Answer 1

在

上添加要订购的列

SELECT id, name, 1 as unionOrder FROM users WHERE id !=2 
UNION 
SELECT id, name, 2 as unionOrder FROM users2 WHERE id != 3

ORDER BY unionOrder 

Answer 2

您也可以这样做

(SELECT id, name 
  FROM users 
  WHERE id !=2
ORDER BY id)
UNION ALL
(SELECT id, name 
  FROM users2 
  WHERE id != 3
  ORDER BY id);
