我的表,我想在單列中創建三列,現轉載。
SELECT id,date,type,total
(select (
sum(case when type="Paypal" then total else 0 end)+
sum(case when type="credit" then total else 0 end))+
sum(case when type="Cash" then total else 0 end)) as receiv,
(Select(
sum(case when type="payment" then total else 0 end)) AS payment,
(Select sum(receiv -payment) FROM totals t2
WHERE (t2.date <= t1.date) and (t2.id <= t1.id) order by t1.date) AS remainder
FROM totals t1
group by date, type
order by id,date
- 的SQL代碼下面的查詢? Type =「Paypal,credit,Cash」總計「收到」款項和Type =「付款」款項將被添加到「餘額」欄中。
id | date | type | receiv| payment| remainder
------ | ------ | ------ | ------| ------ | ------
1 | 01.10.2016| Paypal | 50 | 0 | 50
