I think I can only do this is I have the parks_table key in the parks_address table.
One other option, as Nabil suggested, is to have the foreign key the other way round.
Ie. the parks_address key in the parks_table.
Using Nabil's suggestion I wouldn't be able to cascade the delete into the parks_address table.
Thus leaving a lonely address.
So far I think we have discussed 3 solid and sensible options which are all correct SQL possibilities.
I'm just trying to get clear in my head which is the best for this senario.
Thanks
Rudi.
