Now i realize how it is possible (i made it tens of times in databases programs :-). But i feel it ab-normal. I must extract data from a "natural" container to put it in an artificial one which can be useful only in some rare cases and I must duplicate at least one value to keep the link with the "master" db and add a ID for every record. It is the prize of relational row/column struct. It has the advantage of a direct access to the data of the derived db. I'm starting ask if it is the best path to follow. --- Ciao Romano -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with "unsubscribe" in the subject, without the quotes.
