Oracle – ‘CONTINUE’ keyword in Oracle 10g PL/SQL

continueoracle

I'm migrating a TSQL stored procedure to PL/SQL and have encountered a problem – the lack of a CONTINUE keyword in Oracle 10g.

I've read that Oracle 11g has this as a new feature, but upgrading is not an option unfortunately.

Is there any alternative to CONTINUE in 10g? I don't believe it's practical to restructure the logic of the SP as a work-around, because I have an outer loop, an IF, then a nested IF, then the CONTINUE at the end of a statement block within that IF.

Any help would be greatly appreciated, cheers.

You can simulate a continue using goto and labels.

DECLARE
   done  BOOLEAN;
BEGIN
   FOR i IN 1..50 LOOP
      IF done THEN
         GOTO end_loop;
      END IF;
   <<end_loop>>  -- not allowed unless an executable statement follows
   NULL; -- add NULL statement to avoid error
   END LOOP;  -- raises an error without the previous NULL
END;
