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.
Therefore, the primary keys that are chosen must follow the rules for creating unique indexes. If a PRIMARY KEY constraint is defined on more than one column, values may be duplicated within one column, but each combination of values from all the columns in the PRIMARY KEY constraint definition must be unique.
