There is a factory website that has several machines each running the same number of processes. Write a solution to find the average time each machine takes to complete a process. The time to complete a process is the 'end' timestamp minus the 'start' timestamp. The average time is calculated by the total time to complete every process on the machine divided by the number of processes that were ..

Write a solution to find all dates' Id with higher temperatures compared to its previous dates (yesterday).Return the result table in any order.The result format is in the following example.SELECT w1.idFROM weather AS w1JOIN weather AS w2ON DATEDIFF(w1.recordDate, w2.recordDate) = 1 WHERE w1.temperature > w2.temperature① FROM weather AS w1 JOIN weather AS w2# 1개의 테이블을 JOIN 해준다. ② ON DATEDIFF(w1...
