Flashback Versions Query vs Flashback Querya

Question

Hi,
When I run the following Flashback Query, it shows that employee number 101 has salary of 17000 at "2009-11-07 11:30:00":
SQL> SELECT employee_id, department_id, salary FROM employees
AS OF TIMESTAMP
TO_TIMESTAMP ('2009-11-07 11:30:00 PM', 'YYYY-MM-DD HH:MI:SS AM')
WHERE employee_id=101;
EMPLOYEE_ID DEPARTMENT_ID     SALARY
        101            90      17000However, when I run the following Flashback Versions Query on the same row,
it doesn't show the row status when the salary was 1700.
SELECT
VERSIONS_STARTTIME AS START_TIME,
VERSIONS_ENDTIME AS END_TIME,
versions_operation AS OPERATION,
last_name,
salary
  FROM EMPLOYEES
  VERSIONS BETWEEN TIMESTAMP MINVALUE AND MAXVALUE
  WHERE employee_id = 101;
START_TIME            END_TIME              O LAST_NAME           SALARY
08-NOV-09 09.45.59 AM                       U Kochhar              19500
08-NOV-09 09.45.38 AM 08-NOV-09 09.45.59 AM U Kochhar              19000
                      08-NOV-09 09.45.38 AM   Kochhar              18000
Why the Flashback Versions Query doesn't display status of the rows retreived by the Flashback Query although both of them depend on the Undo?
Thanks in advance.

Answer 1

Flashback query shows 7th Nov value and the next query shows 8th nov value..
