Hello guys!

I can not get the output 201101 with this query in MySql:

Code:
mysql> SELECT MAKEDATE(YEAR(CURDATE())-1,1) input 
      ,CONCAT(YEAR(MAKEDATE(YEAR(CURDATE())-1,1)),MONTH(MAKEDATE(YEAR(CURDATE())-1,1))) output;
 
+------------+--------+
| input      | output |
+------------+--------+
| 2011-01-01 | 20111  |
+------------+--------+
1 row in set
I hope your help.
Saludos!
