Hello,
I would like to know if the function of with in this project is correct
with q as (select ‘1-quiz’ as stage, count(distinct user_id)
from quiz
‘1-quiz’ this column never exist in quiz table. In with clause, can I create new column ?
I got this query from codecademy you tube video. This is question 6.
What I know is that after Select only existing column list can come
select ( column_list ) from (table).
Thanks,
jinny
