我的以下代码是这样的:
$places = DivePlace::selectRaw("*,(st_distance_sphere( POINT(".$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:
SQLSTATE [42S22]:未找到列:1054未知列“距离” 'having clause'(SQL:从
dive_places
选择count(*)作为聚合 距离&lt; 300)
任何解决方案?
答案 0 :(得分:2)
->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])
答案 1 :(得分:0)
您需要重复距离定义,因为对于分页,Laravel仅对列使用count(*)
,因此它应该是:
$places = DivePlace::selectRaw("*,(st_distance_sphere( POINT(".$lon.",".$lat.") , point(lon, lat))/1000) as distance")
->havingRaw("(st_distance_sphere( POINT(".$lon.",".$lat.") , point(lon, lat))/1000) < ".$radius)
->orderBy("distance")
->paginate(10);
您也可以对查询使用绑定,因此最好是:
$places = DivePlace::selectRaw("*,(st_distance_sphere( POINT(?, ?) , point(lon, lat))/1000) as distance",[$lon, $lat])
->havingRaw("(st_distance_sphere( POINT(?, ?) , point(lon, lat))/1000) < ?", [$lon, $lat, $radius])
->orderBy("distance")
->paginate(10);
