Some of you may be familiar with relational databases other than Teradata and how those other RDBMs utilize indexes. In Teradata, an âIndexâ is a physical mechanism that is used to distribute, store, and access data rows. Indexes provide a physical access path to the data and their use can avoid unnecessary full-table scans to locate rows.
CREATE TABLE with UNIQUE PRIMARY INDEX in Teradata. PRIMARY INDEX is mandatory for any table in Teradata. While creating a table in Teradata, Teradata will look for any primary index specified in the DDL. If the index is not specified, secondly it will look for Primary key constraint in DDL for making it primary index. If the above conditions are not met then Teradata will take the first column as a Primary index.
