"Geçici kullanma; filesort sorunu kullanma" olup olmadığını düşünüyorum, ya da ben çok sütun dizini oluşturmak gerekir ama nasıl düzeltemiyorum bilmiyorum. Tavsiye lütfen.

Güncelleme 1:

Tms_door_record_raw tablosuna çoklu sütun dizini ekledikten sonra (KEY card_no_record_time( card_no, record_time)) SQL yürütmesi 11 dakikadan 3.2 saniyeye düştü

Açıklamayı sql tekrar çalıştırın. İçin birleştirme tablosu anahtarı dr, gösterdiği ekstra sütunda da (card_no) 'dan (card_no, record_time) değiştirildiUsing where; Using index

Aşağıdakiler yürütme süresine yardımcı olmalıdır:

  • ORDER BYkesinlikle gerekli değilse kaldırın
  • drtablonun birleşiminiWHERE 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')
  • GROUP BY, şimdi gerekli olmayabilir
  • dizini tms_door_record_rawikisini de içerecek şekilde genişletme card_noverecord_time

Bunu test edin ve ilerleme olup olmadığını görün. Başka adımlar gerekli olabilir, ancak umarım bu doğru yöndedir.

GROUP BY grubunu kaldırın.
(Mantıksal olarak geçerli) kopyalarınız varsa, bunları erken aşamada kaldırın.

emin, ben geçerli tablodan dizini kaldırmak kez ben sql yürütme zamanında tekrar güncelleyecek. Ancak c.card_no tarafından grup kaldıramadı, çünkü tms_door_record_rawtablo tek kart no ile birden fazla kayıt var. örneğin, kart 0001 1 gün içinde birkaç giriş / çıkış kayıtları var, bu yüzden sadece o gün kayıt varsa ihtiyaç duyduğum çoklu kayıt gösterecektir.

Teşekkür ederim. Ben katılmadan önce tms_door_record_raw üzerinde toplama denemenizi öneririz.
