I want to sort the following data items in the order they are presented below (numbers 1-12):
1 2 3 4 5 6 7 8 9 10 11 12
However, my query - using
I had some good results with
SELECT alphanumeric, integer FROM sorting_test ORDER BY CAST(alphanumeric AS UNSIGNED), alphanumeric ASC
I hate this, but this will work
order by lpad(name, 10, 0) <-- assuming maximum string length is 10
<-- you can adjust to a bigger length if you want to
Try this For ORDER BY DESC
SELECT * FROM testdata ORDER BY LENGHT(name) DESC, name DESC
People use different tricks to do this. I Googled and find out some results each follow different tricks. Have a look at them:
Edit:
I have just added the code of each link for future visitors.

Hope this helps
Just do this:
SELECT * FROM table ORDER BY column `name`+0 ASC
Appending the +0 will mean that:
0, 10, 11, 2, 3, 4
becomes :
0, 2, 3, 4, 10, 11
I know this post is closed but I think my way could help some people. So there it is :
My dataset is very similar but is a bit more complex. It has numbers, alphanumeric data :

I would like to have the '-' symbol at first, then the numbers, then the text.
So I go like this :
SELECT name, (name = '-') boolDash, (name = '0') boolZero, (name+0 > 0) boolNum
FROM table
ORDER BY boolDash DESC, boolZero DESC, boolNum DESC, (name+0), name
The result should be something :
-
0
1
2
3
4
5
10
13
99
102
Chair
Dog
Table
Windows
The whole idea is doing some simple check into the SELECT and sorting with the result.
