用户徽章计数，带徽章名称过滤器

社区 数据与报告
3

这是该查询的一个略微修改版本，添加了 badge name 过滤器。badge name 的默认值为 'all badges'。当设置为该值时，将返回所有徽章的结果。如果您将 badge name 设置为特定徽章的名称，则仅返回该徽章的结果。

-- int :posts = 1
-- int :top = 10
-- string :badge_name = all badges

SELECT
username,
COUNT(ub.id) as badge_count
FROM user_badges ub
JOIN users u ON u.id = ub.user_id
JOIN user_stats us
ON us.user_id = ub.user_id
JOIN badges b ON b.id = ub.badge_id
WHERE us.post_count > :posts
AND (u.admin = 'f' AND u.moderator = 'f')
AND CASE
        WHEN 'all badges' = :badge_name
            THEN true
        ELSE b.name = :badge_name
    END
GROUP BY u.username
ORDER BY badge_count DESC
