To query a valid-time table for the rows that are valid at a specific time period, use the SEQUENCED VALIDTIME temporal qualifier in the SELECT statement. For example:
SEQUENCED VALIDTIME PERIOD '(2009-01-01, 2009-12-31)' SELECT Policy_ID, Customer_ID FROM Policy WHERE Policy_Type = 'AU';
The result set is a temporal table that includes rows that are valid for a period of applicability specified by PERIOD '(2009-01-01, 2009-12-31)':
Policy_ID Customer_ID VALIDTIME
--------- ----------- ------------------------
541077 766492008 ('09/12/21', '09/12/31')
541145 616035020 ('09/12/03', '09/12/31')
541008 246824626 ('09/10/01', '09/12/31')
The valid-time column for the result set, VALIDTIME, which is automatically appended to the results of a sequenced valid-time query, is different from the valid-time column (Policy_Term) of the temporal table that was queried. The valid time for the results of the query is the intersection of the PA of the query and the original valid-time periods of the rows.
