How is the MySQL REPLACE() function used with the WHERE clause?

We know that the WHERE clause is used to add conditions in a MySQL query, and MySQL returns a result set based on these conditions. Similarly, when we use REPLACE() function with WHERE clause, the result set will depend on the conditions provided. The following is an example using data from the "Students" table, where the REPLACE() function replaces records in the "Name" column where the "Subject" column has the value "Computer".

Example

mysql> Select Name, REPLACE(Name, 'G','S') from student Where Subject = 'Computers';
+--------+------------------------+
| Name   | REPLACE(Name, 'G','S') |
+--------+------------------------+
| Gaurav | Saurav                 |
| Gaurav | Saurav                 |
+--------+------------------------+
