.exec() is nice, but I think that Alexander has a point with operator()
being idiomatic in the C++ world :-)

sqlpp11 is using .front() and .pop() if you want to go through a result
set step by step. Otherwise there is the wonderful for-loop, of course:

for (const auto& row : result) {...}

C++ developers should feel right at home with that, I guess.
