Hi All. My poor english doest not allow me to get a better subject.
Here is the thing: I have a function who returns a two column result,
that is is used inside another function, like this
CREATE FUNCTION show_result((some args), OUT shoe varchar, OUT desc
varchar , OUT price numeric)
...
as
$$
select shoe,
(get_desc_and_price(shoe)).desc,
(get_desc_and_price(shoe)).price
from ...
$$ language sql;
This is the only way i get this thing working. According to the timming,
it looks like get_desc_and_price() is being called twice. There is some
syntax for calling get_desc_and_price only once?
As getting the 'description' and the 'price' share most of the logic, it
looks ok to write a single function that does the job.
Thanks!
Gerardo
