如何在Hibernate 3.0中实现mysql date_sub（）函数

您可以使用本机SQL查询

String sql = "SELECt * FROM tablename WHERe created_at > DATE_SUB(curdate(), INTERVAL 7 DAY)"Query query = session.createSQLQuery(sql);List result = query.list();

或者您可以使用Hibernate Criteria
Restrictions.sqlRestriction

String sqlWhere = "{alias}.created_at > DATE_SUB(curdate(), INTERVAL 7 DAY)";Criteria criteria = session.createCriteria(MyEntity.class);criteria.add(Restrictions.sqlRestriction(sqlWhere));List result = criteria.list();

希望能有所帮助。
