WHENcaseステートメントのそれぞれを独自の列に出力することは可能ですか？私はそれを試しましたが、運がありませんでした。私が欲しいものに最も近いのは以下です。

現在、次のようなクエリがあります。

select BH.BATCH                 as batch_number, 
       BS.TBS_DESCRIPTION       as batch_description,
       BH.NUM_VOUCHERS          as "NUM_VOUCHERS(BATCH)",
       case when VS.TVS_CODE = 1 then count(*) else 0 end as in_stock,
       case when VS.TVS_CODE = 3 then count(*) else 0 end as terminate,
       case when VS.TVS_CODE = 5 then count(*) else 0 end as in_progress,
       case when VS.TVS_CODE = 6 then count(*) else 0 end as used,
       case when VS.TVS_CODE = 8 then count(*) else 0 end as deactivate
from BATCH_HIST   bh,
     BATCH_STATUS bs,
     VOUCH_HIST   vh,
     VOUCH_STATUS vs
where substr(BH.ALLOCAT_DATE, 1, 6) = 201207
and   to_char(BH.STATUS) = BS.TBS_CODE
and   BH.BATCH = VH.BATCH
and   to_char(VH.STATUS) = VS.TVS_CODE
group by BH.BATCH,
         BS.TBS_DESCRIPTION,
         BH.NUM_VOUCHERS,
         VS.TVS_CODE
order by 1,2,3;

STATUSこれにより、それぞれが異なるレコードとして、次の出力が得られます。

BATCH_NUMBER  | BATCH_DESCRIPTION  | NUM_VOUCHERS(BATCH)  | IN_STOCK  | TERMINATE  | IN_PROGRESS  | USED  | DEACTIVATE
------------------------------------------------------------------------------------------------------------------------------
4413565       |  Allocate          |  100                 |  67       |  0         |  0           |  0    |  0
4413565       |  Allocate          |  100                 |  0        |  0         |  0           |  33   |  0
4413566       |  Allocate          |  100                 |  63       |  0         |  0           |  0    |  0
4413566       |  Allocate          |  100                 |  0        |  0         |  0           |  37   |  0

これをグループ化して、次のレコードごとに1つのレコードが存在するようにしBATCH_NUMBERます。

BATCH_NUMBER  | BATCH_DESCRIPTION  | NUM_VOUCHERS(BATCH)  | IN_STOCK  | TERMINATE  | IN_PROGRESS  | USED  | DEACTIVATE
------------------------------------------------------------------------------------------------------------------------------
4413565       |  Allocate          |  100                 |  67       |  0         |  0           |  33   |  0
4413566       |  Allocate          |  100                 |  63       |  0         |  0           |  37   |  0

あなたが書いたように、式にはgroup byが必要ですが、一致を合計すると、groupbyからtvs_codeを削除できます。

select BH.BATCH                 as batch_number, 
       BS.TBS_DESCRIPTION       as batch_description,
       BH.NUM_VOUCHERS          as "NUM_VOUCHERS(BATCH)",
       sum (case when VS.TVS_CODE = 1 then 1 else 0 end) as in_stock,
       sum (case when VS.TVS_CODE = 3 then 1 else 0 end) as terminate,
       sum (case when VS.TVS_CODE = 5 then 1 else 0 end) as in_progress,
       sum (case when VS.TVS_CODE = 6 then 1 else 0 end) as used,
       sum (case when VS.TVS_CODE = 8 then 1 else 0 end) as deactivate
from BATCH_HIST   bh,
     BATCH_STATUS bs,
     VOUCH_HIST   vh,
     VOUCH_STATUS vs
where substr(BH.ALLOCAT_DATE, 1, 6) = 201207
and   to_char(BH.STATUS) = BS.TBS_CODE
and   BH.BATCH = VH.BATCH
and   to_char(VH.STATUS) = VS.TVS_CODE
group by BH.BATCH,
         BS.TBS_DESCRIPTION,
         BH.NUM_VOUCHERS
order by 1,2,3;

これにより、現在のクエリがラップされます。多分これはあなたを助けることができます。

        subQuery.BATCH_DESCRIPTION,

        MAX(subquery.in_progress) AS in_progress,
        MAX(subquery.used) AS used,
        MAX(subquery.deactivate) AS deactivate
