Defining Teradata Table Indexes

The following properties are applicable to an Teradata Table Index object.

Tab	Property	Description	Additional Information
	Physical Name	Specifies the name of the index
	Type	Specifies the index type of the table
	Primary Index	Specifies whether the index is a primary index
	Primary AMP Index	Specifies whether the index is a primary AMP index	You cannot specify a Primary AMP Index on a Unique Index.
	GeoSpatial Index	Specifies whether the index is a GeoSpatial index	You cannot specify a GeoSpatial Index on a Unique Index.
	Is Unique	Specifies whether to allow only unique values in the table index
	Physical Only	Specifies whether the index appear in a physical model only
	Generate	Specifies whether a DDL statement is generated for the index during forward engineering
	Show FK Indexes	Specifies whether foreign key indexes appear in the index members list
General	Column	Specifies the columns that are included in the index
General	Sort Order	Specifies the order in which index values are stored	Ascending: Indicates that the index values are sorted in ascending order. Descending: Indicates that the index values are sorted in descending order. Random: Indicates that the index values are sorted in random order.
Options	Is Unnamed	Specifies whether to omit the object name during forward engineering
	Order By	Specifies how the rows are ordered on each AMP	Hash: Indicates that hash-ordering is applied for rows. This option limits the hash-ordering to one column, rather than the default ordering of all columns. Value: Indicates that value-ordering is applied for rows. This option optimizes queries that return a contiguous range of values, especially for a covering index or a nested join.
	With Load Identity	Specifies whether to record the RowLoadID for the index created on a load isolated table.	Yes: Indicates that RowLoadID of the index is recorded. No: Indicates that RowLoadID of the index is not recorded.
	Partition Expression	Specifies the expression for the partition
Ordering	Column	Specifies the available index member columns for sorting
