Use TRANSLATE_CHK on character strings and character string expressions.
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 TRANSLATE_CHK, is a Teradata extension to the ANSI SQL standard. To disable this extension, set the DisableUDTImplCastForSysFuncOp field of the DBS Control Record to TRUE.
