BUG?? Exeption handling brakes a Loop?! (PL/SQL executed by C) Anybody know this ????

Question

(OS - SCO, Oracle 817, Pro*C/C++: Release 2.2.4.0.0)
In C program I have a PL/SQL block with WHILE LOOP. Inside the loop I have SELECT statement with a begin..end arroung it and with EXCEPTION WHEN NO_DATA_FOUND for internal block. In this exception I have no RAISE statement. So, I expect the loop will be not broken by NO_DATA_FOUND error.
After control comes to the EXCEPTION NO_DATA_FOUND the loop is not continue anymore (but error is not populated out of this begin..end.) If EXCEPTION NO_DATA_FOUND is commented by -- the loop runs completely.
Is it known bug? Does anybody get something like this?
To be more specific, my EXEC SQL EXECUTE .. END EXECUTE block looks like this:
DECLARE
BEGIN
WHILE .. LOOP
begin SELECT ...
exception when NO_DATA_FOUND then NULL;
when others then ... RAISE;
end;
END LOOP;
END;
Would appreciate any response on this matter.
Thanks!
Alex.

Call the procedure from another "wrapper" procedure. In the wrapper, place the call within to your existing procedure in a
for i in 1..3 loop
  call procedure;
  if <successful condition> then
    exit loop;
  end if;
end loop;I think that'd be easier than trying to work on controlling everything from within a single procedure. You could even set up a PACKAGE where the wrapper was the only public procedure, where your current procedure is private, and thus, can't be called outside of the wrapper, by accident. --=cf
