Subject:RE: MySQL++ issue with exceptions
View as plain text  
If you compile with the "--with-exception" flag turned on, all exceptions generated will
derive from std::exception and you can use the what() method to find out what exception
is thrown.

BTW, make sure you use "--with-exception" not "--with-exceptions"; don't ask me how I
know.
