Question

我是JPA2.0和Spring Data JPA的新手，我尝试在其中获取详细信息where createdDt > Sysdate and createdDt > sysdate-1。我不确定是否可以使用CURRENT_DATE-1函数来实现sysdate-1，但无法正常工作。

以下选项的任何帮助都无法正常工作吗？我也尝试过YESTERDAY，但这也失败了。

此处，我不希望使用PersistanceContext和实体管理器查询进行开发。

@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();

下面的错误

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，某些实现（并非全部！）支持功能，例如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。但这是提取月份中的某天，不确定是您想要的。

如果要引用“昨天”，则可以尝试使用CURRENT_DATE-1，但这不是可移植的（某些DB可以接受，而其他则不行）。

您可以尝试：

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

但是也许您需要在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);

在服务端：

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

CURRENT_DATE-1的JPQL查询不起作用
