In JDO, I'm trying to get all the ImportVendor entities that are children of
a specific ImportSession entity, which has a Set<ImportVendor>. I want to
page through them using query cursors. I've tried the following, based on
the docs:
Query children = pm.newQuery(ImportedVendor.class);
children.setFilter("parent-pk == keyParam");
children.declareParameters("Long keyParam");
List<ImportedVendor> vendors = (List<ImportedVendor>)
children.execute(page.getSession().getId());
I get an UnspportedDatastoreOperatorException saying that AppEngine doesn't
support the "-" operator.
What am I doing wrong?
At
http://code.google.com/appengine/docs/java/datastore/transactions.html#Uses_For_Transactions,
there's this snippet:
query = pm.newQuery("select from Account " +
"where parent-pk == keyParam " +
"parameters Key keyParam");
Does this snippet actually work? I feel like I'm doing exactly the same
thing, and getting an exception. How do I specify a parent key in a query?
