Transpose rows to columns

Hi,

I have a query that returns data like this:

cust_id        cust_name    month        cost    revenue        margin
991234        ABC        2003-07-01    10    15        5
991234        ABC        2003-08-01    11    17        6
991234        ABC        2003-09-01    12    19        7
991235        XYZ        2003-07-01    13    21        8
991235        XYZ        2003-08-01    12    19        7
991235        XYZ        2003-09-01    11    17        6

I want to turn it around so it displays like this:

991234,ABC,2003-07-01,10,15,5,2003-08-01,11,17,6,2003-09-01,12,19,7
991235,XYZ,2003-07-01,13,21,8,2003-08-01,12,19,7,2003-09-01,11,17,6

(I've used commas to shorten the layout for the example)

Does anyone have some ideas on how to do this?

Thanks,
