我使用Laravel雄辩的查询构建器,我有一个查询,我想在多个条件上有一个where子句。它能起作用,但并不优雅。

例子:

$results = User::where('this', '=', 1)
    ->where('that', '=', 1)
    ->where('this_too', '=', 1)
    ->where('that_too', '=', 1)
    ->where('this_as_well', '=', 1)
    ->where('that_as_well', '=', 1)
    ->where('this_one_too', '=', 1)
    ->where('that_one_too', '=', 1)
    ->where('this_one_as_well', '=', 1)
    ->where('that_one_as_well', '=', 1)
    ->get();

有没有更好的方法,或者我应该坚持这个方法?


当前回答

如果你的条件是这样的(匹配一个值),一个简单的更优雅的方式是:

$results = User::where([
         'this' => value,
         'that' => value,
         'this_too' => value,
          ...
      ])
    ->get();

但如果你需要OR子句,那么确保你对每个OR where()子句重复必须满足条件。

    $player = Player::where([
            'name' => $name,
            'team_id' => $team_id
        ])
        ->orWhere([
            ['nickname', $nickname],
            ['team_id', $team_id]
        ])

其他回答

使用Array的条件:

$users = User::where([
       'column1' => value1,
       'column2' => value2,
       'column3' => value3
])->get();

将产生如下查询:

SELECT * FROM TABLE WHERE column1 = value1 and column2 = value2 and column3 = value3

使用匿名函数的条件:

$users = User::where('column1', '=', value1)
               ->where(function($query) use ($variable1,$variable2){
                    $query->where('column2','=',$variable1)
                   ->orWhere('column3','=',$variable2);
               })
              ->where(function($query2) use ($variable1,$variable2){
                    $query2->where('column4','=',$variable1)
                   ->where('column5','=',$variable2);
              })->get();

将产生如下查询:

SELECT * FROM TABLE WHERE column1 = value1 and (column2 = value2 or column3 = value3) and (column4 = value4 and column5 = value5)

在Laravel 5.3中(在7.x中仍然如此),你可以使用更细粒度的数组:

$query->where([
    ['column_1', '=', 'value_1'],
    ['column_2', '<>', 'value_2'],
    [COLUMN, OPERATOR, VALUE],
    ...
])

就我个人而言,我还没有发现这个用例超过多个where调用,但事实是你可以使用它。

自2014年6月起,您可以将数组传递到where

只要你想要所有的where use和operator,你可以这样分组:

$matchThese = ['field' => 'value', 'another_field' => 'another_value', ...];

// if you need another group of wheres as an alternative:
$orThose = ['yet_another_field' => 'yet_another_value', ...];

然后:

$results = User::where($matchThese)->get();

// with another group
$results = User::where($matchThese)
    ->orWhere($orThose)
    ->get();

以上将导致这样的查询:

SELECT * FROM users
  WHERE (field = value AND another_field = another_value AND ...)
  OR (yet_another_field = yet_another_value AND ...)

在Eloquent中,你可以这样做:

$results = User::where('this', '=', 1)
->orWhere('that', '=', 1)
->orWhere('this_too', '=', 1)
->orWhere('that_too', '=', 1)
->orWhere('this_as_well', '=', 1)
->orWhere('that_as_well', '=', 1)
->orWhere('this_one_too', '=', 1)
->orWhere('that_one_too', '=', 1)
->orWhere('this_one_as_well', '=', 1)
->orWhere('that_one_as_well', '=', 1)
->get();

你可以在Laravel 5.3中使用eloquent

所有的结果

UserModel::where('id_user', $id_user)
                ->where('estado', 1)
                ->get();

部分结果

UserModel::where('id_user', $id_user)
                    ->where('estado', 1)
                    ->pluck('id_rol');

使用纯Eloquent,像这样实现它。这段代码返回所有帐户处于活动状态的已登录用户。 $用户= \ App \用户::(“状态”,“积极”)——> (logged_in,真的)- > ();
