将日期参数传递给本机查询 [英] Pass date parameter to native query

问题描述

用户可以根据出现值执行操作.当此值等于DAILY"时，我想检索过去 24 小时内未完成的所有日常操作.

A user can perform actions based on an occurrence value. When this value is equal to 'DAILY', I would like to retrieve all daily actions that have not been completed the last 24 hours.

有效的 SQL 查询:

The working SQL query:

SELECT distinct a.* FROM action as a LEFT OUTER JOIN history as h
ON a.id = h.action_id
AND h.user_id= <user> WHERE a.occurrence = 'DAILY' AND (h.id is NULL OR h.entry_date < TIMESTAMP 'yesterday')

等效的原生查询:

@Query(value = 
        "SELECT distinct a.* FROM action a "
        + "LEFT OUTER JOIN history h "
        + "ON a.id = h.action_id "
        + "AND h.user_id = :userId "
        + "WHERE a.occurrence='DAILY' AND (h.id IS NULL OR h.entry_date < :yesterday) ", nativeQuery = true)
public List<Action> findAllAvailableActions(@Param("userId") Long userId, @Param("yesterday") ZonedDateTime yesterday);

如何在我的服务中调用它:

How it is called in my service :

ZonedDateTime today = ZonedDateTime.now(ZoneOffset.UTC);
ZonedDateTime yesterday = today.minus(1,ChronoUnit.DAYS);
Long userId = userDTO.getId();
List<Action> result = actionRepositoryCustom.findAllAvailableActions(userId, yesterday);

但是，我在测试中确实得到了错误的结果(返回已完成的操作).恐怕这与日期参数有关.属性 entry_date 在我的实体中声明为 ZoneDateTime.我做错了什么?

However, I do get the wrong results in my tests (actions that have already been completed are returned). I am afraid this is linked to the date parameter. The attribute entry_date is declared as ZoneDateTime in my entity. What am I doing wrong ?

推荐答案

您不能将 ZonedDateTime 传递到本机 SQL 查询中.您需要将其转换为日历:

You can't pass a ZonedDateTime into a native SQL query. You need to convert it to Calendar:

@Query(value = 
    "SELECT distinct a.* FROM action a "
    + "LEFT OUTER JOIN history h "
    + "ON a.id = h.action_id "
    + "AND h.user_id = :userId "
    + "WHERE a.occurrence='DAILY' AND (h.id IS NULL OR h.entry_date < :yesterday)", nativeQuery = true)
public List<Action> findAllAvailableActions(@Param("userId") Long userId, @Param("yesterday") Calendar yesterday);

您可以通过这种方式转换 ZonedDateTime:

And you can convert your ZonedDateTime this way:

public Calendar convertToDatabaseColumn(ZonedDateTime entityAttribute) {
    if (entityAttribute == null) {
        return null;
    }

    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(entityAttribute.toInstant().toEpochMilli());
    calendar.setTimeZone(TimeZone.getTimeZone(entityAttribute.getZone()));
    return calendar;
}
