People will assume you've never been through anything because you don't carry a victim mindset, and your trauma isn't your personality

NULL means unknown / missing.
SQL’s rule is: you can’t compare something to NULL using = or !=.
salary = NULL;
This query basically returns zero rows.

While the latter will properly return all rows where salary is NULL.

[SumitM @SumitM_X]

SELECT * FROM users WHERE salary = NULL;

SELECT * FROM users WHERE salary IS NULL;

Are both these queries same?

It’s one thing to learn SQL and getting questions to practice your skill may be the challenge.

This is a long thread of websites to find SQL practice question across various topics.
