Question

How can I get this Postgres statement to parse into Oracle 11g?

UPDATE teams as new 
  SET counter=old.counter, 
      task_counter=old.task_counter 
FROM teams as old
WHERE new.is_old=0 
  AND old.is_old=1 
  AND new.name=old.name 
  AND new.county=old.county;

Thanks in advance.

UPDATE teams
  SET (counter, task_counter) = (select counter, task_counter 
                                 FROM teams old
                                 WHERE old.is_old = 1 
                                   AND teams.name = old.name   
                                   AND teams.county = old.county)
where is_old = 0

This assumes that the sub-select will only return a single row for each name/county/is_old combination.
