Solution 1

You need to use JOIN and GROUP BY.

It should look something like this:

SELECT what_you_need_to_select FROM Despatch AS d
INNER JOIN Processing AS p ON d.iid = p.iid
GROUP BY your_group

Try Following Query

Select Dest_From,Dest_To,Sum(weight),Sum(Amount) from Despatch and Processing where Despatch.iid=Processing.iid Group By(Dest_From,Dest_To,Sum(weight) as Sweight ,Sum(Amount) as Samount)
