spring 中的休眠查询使用 H2 启动：类型 "BOOLEAN" 和 "INTEGER" 的值不可比较

Question

我正在尝试运行自定义查询，但遇到了一个奇怪的（看似无关的）错误。我得到的错误是： o.h.engine.jdbc.spi.SqlExceptionHelper : SQL Error: 90110, SQLState: 90110 Values of types "BOOLEAN" and "INTEGER" are not comparable; SQL statement:

select episode0_.episode_id as episode_1_1_, episode0_.air_date as air_date2_1_, episode0_.episode_number as episode_3_1_, episode0_.name as name4_1_, episode0_.season as season5_1_, episode0_.show_id as show_id7_1_, episode0_.watched as watched6_1_ from episode episode0_ where episode0_.episode_number=(select min(episode1_.episode_number) from episode episode1_ where episode1_.watched=0) and episode0_.season=(select min(episode2_.season) from episode episode2_ where episode2_.watched=0) and episode0_.show_id=? [90110-210]

我尝试过的事情：本机查询，以及这个：

我的存储库：

import model.Episode;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;

import java.util.Optional;

public interface EpisodeRepository extends JpaRepository<Episode, Long> {
    Optional<Episode> findByEpisodeId(Long episodeId);

    @Query("from EPISODE where episodeNumber = (SELECT MIN(episodeNumber) FROM EPISODE WHERE watched is false)" +
            " AND season = (SELECT MIN(season) FROM EPISODE WHERE watched is false) " +
            " AND show.showId = :showId")
    Optional<Episode> findNextUnwatchedEpisode(@Param("showId") Long showId);
}

我的实体：

package model;

import lombok.*;

import javax.persistence.*;
import java.util.Date;

@Data
@NoArgsConstructor
@AllArgsConstructor
@Builder
@ToString
@Entity(name = "EPISODE")
public class Episode {
    @Id
    @Column(name = "EPISODE_ID", nullable = false)
    private Long episodeId;

    @Column(name = "NAME", nullable = false)
    private String name;

    @Column(name = "SEASON", nullable = false)
    private Integer season;

    @Column(name = "EPISODE_NUMBER", nullable = false)
    private Integer episodeNumber;

    @Column(name = "AIR_DATE", nullable = false)
    private Date airDate;

    @Column(name = "WATCHED", nullable = false)
    private boolean watched;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name="SHOW_ID")
    private TVShow show;
}

application.properties:

Answer 1

Hibernate ORM 仅从 5.6.5.Final 版本开始支持 H2 2.x.y。旧版本产生无效的 SQL，新版本的 H2 在默认配置中不接受。

您需要检查您的应用程序使用的 hibernate-core jar 版本并将其更新到某个最新版本（当前版本是 5.6。7.Final）。
