mysql数据库中,通过mysqldump工具仅将某个库的所有表的定义进行转储

需求描述:

　　在研究mysqldump工具的使用,想的是如何将某个库下的,或者某个表的表的定义(表结构创建语句)进行转储

操作过程:

1.通过--no-data参数,就可以将某个库的表定义进行转储

[mysql@redhat6 MysqlDb_Backup]$ mysqldump -uroot -p --no-data top_server > Db_Top_server_OnlyTableDefinitions_2018--.sql
Enter password:
[mysql@redhat6 MysqlDb_Backup]$ ls -ltr
total
-rw-rw-r--  mysql mysql     Apr  : Tables_Backup_2018--.sql
-rw-rw-r--  mysql mysql  Apr  : FullBackup_2018--.sql
-rw-rw-r--  mysql mysql     Apr  : Db_Top_server_OnlyTableDefinitions_2018--.sql

2.查看转储出来的SQL文件

--
-- Table structure for table `flow_node_info`
--

DROP TABLE IF EXISTS `flow_node_info`;
/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `flow_node_info` (
  `id` int() NOT NULL AUTO_INCREMENT,
  `flow_id` int() DEFAULT NULL,
  `node_name` varchar() DEFAULT NULL,
  `node_code` varchar() DEFAULT NULL,
  `role_id` int() DEFAULT NULL,
  `audit_user` varchar() DEFAULT NULL COMMENT '测试',
  `creat_time` datetime DEFAULT NULL,
  `update_time` datetime DEFAULT NULL,
  `node_sort` int() DEFAULT NULL,
  `dept_id` int() DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT= DEFAULT CHARSET=utf8 COMMENT='测试';
/*!40101 SET character_set_client = @saved_cs_client */;

--
-- Table structure for table `goods_alert_info`
--

DROP TABLE IF EXISTS `goods_alert_info`;
/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `goods_alert_info` (
  `id` int() NOT NULL AUTO_INCREMENT,
  `goods_type` varchar() DEFAULT NULL,
  `goods_attr` varchar() DEFAULT NULL,
  `goods_num` int() DEFAULT NULL,
  `total_time` datetime DEFAULT NULL,
  `alert_line` int() DEFAULT NULL,
  `alert_mode` char() DEFAULT NULL COMMENT '系统测试',
  `alert_object` varchar() DEFAULT NULL,
  `alert_freq` int() DEFAULT NULL,
  `alert_time` datetime DEFAULT NULL,
  `alert_type` char() DEFAULT NULL COMMENT '测试',
  `creat_time` datetime DEFAULT NULL,
  `update_time` datetime DEFAULT NULL,
  `dept_id` int() DEFAULT NULL,
  `store_id` int() DEFAULT NULL,
  `stock_id` int() DEFAULT NULL,
  `alert_up` int() DEFAULT NULL,
  `alert_down` int() DEFAULT NULL,
  `alert_status` char() DEFAULT NULL,
  `alert_set` char() DEFAULT NULL,
  `type_id` int() DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT= DEFAULT CHARSET=utf8 COMMENT='测试\r\n';
/*!40101 SET character_set_client = @saved_cs_client */;

备注:都是各个表的删除语句,创建表语句,各个表之间没有INSERT语句.

3.对某个库下的某几个表的定义进行转储

[mysql@redhat6 MysqlDb_Backup]$ mysqldump -uroot -p --no-data top_server supplier_goods_type store_goods_rela > TableDefinition_2018--.sql
Enter password:
[mysql@redhat6 MysqlDb_Backup]$ ls -ltr
total
-rw-rw-r--  mysql mysql     Apr  : Tables_Backup_2018--.sql
-rw-rw-r--  mysql mysql  Apr  : FullBackup_2018--.sql
-rw-rw-r--  mysql mysql     Apr  : Db_Top_server_OnlyTableDefinitions_2018--.sql
-rw-rw-r--  mysql mysql      Apr  : TableDefinition_2018--.sql

备注:标记为红色的部分是top_server中的表

4.查看生成的SQL转储文件

备注:发现转储出来的都是表的创建语句.
