MySQL语法错误: 'USING BTREE ) ENGINE=MyISAM AUTO_INCREMENT=9 DEFAULT CHARSET=utf8 AUTOINCREMENT='

Question

我收到此错误:

CREATE TABLE `pdc5l_usergroups` (
`id` int( 10 ) unsigned NOT NULL AUTO_INCREMENT COMMENT 'Clave primaria',
`parent_id` int( 10 ) unsigned NOT NULL DEFAULT '0' COMMENT 'ID Lista de referencia adyacente',
`lft` int( 11 ) NOT NULL DEFAULT '0' COMMENT 'Anidadas conjunto lft.',
`rgt` int( 11 ) NOT NULL DEFAULT '0' COMMENT 'Anidadas conjunto rgt.',
`title` varchar( 100 ) NOT NULL DEFAULT '',
PRIMARY KEY ( `id` ) ,
UNIQUE KEY `idx_usergroup_parent_title_lookup` ( `parent_id` , `title` ) ,
KEY `idx_usergroup_title_lookup` ( `title` ) ,
KEY `idx_usergroup_adjacency_lookup` ( `parent_id` ) ,
KEY `idx_usergroup_nested_set_lookup` ( `lft` , `rgt` ) USING BTREE
) ENGINE = MYISAM AUTO_INCREMENT =9 DEFAULT CHARSET = utf8AUTOINCREMENT =9;

MySQL said: Documentation
#1064 - 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
) ENGINE=MyISAM AUTO_INCREMENT=9 DEFAULT CHARSET=utf8 AUTOINCREMENT=' at line 11 

我已经尝试过这些:

) ENGINE = MYISAM AUTO_INCREMENT =9 DEFAULT CHARSET = utf8 AUTO_INCREMENT =9;
) ENGINE = MYISAM AUTOINCREMENT =9 DEFAULT CHARSET = utf8 AUTOINCREMENT =9;
) ENGINE = MYISAM AUTOINCREMENT =9 DEFAULT CHARSET = utf8 AUTO_INCREMENT =9;

但我仍然收到错误。

phpmyadmin 是这样说的:MySQL 客户端版本:4.1.22

这是mysql版本问题。您可以在该错误中看到问题:

http://bugs.mysql.com/bug.php?id=25162

Before MySQL 5.0.60, this option can be given only before the ON tbl_name clause. Use of the option in this position is deprecated as of 5.0.60 and support for it there will be removed in a future MySQL release. If an index_type option is given in both the earlier and later positions, the final option applies.

TYPE type_name is recognized as a synonym for USING type_name. However, USING is the preferred form.
