[Mysql] 一些记录

1> 修改表的字段

alter table trade_market change reqype reqtype int(10) unsigned not null;
alter table trade_market drop column reqtype;
alter table trade_market add column `resnum`  int(10) unsigned not null after `reqtype`;

2> 设置密码

update mysql.user set password=PASSWORD（'新密码'） where User='root'；
flush privileges；

3> binlog 查看 参考http://dev.mysql.com/doc/refman/5.1/en/mysqlbinlog-row-events.html
