我是sql server的新手,想在java和sql server之间建立连接.我的连接代码是:
public static void main(String[] args) {
Connection con;
try {
String connectionUrl = "jdbc:sqlserver://HELLO-PC:1433; databaseName=Attendance Teachers;";
con = DriverManager.getConnection(connectionUrl, "", "");
System.out.println("connected");
java.sql.Statement st = con.createStatement();
}
catch (SQLException ex) {
Logger.getLogger(AttendanceTeachers.class.getName()).log(Level.SEVERE, null, ex);
}
我的服务器名称是'HELLO-PC',我也添加了sqljdbc.jar.我看到错误:
Feb 01, 2013 11:24:46 AM attendance.teachers.AttendanceTeachers main
SEVERE: null
java.sql.SQLException: No suitable driver found for jdbc:sqlserver://HELLO-PC:1433; databaseName=Attendance Teachers;
at java.sql.DriverManager.getConnection(DriverManager.java:604)
at java.sql.DriverManager.getConnection(DriverManager.java:221)
at attendance.teachers.AttendanceTeachers.main(AttendanceTeachers.java:30)
我真的需要帮助.谢谢.
我需要从URL发送参数到cakephp控制器.我有两个参数'ufrom'和'uto'的消息表.在控制器中我想将此值保存在消息表中.
我输入了网址:
http://localhost/ar/messages/add?ufrom=9&uto=3
在MessagesController我有功能:
public function add() {
if(($this->request->query['uto'])and($this->request->query['ufrom'])){
$this->Message->create();
if ($this->Message->save($this->request->data)) {
$this->set('addMessage',TRUE);
$this->set('ufrom',$this->request->query['ufrom']);
$this->set('uto',$this->request->query['uto']);
$this->redirect(array('action' => 'index'));
} else {
$this->Session->setFlash(__('The message could not be saved. Please, try again.'));
}
$targets = $this->Message->Target->find('list');
$this->set(compact('targets'));
}
else{
$this->set('error',true);
}
}
在add.ctp我有:
<?php
if(isset($error)){
echo('error');
}
else{
echo json_encode($ufrom);
echo json_encode($uto);
echo json_encode($addMessage);
}
?>
但是当我使用上面的URL时,我看到:
Notice (8): Undefined variable: ufrom [APP\View\Messages\add.ctp, line 6]null
Notice (8): Undefined variable: uto [APP\View\Messages\add.ctp, line 7]null
Notice (8): Undefined variable: addMessage [APP\View\Messages\add.ctp, line 8]null …我有一个提交按钮，我需要从左到右扫过它的背景：
<input type="submit" value="Send Request" class="sweep">
我需要像扫描到正确的过渡之类的东西。所有示例都用于button 、 a 、 li 和 Div标签。
