Вопрос:

Я получаю сообщение об ошибке при использовании этого запроса в MySQL.

Логика запроса верна, и я пробовал ее в Oracle, и она работает нормально, но я получаю сообщение об ошибке при работе в MySQL.

Я просмотрел предыдущие вопросы о StackOverflow, но не нашел что-то, чтобы помочь мне.

Вот запрос:

select * from
(select PM.ID, PM.Name, PM.TIMEOUT, PMS.PROCESS_MONITOR_ID, PMS.PROCESS_START_DATE
from RATOR_IMP.PROCESS_MONITOR as PM
JOIN RATOR_IMP.PROCESS_MONITOR_STATISTIC as PMS
ON PM.ID = PMS.PROCESS_MONITOR_ID
WHERE PM.ENABLED=1 and (PM.NAME='SDRRATINGENGINE11' or PM.NAME='WORKFLOWENGINE1')
order by PMS.PROCESS_START_DATE desc)
limit 10000;

И вот ошибка:

Error Code: 1248. Every derived table must have its own alias
No soultion found for query

Лучший ответ:

Вам нужно предоставить псевдоним для подзапроса, например:

select * from
(select PM.ID, PM.Name, PM.TIMEOUT, PMS.PROCESS_MONITOR_ID, PMS.PROCESS_START_DATE
 from RATOR_IMP.PROCESS_MONITOR as PM
 JOIN RATOR_IMP.PROCESS_MONITOR_STATISTIC as PMS
 ON PM.ID = PMS.PROCESS_MONITOR_ID
 WHERE PM.ENABLED=1 and (PM.NAME='SDRRATINGENGINE11' or PM.NAME='WORKFLOWENGINE1')
 order by PMS.PROCESS_START_DATE desc) as s
limit 10000;

В документации,

Подзапросы являются законными в предложении FROM SELECT. Фактический синтаксис:

SELECT… FROM (подзапрос) [AS] name…

Предложение имени [AS] является обязательным, поскольку каждая таблица в предложении FROM должна иметь имя. Любые столбцы в списке выбора подзапроса должны иметь уникальные имена.

Ответ №1

Да вам нужно указать псевдоним для полученных данных

select x.* from
(select PM.ID, PM.Name, PM.TIMEOUT, PMS.PROCESS_MONITOR_ID, PMS.PROCESS_START_DATE
from RATOR_IMP.PROCESS_MONITOR as PM
JOIN RATOR_IMP.PROCESS_MONITOR_STATISTIC as PMS
ON PM.ID = PMS.PROCESS_MONITOR_ID
WHERE PM.ENABLED=1 and (PM.NAME='SDRRATINGENGINE11' or PM.NAME='WORKFLOWENGINE1')
order by PMS.PROCESS_START_DATE desc)x <-- here
limit 10000;

can somebody help me to find my problem here,
i think i’ve given all tables with his own «name» like TB for CB_BULKS_DATA (example)
