• The separate display - process success Message - for INSERT/UPDATE/DELETE

  Hello
  
  When we either Insert/update/delete records of shape of the APEX, it fires the Page - processing of automatic line (DML) process and displays the following message - process success Message
  
  -File has been processed.
  
  Is there a way for each of them, we can change this message...
  I mean, if the creation of a new record - message should be - record has been created... his way... If update... * manual has been updated *... and so on...
  
  Thank you
  Deepak

  Hello

  One way is to create a component hidden from this page and calculation value according page submit the request.
  for example if the application is updated then the item value record has been updated.

  Then put this point to the message of successful treatment of automatic line (DML) as & Px_YOUR_ITEM.

  Hope this helps

• Insert, update, delete

  If I have a cfquery with the data name and relevant source etc. then the sql will be the same for:
  
  1 insert, update, delete with mysql and mssql?
  2. trade unions and different joins for mysql and mssql?
  
  Thank you!

  When you compare two db, it is reasonable to assume that they will behave the same if you stay plain vanilla sql and that there will be at least a difference when it comes to features.

• Insert, update, delete logging

  Hi friends
  I have insert, update, delete the table from the journal as
  
  TableName, rowname, date, user, type of operation
  
  for example, user delete a line, I see in my journal but sometimes I want to deleted data in rows.
  with oracle do we find data?
  or
  We can find data another way?

  Look at this example, hope you understand the question

  SQL> create table my_tab (id number, name varchar2(20));
  
  Table created.
  
  SQL> create table log_my_tab (old_id number, new_id number, old_name varchar2(20), new_name varchar2(20));
  
  Table created.
  
  SQL> create or replace trigger trg_test
  after insert or update or delete on my_tab
  for each row
  begin
  if updating then
  insert into log_my_tab values(:old.id, :new.id, :old.name, :new.name);
  end if;
  end;
  /
  
  Trigger created.
  
  SQL> select * from my_tab;
  
  no rows selected
  
  SQL> select * from log_my_tab;
  
  no rows selected
  
  SQL> insert into my_tab values(1,'Kamran');
  
  1 row created.
  
  SQL> update my_tab set id=2,name='Agayev' where id=1;
  
  1 row updated.
  
  SQL> select * from log_my_tab;

  As see you in this example, I create two tables, a main table and another table of newspaper. But in addition I create a trigger to track updates and insert old and new values to the log table

• Insert, Update, Delete on a partition table not even at a time

  Hello
  I have a non-partitioned table on which inserts, updates and deletes come at the same time due to which I am facing problem of contention.
  What would be the ideal solutions to solve my problem (deletion conflict.)
  
  Thank you
  Badin

  Can you give us more details on the "problem of contention"? This could mean a very large number of different things.

  You have different sessions simultaneously update the same row in the table, for example? If so, you probably need to look at the architecture of the application to avoid multiple sessions to the same line at the same time setting, or you would need to look at the data model to avoid multiple sessions to update the same line at the same time setting.

  But there could be dozens of other kinds of claim that you could talk.

• using postings in insert/update/delete

  Hello all;
  
  I'm so confused right now... I have read several articles on this subject and I don't know who is good or bad
  
  If an update statement is written in a client front-end as asp.net, must hire us or not, or should leave us it to auto-commit
  This scenario applies with an insert as well

  If you ask from the point of view of determining what is best practice

  Autocommit is evil and should be avoided at all costs. Unless you really, really, really understand what you do, a request that autocommits will end up with data in an inconsistent state. Unless the developers are extremely cautious, a page that allows you to transfer money from one account to another, for example, eventually sending statements to withdraw money from an account and drop it into the other and autocommit will cause to commit inadvertently withdrawal when filing statement fails.

  If you ask from the point of view of what are the technical requirements

  If you are in the mode autocommit, it is useless to engage in explicitly all the instructions (of course, you also won't be able to restore all the instructions explicitly)
  If you disable auto-commit mode, you will have to validate each transaction explicitly. After all never transactionally consistent of the DML statements (INSERT, UPDATE, and DELETE), you will need to do a commit explicit or an explicit rollback. In the example of transfer of account, you would hire after that withdrawal and the filing of declarations had been executed successfully. When you close a connection, your frame can do an implicit validation or cancellation (it depends on the frame) but who should not be trusted.

• Why performance degrades overtime when insert/update/delete VARBINARY?

  I use TimesTen directly related. I created a table with a column of type VARBINARY (100000). My test program inserts a line of 8K bytes in this table, then updates that row with another 8K bytes, then finally deletes this line. If I do the insertion/upgrade to update / delete 10000 times in my program, the number of performances is about 8000 operations per second. But if I do 300000 times, performance is about 4000 transactions per second.
  
  I do not understand why the performance degrades over time? Anyone understand it?
  
  Thank you!

  Based on the workload that you describe, and the fact that you see LOG_BUFFER_WAITS increasing this is likely to be the main problem here. Increasing the size of the log buffer and the size of the file should reduce or eliminate this problem. Depending on the type of disk array and how it is configured, you can still see a performance impact when checkpoints occur if the log files are on the same set of disks than the newspapers. Let us know how you go.

• Restrict the insert, update, delete the other user table

  I created a new database user. I have granted the privileges system into a TOAD.

  • Select any table
  • alter any table
  • delete a table

  I found that account can select, alter, drop table arrays of other schema. So how I can limit the which account to modify, remove only its tables belonging and select table of all the schema?

  Is there the ALTER table, ALTER view, ALTER procedure, ALTER synonym, DROP table, DROP view, DROP procedure, DROP synonym system privileges? How can I grant it without ANY system privileges?

I have also read data from the table and display it in the same format. Please let me know how to proceed in the apex.

  instead of using the null value, you can use apex_item api to create checkboxes

  You can set the value of checkboxes using apex_item api, then the value may be captured in your process of

• Component ODI OWB 11 GR 2 How to connect lines inserted/updated to update / delete

  Hi experts,
  I developed an ICT KM which will insert into a target table data line-by-line, I used the ICT_SQL_INCR_UPD_ROW_BY_ROW KM of base provided by oracle, what I noticed, is that this newspaper does not work lines that are inserted as other KMs, after that a little research on the internet discovered that ODI has a function for this , oidRef.setNbInsert, but this doesn't work in OWB KM, it gives this error:

  Hi CIPI

  Unfortunately, it is not included, the only possible audit for lines is via JDBC and properties explanations in KM.

  So not every API of ODI is supported, a large common subset is available, you can see the doc for more details (these audit would be useful);

• Is the sequence of the insert/update issue?

  Dear friends
  I wanted to know if there is a difference in the results, if I change the sequence of Insert/Update statements. For example, if I insert / update of the records in a table, normally I write my code like below
  
  < code >
  
  Begin
  Insert in the Table Name (...)
  Values (...);
  Exception
  When Dup_Val_On_Index then
  Update entire Table name
  Column_Name = Value;
  While others then
  SQLERRM;
  End;
  
  < code >
  
  Lets assume, if I change the order of statements like below:
  
  < code >
  
  Begin
  Update entire Table name
  Column_Name = Value;
  If Sql % NotFound then
  Begin
  Insert in the Table Name (...)
  Values (...);
  End;
  Exception
  While others then
  SQLERRM;
  End;
  
  < code >
  
  If this change makes no difference in the bottom line?

  I highly recommend the use of MERGE - make an update-so-insertion or insertion-so-update leaves you open to the clashes during two sessions try and add a new line at the same time.

  If you are not able to use MERGE for whatever reason, then I would work out who is most likely to happen - an insert or an update and do that first, followed by the other in the exception.

  For example. If your system inserts rows into the table in question a lot, but only updates rarely, so first the insert and manage the update in the exceptions. Conversely, if your system updates a lot but doesn't insert only rarely. In this way, you are minimizing the amount of work you have to do.

  Opt for a MERGER if possible, though. I don't know Oracle Forms, but can you not to call a stored procedure that could do the MERGE if you are not able to use MERGE directly in forms?

• Impossible to delete the record from the table using the form

  I have a stored procedure (function, actually) that allows an administrator to manually delete a record in a table.
  
  When I call my form there will be no effect. The record remains in the table.
  
  In both cases, I connect to the database to the same user.
  
  I am able to call a test function in the database which returns a field in the record, so I think I can at least communicate with and retrieve results from the database using a stored function. As soon as I approach him "select" "delete from", no luck.
  
  If I try to run the SQL in my form with a statement of FORMS_DDL, it seems to run smoothly when I not in the code in the debugger, but it had no effect. FORMS_SUCCESS reports TRUE if DBMS_ERROR_TEXT has the following: ORA-01403: no data found. I don't know how the DBMS_ERROR_TEXT is that FORMS_SUCCESS is not set to FALSE.
  
  Any ideas as to why I am unable to remove using my form but can when you call the function registered directly/manually?

  Patrick,

  After each Insert / Update / Delete statement, you have to COMMIT . Then only it will be in select statements.

• 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:
  

  ORDERID        STATUS      PRICE 
  ---------- ---------- ---------- 
           1          0        100 
           2          0        200 
           3          0        300 
           4          0        350 
           5          0        390

  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.
  
  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:
  

  ORDERID        STATUS      PRICE 
  ---------- ---------- ---------- 
           1          1        100 
           2          2        200 
           3          0        300 
           5          0        390 
           6          0        350

  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.
  
  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!
  Regis

  Hello

  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.

• 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.
