Are you quite sure there can never be more than 16 orders per ID ?
The form your table is in now is actually the preferred form. It's called an
associative table, and logic suggests that it sits between a table that
holds more info on the IDs, and a table that holds more info on the orders.

I have no idea how you got here but there is no reason to do it that
way. This will work just fine and I do it every day in php.
However I don't use mysqli I still use ...
mysql_connect
mysql_select_db
mysql_real_escape_string
mysql_query
Don't forget to use the mysql_real_escape_string

tuning your query cache.
Start off with something like 32M and incrementally tune it.
You can monitor some query cache related server variables.

Hello,
I hope that this is the right list.
I have a database that has been running for years in latin1 but a
software update changed it in to utf8 that would be no big deal if we
know it right away so we could change the database.
The big problem is that the database has been running for 2
