Omkar Ghurye :
Here,in billtran table the productid=1 is repeated twice
I want to find the sum(billtran.quantity) of each productid separately
select Query1:
select name,billtran.quantity from product inner join billtran on product.id=billtran.productid where product.id in(select id from product)
Caius Jard :
Per comment:
select name, SUM(billtran.quantity) from product inner join billtran on product.id=billtran.productid where product.id in(select id from product)
GROUP BY NAME
My additions in caps
Note: where product.id in(select id from product) is an entirely useless where clause and should be removed. Queries don't have to have a where clause and don't need one that says a table id should be in all the ids in that table (always true)
I would hence have written this one as:
SELECT
p.name,
SUM(b.quantity) as sumof_quantity
FROM
product p
INNER JOIN billtran b ON p.id=b.productid
GROUP BY
p.name
