Leetcode No.620 有趣的电影

难度：简单

编写一个 SQL查询，找出所有影片描述为非 boring (不无聊) 的并且 id 为奇数的影片，结果请按等级 rating 排列。

例如，下表 cinema:

+---------+-----------+--------------+-----------+
|   id    | movie     |  description |  rating   |
+---------+-----------+--------------+-----------+
|   1     | War       |   great 3D   |   8.9     |
|   2     | Science   |   fiction    |   8.5     |
|   3     | irish     |   boring     |   6.2     |
|   4     | Ice song  |   Fantacy    |   8.6     |
|   5     | House card|   Interesting|   9.1     |
+---------+-----------+--------------+-----------+

对于上面的例子，则正确的输出是为：

+---------+-----------+--------------+-----------+
|   id    | movie     |  description |  rating   |
+---------+-----------+--------------+-----------+
|   5     | House card|   Interesting|   9.1     |
|   1     | War       |   great 3D   |   8.9     |
+---------+-----------+--------------+-----------+

解答：

select *
from cinema
where id%2<>0 and description<>'boring'
order by rating desc

官方题解里使用了mod(id, 2) = 1也可以
小tips：在sql语句中，不等于的表达尽量写为<>而不是!=
