MS SQL Server and Oracle and some major word editors. The soundex() function calculates the soundex key of a string. SQL> SQL> SQL> The big advantage of SOUNDEX is that it tokenizes the string. The other reason is that metaphone and dmetaphone take up a bit more space and are also more processor intensive to compute than soundex. It will also provide an overview of the RANK and DENSE_RANK functionality to complement the exploration of NTILE. Here's an in-depth explanation of the algorithm. The main difference lies in the … SQL. You can use SUBSTRING() on the result to get a standard soundex string. … - Selection from Oracle PL/SQL Programming, Third Edition [Book] More details on UTL_Match can be found here in the Oracle documentation, Soundex.
