Explanation

ROWID (pseudo-column for row address), BFILE (external binary file locator), VARCHAR2 (variable-length string), and LONG RAW (legacy binary data) are all valid Oracle data types. SHORT RAW and POINTER are not valid Oracle data types - these are likely fabrications or confusion with other databases.
