Интерфейс к SQLite

Пример использования:

try
{
    SQLiteInterface db;
    if( !db.connect("test.db") )
    {
        cerr << "db connect error: " << db.error() << endl;
        return 1;
    }
 
    stringstream q;
    q << "SELECT * from main_history";
 
    DBResult r = db.query(q.str());
    if( !r )
    {
        cerr << "db connect error: " << db.error() << endl;
        return 1;
    }
 
    for( DBResult::iterator it=r.begin(); it!=r.end(); it++ )
    {
        cout << "ROW: ";
        DBResult::COL col(*it);
        for( DBResult::COL::iterator cit = it->begin(); cit!=it->end(); cit++ )
            cout << DBResult::as_string(cit) << "(" << DBResult::as_double(cit) << ")  |  ";
        cout << endl;
    }
 
    db.close();
}
catch(Exception& ex)
{
    cerr << "(test): " << ex << endl;
}
catch(...)
{
    cerr << "(test): catch ..." << endl;
}
