This is the function that is executing the query:
public static function getNearbyCityReport(float $lon, float $lat, float $rangeInKm){
$query = "
SELECT
name,
population,
round((ST_Distance(rpoint, 'POINT( ? ? )', True)/1000)::numeric, 1) as distance,
round(degrees(ST_Azimuth(rpoint, 'POINT( ? ? )'))::numeric,1) AS azimuth
FROM
gis_cities
WHERE
ST_DWithin(rpoint, 'POINT( ? ? )', 1000*?, True)
AND
feature_code != 'PPLX'
ORDER BY distance;
";
$query = preg_replace('#\n#', ' ', $query);
$query = trim(preg_replace('#\s{2,}#', ' ', $query));
$expression = DB::raw($query);
$result = DB::select($expression, [$lon, $lat, $lon, $lat, $lon, $lat, $rangeInKm]);
dd($result);
When running this function I get the following exception:
SQLSTATE[HY093]: Invalid parameter number: parameter was not defined (SQL: SELECT name, population, round((ST_Distance(rpoint, 'POINT( 24.8 43.3648 )', True)/1000)::numeric, 1) as distance, round(degrees(ST_Azimuth(rpoint, 'POINT( 24.8 43.3648 )'))::numeric,1) AS azimuth FROM gis_cities WHERE ST_DWithin(rpoint, 'POINT( 24.8 43.3648 )', 1000*300, True) AND feature_code != 'PPLX' ORDER BY distance;)
The weird thing is that nothing seems to be missing from the built query shown in the exception and if I run that query on my database it works properly. How can I make this work?
LATER EDIT:
Apparently the problem actually lies at PDO level and is caused by the fact that I am trying to add some parameters inside a quoted string:
(ST_Distance(rpoint, 'POINT( ? ? )', True)/1000)
See the 'POINT( ? ? )' parts. If I remove all the quotes from my query then it works but of course it is not a valid postgis query anymore. Anybody know how this query should be written so that PDO will accept it ?
