Yesterday's Question of the Day (by Steve Jones - SSC Editor)

Getting Subtotals

I am testing some aggregations and have this setup code:

CREATE TABLE ProductSales ( SaleID INT IDENTITY(1,1) NOT NULL CONSTRAINT ProductSalesPK PRIMARY KEY , ProductCat VARCHAR(100) , ProductName VARCHAR(100) , SaleDate DATETIME , SaleTotal NUMERIC(10,2) ) GO INSERT dbo.ProductSales (ProductCat, ProductName, SaleDate, SaleTotal) VALUES ('Laptop', 'HP Spectre', '2020-01-02', 100 ), ('Laptop', 'Lenovo Thinkpad', '2020-01-05', 200 ), ('Laptop', 'AlienWare', '2020-02-02', 300 ), ('Mobile', 'iPhone', '2020-02-12', 50 ), ('Mobile', 'Samsung Galaxy', '2020-03-12', 100 ), ('Watch', 'Apple Watch', '2020-02-22', 200 ), ('Watch', 'Garmin Forerunner', '2020-02-23', 400 ) GO

I want to run a sum by category and month showing the category and month, with

total for that category for each month with sales
total for the category
total sales

I want no extra rows. I have this code:

SELECT ps.ProductCat , MONTH(saledate) , SUM(ps.SaleTotal) AS TotalSales FROM dbo.ProductSales AS ps GROUP BY xxx(ps.ProductCat, MONTH(saledate))

Which keyword(s) replaces the XXXX and gives me less rows in the result set?

Answer: ROLLUP

Explanation: Only CUBE and ROLLUP are valid here. ROLLUP will return less results. Ref: GROUP BY - https://docs.microsoft.com/en-us/sql/t-sql/queries/select-group-by-transact-sql?view=sql-server-ver15

Adding NOT NULL to column with existing rows causes page bloat - Hi, I'd like to know why the page count is almost exactly doubled for a table with existing rows, having updated the column in question with values so none are NULL (this step also causes double pages, but I understand why, fragmentation becomes 99% so i REBUILD clustered index), then running ALTER TABLE ...
