you could solev your problem if you add an integr random number colum to your table like this
alter yourtable add column(yourRndColumn integer)
update yourtable set yourRndColumn = Rnd() * 20
the last step
select * from yourtable
where yourRndColumn = 1
instead of 1 you could also put a any other random numbers.
so you will select randomly 5% of
