相关疑难解决方法(0)

我不是Web应用程序的专家,最近我正在使用servlet为我的移动应用程序编写一个小的webapp.我的议程是从客户端接收数据,并将其放入数据库.一切都运行正常,除了我的数据库插入语句,我试图使用PreparedStatement实现.

// This is how my insert statement looks like
private String INSERT_INTO_DEVICES = "INSERT INTO travlemate.devices (owner,"
        + "deviceid,gcmid) VALUES (?,?,?)"; 

// This is how am trying to insert
PreparedStatement preparedStmt = mConn.prepareStatement(INSERT_INTO_DEVICES);
preparedStmt.setString(0, data.getDeviceNumber());
preparedStmt.setString(1, data.getDeviceID());
preparedStmt.setString(2,data.getGcmId());
preparedStmt.execute();
mConn.close();

但在执行此任务时,我收到以下异常

java.sql.SQLException: Parameter index out of range (0 < 1 ).
