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=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=9' at line 11 SQL=CREATE TABLE IF NOT EXISTS `d3vm0_usergroups` ( `id` int(10) unsigned NOT NULL AUTO_INCREMENT COMMENT 'Primary Key', `parent_id` int(10) unsigned NOT NULL DEFAULT '0' COMMENT 'Adjacency List Reference Id', `lft` int(11) NOT NULL DEFAULT '0' COMMENT 'Nested set lft.', `rgt` int(11) NOT NULL DEFAULT '0' COMMENT 'Nested set 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=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=9

Table 'testone.d3vm0_usergroups' doesn't exist SQL=INSERT INTO `d3vm0_usergroups` (`id`, `parent_id`, `lft`, `rgt`, `title`) VALUES (1, 0, 1, 18, 'Public'), (2, 1, 8, 15, 'Registered'), (3, 2, 9, 14, 'Author'), (4, 3, 10, 13, 'Editor'), (5, 4, 11, 12, 'Publisher'), (6, 1, 4, 7, 'Manager'), (7, 6, 5, 6, 'Administrator'), (8, 1, 16, 17, 'Super Users'), (9, 1, 2, 3, 'Guest')

Answer 1

Your CREATE TABLE failed , so it can not execute INSERT statement, because there is no table to INSERT.

CREATE TABLE gets an error on USING BTREE statement. i am not sure but perhaps this works. CREATE...(lft,rgt) USING BTREE (lft,rgt))... Also you can not insert into auto-increment column
