Spring Data and Native Query with pagination
My apologies in advance, this is pretty much summing up the original question and the comment from Janar, however...
I run into the same problem: I found the Example 50 of Spring Data as the solution for my need of having a native query with pagination but Spring was complaining on startup that I could not use pagination with native queries.
I just wanted to report that I managed to run successfully the native query I needed, using pagination, with the following code:
@Query(value="SELECT a.* "
+ "FROM author a left outer join mappable_natural_person p on a.id = p.provenance_id "
+ "WHERE p.update_time is null OR (p.provenance_name='biblio_db' and a.update_time>p.update_time)"
+ "ORDER BY a.id \n#pageable\n",
/*countQuery="SELECT count(a.*) "
+ "FROM author a left outer join mappable_natural_person p on a.id = p.provenance_id "
+ "WHERE p.update_time is null OR (p.provenance_name='biblio_db' and a.update_time>p.update_time) \n#pageable\n",*/
nativeQuery=true)
public List<Author> findAuthorsUpdatedAndNew(Pageable pageable);
The countQuery (that is commented out in the code block) is needed to use Page<Author>
as the return type of the query, the newlines around the "#pageable" comment are needed to avoid the runtime error on the number of expected parameters (workaround of the workaround). I hope this bug will be fixed soon...
This is a hack for program using Spring Data JPA before Version 2.0.4.
Code has worked with PostgreSQL and MySQL :
public interface UserRepository extends JpaRepository<User, Long> {
@Query(value = "SELECT * FROM USERS WHERE LASTNAME = ?1 ORDER BY ?#{#pageable}",
countQuery = "SELECT count(*) FROM USERS WHERE LASTNAME = ?1",
nativeQuery = true)
Page<User> findByLastname(String lastname, Pageable pageable);
}
ORDER BY ?#{#pageable}
is for Pageable
.
countQuery
is for Page<User>
.
Just for the record, using H2 as testing database, and MySQL at runtime, this approach works (example is newest object in group):
@Query(value = "SELECT t.* FROM t LEFT JOIN t AS t_newer " +
"ON t.object_id = t_newer.object_id AND t.id < t_newer.id AND o_newer.user_id IN (:user_ids) " +
"WHERE t_newer.id IS NULL AND t.user_id IN (:user_ids) " +
"ORDER BY t.id DESC \n-- #pageable\n",
countQuery = "SELECT COUNT(1) FROM t WHERE t.user_id IN (:user_ids) GROUP BY t.object_id, t.user_id",
nativeQuery = true)
Page<T> findByUserIdInGroupByObjectId(@Param("user_ids") Set<Integer> userIds, Pageable pageable);
Spring Data JPA 1.10.5, H2 1.4.194, MySQL Community Server 5.7.11-log (innodb_version 5.7.11).
Try this:
public interface UserRepository extends JpaRepository<User, Long> {
@Query(value = "SELECT * FROM USERS WHERE LASTNAME = ?1 ORDER BY /*#pageable*/",
countQuery = "SELECT count(*) FROM USERS WHERE LASTNAME = ?1",
nativeQuery = true)
Page<User> findByLastname(String lastname, Pageable pageable);
}
("/* */"
for Oracle notation
)
I have exact same symptom like @Lasneyx. My workaround for Postgres native query
@Query(value = "select * from users where user_type in (:userTypes) and user_context='abc'--#pageable\n", nativeQuery = true)
List<User> getUsersByTypes(@Param("userTypes") List<String> userTypes, Pageable pageable);
