A nonsequenced delete applies no special temporal logic to the delete operation or row selection, and operates on a valid-time table as a conventional delete would operate on a nontemporal table:
Start from the same valid-time table that was used for the sequenced delete examples:
Policy_ID Customer_ID Validity --------- ----------- ------------------------ 497201 304779902 ('05/02/14', '06/02/13') 540944 123344567 ('07/02/03', '08/02/02') 541077 766492008 ('09/12/21', '99/12/31') 541145 616035020 ('09/12/03', '10/12/01') 541008 246824626 ('09/10/01', '99/12/31')
Each of the following nonsequenced DELETE statements physically deletes one row from the table:
NONSEQUENCED VALIDTIME DELETE FROM Policy WHERE Customer_ID = 304779902; NONSEQUENCED VALIDTIME DELETE FROM Policy WHERE BEGIN(Validity) = DATE '2007-02-03';
