получить неизвестную ошибку при попытке выполнить длинный запрос в NodeJs с помощью модуля mssql

/ 21 ноября 2018

Когда я пытаюсь выполнить длинный запрос, используя NodeJs mssql@4.2.2, по какой-то причине я получаю неизвестную ошибку, не уверенную, если это так, потому что запрос использует UNION для объединения результатов из другой аналогичной таблицы с такими же именами столбцовили что.Когда я использую тот же код sqlHelper.js для запуска других коротких запросов из тех же таблиц, и он работает нормально, как, например, выполнение чего-то такого:

Select * from tblMenuVerticalLevel0

Все таблицы имеют одинаковую схему, и я добавил схему ниже.Также я хочу отметить, что когда я выполняю тот же запрос с использованием SQL Studio, он работает нормально, нет уверенности, что nodejs даже не будет выполняться, я ставлю точку останова в Visual Studio на строке после того, как запрос был добавлен в память в sqlQuery.переменной, затем скопировал и вставил его в sql studio, запустил его и возвращает результат, не уверенный, почему модуль nodejs mssql не выполнит его, кто-нибудь знает, почему это происходит?
