How to remove a record from a table with a composed primary key using QModelIndex ?

Hello,

How to remove a record from a table with a composed primary key using QModelIndex and removeRow?

In tables with simple primary key (just one column) it works fine with:

Code:

---

QModelIndex index = sequenceTableView->currentIndex();
    if (!index.isValid())
        return;
    sequenceModel->removeRow(index.row());
    }

---

but with 2 columns (with similar code) i can't delete the record and in the output window appears the message:

QSqlQuery::value: not positioned on a valid record


Any help would be appreciated.
Thanks,
Palma

the problem is solved, the index was returning wrong types. I was pretending to remove a row from a QSqlRelationalTableModel whose index is formed by two fields that are foreign keys, and the index was returning the names instead of the ids....

Can you please provide some input on how you solved this problem?

Thanks,
