old guide is old, apparently (2008).
it lists 24 fields for the table, and there are only 22 (and in a different order)
use describe <tablename>; to get an overview of the table you are working with in mysql
output:
mysql> describe object;

| ypos | float | NO | | 0 | |

22 rows in set (1.33 sec)then you'll need to make corrections to you query to match the order in the current database and add/remove fields that are incorrect in the guide.
this line is quite obviously misleading:
Basic SQL knowledge (Not necessary but useful)might be handy to update the guide after you get it working. :)
