Microsoft SQL Sub Query - How do I use a "where" clause on a "Sum" column
Posted on 2007-11-29
I am using Microsoft SQL Server 2000.
I have the following query below am using the query below:
Select C.ComponentID,
(SELECT SUM(IsNull(OrderQuantity, 0)) - SUM(IsNull(ReceiveQuantity
FROM PurchaseOrderItemTable I
WHERE C.ComponentID = I.ComponentID AND I.ItemStatusID IN (0, 2)) AS ComponentsOnOrder,
(SELECT SUM(IsNull(Quantity * PT.ProductionQuantity, 0))
FROM ProductionItemTable P LEFT OUTER JOIN
ProductionTable PT ON PT.ProductionID = P.LinkID
WHERE C.ComponentID = P.ItemLinkID AND P.ItemTypeID = 1 AND PT.StatusID = 1) AS ComponentsAllocated
From ComponentTable C
where C.StockHolding = 1
and
(C.StockOnHand - ComponentsAllocated) + ComponentsOnOrder) < C.ReorderLevel
The problem is that I am unable to use the "ComponentsAllocated" or "ComponentsOnOrder" in my final "Where" clause as I get the error message :
"Server: Msg 207, Level 16, State 3, Line 1
Invalid column name 'ComponentsAllocated'.
Server: Msg 207, Level 16, State 1, Line 1
Invalid column name 'ComponentsOnOrder'."
I know the query works as if I remove the last two line all is OK.
The query is used to retun a list of "ComponentID"s from the ComponentTable and the two sub-queries are calculating the Components OnOrder and the Components Allocated from the respective tables for Each Component.
The last two lines of the query only return components that need to be re-ordered.
Any help would be much appreciated.

You are using table alias names rather than column names. Try:
Select C.ComponentID,
(SELECT SUM(IsNull(OrderQuantity, 0)) - SUM(IsNull(ReceiveQuantity
FROM PurchaseOrderItemTable I
WHERE C.ComponentID = I.ComponentID AND I.ItemStatusID IN (0, 2)) AS Table1,
(SELECT SUM(IsNull(Quantity * PT.ProductionQuantity, 0)) AS ComponentsAllocated
FROM ProductionItemTable P LEFT OUTER JOIN
ProductionTable PT ON PT.ProductionID = P.LinkID
WHERE C.ComponentID = P.ItemLinkID AND P.ItemTypeID = 1 AND PT.StatusID = 1) AS Table2
From ComponentTable C
where C.StockHolding = 1
and
(C.StockOnHand - ComponentsAllocated) + ComponentsOnOrder) < C.ReorderLevel
Select C.ComponentID,
(SELECT SUM(IsNull(OrderQuantity, 0)) - SUM(IsNull(ReceiveQuantity
FROM PurchaseOrderItemTable I
WHERE C.ComponentID = I.ComponentID AND I.ItemStatusID IN (0, 2)) AS Table1,
(SELECT SUM(IsNull(Quantity * PT.ProductionQuantity, 0)) AS ComponentsAllocated
FROM ProductionItemTable P LEFT OUTER JOIN
ProductionTable PT ON PT.ProductionID = P.LinkID
WHERE C.ComponentID = P.ItemLinkID AND P.ItemTypeID = 1 AND PT.StatusID = 1) AS Table2
From ComponentTable C
where C.StockHolding = 1
and
(C.StockOnHand - ComponentsAllocated) + ComponentsOnOrder) < C.ReorderLevel
You cant reference subqueries in a WHERE clause.
subqueries are processed row by row returned, the where clause designates the criteria to return the row. You will either have to puyt the whoel subqueries in the where clause or find a way to move the subqueries to JOINs.

Try this:
Select C.ComponentID, ComponentsAllocated.Allocated, ComponentsOnOrder.OnOrder
From ComponentTable C
LEFT OUTER JOIN
(SELECT P.ItemLinkID, SUM(IsNull(Quantity * PT.ProductionQuantity, 0)) AS Allocated
FROM ProductionItemTable P
LEFT OUTER JOIN
ProductionTable PT ON PT.ProductionID = P.LinkID
WHERE P.ItemTypeID = 1 AND PT.StatusID = 1)
AS ComponentsAllocated ON C.ComponentID = ComponentsAllocated.ItemLinkID
LEFT OUTER JOIN
(SELECT I.ComponentID, SUM(IsNull(OrderQuantity, 0)) - SUM(IsNull(ReceiveQuantity, 0)) AS OnOrder
FROM PurchaseOrderItemTable I WHERE I.ItemStatusID IN (0, 2))
AS ComponentsOnOrder ON C.ComponentID = ComponentsOnOrder.ComponentID
where C.StockHolding = 1
and
(C.StockOnHand - ComponentsAllocated.Allocated) + ComponentsOnOrder.OnOrder) < C.ReorderLevel
What you usually do is wrap the whole thing as another subquery like so
SELECT * FROM
(
Select C.ComponentID,
(SELECT SUM(IsNull(OrderQuantity, 0)) - SUM(IsNull(ReceiveQuantity, 0))
FROM PurchaseOrderItemTable I
WHERE C.ComponentID = I.ComponentID AND I.ItemStatusID IN (0, 2)) AS ComponentsOnOrder,
(SELECT SUM(IsNull(Quantity * PT.ProductionQuantity, 0))
FROM ProductionItemTable P LEFT OUTER JOIN
ProductionTable PT ON PT.ProductionID = P.LinkID
WHERE C.ComponentID = P.ItemLinkID AND P.ItemTypeID = 1 AND PT.StatusID = 1) AS ComponentsAllocated
From ComponentTable C
where C.StockHolding = 1
) DATA
WHERE (C.StockOnHand - ComponentsAllocated) + ComponentsOnOrder < C.ReorderLevel
Apart from a couple of minor syntax changes this is spot on! thanks alot...
I have detailed below the final query below for future ee reference.
Thanks again
