Postgresql: Select between dates + time

Good morning. In the movement table, I have, among others, the date and time fields. I need to select between the chosen date and the following day (Ex.: between 09/11/2020 and 09/12/2020). I need the select Filtre between '07:00' of the day 11/09/2020 and '07:00' of the day 12/09/2020, informing the movements 24 hours.

Between dates, manually informing, ok:

select * from movimento
WHERE '[2020-09-11, 2020-09-12]'::daterange @> data
order by data,hora

However, I would like, tbm, to automatically pick up the day after the first informed day. In addition to the time filters. To know: In the system, the time is entered manually during the registration as it can be done outside the current time.

Postgresql in particular provides the following special date values (date and timestamp): today, tomorrow and yesterday considering, for timestamp, the time (00:00).

Assuming your date and time fields are of the type date and time use: WHERE (data+hora) - INTERVAL '7 HOUR' BETWEEN 'today'::timestamp AND 'tomorrow'::timestamp;

I assumed that data be the type date and hora of the kind time. Here is a test: bdteste=# SELECT '2020-09-11 12:00:00'::TIMESTAMP - INTERVAL '7 HOUR' BETWEEN 'today'::timestamp AND 'tomorrow'::timestamp;
 ?column? 
----------
 t
(1 row)

Thanks anonymity. I did as you suggest, but the return brings all the records. I need all records to appear between the chosen date (09/11/2020) and your time (set at 07:00:00 in the morning) and your next day (09/12/2020 07:00:00). Totaling 24 hours of movements.

My test worked as expected: SELECT * FROM (VALUES ('2020-09-09', '10:00'), ('2020-09-10', '03:00'), ('2020-09-11', '12:00'), ('2020-09-12', '05:00'), ('2020-09-12', '18:00')) AS t(data, hora) WHERE (data::DATE + hora::TIME) - INTERVAL '7 HOUR' BETWEEN 'today'::timestamp AND 'tomorrow'::timestamp;
 data | hora 
------------+-------
 2020-09-11 | 12:00
 2020-09-12 | 05:00
(2 rows)

Hello,

From what I understand, you give a date from which you want the interval of 24h (or 1) day after the chosen time.

Try to use the interval:

select * 
from movimentos
where true 
-- obeservar que o valor da data '2020-09-11 07:00:00' deve vir de alguma variável que é utilizada duas vezes
and (data + hora)::timestamp between '2020-09-11 07:00:00' and ('2020-09-11 07:00:00'::timestamp + interval '1 day')
order by
data,
hora

Take a look here too. Example

Here is everything that postgresql offers in relation to this Documentation
