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

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();

其他回答

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();

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();

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)- > ();

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();
