QTableView disable selection of single column

I have a QTableView made from a MySQL query in Qt as follows:

tableView = new QTableView(this);
tableView->setModel(tableModel); 
tableView->setSelectionBehavior(QAbstractItemView::SelectItems); 
tableView->resizeColumnsToContents();

Where tableModel is a QSqlTableModel*. I found the solution here to be item->setFlags(item->flags() & ~Qt::ItemIsEditable);, but I'm not adding the data to the table item by item. So what's the solution in this case?

Inherit your own model class from the QSqlTableModel and reimplement the flags() method.

It could be like this:

class CMySqlTableModel : public QSqlTableModel
{
    public:
        CMySqlTableModel(QObject* parent)
            :    QSqlTableModel(parent)
        {}

        /**
         * Enable / disable selection for particular column.
         *
         */
        void setSelectionEnabledOnColumn(int columnIndex, bool enabled)
        {
            if (enabled)
                m_columnsNotSelectable.erase(columnIndex);
            else
                m_columnsNotSelectable.insert(columnIndex);
        }

        Qt::ItemFlags flags(const QModelIndex & index) const override
        {
             Qt::ItemFlags f = QSqlTableModel::flags(index);
             if (m_columnsNotSelectable.find(index.column()) != m_columnsNotSelectable.end())
                 f &= ~Qt::ItemIsSelectable;

             return f;
        }

    private:
        std::set<int> m_columnsNotSelectable;
}
