Postgres Exception ERROR: syntax error at or near ":" Position: 46 - postgresql

Question

I'm getting SQL exception while executing the below query.
#Query(value="SELECT * FROM lat_long WHERE ST_DWithin(geom :: geography,ST_SetSRID(ST_MakePoint(:lat, :lang),4326) :: geography,1000);",nativeQuery=true)
List<LatLong>find(#Param("lat")Double lat,#Param("lang")Double lang);
Hibernate:
SELECT
*
FROM
lat_long
WHERE
ST_DWithin(geom : geography,ST_SetSRID(ST_MakePoint(?, ?),4326) : geography,1000);

Answer 1

Hibernate treats the :as a parameter placeholder, messing up your cast.
The easiest way is to use a cast() operator instead:
SELECT *
FROM lat_long
WHERE ST_DWithin(cast(geom as geography), cast(ST_SetSRID(ST_MakePoint(:lat, :lang),4326) as geography),1000)
