Question

我正在尝试确定移动用户的当前位置。我在表格中有经度和经度以及时间戳＆＃34; Mobilelocations＆＃34;。

编写以下JPQL查询，以便从＆＃34; MobileLocations＆＃34;中检索纬度，经度和时间。表。时间选择在晚上9点到早上7点之间。预计

Query query = entityManager.createQuery("SELECT loc FROM MobileLocations loc WHERE CAST(loc.time as time)>= '21:00:00' or CAST(loc.time as time)<='07:00:00'");

但似乎它不能解决这个错误：

java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token: < near line 1, column 212 [SELECT NEW com.vishwas.dto.mobile.MobileLocationsDto (loc.latitude, loc.longitude,loc.time) FROM com.vishwas.entity.mobile.MobileLocations loc where CAST(loc.time as time)>= '21:00:00' or CAST(loc.time as time)=<'07:00:00'

Answer 1

它也可以在不使用强制转换功能的情况下工作。试试这个：

SELECT loc FROM MobileLocations loc WHERE loc.time between '21:00:00 00:00:00' and '07:00:00 00:00:00'

查询以选择超出日期时间的时间范围
