A nonsequenced DELETE statement deletes the specified rows across all states. This ignores valid-time semantics when deleting rows from a table with valid time.

A nonsequenced delete operates on open rows only. A nonsequenced delete treats a valid-time column like a regular column.

For a bitemporal table, a nonsequenced delete of a row closes out the existing qualified row. For a valid-time table, the nonsequenced delete is like a conventional delete statement that physically deletes the qualified row.
