MySQL Spatial + Mapserver + OGR

We were able to successfully render an output image from Mapserver with data stored in MySQL Spatial using OGR. There are many methods described around the web on how to successfully accomplish there, here's what we learned:

• As of 2009/07/31, MyGIS support is deprecated and shouldn't be used.
• The method of using OGR with a .ovf file didn't work for us, we were never able to find out why.

Mapfile Syntax

Simply specifying the OGR DSN in the CONNECTION statement of your LAYER definition proved successful.

  LAYER
    NAME "##LAYERNAME##"
    STATUS OFF
    CONNECTIONTYPE OGR
    CONNECTION 'MYSQL:##DATABASE##,user=##USERNAME##,pass=##PASSWORD##,tables=##TABLE##,##TABLE##,##TABLE##'
    DATA 'SELECT geom AS the_geom FROM ##TABLE##'

    TYPE POINT
    METADATA
        "WMS_TITLE"      "title"
        "WMS_ABSTRACT"   "QRAs"
        "WMS_SRS"        "EPSG:4326 EPSG:900913"
        "WMS_EXTENT"     "-180 -90 180 90"
    END
    CLASS
      COLOR 255 0 0
      SIZE 20
    END
  END

TABLE Schema and Data

Here's the table structure that was used.

-- 
-- Table structure for table `oc_ds_data`
-- 

CREATE TABLE IF NOT EXISTS `##TABLE##` (
  `id` int(10) unsigned NOT NULL auto_increment,
  `geom` geometry NOT NULL,
  `field0` varchar(255) default NULL,
  `field1` varchar(255) default NULL,
  `field2` varchar(255) default NULL,
  `field3` varchar(255) default NULL,
  `field4` varchar(255) default NULL,
  `field5` varchar(255) default NULL,
  `field6` varchar(255) default NULL,
  `field7` varchar(255) default NULL,
  `field8` varchar(255) default NULL,
  `field9` varchar(255) default NULL,
  PRIMARY KEY  (`id`),
  KEY `oc_ds_id` (`oc_ds_id`),
  KEY `guid` (`guid`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8;

INSERT INTO `oc_ds_data` (`id`, `geom`, `field0`, `field1`, `field2`, `field3`, `field4`, `field5`, `field6`, `field7`, `field8`, `field9`) VALUES 
(1, GeomFromText('POINT(-105.08148 39.75366)'), ' One', NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL),
(2, GeomFromText('POINT(-105.07148 39.85366)'), ' Two', NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL),
(3, GeomFromText('POINT(-105.06148 39.95366)'), ' Three', NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL),
(4, GeomFromText('POINT(-105.05148 40.05366)'), ' Four', NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL),
(5, GeomFromText('POINT(-105.04148 40.15366)'), ' Five', NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL);
