I've got a Table called AdslAccount and in this table theres a few columns

userName, downloadMb, date (and a few more but they aren't relevant)
It looks like this

```
user1, 20, 10-10-2013  
user2, 12, 10-10-2013  
user2, 12, 09-10-2013  
user1, 13, 09-10-2013  
user2, 12, 09-09-2013  
user1, 13, 09-09-2013 

```

Now what I want with a Query is a list of all users with their total downloadMb per MONTH (taking in account that there are more 09's and 10's in different years)

I've tried many MANY queries but none did what I want.  

Could someone guide me in the right direction or perhaps provide me with a correct query? 

Thanks in advance!
