      Try not passing -p switch. I guess you will be prompted to type in your password.
      or
      @/opt/lampp/bin/mysql -u root testTwo@

          I'm sorry i just confused you with my last post.

          @/opt/lampp/bin/mysql -u root -p 123456 testTwo@

          I thought that mysql would prompt you but it didn't.

            Do it this way, then it will prompt for a password:

            @/opt/lampp/bin/mysql -D testTwo -h localhost -u root -p
            @

                Cut it into pieces or use something like pastebin.

                        Hm, apparently mysql is rather strict in terms of specifying parameters. Try to follow ¤ Dii ¤'s instructions.

                            Here is his post.

                            [quote author="¤ Dii ¤" date="1286874970"]Do it this way, then it will prompt for a password:

                            @/opt/lampp/bin/mysql -D testTwo -h localhost -u root -p
                            @

                                BTW if you do this, AND it's working, you end up in mysql command line interface, you can get out with 'exit'

                                    Wow, mysql is full of surprises. Never got those with psql. ¤ Dii ¤, does it have \q command?

                                          lyuts: yes \q is working too

                                          doforumda: ok, so get into the mysql comand line with the command above

                                          /opt/lampp/bin/mysql -D testTwo -h localhost -u root -p

                                          and then do this:

                                          grant all on testTwo.* to 'root'@'localhost' ;

                                          Then we have a working mysql, and the rights are granted, we can get back to your Qt program.
