The result data type and character set depend on those of the source_string argument.

  • If the source_string is CHAR, the result data type is VARCHAR.
  • If the source_string is VARCHAR, the result data type is VARCHAR.
  • If the source_string is CLOB, the result data type is CLOB.

For example, if the source_string argument has a data type of CHAR CHARACTER SET UNICODE, then the result data type will be VARCHAR CHARACTER SET UNICODE.

The maximum length of a VARCHAR result value is 16000 characters for LATIN, and 8000 characters for UNICODE.

An error is returned if the result string is larger than the maximum result string size.
