Update table from another table and different database

mysql, sql

Solution

UPDATE 
  prc.user, 
  prc_test.user 
SET 
  prc_test.user.pwd_user = prc.user.pwd_user
WHERE 
  prc_test.user.name_user = prc.user.name_user

Problem

Basically, what I want to do is the following : I have a table 'users' in my first database (prc), like this : ``` prc.user : id_user : 45 | name_user : Test | login_user : test | pwd_user : test [...] ``` And in my second database (named : prc_test) ``` prc_test.user id_user : 45 | name_user : Test | login_user : test | pwd_user : test [...] ``` The thing I want to do, is update all the "pwd_user" fields in "prc_test.user" with the values from pwd_user from "prc.user" But in the prc_test.user, the id are not the same as in prc.user, so I thought of doing it with the "name_user", (there are no doubles). Any clue in how I can do it ? I searched on Google, but what I found is always for some specific cases, or for insert statements... (I'm using MySQL5.5) Thanks !
