Rising Temperature– LeetCode Problem
+---------------+---------+ | Column Name | Type | +---------------+---------+ | id | int | | recordDate | date | | temperature | int | +---------------+---------+ id is the primary key for this table. This table contains information about the temperature on a certain day.
Write an SQL query to find all dates’
Id with higher temperatures compared to its previous dates (yesterday).
Return the result table in any order.
The query result format is in the following example.
Input: Weather table: +----+------------+-------------+ | id | recordDate | temperature | +----+------------+-------------+ | 1 | 2015-01-01 | 10 | | 2 | 2015-01-02 | 25 | | 3 | 2015-01-03 | 20 | | 4 | 2015-01-04 | 30 | +----+------------+-------------+ Output: +----+ | id | +----+ | 2 | | 4 | +----+ Explanation: In 2015-01-02, the temperature was higher than the previous day (10 -> 25). In 2015-01-04, the temperature was higher than the previous day (20 -> 30).
Rising Temperature– LeetCode Solutions
Rising Temperature Solution in SQL:
First Problem solution.
select id from ( SELECT id, case when lag(Temperature) over(order by recordDate) < Temperature and lag(recordDate) over (order by RecordDate) = recordDate - interval '1' day THEN 1 ELSE 0 END SEL FROM weather )x where sel = 1
Second Problem solution.
SELECT Id FROM ( SELECT Id, (Temperature - LAG(Temperature) OVER (ORDER BY RecordDate)) as temp_diff, DATEDIFF(RecordDate, LAG(RecordDate) OVER (ORDER BY RecordDate)) as date_diff FROM Weather ) as innerQ WHERE temp_diff > 0 and date_diff = 1
Third Problem solution.
SELECT w.id FROM Weather w JOIN Weather p ON w.recordDate = DATE_ADD(p.recordDate, INTERVAL 1 DAY) AND w.Temperature > p.Temperature
