Magento : errore importazione da db ad un'altro (USING BTREE)

Tonight I was setting up a staging environment for a client of ours so they would have the ability to “visually” interact with the recent data migration our team has performed (OSCommerce to Magento, in case anyone was wondering).

Here’s the error I was receiving:

ERROR 1064 (42000) at line 382: You have an error in your SQL syntax; 
check the manual that corresponds to your MySQL server version for
the right syntax to use near ‘USING BTREE,
KEY `FK_ATTRIBUTE_VARCHAR_ENTITY` (`entity_id`),
KEY `FK_CATALO’ at line 9

The reason behind this is that there is an inconsistency in the way the export syntax was being handled as I imported into the staging environment (which evidently has a different MySQL version running). Thus, the staging site was expecting different syntax for the following:


– Table structure for table `catalog_category_entity_varchar`

DROP TABLE IF EXISTS `catalog_category_entity_varchar`;
CREATE TABLE `catalog_category_entity_varchar` (
`value_id` int(11) NOT NULL AUTO_INCREMENT,
`entity_type_id` smallint(5) unsigned NOT NULL DEFAULT ‘0′,
`attribute_id` smallint(5) unsigned NOT NULL DEFAULT ‘0′,
`store_id` smallint(5) unsigned NOT NULL DEFAULT ‘0′,
`entity_id` int(10) unsigned NOT NULL DEFAULT ‘0′,
`value` varchar(255) NOT NULL DEFAULT ”,
PRIMARY KEY (`value_id`),
UNIQUE KEY `IDX_BASE`
(`entity_type_id`,`entity_id`,`attribute_id`,`store_id`) USING BTREE,
KEY `FK_ATTRIBUTE_VARCHAR_ENTITY` (`entity_id`),
KEY `FK_CATALOG_CATEGORY_ENTITY_VARCHAR_ATTRIBUTE` (`attribute_id`),
KEY `FK_CATALOG_CATEGORY_ENTITY_VARCHAR_STORE` (`store_id`)
) ENGINE=InnoDB AUTO_INCREMENT=697 DEFAULT CHARSET=utf8;

As a rule of thumb, one can either

  • (1) head over to the MySQL Developer Documentation for syntax reference
  • (2) or simply check out a recent Magento export from the server they are trying to import into and determine how the “USING BTREE” statement was handled. Likewise, I simply removed the following:
UNIQUE KEY `IDX_BASE` (`entity_type_id`,`entity_id`,
`attribute_id`,`store_id`) USING BTREE,

and replaced it with this:

UNIQUE KEY `IDX_BASE` USING BTREE (`entity_type_id`,`entity_id`,
`attribute_id`,`store_id`),
