MySQL ORDER BY rand(), name ASC

Question

I would like to take a database of say, 1000 users and select 20 random ones (ORDER BY rand(),LIMIT 20) then order the resulting set by the names.

Answer 1

Use a subquery:

SELECT * FROM (
    SELECT * FROM users ORDER BY RAND() LIMIT 20
) u
ORDER BY name

or a join to itself:

SELECT * FROM users u1
INNER JOIN (
    SELECT id FROM users ORDER BY RAND() LIMIT 20
) u2 USING(id)
ORDER BY u1.name
