[sql] DB의 모든 테이블, 행 및 열에서 문자열 검색

ApexSQL Search 와 같은 타사 도구를 사용하는 것이 좋습니다 (아마도 다른 도구 도있을 수 있지만 무료이기 때문에이 도구를 사용합니다).

정말로 SQL 방식으로 가고 싶다면 Sorna Kumar Muthuraj가 만든 저장 프로 시저를 사용해 볼 수
있습니다. 복사 된 코드는 다음과 같습니다. 스키마의 모든 테이블에 대해이 저장 프로 시저를 실행하기 만하면됩니다 (동적 SQL 사용이 쉬움).

CREATE PROCEDURE SearchTables
 @Tablenames VARCHAR(500)
,@SearchStr NVARCHAR(60)
,@GenerateSQLOnly Bit = 0
AS

/*
    Parameters and usage

    @Tablenames        -- Provide a single table name or multiple table name with comma seperated.
                        If left blank , it will check for all the tables in the database
    @SearchStr        -- Provide the search string. Use the '%' to coin the search.
                        EX : X%--- will give data staring with X
                             %X--- will give data ending with X
                             %X%--- will give data containig  X
    @GenerateSQLOnly -- Provide 1 if you only want to generate the SQL statements without seraching the database.
                        By default it is 0 and it will search.

    Samples :

    1. To search data in a table

        EXEC SearchTables @Tablenames = 'T1'
                         ,@SearchStr  = '%TEST%'

        The above sample searches in table T1 with string containing TEST.

    2. To search in a multiple table

        EXEC SearchTables @Tablenames = 'T2'
                         ,@SearchStr  = '%TEST%'

        The above sample searches in tables T1 & T2 with string containing TEST.

    3. To search in a all table

        EXEC SearchTables @Tablenames = '%'
                         ,@SearchStr  = '%TEST%'

        The above sample searches in all table with string containing TEST.

    4. Generate the SQL for the Select statements

        EXEC SearchTables @Tablenames        = 'T1'
                         ,@SearchStr        = '%TEST%'
                         ,@GenerateSQLOnly    = 1
