I map data from rows in tables to objects in Java. When I map integers
in the database I map them to integer primitives in Java. The challenge
I am running into is what do I do when a table has a integer foreign key
that is null. Ideally when a table in PostgreSql has a foreign key that
does not exist I would like the value to be zero rather than null. This
works really well for me because I NEVER use a key with the value of 0.
Is there some way for me to tell PostgreSql that a zero is the same as
null when using foreign keys that map to integers? That way I can still
use cascade delete. The only way for me to get around this issue is to
remove the foreign key constraint for cascade delete.
Any help would be appreciated.
