Full Join and sum 2 queries in access - sql

Question

I am very new to this type of complicated joins and summing functions.
I had 2 table queries which have same fields (i.e: ProdID, ProdName, NetQty, Unit)
The 1st one query contains OpStock and the 2nd one contains Purchase.
I want to add this 2 table query to make a single table so that I can able to see current stock.
The data looks like this for 1 st table is:
ProdID ProdName Qty
100 Rose 700
101 Lilly 550
103 Jasmine 600
105 Lavender 400
The data looks like this for 2nd table is:
ProdID ProdName Qty
100 Rose 400
101 Lilly 250
104 Lotus 1000
106 MariGold 400
The final data looks like this for 3rd table is:
ProdID ProdName Qty
100 Rose 1100
101 Lilly 800
103 Jasmine 600
104 Lotus 1000
105 Lavender 400
106 MariGold 400
How can i achieve this one using sql for access2003.
Thanks.
I am very sorry Ciaran,
This is purely access used for vb.net
Here Is my access query1
SELECT sp_OpenIandP_Prod.ProdID,
sp_OpenIandP_Prod.ProdName,
Sum(([sp_OpenIandP_Prod.SumOfNetQty]-[sp_OpenSales_Prod.SumOfNetQty])) AS NetQty,
sp_OpenIandP_Prod.UnitSName
FROM sp_OpenIandP_Prod
INNER JOIN sp_OpenSales_Prod ON sp_OpenIandP_Prod.ProdID=sp_OpenSales_Prod.ProdID
GROUP BY sp_OpenIandP_Prod.ProdID,
sp_OpenIandP_Prod.ProdName,
sp_OpenIandP_Prod.UnitSName;
The 1st query result would be like this:
ProdID ProdName NetQty UnitSName
1 Rose 0 Kgs
2 Lilly 7125 Mts
3 Lotus 12374 Nos
The second query is:
SELECT Products.ProdID, Products.ProdName,
Sum(OPDDetails.NetQty) AS SumOfNetQty, Units.UnitSName
FROM Units
INNER JOIN (Products
INNER JOIN (Brands
INNER JOIN OPDDetails ON Brands.BrID=OPDDetails.BrandID)
ON Products.ProdID=Brands.ProdID)
ON Units.UnitID=Products.UnitID
WHERE (((OPDDetails.PurID)>0)
AND ((OPDDetails.OPDDate)>=[StartDate] And (OPDDetails.OPDDate)<=[EndDate]))
GROUP BY Products.ProdID, Products.ProdName, Units.UnitSName;
and the result set would be like this:
ProdID ProdName SumOfNetQty UnitSName
1 Rose 1800 Kgs
2 Lilly 21000 Mts
I got the above result easily.
But it is not as much easy to get like this:
ProdID ProdName SumOfNetQty UnitSName
1 Rose 1800 Kgs
2 Lilly 28125 Mts
3 Lotus 12374 Nos
That's all. Thanks again.

Answer 1

This is not a vb.net question, however you need to use a UNION
Select ProdId, ProdName, Sum(Qty) As QtySum
From (Select ProdId, ProdName, Qty From TableA
Union All
Select ProdId, ProdName, Qty From TableB) DerrivedView
Group By ProdId, ProdName

Answer 2

You can create a UNION between your 2 queries then group by product:
SELECT ProdID, ProdName, Sum(NetQty) As NetQty, UnitSName
FROM
(
SELECT sp_OpenIandP_Prod.ProdID,
sp_OpenIandP_Prod.ProdName,
Sum(([sp_OpenIandP_Prod.SumOfNetQty]-[sp_OpenSales_Prod.SumOfNetQty])) AS NetQty,
sp_OpenIandP_Prod.UnitSName
FROM sp_OpenIandP_Prod
INNER JOIN sp_OpenSales_Prod ON sp_OpenIandP_Prod.ProdID=sp_OpenSales_Prod.ProdID
GROUP BY sp_OpenIandP_Prod.ProdID,
sp_OpenIandP_Prod.ProdName,
sp_OpenIandP_Prod.UnitSName
UNION ALL
SELECT Products.ProdID, Products.ProdName,
Sum(OPDDetails.NetQty) AS NetQty, Units.UnitSName
FROM Units
INNER JOIN (Products
INNER JOIN (Brands
INNER JOIN OPDDetails ON Brands.BrID=OPDDetails.BrandID)
ON Products.ProdID=Brands.ProdID)
ON Units.UnitID=Products.UnitID
WHERE (((OPDDetails.PurID)>0)
AND ((OPDDetails.OPDDate)>=[StartDate] And (OPDDetails.OPDDate)<=[EndDate]))
GROUP BY Products.ProdID, Products.ProdName, Units.UnitSName
)
GROUP BY ProdID, ProdName, UnitSName
