mysql soundex

MySQL Soundex is a built-in function in MySQL that returns a phonetic representation of a given string. The Soundex algorithm converts words that are spelled differently but sound alike into the same code. This function is useful for searching for similar names or words that might have different spellings.

To use the MySQL Soundex function, you can simply call it with the string you want to convert as the argument, like this:

SELECT SOUNDEX('Hello');

The function will return a four-character code that represents the sound of the word "Hello". If you pass in a longer string, the function will only consider the first 255 characters. Note that the Soundex function is case-insensitive and only works with ASCII characters.
