A row that is no longer valid is a row in a valid-time or bitemporal table with a valid-time period that ends before the current time. It is considered to be a history row in the valid-time dimension.

For bitemporal tables, only rows that are open in the transaction-time dimension can be considered no longer valid. Rows that are closed in the transaction-time dimension of a bitemporal table are considered history rows, regardless of their valid-time period, and are not considered either valid or no longer valid.
