Teradata Database supports the creation of sequenced views to be used in Teradata Industry Logical Data Models (ILDMs). These views can use all existing Teradata Database features with a SEQUENCED qualifier. Some of the features that are often used in ILDMs are:

  • sequenced outer joins
  • sequenced subqueries (inclusion, exclusion joins)
  • sequenced aggregation
  • sequenced OLAP

Although these views are created using the SEQUENCED temporal qualifier, they can only be used in queries having point-in-time (CURRENT or AS OF) temporal qualifiers.
