【问题描述】：

您好，我有以下问题，我需要在 JpaRepository 中编写一个 @Query 来返回交易列表。我当前的查询如下所示：

@Query("SELECT t FROM Transaction t WHERE t.property IN :property AND (t.createdAt BETWEEN :dateFrom AND :dateTo) GROUP BY t.transactionType")
    List<Transaction> getAllByPropertyAndDatesBetweenGroupedByTransactionType(@Param("property")List<Property> property, @Param("dateFrom") Date dateFrom, @Param("dateTo") Date dateTo);

这里传递的所有参数都是有效的，但我得到错误：

"exception": "org.springframework.dao.InvalidDataAccessResourceUsageException",
    "message": "could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet",

当我正确指定所有内容时为什么会出现此错误？

【问题讨论】：

  • 为什么需要 GROUP BY 子句来获取交易列表？ GROUP BY 应该用于聚合函数，例如 SUM、COUNT、MIN、MAX 等。
  • 为什么不查看生成的 SQL（在 JPA 提供程序日志中）并查看未设置参数的原因？显然，您必须通过 Springs 抽象来了解实际发生的情况，但那是您的选择。 @TinoMThomas GROUP BY 与问题无关...... FWIW。
  • 如果您需要有关 JPA 的任何帮助，您可以从本文档中获得帮助，它将为您提供有关 @query 和本机查询的详细说明，还将帮助您了解 Spring data JPA - docs.spring.io/spring-data/jpa/docs/1.5.0.RELEASE/reference/…

【解决方案1】：

在这里，在您的查询中，您将 Array List 作为没有意义的参数传递，因为 ArrayList 可以包含重复数据。所以我更喜欢 Set 而不是 ArrayList，你可以使用参数的序号而不是 @Param 注释。

@Query("SELECT t FROM Transaction t WHERE t.property IN (?1) AND t.createdAt BETWEEN ?2 AND ?3 GROUP BY t.transactionType")
List<Transaction> getAllByPropertyAndDatesBetweenGroupedByTransactionType(Set<Property> property, Date dateFrom, Date dateTo);

【讨论】：

    【解决方案2】：

    当您编写自定义 SQL 查询以从存储库中获取结果时，它会返回 List 或 array 或 Object 而不是 List&lt;YourClass/Entity&gt;。

    因此，在您的情况下，当您使用 getAllByPropertyAndDatesBetweenGroupedByTransactionType() 方法时，该方法的返回类型将是 List&lt;Object[]&gt; 而不是 List&lt;Transaction&gt;。

    然后，您可以迭代List&lt;Object[]&gt;并根据需要处理每个元素。
