Body
this question is very shallow, but i will try to provide some ressources as this shows up pretty on top on many searches. First of all, you will have to compile the MYSQL driver for the QtCreator for your operating system. For Windows, check <a href="https://stackoverflow.com/questions/1530282/qt-mysql-connectivity-using-windows-xp-qt-creator-4-5-2windows-32-bit">QT MySql connectivity using Windows XP, Qt Creator 4.5.2(windows 32 bit)</a> Instructions for MacOS (and probably Linux) can be found here <a href="http://www.qtcentre.org/threads/45296-QSqlDatabase-QMYSQL-driver-not-loaded" rel="nofollow noreferrer">http://www.qtcentre.org/threads/45296-QSqlDatabase-QMYSQL-driver-not-loaded</a> Once your qt install includes the mysql driver, you can use the database with the (QSqlDatabase)(developer.qt.nokia.com/doc/qsqldatabase.html) class. Copying from <a href="http://cartan.cas.suffolk.edu/oopdocbook/html/qmysqldatabase.html" rel="nofollow noreferrer">here</a>: <pre><code>QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL"); db.setHostName("localhost"); db.setDatabaseName("mysql"); db.setUserName("root"); db.setPassword("rootPW"); if (!db.open()) qDebug() << "Failed to connect to root mysql admin"; </code></pre> After that, you can use QSqlQuery to work with the database handle, e.g. <pre><code>QSqlQuery query("SELECT * FROM mysql",db); </code></pre> and print the results like <pre><code>while (query.next()) { qDebug() << "first column:" << query.value(0).toString(); } </code></pre> Code is not tested, but the Qt Documentation should clarify all details

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
