Ответ на Re: Return type for procedure  ("Jaime Casanova" <systemguards@gmail.com>)

Hi Jaime,
thanks for your reply.
 
Could anyone check if this is correct for what I'm trying to do
 

CREATE FUNCTION test(id integer,name varchar,date_start date date_end date) RETURNS record as $$
$$ language 'your-language';
 
if id="1" then
select * from tblemployee;
elseif id="2" then
select client_name,address
from tblclients;
endif

and then execute the function as

select * from test() as (report1, report2)
 
would this work? This is just example code for select statements which are far much longer
 
Cheers,
Ben

yes.

just create your functions as:

CREATE FUNCTION test() RETURNS record as $$
$$ language 'your-language';

then execute the function as

select * from test() as (field1 type1, field2 type2...);
