Michael, I did some research. I think that Query Filter Extensions were planed in Kodo but were not implemented. AFAIK big part of Kodo's codebase was at one point donated to OpenJPA. The only extension I've managed to find in the latest docs of OpenJPA is MethodQL.
Other Query Language Extensions besides Filter Extensions were Aggregate Extensions, JDOQL Non-Distinct and JDOQL Subqueries. Do you think that I should make a feature request in OpenJPA's JIRA? -- View this message in context: http://openjpa.208410.n2.nabble.com/openjpa-kernel-using-PostgreSQL-s-inet-operators-in-JPQL-tp7581619p7581764.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
