hello ...
i have put some research into that some time ago and as far as i have seen
there is a 99% chance that no other database can do it the way we do it. it

oracle: disgusting workaround ...

db2: disgusting workaround (no server side code it seems)
sybase: disgusting workaround (no serverside code it seems)
microsoft: there seems to be something coming out (or just out) but i have not
seen anything working yet.
