    To sort in descending order, just add “DESC” to the end of your ORDER BY:

    SELECT `sid`
FROM `mytable`
ORDER BY SUBSTRING(`sid`, 10, length(`sid`)) DESC

    However, if the values of sid are of different lengths, you are probably going to want to cast the values to a numeric type before sorting:

    SELECT `sid`
FROM `mytable`
ORDER BY CAST(SUBSTRING(`sid`, 10, length(`sid`)) AS SIGNED) DESC
