查找sqlserver數據庫中某一字段在 哪

   有時候我們想通過一個值知道這個值來自數據庫的哪個表以及哪個字段,在網上搜了一下,找到一個比較好的方法,通過一個存儲過程實現的。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據庫。

  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
