Explanation:
The query is asking for the salary to be displayed in descending order (from highest to lowest) and the name of the employees to be sorted alphabetically.
Answer:
The correct option is (c) Desc, Asc.
Explanation:
The ORDER BY clause is used to sort the result set based on one or more columns. In this case, we are sorting the result set based on two columns: salary and name.
To sort the salary in descending order (from highest to lowest), we need to use the keyword DESC after the salary column in the ORDER BY clause. This will arrange the records in a descending order of their salary values.
To sort the name in ascending order (alphabetically), we need to use the keyword ASC after the name column in the ORDER BY clause. This will arrange the records in an ascending order of their name values.
Therefore, the correct syntax for the ORDER BY clause in this case is:
ORDER BY salary DESC, name ASC
This will display the records in the result set with the highest salary first, followed by the employees' names sorted alphabetically.
Example:
Let's consider a hypothetical table "instructor" with the following columns: id, name, salary.
If we execute the query with the correct syntax, the result set will be displayed as follows:
| id | name | salary |
|----|---------|--------|
| 1 | John | 5000 |
| 2 | Alice | 5000 |
| 3 | Bob | 4000 |
| 4 | Claire | 3000 |
| 5 | David | 3000 |
| 6 | Emily | 2000 |
| 7 | Frank | 2000 |
In this example, the salary column is sorted in descending order (from highest to lowest), and the name column is sorted in ascending order (alphabetically).
Therefore, option (c) Desc, Asc is the correct answer.
