題目描述

X city opened a new cinema, many people would like to go to this cinema. The cinema also gives out a poster indicating the movies’ ratings and descriptions.

Please write a SQL query to output movies with an odd numbered ID and a description that is not ‘boring’. Order the result by rating.

For example, table cinema:

idmoviedescriptionrating

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

For the example above, the output should be:

idmoviedescriptionrating

5	House card	Interesting	9.1
1	War	great 3D	8.9

解題思路

SQL第三彈，說實話博主不怎么清楚SQL具體語句，去年學過的數據庫方面的知識忘得差不多了哈哈哈。所以不知道寫出來是否符合標準，不過確實是AC了，憑回憶寫的。這道題注意三個條件：
1. 選擇出來的id要為奇數； （id % 2 = 1）
2. description不能為boring； （description <> ‘boring’）
3. 選擇出來的數據按rating倒序排序。 （ORDER BY rating DESC）
具體見代碼。

實驗代碼

# Write your MySQL query statement below SELECT * FROM cinema WHERE (description <> 'boring') AND (id % 2 = 1) ORDER BY rating DESC
