PK가 oracle sql에서 위반했습니다

Question

누구든지이 문제를 해결할 수 있는지 궁금합니다. SQL에서 모든 것을 실행했지만 그 오류가 발생했습니다.

Error report: SQL Error: ORA-00001: unique constraint (GAMES.ATHLETE_PK) violated 00001. 00000 - "unique constraint (%s.%s) violated" *Cause: An UPDATE or INSERT statement attempted to insert a duplicate key. For Trusted Oracle configured in DBMS MAC mode, you may see this message if a duplicate entry exists at a different level. *Action: Either remove the unique restriction or do not insert the key.

한 번에 모든 레코드를 삽입하려고합니다. 시퀀스를 사용하여 새로운 기본 키를 생성 할 수도 있습니다. 나는 하나씩 하나씩 삽입 해 보았습니다. 하지만 한번에 모두 삽입하면 오류가 발생합니다 ...

Answer 1

게시 된 코드는 INSERT ALL 구문을 사용하여 단일 명령문에 여러 행을 삽입합니다. 각 행에 고유 식별자를 생성하기 위해 시퀀스 NEXTVAL을 사용하려고 시도합니다. NEXTVAL의 기능에 documentation is quite clear

:

"Within a single SQL statement containing a reference to NEXTVAL, Oracle increments the sequence once"

그래서 NEXTVAL에 이러한 호출의 각 시퀀스에서 같은 값을 반환합니다, 그래서 문은 ORA-00001 던진다.

문제는 OP 코드가 다중 테이블 삽입 구문을 잘못 사용하고 있다는 것입니다. 하나의 원본 데이터 집합에서 여러 테이블로 행을 분산하거나 행을 조건부로 하나의 테이블로 조작하기위한 것입니다. 두 경우 모두 소스 데이터에 이미 기본 키가 있다고 가정합니다.

ID를 하드 코딩하여 여러 개의 단일 테이블 삽입 문을 사용하는 방법부터 다양한 방법으로이 문제를 해결할 수 있습니다./: - 마지막 총알 [여기] (HTTP를 참조
