[comp.databases] SOUNDEX

exnirad@brolga.cc.uq.oz.au (Nirad Sharma) (08/31/90)

I have been using the SOUNDEX function supplied with Oracle V5 and have
found it to be very convenient except that it may be too ambiguous. I
noticed that SOUNDEX only returns a 5 (or 4 - I forget) character string.
Is it possible that other soundex algorithms allow less ambiguity by making
use of more characters ? If so and if the source (pref. c) exists could
someone tell me how to get it, please ?

While I'm at it, are there any FTP sites holding various Oracle bits e.g.
forms, scripts and the like. ?

Thanks for any help

 This goes *way* back, about 30 years to when I did payroll work,
 but if I recall correctly, the Soundex algorithm (pre-computer,
 of course) we used then always produced the same small number of
 characters so that codes could be compared.  Varying length would
 defeat this purpose, and a longer fixed length would require
 progressively more useless padding of short codes for progressively
 more names as the fixed length increased.
