Create a type. Something like
create type my_type as (i1 integer, t1 text); -- whatever fields you
need
create or replace function test ()
returns my_type as $$
declare
mt my_type%rowtype;
icol integer;
t2 some_table2%rowtype;
begin
select into icol integer_col from some_table1 where some_col =
some_val;
select into t2 * from some_table2 where some_col = some_val;
mt.i1 := icol;
mt.t1 := t2.text_col;
return mt;
end;
$$ language plpgsql;
And you can return multiple my_type records (a set returning
function) by changing the return type to "setof my_type" and then
returning multiple records from your function.
