A very-very-very quick search for 'ORDER BY RAND' in the MySQL manual
turned up the following at the middle of the documentation of the RAND()
function:
You can't use a column with `RAND()' values in an `ORDER BY'
clause, because `ORDER BY' would evaluate the column multiple
times. In *MySQL* Version 3.23, you can, however, do: `SELECT *
FROM table_name ORDER BY RAND()'
It does say 'in MySQL version 3.23', doesn't it now? :) 3.22 does not
support this syntax.
G'luck,
Peter
