How can we select records from a table if the absolute value of the difference between two values ​​is greater than a certain number?

If the absolute value of the difference between two values ​​is greater than a certain number, we can use the MySQL absolute value i.e. ABS() function to select records from the table. We demonstrate this using data from the "Marks" table.

Example

mysql> Select * from studentmarks where abs(Hindi-English)>10;
+--------+-------+---------+------+---------+-----------+
| Name   | Hindi | English | Math | Physics | Chemistry |
+--------+-------+---------+------+---------+-----------+
| Gaurav | 75    | 86      | 95   | 69      | 85        |
| Rahul  | 74    | 85      | 97   | 69      | 86        |
| Mohit  | 73    | 87      | 89   | 69      | 86        |
+--------+-------+---------+------+---------+-----------+
