    Return the row to use for this field. This method is meant only for single-value fields that might reside in a table that is joined to the primary table through the join foreign key. It is not meant for multi-valued fields like collections and maps. The method checks whether we're using an outer join and if so it deletes the field's previous value, then if the field is non-null returns an insert row for the new value. The join foreign key will already be set on the returned row; mapping strategies just need to set their own values. Utility method for use by mapping strategies.
