How to use order by and Limit in Spring Data JPA using QueryDSL

Question

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.

Answer 1

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.

Answer 2

如何使用MIN和MAX功能来实现这一目标。

SELECT MAX(objDate) FROM Object
