Dynamic temp tables

Question

I am taking off the post, since didnt solve my purpose
Quote from post: "
why do you need dynamic temp tables?
Why not put all in same table and add a column called City inside it to identify the city to which they belong?"

Answer 1

I'm not understanding why you'd need temp tables either? This just looks like queries to me:
DECLARE @sales TABLE (orderID INT IDENTITY, salesID INT, city VARCHAR(30), branchID INT, amount FLOAT)
INSERT INTO @sales (salesID, city, branchID, amount)
VALUES
(1, 'New York', 1, 10),(1, 'Buffalo', 1, 10),(1, 'Albany', 1, 10),(1, 'Providence', 2, 10),
(2, 'New York', 1, 100),(2, 'New York', 1, 50),(2, 'New York', 1, 75),(2, 'Columbus', 3, 10),
(3, 'Toronto', 4, 10),(3, 'Vancouver', 5, 10),(3, 'Saskatchatoon', 6, 10)
--stage 1
SELECT *
FROM @sales
--stage 2
SELECT salesID, city, sum(amount) AS amount
FROM @sales
GROUP BY salesID, city
--stage 3
SELECT city, SUM(amount) AS amount
FROM @sales
GROUP BY city
Perhaps if you provided example data, DDL, DML and an expected output it would help to clarify what you need.
