查询字段的值属于数据库中的哪个表的哪个列

输入数据库中包含的某一个字段的值查询到它所归属的表和字段,返回两列数据,第一列是此值归属的表名;第二列是此值对应的第一列中的表的列名。sql实现如下:

USE [数据库名]
GO
/****** Object:  StoredProcedure [dbo].[SP_FindValueInDB]    Script Date: 2017/3/5 10:35:01 
--此存储过程用于查询一个值属于数据库中的那张表的哪个列,返回结果为两列,一列是表名,一列是列名
******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[SP_FindValueInDB] 
( 
    @value VARCHAR(1024) 
)         
AS 
BEGIN 

    -- 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
