197. Rising Temperature

Given a Weather table, write a SQL query to find all dates‘ Ids with higher temperature compared to its previous (yesterday‘s) dates.

+---------+------------+------------------+
| 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 |
+---------+------------+------------------+

For example, return the following Ids for the above Weather table:

+----+
| Id |
+----+
|  2 |
|  4 |
+----+

查找与昨天的日期相比更高的日期的id。

MySQL(1868ms):

SELECT w1.Id
FROM Weather w1 , Weather w2
WHERE w1.Temperature > w2.Temperature
  AND TO_DAYS(w1.Date) - TO_DAYS(w2.Date) = 1 ;
