，写了个存储过程，调用的时候出有关问题了

求助，写了个存储过程，调用的时候出问题了？
写了个存储过程，调用的时候，老是提示存储过程名字附近有错误，各位大侠来帮我看看
create proc MTU

@MTLastMark nvarchar(50),
@MTMarkup nvarchar(50),
@MTNumber nvarchar(120),
@ID nvarchar(120),
@Coures nvarchar(50)
as

begin


insert into MakeupTest(MTNumber,MTName,MTClass,MTCourseID,MTCourse,MTCharacter,MTTestWay,MTCredit,MTLastMark,MTMarkup,MTGeneral,MTTeacherID,MTTeacher,MTDepartment,MTInstitute,MTFailYear,MTFailTerm,MGrade,MTArea) 
select MTNumber,MTName,MTClass,MTCourseID,MTCourse,MTCharacter,MTTestWay,MTCredit,MTLastMark,MTMarkup,MTGeneral,MTTeacherID,MTTeacher,MTDepartment,MTInstitute,MTFailYear,MTFailTerm,MGrade,MTArea from MakeupTest 
where MTNumber= @MTNumber and MTTeacherID=@ID and MTCourse=@Coures


update MakeupTest set MTLastMark=@MTLastMark,MTMarkup=@MTMarkup 
where MTNumber= @MTNumber and MTTeacherID=@ID and MTCourse=@Coures and MRetest is null

end

你是怎么调用的
[解决办法]
貌似上面那种传参的写法是你们自己写的方法吧？

[解决办法]
先在查询分析器.运行存储过程看看
 

SQL code

MTU 'test','test','test','test','test'
[解决办法]
是:成功就是C#代码问题了 ..
