Error in User Manual?

#1

Hi!

I'm pretty new to MySql++ so please forgive me if I've overlooked
something. Here's my problem.

In Section 2.3, "Queries That Return Data: Dynamic Method" of the User
Manual (as on
http://tangentsoft.net/mysql++/doc/u.../overview.html) the
following is stated:

Quote:

The easiest way to retrieve data from MySQL uses a Result object,
which includes one or more Row objects. Because these classes are
std::vector-like containers, you can treat the result set as a
two-dimensional array. For example, you can get the 5th item on the
2nd row by simply saying result[1][4]. You can also access row
elements by field name, like this: result[2].lookup_by_name("price").

But as far as I can tell the Result object doesn't even supply an
operator[] and if I try to use the "result[][]" notation I get a compile
error ("error: no match for 'operator[]' in 'result[0]').

So, what's the right way? Should I do "result.at(0)[0]" instead?

I'm using MySql++ 2.0.5.

Thanks.

-Kim

Yes, that's the new syntax.

I'll fix the error in the next version.

This returns a "ambiguous overload for 'operator[]' in
'mysqlpp::Result::at(unsigned int) const(0u)[0]" error for me.
Though "result.at(0).at(0)" made it work.

I'm using mysql++-2.0.5.
