是用jbuilder弄了一个框架
jdbc已经连接好了数据库，关于jdbc和数据库的设置应该都设置好了
想获取数据库中某个表的字段值与界面中jtextfiled中的字符串相比较，
定义了一个按钮事件来实现，方法代码如下：
void jButton1_actionPerformed(ActionEvent e) {

String t=queryDataSet1.getString("id");
String t2=queryDataSet1.getString("password");
String s1=jTextField1.getText();
String s2=jTextField2.getText();
if(s1.equals(t) && s2.equals(t2))

jTextField1.setText("jjjkljfo");
其中的queryDataSet的query属性应该设置正确了，但是当我按这个按钮的时候确没有反应
就是说应该是不能读取数据库中某个表的字段值。
希望高手指点
解决了必给加分
谢谢~~~~~~~~~

没反应那是没提交了
把页面代码拿出来啊
光看这个没用吧

不是很懂jbuilder
下面两点可能对你查找原因有帮助：
1.queryDataSet1.setQuery(new com.borland.dx.sql.dataset.QueryDescriptor(database1, "select *\nfrom logo1", null, true, Load.ALL));

queryDataSet1 调用了setQuery方法就能从数据库中拿到数据集了吗？是不是应该有个什么方法让它执行查询

2. String t=queryDataSet1.getString("id");
String t2=queryDataSet1.getString("password");

如果在1的代码中已经取到了数据集，那么你这里调用去字段值的方法拿到的是第几条纪录（如果纪录有多条的话）
