在用Navicat 导出mysql数据库的时候出现 “Cannot proceed because system tables used by Event Scheduler were found damaged at server start” . 怎么办呢?

按下面的操作吧:

查询内容:

DROP TABLE IF EXISTS event; CREATE TABLE event ( db char(64) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL DEFAULT '', name char(64) NOT NULL DEFAULT '', body longblob NOT NULL, definer char(77) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL DEFAULT '', execute_at datetime DEFAULT NULL, interval_value int(11) DEFAULT NULL, interval_field enum('YEAR','QUARTER','MONTH','DAY','HOUR','MINUTE','WEEK','SECOND','MICROSECOND','YEAR_MONTH','DAY_HOUR','DAY_MINUTE','DAY_SECOND','HOUR_MINUTE','HOUR_SECOND','MINUTE_SECOND','DAY_MICROSECOND','HOUR_MICROSECOND','MINUTE_MICROSECOND','SECOND_MICROSECOND') DEFAULT NULL, created timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, modified timestamp NOT NULL DEFAULT '0000-00-00 00:00:00', last_executed datetime DEFAULT NULL, starts datetime DEFAULT NULL, ends datetime DEFAULT NULL, status enum('ENABLED','DISABLED','SLAVESIDE_DISABLED') NOT NULL DEFAULT 'ENABLED', on_completion enum('DROP','PRESERVE') NOT NULL DEFAULT 'DROP', sql_mode set('REAL_AS_FLOAT','PIPES_AS_CONCAT','ANSI_QUOTES','IGNORE_SPACE','NOT_USED','ONLY_FULL_GROUP_BY','NO_UNSIGNED_SUBTRACTION','NO_DIR_IN_CREATE','POSTGRESQL','ORACLE','MSSQL','DB2','MAXDB','NO_KEY_OPTIONS','NO_TABLE_OPTIONS','NO_FIELD_OPTIONS','MYSQL323','MYSQL40','ANSI','NO_AUTO_VALUE_ON_ZERO','NO_BACKSLASH_ESCAPES','STRICT_TRANS_TABLES','STRICT_ALL_TABLES','NO_ZERO_IN_DATE','NO_ZERO_DATE','INVALID_DATES','ERROR_FOR_DIVISION_BY_ZERO','TRADITIONAL','NO_AUTO_CREATE_USER','HIGH_NOT_PRECEDENCE','NO_ENGINE_SUBSTITUTION','PAD_CHAR_TO_FULL_LENGTH') NOT NULL DEFAULT '', comment char(64) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL DEFAULT '', originator int(10) unsigned NOT NULL, time_zone char(64) CHARACTER SET latin1 NOT NULL DEFAULT 'SYSTEM', character_set_client char(32) CHARACTER SET utf8 COLLATE utf8_bin DEFAULT NULL, collation_connection char(32) CHARACTER SET utf8 COLLATE utf8_bin DEFAULT NULL, db_collation char(32) CHARACTER SET utf8 COLLATE utf8_bin DEFAULT NULL, body_utf8 longblob, PRIMARY KEY (db,name) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COMMENT='Events';
