[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<int, double, std::string> 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<X,TUPLE>::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?
