    @Babs Ok. So now you can test db.open() - it returns a value. On false, error should be present in lastError().

    @artwaw it returns false and the error driver not loaded. I do the verification:

            if(!db.isOpen()){
                db.open();
                qDebug()<<db.lastError().text();
            }

      @Babs Are you completely sure that addDatabase() has been called at any point before call do QSqlDatabase::database()?
      You could also test if driver is available by using QSqlDatabase::drivers() and other methods described in documentation.

      For more information please re-read.

      Kind Regards,

              @artwaw i'm working with QBS. When i don't specify the connectionName in addDataBase() function it open. I have the error "number of parameters incorrect". I think i don't have the good parameter types. I defined a QString as a TEXT is SQLite. Is it correct?

                  @Babs ups. I have literally zero experience with qbs...
                  I am afraid you'll have to wait for someone who knows something about it, I am sorry.

                  For more information please re-read.
