laravel具有:找不到列 [英] laravel having: Column not found

问题描述

我的以下代码是这样的:

my following code is like this:

$places = DivePlace::selectRaw("*,(st_distance_sphere( POINT(".$lon.",".$lat.") ,  point(lon, lat))/1000) as distance")
    ->havingRaw("distance < ".$radius)
    ->orderBy("distance")
    ->paginate(10);

没有"havingRaw"，一切都很好. 添加后，出现以下错误:

without the "havingRaw" everything is good. After adding it, the following error came up:

SQLSTATE [42S22]:找不到列:1054中的未知列'距离' '具有子句'(SQL:从dive_places中选择count(*)作为聚合 距离< 300)

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'distance' in 'having clause' (SQL: select count(*) as aggregate from dive_places having distance < 300)

有解决方案吗?

推荐答案

->where(DB::raw("(ST_Distance_Sphere(POINT(".$lon.",".$lat."), POINT(lon,lat))/1000)"), '<', 200)

而不是->havingRaw("(st_distance_sphere( POINT(?, ?) , point(lon, lat))/1000) < ?", [$lon, $lat, $radius])
