sql - Oracle Random Number Generator Stored Procedure without using DBMS_RANDOM -

-

i don't have access dbms_random package, create own stored procedure generate random numbers in oracle. know how might that?

thanks in advance!

edit: trying generate random row each state. code:

select z.* (        select a.*, row_number() on (partition a.state order (           select to_char(systimestamp,'ff') dual)) row_id            state_table ) z z.row_id=1;

it gives me same rows everytime run it, want give me different rows everytime run it. please?

if want select random rows table can use sample clause

select * mytable sample(4);

this gives randomly selected 4% of rows.
