• DML operations in arrays of relationship of m: n

  Hi all

  I use jdevelopper 11.1.2.4.

  
  

  I'm m: n between two tables A and B represented in an array of C. something like:

  Table A:

  • A_id
  • A_data

  Table B:

  • B_id
  • B_data

  Table c:

  • A_A_id
  • B_B_id

  My use case is: I want to show and allow the DML operations for the table rows B associated with a specific id of table A.

  to add a table A children, I have to check if the reference is already exists in the table B if so I only create the conjunction a line in table C. If this isn't the case, I should create a row in table B first.

  for this I use 3 objects in the view: (VO1) on (table A) and (VO2) (updateable table B and table C as reference). and VO3 (on table C).

  so I use a relationship master / detail between this your.   A_id (VO1) - A_A_id (VO2)-. A_id (VO1) - A_A_id (VO3)

  the result is:

  VO1

  |_VO2

  | _VO3

  and a function to add a child:

  public String addChild (reference String) {}

  Boolean exists = checkIfExist (reference);

  If (! exists) {}

  DCIteratorBinding iter = (DCIteratorBinding) UtilityBean.getBindings () .get ("VO2Iterator");

  Line = iter.getRowSetIterator () .createRow ();

  row.setAttribute ("B_id", B_B_id);

  iterBien.getRowSetIterator () .insertRow (row);

  }

  / * Iter = (DCIteratorBinding) UtilityBean.getBindings () .get DCIteratorBinding ("VO3Iterator");

  Line = iterEvtBien.getRowSetIterator () .createRow ();

  row.setAttribute ("A_A_id" ,A_id );

  row.setAttribute ("B_B_id", B_B_id);

  .getRowSetIterator () .insertRow (row) ITER;

  DCIteratorBinding iterBien = (DCIteratorBinding) UtilityBean.getBindings () .get ("TitresReponse1Iterator");

  iterBien.getViewObject () .executeQuery ();

  */

  Returns a null value.

  }

  But it does not work if I do not call the validation after the set of operations.

  Thank you to.

  When your function is called by a select statement, an error is triggered because of rule1).

  When your function is called in an insert statement, no error is raised. The insert does not work in parallel (this is an insert row after all). So rule1) is also not infringed. The insert is on the table2, change table1. Because it does not modify the same table rule2) is not violated. So no reason to trigger an error.

• Why bitmp index are not suggested for DML operations

  Hi all
  
  Can someone make me understand why bitmap indexes are not suggested to use for DML operations. AFAIK, the reason being that it locks the table and another user won '; t be able to complete the transaction but why?

  user13389425 wrote:
  the reason is that I found is that it stores the rowid of beginning and the end rowid and the value of the spreadsheet store n number of entries of the inder, so any operation DML whole leaves lock themselves and cause the performance of the database. My next question I was not able to address, is that the index entries how do I store it on a single sheet. How calcualte the same.

  It is not the entire sheet that gets locked, just the specific index entry in the block sheet index, as well as the corresponding lines in the table referenced by the rowid ranges in the index entry.

  As an indication, the average number of index entries in a block of sheets is the num_rows/leaf_blocks in dba_indexes. As an example, the average number of rows in the table referenced by the index entry is (num_rows in dba_tables/num_rows in dba_indexes) * distinct_keys in dba_indexes.

• Best approach to the DML operation in App Impl method

  What is the way of best/right to the DML operation in AppImpl methods. getDBTransaction () sets / statement or to create an object of connection directly from the data source and make DML operations?
  
  Thank you
  Bastien

  If you want to call a PL/SQL API, then by all means, use the connection of AOS (getDBTransaction()).

  Is there any problem of concurrency using getDBTransaction()

  As long as you follow the process appropriate (i.e., putting the service methods in your AM and call them through the link layer), you will be fine.

  That will mean he commits a user the changes regardless of the changes made by the other user also get committed to the db?

  NO.

  Have a [url http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/bcadvgen.htm#sm0297] read the docs to see the proper approach.

• Mr President, how to find the last DML operations

  Hello
  
  Please tell me how to find the last DML operations at least a minimum of 30 queries.
  
  Thanks in advance,

  Select sql_id, sql_text, last_load_Time from V$ SQLAREA

  or

  Select * from v$ sqltext

  Must be one of them. But don't know what exactly you are looking at.

  I usually use v$ sqlarea to see recent queries.

  Maybe you can limit the rows using rownum, order of last_load_time.

  I understand, if the same query is used again then only recent transaction is stored.

  m sorry sb92075, I guess I wrote wrong...

  I got DBMS_LOGMNR, but do not know how this will help me to above case... check once more.

  Thanks again!

  REDO file contain all DML against the DB.
  Dbms_logmnr can show who did it as DML & when extracting these files REDO details.
  I thought that this is the question you want answered.

• No DML operations on a table

  Hello
  
  In fact, my problem looks like an easy question, but the truth is that I think that it s quite bizarre.
  
  Check out Let´s:
  
  The first time I noticed about who was a few days earlier in the morning, I got 100% cache libray locking from and export complete simple all night.
  
  After killing the process I discovered that the real problem is that Oracle can´t access a table, if I try to do any operation DML on this table, the library cache continues up to 100%
  
  Same thing happens if I try to 'select count', 'desc', 'delete', 'truncate', 'Add pk', 'drop pk', "alter index", "drop index"... everything I try with this table returns the same question, it freezes SQL and create shortages.
  
  Metalink says I should try to restart the database, maybe it's a good idea, but it is production environment with Linux Red Hat Cluster shared drive thinking, so if I restart it and Oracle can´t start... I'll be in real trouble...
  
  Any idea/s...

  I think that 'something' is using this table. Here are a few checks I would do:

  -Try to run a "analyze table... validate structure.
  -Select * access $ v where object = "your name of the table."
  -Examine the follow-up and alert.log under user_dump_dest/backgroup_dump_dest files. for example, you might find errors that could explain your problem.

  In addition, do you see not all the locks on that table? is - that is it possible that a process modified a large number of lines and no clerk has not yet? Are there numbers moving up/down under the terms of the transaction$ v?

• trigger dml operations

  Hi all

  Hope all are doing well, I need a trigger (DML opereations) update one table if another table Gets the updates but I m not good in plsql, so I need your help, if anyone has, could you please share this trigger? your help will be appreciated, thanks in advance.

  Thank you.

  Kind regards.

  OS: RHEL 6.1

  DB: 11.2.0.3

  User,

  Using the above code, it will not update the name also.

  Trigger: OLD.name will store the old value and: NEW.name will store the new value.

  You must use

  UPDATE testcp SET name =: new.name where id =: old.id;

  This will update the new value to the name field in the testcp table.

  If you want to update the id also try this:

  UPDATE testcp SET name =: new.name, id =: new.id where id =: old.id

  See you soon

• Facing a problem while doing DML operations in Discoverer (Urgent!)

  Hello
  
  I am facing a problem in the discoverer report I'm working. I would be grateful if you could help me find a solution for this-
  
  I'm releasing a custom package of discoverer. This package is the insertion of data in a custom table. As we cannot directly put the DML statements in the package of discoverer so that I have defined this package as the Pragma autonomous. The custom table that is being filled is an ordinary table (that is not a global temporary table). In the folder custom in Administrator I just selects the custom table data.
  
  Problem when I run the report of discoverer, the data get inserted in the custom table, which means that the package is working correctly, but still the report does show all the data. Maybe the running query before even that data is inserted in the table. Can you please what Miss me in this solution?
  
  Some facts of the report-
  1. I use that only one worksheet.
  2. the packaging is insert the data in the custom table, so I see no problem with the package and trigger.
  
  Thanks for your help.

  Hey Anshul
  Now, I understand, and you certainly don't want a user data of another user overwriting data.

  An idea that comes to mind and the other I did have to create a copy of the table in the schema for each user who needs. There will always be an original copy in the main schema. So what you need to do is to create a local synonym for the table, in the schema of the user who performs a redirection of the system to use the local table. Using this approach you can have each user, update their own copy and read it for their reports.

  Another, more difficult the idea would be to use a TEU, private virtual database, to control the data in a central table. The table would not be truncated, but would have a new column added to the owner of the data. Then during the execution of the procedure it delete all the lines for the user and then load new ones for this user. The CAE would be used to filter the data in the report so that the user sees only the data belonging to the user.

  Hope that all makes sense. The first is that I would like to try because it is the simplest.
