JPA 和 Oracle DB：分页的不同查询导致错误：ORA-00909：参数数量无效

Question

我正在运行一个带有 oracle 数据库的 spring 后端。 我使用规范 API 来执行查询：

@Slf4j
public class ContentSpecification implements Specification<Content> {

  private final transient ContentFilter filter;

  public ContentSpecification(final ContentFilter filter) {
    this.filter = filter;
  }

  @Override
  public Predicate toPredicate(
      @NonNull final Root<Content> root,
      @NonNull final CriteriaQuery<?> query,
      @NonNull final CriteriaBuilder builder) {
    final List<Predicate> predicates = new ArrayList<>();

    if (!isEmpty(filter.getTerm())) {
      // ... not relevant

      predicates.add(builder.or(title, subtitle, body, keywords));
    }
    
    query.distinct(true);

    return builder.and(predicates.toArray(new Predicate[0]));
  }
}

  public PagedModel<ContentModel> getContent(
      final String term,
      final Integer page,
      final Integer size) {

    final int pageSize = size == 0 ? MAX_VALUE : size;

    return pagedAssembler
        .toModel(
            repository.findAll(
                new ContentSpecification(
                    new ContentFilter(term)),
                PageRequest.of(page, pageSize)),
            contentAssembler);
  }

这与 H2 和 MySQL 数据库完美配合。 但是一旦我使用 Oracle 数据库，它就无法工作：

spring:
  datasource:
    driver-class-name: oracle.jdbc.OracleDriver
    initialization-mode: never
    url: <url>
    username: <user>
    password: <pw>
  jpa:
    database-platform: org.hibernate.dialect.Oracle12cDialect
    hibernate:
      ddl-auto: validate
    properties:
      hibernate:
        format_sql: true
        current_session_context_class: org.springframework.orm.hibernate5.SpringSessionContext
    show-sql: true

我得到的控制台输出如下：

只要我删除了 distinct 或 pagination，它也可以与 oracle db 一起使用。

oracle 有没有解决方案让分页和分页一起运行？

所以看来 oracle 的计数查询失败了。 只是为了比较，用H2下面的sql是 生成：

Hibernate: 
    select
        distinct content0_.id as id2_3_,
        content0_.version as version3_3_,
        content0_.status as status9_3_,
        content0_.status_date as status_10_3_,
        content0_.subtitle as subtitl11_3_,
        content0_.title as title12_3_,
    from
        content content0_ 
    where
        content0_.status=? limit ?
Hibernate: 
    select
        distinct count(distinct (content0_.id,
        content0_.version)) as col_0_0_ 
    from
        content content0_ 
    where
        content0_.status=?

Answer 1

错误ORA-00909: invalid number of arguments的原因是提供行数的语句

select
        distinct count(distinct content0_.id,
        content0_.version) as col_0_0_ 
    from
        content content0_
...

COUNT(DISTINCT expr,[expr...]) 可能允许这种构造 MySQL

但在 Oracle 中是非法。

由于您的方言是Oracle12cDialect，我怀疑在实体中有多个标识列的情况下，该方言的实现存在问题 。参见例如here 获取正确的 SQL 解决方案。

还请注意，此查询中的第一个 DISTINCT 是可能的，但完全不相关 作为带有count 的查询将只产生一行-

话虽如此，您应该 IMO 在您的数据模型中做出一些努力，这将使distinct 的使用没有必要。恕我直言，正确方法。

Answer 2

实际上是失败的查询：

    select
        distinct count(distinct (content0_.id,
        content0_.version)) as col_0_0_ 
    from
        content content0_ 
    where
        content0_.status=? ```

是一个查询 spring-data 问题以获得可用记录的总量（请检查：org.springframework.data.jpa.repository.support.SimpleJpaRepository#executeCountQuery - 实际上，提供完整的堆栈跟踪是值得的） .并且您的 Content 实体似乎具有复合 PK，即 (id, version)（同样，未提供实体定义），但 HBN 在此类查询中遇到了一些困难：https://hibernate.atlassian.net/browse/HHH-11042
