Re: [Cppcms-users] Cppdb: How to fetch a column of unknown type at compile time?

Hi,
reading this example

 try {
>        int x = r.get<int>(v);
>      }
>      catch(cppdb::bad_value_cast const &e) {
>        // ok it can't be integer
>      }

I'm thinking : could it be possible to provide a way to make it return a
specific value instead of throwing when the conversion can't be done?
I'm not sure that would be useful in this case but it have been when using
boost::property_tree for example.
Something like

 int x = r.get<int>( v ,  -1 ); // return -1 if something gone wrong

Alllowing the two syntaxes help avoiding unnecessary try/catch when you just
want an obviously wrong result instead of a potential exception you'll have
to remember to catch to stop crashing.
