Does the oracle order by clause preserve the sequence of the duplicate items

 Hi,

create my_table (id number primary key, name varchar2(80))

/

insert into my_table(1,'smith');

insert into my_table(2,'leon');

insert into my_table(3, 'leon');

Now assuming I issue the following sql:

select * from my_table order by name;

My question is: the sequence of row 2 and row 3 is fixed or not whenever I issued the same query?

Thank you very much
