Hibernate can't define null parameters in jpql with Postgres

Question

I made some method in a Spring Data repository. The idea is to make each parameter optional (or nullable).

 @Query("SELECT lp FROM LicensePlatformEntity lp WHERE " +
        "(:ownerId is null or lp.ownerCompanyId = :ownerId) AND " +
        "(:assignedCompanyId is null or lp.assignedCompanyId = :assignedCompanyId) AND " +
        "(:assignedUserId is null or lp.assignedUser.id = :assignedUserId) AND " +
        "(:isAssigned is null or lp.assignedCompanyAcceptedLicense = :isAssigned)")
List<LicensePlatformEntity> findAllByFollowing(UUID ownerId, UUID assignedCompanyId, UUID assignedUserId, Boolean isAssigned);

It works perfectly well on the H2 in memory database, but PostgreSQL throws an exception, and claims that it can't define parameter %1 or any other which passed with null value. The next step is to apply pagination, so currently it works with CriteriaBuilder but it has no good pagination solutions, not based on offset limit.

How to make optional parameter search suitable for PostgreSQL with out of the box pagination solution, which is not verbose extendable and Spring stack based? Appreciate any help!

There was some attempt of explicit casting of parameters to hibernate types, with full type references, it looks horrible. And also spoils Intellij query processing, which is not useless thing.

This JPA Query to handle NULL parameter value does not have any useful information. Please think before claiming a duplicate.

Answer 1

You can do this by two way:

1. Writing 16 possible method considering all corner cases.
2. Use Specifications like:

You can refer my specification(I know it is totally different)

    public static Specification<Post> search(String keyword) {
        return ((root, criteriaQuery, criteriaBuilder) -> {
            criteriaQuery.distinct(true);
            if (keyword == null) {
                return null;
            }
            return criteriaBuilder.or(
                    criteriaBuilder.like(root.get("title"), "%" + keyword + "%"),
                    criteriaBuilder.like(root.get("content"), "%" + keyword + "%"),
                    criteriaBuilder.like(root.get("excerpt"), "%" + keyword + "%"),
                    criteriaBuilder.equal(root.join("author").get("name"), keyword),
                    criteriaBuilder.equal(root.join("tags").get("name"), keyword.trim().toUpperCase())
            );
        });
    }

     public Page<Post> findAllPostWithFilters(int pageNo, int pageSize, String sortField, String order,
                                             String keyword, List<Long> tids, List<Long> uids,
                                             Date starDate, Date endDate) {
        return postRepository.findAll(PostSpecification.search(keyword)
                        .and(PostSpecification.filterPostByTagIdList(tids))
                        .and(PostSpecification.filterPostByAuthorIdList(uids))
                        .and(PostSpecification.filterPostAfter(starDate))
                        .and(PostSpecification.filterPostBefore(endDate)),
                PostSpecification.getPageable(pageNo, pageSize, sortField, order));
    }
