Question

我如何获得相同的结果，但不在mysql中使用“ limit”？

SELECT user_id
FROM user_interest
GROUP BY user_id
HAVING COUNT(user_id)
ORDER BY (COUNT(user_id)) DESC
LIMIT 2

Answer 1

如果您不想使用限制，这里有一些建议

select t2.user_id 
from (
    select row_number() over (order by t1.ct desc) as rn, t1.userid 
    from (
        SELECT user_id, COUNT(user_id) as ct
        FROM user_interest
        GROUP BY user_id
        HAVING COUNT(user_id)
    )t1 
) as t2 where t2.rn < 3

在不使用“ limit”的情况下获得相同的结果（MySQL）
