Need help with totals query, in SQL server
I have a table of customer purchases, with the price paid and tax paid for the item. I have a query which will group the number of purchases based on the Month and year, and it works great. See illustration #1 of the result which works great.
However what I need to do is to also display the total of
the purchases per month, plus the total of the taxes paid on all of the purchases made per month. Also I would like the grand total for each month.
I tried doing this using the SUM command but it did not work. Look at Illustration #2 of the desired output which I need. Can someone show me how
to modify my query to display the result shown in Illustration #2. The Grand totals line would also be nice, however my first priority is
to get the monthly totals, TotalPurchasePrice and TotalTaxes. Can someone please help me out with the query?
Table
ID
CustName
PurchaseDate
PurchasePrice
Tax
select YEAR(PurchaseDate) AS Year, MONTH(PurchaseDate) AS Month, COUNT(*) FROM Customers Group By YEAR(PurchaseDate),MONTH(P
ID Year Month Purchases
1 2016 7 3 -- 3 customer purchases occurred during the month of July
2 2016 8 5

What are you using to display/present the results of the query? e.g. SSRS? HTML?
It is possible to get "grand totals" using SQL, but it isn't always wise to do it that way.
try group by rollup

Hi Paul, thanks for the help. I am not using any type of reporting tools like HTML or SSRS.
It sounds like the grand totals might be too difficult with SQL. I tried your query and it works great. Thanks so much !!

SELECT
YEAR(PurchaseDate) AS Year
, MONTH(PurchaseDate) AS Month
, COUNT(*) AS Purchases
, SUM(PurchasePrice) AS TotalPurchasePrice
, SUM(Tax) AS TotalTaxes
FROM Customers
GROUP BY ROLLUP (
YEAR(PurchaseDate)
, MONTH(PurchaseDate)
)
