复制如下代码到查询分析器运行即可

Create PROCEDURE [dbo].[SP_LookFor]
(
    @value VARCHAR(1024)
)       
AS
BEGIN

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
    INTO @table, @column
END

CLOSE TABLES
DEALLOCATE TABLES

Select *
FROM #t

Drop TABLE #t

End

执行上面的代码，再执行下面的要查找的代码
