запрос не возвращает никаких результатов в Python

Question

Часть кода SQL работает в моем SQL, когда %s заменяется желаемым временем начала.Я попробовал все, и кажется, что я не могу получить результаты в Python - возвращаемое значение [].

Я пытался переписать WHERE from (Convert_TZ(Tablex, 'TZ1', 'TZ2') Between 'Time1' and 'time2', так как я не видел, чтобы запросы использовали междув питоне раньше.

Все работает как положено, но ничего не возвращается в US_results (просто печатается в консоли как []), а в файле excel есть только заголовки.
