Column storage attributes are a Teradata extension to ANSI SQL.

Not all data type attributes are supported for UDT, ARRAY, VARRAY, Geospatial, and Period column declarations, and no column storage or column constraint attributes are supported for those types.

You can specify server character sets for character data by specifying CHARACTER SET server_character_set for character columns.

The database supports the following server character sets.
  • LATIN
  • UNICODE
  • KANJISJIS
  • GRAPHIC

You cannot specify the server character set KANJI1.

The database automatically converts any existing character columns with a server character set of Kanji1 to a server character set of Unicode.
