Question

我正在尝试获取当前财政年度和上一个财政年度的月度总金额。我不能硬编码日期。它应该基于当前日期。日期列的格式如下：13-JAN-10 和金额是整数格式。

我希望它采用以下格式：

Month       2016-17   2017-18

June         17890    50980
July         45900    14879
August
September
October
November
December
January
February
March 
April
May

我无法超越我写的当前查询

SELECT
   CASE WHEN MONTH(sysdate)>=7 THEN
          concat(YEAR(sysdate), '-',YEAR(sysdate)+1)
   ELSE concat(YEAR(sysdate)-1,'-', YEAR(sysdate)) END AS financial_year,
   SUM(AMOUNT)
FROM TABLE a
GROUP BY financial_year ;

Answer 1

我没有太认真地检查我的日期算术，但希望这个例子可以让你知道如何解决它

设置一些测试数据：

SQL> exec dbms_random.seed(0)

PL/SQL procedure successfully completed.

--
-- 1000 random dates and values
--
SQL> create table t as
  2  select date '2016-01-01' + trunc(dbms_random.value(1,800)) dte,
  3        rownum amount
  4  from dual
  5  connect by level <= 1000;

Table created.

--
-- sample data at the extrema

SQL>
SQL> select * from t
  2  order by 1
  3  fetch first 10 rows only;

DTE           AMOUNT

这是查询。 fin_start定义了鳍年的开始（因为它不是每个人的六月： - ））

SQL> with fin_start as
  2   ( select date '2017-06-01' fs from dual )
  3  select mth, last_fin_year, this_fin_year
  4  from (
  5  select
  6    to_char(dte,'Month') mth,
  7    to_char(dte,'MM') mth_seq,
  8    fin_start.fs,
  9    sum(case when dte between add_months(fin_start.fs,-112) and fin_start.fs-1 then amount end) last_fin_year,
 10    sum(case when dte between fin_start.fs and add_months(fin_start.fs,12)-1 then amount end) this_fin_year
 11  from t, fin_start
 12  group by
 13    to_char(dte,'Month'),
 14    to_char(dte,'MM'),
 15    fin_start.fs
 16  )
 17  order by
 18    case when mth_seq >= to_char(fs,'MM') then 1 else 2 end,
 19    mth_seq;

您没有提供有关“a”表格中的列的任何线索。所以，在我的回答中，我假设你有一些YOURTABLE表，你有一些交易（订单）行。在这些行中，您有YOURTABLE.YOURDATE日期作为订单日期，YOURTABLE.YOURAMOUNT作为订单金额。

您需要按月对订单总额进行分组：

group by trunc(t.YOURDATE, 'mm')

但是如果你想在这个例子中将这些组表示为2列，你应该从YOURTABLe中选择2个（过去的一年和当前年份）。然后加入他们。这是一个例子：

with curryear as
 (select to_char(trunc(t.YOURDATE, 'mm'), 'month') dmonth,
         sum(t.YOURAMOUNT) dresults
    from YOURTABLE t
   group by trunc(t.YOURDATE, 'mm')
  having trunc(t.YOURDATE, 'mm') >= '01-JUL-2017'
   order by trunc(t.YOURDATE, 'mm') asc),
pastyear as
 (select to_char(trunc(t.YOURDATE, 'mm'), 'month') dmonth,
         sum(t.YOURAMOUNT) dresults
    from YOURTABLE t
   group by trunc(t.YOURDATE, 'mm')
  having trunc(t.YOURDATE, 'mm') between '01-JUL-2016' and '01-JUN-2017'
   order by trunc(t.YOURDATE, 'mm') asc)
select curryear.dmonth   "Month",
       pastyear.dresults    "2016-17",
       curryear.dresults "2017-18"
  from curryear, pastyear
 where curryear.dmonth = pastyear.dmonth;

希望这有帮助！
