Unsolved Use two or more SQLite database at the same time

[Julian]

Hello people I have this compiler's ouput

---

QSqlDatabasePrivate::removeDatabase: connection 'qt_sql_default_connection' is still in use, all queries will cease to work.
QSqlDatabasePrivate::addDatabase: duplicate connection name 'qt_sql_default_connection', old connection removed.

---

It's because I use a database:

    db= QSqlDatabase::addDatabase("QSQLITE");
    db.setDatabaseName(nombre);
    db.open();
    createTablaSemaforos();

And then I need to use other one (That depends on an event )

        fallas= QSqlDatabase::addDatabase("QSQLITE");
        fallas.setDatabaseName(texto);
        fallas.open();


    QString consulta;
    consulta.append("CREATE TABLE IF NOT EXISTS ");
    consulta.push_back(ui->lineEdit_interseccion->text().remove(" "));


    consulta.push_back("(a TEXT primary key, j TEXT);");

    QSqlQuery crear(fallas);
    crear.prepare(consulta);
    crear.exec();

And I never close db.

The problem it's that I will always have to use db, and there is a lot of fallas database and it' will open deppends of an event.

Is there any way to not have to close db to open other database ? to use both

regards

@Julian You are adding connections with same name:

QSqlDatabase::addDatabase("QSQLITE");

This uses default connection name, see http://doc.qt.io/qt-5/qsqldatabase.html#addDatabase
Just specify connection names as

db= QSqlDatabase::addDatabase("QSQLITE", "first_connection");
fallas= QSqlDatabase::addDatabase("QSQLITE", "second_connection");

@vouchermedia I already explained how it should be done above.
So, what exactly is the problem?
Is your question related to Qt (you're talking about a website)?
"If i want to open one db when another data base is open is not possible" - this is not a problem description at all. What exactly does not work? Any errors/warnings? How do you open both databases? Can you show your code?

@jsulm That was spam message.
