I ran a query without the column alias and seems that Oracle names that
column with the entire name for ex: "sum(foo)". If that is true the
support could be completed.
I'll try it when get some free time or if some kind guy could send the
output of this:
$db = DB::connect("oci8://...");
print_r($db->getRow("select count(somefield) from table",
DB_FETCHMODE_ASSOC));
here, would be so great :-)
