Table: Cinema

+----------------+----------+
| Column Name    | Type     |
+----------------+----------+
| id             | int      |
| movie          | varchar  |
| description    | varchar  |
| rating         | float    |
+----------------+----------+
id is the primary key (column with unique values) for this table.
Each row contains information about the name of a movie, its genre, and its rating.
rating is a 2 decimal places float in the range [0, 10]
 

Write a solution to report the movies with an odd-numbered ID 
and a description that is not "boring".

Return the result table ordered by rating in descending order.

The result format is in the following example.

 

Example 1:

Input: 
Cinema table:
+----+------------+-------------+--------+
| 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    |
+----+------------+-------------+--------+
Output: 
+----+------------+-------------+--------+
| id | movie      | description | rating |
+----+------------+-------------+--------+
| 5  | House card | Interesting | 9.1    |
| 1  | War        | great 3D    | 8.9    |
+----+------------+-------------+--------+
Explanation: 
We have three movies with odd-numbered IDs: 1, 3, and 5. 
The movie with ID = 3 is boring so we do not include it in the answer.

WHERE 조건과 ORDER BY를 사용

  • 홀수 ID: id%2 =1
  • boring이 아닌 영화: description != 'boring'
  • rating 내림차순 정렬: ORDER BY rating DESC
