RE: Comparing dates in 3.0

Hi Ellen,

Subtracting one timestamp from another returns an interval type, like
this:

stasis=# select 'now'::timestamp - '10 Sep 2000'::timestamp;
  ?column?
-------------
 75 12:06:57
(1 row)

But if you just want the days only, try this:

stasis=# select date_part('days', 'now'::timestamp - '10 Sep
2000'::timestamp);
 date_part
-----------
        75
(1 row)

Hope this helps.

Regards

Francis
