Calculating amount from transactions...

Calculating amount from transactions...

Calculating amount from transactions...

Hi All,
Dont know if this is in the correct category but I'm trying to calculate amounts in sql.
This what I have:

One table with transactions. That's it basically. Every transaction represents an "deposit" or "withdrawal" of a product from a shelf. There's no data of the amount of products in the shelf and now I would like to calculate the amount of products in all shelfs during the day. Every day.

Transaction Datetime, Source, Destination, Product ID, Product Group
2019-02-01 08:01:00, Person1, Shelf1, 1234, 1
2019-02-01 10:01:00, Shelf1, Person1, 1234, 1
2019-02-01 08:03:00, Person2, Shelf1, 5678, 1

Desired table:
Hour, Date, Shelf, Product Group, Amount
8, 2019-02-01, Shelf1, 1, 5
9, 2019-02-01, Shelf1, 1, 10
10, 2019-02-01, Shelf1, 1, 10

Any ideas how to do this? Any suggestion would be appreciated

RE: Calculating amount from transactions...

that is a standard basic "group by" with a sum of the amount (or sum of 1 if no amount column available)

give it a try and come back with ddl for the table and your code attempts and issues if you need further help - and if you do get back do state sql vendor and version.
