Mysqladmin은 테이블 생성 스크립트를 저장하는 작업을 수행 할 수 있습니다.

1 단계, 테이블을 만들고 행을 삽입하십시오.

create table penguins (id int primary key, myval varchar(50))
insert into penguins values(2, 'werrhhrrhrh')
insert into penguins values(25, 'weeehehehehe')
select * from penguins

2 단계 : mysql dump 명령을 사용하십시오.

mysqldump --no-data --skip-comments --host=your_database_hostname_or_ip.com -u your_username --password=your_password your_database_name penguins > penguins.sql

3 단계 : penguins.sql의 출력을 관찰하십시오.

/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;
/*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;
/*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */;
/*!40101 SET NAMES utf8 */;

DROP TABLE IF EXISTS `penguins`;
/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `penguins` (
  `id` int(11) NOT NULL,
  `myval` varchar(50) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
/*!40101 SET character_set_client = @saved_cs_client */;
/*!40103 SET TIME_ZONE=@OLD_TIME_ZONE */;

/*!40101 SET SQL_MODE=@OLD_SQL_MODE */;
/*!40014 SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS */;
/*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS */;

/*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION */;
/*!40111 SET SQL_NOTES=@OLD_SQL_NOTES */;

출력은 위와 아래의 여러 실행 조건 토큰에 의해 복잡해집니다. 다음 단계에서 원하지 않으면 필터링 할 수 있습니다.

4 단계 (선택 사항)에서 이러한 추가 실행 조건 토큰을 다음과 같이 필터링하십시오.

mysqldump --no-data --skip-comments --compact --host=your_database_hostname_or_ip.com -u your_username --password=your_password your_database_name penguins > penguins.sql

최종 출력을 생성합니다.

eric@dev /home/el $ cat penguins.sql

DROP TABLE IF EXISTS `penguins`;
CREATE TABLE `penguins` (
  `id` int(11) NOT NULL,
  `myval` varchar(50) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
