Subject M:M question
Date Mon, 23 May 2005 05:26:09 GMT

Could you advise as to how to better solve the problem.
There is th table M:M with the following structure
     CLASS    FK number ,
     PROPERTY FK number ,
     QUANTITY number .

In my application I define PROPERTY & QUANTITY for the CLASS class (with the
help of checkbox ) upon which I need to record the information/results. If I
choose checkbox - the record is to be deleted, if it is not there - it
should be added, if it is there QUANTITY should be updated.
