The fix for QTBUG-101680 involves checking for the MYSQL_TYPE_JSON enum. Supporting this enum requires MySQL 5.7.9 or higher:

However, our documentation says that we support older versions:

• MySQL 5.0 for Qt 5.15 (https://doc.qt.io/qt-5/sql-driver.html )
• MySQL 5.6 for Qt 6.x (https://doc.qt.io/qt-6/sql-driver.html )
