unionを使用して3つのクエリの数を合計しようとしています。これらのクエリには、groupby句も含まれています。以下は私が書いた私の質問です：

select 
       extract(year from start_date), 
       extract(month from start_date),
       APPLICATION_TYPE,
       sum(TOTAL) as Overall_TOTAL
from (
select 
       extract(year from A.start_date) as Start_Year, 
       extract(month from A.start_date) as Start_Month,
       A.APPLICATION_TYPE as Type,
       count(A.TRANSACTION_NUMBER) as Total
from lnr_application A
where 
      A.START_DATE >= to_date('&sdate','DD/MM/YYYY')
      and A.START_DATE <= to_date('&edate','DD/MM/YYYY')  
      and A.permission_type = 'HRW'
      and A.status_cd in ('AP')
group by extract(year from start_date), extract(month from start_date), A.APPLICATION_TYPE
union all
select 
       extract (year from A.tstamp) as Start_Year, 
       extract (month from A.tstamp) as Start_Month, 
       A.application_type as Type,
       count(A.transaction_number) as Total
from lnr_application A
where 
      A.permission_type = 'HRW'
      and A.status_cd in ('RF')
      and trunc(A.tstamp) >= to_date ('&sdate','dd/mm/yyyy')
      and trunc(A.tstamp) <= to_date ('&edate','dd/mm/yy')
group by extract (year from A.tstamp), extract (month from A.tstamp), A.application_type 
union all
select 
       extract (year from A.tstamp) as Start_Year, 
       extract (month from A.tstamp) as Start_Month, 
       A.application_type as Type, 
       count(A.transaction_number) as Total
from lnr_application A
where 
      A.permission_type = 'HRW'
      and A.status_cd in ('CL')
      and trunc(A.tstamp) >= to_date ('&sdate','dd/mm/yyyy')
      and trunc(A.tstamp) <= to_date ('&edate','dd/mm/yy')      
group by extract (year from A.tstamp), extract (month from A.tstamp), A.application_type
) tmp
group by extract(year from start_date), extract(month from start_date), APPLICATION_TYPE
order by extract(year from start_date), extract(month from start_date), APPLICATION_TYPE

クエリを実行するStart_Dateと、無効な識別子であるエラーメッセージが表示されます。合計コンポーネントを上から削除すると、つまり3つのクエリすべてを結合すると、次の結果が得られます。

2011    7   A   627 
2011    7   A   21 
2011    7   A   1 
2011    7   C   1585 
2011    7   C   1    
2011    7   I   1 
2011    7   I   154 
2011    7   I   3

以下のように、それぞれの年、月、およびアプリケーションタイプのカウントの合計を合計したいと思います。

2011    7   A   649
2011    7   C   1586 
2011    7   I   158

誰か助けてくれませんか？

ユニオンの SELECT ステートメントでは、EXTRACT ステートメントの代わりに Start_Year と Start_Month を使用する必要があります。また、Application_Type の代わりに Type を使用します。

3 つのユニオンすべてのサブクエリを 1 つのクエリに結合すると、追加のインライン ビューが不要になり、次の単純なクエリにつながります。

select extract(year from a.start_date)
     , extract(month from a.start_date)
     , a.application_type
     , sum(a.total) as overall_total
  from lnr_application a
 where a.permission_type = 'HRW'
   and a.status_cd in ('AP','RF','CL')
   and a.tstamp between to_date('&sdate','dd/mm/yyyy') and to_date('&edate','dd/mm/yyyy') + interval '1' day - interval '1' second
 group by extract(year from a.start_date)
     , extract(month from a.start_date)
     , a.application_type
 order by extract(year from a.start_date)
     , extract(month from a.start_date)
     , a.application_type

そして、2 回抽出する代わりに trunc(...,'mm') を使用して、さらに単純化します。

select extract(year from trunc(a.start_date,'mm'))
     , extract(month from trunc(a.start_date,'mm'))
     , a.application_type
     , sum(a.total) as overall_total
  from lnr_application a
 where a.permission_type = 'HRW'
   and a.status_cd in ('AP','RF','CL')
   and a.tstamp between to_date('&sdate','dd/mm/yyyy') and to_date('&sdate','dd/mm/yyyy') + interval '1' day - interval '1' second
 group by trunc(a.start_date,'mm')
     , a.application_type
 order by trunc(a.start_date,'mm')
     , a.application_type

よろしく、
ロブ。
