Table Kinds and UDT, Period, and Geospatial Data Types
The following table kind specifications all support UDT, ARRAY, VARRAY, Geospatial, and Period columns. Geospatial and Period data types are implemented internally as UDTs.
Global temporary trace tables do not support UDT columns. See “CREATE GLOBAL TEMPORARY TRACE TABLE” on page 317.
See “CREATE TABLE” in SQL Data Definition Language Syntax and Examples for information about the syntax used to specify table kinds.
You cannot use ALTER TABLE requests to change the table kind of a table.
