有時候我們想通過一個值知道這個值來自數(shù)據(jù)庫的哪個表以及哪個字段，在網(wǎng)上搜了一下，找到一個比較好的方法，通過一個存儲過程實(shí)現(xiàn)的。只需要傳入一個想要查找的值，即可查詢出這個值所在的表和字段名。

前提是要將這個存儲過程放在所查詢的數(shù)據(jù)庫。

CREATE 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
