将查询转换为实体框架.net

Question

以下查询在SQL Server中正常运行。

但是如何将其转换为实体框架？

Select * 
from Gp 
where Teacher_id IN (SELECT Teacher_Id
                     FROM TW
                     group by Teacher_Id
                     having sum(Credit_Total)  >= 15)

Answer 1

这样的事情对你有用：

var result = 
from g in Gp
    from teacher in TW
        group teacher by teacher.Teacher_Id into goupedTeachers
        where goupedTeachers.Sum(t=>t.Credit_Total) >= 15
where g.Teacher_id == groupedTeachers.Key
select g;
