Question

我为报告创建了一个存储过程..

create Procedure [dbo].[sp_Score_Grade] 

@Month int,
@Year int,
@Log_User varchar(30)
AS
(
   SELECT Log_User, Count = COUNT(Det_Score), Score = SUM(Det_Score) 
   FROM MEMBER M,DETAILS D 
   WHERE D.Emp_Id = M.Emp_Id AND 
   Log_User like '@Log_User'
   AND Month(Sched_Start) = '@Month'
   AND Year(Sched_Start) = '@Year'
   GROUP BY Log_User
)

当出现Crystal Report对话框询问参数时，我会检查所有值为null。但在我继续下一步之前。显示以下错误。

Database Connector Error:
Source: Microsoft OLE DB Provider for SQL Server
Description: Conversion failed when converting the varchar value '@Month' to data type int
SQL State: 22018
Native Error: 245[Database Vendor Code: 245]

我希望有人在这里向我解释为什么我会收到这个错误，我该怎么办... 我正在使用MS SQL Server 2005和Crystal Report for VS2010 ..

提前谢谢。：d

Answer 1

您的参数名称在查询中分隔，因此SQL Server将它们视为文字字符串。尝试

Log_User like @Log_User
   AND Month(Sched_Start) = @Month
   AND Year(Sched_Start) = @Year

数据库连接错误
