A UDT must have both an ordering and a transform defined for it before you can use it as the column data type of any table. Because ARRAY, VARRAY, Geospatial and Period data types are predefined as internal Teradata UDTs, their ordering and transforms are also predefined. If you attempt to create a table that contains a UDT column when that UDT does not yet have either an ordering or transform definition, the system returns an error to the requestor.

Not all the possible Vantage column attributes are valid when specified for a UDT column. For a list of the valid data type attributes for UDT, Geospatial, and Period columns, see Teradata Vantage™ - Data Types and Literals, B035-1143.
