These were my concerns in the first place I was thinking about using
triggers. Maybe I haven't really understood your suggestion right. When
would the temporary table be created? Isn't it neccessary to create it
on every insert, too? With wich statement could I do this without using
a trigger which is fired on every insert?

Thanks for your patience.
