Foreign key ON

[fantom]

Hello all,

I have a question concerning activating the foreign key in qt. I create a query just after opening my database (see below). Is this the correct way? How can i check it?

int main(int argc, char *argv[])
{
	QApplication a(argc, argv);
 
	QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE");
	db.setDatabaseName("d:/database/Client1");
	bool ok = db.open();	
 
	QSqlQuery query;
	query.exec("PRAGMA foreign_keys = ON;");
 
	Login w;
	w.show();
	return a.exec();
}

int main(int argc, char *argv[])
{
	QApplication a(argc, argv);

	QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE");
	db.setDatabaseName("d:/database/Client1");
	bool ok = db.open();	

	QSqlQuery query;
	query.exec("PRAGMA foreign_keys = ON;");

	Login w;
	w.show();
	return a.exec();
}
