Presto SQL / Athena: select between times across different days

问题

I have a database that contains a series of events and their timestamp.

I find myself needing to select all events that happen between 11:00 and 11:10 and 21:00 and 21:05, for all days.

So what I would do is I extract from timestamp the hour and the minute, and:

SELECT *
 WHERE (hour = 11 AND minute <= 10)
    OR (hour = 21 AND minute <= 05)

However, I was wondering if there's a simpler / less verbose way to do this, such as when you query between dates:

SELECT *
 WHERE date BETWEEN '2020-07-01' AND '2020-07-05'

I read here that this is doable in SQLite, I was wondering if it's possible to be done in presto as well. I've looked at the docs but couldn't find an analogue function that does what time() does in SQLite.

回答1:

You could use date formatting functions, e.g. date_format, then string comparisons:

select *
from mytable
where 
       date_format(mydate, '%H:%i') between '11:00' and '11:09'
    or date_format(mydate, '%H:%i') between '21:00' and '21:04'
    

Note that I substracted one minute from the upper bound, since I assume you don't want to include the last minute. between '11:00' and '11:09' gives you everything from 11:00:00 to 11:09:59.
