mysql数据库误操作 binlog方式恢复数据
1、修改mysql配置文件mysql.ini，在[mysqld]节点下添加
log-bin=mysql-bin
2、重启mysql 服务器
3、查看二进制日志是否已经启动
show variables like 'log_%';
如启动会在data目录下创建logbin.index和logbin.000001两个文件，
logbin.000001 为数据备份文件
4、导出logbin.000001文件
mysqlbinlog e:/log/logbin.000001 > e:/log/log.sql
">": 导入到文件中; ">>": 追加到文件中
4.1 按指定位置导出：
c:\mysql\bin\>mysqlbinlog --start-position=185 --stop-position=338 e:/log/logbin.000001 > e:/log/log3.sql
4.2 按指定时间导出：
c:\mysql\bin\>mysqlbinlog --start-datetime="2010-01-07 11:25:56" --stop-datetime="2010-01-07 13:23:50" e:/log/logbin.000001 > e:/log/log_by_date22.sql
5、查看 log.sql 文件
