本文导语: 这样一个问题:当JList中的选中项目改变时,我要把此记录的所有其它字段取出置于界面控件中,我写了以下代码: public void valueChanged(ListSelectionEvent evt) { String selList=(String)lstylrfwzl.getSelectedValue(); ...
这样一个问题:当JList中的选中项目改变时,我要把此记录的所有其它字段取出置于界面控件中,我写了以下代码:
public void valueChanged(ListSelectionEvent evt)

int selList_fanghao_i=selList.indexOf("号");
String selList_jiequ=selList.substring(0,selList_jiequ_i + 2);
String selList_donghao=selList.substring(selList_jiequ_i + 2,selList_donghao_i);
String selList_fanghao=selList.substring(selList_donghao_i + 1,selList_fanghao_i);
String sql11="select * from weiming.酒钢商业用房基本资料库 where 街区='" + selList_jiequ + "' and 栋号='" + selList_donghao + "' and 房号='" + selList_fanghao + "'";
try

}
}
catch(Exception ex)
{
System.out.println(ex.getMessage());
System.out.println(sql11);
}
}
运行情况是:
房号,建筑面积,租金标准都能显示,但项目列表框一直改变,不断触发此事件时:错误提示为
java.sql.SQLException: [Oracle][ODBC][Ora]ORA-01000: 超出打开光标的最大数。
使用面积 一直出不来。
另外,我把上面的/* */去掉时,什么都出不来

是不是不断触发事件,而没有关掉记录集rs_detail和数据库连接,可加
再加一个finally模块试一试,
即:finally{
try{
//把记录集关闭
if(rs_detail!=null){rs_detail.close();rs_detail=null}
//关闭数据库连接
if(db_jiequ!=null){db_jiequ.close();db_jiequ=null}
}catch(Exception e ){;}
}
