question

I am trying to calculate a pct of total in a query. The example below uses Adventure works db and what I am trying to do is calculate a percentage of ttl sales for each item in the territory. So Item A has a total Sales of 100 Territory x sold 10 of the 100 A Items so the pct of ttl calculation should be 10% or .1 Here is the Adventure Works DB Simulation `use AdventureWorks select SUM(d.orderqty)ITEM_TRTRY_SLS, p.ProductID` into #ITEMSALES from Sales.SalesOrderHeader h join Sales.SalesOrderDetail d on h.salesorderid = d.salesorderid join Production.Product p on p.ProductID = d.ProductID `group by p.ProductID` select * from #ITEMSALES where productid = 777 --all sales = 678 select SUM(d.orderqty)ITEM_TRTRY_SLS, (SUM(d.orderqty) /(select i.ITEM_TRTRY_SLS from #ITEMSALES i where i.ProductID = p.ProductID)) as pct_of_ttl, p.ProductID, h.TerritoryID from Sales.SalesOrderHeader h join Sales.SalesOrderDetail d on h.salesorderid = d.salesorderid join Production.Product p on p.ProductID = d.ProductID where p.productid = 777 group by p.ProductID, h.TerritoryID -- territory 1 should be .28466 ![alt text][1] [1]: http://
