如何使用Laravel Eloquent创建多个Where子句查询？

Question

我正在使用Laravel Eloquent查询构建器,我有一个查询,我希望WHERE在多个条件下有一个子句.它有效,但它并不优雅.

例:

$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？

Answer 1

在Laravel 5.3中,您可以使用更多粒度的数组作为数组传递:

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

就个人而言,我没有在多次where通话中找到用例,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wheres使用and操作符,你就可以这样对它们进行分组:

$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();

以上将导致此类查询:

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

Answer 2

查询范围可以帮助您使代码更具可读性.

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

用一些例子更新这个答案:

在您的模型中,创建这样的范围方法:

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();

Answer 3

您可以在匿名函数中使用子查询,如下所示:

 $results = User::where('this', '=', 1)
            ->where('that', '=', 1)
            ->where(function($query) {
                /** @var $query Illuminate\Database\Query\Builder  */
                return $query->where('this_too', 'LIKE', '%fake%')
                    ->orWhere('that_too', '=', 1);
            })
            ->get();

Answer 4

在这种情况下,你可以使用这样的东西:

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')

Answer 5

使用数组的条件:

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

会产生如下的查询:

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

使用反义函数的条件:

$users = User::where('column1', '=', value1)
               ->where(function($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();

会产生如下的查询:

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

Answer 6

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);
    }

终于得到了结果

    $result = $query->get();

Answer 7

该whereColumn方法可以传递多个条件的数组.这些条件将使用and运营商加入.

例:

$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();

Answer 8

多个地点

• 您还可以将条件数组传递给 where 函数。数组的每个元素应该是一个包含通常传递给 where 方法的三个参数的数组：

Model::where([
    ['status', '=', '1'],
    ['subscribed', '<>', '1'],
])->get();

多个或Where子句

• 如果需要将“or”条件分组在括号内，则可以将闭包作为第一个参数传递给 orWhere 方法：

Model::where('votes', '>', 100)
        ->orWhere(function ($query) {
            $query->where('name', 'abcd')
                ->orWhere(function ($query) {
                    $query->where('name', 'cdef')
                        ->where('votes', '>', 50);
                });
        })
        ->get();

上面的示例将生成以下 SQL：

select * from `users` where `votes` > 100 or (`name` = "abcd" or (`name` = "cdef" and `votes` > 50));

带有 whereNot 和 orWhereNot 方法的相互 where

• whereNot 和 orWhereNot 方法可用于否定给定的一组查询约束。例如，以下查询排除正在清仓或价格低于 10 的产品：

$products = Product::where([
        ['status', '=', '1'],
        ['is_feature', '1']
    ])
        ->whereNot(function ($query) {
            $query->where('clearance', true)
                ->orWhere('price', '<', 10);
        })
        ->get();

Answer 9

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

要么

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

要么

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

Answer 10

确保将任何其他过滤器应用于子查询,否则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();

Answer 11

$projects = DB::table('projects')->where([['title','like','%'.$input.'%'],
    ['status','<>','Pending'],
    ['status','<>','Not Available']])
->orwhere([['owner', 'like', '%'.$input.'%'],
    ['status','<>','Pending'],
    ['status','<>','Not Available']])->get();

Answer 12

使用 Eloquent 可以轻松创建多个 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：（将你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 where 内使用条件（=、<> 等），如下所示：

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