Nice work but the picture titles and descriptions are really confusing. Other than that, a great photo blog.

Hmm .. easy to do with a few fixed values, a little harder with a random number of items to search for.
But thanks for the pointer

@Tim: this way:

SELECT  a.*
FROM    (
        SELECT  3 id, 1 o
        UNION ALL
        SELECT  1 id, 2 o
        UNION ALL
        SELECT  2 id, 3 o
        ) q
JOIN    a
ON      a.column = q.id
ORDER BY
        o

Is it possible to do
>SELECT *
>FROM a
>WHERE column IN (3, 1, 2)

and get the values back in the list order? MySQL seems to always order ascending – I’m guessing it’s to do with the way it searches the database for the list values
