SELECT id, temperature,
LAG(temperature) OVER (ORDER BY recordDate) AS previous_day_temp, recordDate,
LAG(recordDate) OVER (ORDER BY recordDate) AS previous_day_date
FROM Weather
) subquery
WHERE DATEDIFF(recordDate, previous_day_date) = 1 AND
temperature > previous_day_temp;

Hello Sir, I’ve a request. I’ve been watching your videos from a while. The way you explain a concept is wonderful. Could you please also make videos on data analysis projects, that are available on stratascratch. This would help me and many of learners. Even if you can make like 10 of those videos, that would give us a brief idea, how to approach a project. Thank you so much, Sir.
Hope you have an amazing year ahead.
