엔지니어에게 전달할 수없는 이유는 무엇입니까?

Question

오케이 이것은 업데이트입니다. MySQL Workbench를 사용하고 있습니다. 내가 엔지니어를 포워드하는 동안 내가 들어오는 것입니다. 중도에서 포워드 엔지니어링 후 결과를 볼 수 있습니다.

Answer 1

스크립트에 많은 오류가 있습니다.

CONSTRAINT `Visit Number` 
    FOREIGN KEY() 
    REFERENCES `mh23202`.`Visits`() 

빈 괄호는 모든 테이블에 당신의 오류입니다 : 당신의 외래 키가있는 테이블을 작성하지만, 참조 섹션에서 다음이 생성 테이블 명세서에 싸웁 예를 지정하지 않기 때문에 대부분이다. 외래 키의 경우 테이블의 열 이름과 참조 번호 mh23202이 있어야합니다. Visits() 해당 테이블의 열 이름이 있어야합니다.

덧글에 언급 된 바와 같이, 다른 하나는 첫 번째 것과 중복 된 스크립트에 하나의 테이블 만 생성됩니다. 가장 많이 사용하는 도구가 제대로 작동하지 않아 하나의 테이블에 대한 스크립트를 만들려고했습니다. 당신이 당신의 생성 테이블에있는 편집 한 후

편집

필드 이름 사이에 공백을 명령한다. 그것은 가지고 있으면 안되며 따옴표를 붙여야합니다. 귀하의 첫 번째 작성 진술 : 환자 번호.

Answer 2

MySQL의 오류 코드 121 : 쓰기에 키를 중복 또는 FOREIGN KEY (Visit Number)와

문제를 업데이트합니다.

Answer 3

예를 들어 동일한 이름의 제약 조건을 사용할 수 없습니다.

• 테이블 mh23202.Physician에는 "방문 번호"라는 제약 조건이 있습니다.
• 표 mh23202.Patient에는 "방문 번호"라는 제약 조건이 있습니다.
• 표 mh23202.Secretary에는 "방문 번호"라는 제약 조건이 있습니다.

항상 제약 조건 이름이 다른지 확인해야합니다. 그렇지 않으면이 오류가 발생합니다. 나는 작업대에서 비슷한 문제를 겪었다. 문제를 해결 한 이름을 바꿨습니다.
