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

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 + ''', '''

EXEC(@sql)
FETCH NEXT FROM TABLES

END
CLOSE TABLES
DEALLOCATE TABLES
SELECT *
FROM #t
DROP TABLE #t

例如，要查詢值'BBQ CHIC SW'，結果如下：
返回三條記錄，說明這個值存在于三個表中，分別為_dts_menudef, g_dts_menudef和g_recipe中，字段名分別為name1, name1, name。
