Question

我想找到我最近30天的值与之前最近30天的值的不同百分比。我已经有了最近30天的总值。如何获得前30天的总和？

这是用于选择最近30天总和的查询。

SELECT SUM(paymentAmount) as usd30day
FROM `tbl_pi_payment` 
WHERE currencyCode = 'USD' and renewalDate >= NOW() - INTERVAL 30 DAY

示例：今天是10月25日。我有10月25日至9月26日的值总和。现在我需要9月26日至8月25日的值之和

Answer 1

您可以在下面尝试-

SELECT SUM(case when renewalDate >= NOW() - INTERVAL 30 DAY paymentAmount else 0 end) as usd30day ,
SUM(case when renewalDate >= NOW() - INTERVAL 60 DAY and renewalDate < NOW() - INTERVAL 30 DAY paymentAmount else 0 end) as usd60day
FROM tbl_pi_payment
WHERE currencyCode = 'USD'

Answer 2

基于renewalDate

获取以前的交易

select sum(case when renewalDate >= NOW() - INTERVAL 30 DAY then paymentAmount else 0 end) as usd30day 
    , sum(case when datediff(now() - renewalDate) <= 30 then paymentAmount else 0 end) as usd30prevday 
from tbl_pi_payment 
where 
    currencyCode = 'USD'

Answer 3

SELECT datediff(NOW(), renewalDate) % 30 as every30day, SUM(paymentAmount) as usd30day
FROM `tbl_pi_payment`
WHERE currencyCode = 'USD' 
GROUP BY datediff(NOW(), renewalDate) % 30

SQL查询以获取最近30天之前的记录（不是最近30天）
