Question

I have a complex MySQL problem.

SELECT *
FROM banners, content_id_country, languages
    WHERE content_id_country.content_id = banners.id
        AND content_id_country.controller = 'banners'

Gives me a long result back. The result is perfect, there is only one problem.

Some rows are duplicates, so they have only one field changed.

The result will look like:

1 - Title - Text - NL
1 - Title - Text - EN

When I use a “GROUP BY banners.id” one of the two disappears. That is particaly what I am achieving.

The result I would like to get looks like this:
1 – Title – Text – NL, EN

So basically I would like to merge the row, and add a comma.

I hope that this is possible.
