我有以下MySQL查询:
SELECT user_id, score, time
FROM tests_1 T
WHERE T.score = (
SELECT MAX(T2.score)
FROM tests_1 T2
WHERE T2.user_id = T.user_id
)
ORDER BY score DESC, time ASC;
如何在'users'表中添加'users'列在users.user_id = tests_1.user_id?

试试这个:
SELECT T.user_id, U.username, T.score, T.time
FROM tests_1 T
JOIN users U on U.user_id = T.user_id
WHERE T.score = (
SELECT MAX(T2.score)
FROM tests_1 T2
WHERE T2.user_id = T.user_id
)
ORDER BY T.score DESC, T.time ASC;

加入吧。
SELECT T.user_id, T.score, T.time, u.username
FROM tests_1 T
JOIN users u ON u.user_id = T.user_id
WHERE T.score = (
SELECT MAX(T2.score)
FROM tests_1 T2
WHERE T2.user_id = T.user_id
)
ORDER BY T.score DESC, T.time ASC;

SELECT user_id, score, time, U.username
FROM tests_1 T JOIN users U
ON T.user_id = U.user_id
WHERE T.score = (
SELECT MAX(T2.score)
FROM tests_1 T2
WHERE T2.user_id = T.user_id
)
ORDER BY score DESC, time ASC;
