group by 句のエラー :: MS sql.here でレコードを一意にしたいのですが、2 ～ 3 個のテーブルの結合と when 句を使用しています。group by 句を使用して区別するのはより難しく、次のようなエラーが発生します。

今分かります。後にサブクエリ名を追加する必要があります2008)

これに関するいくつかの問題の詳細に入るだけです：

サブクエリの from 句を次のように変更します。

from Member m
    inner join Member_Official_Info moi
        on m.pk_member_id=moi.fk_member_id
    left outer join Event_Members em
        on m.pk_member_id=em.fk_member_id
    left outer join Dining_Members dm
        on m.pk_member_id=em.fk_member_id
    left outer join JF2_Members jm
        on m.pk_member_id=em.fk_member_id

他のみんなと同じように、これによりおそらく group by 句の必要性がなくなると思います

また、サブクエリの where 句を次のように変更します。

where m.membership_expiry_date>='1/1/2008'
    and m.membership_expiry_date<'1/1/2009'

また、paydamt とモード コードを次のように変更します。

case when coalesce(moi.credit_card_amt,0)>0 then moi.credit_card_amt
    when coalesce(moi.cheque_amt,0)>0 then moi.cheque_amt
    case when coalesce(moi.debit_card_amt,0)>0 then moi.debit_card_amt
    case when coalesce(moi.cash_amt,0)>0 then moi.cash_amt

また、列のエイリアシングに矛盾があります。特定のポイントで、Column Name= を使用するか、「列名」として、または [列名] としても使用しています。これはかなり紛らわしいので、列に別名を付ける方法を 1 つ選択し、それをそのまま使用します。

また、結合の修正が機能し、group by を実行する必要がない場合は、サブクエリからすべてを移動する必要がないため、
