cubrid_execute($conn"CREATE TABLE foo(a int AUTO_INCREMENT, b set(int), c sequence(int), d char(10))");
cubrid_execute($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($req1CUBRID_CURSOR_FIRST);
$oid cubrid_current_oid($req);

$attr cubrid_col_get($conn$oid"c");
var_dump($attr);

cubrid_seq_drop($conn$oid"c"4);

$attr cubrid_col_get($conn$oid"c");
var_dump($attr);

cubrid_close_request($req);
cubrid_disconnect($conn);
?>
