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
