The LOCATE() function in MySQL is used to search for a substring within a given string and returns the position of the first occurrence of the substring. The syntax of this function is as follows:

LOCATE(substring, string, start)

In this case, substring represents the sub-string to be searched for, string represents the string in which the sub-string is to be searched, and start represents the position at which the search should begin, with a default value of 1.

For instance, to search for the substring “World” within the string “Hello, World!”, you can use the following SQL statement:

SELECT LOCATE('World', 'Hello, World!');

This statement will return a result of 7, indicating that the substring “World” appears in the string “Hello, World!” starting at the 7th position.
