SQL2008 存储过程参数相关

 

 使用inputparame时，使用的是 varchar(20)，和数据库中的DEPARTNAME完全匹配，可以查出值：

USE [test]
GO

SET ANSI_NULLS OFF
GO

SET QUOTED_IDENTIFIER OFF
GO


ALTER PROCEDURE [dbo].[pro_testprocedure](@inputparame varchar(20))
    
AS

BEGIN
    SELECT DEPARTNAME, charindex( @inputparame, DEPARTNAME) as indexNo
    from his_depart
END
GO

 而使用inputparame时，使用的是 varchar时，却没用能够用过varindex得到值：

USE [test]
GO

SET ANSI_NULLS OFF
GO

SET QUOTED_IDENTIFIER OFF
GO


ALTER PROCEDURE [dbo].[pro_testprocedure](@inputparame varchar)
    
AS

BEGIN
    SELECT DEPARTNAME, charindex( @inputparame, DEPARTNAME) as indexNo
    from his_depart
END
GO
