Question

我在JPA存储库中有此查询：

@Repository
public interface PaymentTransactionsDailyFactsRepository extends JpaRepository<PaymentTransactionsDailyFacts, Integer> {

    @Query(value = "SELECT " + 
            " COUNT(*) count, " + 
            " SUM(amount) volume, " + 
            " DATE(created_at) date, " + 
            " YEAR(created_at) year, " + 
            " MONTH(created_at) month, " + 
            " WEEK(created_at) week, " + 
            " DAY(created_at) day, " + 
            " type transaction_type, " + 
            " contract_id, merchant_id, terminal_id, " + 
            " status, card_brand, currency " + 
            " FROM payment_transactions " + 
            " WHERE status NOT IN ('pending_async','pending','pending_review','in_progress','new') AND created_at BETWEEN :start_date AND :end_date " + 
            " GROUP by date, contract_id, merchant_id, terminal_id, transaction_type, status, card_brand, currency", nativeQuery = true)
    List<PaymentTransactionsDailyFacts> generateDailyFacts(@Param("start_date") LocalDate start_date, @Param("end_date") LocalDate end_date);
}

但是当我在Spring Scheduler中执行它时，出现错误：

SQL Error: 1054, SQLState: 42S22
Caused by: java.sql.SQLSyntaxErrorException: No such column: id

当我在MariaDB中执行此查询时，它工作正常：

SELECT  COUNT(*) count,  SUM(amount) volume,  DATE(created_at) date,  YEAR(created_at) year,  MONTH(created_at) month,  WEEK(created_at) week,  DAY(created_at) day,  type transaction_type,  contract_id, merchant_id, terminal_id,  status, card_brand, currency  FROM payment_transactions  WHERE status NOT IN ('pending_async','pending','pending_review','in_progress','new') AND created_at BETWEEN '2011-04-11 00:00:01' AND '2029-04-11 00:00:00'  GROUP by date, contract_id, merchant_id, terminal_id, transaction_type, status, card_brand, currency

如您所见，我正在为表payment_transactions运行此本机查询，但是我期望表payment_transactions_daily_facts的结果。有没有办法正确实施此查询？

尝试在查询中添加id

@Query(value = "SELECT " + 
            " id," + 
            " COUNT(*) count, " + 
            " SUM(amount) volume, " + 
            " DATE(created_at) date, " + 
            " YEAR(created_at) year, " + 
            " MONTH(created_at) month, " + 
            " WEEK(created_at) week, " + 
            " DAY(created_at) day, " + 
            " type transaction_type, " + 
            " contract_id, merchant_id, terminal_id, " + 
            " status, card_brand, currency " + 
            " FROM payment_transactions " + 
            " WHERE status NOT IN ('pending_async','pending','pending_review','in_progress','new') AND created_at BETWEEN :start_date AND :end_date " + 
            " GROUP by date, contract_id, merchant_id, terminal_id, transaction_type, status, card_brand, currency", nativeQuery = true)
    List<PaymentTransactionsDailyFacts> generateDailyFacts(@Param("start_date") LocalDate start_date, @Param("end_date") LocalDate end_date);

如果您要获取给定PaymentTransactionsDailyFacts和start_date之间的所有end_date实体，而它们的status不是（'pending_async'，'pending'， 'pending_review'，'in_progress'，'new'），则可以使用以下查询。

@Query(value = "SELECT * " 
            " FROM payment_transactions " + 
            " WHERE status NOT IN ('pending_async','pending','pending_review','in_progress','new') AND created_at BETWEEN :start_date AND :end_date " + 
            " GROUP by date, contract_id, merchant_id, terminal_id, transaction_type, status, card_brand, currency", nativeQuery = true)

但是，由于您在查询中使用了group by，因此您似乎正在尝试获取一些汇总数据，而不仅仅是获取满足条件的PaymentTransactionsDailyFacts实体的列表。如果真是这样，那么您做错了所有。您必须使用投影。

更新：使用投影

首先在项目中某处的下面创建一个界面。您应该根据需要调整退货类型。

public interface PtdsDTO {
    Integer getCount();
    BigDecimal getVolume();
    LocalDate getDate();
    Short getYear();
    Short getMonth();
    Short getWeek();
    Short getDay();
    String getTransactionType();
    Integer getContactId();
    Integer getMerchantId();
    Integer getTerminalId();
    String getStatus();
    String getCardBrand();
    String getCurrency();
}

然后，在相应存储库的顶部导入该接口。

将存储库的返回类型更改为List<PtdsDTO>。

List<PtdsDTO> generateDailyFacts(@Param("start_date") LocalDate start_date, @Param("end_date") LocalDate end_date);

就这样。

从JPA存储库中的另一个表中选择数据
