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’.
