this is exactly what I was looking for :-))) Thank you very much indeed!
I'd been trying various combinations without getting the right one ...
Now a few words for Duncan, Peter and Andreas:
I've a table recording purchases and sales of different items (could be
stocks, shares, car-parts, or whatever you want). Foor each item there
is a negotiation date, an initial price, a quantity, a current price and so on.
What I was looking for was a summary table showing the effective
quantity of the item I'm holding to-date, besides a few other data, and
Richard's solution does give that.
I know that the other data might be inaccurate: to get their
correct value I should devise a different general design for my database
(which I already have in OOo-Calc), may be a table for each item, and a
way to connect the various tables according to the desired target. But
this is only a sort of 'first aid' table ...
I hope to have clarified you doubts.
Thanks again to all of you for your help.
Regards,
Ennio.
