To query a valid-time table for the rows that are valid at the current time (rows that overlap with current time), use the CURRENT VALIDTIME temporal qualifier in the SELECT statement. For example:

   CURRENT VALIDTIME
   SELECT *
   FROM Policy
   WHERE Policy_Type = 'AU';

The result is a nontemporal result set. (The result set does not include the valid-time column.)

   Policy_ID  Customer_ID  Policy_Type  Policy_Details

      541077    766492008  AU           STD-CH-344-YXY-00
