The way I've accomplished this in the past is to create an extra column,
call it "randNum," populate it with random numbers, then order by that
column.
If you don't care how strong the "randomness" is, you can sort by an
arbitrary column that has a lot of variation, say a foreign key column
ID.
I've also seen the logic moved into the application: select the values
into an array, and randomly traverse the array.
