qt5.4做数据库插入时报Parameter count mismatch  问题

qt5.4做数据库插入时报Parameter count mismatch  问题  请问大家是什么原因， 下面是插入代码：

QSqlQuery  query;
     query.prepare("INSERT INTO stu(id, name, address) VALUES (:id, :name, :address)");
     query.bindValue(":id",ui->idLineEdit->text().toInt());
     query.bindValue(":name",ui->nameLineEdit->text());
     query.bindValue(":address",ui->addressLineEdit->text());
     //query.bindValue(":pickname",ui->pickNameLineEdit->text());
    bool  ok= query.exec();
    if(ok)
    {
        qDebug()<<"insert  database  Success";
        ui->idLineEdit->clear();
        ui->nameLineEdit->clear();
        ui->addressLineEdit->clear();
        //ui->pickNameLineEdit->clear();
    }
    else
      {
                  qDebug()<<"error  Message:"<<query.lastError().text();
    }
运行就会报 Parameter count mismatch
