I was wrong in saying not able to initialized a reverse_iterator with a
interator. I must confused with something else. Or maybe I got that in a
dream.
But still, in this case, there's not need to create a new reverse_iterator
variable. Things will be fine if we do this:
const result R = T.exec("SELECT * FROM " + Table + " ORDER BY num DESC");
++i;
for (result::const_iterator r = R.begin(); r != R.end(); ++r) {
--i;
if (r->at(0).as(0) != (*i)[0])
throw logic_error("Writing numbers with tablewriter went wrong: "
"expected " + to_string((*i)[0]) + ", found " + r[0].c_str());
}
T.commit();
