Hello, I've moved my database from SQLite into Java DB using SQLWrapper. I expected the references integrity constraint, to cascade on update. I.e. wColumn in refTable, references expColumn in expTable. Updating expColumn should update wColumn. However I get: java.sql.SQLIntegrityConstraintViolationException: UPDATE on table 'EXPRESSIONS' caused a violation of foreign key constraint 'SQL100315193342610' for key (la testa). The statement has been rolled back.
The only reference I found, seems to suggest for UPDATE it's not possible to cascade. Is that the case? http://db.apache.org/derby/docs/10.5/ref/ -- Regards, K.
