I have a function that's working for what I needed it to do, but now I need to call it for every id in a different table... and I'm not sure what the syntax should be.
Here is an example:
create or replace function test(uid integer, out vhrs integer, out phrs integer, out fhrs integer) returns setof record as $$ begin vhrs := uid + 1; phrs := uid + 2; fhrs := uid + 3; return next; end; $$ language 'plpgsql';
I currently use it once, I know the id, and just call:
select * from test(42);
all is well.
But now I need to call it for every record in my employee table.
I tried:
select id, vhrs, phrs, fhrs from employee, test(id)
I also tried an inner join, but neither work. Any hints how I might do this?
# select id, test(id) from ids; id | test ----+--------- 1 | (2,3,4) 2 | (3,4,5) 3 | (4,5,6) (3 rows)
is this what you want? if not, maybe # select id, (select vhrs from test(id)) as vhrs, (select phrs from test(id)) as phrs, (select fhrs from test(id)) as fhrs from ids;
