To skip a record in a cursor and continue with the next record you can try below code in oracle or sql.
declare
cursor cur1 is select * from emp;
rec cur1%rowtype;
begin
open cur1;
loop
fetch cur1 into rec;
dbms_output.put_line(rec.ename||' '||rec.sal);
fetch cur1 into rec;
exit when cur1%notfound;
end loop;
close cur1;
end;
