here is an example ..try and see(it display all prime numbers between 2 and 100
set serveroutput on
declare
begin
for i in 2..100
loop
for j in 2..trunc(sqrt(i))
loop
if mod(i,j)=0 then goto c; end if;
end loop;
dbms_output.put_line(to_char(i));
<<c>> null;
end loop;
end;

is there another way of doing a loop for prime numbers besides taking the square root? No other easier way. Because I have to do prime numbers form 10000 to 10100
