    By default only the Sqlite drivers are compiled.

    Check your {QT_DIR}\plugins\sqldrivers folder.

    If its not there just go to {QTDIR}\src\plugins\sqldrivers\mysql and do the usual qmake, nmake , nmake install.

    You will need to copy the .dll to your application’s directory or in a place that windows looks for dlls.
