mariadb에서 "Subsystem"테이블을 만들 때 오류가 계속 발생합니다. 나는 mysql을 성공적으로 실행할 수 있었지만 mariadb로 시도 할 때 나는 외래 키와 관련하여 문법과 관련이 있거나없는 것으로 추측된다. - SHOW 엔진 INNODB 상태와를 얻을 수ERROR 1005 (HY000) : 'CBDB.Subsystem'테이블을 만들 수 없습니다. (errno : 150)
ERROR 1005 (HY000): Can't create table 'CBDB.Subsystem' (errno: 150)
내가 도망 : 여기 내가 먼저 부모 테이블을 만들려고 먼저 만드는거야 테이블 ...
