SQL Query Examples

Basic query:

SELECT lat, lng, name, id, info FROM mydata;

Show each point with a selected icon:

SELECT lat, lng, name, id, info, icon FROM mydata;

Get only the data within a certain distance from a chosen point:

SELECT t.lat AS lat
      ,t.lng AS lng
      ,t.name
      ,t.id AS id
      ,t.info
      ,'' AS icon
FROM   mytable t
WHERE  t.lat IS NOT NULL
AND    t.lng IS NOT NULL
AND    (:P1_LATLNG IS NULL
     OR :P1_RADIUS IS NULL
     OR SDO_GEOM.sdo_distance
          (geom1 => SDO_GEOMETRY

            ,sdo_point     => SDO_POINT_TYPE(t.lng, t.lat, NULL)
