cubrid_execute($conn, "CREATE TABLE foo(a int AUTO_INCREMENT, b set(int), c list(int), d char(10))");
cubrid_execute($conn, "INSERT INTO foo(a, b, c, d) VALUES(1, {1,2,3}, {11,22,33,333}, 'a')");

$req = cubrid_execute($conn, "SELECT * FROM foo", CUBRID_INCLUDE_OID);

cubrid_move_cursor($req, 1, CUBRID_CURSOR_FIRST);
$oid = cubrid_current_oid($req);

$attr = cubrid_col_get($conn, $oid, "b");
var_dump($attr);

cubrid_set_add($conn, $oid, "b", "4");
