Not sure I understand exactly, but if you want to know whether tableA is referenced by any other tables, you can do something like:
tableA_referenced_by = set(field._table for field in db.tableA. _referenced_by) That will give you a set of any tables (the actual DAL Table objects) that have fields referencing tableA (note, I used set() in order to de-duplicate in case a given table has more than one field referencing tableA).
