To be clear: This is RelStorage 1.5.0 running against Oracle RAC 10g. I tried changing the line in question (relstorage/adapters/schema.py line 895) to "TRUNCATE TABLE %s" % table, and the following error is generated: ORA-02266: unique/primary keys in table referenced by enabled foreign keys So I guess without a bunch of work it will not be possible. regards, Darryl Dixon Winterhouse Consulting Ltd http://www.winterhouseconsulting.com _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org https://mail.zope.org/mailman/listinfo/zodb-dev
