Unable to write the SQL query as per my required output - sql

Question

I have two tables in MS Access database (Table1, Table2) with same columns namely Id, PartNo, Nomenclature, Quantity and Wksp. Id is the primary key in them. Id can be same in both tables. Now I want to write a query to get the output as shown under required output. How can I achieve this?
Table1
+----+--------+--------------+----------+----------+
| Id | PartNo | Nomenclature | Quantity | Wksp |
+----+--------+--------------+----------+----------+
| 1 | Part1 | Nomenc1 | 2 | Wksp1 |
| 2 | Part2 | Nomenc2 | 4 | Wksp1 |
| 3 | Part3 | Nomenc3 | 6 | Wksp1 |
| 4 | Part4 | Nomenc4 | 8 | Wksp1 |
+----+--------+--------------+----------+----------+
Table2
+----+--------+--------------+----------+-------+
| Id | PartNo | Nomenclature | Quantity | Wksp |
+----+--------+--------------+----------+-------+
| 1 | Part1 | Nomenc1 | 1 | Wksp2 |
| 2 | Part2 | Nomenc2 | 3 | Wksp2 |
| 3 | Part3 | Nomenc3 | 5 | Wksp2 |
| 4 | Part11 | Nomenc11 | 7 | Wksp2 |
| 5 | Part7 | Nomenc7 | 9 | Wksp2 |
+----+--------+--------------+----------+-------+
Required Output
+----+--------+--------------+-------+-------+
| Id | PartNo | Nomenclature | Wksp1 | Wksp2 |
+----+--------+--------------+-------+-------+
| 1 | Part1 | Nomenc1 | 2 | 1 |
| 2 | Part2 | Nomenc2 | 4 | 3 |
| 3 | Part3 | Nomenc3 | 6 | 5 |
| 4 | Part11 | Nomenc11 | 0 | 7 |
| 5 | Part7 | Nomenc7 | 0 | 9 |
| 6 | Part4 | Nomenc4 | 8 | 0 |
+----+--------+--------------+-------+-------+

Answer 1

First create a query to collect the IDs:
SELECT Id
FROM Table1
UNION
SELECT Id
FROM Tabel2;
Save this as, say, TBboth.
Then use this as source:
SELECT
TBboth.Id,
Nz(Table1!PartNo, Table2!PartNo) AS PartNo,
Nz(Table1!Nomenclature, Table2!Nomenclature) As Nomenclature,
Sum(Nz(Table1!Quantity,0)) AS Wksp1,
Sum(Nz(Table2!Quantity,0)) AS Wksp2
FROM
(TBboth
LEFT JOIN
TB1 ON TBboth.Id = TB1.Id)
LEFT JOIN
TB2 ON TBboth.Id = TB2.Id
GROUP BY
TBboth.Id,
Nz(Table1!PartNo, Table2!PartNo),
Nz(Table1!Nomenclature, Table2!Nomenclature);

Answer 2

Try this:
select Id , PartNo , Nomenclature, ISNULL(Wksp1,0) Wksp1, ISNULL(Wksp2,0) Wksp2
from
(
select Id , PartNo , Nomenclature ,Wksp, sum(Quantity) 'count' from Table1
group by Id , PartNo , Nomenclature,Wksp
union all
select Id , PartNo , Nomenclature ,Wksp, sum(Quantity) 'count' from Table2
group by Id , PartNo , Nomenclature,Wksp
) src
pivot
(
sum(count)
for Wksp in ([Wksp1], [Wksp2])
) P;

Try with This Method if you are using MS SQL Server
DECLARE #T1 TABLE
(
Id INT,
Part VARCHAR(20),
Qty INT,
Wksp VARCHAR(20) DEFAULT('Wksp 1')
)
DECLARE #T2 TABLE
(
Id INT,
Part VARCHAR(20),
Qty INT,
Wksp VARCHAR(20) DEFAULT('Wksp 2')
)
INSERT INTO #T1
VALUES(1,'Part1',10,'Wksp 1'),(2,'Part2',15,'Wksp 1'),(3,'Part3',12,'Wksp 1')
INSERT INTO #T1
VALUES(1,'Part1',10,'Wksp 2'),(2,'Part2',15,'Wksp 2'),(4,'Part4',20,'Wksp 2')
SELECT
Id = coalesce(a.id,b.id),
Part = coalesce(a.Part,b.Part),
Qty = coalesce(a.Qty,b.Qty),
Wksp =coalesce(a.Wksp,b.Wksp)
FROM #T1 A
FULL JOIN #T2 b
on a.Id = b.Id
