By default, Vantage performs implicit type conversion on UDT arguments that have implicit casts that cast between the UDTs 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 Vantageā„¢ - SQL Data Definition Language Syntax and Examples, B035-1144.

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