I have this:

Group, Genre
General, 80s
General, 90s
Electronic, Techno
Electronic, House

How can I display it like this:

General    80s

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Display issues (e.g. not repeating a category name) are handled in your front end code (e.g. PHP), not in the MySQL query.

This is what you are looking for.
If the columns of the table is Group and Genre then

select `group`, group_concat(genre, ',' ) 
from table
group by `group`

Open in new window

Note that the word group is a reserved word in all dbms systems so using that in a table or view could lead to parsing errors when executing sql statements.

Hi, group_concat(genre, ',' )  puts them next to eachother, how can I make them each on their own line?
Tomas Helgi JohannssonCommented:
This should do it
select `group`, group_concat(genre, '\n' ) 
from table
group by `group`

Open in new window
