JPA自定义查询从多个表中删除

Question

我有一个自定义查询，用于从2个表中删除记录，如下所示

@Repository
public interface RoamingStatusHistoryRepository extends JpaRepository<RoamingStatusHistory, String> {
    @Query("DELETE rsh,rs from RoamingStatusHistory rsh inner join RoamingStatus rs on rsh.msisdn = rs.msisdn where TIMEDIFF(NOW(),rsh.createdDate)>'00:00:30'")
    public List<Date> deleteByDate();
}

但是在删除IntelliJ说出预期中得到了rsh 之后，并且在rsh之后出现了一个错误，说出别名定义或期望中得到了'，'

如何解决此问题。在互联网上进行了研究，但找不到解决方法

我假设此查询是本机SQL查询，所以您必须添加nativeQuery = true

@Repository
public interface RoamingStatusHistoryRepository extends JpaRepository<RoamingStatusHistory, String> {

    @Query("DELETE rsh,rs from RoamingStatusHistory rsh inner join RoamingStatus rs on rsh.msisdn = rs.msisdn where TIMEDIFF(NOW(),rsh.createdDate)>'00:00:30'",
           nativeQuery = true)
    public List<Date> deleteByDate();
}
