VARGRAPHIC operates on the following types of arguments:

  • Character, except for CLOB
  • Numeric

    If the argument is numeric, it is implicitly converted to a character type.

  • UDTs that have implicit casts to any of the following predefined types:
    • Character
    • Numeric
    • DATE

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