Mysql разные значения для разных таблиц. Возможно ли это в 1 запросе?

/ 06 февраля 2020

MySql Версия производственного сервера: 5.7.14-google-log (Google)

Я могу проверить на Mysql версия 8

У меня есть следующие таблицы:

  • nms_alert (id, user_attended_id)
  • nms_alert_not_attend (nms_alert_id, not_attend_id)
  • nms_employee_log (начало, конец, zone_id)

1014 есть что-то вроде: 

SELECT DISTINCT 
    # COUNT(accept),<-- How to find this?
    # COUNT(reject),<-- How to find this?
    nms_employee_log.id as idLog,
    nms_employee_log.begin as employeeBegin,
    nms_employee_log.end as employeeEnd,
    nms_employee_log.zone_id
    FROM  nms_employee_log where employee_id= 11

    (GROUP BY idLog)

Где 'принято': 

SELECT DISTINCT 
            nms_alert.id as accept, 
            nms_employee_log.id as idLog,
            nms_alert.alert_begin as dataAlert,
            nms_employee_log.begin as employeeBegin,
            nms_employee_log.end as employeeEnd,
            nms_employee_log.zone_id
            FROM `nms_alert`  
            INNER JOIN nms_employee_log on ( nms_employee_log.begin <= alert_begin AND nms_employee_log.end >= alert_begin )
            WHERE nms_employee_log.employee_id= 11  AND  INSTR( nms_alert.sent_to_zones , nms_employee_log.zone_id )
            AND nms_alert.user_attended_id=3 
        ORDER BY nms_employee_log.id DESC


accept  idLog        employeeBegin      employeeEnd   zone_id

Какой будет лучший запрос или запросы для достижения этой цели?

И наилучшая производительность?

Исходя из первоначального вопроса, это должно быть выполнимо, используя CTE (если вы на MySQL 8+) или подвыбор и CASE SUM

SELECT 
     SUM(case when accept is not null then 1 else 0 end) as countAccept
    ,SUM(case when reject is not null then 1 else 0 end) as countReject
 FROM (
SELECT DISTINCT 
    nms_alert.id as accept, 
    nms_alert_not_attend.nms_alert_id as reject, 
    nms_alert.alert_begin, 
    nms_employee_log.zone_id,
    nms_employee_log.device_type,
    nms_employee_log.model,
    nms_employee_log.wifi_network
    FROM `nms_alert`  
    INNER JOIN nms_alert_not_attend on nms_alert.id = nms_alert_not_attend.nms_alert_id 
    INNER JOIN nms_employee_log on ( nms_employee_log.begin <= alert_begin AND nms_employee_log.end >= alert_begin )
    WHERE nms_alert_not_attend.not_attend_id = 3 
    AND nms_alert.user_attended_id=3 
    AND nms_employee_log.employee_id= 11
) s
...
