Purpose

Starting from the end of the input string, a substring is created with the number of characters specified by the second parameter.

The RIGHT function can be called with the 'RIGHT' or 'TD_RIGHT' alias names.

The arguments include two parameters:

  • First Parameter

    The input string that the substring will be created from. CHAR, VARCHAR, and CLOB are supported while other types must be explicitly casted. The input can be null or an empty string.

  • Second Parameter

    A positive integer specifying the number of characters desired from the right side of the string. If the number of character exceeds the number of characters in the original string, then the original string will be returned.
