带有 CURRENT_DATE - 1 的 JPQL 查询不起作用

Question

我是JPA2.0 和Spring Data JPA 的新手，我正在尝试获取详细信息where createdDt > Sysdate and createdDt > sysdate-1。我不确定是否可以使用 CURRENT_DATE-1 函数实现 sysdate-1，它不起作用。

以下选项的任何帮助都不起作用？我也试过YESTERDAY，也失败了。

这里我不打算使用 PersistanceContext 和实体管理器查询来开发。

@Query("SELECT e FROM CustMstr e WHERE e.crteDt < CURRENT_DATE AND (DAYS(e.crteDt) > DAYS(CURRENT_DATE) - 1) AND e.accActive ='Y'")
List<CustMstr> findByEmailAndAcc();

另一种方式

@Query("SELECT e FROM CustMstr e WHERE e.crteDt < CURRENT_DATE AND (DAYS(e.crteDt) > CURRENT_DATE - 1) AND e.accActive ='Y'")
List<CustMstr> findByEmailAndAcc();

以下错误

Answer 1

JPA 将 CURRENT_DATE / CURRENT_TIME / CURRENT_TIMESTAMP 定义为引用当前日期/时间的可移植方式。

此外，一些实现（不是全部！）支持功能，如 year / month / day / hour / minute / second。

在您的代码中，您使用days。您可以将其替换为day。但它是一个提取月份中的一天，不确定它是你想要的。

如果你想引用“昨天”，你可以尝试使用CURRENT_DATE-1，但这不是必须的（有些数据库可以，其他的不行）。

你可以试试：

@Query("SELECT e FROM CustMstr e WHERE e.crteDt between CURRENT_DATE-1 AND  CURRENT_DATE AND e.accActive ='Y'")
List<CustMstr> findByEmailAndAcc();

但也许您需要在 java 端进行管理：

在存储库方面：

@Query("SELECT e FROM CustMstr e WHERE e.crteDt between :start and :end AND e.accActive ='Y'")
List<CustMstr> findByEmailAndAcc(Date start, Date end);

在服务方面：

List<CustMstr> findByEmailAndAcc(){
    Date start=new Date();
    Date end=new Date(date.getTime()-(24*3600));
    return repository.findByEmailAndAcc(start, end);
}
