In JPQL, the LIMIT clause is not directly supported. Mar 26, 2025 · Limiting query results in JPA is slightly different from SQL; we don’t include the limit keyword directly into our JPQL. 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. Then map an entity to this view as you would a table. . This is most often achieved by using the setMaxResults() method on the Query. One common use case is to limit the number of results returned by a query. Instead, you can achieve similar functionality using the setMaxResults () and setFirstResult () methods provided by the JPA criteria query. setParameter(arg0, arg1) . example: public interface ProductRepo Jun 21, 2024 · Remember to tailor result limits to meet specific application needs while prioritizing performance optimization.
