Corroborate if a .sqlite file exists in a folder

Julian

Hello.

How to know that a ".sqlite" file exits on the folder? For example if "intersection.sqlite" do not exist in the folder I have to do something and if it do not exist do another thing.

What I had do is:


      QSqlDatabase *ultima;
      ultima=new QSqlDatabase();
      ultima->addDatabase("QSQLITE", "twelve_connection");
      ultima->setDatabaseName(ui->lineEdit_interseccion->text().remove(" ")+".sqlite"); //this is the name of sqlite's file

        if(ultima->isOpen())
        {

        crearTablaFallasNuevas();
        }
        else
        {
        agregarTablaFallasNuevas();
        }
        delete ultima ;

But for what I see QSqlDatabase::isOpen just compare if ultima run, because it always goes to crearTablaFallasNuevas()

Hi
Its best to use QFileInfo as as far as I remember, the SQL open will create new db if not there.

bool fileExists(QString path) {
    QFileInfo check_file(path);
    // check if file exists and if yes: Is it really a file and no directory?
    if (check_file.exists() && check_file.isFile()) {
        return true;
    } else {
        return false;
    }
}
