In this video, we will be looking at fictious house prices per region. However, the data is not for the same dates in each region.
How can you get the latest row for each group? So you need the latest row for East Midlands, the latest row for West Midlands etc.
There are at least three different ways for doing this:
1. In the WHERE clause, using a correlated query,
2. Using a JOIN, and
3. Using the ROW_NUMBER function.
Here is the code to create and populate the table. If you want to try it yourself, why not check your solutions with mine?

CREATE TABLE tblHouseprices (
PriceDate date NOT NULL,
Region varchar(20) NOT NULL,
price int NOT NULL);
GO
INSERT INTO tblHouseprices
VALUES
('2022-06-01', 'Greater Manchester', 346251),
('2022-07-01', 'East Midlands', 312289),
('2022-07-01', 'West Midlands', 365274),
('2022-08-01', 'East Midlands', 328072),
