sql - MySQL, DELETE Query with a Join

Question

Can someone help me understand what's wrong with this query:

DELETE FROM noteproject 
INNER JOIN note ON noteproject.noteID = note.noteID
INNER JOIN person ON note.personID = person.personID
WHERE noteID = '#attributes.noteID#' 
  AND personID = '#attributes.personID#'

I have no db at the moment to test what I'm saying, but here's a reference to the mysql docs where your case is taken as an example:

You can specify multiple tables in a DELETE statement to delete rows from one or more tables depending on the particular condition in the WHERE clause.

And also:

1) For the first multiple-table syntax, only matching rows from the tables listed before the FROM clause are deleted.
2)For the second multiple-table syntax, only matching rows from the tables listed in the FROM clause (before the USING clause) are deleted.
The effect is that you can delete rows from many tables at the same time and have additional tables that are used only for searching:

1)
DELETE t1, t2 
FROM t1 INNER JOIN t2 INNER JOIN t3
WHERE t1.id=t2.id AND t2.id=t3.id;

2)
DELETE FROM t1, t2 
USING t1 INNER JOIN t2 INNER JOIN t3
WHERE t1.id=t2.id AND t2.id=t3.id;

These statements use all three tables when searching for rows to delete, but delete matching rows only from tables t1 and t2.
