MYSQL - SUM of a column based on common value in other column

Question

I\'m stuck on crafting a MySQL query to solve a problem. I\'m trying to iterate through a list of \"sales\" where I\'m trying to sort the Customer IDs listed by their total accu

Answer 1

You need to GROUP BY your customer id:

SELECT CustomerID, SUM(PurchasePrice) AS PurchaseTotal
FROM sales
GROUP BY CustomerID;

Answer 2

Select CustomerID, sum(PurchasePrice) as PurchaseTotal FROM sales GROUP BY CustomerID ORDER BY PurchaseTotal ASC;

Answer 3

Just by having a little Google search, I managed to find a page doing exactly what you're doing (I think). I have tailored the query below to fit your circumstance.

SELECT CustomerID, SUM(PurchasePrice) AS PurchaseTotal
FROM sales
GROUP BY CustomerID
ORDER BY PurchaseTotal ASC
