我试图使用我在我的类中进行的查询来检索某些数据。 我在Oracle SQL Developer上试过这个查询,它工作正常,我从这个查询中得到了结果。 但是当我尝试使用它throught的Java返回我一个错误:使用Hibernate在java中创建查询:无法解析属性
无法getFlightInSandbox:无法解析属性:tacticalplanning_id的:com.atosorigin.airbus.evpt.model.Flight [选择f.id来自com.atosorigin.airbus.evpt.model.Flight f,其中f.isinsandbox ='Y'和f.tacticalplanning_id in(选择id来计划其中的域如'R%')和((f.id in(select c。 flight_id from changelog c其中c.logactiontype_id in(从logactiontype l中选择l.id,其中l.key ='APC7CREATE')))或(f.id in(从ca.logactiontype中选择ca.flight_id ca.logactiontype_id in(select l .id from logactiontype l where l.key ='APC7CREATE'))))and f.id not in(从task中选择flight_id,其中name ='---- APC7 UPD ----')]

我不知道createSQLQuery存在!我通过使用我的类的属性名称而不是DB列的名称来解决我的问题。但也许那个createSQLQuery也可以工作:) – Majestic
这是另一种选择,类属性是HQL期望的,如果你已经映射或注释为实体,显然。 – malaguna
@Majestic我会感谢你,如果你接受或投票我的答案,因为它似乎对你有帮助 – malaguna
