Vim tells me there is a closing parenthesis missing from this
statement. :-)

If the number of addresses and phone numbers is not known, this approach
won't work. I think SQL won't work at all here. I'd say the requirement
is wrong.

You could concatenate all the address and phone records in a parseable
string representation, but it feels wrong as well.
