> It would be usefull that the JDO Query Langage could do some UPDATE and DELETE on Persistent Object like this :
> UPDATE [<candidate-class>] SET item1=<newValue>, item2=<newValue> [WHERE <filter>]
> The new_value specified for an update operation must be compatible in type with the state-field to
> which it is assigned.
> Bulk Update must modify the value of the version column and refresh Level1 and Level2 cache.
> DELETE FROM [<candidate-class>] [WHERE <filter>]
> By default Bulk Delete is appy on the specified class and its subclasses and doesn't do cascade delete.
> A keyword like CASCADE must be set if we want to does a cascade delete : 
> DELETE CASCADE FROM [<candidate-class>] [WHERE <filter>]
