我正在使用 Laravel Eloquent 查询构建器,并且我有一个查询,我想要一个WHERE关于多个条件的子句。它有效,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();

有没有更好的方法来做到这一点,还是我应该坚持这种方法?

Laravel 5.3中(在7.x中仍然如此),您可以使用更细粒度的 wheres 作为数组传递:

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

就我个人而言,我还没有通过多次调用找到这个用例where,但事实是你可以使用它。

自 2014 年 6 月起,您可以将数组传递给where

只要你想要所有的wheresuseand运算符,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 ...)

查询范围可以帮助您让您的代码更具可读性。

http://laravel.com/docs/eloquent#query-scopes

用一些例子更新这个答案:

在您的模型中,创建如下范围方法:

public function scopeActive($query)
{
    return $query->where('active', '=', 1);
}

public function scopeThat($query)
{
    return $query->where('that', '=', 1);
}

然后,您可以在构建查询时调用此范围:

$users = User::active()->that()->get();

您可以像这样在匿名函数中使用子查询:

 $results = User::where('this', '=', 1)
       ->where('that', '=', 1)
       ->where(
           function($query) {
             return $query
                    ->where('this_too', 'LIKE', '%fake%')
                    ->orWhere('that_too', '=', 1);
            })
            ->get();

在这种情况下,您可以使用以下内容:

User::where('this', '=', 1)
    ->whereNotNull('created_at')
    ->whereNotNull('updated_at')
    ->where(function($query){
        return $query
        ->whereNull('alias')
        ->orWhere('alias', '=', 'admin');
    });

它应该为您提供如下查询:

SELECT * FROM `user` 
WHERE `user`.`this` = 1 
    AND `user`.`created_at` IS NOT NULL 
    AND `user`.`updated_at` IS NOT NULL 
    AND (`alias` IS NULL OR `alias` = 'admin')

使用数组的条件:

$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)

Model::where('column_1','=','value_1')
       ->where('column_2 ','=','value_2')
       ->get();

或者

// If you are looking for equal value then no need to add =
Model::where('column_1','value_1')
        ->where('column_2','value_2')
         ->get();

或者

Model::where(['column_1' => 'value_1',
              'column_2' => 'value_2'])->get();

多个 where 子句

    $query=DB::table('users')
        ->whereRaw("users.id BETWEEN 1003 AND 1004")
        ->whereNotIn('users.id', [1005,1006,1007])
        ->whereIn('users.id',  [1008,1009,1010]);
    $query->where(function($query2) use ($value)
    {
        $query2->where('user_type', 2)
            ->orWhere('value', $value);
    });

   if ($user == 'admin'){
        $query->where('users.user_name', $user);
    }

终于得到结果

    $result = $query->get();

whereColumn方法可以传递多个条件的数组。这些条件将使用and运算符连接起来。

例子:

$users = DB::table('users')
            ->whereColumn([
                ['first_name', '=', 'last_name'],
                ['updated_at', '>', 'created_at']
            ])->get();

$users = User::whereColumn([
                ['first_name', '=', 'last_name'],
                ['updated_at', '>', 'created_at']
            ])->get();

请务必将任何其他过滤器应用于子查询,否则 or 可能会收集所有记录。

$query = Activity::whereNotNull('id');
$count = 0;
foreach ($this->Reporter()->get() as $service) {
        $condition = ($count == 0) ? "where" : "orWhere";
        $query->$condition(function ($query) use ($service) {
            $query->where('branch_id', '=', $service->branch_id)
                  ->where('activity_type_id', '=', $service->activity_type_id)
                  ->whereBetween('activity_date_time', [$this->start_date, $this->end_date]);
        });
    $count++;
}
return $query->get();

使用 Eloquent 可以很容易地创建多个 where 检查:

第一:(使用简单的where)

$users = User::where('name', $request['name'])
    ->where('surname', $request['surname'])
    ->where('address', $request['address'])
    ...
    ->get();

第二:(将您的位置分组到数组中)

$users = User::where([
    ['name', $request['name']],
    ['surname', $request['surname']],
    ['address', $request['address']],
    ...
])->get();

您还可以在其中使用条件(=、<> 等),如下所示:

$users = User::where('name', '=', $request['name'])
    ->where('surname', '=', $request['surname'])
    ->where('address', '<>', $request['address'])
    ...
    ->get();

您可以通过多种方式使用,

$results = User::where([
    ['column_name1', '=', $value1],
    ['column_name2', '<', $value2],
    ['column_name3', '>', $value3]
])->get();

你也可以这样使用,

$results = User::orderBy('id','DESC');
$results = $results->where('column1','=', $value1);
$results = $results->where('column2','<',  $value2);
$results = $results->where('column3','>',  $value3);
$results = $results->get();

你可以在Laravel 5.3中使用 eloquent

所有结果

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');

根据我的建议,如果您正在进行过滤或搜索

那么你应该去:

        $results = User::query();
        $results->when($request->that, function ($q) use ($request) {
            $q->where('that', $request->that);
        });
        $results->when($request->this, function ($q) use ($request) {
            $q->where('this', $request->that);
        });
        $results->when($request->this_too, function ($q) use ($request) {
            $q->where('this_too', $request->that);
        });
        $results->get();

代码示例。

首先 :

$matchesLcl=[];

使用所需的条件计数/循环在此处填充数组,增量:

 $matchesLcl['pos']= $request->pos;
$matchesLcl['operation']= $operation;
//+......+
$matchesLcl['somethingN']= $valueN;

并进一步使用像这种收缩表达这样的雄辩:

if (!empty($matchesLcl))
    $setLcl= MyModel::select(['a', 'b', 'c', 'd'])
        ->where($matchesLcl)
        ->whereBetween('updated_at', array($newStartDate . ' 00:00:00', $newEndDate . ' 23:59:59'));
else 
    $setLcl= MyModel::select(['a', 'b', 'c', 'd'])
        ->whereBetween('updated_at', array($newStartDate . ' 00:00:00', $newEndDate . ' 23:59:59'));

您可以在 where 子句中使用数组,如下所示。

'column1' => value1,
'column2' => value2,
'column3' => value3))
->get();

如果你的条件是这样的(匹配单个值),一个简单更优雅的方法是:

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

但是如果您需要 OR 子句,请确保为每个 orWhere() 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]
        ])

我们使用该指令根据用户分类类型和用户名两个条件获取用户。

在这里,除了从配置文件表中获取用户信息以减少查询数量外,我们还使用两个条件在您键入时进行过滤。

$users = $this->user->where([
                    ['name','LIKE','%'.$request->name.'%'],
                    ['trainers_id','=',$request->trainers_id]
