我编写了以下生成报告的 sql。我运行一些 sql sueries 并将它们的结果存储在临时表中，并在存储过程结束时将所有表合并在一起。但是，当我将此存储过程添加到 EF 时，它不会为它创建一个复杂的类型，没有它就没有用。如何让 EF 识别返回的结果集并创建复杂类型。

@profileID AS INT,
@organisationID as INT,
@startDate as date,
@endDate as date

EF 不会为您创建复杂类型，但 EF 可以实例化声明复杂类型的对象集合。

例如

public class AType {
     public String Prop1 {get; set;}
}

context.Database.SqlQuery<AType>("select c1 as Prop1 from ATable");

将返回AType. 如果您将查询替换为对存储过程的调用，则相同。

在你的情况下，你必须声明一个类型来映射你的存储过程的返回。

否则，您可能会环顾四周，但：

  • 不知道EF能不能用
  • 您将失去使用编译语言的优势。

经过一些动态测试后，返回了正确的数字或​​对象，但我对它们无能为力。
