[Cppcms-users] small patch for cppdb error reporting

[<ele...@ex...>]

After applying this patch the annoyance factor has dropped drastically for
me. For anyone who wants to use it it's here.

For Artyom:

On FreeBSD (at least) iODBC is the default. For example Virtuoso database
which is required by KDE4 only builds against iODBC (as far as I can tell
from FBSD ports)

Maybe the situation is similar in Linux, I dont know.
