Question

我已经创建了这个存储过程，这可能有点长但是它可以工作。但是，我使用实体框架来完成这个项目。但是当它运行时它给了我这个错误：

未处理的类型异常   ＆＃39; System.Data.EntityCommandExecutionException＆＃39;发生在   System.Data.Entity.dll

其他信息：数据阅读器与。不兼容   指定＆＃39; SchoolsModel.TeacherClassesSorting_Result＆＃39;。一个成员   类型，＆＃39; ClassID＆＃39;，在数据中没有对应的列   读者同名。

这是我在SQL Server中创建的SP：

ALTER PROCEDURE [dbo].[TeacherClassesSorting] 
@ID int,
@sub int,
@frm int,
@trm int,
@yr nvarchar(15)

BEGIN

BEGIN

              inner join Subjects as sub on sub.SubjectCode = c.SubjectCode

我是编程新手，所以请耐心等待，我并不完美。谁能帮我。谢谢！
