I am using Spring Data JPA with a RDBMS in my project. I have a requirement where I have to fetch a single record from the Database from a table which has the latest date. For this I need to use a limit and order by function OR using sub queries. However, I wished to know if i wish for not to use NamedQuery is there a way I can achieve this using Spring Data JPA and QueryDSL.

Shouldn't QueryDslPredicateExecutor.findAll(Predicate predicate, Pageable pageable)
do the trick for you? You could hand in a new PageRequest(0, limit)
and thus would get back the first limit
results.

How about using the MIN and MAX function to attain this.
SELECT MAX(objDate) FROM Object
