我们通常在数据库中有n多表和字段。如何通过页面上查看到的值去知道，这个值存放在那张表和字段上。

Create PROCEDURE [dbo].[SP_FindValueInDB](    @value VARCHAR(1024))        ASBEGINSET 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 CURSORFOR    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 TABLESINTO @table, @column  WHILE @@FETCH_STATUS = 0BEGIN     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 + ''')'    print @sql   EXEC(@sql)      FETCH NEXT FROM TABLES    INTO @table, @columnEND  CLOSE TABLESDEALLOCATE TABLES  SELECT * FROM #t  DROP TABLE #t  End EXEC SP_FindValueInDB 'O6UJ9A000002'
