The spatial extensions usually require inserts in the following format: INSERT INTO `locations` (name, point) VALUES ("location name",GeomFromText(''POINT(<lng> <lat>'')); And reads as SELECT name, AsText(point) AS point FROM locations; While I understand there''s methods to issue custom finder commands, I don''t recall seeing anything about custom inserts/updates. Does anyone have any recommendations on how I might handle a situation like this? Thanks in advance. Noah
