C# >；类型'；ClassID'；，数据中没有相应的列>；同名读取器

我创建了这个存储过程，它可能有点长，但仍然可以工作。然而，我正在使用实体框架来完成这个项目。但是，当它运行时，会出现以下错误：

类型的未处理异常 中发生“System.Data.EntityCommandExecutionException” System.Data.Entity.dll

附加信息：数据读取器与 指定的“SchoolsModel.TeacherClasseSorting_结果”。委员会成员 类型“ClassID”在数据中没有相应的列 具有相同名称的读取器

以下是我在SQL Server中创建的SP：

@sub int,

我是编程新手，所以请容忍我，我在这方面并不完美。有人能帮我吗。谢谢

添加从中获取错误的代码行。也许可以在存储过程中添加一条select语句，如果所有参数都为NULL（即默认值），则该语句将运行—如果trm为NULL，frm为NULL，sub为NULL，yr为NULL，ID为NULL，则在上面的代码段中，您所述的@Brendan有一条select语句
