My application contains both ORM and OGM. For ORM I was wrote some named queries in xyz.hbm.xml. But while using OGM those queries caused for exception. I am using OGM 4.1.3.Final version. Please help someone.

OGM is for NoSQL databases, so I wonder how do you want to run some named queries from the Hibernate ORM legacy configuration?

1. Are you planning to use both a relational database and a NoSQL store?
2. Why don't you use the JPA persistence.xml for configuring OGM?

Hi,

Can you share the exact exception you get and the queries you are trying to run? What Hibernate OGM backend are you using? Is this about named *JP-QL/HQL* or *SQL* queries? The former should work with Hibernate OGM to some degree (e.g. simple SELECTs), whereas the latter naturally don't work as our current backends don't support SQL as a query language.

Querying is work-in-progress in general, so it'd be valuable to know what you are after. You might also send in a pull request to enhance our experimental parser (which translates JP-QL into native NoSQL queries such as MongoDB's CLI query syntax or Neo4j's Cypher language) so it supports the things you are after. An alternative is to use Hibernate Search which will create a separate Lucene index, allowing to run queries against it and fetch result entities from the underlying NoSQL store.

Cheers,

--Gunnar
