使用DB :: raw和Eloquent使用同一查询的不同结果 [英] Different results using same query with DB::raw and Eloquent

问题描述

运行雄辩的联接查询时，我得到了一些意外的结果.通过使用完全相同的查询，我得到两个不同的结果.一个运行于DB :: raw()，第二个运行于Eloquent.

I'm getting some unexpected results when running an Eloquent join query. I get two different results from using the exact same query. One running with DB::raw(), the second with Eloquent.

在口才查询中，与

where squad_user.leave_time >= seasons.start_time

丢失，不会包含在结果集中.符合

are missing and will not be included in the result set. The users that matches the

or squad_user.leave is null

.

这是两个查询的结果之间的唯一区别.原始查询实际上会产生所需的结果集.

That's the only difference in the results from the two queries. The raw query actually produces the desired result set.

真的 使我感到困惑的是，如果我同时查询了Laravel和MySQL的查询日志，那么在同时运行raw和Eloquent查询时，我会得到完全相同的查询.

What really puzzles me is, if I check the query logs, both Laravel's and MySQL, I get the exact same query when running both the raw and Eloquent query.

原始查询(运行口才查询时从查询日志中获得的 actual 查询)

Raw query (the actual query i get from the query log when running the Eloquent query)

return \DB::select(\DB::raw('
        select users.*
        from users
        inner join squad_user on users.id = squad_user.user_id
        inner join seasons on squad_user.squad_id = seasons.squad_id
        where squad_user.join_time <= seasons.end_time
        and (squad_user.leave_time >= seasons.start_time or squad_user.leave_time is null)
        and seasons.id = :seasonId
    '),
    ['seasonId' => 3]
);

常用查询

return User::join('squad_user', 'users.id', '=', 'squad_user.user_id')
           ->join('seasons', 'squad_user.squad_id', '=', 'seasons.squad_id')
           ->where('squad_user.join_time', '<=', 'seasons.end_time')
           ->where(function ($query)
           {
               $query->where('squad_user.leave_time', '>=', 'seasons.start_time')
                     ->orWhereNull('squad_user.leave_time');
           })
           ->where('seasons.id', 3)
           ->get(['users.*']);

Laravel的口才查询日志

select `users`.*
from `users`
inner join `squad_user` on `users`.`id` = `squad_user`.`user_id`
inner join `seasons` on `squad_user`.`squad_id` = `seasons`.`squad_id`
where `squad_user`.`join_time` <= seasons.end_time
and (`squad_user`.`leave_time` >= seasons.start_time or `squad_user`.`leave_time` is null)
and `seasons`.`id` = 3
{"bindings":["seasons.end_time","seasons.start_time",3],"time":0.38,"name":"mysql"}

关于口才查询的MySQL的general_log

select `users`.*
from `users`
inner join `squad_user` on `users`.`id` = `squad_user`.`user_id`
inner join `seasons` on `squad_user`.`squad_id` = `seasons`.`squad_id`
where `squad_user`.`join_time` <= ?
and (`squad_user`.`leave_time` >= ? or `squad_user`.`leave_time` is null)
and `seasons`.`id` = ? 

关于Raw查询的MySQL的general_log

select users.*
            from users
            inner join squad_user on users.id = squad_user.user_id
            inner join seasons on squad_user.squad_id = seasons.squad_id
            where squad_user.join_time <= seasons.end_time
            and (squad_user.leave_time >= seasons.start_time or squad_user.leave_time is null)
            and seasons.id = ?

我会很感激此处，因为我很迷失.

I would appreciate any pointers here, as I am very lost.

推荐答案

where绑定第3个参数，通常将其视为字符串，除非您不通过使用raw语句告诉它. DB::raw或whereRaw将为您工作:

where binds 3rd param and treats it usually as a string, unless you tell it not to by using raw statement. DB::raw or whereRaw will work for you:

return User::join('squad_user', 'users.id', '=', 'squad_user.user_id')
       ->join('seasons', 'squad_user.squad_id', '=', 'seasons.squad_id')
       ->where('squad_user.join_time', '<=', DB::raw('seasons.end_time'))
       ->where(function ($query)
       {
           $query->where('squad_user.leave_time', '>=', DB::raw('seasons.start_time'))
                 ->orWhereNull('squad_user.leave_time');
       })
       ->where('seasons.id', 3)
       ->get(['users.*']);
