I have recently upgraded to MySQL 5.7 and was trying to run a replication from 5.6 master. However the replication fails with the following error:
Error 'Cannot get geometry object from data you send to the GEOMETRY field' on query.
Turns out it also happens when I try to import data from the mysqldump. Table structure is as follows:
CREATE TABLE `locations` (
`location_id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`country_id` int(10) unsigned NOT NULL,
`name` varchar(100) CHARACTER SET utf8 NOT NULL,
`locations_type_id` int(11) unsigned NOT NULL,
`parent_id` int(11) unsigned DEFAULT NULL,
`importance` decimal(3,2) NOT NULL DEFAULT '1.00',
`lat` decimal(10,7) DEFAULT NULL,
`lng` decimal(10,7) DEFAULT NULL,
`radius` decimal(6,3) DEFAULT NULL,
`polygon` polygon DEFAULT NULL,
PRIMARY KEY (`location_id`),
KEY `name` (`name`,`locations_type_id`,`parent_id`,`lat`,`lng`),
KEY `locations_type_id` (`locations_type_id`),
KEY `name_2` (`name`(8)),
KEY `country_id` (`country_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
It appears to me that the import is trying to insert some binary data into the polygon field but in fairness I have no idea how to make it work.
Any ideas?
