Is there any error in the following MySQL command?

SELECT emp_id, title, start_date, fname, fed_id
FROM person
ORDER BY 2, 5;

Solution (By Examveda Team)

This question tests your understanding of how to use the ORDER BY clause in MySQL to sort data. The ORDER BY clause allows you to specify the columns you want to sort by and the order (ascending or descending).

In this code, you have:

SELECT emp_id, title, start_date, fname, fed_id
FROM person
ORDER BY 2, 5;

Here's what it means:

* SELECT emp_id, title, start_date, fname, fed_id: This selects the columns you want to retrieve from the "person" table.
* FROM person: This specifies the table to retrieve data from.
* ORDER BY 2, 5: This is where the sorting happens! The numbers "2" and "5" refer to the column positions in the SELECT statement:
* 2: This means the second column, which is "title" in this case.
* 5: This means the fifth column, which is "fed_id" in this case.

This command will sort the data in the following way:

1. First, it sorts by the "title" column. 2. Then, for any rows with the same "title," it sorts by the "fed_id" column.

So, is there any error in the code? The answer is Option B: No. This code is perfectly valid!
