Hi All,

I have been pulling my hair out over this one.

What we are trying to do is pull sum values for the same item out of three different tables in the same DB (MSSQL '05) – Should be quite straight forward however...

The result should look a bit like below;

item code | initial population value | ordered value | sold value | cost price

The below query is pulling everything correctly except ordered value.

I have a suspicion the below snippet of the statement is to blame for this – the value that return from this below snippet are inflated by many multiples.


LEFT OUTER JOIN
Sys2OrderItems ON Sys2OrderItems.bc_code = BaseListing.Code AND Sys2OrderItems.status = 2
INNER JOIN
Sys2Order ON Sys2OrderItems.order_number = Sys2Order.order_number AND
Sys2Order.order_location = @LocationNumber AND Sys2Order.order_approval_status = 3 AND
Sys2Order.order_status = 3 AND Sys2Order.order_date > @InternalDate


I believe what may be happening is if the Order (Sys2Order) has multiple items (Sys2OrderItems) it is calculating the SUM value by the amount of items in the order to due to the number of rows in Sys2OrderItems for that ordernumber.

I hope this makes sense however been on this all day and may be totally wrong.

Any help greatly appreciated.

Full query code below;



SELECT BaseListing.Code, InitialValues.value AS InitialPopulation, SUM(Sys2InvoiceItems.Quantity) AS Sold,
SUM(Sys2OrderItems.qty) AS recv, Sys1Item.Description, ItemGroupsParent.Name AS PrimaryGroup,
ItemGroupsChild.Name AS ChildGroup, Sys2Item.Cost_Group1, Sys2Item.Cost_Group2,
SUM(Sys2OrderItems.qty) AS Expr1
