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?

代码示例。

首先:

$matchesLcl=[];

数组在这里被填充使用所需的计数/循环条件,增量:

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

更进一步,他又用了这样一种简洁的表达:

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'));

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');

使用这个

$users = DB::table('users')
                    ->where('votes', '>', 100)
                    ->orWhere('name', 'John')
                    ->get();

一定要对子查询应用任何其他过滤器,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();

你可以在几种情况下使用,

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

你也可以这样用,

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

你可以这样做,这是最短的方法。

    $results = User::where(['this'=>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])->get();
