I want to use the ORM.
My first go at this did not work, it might have to do with
FB/kinterbasdb as it expects the stored procedures to be called in one
of these ways.
cur.execute("select output1, output2 from the_proc(?, ?)", (input1, input2))
cur.callproc("the_proc", (input1, input2))
I'll spend some more time on this tomorrow.

Pity that the above is not reading "When I am going to ......" :-) .
