解決方法サブクエリは複数の選択で1行以上のエラーを返します

Question

4つのテーブルから合計数を選択する非常に長いMYSQLクエリがありますが、サブクエリの1つで複数の行が返され、エラーが発生します。
これは私のクエリです：このクエリで

select created, 
    (select coalesce(sum(equal_to_dollar), 0) from capitals group by created) as capital, 

    (select coalesce(sum(incoming), 0) - coalesce(sum(outgoing), 0) from transactions where currency = 'دالر') + 
    (select coalesce(sum(equal_to_dollar), 0) from transactions where incoming != 0) - 
    (select coalesce(sum(equal_to_dollar), 0) from transactions where outgoing != 0) as total_transaction, 

    (select coalesce(sum(incoming), 0) - coalesce(sum(outgoing), 0) from temporary_clients where currency = 'دالر') + 
    (select coalesce(sum(equal_to_dollar), 0) from temporary_clients where incoming != 0) - 
    (select coalesce(sum(equal_to_dollar), 0) from temporary_clients where outgoing != 0) as total_temp_client, 

    (select coalesce(sum(outgoing), 0) - coalesce(sum(incoming), 0) from money_transmission where currency = 'دالر') + 
    (select coalesce(sum(equal_to_dollar), 0) from money_transmission where outgoing != 0) - 
    (select coalesce(sum(equal_to_dollar), 0) from money_transmission where incoming != 0) as total_transmission, 

    (select coalesce(total_transaction + total_temp_client + total_transmission, 0)) as total, 

    (select capital - abs(coalesce(total_transaction + total_temp_client + total_transmission, 0))) as result 
    from capitals group by created 

つの値以上のものを返し、as capitalで終わる最初のサブクエリは、1つの値以上を返すcreated最初の選択。
このクエリは、データベース内の各日付について、他の3つのテーブルの合計を持つ資本の計算結果を返す必要があります。
同じエラーがあり、INまたはinner joinをwhere句に使用している質問が多数確認されていますが、私のケースは異なり、何をすべきかわかりません。
どうすればこの問題を解決できるかご了承ください。

は何か試してみてください。私はあなたのデータベーススキーマを知らない原因私は本当にテストすることはできません

select created,c.sum_dollars 

    (select coalesce(sum(incoming), 0) - coalesce(sum(outgoing), 0) from transactions where currency = 'دالر') + 
    (select coalesce(sum(equal_to_dollar), 0) from transactions where incoming != 0) - 
    (select coalesce(sum(equal_to_dollar), 0) from transactions where outgoing != 0) as total_transaction, 

    (select coalesce(sum(incoming), 0) - coalesce(sum(outgoing), 0) from temporary_clients where currency = 'دالر') + 
    (select coalesce(sum(equal_to_dollar), 0) from temporary_clients where incoming != 0) - 
    (select coalesce(sum(equal_to_dollar), 0) from temporary_clients where outgoing != 0) as total_temp_client, 

    (select coalesce(sum(outgoing), 0) - coalesce(sum(incoming), 0) from money_transmission where currency = 'دالر') + 
    (select coalesce(sum(equal_to_dollar), 0) from money_transmission where outgoing != 0) - 
    (select coalesce(sum(equal_to_dollar), 0) from money_transmission where incoming != 0) as total_transmission, 

    (select coalesce(total_transaction + total_temp_client + total_transmission, 0)) as total, 

    (select capital - abs(coalesce(total_transaction + total_temp_client + total_transmission, 0))) as result 
    from capitals 
JOIN (select coalesce(sum(equal_to_dollar), 0) as sum_dollars, created from capitals group by created) c ON capitals.created = c.created 
group by created 

を。とにかくそれらの結果セットに参加する必要があります。
