Two databases.
Two EOModels, one for each database.
A to-one relationship from an entity in one model to an entity in
the other.
An EOQualifier is built from a search form that includes attributes
on both entities (each in different models.) The destination key
path is entered as "relationshipName.attributeName."
The SQL generated for the qualifier references both tables as if
they were in the same DB (this is Oracle 9i using OraclePlugin, WO
5.3.)
Which blows up since of course the tables aren't in the same view/DB.
You shouldn't necessarily have to write your own SQL, but you will
have to prevent EOF from generating SQL that joins entities in
different DB's as you've discovered. Instead, you'll need ask EOF to
fetch from the join entity(s) in one DB and do the join in your Java
code by fetching from the join entity(s) in the other DB based on the
objects fetched from the first DB.
