值：

• SET ANSI_NULLS ON改变过程之前参数：
  
  

  ALTER PROCEDURE [dbo].[sp_getSAPCMTX] 
      @sSDate VARCHAR(10) 
      @sEDate VARCHAR(10) 
      @sBranch VARCHAR(4000) 
  AS 
  DECLARE @sDate VARCHAR(10) 
  DECLARE @eDate VARCHAR(10) 
  DECLARE @branch VARCHAR(4000) 
  
  SET @sDate = @sSDate 
  SET @eDate = @sEDate 
  SET @branch = @sBranch 
  
  -- your code of the procedure
