**解析出标准SQL**
```bash
python binlog2sql.py -h127.0.0.1 -P3306 -uadmin -p'admin' -d dbname -t table1 table2 --start-file='mysql-bin.000002'

输出：
INSERT INTO d(`did`, `updateTime`, `uid`) VALUES (18, '2016-12-07 14:01:14', 4);
INSERT INTO c(`id`, `name`) VALUES (0, 'b');
UPDATE d SET `did`=17, `updateTime`='2016-12-07 14:01:14', `uid`=4 WHERE `did`=18 AND `updateTime`='2016-12-07 14:01:14' AND `uid`=4 LIMIT 1;
DELETE FROM c WHERE `id`=0 AND `name`='b' LIMIT 1;
