Description
The DIFFERENCE() function returns an integer signifying the phonetic difference between two character strings. The DIFFERENCE() converts the specified character expressions, <expC1> and <expC2> into SOUNDEX codes and calculates the phonetic difference between the two. The DIFFERENCE() function returns an integer between 0 and 4. A return value of 4 represents a close match, and 0 is returned when the two character expression have no letters in common. The DIFFERENCE() function returns a 1 when the two expressions have one letter in common.
