Linking Tables
I have a device table that has a mix of devices, by that I mean some IP devices that have a mac address and some that do not.
I have another table "IP Addresses" that have a row for each IP device (has a mac address that is unique)
If I have in the "DECICE TABLE" rows with a null value for the "mac address field)
which will have no entry in the IP Address" table
the primary key for the "IP Address" table is the mac address
how can I make this work
