fetch the BONE inside an INSERT/UPDATE trigger USER?
HI guyz,I'm checking a table based on inserts and updates on this topic, I write the following trigger
CREATE TABLE emp_audit)

new_sal NUMBER (7.2).
new_comm NUMBER (7.2).
new_deptno NUMBER (2),
changed_by VARCHAR2 (8).
change_type char (1),
timestamp DATE);
CREATE OR REPLACE TRIGGER LogEmpChanges
Before you INSERT or REMOVE or UPDATE ON scott.emp
FOR EACH LINE
DECLARE
v_ChangeType char (1);

emp_audit. SYSDATE can generate the timestamp, and
USER to return the current user's user ID. */
INSERT INTO emp_audit
(change_type, changed_by, timestamp, old_empno,
old_ename, old_job, old_mgr, old_hiredate, old_sal,
old_comm, old_deptno, new_empno, new_ename, new_job,

END LogEmpChanges;

I need to get the user to the BONE, like going looking for 'USER' will not help because there is that one user of the application that connects to the database, we can trap the user with the 'OSUSER"that displays in the view ' V$ SESSION.
Please give some suggestions...

After that insert update trigger does not work properly
Hello experts!
I created an insert/update trigger after and what strikes me is that it does not work as expected.
The trigger starts a procedure that performs an insert in a second case of changing values table triggered table ("my_table").
The problem is that in my second table values, which are correlated to the "my_table", are not changed by the correct values immediately. The trails of the trigger and insert!
I need to update two times to values appear in my second table. Then only the data of the first update will be inserted in the second recital to table the table parent ("my_table") held the most recent values.
Do you have an idea what could be the problem?
Brgds,create or replace trigger myscheme.after_update_insert_set_tw after update or insert on myscheme.my_table for each row declare begin pr_my_table_tw_sync_sk(:new.lng_falle, :new.int_fallennummer, :new.lng_schaedling, :new.objectid); end;
SEBRemove the pragma autonomous_transaction and validation of your relaxation. This might be the reason. The transaction autonoumous cant properly consider the values of the current transaction (which is not engaged yet).
This is not logically (if the upgrade fails or is rolled at the time you do not want the inserted row).
If you then get a problem because the mutation of tables, you will need a different solution: an autonoumous transaction is not the right solution to workaround.

What is the best way to store the RCS for an insert/update in this rec
Oracle on Win 64 non-conteneur 12.1.0.2
When a record in one table is inserted or updated, what would be the best way to store the RCS for this record in this folder.
I thought of a line after trigger, but did not know if this trigger to store the current_scn would still fire that trigger again (recursive trigger).
Someone at - he a good idea of what the best way is to do? The devs don't want to store the pk and the SNA in yet another table...
Yes, row_dependencies would be the best way to go. But mgmt doesn't recreate all tables for this.
3rd party applications retrieve data from tables (all data). We are looking for a way for them to just pull what is new or updated updated since their last sweater.
I suggest that you try again and give all OF THE REQUIREMENTS.
You have rejected ANY answer given and he justified using 'hidden' on what knowledge management or the devs want or do not want to. Stop making us guess what are the requirements and constraints. If you want a real answer then tell us ALL the news.
When a record in one table is inserted or updated, what would be the best way to store the RCS for this record in this folder.
Solomon answered repeatedly. If you want to add a column to a table to store the then "best" SNA is to let the Oracle to do this for you automatically by using the DEPENDENCY LINE.
As he says also re-create the table to add this clause will be MUCH MORE EFFECTIVE that everything THAT you can do it manually. It will be also more accurate because Oracle will fill the value ORA_ROWSCN with the SNA at the time the line was committed. You, as long as user, can't fill a column in function when a line is engaged since real VALIDATION belongs to a transaction, not the line or the trigger that you use.
Yes - there are two drawbacks to this method:
1. you need to re-create the table
2. you cannot add an index to this "hidden" column
The devs don't want to store the pk and the SNA in yet another table...
Then? Who cares what the devs want to do? You want the BEST solution? Next, you will need to put aside personal preferences and determine what is the 'best' solution. Why it is important that certain dev wants to do this or not?
OK, the problem of biz is now, 3rd party external users are an all-wheel drive large number of tables in the database via the API that we wrote. That was obviously interrupted OLTP during the day. To reduce to the minimum, we want for them just to extract data that has been inserted/updated since their last sweater.
It is the definition of a "replica" DB Then why don't you consider a real replicated DB? You can use DataGuard and have replicated DB which is read only that can be used to generate reports. Oracle does ALL the work to keep ALL the tables in sync. You and your developers do NOTHING!
We thought that store the RCS higher their last sweater would allow the API to extract only data with YVERT higher than their last data pull CHN.
OK - except you keep rejecting solutions actually do. Ask you questions about the SNA stored in the same table, but then reject the solution that does this. And then you add your "devs" don't want to store the info in a new table either.
Then your solutions must ONLY use the replication or Log Miner. The REDO logs have all changes, if you want to extract yourself. Replication (e.g., DataGuard) will use these logs for you to maintain a replicated database.
We thought about it, but recreate all tables in production with ROWDEPENDENCIES as well as dealing with CF and other dependencies idea this was shot.
Well you NEVER mentioned you "thought that" and rejected it. And you NEVER mentioned anything about FKs and other dependencies. What is FKs and other dependencies which prevents this working solution? Tell us! Give us ALL the information.
Wouldn't a trigger AFTER LINE capture the commit YVERT? Or is after really not after validation?
No - a trigger has NOT one commit. A trigger runs as a step in a transaction. Validation applies to the entire transaction. Until you, or Oracle, issues a commit, there is NO "committed SNA" to be stored as ORA_ROWSCN.
You can easily see that for yourself. Create a simple table with dependencies of the line and then update two different sessions.
create the table emp_scn rowdependencies in select * from emp where rownum<>
Select empno, emp_scn ora_rowscn
Update emp_scn set work = 'b' where empno = 7499
commit;
The first SELECT statement will show you that each row has the same SNA.
EMPNO, ORA_ROWSCN
7369,70622201
7499,70622201
7521,70622201
Now, do the update (but no commit), then SELECT it
EMPNO, ORA_ROWSCN
7369,70622201
7499,
7521,70622201
Where is the value of 7499? This session will NOT see a value for the changed lines in the current transaction. Other sessions will still see the old value.
Now do the validation, then SELECT
EMPNO, ORA_ROWSCN
7369,70622201
7499,70622301
7521,70622201
7499 now has a new and different value than the other lines. It will not be this new value until the validation occurs.
Yes, row_dependencies would be the best way to go. But mgmt doesn't recreate all tables for this.
Well, you got the answer you want. You ask the best way. Now, you say that you were told the best way. But now you don't like the answer.
How is it our fault? Your question has been answered wasn't she?
Here are the facts:
1 oracle creates a history of changes - the REDO log files
2. you can use Log Miner to extract these changes
3. you can create your own change log by adding a log file of MV to your table.
4. you can then write a custom code to use this MV log file to determine which rows to "reproduce".
So far reject you all THE POSSIBLE solutions.
Accept it or change the requirements to allow one of the solutions proposed to be used.
Personally, if I HAD to use a customized solution, I would use a MV journal to record the ROWID of the lines that have changed (for tables ROWID cannot be changed). I would then extract the appropriate lines by pulling on the lines corresponding to these row ID.
Even that has problems since a line can be changed several times and children lines can also be amended several times - these questions FK you mentioned.
I suggest you read this entire thread on AskTom a dozen years ago. It addresses ALL these issues.

trigger check the previous record of line before insert/update
Hi all
I would like to create a trigger that a customer will not be able to create a new account, if it has a status of "Non-payment".
CustomerID custNRIC paymentStatus
----------------------------------------------------------------
Non-payment of 200 F7654323A
It will reject the following statement.
insert into customer (custID, custNRIC, paymentStatus) VALUES (201, 'F7654323A', 'Good');
so, how can I go around to solve this issue?
sqlnoob wrote:

You can't do things like that in a trigger.
It will reject the following statement.
insert into customer (custID, custNRIC, paymentStatus) VALUES (201, 'F7654323A', 'Good');
The trigger would dismiss as EVERY other row in the same transaction, if you try to use a trigger.
You can't stop a trigger to run except by raising an exception and the trigger stop from doing anything for ANY line that the trigger activated on.
together to define
CREATE OR REPLACE TRIGGER reject_new_account
AFTER INSERT OR update ON the client
FOR EACH LINE
DECLARE
PRAGMA AUTONOMOUS_TRANSACTION;
totover NUMBER (3);
BEGIN
SELECT COUNT (*)
IN totover
OF THE customer
WHERE: NEW.nric = customer.nric
AND: NEW.badstatus = "Non-payment";
Why are you tring to use an autonomous transaction? All that makes the transaction will NOT be part of the transaction that fired the trigger.
I know there is a problem with the line 13 ' AND: NEW.badstatus = "Non-payment".»
so, how can I go around to solve this issue?
This is the LEAST of your problems. Do NOT try to nontransactional things in a trigger.
Also, don't try to query the table that the trigger is activated on.
This is the fundamental question: Oracle is a multi-user system. Other users may be perform DML on the same table at the same time. So any NUMBER that provides this trigger can turn out to be inaccurate when other users post their transactions.
The best you can do in a trigger is throw an exception. If you do this will affect the complete relaxation and all the lines he treated - not only one line you see that you want to reject.
A requirement like yours needs to be satisfied by the presence of DML performed using functions or procedures and serialize the customer INSERT/update this transaction that a SINGLE session/user/can perform DML on the table for a client given.

How to capture information on what program is inserting/updating of the data in the table?
Hello
I'm working on an application where we have an ABC chart that has a STATUS column. This column is updated from somewhere.However, we are unable to determine where this COLUMN is updated. I checked the DBA_SOURCE table to see if this table is updated from any oracle proc / function. But isn't.
Is there anyway that I can identify what program will update this table? I can create a before update trigger but I'm not sure if that I can capture program (shell script / informatica workflow) that is updated in this table.
You can use in a trigger SYS_CONTEXT 'USERENV' information ' MODULE'
create table mytable ( col1 VARCHAR2(10) , col2 VARCHAR2(50) ); create or replace trigger mytable_bi_trigger before insert on mytable for each row begin :new.col2 := SYS_CONTEXT('USERENV','MODULE'); end; / -- from Toad insert into mytable(col1) values('Test 1'); commit; -- From sqlplus insert into mytable(col1) values('Test 2'); commit; select * from mytable; COL1 COL2 ---------- -------------------------------------------------- Test 1 TOAD 11.0.0.116 Test 2 SQL*Plus
You can also capture a lot more information (host name of the client, the os user, etc.).
See http://docs.oracle.com/database/121/SQLRF/functions199.htm#SQLRF06117

With the help of Merge for Update, Insert, Update and also to delete outdated records
Hi all!!!
Suppose that a credit memo the following table called Orders:
In addition, there are a procedure that will generate data on a global temporary table, called Orders_Temp. This temporary table will be used to update the Orders table. + commands + have a trigger that will perform different operations when an Insert, Update, or Delete command is executed.ORDERID STATUS PRICE ---------- ---------- ---------- 1 0 100 2 0 200 3 0 300 4 0 350 5 0 390
Consider the table of Orders_Temp to have the following data after you run a procedure that is responsible for the update of order data:
As you can see, orders 1 and 2 have been updated. Order 3 and 5 were intact, order 4 has been deleted and command 6 inserted. Fusion will take care of properly manage orders 1, 2, 3, 5 and 6, although producing an update of order 3 and 5, which have not changed.ORDERID STATUS PRICE ---------- ---------- ---------- 1 1 100 2 2 200 3 0 300 5 0 390 6 0 350
So, here are the questions:
(1) how could remove the 4 arrestedorder, as this order was not present on Orders_Temp? Is it possible to use the merge command to do this?
(2) is it possible to generates not a update operation for orders of 3 and 5, which have not changed?
I m using Oracle 10.2 SE.
Thank you very much!
RegisHello
Please try this. Not tested! with 9i. I think you can do this by using the union all.
MERGE INTO orders tgt USING (SELECT A.*, 1 mask FROM orders_temp A UNION ALL SELECT A.*, 0 FROM orders A WHERE NOT EXISTS (SELECT 1 FROM orders_temp b WHERE A.order_id = b.order_id)) src ON (tgt.order_id = src.order_id) WHEN MATCHED THEN UPDATE SET tgt.status = src.status, tgt.price = src.price WHERE src.mask = 1 AND tgt.status != src.status AND tgt.price != src.price DELETE WHERE src.mask = 0 WHEN NOT MATCHED THEN INSERT VALUES (src.order_id, src.status, src.price)
or you could try to use a full outer join and treat NULL values.

No Option to install repair - SAD
HelloWhy Microsoft removed the ability for Windows Vista to install on herself from one location other than being inside the BONE you want to repair.
I recently had a problem where Vista Business 64-bit would only boot to a black screen with a mobile cursor - KSOD. Who, in searching the Web I found is a fairly common problem with Vista. I discovered that my only option was about to reinstall Vista CLEAN and all the other programs I had installed under it. I can't believe that Microsoft released the 'repair installation option"similar to that of Windows XP, where you can hit the"R"key during installation and we left with nothing but the"System Restore"options and"Startup Repair ". Neither of which has helped in my situation. Since then, this was a dual system boot with XP Pro, then any restore point has been removed from the partition to Vista anytime, I started another recognized problem, by Microsoft, which Microsoft has made no significant effort to fix, in addition to recommending that you hide the partion Vista in XP - a whole of XP. That beats a little the entire purpose of dual boot.
As I tried to start in safe mode, it left me at the same point as a normal boot - black screen with a cursor. I tried ctrl + alt + delete and nothing. Two Windows RE options did not help me. This left me no option but to the completely reinstall Vista. Why Microsoft did remove the ability for Windows Vista to install on herself from one location other than being inside the BONE you want to repair.. Please don't tell me that it is because Vista uses an image file instead of an installation as XP system. I see no other reason for not allowing the upgrade of outside BONE in addition to Microsofts greed and paranoia that he can transform the operating system easier to install illegally. I hope that some third party has actually changed the Vista installation routine to allow you to install Vista on itself, because as it is, it's really hard for me to even recommend Vista as the operating system or install any where else, if not the only recourse after loading OS, is to reinstall completely.
Adobe, Autodesk, and almost all other software publishers... allow you to perform a "REPAIR" of their software installation, if something prevents you to load after installation. Even MS Office has a routine repair. Ms has an internal version of the Setup routine which allows outside the OS upgrade option that you want to "Upgrade" / repair? ". If not, why?
-Todd w.
"Why Microsoft removed the ability for Windows Vista to install on herself from one location other than being inside the BONE you want to repair."
«.. . After using XP's repair function, the operating system itself would become less stable and frankly not in a good state of repair. »
As Todd, is the answer."This response does not hold water as on one of my computers I've been running Windows XP for about four years now, after a repair install.
"I thought that this area was a place to really get answers instead of the ole same"answers of bs that are on all the other forums."
If you want to have input on the future of Microsoft operating systems, then help you beta-test and provide feedback to the developers. Windows 7 and IE 8 are currently in beta.
Another possible place you could make suggestions which could see the developers would be:

I try inserting the disk dvd movies and it will play normally. Please give me help with this problem because I want to get my phone to the sound out of the box state. Thank you.
Hello
The drive came with the laptop or you did it yourself in the recovery Partition?
And you're supposed to boot from the recovery disc to start the recovery process.
You change the Boot order to make the CD/DVD drive first in the boot order. Then, you start from the disc.
How to change the Boot order in BIOS:

And as a way to re - install with most of the Toshibas, you press 0 (zero) to start to start the process of recovery back to settings factory (new State) of the recovery Partition.
