SQL query for calculating mtd, ytd values
提问by Hashir Rizwan
I have a table with columns ID, Title, Date, Amount.
我有一个列有ID, Title, Date,的表Amount。
I need to get MTD, YTD amount values against each transaction based on Title, Date.
我需要得到MTD，YTD量值针对基于每笔交易Title，Date。
Is there anyone who had done this before?
有没有人以前做过这个？

Select t.title, t.Date,
Sum(y.Amount) YTD,
Sum(m.Amount) MTD
From table t
join table y
on y.Title = t.Title
and datediff(year, y.Date, t.Date) = 0
and y.Date <= t.Date
join table m
on m.Title = t.Title
and datediff(month, m.Date, t.Date) = 0
and m.Date <= t.Date
Group by t.title, t.Date

SELECT ID,
Title,
Date,
Amount,
MTD = SUM(Amount) OVER (PARTITION BY Title, DATEADD(MONTH, DATEDIFF(MONTH, 0, [Date]), 0)),
YTD = SUM(Amount) OVER (PARTITION BY Title, DATEADD(YEAR, DATEDIFF(YEAR, 0, [Date]), 0))
FROM [a_table]
