题目:
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 |
+———+———–+————–+———–+
题意:查询cinema表中id为奇数且description不为boring的电影,并将结果按rating从大到小进行排序。
代码:
select * from cinemawhere mod(id,2)=1 and description != 'boring'order by rating desc
判断一个数是否为奇数的方法:
1.mod(id,2)=1
2.id%2<>1 或 id%2!=0
