I think you want to do something like this:
select prod, group_concat(category separator ', ')
from products
group by prod;
Hope this helps.

hi all...
i have a bit of a problem with this:
table products:
----------------------
prod | category |
---------------------|
boots | winter |
boots | summer |
boots | spring |
shoes | spring |
shoes | winter |
shoes | fall |
shoes | summer |
----------------------
when i do this:
> select distinct prod as m, (select category from products where email
= m) as n from products;
i get:
ERROR 1242 (21000): Subquery returns more than 1 row
i know that the subquery returns more than one rows. i hope so...
what i'd like to see as result is:
-------------------------------------------------
m | n |
-------------------------------------------------
boots | winter, summer, spring |
shoes | spring, winter, fall , summer |
-------------------------------------------------
or at least:
---------------
m | n |
---------------
boots | 3 |
shoes | 4 |
----------------
thanks....
