I have 2 columns in my google sheet - Time, and some Ids
My aim is to calculate the number of ids reported in an hour. For example, from this image we can tell from 10AM to 11AM - 4 ids, and from 11AM to 12PM - 5 ids. I want to come up with a QUERY Function ONLY that helps me do so, and group the number of IDs hour-wise. Any help would be much appreciated.
use:
=QUERY(QUERY(A2:B,
"select hour(A),count(B) where B is not null group by hour(A)"),
"offset 1", )
