Custom SQL in QSqlTableModel/QTableView

Good day, lords of the QT's!

I'm using QSqlTableModel and QTableView, I wonder: this is the best way whether custom the SQL, making select between two or more tables? Can use submitAll? I think not, what can I do?

Thanks,

Use QSqlQueryModel or QSqlRelationalTableModel if the main table contains foreign keys to other tables and you simply want to subsitute them with a column from a related table.

Note that QSqlQueryModel is a read-only model.

Sure, QSqlQueryModel can not use because I will need to change the information. I still I have a QSpinBox (not delegate), which put the value in a certain field. Any suggestions?

Have a look at QDataWidgetMapper.
