MySQL INSERT/UPDATE on POINT column

Question

I'm trying to populate my DB with geographical places of my country. One of my tables have 4 fields: ID[PK], latitude. longitude ande geoPoint

EDIT `SCDBs`.`Punto_Geografico`;

SET @lat = 18.469692;

SET @lon = -63.93212;

SET @g = 'POINT(@lat @lon)';

UPDATE Punto_Geografico SET latitude = @lat, longitude =@lon, geoPoint =@g WHERE idpunto_geografico = 0;

im getting the following error: Error Code: 1416 Cannot get geometry object from data you send to the GEOMETRY field

I'm pretty sure that 'geoPoint' field is a POINT field with a spatial index. Am i missing anything.14
