From 8ba9d2e0220777bc1a2322eeece7fa9a5c55a96d Mon Sep 17 00:00:00 2001 From: Andy Shaw Date: Thu, 11 Jun 2020 10:49:50 +0200 Subject: Change boundValues() to return a QVariantList This enables the order of boundValues to be consistent as with a QMap it could have been reordered which can be a problem for positional bindings. [ChangeLog][QtSQL] Changed signature of QSqlQuery::boundValues() to return a QVariantList Fixes: QTBUG-51609 Change-Id: I1c80fa8522fa7352723420b6fc9ec466406315fb Reviewed-by: Volker Hilsheimer --- src/sql/doc/src/qt6-changes.qdoc | 66 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 66 insertions(+) create mode 100644 src/sql/doc/src/qt6-changes.qdoc (limited to 'src/sql/doc/src') diff --git a/src/sql/doc/src/qt6-changes.qdoc b/src/sql/doc/src/qt6-changes.qdoc new file mode 100644 index 0000000000..4bde13e0ed --- /dev/null +++ b/src/sql/doc/src/qt6-changes.qdoc @@ -0,0 +1,66 @@ +/**************************************************************************** +** +** Copyright (C) 2020 The Qt Company Ltd. +** Contact: https://www.qt.io/licensing/ +** +** This file is part of the documentation of the Qt Toolkit. +** +** $QT_BEGIN_LICENSE:FDL$ +** Commercial License Usage +** Licensees holding valid commercial Qt licenses may use this file in +** accordance with the commercial license agreement provided with the +** Software or, alternatively, in accordance with the terms contained in +** a written agreement between you and The Qt Company.
