On second thought it looks like that (companies as c LEFT JOIN companies)
actually is the second FROM item. Adding parenthesis to the explicit
cross join version gives the same error:
SELECT p.lname, p.fname, p.job_title, p.company_nbr, p.email, c.company_name
FROM people as p
CROSS JOIN (
companies as c
LEFT JOIN companies ON c.company_nbr = p.company_nbr
);
So the comma in the FROM item list has lower precedence than the join
operators.
