MySQL 버전이 5.5.3 미만일 때 이러한 유형의 오류가 발생합니다. 이는 MySQL 버전 5.5.3에서 "utf8mb4"가 도입되었기 때문입니다.
먼저 현재 버전을 확인해야 합니다. 5.5.3 미만인 경우 위의 오류를 해결하려면 업그레이드해야 합니다.
현재 버전 확인 -
mysql> select version();
여기에서 우리의 MySQL 버전은 5.5.3 이상입니다 -
+-----------+ | version() | +-----------+ | 8.0.12 | +-----------+ 1 row in set (0.00 sec)
이제 오류 1115를 제공한 동일한 쿼리가 올바른 결과를 표시합니다. 지금 MySQL의 모든 문자 집합을 확인하려면 아래 쿼리를 사용하십시오.
mysql> show character set;
다음은 "utf8mb4"가 올바르게 표시되는 출력입니다.
