Mysql#errno and ActiveRecord

[julian7]

I tried to use ruby-mysql with ActiveRecord (not the new version, but it seems the last one suffers from the same problem), and I got an error about Nil class doesn't respond to zero?.

The calling code in question looks like this:

def active?
  ...
  if @connection.respond_to?(:errno)
    @connection.errno.zero?
  else
    true
  end
end

Therefore, I suggest changing Mysql#errno to this: def errno @last_error && @last_error.errno || 0 end
