Description of the bug
The problem statement is not clear. It ask for the "id not equal to 2", but if we execute according to taking "id not equal to 2", then it says wrong solution.
But when one see the testcase, the testcase are running according to the "referee_id not equal to 2", tho later on we can consider NULL also.
But I request you to omit the problem statement rather than using
"Find the names of the customer that are not referred by the customer with id = 2. "
you should have used,
"Find the names of the customer that are not referred by the customer with referee_id = 2. "
Language used for code
MySQL
Code used for Submit/Run operation
"Select name from Customer where referee_id is NULL or not referee_id=2 ; "
// Paste your code here. Don't remove ``` given
// above and below the code.
Expected behavior
