Laravel :query select 'as' 不使用 where 或 have

Question

我正在尝试联系附近的公司这是我的查询

$lat = 21.41241750000001;
$long = 39.23094140625001;
return
    $this->model->select('id', 'lat', 'long', DB::raw(sprintf(
    '(6371 * acos(cos(radians(%1$.7f)) * cos(radians(`lat`)) * cos(radians(`long`) - radians(%2$.7f)) + sin(radians(%1$.7f)) * sin(radians(`lat`)))) AS `distance`',
    $lat,
    $long
)))
    ->having('distance', '<', 50)
    ->orderBy('distance', 'asc')
    ->paginate();

总是得到我

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'distance' in 'having clause' (SQL: select count(*) as aggregate from companies having distance = 50)

我的 table 架构

注意：如果我在没有 have 的情况下进行查询并订购返回和计算的距离有帮助吗？

Answer 1

我遇到了类似的问题。我根据您的上下文调整了我的代码。您可以尝试添加选择。我认为这段代码是您解决方案的起点：

$lat = 21.41241750000001;
$long = 39.23094140625001;
Companies::addSelect(['distance' => DB::raw(sprintf('(6371 * acos(cos(radians(%1$.7f)) * cos(radians(`lat`)) * cos(radians(`long`) - radians(%2$.7f)) + sin(radians(%1$.7f)) * sin(radians(`lat`)))) AS `distance`',
                      $lat,
                      $long))
                      ])                    
          ->havingRaw('distance < 50')
          ->orderBy('distance', 'asc')
          ->get();

我无法测试它；向我们发送反馈！
