I'm trying to write a function that can do a select on an integer value
from a table and subtract that value from current_timestamp.
Let's say I have a table called users and a field called tz_offset..
I want my function to do something like :
select current_timestamp - '( select tz_offset from users where userid =
? ) hours'::interval
Obviously this syntax is incorrect, but I'm not quite sure how to do the
subquery and make the integer result of it part of the quoted interval
expression.
Any tips?
Thx

ok, sorry to reply to my own message, but I figured out a way:
select current_timestamp - ( select tz_offset from users where userid = ? ) * '1
hour'::interval;
