for results , we access it using iterators usually.
But in case we will get one result apparently, we hope to directly access data.
is it possible?

Have you profiled the code? If not, how do you know that such an

In virtually all situations, the speed bottleneck is either I/O
(network, disk...) or the database itself. Unless you have a very
unusual situation, speeding up MySQL++ should only help significanly if
there is a massive inefficiency in the library somewhere. The only such
inefficiency I'm aware of is that it copies data too many times, but
that only matters for large result sets, not small ones like what you're
talking about.

sorry ,I think it's mistake about profile.

I hope not more simple code , but more efficient.

about a single result, I think it is not necessary write a whole loop.
