Ошибка в Google Data Studio при использовании MySQL в качестве источника данных

/ 04 января 2019

Я сталкиваюсь со следующей проблемой с MySQL в сочетании с Data Studio и, откровенно говоря, совершенно растерялся: 

SELECT 
user.name,
user.second_name,
school.name,
SUM(booked_lessons.duration),
SUM(total_lessons.duration),
SUM(theory_lessons.duration)
FROM
lesson
    LEFT JOIN
user ON lesson.instructor_id = user.id
    LEFT JOIN
school ON lesson.school_id = school.id
    LEFT JOIN
(SELECT 
    lesson.id, lesson.duration
FROM
    lesson
WHERE
    lesson.status = 'active'
        AND entity = 'driving'
        AND lesson.user_id IS NOT NULL) AS booked_lessons ON booked_lessons.id = lesson.id
    LEFT JOIN
(SELECT 
    lesson.id, lesson.duration
FROM
    lesson
WHERE
    lesson.status = 'active'
        AND entity = ('driving' OR 'theory' OR 'exam')) AS total_lessons ON total_lessons.id = lesson.id
    LEFT JOIN
(SELECT 
    lesson.id, lesson.duration
FROM
    lesson
WHERE
    lesson.status = 'active'
        AND entity = 'theory') AS theory_lessons ON theory_lessons.id = lesson.id
WHERE
lesson.startDate >= '2018-01-31 00:00:00'
    AND lesson.startDate <= '2019-01-06 23:59:59'
GROUP BY lesson.instructor_id;`

Когда я включаю импорт кода в качестве источника данных MySQL в Google Data Studio, кажется, все работает нормальновначале.Тем не менее, когда я хочу проанализировать данные в диаграммах, я получаю следующее сообщение об ошибке: Ошибка 1

Еще более запутанным является следующее:

`Код практически идентичен.Но теперь я получаю это сообщение об ошибке:

Ошибка 2

Может кто-нибудь помочь мне здесь?

Заранее спасибо.

Нельзя ставить точку с запятой (;) в конце запроса, поскольку Datastudio добавляет код в запрос при генерации данных.
Была та же проблема, удалил точку с запятой и теперь отчет работает.

) AS t0 GROUP BY Vorname ORDER BY qt_bdgy5cbbub DESC'

У вас есть точка с запятой в конце подзапроса, перед 

") AS t0"?
