    Unfortunately, we won't be able to solve the problem for you :). Try to perform a research on some folders, you might be lucky and find your base. On windows, you could maybe try looking at %AppData% folder.

        @db.setDatabaseName(":memory:");@
        If you gave database name like above, db file would reside in the memory.

        @db.setDatabaseName("your_db_name");@
        But , in this case,db will be created in the same folder where the executable is residing.

          Assuming, you are using QtCreator with "default" build settings (projectname_build_simulator), Db file can be found here,if you have given like
          @db.setDatabaseName("your_db_name");@

            I guess you dont need to worry about this. There is no typical extension, other than the file name, unless you give one.

                  Thanks for the reply Rahul. You've been a great help.

                  EDIT: I tried using setDatabaseName() as you suggested though I just receive an error.

                  Result of expression 'db.setDatabaseName' [undefined] is not a function.

                  Using the "SQL Local Storage example":http://doc.qt.nokia.com/4.7-snapshot/declarative-sqllocalstorage.html as reference, where should I call the function?

                    I am not really familiar with QML though, i suppose , you can still follow how we connect in a normal Qt application. :) ie,for example, in your main,
                    @int main(int argc, char *argv[])
                    {
                    QApplication app(argc, argv);
                    QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE");
                    db.setDatabaseName("db_name");@

                    Am sorry, :( dont know much about QtQuick :(

                    And don't forget to add sql module in *.pro file.

                      So the reason why I can't find the database is its filename is composed of a combination of hexadecimal numbers. I finally found it at last. Thank you very much for the help guys. I guess this is completely solved.
