I've just released a new site which has nodes only accessible by
authenticated users.  These nodes also have attached files via
upload.module.  I struck a problem where users were unable to download
these files due to a bug in upload.module, instead they received 'page
not found', with the following error output:

"user error: Unknown table 'na' in where clause
query: SELECT DISTINCT(f.nid), f.* from cms_files f WHERE
(na.grant_view = 1 AND CONCAT(na.realm, na.gid) IN
('all0','term_access2','term_access6')) AND filepath =
'files/20050307_minutes.doc' in
/srv/www/htdocs/docs_renegades/www/includes/database.mysql.inc on line

The problem was that the node_db_rewrite_sql() WHERE statement was
being inserted, but not the corresponding JOIN statement (where 'na' is
declared as an alias of {node_access}).

Looking through the code it seems this is because the regex in the
db_rewrite_sql() function is looking for 'FROM' (all caps), whereas the
upload.module query sent to db_rewrite_sql has 'from' (lower case). 
Changing from -> FROM fixes the problem.

This patch should apply to 4.6.0 and cvs, though I didn't look to see
if the cvs version of db_rewrite_sql() still looks for an uppercase
