I donīt belive it. There are indeed different behaviours regarding the
proprietary outer joins from Oracle and the ANSI SQL standard. Thanks
for
the advice to test the ANSI style. This one returnes the right result
without
bringing the server down. (Problem described a few posts before.)
More over, the ANSI style executes 2 times faster. On the other side
there
seem to be a bug in the proprietary outer join processing of Oracle.
Now everything looks fine. I do once more thank all the people who
assisted
and helped me with their advices and knowledge on this topic.
Regards
Roman
