Replace Function in MYSQL

In MySQL, the REPLACE function is used to replace all occurrences of a specified substring within a string with another substring. It's similar to the REPLACE function in Oracle and SQL Server.

Here's the syntax of the REPLACE function in MySQL:

REPLACE(original_string, old_substring, new_substring)

- original_string: The string in which to perform the replacement.

- old_substring: The substring to be replaced.

- new_substring: The substring to replace the occurrences of old_substring.

Example:

SELECT REPLACE('hello world', 'world', 'universe') AS replaced_string;

This will return 'hello universe', indicating that all occurrences of the substring 'world' have been replaced with 'universe' in the original string 'hello world'.
