Hi,

I've a database who contain some datas in that form:

icon(name, size, tag)
(myicon.png, 16, 'twitter')
(myicon.png, 32, 'twitter')
(myicon.png, 128, 'twitter')
(myicon.png, 256, 'twitter')
(anothericon.png, 32, 'facebook')
(anothericon.png, 128, 'facebook')
(anothericon.png, 256, 'facebook')

So as you see it, the name field is not uniq I can have multiple icons with the same name and they are separated with the size field. Now in PHP I have a query that get ONE icon set, for example :

$dbQueryIcons = mysql_query("SELECT * FROM pl_icon WHERE tag LIKE '%".$SEARCH_QUERY."%' GROUP BY name ORDER BY id DESC LIMIT ".$firstEntry.", ".$CONFIG['icon_per_page']."") or die(mysql_error());

With this example if $tag contain 'twitter' it will show ONLY the first SQL data entry with the tag 'twitter', so it will be :

(myicon.png, 16, 'twitter')

This is what I want, but I would prefer the '128' size by default. Is this possible to tell SQL to send me only the 128 size when existing and if not another size ?

In an another question someone give me a solution with the GROUP BY but in this case that don't run because we have a GROUP BY name. And if I delete the GROUP BY, it show me all size of the same icons.

Thanks !
