• Best way to update all the lines of a huge table

  Hi all

  I'm on Oracle 11.2 Enterprise edition.

  I asked a question, "assumes that there is a large table, say 3 GB size.» We need to update all rows in this table (e.g. col3 = col3 * 2), what is the best way to do this? »

  My answer was, there are 2 possible ways, depending on the number of indexes on the table

  (1) if there is a lot (or wholesale) index on the table OR the database is in FORCE LOGGING mode (due to log shipping), I just run an UPDATE command on the table and update all records. This will generate a lot of redo and undo, but we cannot do anything for indexes

  (2) if there is not a lot of clues, I'll create an empty table of the same structure (create table t2 nologging in select * from t1 where 1 = 2). Then, using an INSERT... AS SELECT... command, with the ' col3 * 2 "instead of col3, I insert any data into the new table with APPEND tip. Then create all indexes on the new table and finally, rename T2 T1

  In case the first solution, I can avoid the recreation of the index and save this I/O. In the case of newspapers, first solution makes more sense anyway.

  Second solution is logical, if we have the freedom of creating objects in NOLOGGING mode.

  What do you experts? I think in the right direction? or what?

  Thanks in advance

• Form master / detail apex 5 tries to update the lines of details without apparent change

  A form master / detail of Apex default 5.0 creates buttons back and forward on the main table. When you move between records, the detail region launches a message: update 0 row (s), 0 or the inserted rows.

  Glance in occasional of the user, it will look like a mistake: I, what has changed and why it has not been saved?

  If nothing has changed, why is a MRU statement update being generated?

  How do I remove this behavior? Is this a bug?

  Hello

  Create a new hidden element Px_RUN_MRU and the value of

  Source used "Always replace the value that exists in the session state."

  Source of Type ' static assignment (the value corresponds to the source attribute) ' and

  Value of source or phrase "N".

  Then create new PL/SQL process for tabular and use the code

  if :Px_RUN_MRU = 'N' and :APEX$ROW_STATUS IN('C', 'U', 'D') then
    :Px_RUN_MRU := 'Y';
  end if;
  

  Make sure that this process is captured in the form of process MRU.

  Then change tabular MRU to love affection

  (:request like ('SAVE') or :request like 'GET_NEXT%' or :request like 'GET_PREV%')
  and :Px_RUN_MRU = 'Y'

• Master-detail - page updated

  Hi all

  I implement updated for logic with master-detail page.

  My expectations:

  Both master Vo and Vo of detail is executed with Set whereclause and line master and detail gets displayed.

  The two actions are required in the application process.

  Result:

  Executing query (even after call run the query for master and detail VO), master line get appears. Detail line is not displayed,

  

  However when the form application process is called (by clicking on the button Save), detail lines gets displayed.

  My logic to query example: (your have VL and EOs have AO)

  PR:

  Configuration where clause;

  XXAM.getXxcfirIcfUpMasterVO1 () .executeQuery ();

  XXAM.getXxcfirIcfUpDetailVO1 () .executeQuery ();

  PFR:

  The logic of adding new line-to-line in detail.

  Save button.

  Is there a way to show line main and details while that Page gets loaded through the application process and still not break the relation ship master detail since must be made on the update page.

  Thank you and best regards,

• [ADF, JDev12.1.3] master / detail af:tables the link is handled by ExecuteWithParams: how to create a master report / detail in a loop on the lines?

  Hallo,

  I have a page with 2 legs and they both contains an af:table created by dragging an instance of VO in the user interface.

  The 1st tab uses a master VO while the 2nd uses a VO detail.

  Between 2 your, there is not a link of VO master / detail.

  Opening Details tab I update the secondary table by calling the method ExecuteWithParams of the detail VO instance (in a managed bean).

  I would now like to generate a report that loop on the master table and that, for each line of master:

  • He writes in the report;
  • loops of registration of details (which are based on the master record) and also writes the report.

  
  

  Could you kindly suggest me which is the best way to achieve that through a code to write in a managed bean?

  Here I am interested how do to loop through the data, not in how to write the report.

  Thank you

  Yes it will affect the selected line. If you want to ignore try using this code

      DCIteratorBinding iter = (DCIteratorBinding) BindingContext.getCurrent().getCurrentBindingsEntry().get("DepartmentsView1Iterator");
      ViewObject vo = iter.getViewObject();
      for (int i = 0; i < vo.getEstimatedRowCount(); i++)
      {
        Row r = vo.getRowAtRangeIndex(i);
        System.out.println("DeptId= " + r.getAttribute("DepartmentId"));
      }
  

• Master / detail. Third do level not updated, if the second tier is not returned

  We have three level model master / detail.

  The first and the second level is 1 to 1

  The second and third are 1 to *.

  The second level is just an empty container from now and should not be displayed to the user. But it takes to get the first level to the third level.

  If make us only the first and third level tabulated, the iterator behind the third level table is not correctly being updated, actions.

  If we make on the other hand, the second-level table, the iterator for the third level table IS updated, to action - such as changing the current line.

  We worked arround by 'hide' the second table level in a group separator collapsed. Is there another way to get arround this problem?

  Top-level iterator:

  < iterator lie = "First" RangeSize = '25'

  DataControl = "AMDataControl" id = "FirstIterator".

  ChangeEventPolicy = "ppr" / >

  Second level iterator:

  < iterator lie = "Second" RangeSize = '25'

  DataControl = "AMDataControl" id = "SecondIterator".

  ChangeEventPolicy = "ppr" / >

  Third level iterator:

  < iterator lie = "Third" RangeSize = '25'

  DataControl = "AMDataControl."

  ID = "Third" ChangeEventPolicy = "ppr" / > "

  Not sure, but maybe you can use custom (for the first table) table selectionListener, I you must refresh the second iterator of pageDef...

• Master / detail prevent insertion line detail if the master does not exist

  Hello
  
  I have a complex page that has several pairs of master / detail on it. I have what should be a simple problem to work around that I can't understand. On each table (master or detail), I have a button create header and a delete button in each row. I have a few questions, I can't seem to cross.
  
  1. how to turn off the details create button if there is no master of the line or one has not been selected by the user? (At the moment you can create detail without a valid master line rows)
  2. how to disable the removal of main line button, if there is (or not) details of current lines?
  
  I think I only got 2 having a transient attribute on the main line that uses groovy and the accessor to link views to count the detail rows. It seems to work, but if there is a better solution, cleaner I'm all ears. I can't seem to operate 1 little matter what I try.
  
  Thanks for any help you can provide.

  Hello

  You can use iterator estimatedRowCount to disable the button of

  disabled="#{!(bindings.mastervoIterator.estimatedRowCount ge 0)}"
  

  and use the currentRow determint property if the current row is selected as

  disabled="#{!(bindings.mastervoIterator.currentRow ne null)}"
  

  Thus, the combination will be as follows

  disabled="#{!(bindings.mastervoIterator.estimatedRowCount ge 0 and bindings.mastervoIterator.currentRow ne null)}"
  

  I hope this helps...

  Kind regards.

• Master / detail: several lines in detail are selected default

  Hello world

  I use Jdev 12 c and facing a problem, in a scenario of master / detail, several lines are by default selected in the secondary table, I checked the line selection unique option in the configuration of the table. Please see the snapshot for clarity.

  You normally see this problem when the vo or eo is not a primary key defined. Check that each OT and vo should have a defined primary key that is unique for the vo.

• Update of Varchar2-PrimaryKey in master / detail

  Hello

  I use a form master / detail with a primarykey as varchar2 in apex 4.2.

  When you try to update the primarykey value in the detail form, I get a ORA-01403: no data found.

  Is there a way to avoid this problem easily?

  Thanks in advance...

  In my humble OPINION, easist way... to serve another PK column and make it editable and free to the top of the current "PK" column for editing and apply own forced him (Unique, etc.)

  the column you are trying to update in the form of details and use as PK is a bad choice if you need to update.

• Updating of the master/detail does not work after the failure of the validation

  After validation of the judgment of the further processing of a page page page master detail, I get the error message Oracle depending on the display of the detail portion:

  < code >

  ORA: 01445: cannot select ROWID, or sample, a view of join without key preserved table.

  ORA-06510-PL/SQL unhandled exception defined by the user.

  < code >

  
  

  Clues as to why this might happen?  The master of the page displays fine as well as the validation error message personalized appropriate. It's just part of detail (from SQL-based report) that is causing the problem.  I use either a ROWID.

  
  

  Thank you!
  

  Just an info for all those who may have this same problem in the future.  I corrected the error and it had nothing to do with the ROWID or views or something like that.  Under the section of Page rendering when you set the definition of the region in the source section, I included the "order by" clause in my SQL statement.  This was the cause of my ORA-01445 error!  When I removed the clause of the definition of the source, and instead included in the attributes report by checking the box of the appropriate column sorting (which allows the apex generate so for me), the error has disappeared!  The error message Oracle NEVER would have given me a clue to what caused the error.  I joined just thinking 'what if I take the order by clause.  What's a flukey fix!

• Creating a master automatically when you create a detail line

  Hello

  I use Jdev. 11.1.2.3.0

  I have three tables (with their corresponding objects in the view) with a master/detail/detail relationship.

  Retail first level table contain a maximum of one line for each line of master.

  The ID of the level of the first and second level details are generated automatically with a groovy expression and a sequence.

  Views are added to the page as a table(master/) form (retail) /table (retail).

  I have a case where a master record has no detail and I need to create a new line in the secondary second-level table.

  So is it possible to say ADF to automatically create the detail row of first level (given that the captain is known)? or should I manually check that there is no such a line in the detail at the level of the first table and then create it before you create the line in the secondary table of second level?

  Thank you.

  No, there is not this option if you need to manually create this line.

  Set to true, Tony. My answer was assuming programming experience. It also leaves open the option to default to a value that the user is able to change (even if the two examples given in the original post are probably not something that the user should be handle); triggers would force a value without allowing the users to substitute them.

• clear lines of your master / details

  Hello

  I use jdev 11.1.2.4.

  I have a master details page for the reception tables and receipt_detail. I created a relationship of foreign key to the DB level.
