[jira] [Comment Edited] (JDO-652) Provision of a typesafe refactor-friendly query capability for JDOQL
[ https://issues.apache.org/jira/browse/JDO-652?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=14735201#comment-14735201 ] Andy Jefferson edited comment on JDO-652 at 9/8/15 5:53 PM: What remains on this issue : 1. spec : I don't mind contributing some text. The problem is that most of Ch14 is based around javax.jdo.Query. What I suggest would be updates to 14.1 to mention about JDOQLTypedQuery, an update to Ch14.5 to add the newJDOQLTypedQuery() method. Then insert a new section 14.10 before "Examples" to discuss solely the JDOQLTypedQuery interface. Finally update the "Examples" section to add some examples at the end. Other ideas? Alternately put the new section after examples, and have its examples inline with the various method descriptions. 2. tck : this needs tests. I am not the best person to write these since I've written the majority of the API, and the implementation.

Spec update is in SVN as is this test. Any more to do? otherwise mark as

> When a user goes to the trouble of creating a query to retrieve some
> information it is a common enough scenario that this will need to be
> performed again during the application lifetime. Being able to save a query
> (once created) as a named query (in the PMF) would mean that applications can
> skip the generation step off for subsequent runs.
> Suggested API change would be to add a single method to Query.
> Query q = pm1.newQuery("SELECT p FROM Person p WHERE firstName == :param");
> q.saveAsNamedQuery("PeopleWithName");
> q.execute("John");
> ... (some time later)
> Query q = pm2.newNamedQuery(Person.class, "PeopleWithName");
> q.execute("Brian");
