选择子查询计数，大小写，总和

Question

您能帮我吗，我有问题，这是我的代码。

SELECT tglkadaluarsa - now() AS date_ratio, CASE
WHEN tglkadaluarsa - now() < '0 days' THEN 'Has Expired'
WHEN tglkadaluarsa - now() <= '180 days' THEN 'Expire <= 6 Month'
WHEN tglkadaluarsa - now() <= '365 days' THEN 'Expire <= 1 Year'
WHEN tglkadaluarsa - now() <= '725 days' THEN 'Expire <= 2 Year'
WHEN tglkadaluarsa - now() > '725 days' THEN 'Expire More 2 Year'
WHEN tglkadaluarsa is null THEN 'Expire Not Updated'
END AS range_expire, COUNT(*) FROM sdm.ms_unit
GROUP BY date_ratio, range_expire ORDER BY date_ratio

我想获取range_expire并进行计数，但是基于范围的计数数据总和到期，然后我使用它，但是我不知道要基于范围到期的总和，我使用此代码

SELECT a.range_expire FROM (SELECT tglkadaluarsa - now() AS date_ratio
WHEN tglkadaluarsa - now() < '0 days' THEN 'Has Expire'
WHEN tglkadaluarsa - now() <= '180 days' THEN 'Expire <= 6 Month'
WHEN tglkadaluarsa - now() <= '365 days' THEN 'Expire <= 1 Year'
WHEN tglkadaluarsa - now() <= '725 days' THEN 'Expire <= 2 Year'
WHEN tglkadaluarsa - now() > '725 days' THEN 'Expire More 2 Year'
WHEN tglkadaluarsa is null THEN 'Expire Not Updated'
END AS range_expire, COUNT(*) FROM sdm.ms_unit GROUP BY date_ratio, range_expire
ORDER BY range_expire) a GROUP BY range_expire ORDER BY range_expire

SELECT range_expire,sum_range_expire FROM (

CASE

    WHEN tglkadaluarsa - now() > '725 days' THEN 'Expire More 2 Year'
    WHEN tglkadaluarsa is null THEN 'Expire Not Updated'
END AS range_expire, 
SUM(CASE 
    WHEN tglkadaluarsa - now() < '0 days' THEN 1
    WHEN tglkadaluarsa - now() <= '180 days' THEN 1
    WHEN tglkadaluarsa - now() <= '365 days' THEN 1
    WHEN tglkadaluarsa - now() <= '725 days' THEN 1
    WHEN tglkadaluarsa - now() > '725 days' THEN 1
    WHEN tglkadaluarsa is null THEN 1
    ELSE 0
END) AS sum_range_expire, 

SUM(CASE WHEN tglkadaluarsa - now() < '0 days' THEN 1 ELSE 0 END) AS 'Has_Expire'
SUM(CASE WHEN tglkadaluarsa - now() <= '180 days' THEN 1 ELSE 0 END) AS Expire_Before_6_Month
SUM(CASE WHEN tglkadaluarsa - now() <= '365 days' THEN 1 ELSE 0 END) AS Expire_Before_1_Month
