MySQL 计数不同

Question

我正在尝试收集昨天在我的 cp 中的不同访问次数，然后计算它们。

SELECT
    DISTINCT `user_id` as user,
    `site_id` as site,
    `ts` as time
FROM
    `cp_visits`
WHERE
    ts >= DATE_SUB(NOW(), INTERVAL 1 DAY)

由于某种原因，这会使用相同的站点 ID 提取多个结果....我如何仅提取和计算不同的 site_id cp 登录？

Answer 1

 Select
     Count(Distinct user_id) As countUsers
   , Count(site_id) As countVisits
   , site_id As site
 From cp_visits
 Where ts >= DATE_SUB(NOW(), INTERVAL 1 DAY)
 Group By site_id
