Estoy pensando si es el problema "Usar temporalmente; Usar problema de clasificación de archivos", o si debería crear un índice de varias columnas, pero no sé cómo solucionarlo. Por favor avise.

Actualización 1:

Después de agregar un índice de varias columnas en la tabla tms_door_record_raw (KEY card_no_record_time( card_no, record_time)) La ejecución de SQL se redujo de 11 minutos a 3.2 segundos

Ejecute el SQL de explicación nuevamente. La clave de la tabla de unión para drha cambiado de (card_no) a (card_no, record_time) también en la columna adicional que muestraUsing where; Using index

Son todos LEFT JOIN:s necesarios o pueden reemplazarse algunos de ellosINNER JOIN:s

Lo siguiente debería ayudar con el tiempo de ejecución:

  • eliminar el ORDER BYsi no es estrictamente necesario
  • reemplazar la unión de la drmesa conWHERE 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, puede que ahora no sea necesario
  • ampliar el índice tms_door_record_rawpara incluir ambos card_noyrecord_time

Pruebe esto y vea si se está progresando. Es posible que se necesiten más pasos, pero con suerte esto va en la dirección correcta.

Retire el GRUPO POR.
Si tiene duplicados (lógicamente válidos) elimínelos en una etapa temprana.

claro, lo actualizaré nuevamente en el tiempo de ejecución de SQL una vez que elimine el índice de la tabla actual. Sin embargo, no pude eliminar el grupo por c.card_no, debido a que la tms_door_record_rawtabla tiene múltiples registros con una sola tarjeta no. Por ejemplo, la tarjeta 0001 tiene pocos registros de entrada / salida en 1 día, por lo que mostrará registros múltiples donde solo necesito si la tarjeta tiene registros ese día.

Gracias. Sugiero intentar la agregación en tms_door_record_raw antes de las uniones.
