Hi

eZEvent uses cascading deletes which is not supported by our db schema classes.
This causes several problems:

• db consistency check will not work
• not possibly to change db engine from mysql to oracle
• Breaks test system (makes teamroom not testable )

  Steps to reproduce

  In extension/ezevent/sql/mysql/ezevent.sql you have the following:

    -- CONSTRAINT FOREIGN KEY ( parent_event_id ) REFERENCES ezevent( id ) --
    -- ON DELETE CASCADE --
