Hi,
I've got problem with one specific query. I've got the table
with many of rekords like these:
 
name     |  quantity    | date
-------------------------------------------------------
aaa            2                2003-04-01
bbb            4                2003-04-12
ccc            5                2003-05-12
aaa            3                2003-01-14
aaa            1                2003-12-09
bbb            9                2003-08-08
 
and so on ...
 
Does anybody know how make query which return grouped
records by month of year and name (also sum of quantity).
It is possible to make a query whitch return something like that:
 
name | 01 | 02 | 03 | 04 | ... | 12 (months)
------------------------------------------------
aaa     x     x     x    x    ...   x
bbb     x     x     x    x    ...   x
ccc     x     x     x    x    ...   x
 
where x means sum of quantity in month.
It is possible to make it in one query?
I know that in Access is construction : PIVOT.
 
Thanks
Adam
