Question

使用spring-boot-starter-data-jpa（版本2.0.4.RELEASE）和PostgreSQL（版本9.5.10），我一直得到 PSQLException ：查询未返回任何结果，尽管我确实按照许多其他人的建议使用了@Modifying。有人建议添加@Transactional也没有什么不同。分析一下StackTrace，可以看到org.postgresql.jdbc.PgPreparedStatement.executeQuery()被调用，而org.postgresql.jdbc.PgPreparedStatement.executeUpdate()应该被调用。我该怎么办？

@Repository
public interface Rank extends JpaRepository<RankArticle, String> {

@Modifying
@Query(value = "UPDATE rank SET id=calc.id, shop_id=calc.shop_id, " +
                "score=calc.score, rank = calc.rank FROM " +
                    "(SELECT id, shop_id, SUM(sales) AS score, CAST(NULL AS INT) AS rank " +
                    "FROM " +
                        "(SELECT id, sales, shop_id FROM daily_pod " +
                        "WHERE shop_id = :shopId " +
                        "UNION " +
                        "SELECT id, sales, shop_id FROM weekly_pod " +
                        "WHERE shop_id = :shopId " +
                        "UNION " +
                        "SELECT id, sales, shop_id FROM end_pod " +
                        "WHERE shop_id = :shopId) " +
                    "AS pods " +
                    "GROUP BY id, shop_id ORDER BY score DESC limit :limit) as calc;"
        , nativeQuery = true)
void calcScore(@Param("shopId") Integer shopId,
               @Param("limit") Integer limit);

}

编辑：添加完整堆栈跟踪：

设法通过将语句更改为INSERT INTO ... ON CONFLICT（...）做一个更新来使它起作用：

IServiceProvider

}

使用@Query和@Modifying
