The SOUNDEX Function
Syntax for the SOUNDEX function:
source-string is a character string expression.
Rules:
- The function returns a character string value containing six digits that represent an encoding of the sound of source-string.
- If source-string contains two or more words, they are effectively concatenated into a single word by ignoring the separating space characters.
- If the SOUNDEX values for two strings compare to be equal then they sound the same.
