I have had to convert a couple of derived (keyword-based) queries into corresponding native ones (Postgres sql) and I have noticed the ORDER BY clause does not seem to work. Here are two sample queries:


After a number of tests I came to the conclusion that native queries do not seem to handle well ORDER BY clauses and this causes an issue with my current application. Is there any way to handle them with native queries? Any potential alternative? I would also be happy with converting them back to derived queries.

Thank you

Avoid native queries when possible. JPQL is not only database-independent, but also the query optimizer is less likely to provide the performance benefits that JPA can give to its own language. Besides which it's a lot easier to code for table joins!

Having said that, I don't see anything wrong with the SQL you've got working just fine under PostgreSQL. It might not be handled as deftly as a JPQL query would be by JPA, but PostgreSQL definitely knows how to order JOIN results.
