maybe it's a silly question but I cannot find the answer in the docs: How can set a limit to the CriteriaQuery using JPA2?
Thanks
JPA Setup In our repository method, we use the EntityManager to create a Query on which we call the setMaxResults() method. This call to Query#setMaxResults will eventually result in the limit statement appended to the generated SQL: select passenger0_.id as id1_15_, passenger0_.
JPQL does not provide a mechanism to limit queries. This is most often achieved by using the setMaxResults() method on the Query . If you must avoid specifying this in Java code, you could make a view in the database that contains your query and performs the limit.
The limit keyword is used to limit the number of rows returned in a query result.
public interface CriteriaBuilder. Used to construct criteria queries, compound selections, expressions, predicates, orderings. Note that Predicate is used instead of Expression<Boolean> in this API in order to work around the fact that Java generics are not compatible with varags. Since: Java Persistence 2.0.
A CriteriaQuery is not an executable Query. You need to create a TypedQuery first using EntityManager.createQuery(criteriaQuery)
. You can then set the max results of this and execute it.
