实体框架和MySQL无法插入

Question

我试图插入行MySQL数据库和我得到这个错误。

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(SELECT 
`groups_users`.`groupID`, 
`groups_u' at line 1 

守则是

 groups_users ug = new groups_users(); 
     ug.groupID = 1; 
     ug.userID = 1; 
     ug.isDeleted = false; 
     ug.created = DateTime.Now; 
     ctx.groups_users.Add(ug); 

     ctx.SaveChanges(); 

感谢

固定它。 在edmx文件中有问题。所有字段都被设置为实体键。
