如何使用Laravel Eloquent创build多个where子句查询?

我正在使用Laravel雄辩查询生成器,我有查询,我想在多个东西的WHERE子句。 它工作,但不是优雅的。

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,还是应该坚持这个方法?

在Laravel 5.3中 ,可以使用更多粒度的数组:

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

就个人而言,我还没有find用于此的多用途的where ,但事实是您可以使用它。

自2014年6月以来,您可以将数组传递到where

只要你想要所有的使用者and操作者,你可以这样分组他们:

 $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:

在你的模型中,像这样创build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build查询时调用这个范围:

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

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

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'); }); 

它应该为您提供一个像这样的查询:

 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') 

多个子句的地方

  $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); } 

最后得到结果

  $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运算符进行连接。

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(); 

有关更多信息,请查阅https://laravel.com/docs/5.4/queries#where-clauses文档的这一部分;

使用Array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Antonymous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) 

没有一个真实的例子,很难提出build议。 但是,我从来不需要在查询中使用这么多的WHERE子句,这可能表明数据结构有问题。

了解数据标准化可能会对您有所帮助: http : //en.wikipedia.org/wiki/Third_normal_form

确保将其他筛选器应用于子查询,否则可能会收集所有logging。

 $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(); 

你可以在Laravel 5.3中使用雄辩

所有结果

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

部分结果

 UserModel::where('id_user', $id_user) ->where('estado', 1) ->pluck('id_rol'); 
 public function search() { if (isset($_GET) && !empty($_GET)) { $prepareQuery = ''; foreach ($_GET as $key => $data) { if ($data) { $prepareQuery.=$key . ' = "' . $data . '" OR '; } } $query = substr($prepareQuery, 0, -3); if ($query) $model = Businesses::whereRaw($query)->get(); else $model = Businesses::get(); return view('pages.search', compact('model', 'model')); } } 

只是添加或第四参数。 例如:

 $results = User::where('this', '=', 1) ->where('that', '=', 1, 'OR') ->where('this_too', '=', 1, 'OR') ->where('that_too', '=', 1, 'OR') ->where('this_as_well', '=', 1, 'OR') ->where('that_as_well', '=', 1, 'OR') ->where('this_one_too', '=', 1, 'OR') ->where('that_one_too', '=', 1, 'OR') ->where('this_one_as_well', '=', 1, 'OR') ->where('that_one_as_well', '=', 1, 'OR') ->get(); 
 $variable = array('this' => 1, 'that' => 1 'that' => 1, 'this_too' => 1, 'that_too' => 1, 'this_as_well' => 1, 'that_as_well' => 1, 'this_one_too' => 1, 'that_one_too' => 1, 'this_one_as_well' => 1, 'that_one_as_well' => 1); foreach ($variable as $key => $value) { User::where($key, '=', $value); }
