SQL sub total and final total query

I need to extend my sql query that currently returns sub totals. Is there a way to return both sub totals and grand total with this query:

SELECT oi.PurchaseID,
SUM(oi.Quanity * CONVERT(decimal(18,2), p.ItemPrice)) AS sub_total
FROM vwPurchaseType oi
JOIN tblColor p ON p.ColorID = oi.ColorID
WHERE oi.UserID = 1
GROUP BY oi.PurchaseID

Can I create another alias for grand total? I've tried a few different ways and so far I'm leaning toward INSERT the sub_totals into a temp table and returning the value in a stored proc.

Any advice is much appreciated!

You don't specify the database you are using, but many databases support the with rollup clause for the group by:

SELECT oi.PurchaseID,
       SUM(oi.Quanity * CONVERT(decimal(18,2), p.ItemPrice)) AS sub_total
FROM vwPurchaseType oi JOIN
     tblColor p
     ON p.ColorID = oi.ColorID
WHERE oi.UserID = 1
GROUP BY oi.PurchaseID WITH ROLLUP;

This will add an additional row where the PurchaseId is NULL. That has the total in it.
