Does 'QSqlQueryModel' have a bug?

[nuntawat]

That is not true. You can do this (it works in my code):

QSqlQuery query;
query.prepare("SELECT * from table_name where column = ?");
query.addBindValue("value");
query.exec();
model->setQuery(query);

QSqlQuery query;
query.prepare("SELECT * from table_name where column = ?");
query.addBindValue("value");
query.exec();
model->setQuery(query);

To copy to clipboard, switch view to plain text mode 

Thanks!!! I just knew that setQuery() didn't execute the query!!
