Like the phonetic alphabet that you might ha… You can rate examples to help us improve the quality of examples. To check the similarity between SOUNDEX codes of two strings, you use the DIFFERENCE() function. You might’ve noticed from the previous examples that the Soundex string starts with the first letter of the string. However, if the surname has a prefix, such as De, De la, Di, La, Le, Van, or Von, figure out the codes for the name both with and without the prefix -- it may be listed under either code. Example. The main purpose of the SOUNDEX () function is to compare the similarity between strings in terms of their sounds.

The goal is for names with the same pronunciation to be encoded to the same representation so that they can be matched despite minor differences in spelling. Die Funktion soundex gibt einen String aus 4 Zeichen, beginnend mit einem Buchstaben, zurück. You can then take that number and compare it to Soundex codes for other names that encode to that same number. The first character of the code is the first character of the expression, converted to upper case. Soundex is a phonetic algorithm for indexing names by sound, as pronounced in English. This article contains a bunch of Soundex examples to demonstrate how the SOUNDEX() function works in MySQL.
