「一時的な使用; filesortの使用に関する問題」か、複数列のインデックスを作成する必要があるかどうかを考えていますが、修正方法がわかりません。お知らせ下さい。

更新1：

Tms_door_record_rawテーブルに複数列のインデックスを追加した後（KEY card_no_record_time（card_no、record_time））SQLの実行が11分から3.2秒に減少しました

Explain SQLを再度実行します。 drの結合テーブルキーは、表示されている追加の列でも（card_no）から（card_no、record_time）に変更されましたUsing where; Using index

以下は実行時間に役立ちます：

  • 厳密に必要でない場合は、_ORDER BY_を削除します
  • drテーブルの結合をWHERE EXISTS (SELECT 1 FROM tms_door_record_raw As dr WHERE c.card_no = dr.card_no AND dr.record_time BETWEEN '2016-11-01' AND '2016-11-02')に置き換えます
  • _GROUP BY_、不要になった可能性があります
  • _tms_door_record_raw_のインデックスを拡大して、_card_no_と_record_time_の両方を含める

これをテストして、進行が行われているかどうかを確認します。さらなるステップが必要かもしれませんが、うまくいけばこれは正しい方向にあります。

GROUP BYを削除します。
（論理的に有効な）重複がある場合は、初期段階でそれらを削除します。
