I would use ROWNUM for this,
-- To get ODD numbers
SELECT rn + 1 FROM
(Select rownum rn from table_name
Where rownum <= 10)
WHERE mod(rn, 2) = 0;
-- To get EVEN numbers
SELECT rn FROM
(Select rownum rn from table_name
Where rownum <= 10)
WHERE mod(rn, 2) = 0;
P.S You could use any table in your schema, but make sure that it has enough number of rows in there as per your Where condition(Where rownum <= 10). In this case you should have atleast 10 rows to see the results correctly.
Thx,
SriDHAR
