- #開發用工具操作數據庫，誤刪除了一個表，時間大概在2012-05-18，刪除表數據後，自增字段從1開始了，判斷工具是做了truncate操作，到binlog裏面搜
- -bash-3.2$ mysqlbinlog mysql-bin.000423 -vv |grep watch_list|grep truncate
- truncate table `watch_lists`
- #找到確實存是做了truncate操作。把BINLOG導出，找到操作的準確時間點
- -bash-3.2$ mysqlbinlog mysql-bin.000423 -vv --result-file=/home/bruce/watch_list.txt
- #120518 21:11:03 server id 21528 end_log_pos 273662669 Query thread_id=56426579 exec_time=1 error_code=0
- SET TIMESTAMP=1337393463/*!*/;
- truncate table `watch_lists`

- #時間點在2012-05-18 21:11:03
- #需要找回的數據在備份時間點T1到這個時間點T2之間的數據。備份時間在2012-05-18 12:30:00
- #把這段時間的操作記錄取出
- -bash-3.2$ mysqlbinlog mysql-bin.000423 -vv --start-datetime='2012-05-18 12:30:00' --stop-datetime='2012-05-18 21:11:03' --result-file=/home/bruce/watch_list.txt
- #取出SQL語句
- -bash-3.2$ grep -i watch_lists watch_list.txt
- INSERT INTO `watch_lists` (user_id,watch_@@@@,watch_@@@@,watch_@@@@,watch_@@@@,added_@@@@) VALUES ('13946','2','569226','@@@@','1','20120518185639')
- INSERT INTO `watch_lists` (user_id,watch_@@@@,watch_@@@@,watch_@@@@,watch_@@@@,added_@@@@) VALUES ('2147','2','2841877','@@@@','1','20120518185639')
