외국인이 포함 된 lawyer_cscd이라는 추가 테이블을 하나 생성 한 변호사, 국가,시, 구 및 지구 표가 있습니다. 위에서 언급 한 테이블 이름의 주요 관계.SQL 경고 코드 : 1364, SQLState : HY000 'district_code'필드에 기본값이 없습니다.
실제로 국가시와 구는 미리 채워진 데이터가 있습니다.이 데이터를 가져 와서 변호사와 연결하면됩니다. 나는 lawyer_cscd라는 추가 테이블을 만들었습니다.이 테이블은 모든 사람과 외래 키 관계를 가질 것입니다 5 개 개의 테이블, 내가 오류 아래
Field 'district_code' doesn't have a default value
있어 변호사 테이블에 데이터를 삽입하려고

당신은 널 (null)는 'district_code'값을 삽입하려고하지만이 열이 null이 아닌 것을 선언해야 또는이 값이 null이 아니도록 요구하는 제한이 있습니다 – scaisEdge
이 줄이 있으면 @scaisEdge lawyer.setDistrict (district); 나는 변호사 pozo와 district.getLawyers()에서 지구의 가치를 정하고있다. add (변호사); 두 가지 방법으로 값을 제공했지만 clawDao.saveLayer (변호사)는 여전히 왜 오류를 던지고 있는지 확신하지 못했습니다. – henrycharles
@scaisEdge 지난 4 일 동안이 작업을 시도해 본 결과 내가 실수 한 것을 이해할 수 없게되었습니다. – henrycharles
