Cara menghasilkan 5 angka acak dalam prosedur tersimpan mysql

Jika rentang Anda kecil, dan Anda memiliki tabel bilangan bulat , pendekatan naif mungkin berhasil:

SELECT GROUP_CONCAT(i SEPARATOR '|')
  FROM (  SELECT i
            FROM (  SELECT i
                      FROM integers
                     WHERE i BETWEEN 1 AND 50
                  ORDER BY RAND()
                     LIMIT 5) sort_these_five
        ORDER BY i) concat_these_five;
