Question

我有一个LINQ查询使用连接，我没有足够的LINQ知识我想在SQL中转换此查询请帮助我谢谢。在我发布LINQ查询的代码中，请帮我在sql中转换这个查询。

var secUserList = (from secUser in dc.sec_users
                   join userRoles in dc.sec_user_roles
                   on secUser.user_id equals userRoles.user_id
                   join secUserAuth in dc.sec_user_authentications
                   on secUser.user_id equals secUserAuth.user_id
                   where userRoles.role_id == roleId
                   orderby secUser.first_name
                   select new { secUser, secUserAuth });

这是非常直接的，不是吗？

SELECT secUser.*, secUserAuth.*  
FROM sec_users secUser
INNER JOIN sec_user_roles userRoles
   ON secUser.user_id = userRoles.user_id
INNER JOIN sec_user_authentications secUserAuth
   ON secUser.user_id = secUserAuth.user_id
WHERE userRoles.role_id = roleId
ORDER BY secUser.first_name

如何将LINQ查询转换为SQL？
