Can anyone help me to figure out how to write a query to do contains
(Key) in JDO? Here is my scriplet:
select from " + master.class.getName()
+ " where detailKeySet.contains('" + detail.getKey().toString() + "')"
where detailKeySet is a Set<Key> collection holding all the keys of
the details for the master.
I ran it in GAE and it doesn't return anything even though I do have
the deailKeySet populated with detail.getKey(). Please help, thanks a
lot in advance.
