How can REPLACE() be used with UPDATE clause to make permanent changes to a table?

As we know that REPLACE () function is used to replace the occurrences of a substring with another substring within a string. We can also use the REPLACE function with the UPDATE statement to update the table. Following example will demonstrate it −

Example

mysql> Update Student set Father_Name = REPLACE(Father_Name, 'Mr.','Shri ');
Query OK, 5 rows affected (0.06 sec)
Rows matched: 5 Changed: 5 Warnings: 0

mysql> Select Name, Father_Name from Student;
+---------+-----------------+
| Name    | Father_Name     |
+---------+-----------------+
| Gaurav  | Shri Ramesh     |
| Aarav   | Shri Sanjay     |
| Harshit | Shri Lovkesh    |
| Gaurav  | Shri Ramchander |
| Yashraj | Shri Mohan      |
+---------+-----------------+
5 rows in set (0.00 sec)

The above query has updated the column Father_name by finding ‘Mr.’ and replacing the same with ‘Shri’.
