It sounds like the FK column is defined as NOT NULL. Can you just
drop that constraint, or recreate the table without it?

I am working with a database that for whatever reason won't allow a
foreign key to be null if the relationship does not exist. I am unable
to make any changes to the database setup. In this database table A may
have an optional one-one relationship with table B. If there is not
relationship or I delete a relationship, WO wants to set the foreign key
in table A for table B to null. The database won't allow the foreign
key column of table A to be null it wants it to be 0. Is there an easy
trick to get WO to generate 0 instead of null for that key if the
relationship does not exist?
