在 mysql 查询中组合结果

Question

I have a mysql-table (lets call it table ) where I store points scored in a game.

| ID | SCORE |
|----|-------|
|1   |10     |
|2   |8      |
|3   |15     |
|4   |9      |

What I'm wondering if there is a neat way to get one row containing the last score (the one with the
highest ID) and the highest score?


Currently I'm doing

SELECT
    score AS last_score,
    (SELECT MAX(score) FROM table) AS best_score
FROM table
ORDER BY id DESC
LIMIT 1

which gives me exactly what I want:

|last_score|best_score|
|----------|----------|
|9         |15        |

But performance wise I wonder if it's better not to have two select :s


I would prefer to do something in the lines of

SELECT
    score AS last_score,
    MAX(score) AS best_score
FROM table
ORDER BY id DESC
LIMIT 1

which gives me the best score, but not the latest.


Any suggestions?

select (SELECT score from purchase ORDER BY id desc LIMIT 1) as last_score, (SELECT MAX(score) as max_score from purchase) as max_score
