org.apache.openjpa.jdbc.sql.Row.whereForeignKey()
Set the foreign key equality criteria to link to the given object. If the related type uses table-per-class mappings, the foreign key may be targeted at an independent superclass table.

                // maybe some other field already is updating?
                row = rm.getRow(getTable(), Row.ACTION_UPDATE, sm, false);
                if (row == null) {
                    Row del = rm.getRow(getTable(), Row.ACTION_DELETE, sm,
                        true);
                    del.whereForeignKey(_fk, sm);
                }
