查询整个数据库中某个特定值所在的表和字段的方法

CREATE PROCEDURE [dbo].[SP_FindValueInDB](    @value VARCHAR(1024))        ASBEGIN    -- SET NOCOUNT ON added to prevent extra result sets from    -- interfering with SELECT statements.SET NOCOUNT ON;DECLARE @sql VARCHAR(1024) DECLARE @table VARCHAR(64) DECLARE @column VARCHAR(64)  CREATE TABLE #t (     tablename VARCHAR(64),     columnname VARCHAR(64) )  DECLARE TABLES CURSOR FOR      SELECT o.name, c.name     FROM syscolumns c     INNER JOIN sysobjects o ON c.id = o.id     WHERE o.type = U AND c.xtype IN (167, 175, 231, 239)     ORDER BY o.name, c.name  OPEN TABLES  FETCH NEXT FROM TABLES INTO @table, @column  WHILE @@FETCH_STATUS = 0 BEGIN     SET @sql = IF EXISTS(SELECT NULL FROM [ + @table + ]      SET @sql = @sql + WHERE RTRIM(LTRIM([ + @column + ])) LIKE ‘‘% + @value + %‘‘)      SET @sql = @sql + INSERT INTO #t VALUES (‘‘‘ + @table + ‘‘‘, ‘‘‘     SET @sql = @sql + @column + ‘‘‘)      EXEC(@sql)      FETCH NEXT FROM TABLES     INTO @table, @column END  CLOSE TABLES DEALLOCATE TABLES  SELECT * FROM #t  DROP TABLE #t  End
例如,要查询‘admin’,新建一个查询输入
 
EXEC SP_FindValueInDB ‘admin‘
会返回相应记录,Tablename显示被查询数据所在表,Columnname显示被查询数据所在列。
