Use CHAR2HEXINT on character strings or character string expressions.

By default, Teradata Database performs implicit type conversion on a UDT argument that has an implicit cast that casts between the UDT and a predefined character type.

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 CHAR2HEXINT, is a Teradata extension to the ANSI SQL standard.

CHAR2HEXINT is not supported for CLOBs.
