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

您可以在where子句中使用数组,如下所示。

$result=DB::table('users')->where(array(
'column1' => value1,
'column2' => value2,
'column3' => value3))
->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);
    }

终于得到了结果

    $result = $query->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'));

在Laravel 5.3中(在7.x中仍然如此),你可以使用更细粒度的数组:

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

就我个人而言,我还没有发现这个用例超过多个where调用,但事实是你可以使用它。

自2014年6月起,您可以将数组传递到where

只要你想要所有的where use和operator,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 ...)

使用Eloquent很容易创建多个where检查:

首先:(使用简单的where)

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

第二个:(在数组中分组where)

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

你也可以在里面使用条件(=,<>,等等),就像这样:

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