\title Changes to Qt SQL
\ingroup changes-qt-5-to-6
\brief Migrate Qt SQL to Qt 6.
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
