SQL语句 goto

/*********************求1+2+3+4+......................+100的和*******************************/
declare @sum smallint,@i smallint
set @i=1
set @sum=0
label:
    if (@i<=100)
         begin
            set @sum=@sum+@i
            set @i=@i+1
            goto label
         end
print @sum

================================================

都说不要用goto,可我看了一些经典sql 代码,也是常用goto的呀?大家如何看待goto呢?

  大多用到出错时的跳转,可是想问问大家,如果不用goto,用什么办法实现这个功能呢?

---------------------------------------------------------------------------

goto不是功能不好，而是会使得代码混乱，可读性差。一般改用IF等判断语句

---------------------------------------------------------------------------

我还是觉得最好不用！！  
  怕用成习惯！！  
  一多起来！跳到什么地方去了都不知道！(个人意见!!)

另外一个例子：

USE [spb2.3]
GO
/****** 对象:  StoredProcedure [dbo].[spb_WidgetInstances_UserInitialize]    脚本日期: 01/18/2010 15:55:00 ******/
SET ANSI_NULLS OFF
GO
SET QUOTED_IDENTIFIER OFF
GO
CREATE procedure [dbo].[spb_WidgetInstances_UserInitialize]
(
    @OwnerID int,
    @PageCode char(4),
    @Theme nvarchar(32)
)
as
SET Transaction Isolation Level Read UNCOMMITTED
SET NOCOUNT ON

if (@OwnerID<>0)
begin
    Begin transaction
    delete from spb_LayoutPages where OwnerID=@OwnerID and PageCode=@PageCode and Theme=@Theme
    if(@@error<>0) goto Failure
    
    delete from spb_WidgetsInZones where OwnerID=@OwnerID and ZoneID in 
        (select ZoneID from spb_WidgetZones where PageCode=@PageCode and Theme=@Theme)
    if(@@error<>0) goto Failure 
    
    insert into spb_WidgetsInZones (WidgetID,OwnerID,ZoneID,WidgetXml,DisplayOrder)
      (select W.WidgetID,@OwnerID,W.ZoneID,W.WidgetXml,W.DisplayOrder from spb_WidgetsInZones W with (nolock) inner join spb_WidgetZones Z with (nolock)
          on W.ZoneID = Z.ZoneID where W.OwnerID=0 and Z.PageCode=@PageCode and Z.Theme=@Theme)
    if(@@error<>0) goto Failure
    
    commit transaction
    return
    
    Failure:
    rollback transaction
    return
end
