How is Boolean logic used in database queries?

Can you explain how Boolean logic is applied in database queries?

Sure! Boolean logic uses operators like AND, OR, and NOT to filter data in database queries.

Can you give me an example of a query using these operators?

Of course! For instance, a query like SELECT * FROM users WHERE age > 18 AND city = 'New York' uses AND to filter users.

What about using OR? How does that work?

Using OR allows you to retrieve records that meet at least one of the conditions. For example, SELECT * FROM users WHERE city = 'New York' OR city = 'Los Angeles'.

And how does NOT work in a query?

NOT excludes records that meet a certain condition. For example, SELECT * FROM users WHERE NOT city = 'Chicago' retrieves users not in Chicago.
