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 numeric data type such as FLOAT or INTEGER.

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 arithmetic operators, is a Teradata extension to the ANSI SQL standard. To disable this extension, set the DisableUDTImplCastForSysFuncOp field of the DBS Control Record to TRUE.
