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 | +----+
之前交了几次都没加TO_DAYS函数，我错了，我不该懒得装MySQL。
select A.Id from Weather A where A.Temperature > (select B.Temperature from Weather B where TO_DAYS(A.Date) - 1 = TO_DAYS(B.Date))
