I think you can use merge..
SQL>  merge into portal_log p
  2   using (select sysdate dt from dual) s
  3   on (TRUNC(p.logtime) =trunc(s.dt))
  4   when matched then
  5     UPDATE SET counter = counter + 1
  6   when not matched then
  7      INSERT (logtime,counter)
  8     VALUES(sysdate,   1)
  9  /
1 row merged.
