对于月费报告目的,需要显示如下所述的输出.只有当月支付费用时才会在表格中输入数据,否则表格中不会显示该月份.

执行查询

select reg_id, dop,to_char(dop, 'FMMonth,YYYY') Month, status 
  from fees_status
 where dop between ('1-Jul-2012') and ('1-Dec-2012')

输出是

REG_ID  DOP         MONTH           STATUS

AE-8    7/1/2012    July,2012       PAID
AE-8    9/1/2012    September,2012  PAID
AE-8    11/1/2012   November,2012   PAID
AE-8    12/1/2012   December,2012   PAID

对于报告目的,需要输出为

REG_ID  DOP         MONTH           STATUS

AE-8    7/1/2012    July,2012       PAID
AE-8    8/1/2012    August,2012     NOTPAID
AE-8    9/1/2012    September,2012  PAID
AE-8    10/1/2012   October,2012    NOTPAID
AE-8    11/1/2012   November,2012   PAID
AE-8    12/1/2012   December,2012   PAID

有人可以帮助显示上面提到的输出吗？
