What is the correct syntax to include the result of this select query as part of an update. In other words i want an update query that uses this select query as a sub query.

SELECT `subscriberID`, `email`, 

CONCAT( 
SUBSTR(  `email` , 1, INSTR(  `email` ,  '@' ) -1 ) , 
SUBSTR(  `email` , 
	INSTR(  '@',  `email` ) +1, 
	INSTR(  '.',  `email` ) -1 - 
	INSTR(  '@',  `email` ) ) , 
	subscriberID ) AS uname

FROM newsletterSubscriber
