Subject [jira] Commented: (JDO-652) Provision of a statically-typed refactor-friendly query capability for JDOQL
Date Fri, 02 Jul 2010 03:04:50 GMT

    [ https://issues.apache.org/jira/browse/JDO-652?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12884520#action_12884520
] 

Matthew T. Adams commented on JDO-652:
--------------------------------------

@Timo:  The code examples that I would propose look similar to what they do in JPA2 criteria
queries, except the replacement of field name strings with the newly proposed syntax and appropriate
modifications in the spirit of JDO collection navigation vs. JPA's "join" syntax.  Depending
on the design of JDO's query api, it may or may not be verbose.

> 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.
