                  Get access of all sql modules using QT += sql in .pro file of your project.

                  You can create a database object to create a connection with your database using QsqlDatabase Class

                  http://doc.qt.io/qt-5/sql-connecting.html

                  With a created database object, you can use QSqlQuery to insert, update, remove or recover information of your database

                  http://doc.qt.io/qt-5/sql-sqlstatements.html

                      Hi
                      Can you try this demo project.
                      It runs for me and if yours still fail, something is wrong with your Qt install.
                      https://www.dropbox.com/s/uo43f7sbiwcjazv/mySqlite.zip?dl=0

                      output:

                      create table: true

                      "Young"
                      "Holand"
                      "Gordon"
                      "Robitaille"
                      "Papadopoulos"

                        Hi, here's my source code:

                        QSqlDatabase m_database = QSqlDatabase::addDatabase("QMYSQL");
                        m_database.setDatabaseName("127.0.0.1");
                         m_database.setPort(3306);
                        m_database.setUserName("root");
                        foreach(QString pilote, m_database.drivers())
                            qDebug()<< "Pilote: " << pilote;
                        if(m_database.open())
                            qDebug() << "Connexion réussie.";
                        

                        and here's the result:
                        QSqlDatabase: QMYSQL driver not loaded

                        QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7

                        Pilote: "QSQLITE"

                        Pilote: "QMYSQL"

                        Pilote: "QMYSQL3"

                        Pilote: "QODBC"

                        Pilote: "QODBC3"

                        Pilote: "QPSQL"

                        Pilote: "QPSQL7"

                          I guess you are hitting the usual problem: do you have the MySQL client libraries that are accessible by your application ?

                            I don't know what a MySQL client library is and how to get it and what its importance?
                            if it is necessary to make simple I know nothing in module QtSQL
                            so if you can really help me use the QtSQL module, if there are things to download, you can tell me by posting the download link.

                              The MySQL issue already triggered numerous threads on this forum, you should search for them.
