It can not sort right if it's column is bigint type.

It can not sort right if it's column is bigint type.
But, int, short is doing well.

1. create table btbl (c bigint);
2.
insert into btbl values (1);
insert into btbl values (2);
insert into btbl values (10);
insert into btbl values (20);
insert into btbl values (100);
commit;
3. select * from btbl;
4. if you click "c" title column on top of the query result, it will sort 1, 10, 100, 2, 20....
5. But, it should be shown as 1, 2, 10, 20, 100.
