力扣——上升的温度(数据库的题
给定一个 Weather
表,编写一个 SQL 查询,来查找与之前(昨天的)日期相比温度更高的所有日期的 Id。
+---------+------------------+------------------+ | Id(INT) | RecordDate(DATE) | Temperature(INT) | +---------+------------------+------------------+ | 1 | 2015-01-01 | 10 | | 2 | 2015-01-02 | 25 | | 3 | 2015-01-03 | 20 | | 4 | 2015-01-04 | 30 | +---------+------------------+------------------+
例如,根据上述给定的 Weather
表格,返回如下 Id:
+----+ | Id | +----+ | 2 | | 4 | +----+
# Write your MySQL query statement below select t.Id from Weather t,Weather y where t.RecordDate = DATE_ADD(y.RecordDate,INTERVAL 1 DAY ) and t.Temperature > y.Temperature
