[Cppcms-users] Cppdb: How to fetch a column of unknown type at compile time?

How to fetch a column of unknown type at compile time with cppdb?

For example in soci we can do code like this:

        row r;
        sql << "select arbitrary_column from arbitrary_table where id =
        1", into(r);
        
        const column_properties & props = r.get_properties(0);
        
        switch(props.get_data_type())
        {
        case dt_string:
            cout << r.get<std::string>(i);
            break;
        case dt_integer:
            cout << r.get<int>(i);
            break;

    	//others cases...
        
        }

What is the recommended way to accomplish this with cppdb? ( If one
exists).


Thanks.
