Sales By Qty Query Change

Question

Hello All --
Also for this Query would like to have option of selecting month at start of Query.  Then Query only shows the month selected when run.
Thanks!!
Mike
SELECT T0.ITEMCODE,

Hi Mike,
Try the following:
- Create a UDT called MonthList (or whatever you want).
- Populate the Code column with month numbers and the Name column with the month names e.g. Code = 1 and Name = Jan, Code = 2 and Name = Feb and so on.
- Then use the following query to get your item values per the month you select:
DECLARE @Mth AS VARCHAR(30), @MthNum AS SMALLINT
SELECT @MthNum = CAST(T0.Code AS SMALLINT) FROM [dbo].[@MonthList] T0 WHERE T0.Name = '[%0]'
SELECT @Mth = T1.Name FROM [dbo].[@MonthList] T1 WHERE CAST(T1.Code AS SMALLINT) = @MthNum
SELECT CASE WHEN (GROUPING(T0.ITEMCODE) = 1) THEN 'TOTAL QTY - ' + @Mth
ELSE T0.ITEMCODE END [ItemCode], SUM(T1.QUANTITY) AS 'Mthly Qty'
FROM dbo.OITM T0
LEFT JOIN dbo.INV1 T1 ON T1.ItemCode = T0.ItemCode
WHERE T0.SellItem = 'Y' AND MONTH(T1.DocDate) = @MthNum
GROUP BY T0.ItemCode WITH ROLLUP
I have added in an extra TOTAL row that displays the total quantity and the month name you selected.
The only issue with this is because the Name column in a UDT is alphanumeric, when you click the parameter selection button the months appear alphabetically e.g. Apr, Aug, Dec...
If you wanted you could get rid of the extra row and just display the selected month as an extra column. You can also populate the UDT with the full month names if you wish.
Just change the SUM(T1.Quantity) to SUM(T1.Quantity*T1.Price) and any descriptions from 'Qty' to 'Amt' etc for your other query.
Hope that helps.
Regards,
Andrew.
