To query a valid-time table such that no special temporal treatment is given to the valid-time column, use the NONSEQUENCED VALIDTIME temporal qualifier in the SELECT statement. For example:
NONSEQUENCED VALIDTIME SELECT * FROM Policy;
Result:
Policy_ID Customer_ID Policy_Type Policy_Details Policy_Term

The valid-time column, Policy_Term, is treated as a regular column with a period data type, and appears in the result set. All rows in the table are returned, even if they are history rows.
