Michael Bouschen commented on JDO-652:
--------------------------------------
@[~andy]:
The tck class SampleQueries include all the sample queries from chapter "14.10
Examples" of the spec.
I started to implement a JDOQLTypedQuery version of all the sample queries. But
I ran into issues for three queries:
testQuery15f and testQuery16f both fail with the message "Cannot call
executeResultList method when query has result unset. Call executeList
instead.". Both queries try to store the result into a warpper class, but I hve
no idea how to specify this with an JDOQLTypedQuery.
testQuery19f uses a correlated subquery and I think we need an API extension
for this, see JDO-778.
Please take a look at branch JDO-652 on github to see my current version of
class SampleQueries. Here the link:

> There are various querying capabilities of this type around. JPA2 has its
> Criteria query API. Third party solutions like QueryDSL also exist, in its
> case providing a JDOQL implementation (as well as JPQL, and HQL). We should
> seriously consider introducing something along these lines in the JDO2.4
> timeframe.
