I have a basic database for a retail store with 4 tables, one of which stores Order info, one that stores Product info and one that stores Supplier info.
I am trying to run a query that will display total sum of stock sold figure (in dollars) with a GROUP BY supplier with ROLL UP. I have a feeling that SUM should be in the code but I can't find where to put it, so far I have this:
SELECT ORDERS.OrderPrice, PRODUCT.SupplierID, SUPPLIER.SupplierName FROM ((ORDERS INNER JOIN PRODUCT ON ORDERS.ProductID = PRODUCT.ProductID) INNER JOIN SUPPLIER ON PRODUCT.SupplierID = SUPPLIER.SupplierID) GROUP BY SupplierName WITH ROLLUP;
The database can be viewed on DB Fiddle here:
Any ideas? Thanks
