Dear developers and programmers,

I have a tabel with SHOP_ID, PROD_ID, ipadres and some more tables, but these are where its all about...

Looks like this:

id ip number        timestamp   shop_id prod_id

.... more
--------------------------------------------------------

Is there a way to see for each prod_id how many ip numbers there excist for each shop id?

output example

        1        2        3        4        5
---------------------------------------------
1       18       5        51       8        4
2       58       5        45       3        4
3       7        6        31       9        2

where horizontal is the prod_id and vertical is the shop_id

I've don this already:

select 

shop_id,
count(distinct(ipadres)) amount

from table

GROUP BY    shop_id

order by amount desc

but this wil give me only the result of all prod_id's combined.

I would like to have the prod_id's seperate in columns.

I hope there is a solution!

Kind Regards

これを試して 

select `prod_id`,shop_id,
    count(distinct(ipadres)) amount        
    from table        
    GROUP BY shop_id,prod_id        
    order by amount desc
