即然经典，那就多加分啦，只要输出表名：
===============================
ALTER proc Full_Search(@string varchar(50)) 
as 
begin 

declare @tbname varchar(50) 
declare tbroy cursor for select name from sysobjects 
where xtype= 'u ' --第一个游标遍历所有的表 

open tbroy 
fetch next from tbroy into @tbname 
while @@fetch_status=0 
begin 

declare @colname varchar(50) 
declare colroy cursor for select name from syscolumns 
where id=object_id(@tbname) and xtype in ( 
select xtype from systypes 
where name in ( 'varchar ', 'nvarchar ', 'char ', 'nchar ') --数据类型为字符型的字段 
) --第二个游标是第一个游标的嵌套游标，遍历某个表的所有字段 

open colroy 
fetch next from colroy into @colname 
while @@fetch_status=0 
begin 

declare @sql nvarchar(1000),@j int 
select @sql= 'select @i=count(1) from ' +@tbname + ' where '+ @colname+ ' like '+ '''%'+@string+ '%''' 
exec sp_executesql @sql,N'@i int output',@i=@j output --输出满足条件表的记录数 
if @j> 0 
BEGIN
select 包含字串的表名=@tbname
--exec( 'select distinct '+@colname+' from ' +@tbname + ' where '+ @colname+ ' like '+ '''%'+@string+ '%''') 
END
fetch next from colroy into @colname 
end 

close colroy 
deallocate colroy 

fetch next from tbroy into @tbname 
end 
close tbroy 
deallocate tbroy 
end 
go 

exec Full_Search '123'
