Question

我对laravel很新，但实际上我在基本的工作人员中得到了错误的结果，我很困惑。

我有一张桌子：

Schema::create('matches', function(Blueprint $table)
    {
        $table->increments('id')->unsigned()->index();
        $table->integer('season_id')->unsigned()->index();
        $table->foreign('season_id')
            ->references('id')
            ->on('seasons')
            ->onUpdate('cascade')
            ->onDelete('cascade')
        ;
        $table->integer('championship_id')->unsigned()->index();
        $table->foreign('championship_id')
            ->references('id')
            ->on('championships')
            ->onUpdate('cascade')
            ->onDelete('cascade')
        ;
        $table->integer('round')->unsigned()->index();
        $table->integer('match')->unsigned()->index();

        $table->integer('team1_id')->unsigned()->index();
        $table->foreign('team1_id')
            ->references('id')
            ->on('teams')
            ->onUpdate('cascade')
            ->onDelete('cascade')
        ;
        $table->integer('team2_id')->unsigned()->index();
        $table->foreign('team2_id')
            ->references('id')
            ->on('teams')
            ->onUpdate('cascade')
            ->onDelete('cascade')
        ;

        $table->integer('team1_goals')->unsigned()->nullable()->default(null);
        $table->integer('team2_goals')->unsigned()->nullable()->default(null);
        $table->integer('team1_misses')->unsigned()->nullable()->default(null);
        $table->integer('team2_misses')->unsigned()->nullable()->default(null);
        $table->timestamp('start_at');
        $table->boolean('finished')->default(0);
        $table->timestamps();
    });

经过一些数学计算后，它充满了团队ID，目标，未命中等的价值观。好的，现在我想获得team1获胜的所有原始数据，（team1_goals＆gt; team2_goals）

在工匠修补匠中输入：

$matches = App\Match::where('team1_goals','>','team2_goals')->get()

并得到如此意外的结果（最后4个）：

<App\Match #00000000455ad9a2000000015b65c7f8> {
       id: 237,
       season_id: 1,
       championship_id: 1,
       round: 30,
       match: 5,
       team1_id: 7,
       team2_id: 10,
       team1_goals: 2,
       team2_goals: 1,
       team1_misses: 2,
       team2_misses: 2,
       start_at: "2015-06-21 14:38:22",
       finished: 1,
       created_at: "2015-06-21 13:53:52",
       updated_at: "2015-06-21 13:57:00"
   },
   <App\Match #00000000455ad9dd000000015b65c7f8> {
       id: 238,
       season_id: 1,
       championship_id: 1,
       round: 30,
       match: 6,
       team1_id: 9,
       team2_id: 12,
       team1_goals: 2,
       team2_goals: 2,
       team1_misses: 1,
       team2_misses: 1,
       start_at: "2015-06-21 14:38:22",
       finished: 1,
       created_at: "2015-06-21 13:53:52",
       updated_at: "2015-06-21 13:57:00"
   },
   <App\Match #00000000455ad9dc000000015b65c7f8> {
       id: 239,
       season_id: 1,
       championship_id: 1,
       round: 30,
       match: 7,
       team1_id: 5,
       team2_id: 16,
       team1_goals: 1,
       team2_goals: 3,
       team1_misses: 0,
       team2_misses: 0,
       start_at: "2015-06-21 14:38:22",
       finished: 1,
       created_at: "2015-06-21 13:53:52",
       updated_at: "2015-06-21 13:57:00"
   },
   <App\Match #00000000455ad9df000000015b65c7f8> {
       id: 240,
       season_id: 1,
       championship_id: 1,
       round: 30,
       match: 8,
       team1_id: 8,
       team2_id: 1,
       team1_goals: 1,
       team2_goals: 2,
       team1_misses: 1,
       team2_misses: 1,
       start_at: "2015-06-21 14:38:22",
       finished: 1,
       created_at: "2015-06-21 13:53:52",
       updated_at: "2015-06-21 13:57:00"
   }

如你所见：

id 237：team1_goals＆gt; team2_goals
id 238：team1_goals = team2_goals，
id 239：team1_goals＆lt; team2_goals，
id 240：team1_goals＆lt; team2_goals，

$ matches = App \ Match :: where（'team1_goals'，'＆gt;'，'team2_goals'） - ＆gt; count（）

给出结果222（240）所以它不是全部（）或smth

为什么会发生这种情况？

Answer 1

看起来像得到它：在哪里函数3rd参数不能设置为字段名称，所以我的案例比较就像

select * from matches where team1_goals > 'team2_goals'

我应该使用

$matches = App\Match::whereRaw('team1_goals > team2_goals')->get();

Laravel：使用model :: where获得错误的结果
