Hibernate: delete from printer_feature where printers_id=? and features_id=? Hibernate: delete from printer_feature where printers_id=? and features_id=? Hibernate: delete from printer_feature where printe
我希望实现deleteAll方法,该方法将删除所有User实体及其关联,同时我希望在获取内存堆中的用户集合时防止java.lang.OutOfMemoryError异常。public void deleteAll() { final int PAGE_NUMBER = 0; List<User> result;
Session session = s

我尝试使用Hibernate HQL查询执行批量删除,但我得到了一个查询语法错误。FROM: delete [ delete from pl.com.bms.avaro.staticData.model.NewCalendarDay ] at org.hibernate.hql.classic.PreprocessingParser.token(PreprocessingParser.j
