Mysql MAX值和Last Record同时出现

Question

如果你有2个字段的表：

ID | AMOUNT

如何使用1个查询获得最大值（AMOUNT）和最后输入记录的数量（按ID desc排序）？

感谢你

Answer 1

select amount as last_amount, 
      (select max(amount) from your_table) as max_amount
from your_table
order by id desc
limit 1

Answer 2

你可以这样做：

SELECT
    (SELECT MAX(amount) FROM table) as Max,
    (SELECT amount FROM table ORDER BY id DESC LIMIT 1) as Last
