QTableView & QSqlQueryModel :when query changes

[soleverlee]

there is a QTableView to display query results, and I set it's model as a QSqlQueryModel:
@
QSqlQueryModel* sqlModel = new QSqlQueryModel();
sqlModel->setQuery(“SELECT id,title FROM tbarticle where key = '1'”, db);
tableView->setModel(sqlModel) ...
@
Now I'd like to query key = '2',and show them on the same tableView, what should I do?
Should I reset the model of the tableview,or change it?

Another question, if I insert into the database, how should I update the view?
Looking forward to your ideas!

to your first question: call setQuery() with the new query.
