The data types of byte_expression are restricted to the following:

  • BYTE, VARBYTE and BLOB
  • UDT that has an implicit cast to a predefined byte type

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