    Maintenance Tool does not work, I get the next message: at least one valid and enabled repository required for this action to succeed
    In the Maintenance Tool, start by selecting "Update components". Then click on the Settings button.
    Then a Settings window will open and in there, then click the Repositories tab, click on User defined repositories, click on the Add button and type http://download.qt-project.org/online/qtsdkrepository/windows_x86/desktop/tools_maintenance.
    I tried many website but still I get the same message.

      So you used the offline installer ?

      Anyway, there's not that many website: http://download.qt.io/official_releases/qt/ the single folder under the version folders contain the sources. Since you're on Windows get the .zip file.

          I downloaded qt-everywhere-src-5.12.1 and from what I got from https://www.seppemagiels.com/blog/create-mysql-driver-qt5-windows#mysql_path_note, I renamed the folder to Sources instead of the long qt-everywhere-src-5.12.1.
          I also placed it in the Qt folder was installed in. (C:\Qt\ Qt5.12.1)
          Open cmd.exe, and enter the following commands:
          c:\Qt\Qt5.12.1\5.12.1\mingw73_64\plugins\sqldrivers>C:/Qt/Qt5.12.1/5.12.1/mingw73_64/bin/qmake -- MYSQL_INCDIR=C:/MySQL/include "MYSQL_LIBDIR=C:/Program Files/MYSQL/MySQL Server 8.0/lib/libmysql.lib" mysql.pro
          and again ... I'm disappointed

            That line doesn't make sense, why are you trying to execute qmake inside the sqldrivers folder from your already installed Qt ? And why are you passing once the path without space for the includes and then the one with spaces for the libraries ?

              What is the right line ?
              I have read the post from https://forum.qt.io/topic/92626/cant-connect-to-mysql-database-qmysql-driver-not-loaded/15 line by line but it doesn't fit.
              Please, light me!

                I will start again.
                On website https://doc.qt.io/qt-5/sql-driver.html#how-to-build-the-qmysql-plugin-on-windows
                first line is: cd %QTDIR%\qtbase\src\plugins\sqldrivers wich for me is:
                c:\Qt\Qt5.12.1\5.12.1\mingw73_64\plugins\sqldrivers>

                Now I'll go back to website
                second line:
                qmake -- MYSQL_INCDIR=C:\MySQL\include "MYSQL_LIBDIR=C:\MYSQL\MySQL Server <version>\lib\opt"

                MYSQL_INCDIR is include folder from MySql folder
                MYSQL_LIBDIR is lib folder from MySql folder

                For me the second line it should be something like this

                c:\Qt\Qt5.12.1\5.12.1\mingw73_64\plugins\sqldrivers>qmake -- MYSQL_INCDIR=C:\Program Files\MySQL\MySQL Server 8.0\include "MYSQL_LIBDIR=C:\Program Files\MySQL\MySQL Server 8.0\include"
                When I run this line I get an error: 'qmake' is not recognized as an internal or external command,
                operable program or batch file.

                Also I don't find the opt folder

                  @Stelian You need to call qmake from the source code directory of Qt source code you downloaded, not from your installed Qt.
                  This is your Qt installation: c:\Qt\Qt5.12.1\5.12.1\mingw73_64\plugins\sqldrivers
                  Look again at the link you posted: c:\Qt\5.10.1\Src\qtbase\src\plugins\sqldrivers is used there (in your case version would be 5.12.1).

                  "'qmake' is not recognized as an internal or external command, operable program or batch file." - use absolute path to qmake.

                    @jsulm Thank you for your reply.
                    I have modified the line with this one.c:\Qt\Qt5.12.1\Sources\qtbase\src\plugins\sqldrivers>qmake -- MYSQL_INCDIR=C:\Program Files\MySQL\MySQL Server 8.0\include "MYSQL_LIBDIR=C:\Program Files\MySQL\MySQL Server 8.0\lib" but I get the same error: "qmake' is not recognized as an internal or external command, operable program or batch file"

                      Use the full path to the qmake executable or start a Qt enabled command line.

                          @Stelian This error is unrelated to Qt: you have a path with spaces (good example for why you should avoid such paths!). You need to put such paths into "":

                          c:\Qt\Qt5.12.1\Sources\qtbase\src\plugins\sqldrivers>C:\Qt\Qt5.12.1\5.12.1\mingw73_64\bin\qmake -- MYSQL_INCDIR="C:/Program Files/MySQL/MySQL Server 8.0/include" MYSQL_LIBDIR="C:Program Files/MYSQL/MySQL Server 8.0/lib"
                          

                          "I have no patience" - well, one should have when developing software...

                            maybe it's a typo and it's supposed to be patients, meaning als patients are gone and there's now more time on hand for developing software

                              And I,ve run mingw32-make

                              'mingw32-make' is not recognized as an internal or external command,
                              operable program or batch file.

                              Do I have to add the path to make.exe in environment variables ?
                              But I don't find de make.exe file.
                              What else do I have to do ?

                                I,ve run c:\Qt\Qt5.12.1\Sources\qtbase\src\plugins\sqldrivers>C:\Qt\Qt5.12.1\5.12.1\mingw73_64\bin\qmake -- MYSQL_INCDIR="C:/Program Files/MySQL/MySQL Server 8.0/include" MYSQL_LIBDIR="C:Program Files/MYSQL/MySQL Server 8.0/lib"
                                and I get the next message:

                                Qt is now configured for building. Just run 'mingw32-make'.
                                Once everything is built, you must run 'mingw32-make install'.
                                Qt will be installed into 'C:\Qt\Qt5.12.1\5.12.1\mingw73_64'.
                                

                                And I,ve run mingw32-make

                                  I,ve looked foe mingw-make.exe file into C:\Qt\Qt5.12.1\5.12.1\mingw73_64\bin
                                  I don't find it.
                                  Do I have to follow next steps ?

                                  uninstall your current MinGW installation
                                  reinstall MinGW and select the following option in the setup dialog
                                  a) Custom
                                  b) Compilers C & C++
                                  c) MSYS
                                  extend your PATH environment variable in the System Properties / Environment Variables dialog of windows by adding C:\MinGW\msys\1.0\bin;C:\MinGW\bin; in front of the values that are already there
                                  restart machine

                                              QCoreApplication a(argc, argv);
                                          
                                              QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL");
                                              db.setHostName("localhost");
                                              db.setUserName("root");
                                              db.setPassword("DSa81&l12&z26");
                                              db.setDatabaseName("Employee_management");
                                          
                                              if (db.open())
                                              {
                                                  qDebug() << "Database connected successfuly!";
                                              }
                                              else
                                              {
                                                  qDebug() << "Database is not connected!";
                                              }
                                          
                                              return a.exec();
                                          }
                                          

                                          I receive the message "Database is not connected!", which means there are still some blurring about the QMYSQL driver.
