哦 那个忘了贴上了

dao

package gos.hzyg.hdgos.dao.secu;

import java.util.List;

/**

*/
public interface AroomLevelDao {

/**
* 方法 getAllaRoomLevel()
* 查询所有的相关信息
* @param cAreaid

*/
List getAllaRoomLevel();

}

接口实现

package gos.hzyg.hdgos.dao.imp.secu;

}

删除语句
delete from downwater1 where address!='志新小区'

delete from downwater2 where address!='志新小区'

delete from upwater1 where address!='志新小区'

delete from upwater2 where address!='志新小区'

修改属性列
alter table block alter column otherdept varchar(200);
alter table t_politic1 add column content varchar(500);
