MySQL UPDATE QUERY

hello I need help with an update query in MYSQL

I have 2 tables
c_item_property   (TABLE NAME)                             c_document  (TABLE Name
     c_id   int                                        1 to 1                      c_id    int
     ref   int                                          1 to 1                      id    int
     visibility    tinyint(4)                                                     path    varchar

ok... so between the 2 tables I need to update the c_item_property table
with the 1 to 1 relationship (i think it might be a join.. not sure) between c_id .....and the ref to id  1 to 1 relationship.

I need to update visibility to  1      when path =  '/week_03'

thanks for your help

this article will explain how you need to write your UPDATE , though you must check out which syntax you need to pick for MySQL:

or directly the mysql reference for UPDATE:

in code, it might be something like this  
UPDATE c_item_property   ip, c_document  c
  SET ip.visibility = 1
WHERE ip.id = c.id
  AND c.path =  '/week_03'
