Teradata Vantage™
By default, Vantage performs implicit type conversion on a UDT argument that has an implicit cast that casts between the UDT and any of the following predefined types:
  • Numeric
  • Character
  • DATE
  • Interval

To define an implicit cast for a UDT, use the CREATE CAST statement and specify the AS ASSIGNMENT clause. For more information on CREATE CAST, see Teradata Vantage™ - SQL Data Definition Language Syntax and Examples, B035-1144.

Implicit type conversion of UDTs for system operators and functions, including KURTOSIS, is a Teradata extension to the ANSI SQL standard. To disable this extension, set the DisableUDTImplCastForSysFuncOp field of the DBS Control Record to TRUE. For details, see Teradata Vantage™ - Database Utilities, B035-1102.

For more information on implicit type conversion of UDTs, see Teradata Vantage™ - Data Types and Literals, B035-1143 .
