復制代碼 代碼如下:

#include <QtCore/QCoreApplication>
#include <QSqlDatabase>
#include <QDebug>
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
QSqlDatabase db=QSqlDatabase::addDatabase("QMYSQL");
db.setHostName("localhost");
db.setDatabaseName("study");
db.setUserName("root");
db.setPassword("tyh");
if(!db.open()){
qDebug()<<"Unable to open database";
}else{
qDebug()<<"Database connection established";
}
return a.exec();
}
