Re: Question about copy from with timestamp format

[Murali M <manips2002@xxxxxxxxx>]

How do I specify that when I use copy from? this is what I am trying right now..

copy myTable (myTimeCol, col2) from myFile delimiter as '\t'

I am not sure how to specify the time format..

thanks, murali.

Hi,

I wanted to copy a file from local file system to postgres. I have
timestamp value specified as:
YYYYMMDDHH24 format -- for example:
2015072913 -- is July 29, 2015 at 13:00

how do I import this data into a timestamp field?

thanks, murali.

PS: I believe if I need the hour, I need to use timestamp (I do not want
to put the hour as a separate column). I believe date datatype does not
work, if I am right??

test=# create table ts_test(ts_fld timestamp);
CREATE TABLE

test=# insert into ts_test values (to_timestamp('2015072913', 'YYYYMMDDHH24'));
INSERT 0 1

test=# select * from ts_test ;
       ts_fld
