MySQL Syntax

Hi,

I have this:

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

How can I display it like this:

General    80s
                 90s

                 House

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

Hi!

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?

This should do it
select `group`, group_concat(genre, '\n' ) 
from table
group by `group`

Open in new window
