[提问]连接数据库，model->setTable出错 [复制链接]

如题， 利用QSqlTableMode ，插入信息到数据库，在main()已经连接到数据库
Dialog w;    QSqlDatabase db = QSqlDatabase::addDatabase("QODBC");            db.setDatabaseName(QString("DRIVER={SQL SERVER};"                                       "SERVER=%1;"                                       "DATABASE=%2;"                                       "UID=%3;"                                       "PWD=%4;").arg("ACER-PC")                               .arg("integrity")                               .arg("sa")                               .arg("123"));    if(db.open())    {    w.show();    return a.exec();    }    else    {        QMessageBox::information(NULL,"提示","系统载入数据库失败，无法运行",QMessageBox::Yes);    }

    return a.exec();在model->setTable("hashnumber");    if(!model->select())    {        qDebug()<<model->lastError();        return ;    }这里出错QSqlError(-1, "Unable to find table hashnumber", "") 说找不到这张表，但数据库明明有这张表啊

解决了，应该把声明Dialog w放在数据库连接之后
