如何使用 Laravel Eloquent 创建多个 Where 子句查询? [英] How to Create Multiple Where Clause Query Using Laravel Eloquent?

问题描述

我正在使用 Laravel Eloquent 查询构建器，并且我有一个查询，我希望在多个条件下使用 WHERE 子句.它有效，但并不优雅.

I'm using the Laravel Eloquent query builder and I have a query where I want a WHERE clause on multiple conditions. It works, but it's not elegant.

示例:

$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();

有没有更好的方法可以做到这一点，还是我应该坚持使用这种方法?

Is there a better way to do this, or should I stick with this method?

推荐答案

在 Laravel 5.3(从 7.x 开始仍然如此) 您可以使用更细粒度的 wheres 作为数组传递:

In Laravel 5.3 (and still true as of 7.x) you can use more granular wheres passed as an array:

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

就我个人而言，我还没有通过多次 where 调用找到这个用例，但事实是你可以使用它.

Personally I haven't found use-case for this over just multiple where calls, but fact is you can use it.

自 2014 年 6 月起，您可以将数组传递给 where

只要你想让所有的 wheres 使用 and 操作符，你就可以这样分组:

As long as you want all the wheres use and operator, you can group them this way:

$matchThese = ['field' => 'value', 'another_field' => 'another_value', ...];

// if you need another group of wheres as an alternative:
$orThose = ['yet_another_field' => 'yet_another_value', ...];

那么:

$results = User::where($matchThese)->get();

// with another group
$results = User::where($matchThese)
    ->orWhere($orThose)
    ->get();

以上将导致这样的查询:

The above will result in such query:

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