Teradata Vantageā„¢

Use SOUNDEX on character strings or character string expressions that use the LATIN or UNICODE server character set.

SOUNDEX does not accept CLOB types.

By default, Vantage performs implicit type conversion on UDT arguments that have implicit casts to predefined character types.

To define an implicit cast for a UDT, use the CREATE CAST statement and specify the AS ASSIGNMENT clause.

Implicit type conversion of UDTs for system operators and functions, including SOUNDEX, is a Teradata extension to the ANSI SQL standard. To disable this extension, set the DisableUDTImplCastForSysFuncOp field of the DBS Control Record to TRUE.

If the string_expression argument is null, the result is null.
