[Cppcms-users] Trying cppdb connection & catch exceptions

[augustin <aug...@ov...>]

Hello Artyom and all,

I wish to test my DB connection (e.g. to check that the connection string is 
working), and catch any exception arising.

Here is the code:


        // Testing that the connection string actually allows us to connect to 
the DB.
        try {
                cppdb::session sql(connection_string);
        }
        //catch (std::exception const &e) {
        catch (cppdb::cppdb_error const& e) {
                _bInit_db = false;
                return;
        }

However, when the connection string is wrong, the application crashes 
altogether:

cppdb::mysql::Access denied for user 'WRONG'@'localhost' (using password: YES)

How to test the DB connection and gracefully handle failed DB connections?

Thanks,

Augustin.
