Sådan tilføjer du antal dage i postgresql datetime

Dette vil give dig fristen :

select id,  
       title,
       created_at + interval '1' day * claim_window as deadline
from projects

Alternativt funktionen make_interval kan bruges:

select id,  
       title,
       created_at + make_interval(days => claim_window) as deadline
from projects

For at få alle projekter, hvor deadline er overstået, skal du bruge:

select *
from (
  select id, 
         created_at + interval '1' day * claim_window as deadline
  from projects
) t
where localtimestamp at time zone 'UTC' > deadline
