620. Not Boring Movies
SQL架构
Create table If Not Exists cinema (id int, movie varchar(255), description varchar(255), rating float(2, 1))
Truncate table cinema
insert into cinema (id, movie, description, rating) values ('1', 'War', 'great 3D', '8.9')
insert into cinema (id, movie, description, rating) values ('2', 'Science', 'fiction', '8.5')
insert into cinema (id, movie, description, rating) values ('3', 'irish', 'boring', '6.2')
insert into cinema (id, movie, description, rating) values ('4', 'Ice song', 'Fantacy', '8.6')
insert into cinema (id, movie, description, rating) values ('5', 'House card', 'Interesting', '9.1')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:
| 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 |
For the example above, the output should be:
| id | movie | description | rating |
|---|---|---|---|
| 5 | House card | Interesting | 9.1 |
| 1 | War | great 3D | 8.9 |
解题思路：
通过description和id进行筛选，然后通过rating进行倒序排序（DESC）
解答：
SELECT id, movie, description, rating
FROM cinema
WHERE id % 2 != 0 and description != 'boring'
ORDER BY rating DESC
