      Try this codesnippet:

      @

      void YourClass::init()
      {
      //...
      initDB("../../../db/mydb.db3"); // of course your db path goes here
      //...
      }

      void YourClass::initDB(QString dbPath)
      {
      vc2DB = QSqlDatabase::addDatabase("QSQLITE");
      vc2DB.setDatabaseName(dbPath);
      vc2DB.open();
      QSqlQuery query;
      query.exec("PRAGMA foreign_keys = ON;");
      bool b = query.exec("select id from role where code = 'SU'");
      if (!b) {
      std::cerr << "Failed to open database: " << dbPath.toAscii().data() << std::endl;
      exit(-1);
      }
      }
      @

              What? I don't understand this.

              But! If the open() function can't open your database, it will open with the given name an another database in QSQLITE! See your databaseS.

                  even though the file does not exist, the SQLite will try to create it.

                    Anyway, can you run (from your code) a simple SELECT on your database? Have you got a resultset?
                    Have you grant at all for your tables?
