Question

This is basic domain class

Location {
  double lat;
  double lng
}

I want to convert this query to GORM form

SELECT name, lat, lng, SQRT(
    POW(69.1 * (lat -  LAT1), 2) +
    POW(69.1 * (LNG1- lng) * COS(lat / 57.3), 2)) AS distance
FROM location ORDER BY distance;

Answer 1

You can run HQL queries that select individual columns with executeQuery:

    def results= location.executeQuery('SELECT name, lat, lng, SQRT(
    POW(69.1 * (lat -  LAT1), 2) +
    POW(69.1 * (LNG1- lng) * COS(lat / 57.3), 2)) AS distance
    FROM location ORDER BY distance')

This will return a List of Object[], e.g.

for (row in results) {
   String name= row[0]
   String lat= row[1]
   ...
}
