我想获取介于两个时间戳之间的记录。我想要使用hibernate模式。我尝试使用以下查询进行操作,但未获得任何输出
HQL = "From AddressInfo address where address.addressId = '"+newValues.get("pickupAddress").toString()+"' and address.updatedDateAndTime between date_format('" + DateUtility.getTimeOfBeforeOneMinute() + "', '%m/%d/%y %H:%i:%s') and date_format('"+DateUtility.getCurrentDate()+"','%m/%d/%y %H:%i:%s')";
这是从控制台形成的SQL查询:
select addressinf0_.T_ADM_NPK_ADDRESS_ID as T1_5_, addressinf0_.T_ADM_VNM_USER_ID as T2_5_, addressinf0_.T_ADM_FPK_USER_ASSIGNED_ID as T3_5_, addressinf0_.T_ADM_VNM_STREET_1 as T4_5_, addressinf0_.T_ADM_VNM_STREET_2 as T5_5_, addressinf0_.T_ADM_VNM_STREET_3 as T6_5_, addressinf0_.T_ADM_VNM_CITY as T7_5_, addressinf0_.T_ADM_VNM_STATE as T8_5_, addressinf0_.T_ADM_VNM_ZIPCODE as T9_5_, addressinf0_.T_ADM_DNM_LATITUDE as T10_5_, addressinf0_.T_ADM_DNM_LONGITUDE as T11_5_, addressinf0_.T_ADM_TNM_CREATE_DATETIME as T12_5_, addressinf0_.T_ADM_TNM_UPDATE_DATETIME as T13_5_ from t_address_master addressinf0_ where addressinf0_.T_ADM_NPK_ADDRESS_ID='19' and (addressinf0_.T_ADM_TNM_UPDATE_DATETIME between date_format('Tue Oct 02 17:09:53 EDT 2012', '%m/%d/%y %H:%i:%s') and date_format('Tue Oct 02 17:10:53 EDT 2012', '%m/%d/%y %H:%i:%s'))
我的数据库具有T_ADM_TNM_UPDATE_DATETIME = 10/2/2012 5:10:40 PM的记录
但是结果集无法获取此查询…我不知道我哪里出错了。
谁能指导我进一步
您应该使用HQL参数而不是串联。
举个例子:
Map<String, Object> parameterNameAndValues = new HashMap<String, Object>(); Date startDate; Date endDate; // Assign values to startDate and endDate parameterNameAndValues.put("startDate", startDate); parameterNameAndValues.put("endDate", endDate); String hqlQuery = "FROM EntityName WHERE fechaInicio BETWEEN :startDate AND :endDate"; Query query = this.sessionFactory.getCurrentSession().createQuery(hqlQuery); for (Entry<String, Object> e : parameterNameAndValues.entrySet()) { query.setParameter(e.getKey(), e.getValue()); } return query.list();
这将绑定日期参数,并且hibernate将为您进行必要的转换,以避免完整性检查和错误。请记住,即使MySQL以这种格式保存Date对象,其他数据库也可能不会保存,它将破坏Hibernate帮助。
