sql - Retrieve upcoming birthdays in Postgres -


i have users table dob (date of birth) field, in postgres database.

i want write query retrieve next 5 upcoming birthdays. think following needs considered -

  • sorting date of birth won't work because years can different.
  • you want result sorted date/month, starting today. so, example, yesterday's date last row.
  • ideally, without functions. not deal breaker though.

similar questions have been asked on so, most don't have accepted answer. thank you.

you can @ day of year of dob , compare against current date's doy:

select doy     , extract(doy dob) - extract(doy current_date) upcoming_bday users extract(doy dob) - extract(doy current_date) >= 0 order 2  limit 5
