クエリを少しフォーマットしました。ただし、構文が正しいかどうかはわかりません。はorder by少し寂しく見え (一致する選択項目がありません)、withが何をすべきかわかりません。

((SELECT ORGANIZATION.ORGNAME AS ORGNAME, 
    SUBSCRIPTION.ID AS SUBSCRIPTIONID,
    SUBSCRIPTION.NUMBEROFAVAILABLESEATS AS AVAILABLESEATS

元の問題は括弧の配置が原因だった可能性がありますが、何が起こっているのかの長さと複雑さのために解明するのが難しくなりました.

いくつかの提案をまとめて、はるかに短いクエリを提供します。これにより、大幅に高速になり、次の人が理解しやすくなります。

何が起こっているのか見てみましょう。2 つのほぼ同一の SELECT が接着されています。それらをメッシュ化して単一の SELECT に戻すとします。

CASE 式の形のちょっとしたロジックは、2 つの SELECT をマージして並べ替えるよりも、全体的に作業が大幅に少なくなります。

省略形を作成しない限り、すべてのテーブル名を繰り返す意味はありません:

  FROM SUBSCRIPTION SUBSCRIPTION,

WHERE句よりもFROM句で結合条件を指定した方が、次の人にわかりやすいと思われることが多いです。

SELECT ORGANIZATION.ORGNAME,
       SUBSCRIPTION.ID         AS SUBSCRIPTIONID,
       CASE WHEN SUBSCRIPTION.ISLIMITEDSEAT = 1
            THEN SUBSCRIPTION.NUMBEROFAVAILABLESEATS
            ELSE -1 
        END                    AS AVAILABLESEATS
  FROM ORGANIZATION
  JOIN CUSTOMER
    ON  CUSTOMER.PARTYID = ORGANIZATION.ID
  JOIN CUSTOMERACCOUNT
    ON  CUSTOMERACCOUNT.CUSTOMERID = CUSTOMER.ID
  JOIN SUBSCRIPTION
    AND SUBSCRIPTION.CUSTOMERACCOUNTID = CUSTOMERACCOUNT.ID
  WHERE ORGANIZATION.ISDELETED=0
    AND SUBSCRIPTION.DELETED=0
    AND CUSTOMER.ISDELETED=0
    AND SUBSCRIPTION.ISLIMITEDSEAT IN (0,1)

SUBSCRIPTION.ISLIMITEDSEAT が 0 または 1 のみのフラグである場合は、最後の行を削除します。
