How to use Logical Operators In MySQL
Logical operators such as AND, OR, and NOT allow us to combine multiple conditions in a WHERE clause.
Example
Let’s Find students who are either younger than 20 years old or have a grade of ‘A’.
SELECT * FROM students WHERE age < 20 OR grade = 'A';
Output:
+----+---------+-----+-------+
| id | name | age | grade |
+----+---------+-----+-------+
| 1 | John | 20 | A |
| 3 | Michael | 21 | A |
| 4 | Sophia | 19 | C |
+----+---------+-----+-------+
