Roll back deleted record in a trigger

Hi,
The question is How can i prevent a record that has a certain value from being deleted using a Before trigger?
i tryed
If :old.rowid=v then
roll back;
end if;
id does not work .
Any Help will be appreciated.

You can neer use a rollback in a trigger. You can just make a
check on your value and delete it only for those tou want.

HT4859 Is it possible to roll back your backup?

I unwittingly added my wife's new phone to my account which automatically added my contacts to her phone... she deleted mine and then added her own and now I have lost all of my contacts!!
I'm going to create a seprate one for her tonight but I just need to understand whether I will be able to get my old contacts back?

Hi Rajeev,
Please make sure you have the user in the WF and also under Roles Table you will see this:
Records
 Add records
 Modify records
 Modify checked out records
 Delete records
 Merge records
 Merge checked out records
 Protect records
 Unprotect records
 Check out records
 Check out new records
 Check in owned records
 Roll back owned records
 Check in non-owned records
 Roll back non-owned records
 Modify join permissions for non-owned records
select ROll back owned/non owned records also give your id Deletion permission for records.
Also put validation after each step with one branch-->True Rollback and false go ahead.
Let me know if you have any queries.
Thanks,
Ravi

How to call a trigger when a transaction is rolled back

Situation:
Using a trigger to propogate changes from an Oracle8 DB to a remote non-Oracle database ( it may not even be a rational database etc.). The trigger is connecting to a external procedure to send the change to the remote "database" - all updates are to be replicated - inserts, deletes etc.
Problem:
If an update transaction is aborted in the Oracle database, after the trigger has been called but before the transaction is committed. The transaction is rolled back successfully in the Oracle database, but nothing happens to the remote "database". Therefore there is now an data inconsistency !
How can I ensure that the transaction rollback occurs in the remote database as well ? There is no transaction monitor between the two databases. Can I get the trigger to be called again ?
Any ideas, suggestions ??
Many thanks in advance,
ismon

Hi;
You may use costum trigger which can be run after AP_CHECKS_ALL table has record

Data Services job rolling back Inserts but not Deletes or Updates

I have a fairly simple CDC job that I'm trying to put together. My source table has a record type code of "I" for Inserts, "D" for deletes, "UB" for Update Before and "UP" for Update After. I use a Map_CDC_Operation transform to update the destination table based on those codes.
I am not using the Transaction Control feature (because it just throws an error when I use it)
My issue is as follows.
Let's say I have a set of 10,000 Insert records in my source table. Record number 4000 happens to be a duplicate of record number 1. The job will process the records in order starting with record 1 and begin happily inserting records into the destination table. Once it gets to record 4000 however it runs into a duplicate key issue and then my try/catch block catches the error and the dataflow will exit. All records that were inserted prior to the error will be rolled back in the destination.
But the same is not true for updates or deletes. If I have 10000 deletes and 1 insert in the middle that happens to be an insert of a duplicate key, any deletes processed before the insert will not be rolled back. This is also the case for updates.
And again, I am not using Transaction Control, so I'm not sure why the Inserts are being rolled back, but more curiously Updates and Deletes are not being rolled back. I'm not sure why there isn't a consistent result regardless of type of operation. Does anyone know what's going on here or what I'm doing wrong/what my misconception may be?
Environment information: both source and destination are SQL Server 2008 databases and the Data Services version we use is 14.1.1.460.
If you require more information, please let me know.

Hi Michael,
Thanks for your reply. Here are all the options on my source table:
My Rows per commit on the table is 10,000.
Delete data table before loading is not checked.
Column comparison - Compare by name
Number of loaders - 1
Use overflow file - No
Use input keys - Yes
Update key columns - No
Auto correct load - No
Include in transaction - No
The rest were set to Not Applicable.
How can I see the size of the commits for each opcode? If they are in fact different from my Rows per commit (10,000) that may solve my issue.
I'm new to Data Services so I'm not sure how I would implement my own transaction control logic using a control column and script. Is there a guide somewhere I can follow?
I can also try using the Auto correct load feature. I'm guessing "upsert" was a typo for insert? Where is that option?
Thank you very much!

Roll back the updated records

One of our application users accidently updated approximately 1000 records of one of our Production Database tables .There are 3-5 records usually added /modifiled to this table per day .we also
restore a copy of our production database to Test server each night .In this situation, we wanted to roll back all transactions for that table those are updated by user accidently
so we decided to rename the production table and tried to copy table to production from the test database .Unfortunally
we could not rename the table name since there are a few production database tables are dependent on that table .Finally we compared the affected records of production table
with Test database table and created update script that updated all affected records with the original values .This recovery step was very time consuming especially during the business hours . when someone accidently delete ,update and modified
data , in this case what would be the possible options that SQL DBA can use to roll back the transactions without any downtime ?
Has someone used the ApexSQL log against the Production database to recover data before ?
Thank you in adavance for you help .
Daizy

Always prepared for a rollback steps (Scripts ), and make sure you have scheduled backups ( full and tlog )
If you know the exact time then you may try for point-in-time recvery using your full_tlod backup.. for this you should aware the exact time and again you have to do some manual work, because this is unplanned and human mistakes always risky and etc.., You
have to make sure that you are executing correct scripts and you may have to test the same in Test servers before executing.
Not sure how this ApexSQL works for rollback... you may have to test using your Test servers

HT4847 My camera roll back up on my iCloud is coming up at 5.2GB how do I clear up space, will it delete all photos on my iPhone?

My camera roll back up on my iCloud is coming up at 5.2 gb
If I turn off the back ups will it delete all photos on my iCloud?
Or delete all photos off my camera roll?

If you turn off your Camera Roll backup from your phone backup on iCloud, your Camera Roll photos won't be included in the next backup, getting 5.2 GB more of free space. Photo Stream has nothing to do with your phone backup, because your photos will still be there until 30 days after adding them, when Photo Stream deletes the photos automatically

OrionNetThat's a wrong advice to say that we can use Flashback to roll back a user drop operation. This is not possible with Flashback. Only with whole database being flashbacked ,it may be done but that's sort of like killing an ant with an missile. The simplest would be to get an export of the user's schema and import it to a newly created one.
The mentioned blog link also doesn't show the user rollback and the same is asked to the writer in the comment section.

I made an album just now. I went back to delete the pics from my camera roll but my only option is to "delete everywhere." I want to leave them in the new album I made.. How i can delete them from camera roll without deleting from other Album i made

I made an album just now. I went back to delete the pics from my camera roll but my only option is to "delete everywhere." I want to leave them in the new album I made.. How i can delete them from camera roll without deleting from other Album i made

The way that I understand that it works, is that the photos are not copied into the new albums, instead it just points to the photos - the number of photos on the iPad in Settings > General > About doesn't increase when you create new album so I assume from that that it isn't copying the photo, just pointing to it. So if you delete the photo from the camera roll you will therefore also be deleting all the pointers to it

Rolling back of Quick Pay Pre-payment and Quick Pay in case of void cheque

Hi All
I am facing an issue if you can help me out of if
Here is a scenario
a payroll manager runs the following processes.
1. Payroll run
2. Pre-Payments
3. Payroll Archiver
4. Payment Output file
After running all these process payroll manager finds that he also has to make an adhoc payment on account of car loan of AED 150,000.
So he runs following processes
1. Quick pay for Car loan
2. Quick pay pre-payments (payment made through check)
3. payroll archiver
4. Cheque Writer.
Now due to some technical fault, alignment on printing of cheque becomes disturbed there for cheque misprinted.
Payroll manager runs Void Cheque process to cancel the cheque.
After all these processes which has run successfully, order comes from upper management to rollback quickpay for adhoc payment of loan.
Now question is how it can be achieved.
I tried different things as follows
On Assignment Process results screen i queried the assignment which all the processes in descending order.
I tried to start roll back from cheque writer but system didn't allowed to do this because of check Void process.
I tried to start rollback from Magnetic report, system allowed to roll it back.
Then i tried to rollback Quick-pay prepayment, system did not allow me be do it. There fore i couldn't run rollback for Quick-pay.
There is an another thing i tried.
On "Assignment Process Result" screen i queried assignment. Then i delete the first entry of Void cheque by using delete option from menu bar on top and saved the record. then i delete cheque writer entry and saved the record. Then i run rollback for quick pay pre-payments and ran it successfully and then lastly i ran rollback for quick pay run.
One thing cautioned me that if I delete the void cheque entry then its history may be lost or have lost and on the other hand with out deleting void cheque i cannot proceed to rollback quick pay.
Kindly tell me the best way to run rollback for quick pay in this situation.
Regards
Majid

Bt do not provide broadband only so you need existing account holder to add broadband to phone account and then you can pay back the account holder - probably not what you want
the 12 months advance applies to the line rental not the broadband - as I said BT do not sell broadband only you buy a package which includes phone

MDB transaction getting silently rolled back?

          I have an MDB that is doing a delete of a database record in the onMessage method.
          It seems to work fine. I see no errors in the log, in fact I have some debug
          statements that indicate everything was completed normally. I even do a count
          sql using the same where clause and print the results and see a '0'.
          However, when I check the database, the record is still there.
          It seems as if the transaction is getting rolled back somehow. The MDB is transaction
          required/container tx. I never setRollbackOnly anywhere.
          The topic was originally published in a transaction that was rolled back, if that
          makes any difference. In fact, the point of the MDB is to clean up a record that
          was created during the transaction but not within the transaction.
          Any help is appreciated!
          ken


          It turned out that the MDB was using a different connection pool than it should
          have, which was pointed to an old copy of the database. So it wasn't really rolling
          back, it really was deleting records as desired, just in the wrong database.
          Thanks

How can I retrieve the condition in an update or delete using instead of trigger

I have 2 tables, on which a view is created. To distinguish the tables within the view trigger, a column "source" had been added in the view creation. I want to be able to delete row(s) in table t1 or table t2 through the view, depending on a condition. The problem is that I don't know how I can get back the delete condition IN the INSTEAD of trigger :
CREATE TABLE t1(m NUMBER, n VARCHAR2(10), o date);
CREATE TABLE t2(a NUMBER, b VARCHAR2(10), c date);
-- The view is created based on the 2 tables.
CREATE OR REPLACE VIEW vt12 AS
SELECT 't1' source, m, n, o
FROM t1
UNION
SELECT 't2' source, a, b, c
FROM t2;
-- The trigger will fire whenever INSERT is performed on the tables through the view
create or replace trigger tvt12 instead of insert or delete on vt12
begin
if inserting then
if :new.source = 't1' then
insert into t1 values (:new.m, :new.n, :new.o);
else
-- will insert a default value of -1 for the fourth column "d"
insert into t2(a,b,c,d) values (:new.m, :new.n, :new.o, -1);
end if;
elsif deleting then
-- We don't know the condition for the deletion, so all rows from the
-- table from which the current row is coming will be deleted
if :old.source = 't1' then
delete t1;
else
delete t2;
end if;
end if;
end;
show error
insert into vt12 values ('t1',1,'1',sysdate);
insert into vt12 values ('t2',2,'2',sysdate+1);
insert into vt12 values ('t1',3,'3',sysdate+2);
insert into vt12 values ('t2',4,'4',sysdate+3);
insert into vt12 values ('t1',5,'5',sysdate+4);
insert into vt12 values ('t2',6,'6',sysdate+5);
commit;
select * from vt12;
select * from t1;
select * from t2;
delete vt12 where m = 1;
commit;
select * from vt12;
select * from t1;
select * from t2;
When I execute this script, the delete statement seems to recognize that the condition is affecting a row in table t1, and therefore deletes all rows from the table, as specified in the delete statement of the trigger... But, what I want to do is ONLY to delete the row affected by the original condition. So my question is to know how I can get back the original condition for the delete, and still use it in the trigger, that will be executed INSTEAD of the delete statement.. I checked in the doc, and everywhere an example of INSTEAD OF trigger can be found, but it's always and only using an INSTEAD OF INSERT trigger, which doesn't need a condition.
Can anyone help ?
null

I've never faced this case myself, but from the documentation it would seem that the INSTEAD OF DELETE is also a FOR EACH ROW trigger. Therefore, you don't really have to worry about the actual "where" clause of the original "delete" operation: Oracle has it all parsed for you, so you just need to redirect, in turn, each view record being deleted to the appropriate table.
In extenso: for your
delete vt12 where m = 1;
=> the INSTEAD OF trigger fires once for all records in vt12 where m=1, and I would guess that you trigger code should look like:
begin
delete from t1 where m = :old.m and n = :old.n and o = :old.o;
delete from t2 where a = :old.m and b = :old.n and c = :old.o;
end;
It's a bit of overkill compared to the "where" clause of the original "delete" statement, but it should do the job...
BTW, if by any luck you do have some primary key on tables t1 and t2 (say: columns o and c respectively), then obviously you can make the thing simpler:
begin
delete from t1 where o = :old.o;
delete from t2 where c = :old.o;
end;

Regarding roll back and reassign the value.

hi all,
i am using forms6i.
Re: how to avoid the form's message situation
as we discussed my process has to happen like this. since it is a new topic so i have raised new thread.
what i want to do is based on the input values(base table values) i have to call one procedure, the procedure returned value i have to assign to one of my database field and one new record should go into other table.
so what i am doing is at the key-commit trigger i have written a procedure inside that i am calling a procedure which results in one value which i have to assigned to my blocks item. and one record to the table
my code in key commit trigger is something like
go_block('block name');
first_record;
based on the forms parameter call procedure
if procedure returns error then rollback otherwise assign value to base table item and one record to other table so
job_proc();
:block.item:= output ;
insert into job_table() values();
if system.last_record = 'TRUE' then
exit
else
next_record;
end loop;now senario is like if i am in fifth record four record processed as i explained before. in fifth record if i am getting error means
all four records value and insert statement should be reassined and rolled back.
so i have written like
exception when others then
forms_ddl('rollback');
go_block(block name);
go_record(system.current_record);
:block.item := null;
if :system.trigger_record = 1 then
exit;
else
previous_record;
end if;
end loop;is this is the way to rollback or is there any better way?
please advise.
Thanks..

Bean-managed stateless session bean can't roll back using JTA

I use weblogic6.1sp2 + jdk131
a stateless session bean must do 2 things:
insert a record to A table and delete another record in A table
this bean has the same structure as the example in
j2eetutorial/examples/src/ejb/teller
I use TxDataSource in weblogic
if delete fail, the roll back is run,but in database,
the insert record is STILL in A table.
any idea?

make sure that your deployment descriptor says "transaction required".
Also, If the insert and delete are two different methods, the client must call these two methods in the same transaction scope.

How can I roll back to an earlier version of OS 7 software
