Flashback Query, Versions and Transactions

My flashback question pertains to recovering from a deleted row that was committed. To recover the row using flashback would I use flashback query embedded in an UPDATE statement? Or would I query FLASHBACK_TRANSACTION_QUERY to get the undo_sql then take the statement(s) and apply them to restore the row?
Matt

If the row was deleted you'd have to insert it.
ME_XE?delete temp;
100 rows deleted.
Elapsed: 00:00:00.04
ME_XE?insert into temp select * from temp as of timestamp sysdate-1 where col1 = 1;
1 row created.
Elapsed: 00:00:00.46
ME_XE?commit;
Commit complete.
Elapsed: 00:00:00.01
ME_XE?select * from temp;
COL1 SOME_DATE
1 22-JUL-2008 03 25:17
1 row selected.

Difference between Flashback Versions Query vs Flashback Transaction Query

plz somebody can clearly tell me difference between
--Flashback Versions Query
--Flashback Transaction Query

Hi,
I was able to test the data given by you
CREATE TABLE test1(a number);
INSERT INTO test1 values(1);
INSERT INTO test1 values(3);
COMMIT;
UPDATE test1 SET a=10 WHERE a=1;
COMMIT;
ALTEr TABLE test1 ENABLE ROW MOVEMENT;
INSERT INTO test1 values(1);
INSERT INTO test1 values(3);
COMMIT;
ALTEr TABLE test1 ENABLE ROW MOVEMENT;
SELECT * FROM test1 VERSIONS BETWEEN TIMESTAMP
TO_TIMESTAMP('2011-07-25 15:50:00', 'YYYY-MM-DD HH24:MI:SS') AND
TO_TIMESTAMP('2011-07-25 15:56:00', 'YYYY-MM-DD HH24:MI:SS');

Transfering Master and Transaction data to active and non active versions

Hi Gurus,
I am planning to transfer ECC master and transaction data to APO active and simulation versions.My question is
1. Is it possible to release Master and transaction data to active and non active versions ?
2. How i need to config if i want to release Master and Transaction data in version 001?
Please let me know .
Thanks in Advance
Regards,
Raj

Hi Raj,
1) Once you create active integration models for master data and
transactional data, the data will get updated in active version 000
2) For creation of non active version use transaction
/SAPAPO/MVM
3) For copying of data from active to non active version, use
transaction /SAPAPO/VERCOP

Doubt regarding flashback versions query

I am working with Oracle 10g database on Oracle Enterprise Linux
I was trying this query both as sysdba and connected as the respective user .
When connected as sysdba I was of course appending schema name to the table name while running the query so there were no errors.
SELECT VERSIONS_STARTTIME, VERSIONS_ENDTIME
      FROM emp_data
      VERSIONS BETWEEN TIMESTAMP MINVALUE AND MAXVALUE
      ORDER BY VERSIONS_STARTTIME ;
VERSIONS_STARTTIME                                VERSIONS_ENDTIME But unfortunately the query is returning null .
Let me know if any parameter has to be enabled for the query to work or what went wrong. The table of course has many transactions running and I was able to get the change through ora_rowscn but flashback versions query was the one not working.
Let me know if I have missed anything

Prabu,
If the transaction is still going on means they are not yet committed than Versions query won't show you anything.Also if you have surpassed the Undo_retention andhave most probably lost the required undo data,you wont be able to get any output from it.So check these two things.There are no special parameters required to use this feature except for automatic undo management and Undo retention.
In the meantime,you may also want to look at this link for a simple description of this and other flashback features,

Flashback Versions Query

Hi
Please explain me the advantages of Flashback Versions Query in 10g.I read 2 or more articles but still doubtful.It will be a great help if anybody clarify my doubt.
Thanx & cheers

verions of rows between two times and transaction that changed the rows
use this xid with flashback_transaction_query to get the undo_sql for revert the changes

Is there any difference between R/3 4.7 version and ECC 5.0 for the transaction RSA5.

Can any of you help me?

At what stage did you get this error?. Have you already selected the type of Flash Back Versions Query you want e.g Specifying type of Point in Time (Row Evaluation, Timestamp or SCN) or just when you select from the Action?

File and Transaction Parity in PI 7.1

Hello,
We are currently designing our file and transaction Parity architechture for SAP PI 7.1. Could you please let me know where can I start on it. Does PI offers any out of the box parity services and any kind on documentation on it.
Thank you.

The procedure is the same as it was in SAP PI7.0 or lower versions.....no major change on this front.
Search SDN for documents related to your protocol.

Flashback query works, but not flashback versions query

This is a test database (Oracle10g 10.1.0.5), not in archivelog mode. I deleted one row 2 hours ago. I can still use flashback query:
select * from tm_instances as of timestamp to_timestamp('STARTTIME_HERE') to view this row. But I can't use the following flashback versions query:
SELECT versions_startscn, versions_starttime,
versions_endscn, versions_endtime,
versions_xid, versions_operation from tm_instances VERSIONS BETWEEN TIMESTAMP to_timestamp('STARTTIME_HERE') and MAXVALUE
It gave the following error:
ORA-30052: invalid lower limit snapshot expression
So I guess flashback query works better than flashback versions query?
undo_retention is set to 900 by default here.
Thanks,
Hai

currently function returns all mydate rows, i just want mydesired date rowsCheck if there is a column in the table with the same name as the function parameter. It's the most probable reason of such DML operations behaviour in PL/SQL procedures and function.

Flashback query vs. flashback versions query

I have noticed that I can do a regular flashback query as far back as I have UNDO data available for the query, as long as long as the table definition has not changed. Flashback versions query, however, is limited to the UNDO retention parameter.
So, for example, if my UNDO_RETENTION parameter is set to the default 900 seconds, I can only go back 15 minutes in time, even if the regular flashback query shows data in the table from 1 hour ago.
Why does Oracle hold to the the retention parameter for versions query, but let you go back farther for the regular query?

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

How to ceate a new Country key,currency ,version and value type for report

hi,
can you please let me know How to ceate a new Country key,currency ,version and value type for report
along with tables and tcodes.
thanking you

Not clear on your comments
How to ceate a new Country key,currency,
version and value type for report
because in one line you are saying you want to create Country Key, which means your requirement is in some transaction whereas at the end, you say for report.
Can you let us know you want to develop a report and if so, from which transactions, you want to take datas. You have to be clear on this.
thanks

Read-only version of transaction FBL5N.

Hello Everybody,
I have to create a GOTO report from a query, where the jumping target should be the read-only version of transaction FBL5N.
Please let me know what is the read-only version of transaction FBL5N.
Thanks in advance
Shameem

Hi Siggi,
If I am right, I would be able to create the GOTO report, by specifying the jump target as the Transaction FBL5N.
And whenever the user uses the GOTO option, he would be able to only view the invoice details and not change anything.
Thanks,
Shameem

Flashback Versions Query vs Flashback Querya

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.
