MySQL's SOUNDEX(~) method returns a soundex string from the input string.
NOTE
A soundex string is usually a four character code to represent how a string sounds when spoken, however, SOUNDEX(~) method returns an arbitrarily long soundex string.
Parameters
1. str | string
The string to return soundex string for.
Return value
The soundex string for the input.
Examples
Basic usage
To return soundex string for 'see' and 'sea':
SELECT SOUNDEX('sea'), SOUNDEX('see');
+----------------+----------------+| SOUNDEX('sea') | SOUNDEX('see') |+----------------+----------------+| S000 | S000 |+----------------+----------------+
Both strings have the same soundex string, indicating they sound the same when spoken.
To return soundex string for 'listening' and 'listener':
SELECT SOUNDEX('listening'), SOUNDEX('listener');
+----------------------+---------------------+| SOUNDEX('listening') | SOUNDEX('listener') |+----------------------+---------------------+| L2352 | L2356 |+----------------------+---------------------+
Note that the end of the soundex string is different for the two input strings.
