SQL Server의 모든 테이블을 검색하여 문자열 찾기
SQL Server에서 데이터베이스의 모든 테이블에서 문자열을 검색할 수 있는 방법이 있습니까?
문자열 say를 검색하려고 합니다.john결과에는 다음 항목을 포함하는 테이블과 각 행이 표시됩니다.john.
저와 마찬가지로 실제 환경에서 특정 제한이 있는 경우 임시 테이블 대신 테이블 변수를 사용하고 생성 절차 대신 애드혹 쿼리를 사용할 수 있습니다.
물론 SQL 서버 인스턴스에 따라 테이블 변수를 지원해야 합니다.
검색 범위를 좁히기 위해 USE 스테이트먼트도 추가했습니다.

조금 늦었지만 유용하게 쓰였으면 좋겠다.
SSMS에 통합할 수 있는 서드파티 툴을 사용해 보는 것은 어떨까요?
저는 ApexSQL Search(100% 무료)를 사용하여 스키마와 데이터 검색 모두에서 성공을 거뒀으며, 이 기능을 갖춘 SSMS 도구 팩도 있습니다(SQL 2012에는 무료가 아니지만 상당히 저렴합니다).
위의 스토어드 프로시저는 매우 훌륭합니다.그냥 이게 훨씬 편리하다고 생각합니다.또한 datetime 열이나 GUID 열 등을 검색하려면 약간의 수정이 필요합니다.
SQL Server 2012에 대한 TechDo의 답변을 업데이트합니다.변경해야 합니다.'FROM ' + @TableName + ' (NOLOCK) ' 로. FROM ' + @TableName + 'WITH (NOLOCK) ' +
그렇지 않으면 다음 오류가 발생합니다.Deprecated feature 'Table hint without WITH' is not supported in this version of SQL Server.
다음은 업데이트된 전체 저장 프로시저입니다.

@Brandon의 훌륭한 답변을 빼앗지 않기 위해 OP는 "결과에 표와 각 행이 표시되어야 한다"고 요청했습니다.@Brandon의 답변에 따라 적절한 열을 모두 하나의 문자열로 연결하는 것만으로 다른 사용자가 사용하는 커서 사용을 피할 수 있는 레코드 수준의 솔루션을 만들었습니다.(이것이 더 잘 될 것 같은 느낌은 들지만 솔직히 결과를 비교한 적은 없습니다.여기서 자유롭게 피드백을 주세요.)
NB STRING_AGG 함수를 사용하여 열을 연결합니다.이전 버전의 SQL 서버를 사용하는 경우 온라인에서 찾을 수 있는 대체 방법 중 하나를 사용해야 할 수 있습니다.

이 스크립트를 사용하면 데이터 유형에 관계없이 데이터베이스 내의 모든 테이블에 있는 모든 필드의 모든 항목을 검색할 수 있습니다.
, 이 필드는TRY_CAST함수는 식을 올바른 데이터 유형으로 변환하려고 합니다.변환이 성공하면 변환된 값이 반환됩니다.됩니다.NULL예외를 두는 대신 말이죠.
이 방법은 데이터 유형을 잘 모르거나 검색에 동일한 스크립트를 사용하려는 경우에 매우 편리합니다.
