My sql is rusty, so I'll let Liz & Larry talk about that. My concern is
with your design.
It seems like your Alias table has columns other than just an alias key
pointing back to the Locality table, like Alias Post Code. This doesn't
seem correct - Locality should be the only place for those fields. If a
user wants to specify their own Alias Locality, have them add 2 rows, 1
to Locality and one to Alias.
This would then solve your 'where can I get the Post Code from' issue.
