Re: [Boost-users] Need ideas...

I am trying to generalize the concept of putting database data into boost::tuple objects. I'm thinking syntax similar to something like so:

typedef boost::tuple row;

row r = SqlQuery<row>::run_query(db, "select * from x");

I imagine something like so being contained in the processing:

TUPLE t; ... t.get<X>() = boost::lexical_cast< typename boost::tuples::element::type >(data[X]); // data is char **

Where X is the index of the element and the entire tuple is iterated in this manner. I thought maybe there would be something in MPL that could help but I'm not seeing it.

Anyone got any bright ideas?
