UPDATE Multiple Records At Once?

From

I'm trying to update a customer record in a table however I need to
change several values (cust_address, cust_contact, cust_email). My
question is how do I properly format this into one single command?


forza=# SELECT cust_id, cust_name, cust_address, cust_contact, cust_email
forza-# FROM customers
forza-# WHERE cust_name = 'iamUNIX'
forza-# ; cust_id   | cust_name |     cust_address      |  cust_contact  |
cust_email
------------+-----------+-----------------------+----------------+--------------------1000000006 | MobileNX   | 200
SouthShore Drive | Carlos Mennens |
 
carlos@mobilenx.com
(1 row)

I did a quick Google search and I can see there is a method or
procedure which involves parenthesis () however I'm not sure how I
would change all the values listed above under one command. Can anyone
please give me a quick example so I can see how this is drawn out via
ANSI SQL?

UPDATE customers   SET cust_address = 'foo',       cust_contact = 'Arthur',       cust_email = 'arthur@foo.bar'
WHERE cust_name = 'iamUNIX'
