第一步创建以下两个日志表

  CREATE TABLE `slow_log` (   `start_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP                           ON UPDATE CURRENT_TIMESTAMP,   `user_host` mediumtext NOT NULL,   `query_time` time NOT NULL,   `lock_time` time NOT NULL,   `rows_sent` int(11) NOT NULL,   `rows_examined` int(11) NOT NULL,   `db` varchar(512) NOT NULL,   `last_insert_id` int(11) NOT NULL,   `insert_id` int(11) NOT NULL,   `server_id` int(10) unsigned NOT NULL,   `sql_text` mediumtext NOT NULL,   `thread_id` bigint(21) unsigned NOT NULL  ) ENGINE=CSV DEFAULT CHARSET=utf8 COMMENT='Slow log'

  CREATE TABLE `general_log` (   `event_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP                          ON UPDATE CURRENT_TIMESTAMP,   `user_host` mediumtext NOT NULL,   `thread_id` bigint(21) unsigned NOT NULL,   `server_id` int(10) unsigned NOT NULL,   `command_type` varchar(64) NOT NULL,   `argument` mediumtext NOT NULL  ) ENGINE=CSV DEFAULT CHARSET=utf8 COMMENT='General log'

第二步在数据库上开启查询日志

SET global general_log = 1;SET global log_output = 'table';

第三步查询日志

select * from mysql.general_log

第四步在数据库上关闭查询日志

SET global general_log = 0;

第五步清除数据库日志

truncate table mysql.general_log;
