The trim_expression argument must evaluate to a single byte that has a byte data type or single character that has a character data type.

TRIM operates on the following types of string_expression arguments:

  • Character, except for CLOB
  • Byte, except for BLOB
  • Numeric

    If a numeric expression is used as the string_expression argument, it is converted implicitly to CHARACTER type.

  • UDTs that have implicit casts to any of the following predefined types:
    • Character
    • Numeric
    • Byte
    • 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 TRIM, is a Teradata extension to the ANSI SQL standard.
