mehrere columns bei subselect

[King^Lully]

  
SELECT  
 a.id,  
 (  
 SELECT  
  width  
 FROM  
  photos  
 WHERE  
  (user_id = a.id)  
 ),  
 (  
 SELECT  
  height  
 FROM  
  photos  
 WHERE  
  (user_id = a.id)  
 ),  
 a.name  
FROM  
 table a  

ERROR 1241 (21000): Operand should contain 1 column(s)

Weiss jemand wie man width und height in das Main-Select übernehmen kann?

Oder:

  
SELECT  
 a.id,  
 width,  
 height,  
 a.name  
FROM  
 table a,  
 user  
WHERE  
 (a.id = user.user_id)
