Question

如何在if条件之后重新启动此游标，并希望row_number在answer.want中再次从1开始，从if条件的结束点重新启动游标。

  declare @SUM DECIMAL(20,2)
  declare @EMPCODE varchar(10)
  declare @NETPAY DECIMAL(10,2)
  declare ABC scroll cursor for 
  select EMPCODE,NETPAY from TXXL where DATE='04-30-2015'
  open ABC
  declare @TEMP table(
  EMPCODE varchar(10) primary key,
  NETPAY DECIMAL(10,2),
  SUM  varchar(max)
   )

  set @SUM=0
  fetch first from ABC into @EMPCODE,@NETPAY

  while @@fetch_status=0

  begin

  fetch next from ABC into @EMPCODE,@NETPAY

  SET @SUM=@SUM+@NETPAY


  if(@SUM<=900000)



  insert into @TEMP(EMPCODE,NETPAY,SUM) values(@EMPCODE,@NETPAY,@SUM)



  end

  select ROW_NUMBER() OVER(ORDER BY EMPCODE) ROWNUMBER,EMPCODE,NETPAY,SUM from @TEMP
close ABC
deallocate ABC

这个光标给出了答案，光标在000179 EMPCODE之后停止工作，因为下一个代码的总和大于900000我想用ROWnumber 1开始下一个代码并且总和那样这个样本的总和： -

ROWNUMBER   EMPCODE NETPAY      SUM
       1    000066  29079.00    29079.00
