QSqlRelationalTableModel settable unable to find

[nietzsche]

This is my code.

bankModel = new QSqlRelationalTableModel(this,_db);
bankModel->setTable("HR_BANK_SUC");

bankModel->setEditStrategy(QSqlTableModel::OnManualSubmit);
bankModel->setRelation(1, QSqlRelation("HR_BANKS", "HR_BANK_ID", "HR_BANK_NAME"));
bankModel->setRelation(2, QSqlRelation("FND_STATUS", "FND_STATUS_ID", "FND_STAT_NAME"));
bankModel->select();

But when i run my app, this make an error... "unable to find table HR_BANK_SUC".. the table exists and de database is open, the error is just with QSqlRelationalTableModel.. any suggest??? thanks
