Hello
If the forum I saw many problems using QSqlTableModel in queries, using setFilter () sql limiting, a comparison of the method QsqlQueryModel setQuery () solve this problem, but not well integrated QSqlQueryModel to sort data in QTableView sortingEnabled to order the sql query (producModel-> QSqlQueryModel :: setQuery (QString ("Select * From product where (product.id =% 1) limit 200"). arg (id)) ;) vanishes, well this is just some , what would be the best option
