Re: bigint and unix time

Additional information:

If I use the following query:

select "time", extract(epoch from (date 'now' - integer '30')), extract(epoch from (date 'now'))
from ticket_change

The first row looks like this:
Bigint, double precision, double precision
1286090615000000;1310850000;1313442000

Thanks,
Janiv,

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?
