+---------+------------+------------------+ | Id(INT) | Date(DATE) | Temperature(INT) | +---------+------------+------------------+ | 1 | 2015-01-01 | 10 | | 2 | 2015-01-02 | 25 | | 3 | 2015-01-03 | 20 | | 4 | 2015-01-04 | 30 | +---------+------------+------------------+

+----+ | Id | +----+ | 2 | | 4 | +----+
1 # Write your MySQL query statement below 2 select w1.Id 3 from Weather w1,Weather w2 4 where datediff(w1.Date,w2.Date)=1 5 and w1.Temperature>w2.Temperature;
