1、使用遊標

declare @sql varchar(200), @name varchar(40)declare my_cursor scroll cursor for    select name from sysobjects where type = ‘u‘ and name like ‘jobs_%‘open my_cursorfetch next from my_cursor into @namewhile(@@fetch_status=0)begin    print ‘processing ‘ + @name    set @sql = N‘alter table testbfcmisuser.‘ + @name + N‘ add note varchar(200)‘    exec(@sql)    print ‘finished‘    fetch next from my_cursor into @nameendclose my_cursordeallocate my_cursor

2、使用暫存資料表

declare @sql varchar(200), @name varchar(100), @count intselect identity(int, 1, 1) as ID, name    into #JobTable    from sysobjects    where type = ‘u‘ and name like   ‘Jobs_%‘set   @count=@@rowcountwhile   @count>0begin    select top 1 @name = name         from #JobTable        where id = @count    print    ‘processing ‘ + @name    set @sql = N‘alter table testbfcmisuser.‘ + @name + N‘ add note varchar(200)‘    exec(@sql)    print ‘finished‘        set @count = @count - 1enddrop   table   #JobTable
