모든 테이블, 모든 열에서 특정 값 SQL Server 검색

구체적인 값이 있습니다. 예를 들어 문자열 'comments'라고 합시다.포맷을 업데이트하여 (*) Comments로 변경해야 하므로 데이터베이스에서 이 모든 인스턴스를 찾아야 합니다.

이거 어떻게 해?데이터베이스는 SQL Server 2000 형식입니다.

Jeff가 작성한 스크립트의 오류를 수정하기 위해 블로그 투고를 업데이트했습니다.업데이트된 스크립트는 이쪽에서 확인할 수 있습니다.SQL Server 데이터베이스의 모든 필드를 검색합니다.

요청하신 대로 스크립트를 보내드립니다만, 수시로 갱신하고 있기 때문에 블로그 투고를 검토하는 것이 좋습니다.

sys.tables 데이터베이스 뷰를 쿼리하여 테이블 이름을 꺼낸 후 이 쿼리를 사용하여 다른 쿼리를 작성하여 그 뒷면에 있는 업데이트를 수행할 수 있습니다.예:

select 'select * from '+name from sys.tables

는 시스템 카탈로그 내의 모든 테이블에 대해 선택*을 실행하는 스크립트를 제공합니다.업데이트하는 모든 테이블에서 컬럼명이 같은 것을 알고 있는 한 select 구내의 문자열을 변경하여 업데이트를 실행할 수 있습니다.그러면 스크립트는 다음과 같이 됩니다.

select 'update '+name+' set comments = ''(*)''+comments where comments like ''%comment to be updated%'' ' from sys.tables

그런 다음 테이블 쿼리에서 특정 형식의 이름을 가진 테이블만 포함하거나 업데이트 스크립트를 작성할 서브셋에 포함하도록 정의할 수도 있습니다.
