如何在PostgreSQL中使用Group By for Range？

我在AWS Timeseries上有一张如下表：

跟踪标识 度量值：：varchar 度量值：：bigint 度量单位名称 269 - 48 年龄 269 男性 - 性别 这应该做到：

---

如果您不想使用

FILTER

子句，当然可以使用

SUM（如果性别为'Male'，则1 ELSE 0 END）

结构。

！非常感谢你！

SELECT
    CASE 
        WHEN age BETWEEN 0 and 12 THEN '0 - 12'
        WHEN age BETWEEN 13 and 17 THEN '13 - 17'
        ...
    END as age_range,
    COUNT(*) FILTER (WHERE gender = 'Male') as male_count,
    COUNT(*) FILTER (WHERE gender = 'Female') as female_count
FROM (
    SELECT
        tracking_id,
        MAX(measure_value_gender) as gender,
        MAX(measure_value_age) as age
    FROM mytable
    GROUP BY tracking_id
) s
GROUP BY age_range
