(2) mysqlbinlog 精确提取sql语句
命令:mysqlbinlog -d oldgirl mysql-bin.000046
mysqlbinlog --start-position=442 --stop-position=549 mysql-bin.000046
mysqlbinlog --start-datetime="2016-04-11 21:42:45" --stop-datetime="2016-04-11 21:43:22" mysql-bin.000046
1 mysqlbinlog 记录的是 所有库的log日志
如:
/*!40019 SET @@session.max_insert_delayed_threads=0*/;
/*!50003 SET @OLD_COMPLETION_TYPE=@@COMPLETION_TYPE,COMPLETION_TYPE=0*/;

举例:
mysqlbinlog -d oldgirl mysql-bin.000046 > oldgirl.sql # cat oldgirl.sql

我只想提取含有 insert into student (name) values ('andy') 这条语句的binlog
mysqlbinlog --start-position=442 --stop-position=549 mysql-bin.000046 /*!40019 SET @@session.max_insert_delayed_threads=0*/;

命令三:用时间来指定(但是时间不准确 1s钟可很多语句)
--start-datetime
--stop-datetime（语句不会包括在stop的这个时间点 是截止线）
