[SOLVED] Two database connections with different drivers at the same time?

  • Hello!

    I try to establish two database connections, one with PostgreSQL and second with SQLite. I start with code:

    @QSqlDatabase mainDatabase = QSqlDatabase::addDatabase("QPSQL", "MainDatabase");
    QSqlDatabase mapDatabase = QSqlDatabase::addDatabase("QSQLITE", "MapDatabase");@

    then I setup and test connection with PostgreSQL - everything its fine so far. When I try to open SQLite databse with code:

    if (!this->mapTilesDatabase.open())
    // error handling

    I recieve error: Driver not loaded.

    Is it possible to use two different database divers simultaneously at all?

  • Welcome to DevNet!

    Using different database drivers works without problems. Is the sqlite driver really available? What the output of

    qDebug() << QSqlDatabase::drivers();

    I'm not sure if that's of importance, but in your second snippet you set the database name on mapDatabase but try to open mapTilesDatabase.

  • @Volker thank you for response. Reason of this problem was not Qt-related. I somehow removed qsqlite plugin from my system. After reinstalling Qt everything works fine.
