Something just feels wrong here with Ted's code.

postingsForMonth sounds like a multiple (to-many) relationship. But
if "objectIDPostingsForMonth is a foreign key", that would be a to-
one relationship. Pierre's code is correct for a to-one
relationship. It feels like you are modelling things wrong or naming
them in a confusing manner.

I forgot to mention that "objectIDPostingsForMonth" is a foreign
key and the relationship in the entity Posting is called
"postingsForMonth"

a more elegant way of trying to fetch null objects?
Currently I have an object 'Posting' with a fetch spec
'fetchNullPostingForMonth' with the qualifier
'(objectIDPostingsForMonth = nil)'
Then in my code I have:
NSArray results =
EOUtilities.objectsWithFetchSpecificationAndBindings( ec,
"Posting", "fetchNullPostingForMonth", null);
To me this seems crude, but it does work. Is there a better way
though?
