怎么从MySQL全库备份的dump文件中恢复某张表和表结构

这篇文章主要介绍了怎么从MySQL全库备份的dump文件中恢复某张表和表结构，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。

例如全库dump文件为test.sql

从全库备份test.sql中抽取出t_user_sign表的内容:
[root@linuxidc ~]# grep 'INSERT INTO `t_user_sign`' test.sql > /tmp/t_user_sign.sql
INSERT INTO `t_user_sign` VALUES ('913400007568317795','0','661401092936','20150101000000','60.166.38.226','2016-11-24 17:24:19','
0001221E7FF447FB96111C2510F5B80F','74-27-EA-4B-F5-A1',,...............................................................................................................
.........................................................................................................


从全库备份中test.sql抽取出t_user_sign表的建表结构:
[root@linuxidc ~]# sed -e'/./{H;$!d;}' -e 'x;/CREATE TABLE `t_user_sign`/!d;q' test.sql > /tmp/create.sql
[root@linuxidc ~]# cat /tmp/create.sql
DROP TABLE IF EXISTS `t_user_sign`;
/*!40101 SET @saved_cs_client = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `t_user_sign` (
`SH` varchar(25) DEFAULT NULL COMMENT '税号',
`ZFJH` varchar(20) DEFAULT NULL COMMENT '主分机号',
`KPJH` varchar(20) DEFAULT NULL COMMENT '开票机号',
`FXSJ` varchar(26) DEFAULT NULL COMMENT '发行时间',
`IP` varchar(20) DEFAULT NULL COMMENT '客户IP地址',
`ZCSJ` datetime DEFAULT NULL COMMENT '注册时间',
`ID` varchar(32) NOT NULL COMMENT 'ID',
`MAC` varchar(32) DEFAULT NULL COMMENT 'MAC地址',
`DQMC` varchar(120) DEFAULT NULL COMMENT '地区名称',
`DQBM` varchar(6) DEFAULT NULL COMMENT '地区编码',
`OS` varchar(120) DEFAULT NULL COMMENT '操作系统',
`SBLX` varchar(120) DEFAULT NULL COMMENT '设备类型',
`WLFWS` varchar(120) DEFAULT NULL COMMENT '网络服务商',
`LATITUDE` varchar(20) DEFAULT NULL COMMENT '维度',
`LONGITUDE` varchar(20) DEFAULT NULL COMMENT '经度',
`NAME` varchar(500) DEFAULT NULL COMMENT '企业名称',
`VERSION` varchar(30) DEFAULT NULL,
PRIMARY KEY (`ID`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
/*!40101 SET character_set_client = @saved_cs_client */;

根据binlog时间点恢复:
[root@linuxidc ~]# mysqlbinlog --start-datetime="2017-1-16 19:00:00" --stop-datetime="2017-1-16 19:38:00" mysql-bin.000398 > /tmp/time.sql

[root@idb4 tmp]# more /tmp/time.sql
