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 'DEFAUL 'C', `ex_id_calendars` int(11) DEFAULT NULL, `ex_version` varchar(' at line 8 SQL=CREATE TABLE IF NOT EXISTS `ltclg_tracktime_extensions` ( `id_extensions` int(11) NOT NULL AUTO_INCREMENT, `ex_title` varchar(50) NOT NULL, `ex_key` VARCHAR( 255 ) NULL DEFAULT NULL, `ex_commercial` tinyint(4) DEFAULT '0', `ex_valid_until` date DEFAULT NULL, `ex_id_ex_categories` int(11) DEFAULT NULL, `ex_type` ENUM( 'C', 'M', 'P', 'O' ) NOT NULL DEFAUL 'C', `ex_id_calendars` int(11) DEFAULT NULL, `ex_version` varchar(10) DEFAULT NULL, `ex_check` tinyint(4) DEFAULT NULL, `ex_update_url` varchar(255) DEFAULT NULL, `ex_enabled` tinyint(4) DEFAULT '0', `ex_j15` tinyint(4) DEFAULT NULL, `ex_j25` tinyint(4) DEFAULT NULL, `ex_j30` tinyint(4) DEFAULT NULL, `ex_note` text, PRIMARY KEY (`id_extensions`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 ;
SQL =
