    \title Changes to Qt SQL
    \ingroup changes-qt-5-to-6
    \brief The return type for boundValues() has been changed in QSqlQuery class.

    Qt 6 is a result of the conscious effort to make the framework more
    efficient and easy to use.

    We try to maintain binary and source compatibility for all the public
    APIs in each release. But some changes were inevitable in an effort to
    make Qt a better framework.

    In this topic we summarize those changes in Qt SQL, and provide guidance
    to handle them.

    \section1 The QSqlQuery class

    \section2 boundValues() Signature

    The return type for boundValues() has been changed from QMap<QString, QVariant>
    to a QVariantList. The order can be relied upon so it will be in the order of the
    binding in the prepared query. Change code like the following:

    \code
    QMap<QString, QVariant> values = boundValues();
    int id = values[":id"].value().toInt();
    \endcode

    \code
    QList<QVariant> values = boundValues().values();
    int id = values.at(0).toInt();
    \endcode

    to:

    \code
    QList<QVariant> values = boundValues().values();
    int id = values.at(0).toInt();
    \endcode
