選擇子查詢中的UNION問題

Question

在下面的代碼中，如何在UNION中結合使用MRR_Created和MRR_Destroyed，以便僅顯示下一個數字？ 現在查詢是正確的，但我不需要分別查看增加/減少。

 select account.email, account.vip, datediff(now(), account.date_created) AS Age,
(select sum(account_subscription.next_invoice_price) as ActiveMRR
from account_subscription
where account_subscription.status = 'active'
and account_subscription.acctid = account.acctid
) as MRR,
(select count(account_subscription.subid) as Churn
from account_subscription
where account_subscription.date_created between DATE_ADD(NOW(), INTERVAL -2880 MINUTE) and NOW()
and account_subscription.date_closed between DATE_ADD(NOW(), INTERVAL -2880 MINUTE) and NOW()
and account_subscription.acctid = account.acctid
) as Churn,

(select sum(account_subscription.next_invoice_price) as MRR
from account_subscription
where date(account_subscription.date_created) = date(curdate())
and account_subscription.acctid = account.acctid
) as MRR_Created,
(select sum(account_subscription.next_invoice_price) as MRR
from account_subscription
where date(account_subscription.date_closed) = date(curdate())
and account_subscription.acctid = account.acctid
) as MRR_Destroyed,

 concat("https://sitetest.com?ACCTID=",account.acctid) as URL

 from account
 where account.status = 'active'
 and (
account.type in ('affiliate', 'customer', 'customer_freetrial', 'customer_duplicate', 'customer_match')
or account.type is null
)
 group by account.acctid
 order by MRR desc

不知道您是否真的需要UNION。 嘗試更換

(select sum(account_subscription.next_invoice_price) as MRR
from account_subscription
where date(account_subscription.date_created) = date(curdate())
and account_subscription.acctid = account.acctid
) as MRR_Created,
(select sum(account_subscription.next_invoice_price) as MRR
from account_subscription
where date(account_subscription.date_closed) = date(curdate())
and account_subscription.acctid = account.acctid
) as MRR_Destroyed,

與

(select sum(account_subscription.next_invoice_price) as MRR
from account_subscription
where (date(account_subscription.date_created) = date(curdate())
or date(account_subscription.date_closed) = date(curdate()))
and account_subscription.acctid = account.acctid
) as MRR_Created,

希望這可以幫助！
