Выбрать несколько столбцов в подзапросе после предложения where

Question

Я пытаюсь сравнить значение в один столбец с несколькими значениями в столбце, рядом с тем, где нижеприведенный пункт - моя проблема, как будто я хочу получить данные из пользовательских отделов 4 (IT_Infrase c) & 10 (финансы ), пожалуйста, научите меня, он говорит, что подзапрос должен иметь только один столбец, но я не знаю, как его решить

SELECT * FROM

Answer 1

where dept_id in 
              (SELECT IT_Infrasec FROM mobile_access
               INNER JOIN users 
               ON users.id = mobile_access.userID 
              WHERE users.username = 'username')

Примечание. В подзапросе предложения IN следует использовать только 1 столбец.

Answer 2

Что не нравится mysql

where dept_id in 
              (SELECT IT_Infrasec,Finance,Management,Business FROM mobile_access
               INNER JOIN users 
               ON users.id = mobile_access.userID 
              WHERE users.username = 'username'

Ваш выбор возвращает 4 столбца, но допускается только один столбец.

Я не знаю, какой из них имеет требуемый dept_id, но вам нужно сгенерировать запрос, который возвращает только один столбец

Like

SELECT ID FROM mobile_access
