What is Soundex used for?
Soundex is a phonetic algorithm for indexing names by sound, as pronounced in English. The goal is for homophones to be encoded to the same representation so that they can be matched despite minor differences in spelling.
What is the use of Soundex () in SQL?
SOUNDEX converts an alphanumeric string to a four-character code that is based on how the string sounds when spoken in English. The first character of the code is the first character of character_expression, converted to upper case.
What is use of Soundex explain with an example?
The soundex() function calculates the soundex key of a string. A soundex key is a four character long alphanumeric string that represent English pronunciation of a word. The soundex() function can be used for spelling applications. Note: The soundex() function creates the same key for similar sounding words.
What is Soundex in MySQL?
SOUNDEX() function in MySQL is used to return a phonetic representation of a string. The phonetic represents the way the string will sound. The SOUNDEX function helps to compare words that are spelled differently, but sound alike in English.

How do you do a difference in SQL?
DIFFERENCE compares two different SOUNDEX values, and returns an integer value. This value measures the degree that the SOUNDEX values match, on a scale of 0 to 4. A value of 0 indicates weak or no similarity between the SOUNDEX values; 4 indicates strongly similar, or even identically matching, SOUNDEX values.
What is a SOUNDEX index?
The Soundex is a coded surname index (using the first letter of the last name and three digits) based on the way a name sounds rather than the way it’s spelled. Surnames that sound the same but are spelled differently – such as Smith and Smyth – have the same code and are filed together.
