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.
