mysqldump参数之-d -t -T

-d

只生成创建表结构的语句

mysqldump -uroot -p123456 -d lmis md_goods_type > goods_d.sql

cat goods_d.sql

DROP TABLE IF EXISTS `md_goods_type`;
/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `md_goods_type` (
`ID` varchar(40) NOT NULL,
`code` varchar(40) NOT NULL,
`type` varchar(60) NOT NULL,
`is3c` varchar(10) NOT NULL COMMENT '0:否/1:是',
`remark` varchar(255) DEFAULT NULL,
`status` varchar(4) NOT NULL COMMENT '1:生效/0:失效',
`create_time` datetime DEFAULT NULL,
`create_user` varchar(40) DEFAULT NULL,
`modify_time` datetime DEFAULT NULL,
`modify_user` varchar(40) DEFAULT NULL,
PRIMARY KEY (`ID`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

-t

只生成插入数据的语句

mysqldump -uroot -p123456 -t lmis md_goods_type > goods_t.sql

cat goods_t.sql

LOCK TABLES `md_goods_type` WRITE;
/*!40000 ALTER TABLE `md_goods_type` DISABLE KEYS */;
INSERT INTO `md_goods_type` VALUES ('1A9ACDFFCBBE4D0885A086D1CE46E29F','HWLX_ZJ','灶具','1','','1','2015-05-29 14:10:48','user1',NULL,NULL),('1CDB101AE32F4761B4420BE188F643B1','HWLX_DN','电脑','1','','1','2015-05-29 14:09:01','user1',NULL,NULL),('828A52D2453A4FB18B63F74C153A53CB','HWLX_YJ','烟机','1','','1','2015-05-29 14:10:40','user1',NULL,NULL),('C98D2632A80B4B00A28410D6B468F871','HWLX_KT','空调','1','','1','2015-05-29 14:09:24','user1',NULL,NULL);
/*!40000 ALTER TABLE `md_goods_type` ENABLE KEYS */;
UNLOCK TABLES;

-T

-T必须加目录，且不用重定向某个文件，自动生成两个文件：一个.sql文件，创建表结构的语句；一个.txt文件，数据文件，相当于select into outfile

mysqldump -uroot -p123456 -T /tmp lmis md_goods_type

cat md_goods_type.sql

DROP TABLE IF EXISTS `md_goods_type`;
/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `md_goods_type` (
`ID` varchar(40) NOT NULL,
`code` varchar(40) NOT NULL,
`type` varchar(60) NOT NULL,
`is3c` varchar(10) NOT NULL COMMENT '0:否/1:是',
`remark` varchar(255) DEFAULT NULL,
`status` varchar(4) NOT NULL COMMENT '1:生效/0:失效',
`create_time` datetime DEFAULT NULL,
`create_user` varchar(40) DEFAULT NULL,
`modify_time` datetime DEFAULT NULL,
`modify_user` varchar(40) DEFAULT NULL,
PRIMARY KEY (`ID`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

可以格式化数据文件，比如字段用双引号引起，字段之前使用逗号隔开

mysqldump -uroot -p123456 -T /tmp lmis md_goods_type--fields-enclosed-by=\" --fields-terminated-by=,
