在hivesql中查找唯一计数Postgresql查询

我想获得独特的客户数量。我有postgresql查询的参考。能否将此查询转换为HiveSql

SELECT
    COUNT(user_id) Total_profiles,
    COUNT(distinct user_id) FITLER (WHERE age BETWEEN 18 AND 12) as age_less_than_20
FROM 
    customer_profiles
WHERE 
    profile_date BETWEEN '2020-01-01' AND '2020-12-31'

用例表达式：

SELECT
    COUNT(user_id) Total_profiles,
    COUNT(distinct case when age BETWEEN 18 AND 12 then user_id else null end) as age_less_than_20
FROM 
    customer_profiles
WHERE 
    profile_date BETWEEN '2020-01-01' AND '2020-12-31'

另一种计算不同大小的方法是大小（collect_set（））：
