Rollup Query Help

[Frank Py]

I found this great rollup query example that uses grouping and sub
totals. Would it be possible to expand on this and include a group
within a group and subtotal each group? For example, parent product then
child product? Help appreciated. Thanks.

SQL:
SELECT
CASE
WHEN (Grouping(CategoryName)=1) THEN 'MainTotal'
ELSE CategoryName
END AS CategoryName,

CASE
WHEN (Grouping(ProductName)=1) THEN 'SubTotal'
ELSE Productname
END AS ProductName,

Sum(UnitPrice) as UnitPrice,
Sum(UnitsinStock) as UnitsInStock

FROM Products
INNER JOIN Categories On
Products.CategoryID = Categories.CategoryID
GROUP BY CategoryName, ProductName WITH ROLLUP

CUBE/ROLLUP will subtotal by whatever columns you specify, so presumably you
need to change the GROUP BY to something like:

....
GROUP BY categoryname, subcategoryname, productname WITH ROLLUP

If this doesn't answer your question please post DDL for this table, post
INSERT statements to generate a few rows of sample data and show your
required result.
