Counting Version 1 and 0

Question

I have a table with the following...
Date id version_num total
01/01/2009 09:00:00 101 0 99
01/01/2009 09:00:00 101 1 100
02/01/2009 09:00:00 101 1 201
03/01/2009 09:00:00 101 1 150
04/01/2009 09:00:00 101 1 99
05/01/2009 09:00:00 101 0 103
05/01/2009 09:00:00 101 1 104
01/01/2009 09:00:00 202 1 99
02/01/2009 09:00:00 202 0 98
02/01/2009 09:00:00 202 1 97
03/01/2009 09:00:00 202 0 200
04/01/2009 09:00:00 202 0 99
I want to show all of the rows with a version 1 and also a version 0 for the same date...
01/01/2009 09:00:00 101 0 99
01/01/2009 09:00:00 101 1 100
05/01/2009 09:00:00 101 0 103
05/01/2009 09:00:00 101 1 104
02/01/2009 09:00:00 202 0 98
02/01/2009 09:00:00 202 1 97
If a date only has a version 0 and no version 1 then it should be ignored.
I only want to show dates with BOTH version 1 and 0.

It always helps if you post your sample data using DDL/DML (Create/Insert) scripts so we can easily generate results. Also please post sample data and expected results in \ tags.
Here is a possible solution:SQL> WITH test_data AS
2 (
3 SELECT TO_DATE('01/01/2009 09:00:00','MM/DD/YYYY HH24:MI:SS') AS DT, 101 AS ID, 0 AS VERSION_NUM, 99 AS TOTAL FROM DUAL UNION ALL
4 SELECT TO_DATE('01/01/2009 09:00:00','MM/DD/YYYY HH24:MI:SS') AS DT, 101 AS ID, 1 AS VERSION_NUM, 100 AS TOTAL FROM DUAL UNION ALL
5 SELECT TO_DATE('02/01/2009 09:00:00','MM/DD/YYYY HH24:MI:SS') AS DT, 101 AS ID, 1 AS VERSION_NUM, 201 AS TOTAL FROM DUAL UNION ALL
6 SELECT TO_DATE('03/01/2009 09:00:00','MM/DD/YYYY HH24:MI:SS') AS DT, 101 AS ID, 1 AS VERSION_NUM, 150 AS TOTAL FROM DUAL UNION ALL
7 SELECT TO_DATE('04/01/2009 09:00:00','MM/DD/YYYY HH24:MI:SS') AS DT, 101 AS ID, 1 AS VERSION_NUM, 99 AS TOTAL FROM DUAL UNION ALL
8 SELECT TO_DATE('05/01/2009 09:00:00','MM/DD/YYYY HH24:MI:SS') AS DT, 101 AS ID, 0 AS VERSION_NUM, 103 AS TOTAL FROM DUAL UNION ALL
9 SELECT TO_DATE('05/01/2009 09:00:00','MM/DD/YYYY HH24:MI:SS') AS DT, 101 AS ID, 1 AS VERSION_NUM, 104 AS TOTAL FROM DUAL UNION ALL
