Joins on spatial mysql indexes

Question

I have two tables: one with points, the other with polys.

CREATE TABLE `points` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `point` point NOT NULL,
  PR         


        

Answer 1

I have used successfully similar queries, with only one difference in data model: a spatial key on the points database. In my case:

CREATE TABLE geopoints (
  pid int(11) NOT NULL AUTO_INCREMENT,
  description varchar(255) NOT NULL DEFAULT '',
  geopoint point NOT NULL,
  PRIMARY KEY (pid),
  SPATIAL KEY geopoint (geopoint) 
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

And everything went well in queries like this:

SELECT pt.pid, x(geopoint), Y(geopoint), pl.pid, AsText(geopolygon) 
  FROM geopoints pt INNER JOIN geopolygons pl ON MBRCONTAINS(geopolygon, geopoint)
 WHERE pt.pid IN (1,2,4,5) AND pl.pid BETWEEN 1 AND 5;

my two cents,
