My SQL 4.1.25
I am totally stumped with this one.
I have a table in which one of the columns is an integer from 0~10.
I am trying to split that it into two groups. 1-5 and 0 + 6-10 and order them firstly group 0 + 6-10 then group 1-5 with each group randomised.
So basically I need to see something like this
10
7
8
0
7
6
9
6
0
10
2
4
5
2
5
3
1
Any ideas please

I came up with the following
ORDER BY (my_number = 0 OR my_number > 5) DESC, RAND(),my_number ASC, RAND()
Do you know a better/alternate way?

Doesn't that work? It looks like it should, and is exactly how I would do it . . .

Yes, in fact it works better than I thought it would.
I was just asking to find out if anyone would do it a different way. More than one way to skin a cat and all that.
I feel reasured that you said that's the way you would do it :)
Thanks
