Поиск строки во всех таблицах, строках и столбцах БД

Question

Я потерян в большой базе данных и не могу найти, откуда берутся данные. Мне было интересно, возможно ли в SQL Server 2005 искать строку во всех таблицах, строках и столбцах базы данных?

У кого-нибудь есть идея, возможно ли это и как?

This procedure is for finding any string or date in all tables
if search string is date, its format should be yyyy-MM-dd

Я думаю, что это может быть самый простой способ найти строку во всех строках вашей базы данных - без использования курсоров и FOR XML -.

CREATE PROCEDURE SPFindAll (@find VARCHAR(max) = '')
AS
BEGIN
    SET NOCOUNT ON;
    --
    DECLARE @query VARCHAR(max) = ''

    SELECT  @query = @query + 
            CASE 
                WHEN @query = '' THEN '' 
                ELSE ' UNION ALL '
            END +
            'SELECT ''' + s.name + ''' As schemaName, ''' + t.name + ''' As tableName, ''' + c.name + ''' As ColumnName, [' + c.name + '] COLLATE DATABASE_DEFAULT As [Data] FROM [' + s.name + '].[' + t.name + '] WHERE [' + c.name + '] Like ''%' + @find + '%'''
    FROM 
        sys.schemas s
        INNER JOIN
        sys.tables t ON s.[schema_id] = t.[schema_id]
        INNER JOIN 
        sys.columns c ON t.[object_id] = c.[object_id]
        INNER JOIN
        sys.types ty ON c.user_type_id = ty.user_type_id
    WHERE
        ty.name LIKE '%char'

    EXEC(@query)
END

Создав эту хранимую процедуру, вы можете запустить ее для любой строки, которую хотите найти, например:

EXEC SPFindAll 'Hello World'

Результат будет таким:

schemaName | tableName | columnName | Data
-----------+-----------+------------+-----------------------
schema1    | Table1    | Column1    | Hello World
schema1    | Table1    | Column1    | Hello World!
schema1    | Table2    | Column1    | I say "Hello World".
schema1    | Table2    | Column2    | Hello World

Чтобы «узнать, откуда поступают данные», вы можете запустить SQL Profiler, запустить свой отчет или приложение, и вы увидите все запросы, выполненные для вашей базы данных.

Answer 4

Этот запрос может помочь вам.

DECLARE
@search_string  VARCHAR(100),
@table_name     SYSNAME,
@table_id       INT,
@column_name    SYSNAME,
@sql_string     VARCHAR(2000)

SET @search_string = 'StringtoSearch'

DECLARE tables_cur CURSOR FOR SELECT ss.name +'.'+ so.name [name], object_id FROM sys.objects so INNER JOIN sys.schemas ss ON so.schema_id = ss.schema_id WHERE  type = 'U'

OPEN tables_cur

FETCH NEXT FROM tables_cur INTO @table_name, @table_id

WHILE (@@FETCH_STATUS = 0)
BEGIN
    DECLARE columns_cur CURSOR FOR SELECT name FROM sys.columns WHERE object_id = @table_id 
        AND system_type_id IN (167, 175, 231, 239, 99)

    OPEN columns_cur

    FETCH NEXT FROM columns_cur INTO @column_name
        WHILE (@@FETCH_STATUS = 0)
        BEGIN
            SET @sql_string = 'IF EXISTS (SELECT * FROM ' + @table_name + ' WHERE [' + @column_name + '] 
            LIKE ''%' + @search_string + '%'') PRINT ''' + @table_name + ', ' + @column_name + ''''

            EXECUTE(@sql_string)

        FETCH NEXT FROM columns_cur INTO @column_name
        END

    CLOSE columns_cur

DEALLOCATE columns_cur

FETCH NEXT FROM tables_cur INTO @table_name, @table_id
END

CLOSE tables_cur
DEALLOCATE tables_cur

Или, вы можете использовать мой запрос здесь, должно быть проще, чем создавать sProcs для каждой БД, которую вы хотите искать: Блог FullParam SQL
