How to write raw query in Laravel? - laravel

Question

There is a query:
SELECT ST_DistanceSpheroid(geometry(location), ST_GeomFromText('POINT(37.854289 55.685333)'), 'SPHEROID["WGS 84",6378137,298.257223563]')
FROM users
How to pass parameter 37.854289 55.685333?
Also I tried this:
$point = "37.854289 55.685333";
return DB::table('users')
->select(DB::raw('ST_DistanceSpheroid(geometry(location), ST_GeomFromText(\'POINT(?)\'), \'SPHEROID["WGS 84",6378137,298.257223563]\''), [$point])
->get();
I got this error:
"message": "stripos(): Argument #1 ($haystack) must be of type string, array given",
My attempt bases accepted question:
$lon = 37.857397;
$lat = 55.685333;
return DB::table('users')
->selectRaw(
"(ST_DistanceSpheroid(
geometry(location),
ST_GeomFromText('POINT(? ?)'),
'SPHEROID[?, ?, ?]'
)) as distance",
[$lon, $lat, 'WGS 84', 6378137, 298.257223563]
)->leftJoin('doctors', 'doctors.user_id', 'users.id')->orderBy('distance', 'ASC')->get();
I have got an error:
{
"message": "PDO: SQLSTATE[XX000]: Internal error: 7 ОШИБКА: SPHEROID parser - couldnt parse the spheroid\nLINE 4: 'SPHEROID[?, ?, ?]'\n ^ (SQL: select (ST_DistanceSpheroid(\n geometry(location),\n ST_GeomFromText('POINT(37.857397 55.685333)'),\n 'SPHEROID[WGS 84, 6378137, 298.257223563]'\n )) as distance from \"users\" left join \"doctors\" on \"doctors\".\"user_id\" = \"users\".\"id\" order by \"distance\" asc)"
}
The row query that works:
SELECT doctors.user_id, (ST_DistanceSpheroid(geometry(location), ST_GeomFromText('POINT(37.857397 55.690576)'), 'SPHEROID["WGS 84",6378137,298.257223563]')
) as distance FROM users INNER JOIN doctors ON doctors.user_id = users.id ORDER BY distance ASC

You almost got it. The [$point] parameter should be the second parameter of DB::raw($query, $bindings) but you added it as a second parameter to select().
// What you have
->select(DB::raw(...), [$point])
// correct syntax
->select(DB::raw(..., [$point]))
If you've got nothing else to put in your select clause, might as well use selectRaw(). It's the same as select(DB::raw()).
DB::table('users')
->selectRaw('ST_DistanceSpheroid(geometry(location), ST_GeomFromText(\'POINT(?)\'), \'SPHEROID["WGS 84",6378137,298.257223563]\')', [$point])
Personally, I'd write the query like this:
$query = DB::table('users')
->selectRaw(
"ST_DistanceSpheroid(
geometry(location),
ST_GeomFromText('POINT(? ?)'),
'SPHEROID[?, ?, ?]'
)",
[37.854289, 55.685333, 'WGS 84', 6378137, 298.257223563]
)
->get();
