how to convert integer minutes to interval in postgres
Fastest way is with make_interval
make_interval(years int DEFAULT 0, months int DEFAULT 0, weeks int DEFAULT 0, days int DEFAULT 0, hours int DEFAULT 0, mins int DEFAULT 0, secs double precision DEFAULT 0.0)So it looks like this (as suggested by @Teddy)
SELECT make_interval(mins => 20);or,
SELECT make_interval(0,0,0,0,0,20);Not to say that's the cleanest, if speed isn't an issue I prefer the * method @a_horse_with_no_name mentioned
SELECT 20 * '1 minute'::interval;
you can concat that integer with ' minutes':
t=# with i as ( select 20::int n)select concat(n,' minutes')::interval from i; concat---------- 00:20:00(1 row)Time: 1.220 msUpdate:
Or: interval '1' minute * n as a_horse_with_no_name says
In the case you are trying to insert data in an interval column, you can use integer seconds and PostgreSQL will convert it to a interval.
