MySQL에서 재귀를 이용해 더미 데이터 삽입하기)

PK를 제외한 데이터는 모두 동일하게 복사하는데, 데이터도 랜덤으로 다른 값 생성해서 넣는 것도 가능할듯

CREATE TABLE `salaries` (
  `sal_id` int NOT NULL AUTO_INCREMENT,
  `emp_no` varchar(45) DEFAULT NULL,
  `amount` varchar(45) NOT NULL,
  PRIMARY KEY (`sal_id`,`amount`)
) ENGINE=InnoDB AUTO_INCREMENT=5635994 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;


INSERT INTO salaries(emp_no, amount)
(SELECT emp_no, amount FROM salaries);
