Table: Data

+-------------+------+

| Column Name | Type |

+-------------+------+

| first_col   | int  |

| second_col  | int  |

+-------------+------+


There is no primary key for this table and it may contain duplicates.

 

Write an SQL query to independently:

order first_col in ascending order.

order second_col in descending order.

The query result format is in the following example.

 

Example 1:

Input:

Data table:

+-----------+------------+

| first_col | second_col |

+-----------+------------+

| 4         | 2          |

| 2         | 3          |

| 3         | 1          |

| 1         | 4          |

+-----------+------------+

Output:

+-----------+------------+

| first_col | second_col |

+-----------+------------+

| 1         | 4          |

| 2         | 3          |

| 3         | 2          |

| 4         | 1          |

+-----------+------------+

Create table Data (first_col int, second_col int)

Truncate table Data

insert into Data (first_col, second_col) values ('4', '2')

insert into Data (first_col, second_col) values ('2', '3')

insert into Data (first_col, second_col) values ('3', '1')

insert into Data (first_col, second_col) values ('1', '4')

;
