Hello,
I want to insert data into a column "timestamp without time zone" data
type. The problem is I am receiving the data in UNIX time.
How can I create a trigger to transform the time from UNIX to timestamp
without time zone every time a new record is inserted into my database?
to_timesstamp will take the epoch, which I assume is what you are
talking about, and turn it into a timestamp with time zone. Don't worry
about the timezone.
test=> select to_timestamp(extract(epoch from now()));
to_timestamp
-------------------------------
2014-06-06 06:27:20.484509-07
(1 row)
test=> \d timestamp_test
Table "public.timestamp_test"
Column | Type | Modifiers
--------+-----------------------------+-----------
id | integer |
ts | timestamp without time zone |
ts_z | timestamp with time zone |
Inserting a timestamp with time zone into a field that is timestamp
without timezone will strip the timezone automatically.
test=> insert into timestamp_test values (1, to_timestamp(extract(epoch
from now())), to_timestamp(extract(epoch from now())));
INSERT 0 1
test=> select * from timestamp_test ;
id | ts | ts_z
----+----------------------------+-------------------------------
1 | 2014-06-06 06:30:58.080158 | 2014-06-06 06:30:58.080158-07
(1 row)
So you just need to wrap the above in a function and call it from your
trigger.
Thank you in advance.
Regards,
Alberto.
