To get a snapshot of a transaction-time table where the transaction-time period in the result rows overlap a specific time, use the TRANSACTIONTIME AS OF temporal qualifier in the SELECT statement. For example:
TRANSACTIONTIME AS OF DATE '2012-06-20' SELECT * FROM Policy_Types;
Result:
Policy_Name Policy_Type -------------------- ----------- Premium Automobile AP Basic Homeowner HM Business B Basic Automobile AU Premium Homeowner HP
Notice that the Major Medical policy type that was logically deleted from the table on 2012-06-19 does not appear in the result set, though it did appear in Example 5 when the NONSEQUENCED TRANSACTIONTIME qualifier to SELECT was used.
