So what you want is not what values are greater than some point 30 days ago
which is what your previous query asked and answered, but the values between a
point 30 days ago and today. The easiest way is to use BETWEEN:
test(5432)aklaver=>\d big_int_test
Table "public.big_int_test"
Column | Type | Modifiers
--------+---------+-----------
bint | bigint |
rint | integer |
test(5432)aklaver=>SELECT * from big_int_test ;
bint | rint
------------------+------------
1287323899000000 | 1310799600
test(5432)aklaver=>SELECT
bint
FROM
big_int_test
WHERE
bint
BETWEEN
extract(epoch from (date 'now' - integer '30'))
AND
extract(epoch from (date 'now'));
bint
------
(0 rows)
That being said, if your time values are the order of magnitude shown they will
not meet the criteria above. Is the time value supposed to be seconds?
