SQL存储过程的模糊查询问题
SET ANSI_NULLS ON

IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[Pr_Name_GetDocuments]') AND type in (N'P', N'PC'))
BEGIN
EXEC dbo.sp_executesql @statement = N'CREATE PROCEDURE [dbo].[Pr_Name_GetDocuments]
(
@Title varchar(50)
)
AS

SELECT
  Document.*,Staff.RealName

FROM  
  Document ,Staff
WHERE  
  Staff.Staff_ID = Document.UserID and Document.Title like '%'+@Title+'%'
 
' 
END



这样写怎么一直提示'%' 附近有语法错误。。。菜鸟求教大神啊。。。

[解决办法]

SQL code

exec('SELECT  Document.*,Staff.RealNameFROM     Document ,StaffWHERE     Staff.Staff_ID = Document.UserID and charindex('+@title+'Document.Title)>0') 改成这样
[解决办法]
Staff.Staff_ID = Document.UserID and Document.Title like ''%''+@Title+''%''
