hello!!!
postgres 7.3.b4
for example：
**************************
drop function plproc_proc1_func(int, int);
drop view plproc_proc1_view;
create view plproc_proc1_view(p1, p2) as select cast(null as int), cast(null as int);
create function plproc_proc1_func(int, int) returns plproc_proc1_view as '
declare
ret record;
-- declare the params
p1 alias for $1; p2 int;
begin
p2 := p1 + 100;
-- set output
select p1, p2 into ret;
return ret;
end;
'language 'plpgsql';
**************************
Now, the example the same as “
create procedure proc1(p1 in int, p2 out int)
begin
p2:=p1+100;
end
”
The function “plproc_proc1_func(int, int)” can return more values by this way!!
I want to know whether can return more values needn't create view or table!
