Use the following: Replace A2 with your table name and put your column names in the select list:

select id, name
from
(
select m.*, rownum r from A2 m
)
where r in
(select round(dbms_random.value(1,(select count(*) from A2))) from user_tables
where rownum < 6)
0

Sujith,

Thanks for your reply.
dbms_random gives me this error: ERROR at line 1:
ORA-00904: : invalid identifier

Looks like this is not initialized. What can /shall I do to start using this package ?

Thanks
