Re: [Cppcms-users] Strange memory corruption during copy construction of cppdb::result

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

Ok, wrong again. i've found out whats happening.

The reason the loop was hanging is because inside the loop I was calling
result::get<string>("colname") but colname is NULL in the database.

It still seems like there is something wrong.

Accessing a null column via result::get should either throw() or return
an empty string. Not hang the application.
