I'd like to compute some "row like" results and return them from a
function (and pass the result to PHP[*]).
Well I've read about composite type but all the references I've seen
are about coding in C. That's not the way I'd like to follow by now.
I was expecting to declare composite types in plpsql or plain sql in a
similar way I'd do in C/C++ with struct/class.
I've found this
http://archives.postgresql.org/pgsql-general/2001-03/msg01459.php
but I'd like to avoid to declare a table just for a temp.
pseudocode follow
declare struct pippo(
integer a;
varchar(8) b;
)
create or replace function functiontest( ) returns pippo
as '
declare
integer tempa;
varchar(8) tempb;
begin
/*
do stuff to fill tempa and tempb
*/
return (tempa,tempb)
end
' language plpgsql;
[*] I guess that to access the result of such a function
...
$SQLResult = pg_exec( $SQLConn, "SELECT functiontest( );" );
$SQLData = pg_fetch_row( $SQLResult, 0 );
should be enough...
thx
