Question

Using alias in subquery

Asked by: xkitzed

Hello,
 I am trying to to execute the following query in MS SQL Server:

SELECT tblProducts.ProductName AS [Product Name],
SUM(tblOrderDetails.Quantity) AS [Quantity Sold],
SUM(tblOrderDetails.Quantity * tblProducts.UnitPrice) As [Total Cost]
FROM tblOrders INNER JOIN tblOrderDetails ON tblOrders.OrderID = tblOrderDetails.OrderID
               INNER JOIN tblProducts ON tblOrderDetails.ProductID = tblProducts.ProductID
WHERE (tblOrders.OrderDate >= '2/25/2004') AND (tblOrders.OrderDate <= '2/27/2004')
      AND tblOrders.OrderID IN
      (SELECT tblOrders.OrderId,
       sum(tblOrderDetails.Quantity * tblProducts.UnitPrice) AS [Cost],
       sum(tblPayments.PaymentAmount) AS [Paid]
       from tblOrders INNER JOIN tblOrderDetails on tblOrders.OrderID = tblOrderDetails.OrderId
                      INNER JOIN tblPayments ON tblOrders.OrderID = tblPayments.OrderID
       WHERE [Cost] <= [Paid])                        
GROUP BY tblProducts.ProductName

But SQL server sayd it cannot find the Column Names Cost or Paid (used int the WHERE clause of the subquery).  

I am new  SQL user, and any help appreciated. thanks.

     Because you are trying to filter SUMs that are managed by a GROUP BY, you need to do the filtering in a HAVING instead of a WHERE.  

     Your sub-select doesn't have its own independant GROUP BY; it probably should group on "tblOrders.OrderId".  

     Try adding the GROUP BY and then using a HAVING clause to filter.  If it still doesn't work, then copy your literal equasions you are using into the HAVING clause.

Is this what you mean?

SELECT dbo.tblProducts.ProductName AS [Product Name],
SUM(dbo.tblOrderDetails.Quantity) AS [Quantity Sold],
SUM(dbo.tblOrderDetails.Quantity * dbo.tblProducts.UnitPrice) As [Total Cost]
FROM dbo.tblOrders INNER JOIN dbo.tblOrderDetails ON dbo.tblOrders.OrderID = dbo.tblOrderDetails.OrderID
                   INNER JOIN dbo.tblProducts ON dbo.tblOrderDetails.ProductID = dbo.tblProducts.ProductID
GROUP BY dbo.tblProducts.ProductName
HAVING (dbo.tblOrders.OrderDate >= '2/25/2004') AND (dbo.tblOrders.OrderDate <= '2/27/2004')
      AND dbo.tblOrders.OrderID IN
      (SELECT dbo.tblOrders.OrderId,
       sum(dbo.tblOrderDetails.Quantity * dbo.tblProducts.UnitPrice) AS [Cost],
       sum(dbo.tblPayments.PaymentAmount) AS [Paid]
       FROM dbo.tblOrders INNER JOIN dbo.tblOrderDetails on dbo.tblOrders.OrderID = dbo.tblOrderDetails.OrderId
                          INNER JOIN dbo.tblPayments ON dbo.tblOrders.OrderID = dbo.tblPayments.OrderID
       GROUP BY tblOrders.OrderID      
       HAVING ([Cost] <= [Paid]))

I tsill gives an error :

Would you try this:

SELECT tblProducts.ProductName AS [Product Name],
SUM(tblOrderDetails.Quantity) AS [Quantity Sold],
SUM(tblOrderDetails.Quantity * tblProducts.UnitPrice) As [Total Cost]
FROM tblOrders INNER JOIN tblOrderDetails ON tblOrders.OrderID = tblOrderDetails.OrderID
               INNER JOIN tblProducts ON tblOrderDetails.ProductID = tblProducts.ProductID
WHERE (tblOrders.OrderDate >= '2/25/2004') AND (tblOrders.OrderDate <= '2/27/2004')
      AND tblOrders.OrderID IN
      (SELECT tblOrders.OrderId,
       sum(tblOrderDetails.Quantity * tblProducts.UnitPrice) AS [Cost],
       sum(tblPayments.PaymentAmount) AS [Paid]
       from tblOrders INNER JOIN tblOrderDetails on tblOrders.OrderID = tblOrderDetails.OrderId
                      INNER JOIN tblPayments ON tblOrders.OrderID = tblPayments.OrderID
         GROUP BY  tblOrders.OrderId
 HAVING  sum(tblOrderDetails.Quantity * tblProducts.UnitPrice) <=  sum(tblPayments.PaymentAmount)  )                        
GROUP BY tblProducts.ProductName

the above query resulted in the folowing error:
Server: Msg 116, Level 16, State 1, Line 1
Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.

I am not familiar with the EXISTS statement.

This will work, too.

SELECT tblProducts.ProductName AS [Product Name],
SUM(tblOrderDetails.Quantity) AS [Quantity Sold],
SUM(tblOrderDetails.Quantity * tblProducts.UnitPrice) As [Total Cost]
FROM tblOrders INNER JOIN tblOrderDetails ON tblOrders.OrderID = tblOrderDetails.OrderID
               INNER JOIN tblProducts ON tblOrderDetails.ProductID = tblProducts.ProductID
WHERE (tblOrders.OrderDate >= '2/25/2004') AND (tblOrders.OrderDate <= '2/27/2004')
      AND tblOrders.OrderID IN
      (SELECT tblOrders.OrderId
       from tblOrders INNER JOIN tblOrderDetails on tblOrders.OrderID = tblOrderDetails.OrderId
                     INNER JOIN tblPayments ON tblOrders.OrderID = tblPayments.OrderID
         GROUP BY  tblOrders.OrderId
 HAVING  sum(tblOrderDetails.Quantity * tblProducts.UnitPrice) <=  sum(tblPayments.PaymentAmount)  )                        
GROUP BY tblProducts.ProductName

Hi:
    The error you posted:

the above query resulted in the folowing error:
Server: Msg 116, Level 16, State 1, Line 1
Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.

is referring to the list of things in the SELECT of your SUBSELECT.  To satisfy your test "tblOrders.OrderID IN " you only need  "tblOrders.OrderId" in the sub-select.  In fact, the rest of the stuff causes the error.
     What you included is useful for debugging, for instance, if you needed to lift the sub-select out to look at what it is doing.  But when it is really being used, the rule is that you can only select one thing.  But that doesn't stop you from filtering with other things.

IC
 

Im am trying this one:
SELECT tblProducts.ProductName AS [Product Name],
SUM(tblOrderDetails.Quantity) AS [Quantity Sold],
SUM(tblOrderDetails.Quantity * tblProducts.UnitPrice) As [Total Cost]
FROM tblOrders INNER JOIN tblOrderDetails ON tblOrders.OrderID = tblOrderDetails.OrderID
               INNER JOIN tblProducts ON tblOrderDetails.ProductID = tblProducts.ProductID
               INNER JOIN (SELECT tblOrders.OrderId as OrderId
                           FROM tblOrders INNER JOIN tblOrderDetails on tblOrders.OrderID = tblOrderDetails.OrderId
                                          INNER JOIN tblPayments ON tblOrders.OrderID = tblPayments.OrderID
                               GROUP BY  tblOrders.OrderId
                               HAVING  sum(tblOrderDetails.Quantity * tblProducts.UnitPrice) <=  sum(tblPayments.PaymentAmount)  ) as ttemp
               ON (ttemp.OrderId = tblOrders.OrderId)  
WHERE (tblOrders.OrderDate >= '2/25/2004') AND (tblOrders.OrderDate <= '2/27/2004')
GROUP BY tblProducts.ProductName

But now it complains as such:
Server: Msg 107, Level 16, State 3, Line 1
The column prefix 'tblProducts' does not match with a table name or alias name used in the query.

I dont know why because the table name is as it should be.

FROM tblOrders INNER JOIN tblOrderDetails ON tblOrders.OrderID = tblOrderDetails.OrderID

                                                INNER JOIN tblPayments ON tblOrders.OrderID = tblPayments.OrderID

Run this query separetely to verify results.

SELECT tblOrders.OrderId as OrderId , sum(tblOrderDetails.Quantity * tblProducts.UnitPrice) , sum(tblPayments.PaymentAmount)
                                 FROM tblOrders INNER JOIN tblOrderDetails on tblOrders.OrderID = tblOrderDetails.OrderId
                                                INNER JOIN tblPayments ON tblOrders.OrderID = tblPayments.OrderID
                                             INNER JOIN tblProducts ON tblOrderDetails.ProductID = tblProducts.ProductID
                                 GROUP BY  tblOrders.OrderId
                                 HAVING  sum(tblOrderDetails.Quantity * tblProducts.UnitPrice) <=  sum(tblPayments.PaymentAmount)

as it turned out, the results were not as I expected, but his one seems to do the job and give the right results.

SELECT tblProducts.ProductName AS [Product Name],
SUM(tblOrderDetails.Quantity) AS [Quantity Sold],
SUM(tblOrderDetails.Quantity * tblProducts.UnitPrice) As [Total Cost]
FROM tblOrders INNER JOIN tblOrderDetails ON tblOrders.OrderID = tblOrderDetails.OrderID
               INNER JOIN tblProducts ON tblOrderDetails.ProductID = tblProducts.ProductID
               INNER JOIN
               (SELECT tblOrders.OrderId as OrderId,
                sum(tblOrderDetails.Quantity * tblProducts.UnitPrice) as [COST]
                FROM tblOrders INNER JOIN tblOrderDetails on tblOrders.OrderID = tblOrderDetails.OrderId
                INNER JOIN tblProducts ON tblOrderDetails.ProductID = tblProducts.ProductID
                GROUP BY tblOrders.OrderID) as tblCost
                ON tblOrders.OrderID = tblCost.OrderId
                INNER JOIN
                (SELECT tblOrders.OrderID,
                 Sum(tblPayments.PaymentAmount) as [Paid]
                 FROM tblOrders INNER JOIN tblPayments ON tblOrders.OrderID = tblPayments.OrderID
                 Group BY tblOrders.OrderID ) as tblPaid
                 ON tblPaid.OrderID = tblOrders.OrderID
WHERE (tblOrders.OrderDate >= '2/25/2004') AND (tblOrders.OrderDate <= '2/29/2004')
       AND tblCost.Cost <= tblPaid.Paid
GROUP BY tblProducts.ProductName
