Select from Oracle to MySQL returns only one row

Question

Environment:
The Oracle Developer Days Virtual Box image, so that's 11gR2 EE on OEL
MySQL 5.1.51-community
mysql-connector-odbc-5.1.7-0.i386.rpm
unixODBC 2.3.0
I got the connection working, I can insert, update and delete records in the MySQL DB from Oracle (SQL Plus).
But when I enter select * from "employees"@mysql I only get the first record returned.
If I enter select * from "employees"@mysql order by "id" desc, I only get the last one...
If I enter select count(*) from "employees"@mysql, I get the - correct - result of 3.
So, how do I get the complete set of (all) records from a MySQL table in Oracle? Is there some kind of setting or is this intended behavior and do I have to create a PL/SQL loop and put the results into a collection or something like that?

I've create a table like yours:
create table gateway.employees(id int(10) auto_increment,
first_name varchar(30),
last_name varchar(100),
personal_code varchar(20),
birthday date,
salary decimal(10,2),
is_active int(1),
PRIMARY KEY (id));
insert into gateway.employees (first_name,last_name) values ('Name 1', 'Name 1');
insert into gateway.employees (first_name,last_name) values ('Name 2', 'Name 2');
insert into gateway.employees (first_name,last_name) values ('Name 3', 'Name 3');
insert into gateway.employees (first_name,last_name) values ('Name 4', 'Name 4');
insert into gateway.employees (first_name,last_name) values ('Name 5', 'Name 5');
select * from gateway.employees;
and tested it using DataDirect and MySQL ODBC.
The DataDirect shows all 5 lines whereas MySQL 5.1.0.7 ODBC shows only 1 row.
(isql isn't using extended fetching like DG4ODBC does).

Here the result (fetching ID column):
MySQl ODBC;
SQL> select "id" from "employees"@MYSQL_EMGTW_1121_DB;
id
1
DD ODBC V6:
SQL> select "id" from "employees"@DD60_MYSQL_EMGTW_1121_DB;
id
1
2
3
4
5

The 32bit version of MySQL ODBC (5.1.5 - no 5.1.7 release yet installed) works also:
SQL> select "id" from "employees"@MYSQL_32;
id
1
2
3
4
5
=> so it is an ODBC issue
