The current MySQL dissector ignored the parameters as metadata is needed from
previous packets to decode the fields. I added the necessary code to store
these in conn_data and developed dissector for all fields I could reproduce on
the network.

As MySQL doesn't have a clear, thorough documentation about this part (for
example, which types are allowed in these packets) I created as many different
captures as I could, using Python (oursql), PHP (mysqli), Java (Connector/J)
and C (libmysql). These are all attached in a ZIP file, along with my proposed
patch.
