• Poor performance during the iteration/update rows of a tree table

  Hello
  
  We have a tree table based on a VO and EO (with transitional attributes). One of the attributes is an indicator.
  The original Version is filled with a complex query with several thousand lines.
  
  Now, when the user clicks on a node, all children are updated (their flag is set to true) recursively.
  
  It's really really slow. It may take several minutes, while a similar update via PL/SQL on a real table would take a few seconds.
  
  Is it possible to improve the performance? We have already applied all the tunings on EO as VO mentioned in the Oracle Documentation, but they had almost no effect:
  -keep the viewlink iterators set line
  -indicators of query
  -Use the batch update
  
  The algorithm we use is the following:
  

      private void checkTreeNodes(JUCtrlHierNodeBinding node, Boolean check) {
          if (node == null) {
              return;
          }
  
         TreeVORowImpl nodeRow = (TreeVORowImpl)node.getRow();
          if (nodeRow != null) {
                  nodeRow.setFlag(check);
          }
  
          List<JUCtrlHierNodeBinding> children = null;
          if (!nodeRow.getLevel().equals("4"))  // no more than 4 levels
              children = node.getChildren();
  
          if (children != null) {
              for (JUCtrlHierNodeBinding _node : children) {
                  checkTreeNodes(_node, check);
              }
          }
      }

  Hello

  try to move the logic of the definition of the transitional indicator at the service of the company (method exposed on the client interface) and then refresh the tree instead of a record thousand on the client component analysis.

• Create a db with a simple form application, based on a remote table

  Hello
  
  I have APEX 4.0 installed on my laptop and a distant DB (always in my local network) with EBS R12 on it.
  I created a dblink with my HR schema and updated my tnsname.ora. Now I can connect and browse the remote db with schema APPS/APPS.
  I can also browse table away from my local db user 'HR '.
  
  for example: select * from emp@apex_dblink; recover data without problem even if I'm a developer sql or standard interface of APEX with my APEX user.
  
  As a training, now I want to create an application database from scratch on a tabular presentation with the HR schema. When I browse for the table, I don't see my table 'emp' remote and when I push the "emp@apex_dblink" research, he said only: "emp@apex_dblink is not a valid table name.".
  
  Some have said, it is because of the 'grant privilege' and 'create the synonym' but I don't know if like my dblink I should think to solve this problem...
  In addition, I do not know much about the administration and do not know where to go...
  
  Here is some information:
  
  DB user: hr/hr@XE
  APEX user: ulrich/ulrich-> name of the workspace: APEX_WORKSPACE
  
  That's your time and your response.

  Apex gets his table & veiw your local database catalog definitions. Are two ways to do what you want:
  (1) create copies of the tables/views you want and create your forms & reports based on these tables/views. Once you have your app work (at least the table/view definitions are now known to Apex), delete local tables and replace them with synonyms for remote tables.

  -- run in local Apex database
  drop table emp;
  -- I'd recommended naming your DB link after the remote DB name to keep easy track of where it's pointing
  -- create database link EBSPROD connect to HR using HR123 identified by 'EBSPROD.world';
  -- or include the schema name if you need multiple DB links to that remote DB
  -- create database link EBSPROD@hr connect to HR using HR123 identified by 'EBSPROD.world';
  -- create database link EBSPROD@scott connect to scott using tiger identified by 'EBSPROD.world';
  -- select * from emp@EBSPROD@scott;
  
  create or replace synonym EMP for EMP@apex_dblink;
  

  (2) create local views to remote objects. Apex point to these points of view the.

  -- run in local Apex database
  create or replace view EMP as (select * from EMP@apex_dblink);

  Someone at - it make a clarification?

  I don't want to insert records into the first time itself. for example, to run the first time he must raise the error. can I do this using MERGE?

  Thank you

  Hello

  Thanks knani, Frank.

  One more doubt.

  When you run the MERGE statement, the first time, there is no rows in the target table, so no rows in the target table is what it is.

  So we cannot perform below sqls using MERGE when the target table is empty?

  insert into tar values (1, 'a')

  updated tar tNom = 'b' set where tnum = 1

  insert into tar values (2, "c")

  Is - that means that the MERGER will be only works with validated data?

  Right; a MERGE statement will not update a line which has been previously inserted into the same MERGE statement.  All fact tables reference to the data in the tables by the time the MERGER began.

  You're complicating things

  A simple MERGE statement will do.

  create or replace procedure (proc_upd_email_records)

  loc_xml in clob

  )

  is

  Start

  merge into e emp3

  a_l'_aide_de)

  Select id

  response

  from xmltable)

  "/ FAX/EMAILOG.

  by the way xmlparse (document loc_xml)

  the columns id number way "ID".

  , path of varchar2 (250) response 'RESPONSE '.

  )

  ) v

  on (e.empno = v.id)

  When matched then update

  Set e.fax_response = v.response

  ;

  end;

  /

  But there is no value added by using these temporary tables if you are not at least an intermediate XMLType column (storage preferably binary XML).

  -What is the version of db?

• Update the values in the Table from another Table containing historical data

  So, I have two tables, a table and a master table.  The current table is updated each week and at the end of the week, is copied to the main table to keep historical data.  I have update the table in progress early in the week and want to take the latest data from the master table and update the current table with the data.  The current table could have additional IDs or some of the IDS could have deposited (these lines would receive data in the main table).  I want to only update the rows in the current table that have existing data to the attr1, attr2, attr3 columns.  A particular ID may have more than one record in the primary table, I want only the last disk to use for updating the current table.  The data from a different database where no direct connection is possible then I have to import data every week.  Here are some statements of create/insert:

  create table current_T (ID1 varchar(100),adate date,attr1 varchar(100),attr2 varchar(100),attr3 varchar(100))
  

  create table Master_T (ID1 varchar(100),adate date,attr1 varchar(100),attr2 varchar(100),attr3 varchar(100))
  
  

  begin
  insert into current_T (ID1,adate)
  values ('IE111','08/02/13');
  insert into current_T (ID1,adate)
  values ('IE112','08/02/13');

• Cannot perform the insert/update on the form of tables, due to the dynamic action

  Hi all
  
  I created a dynamic action that calculates multiple cells in a table.
  
  This feature works well, when I change the value of the associated cell then the computed value is changed by the dynamic action.
  
  But I am not able to insert or update the line in a table when the dynamic action is enabled. When I put the condition 'Never', then the line is inserted or updated without any problems.
  
  All guess where is the problem?

  What is hidden and generated Apex elements are always included in the last cell (td) of the line. Thus, it has nothing to do with the next item, only the last cell.
  If you see the last cell of the 888 Page you will see probably the same type = "hidden" entries here also.

  Your problem is not related to the HTML fragment to the last cell in the row showing all those extra items, it's somewhere else.

  Oh, here comes the jQuery selector:

  var clickedRow = $(this.triggeringElement).closest('tr');
  
  $(clickedRow).children('td[headers="SAL"]').find("input").val(myCalculatedTotal);
  

  SAL, COMM, w/e. here you will find the TD with headers = "COMM" and all the input fields and the value of all the entries in total calculated. Your selection is not precise enough in this case.
  So, target the specific entry.
  With the code example:

  
  Comm
  
  
  
  
  
  
  

  change the switch on

  $(clickedRow).children('td[headers="SAL"]').find('input[name="f08"]').val(myCalculatedTotal);
  

• collection of statistics on a remote table

  Hello
  
  Is it possible and how to collect statistics on remote tables of non-Oracle?
  In my set up an Oracle Server (11g r2) is connected to an Oracle Server remote gateway to Oracle and DB2 server through ODBC gateway. All queries are distributed and heterogeneous, that is, the access data of the two remote servers. The query optimizer uses the real on remote tables from Oracle statistics, while for DB2 tables some default values are used. The difference between the default values and actual statistics is huge.
  I found in a user's guide this column selectivity cannot be collected for tables non-Oracle. Is it possible to collect general statistics such as number of rows from the tables? It would be different if I use DRDA gateway to access DB2?
  
  Concerning

  Ruslan,
  The HS_FDS_SUPPORT_STATISTICS = TRUE parameter is supported using DG4ODBC, even if it is not documented. However, as already said it depends on the ODBC driver and the database non-Oracle to what is returned when set.
  To see if it is used by the pilot, then check track of debug gateway. With the parameter set to true, then you should see explicit SQLStatistics ODBC calls. If these are not present then the parameter is to have no effect. You can also view an ODBC trace for these calls.

• Impossible to get a stable set of rows in the source tables

  Hi guys,.
  
  I use the following query to fusion in a stored procedure.

     MERGE INTO tt_OPEN_IN_TMP B
     Using (Select * From Tt_Sl_Fifo) A 
     ON ( A.Store_Code = B.Store_Code
       AND A.item_code = B.item_code
       And A.Packing = B.Packing
       And A.Serial_No = B.Serial_No )
     When Matched Then Update Set Opn_Fifo_Cost = A.Rate_Bc;

  The procedure raises error * "Unable to get a stable set of rows in the source tables" * as a result of the query. But if I run the query individually, it works very well. Please help me solve this problem.
  
  Thank you
  RAM.

  The error is due to what there is in double store_code, item_code, packaging, combination of serial_no in the Tt_Sl_Fifo table. If there are multiple records with the same store_code, item_code, packaging, serial_no Oracle has no way to determine which to use for the update. If you know that there is whenever duplicates they will all have the same column of rate_bc then instead of using

  (select * from tt_sl_fifo)
  

  use

  (select distinct store_code, item_code, packing, serial_no, rate_bc from tt_sl_fifo)
  

  Or if there is other criteria, like a date column, you can use to determine what is the one you want to use to day then you can use something like

  (select store_code, item_code, packing, serial_no, rate_bc from tt_sl_fifo
    where (store_code, item_code, packing, serial_no, add_date) in
         (select store_code, item_code, packing, serial_no, max(add_date)
            from tt_sl_fifo group by store_code, item_code, packing, serial_no))
  

• Display and update of fields in different tables on the same page.

  I am facing two problems...
  
  (1) I have a report on which I show several fields of 4 different tables. For each row of data, there is a link to change on the first column. By clicking on the link change, I show you a form where I want to show the respective data. On the link change, even if I send you the data in the report, they do not appear on the form (what edit link is clicked). Also, there is only room for 3 items to ship through the link change.
  How to display the data correctly on the form? Is there another way to use the link change?
  
  (2) on the form, how do I update the data from different tables?

  Hi Lisa,

  The text of presentation on the INSTEAD OF triggers is in: [http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_7004.htm#sthref7918]

  First of all, your SQL View contains a unique key so that your triggers and the two Apex know what is updated.

  Then, you can create instead of triggers for "instead of INSERT ON viewname", 'instead of UPDATE ON viewname' and 'DELETE ON viewname' on your SQL view. What do these triggers depends on what you need. In the trigger code, you refer to new data using: NEW.column_name and old data using: OLD.column_name (updates both: OLD and: NEW values).

  I'm not sure of the SEPARATE, the GROUP IN question. You would certainly have a unique key on each record. It could be that the DISTINCT or GROUP BY clause will have to be taken out of the SQL view and is part of the source of the region, so that the SQL view does nothing with the data other than to join several tables in a single "table" from the Primary Key/Foreign Key relationship.

• Download massive updated the planned orders in table msc_supplies

  Hi all

  I need your suggestion below requirement:

  For item RM, we planned order suggested that the CPHA; before releasing it, we want to change Date of implementation and the amount of order, then output the last modified scheduled released automatically to create the PR in purchases & Payables.

  In order to change the planned orders of RM, we export order planned the Workbench of the CPSA in the worksheet and then change dates, quantity, etc. in the worksheet. We want this change data to insert in the table msc_supplies automatically with manually intervene them and followed by releasing these planned automatically orders to create a PR

  We want to know how to achieve this requirement. We want to know the available custom hook and script to insert record in to msc_supplies.

  Have a great day.

  Thank you

  Sanngo

  Hello

  We expect steps below:

  (1) export the planned RM command suggested by the CPSA to the spreadsheet or report.

  (2) prepare the csv file with mandorty field as shown below in the table, i.e. date, quantity, etc. and format the data according to the custom intermediate table created.

  (3) custom concurrent requests created, which is used to locate the data file and upload the data to a custom intermediate table.

  (4) of the intermediate table that we are download the same data in the database MSC_SUPPLIES table (make a validation here check) in the same program. After that a manually scheduled commands added to the table of MSC_Supplies and can be found in the CPSA workbench.

  (4) in the same concurrent application of custom, call "automatic rejection" to release these records of the base table of msc_supplies, where release_flag a value of 1.

  We want to know the required fields need to be updated in the staging table custom and the base table:

  ORGANIZATION_CODE ORGANIZATION_ID

  ITEM_SEGMENTS INVENTORY_ITEM_ID

  ORDER_TYPE_TEXT ORDER_TYPE (5)

  New Date FIRM_DATE

  New quantity FIRM_QUANTITY

  Argument Plan_ID

  Transaction_id

  RELEASE_STATUS (1)

  SR_INSTANCE_ID

  You can test adding the manually planned adhoc decrees on Workbench CAWC namely, which are updating fields in the MSC_SUPPLIES table.

  Have a great day.

• Update multiple columns from multiple tables in a single UPDATE request

  Hello

  I'm trying to figure if I'm heading in the right direction.

  I want to update multiple columns from multiple tables in a single UPDATE request. Also, I would like to update multiple columns in a table from the tables.

  Scenario 1

  UPDATE Table2, Table 3
  SET T2.Column1 = T1.Column1 
  ,T2.Column2 = T1.Column2
  ,T3.Column2 = T1.Column2
  FROM Table1 T1, Table2 T2, Table3 T3
  WHERE T1.id = T2.id
  and T1.id = T3.id
  
  

  Scenario 2

  UPDATE Table3
  SET T3.Column1 = T1.Column1 
  T3.Column2 = T1.Column2
  ,T3.Column3 = T2.Column3
  ,T3.Column4 = T2.Column4
  FROM Table1 T1, Table2 T2, Table3 T3
  WHERE T3.id = T1.id
  and T3.id = T2.id
  
  

  Hello

  For scenario 1, you must write separate instructions UPDATE table2 and table3.

  To guard against someone else change one of these tables while you act so you can copy all relevant data in a global temporary table and update this global temporary table table3.

  ENGAGE only when two tables have been changed.

  You can write a procedure or an INSTEAD OF trigger to do all this.

  For scenario 2, you can reference many tables that you need when new table3.  It might be more efficient and simpler to use the MERGER rather than UPDATED.  For example:

  MERGE INTO table3 dst

• How to rename the table or synonym?

  Hi all

  11.2.0.1

  I want to rename the table or synonym owned by HR as a SYS user.

  SQL > rename hr.emp in hr.emp_old;

  ERROR on line 1:

  ORA-01765: specifying the name of the owner of the table is not allowed

  Thank you very much

  Hello

  You can do something like that as a user of the SYSTEM:

  1 alter session set current_schema = "HR".

  2. Rename emp emp_old

  Thank you &

• Presentation tabular - when the updated row, add a user id and a time stamp line.

  Hello.
  I have a simple tabular presentation based on a table of four elements: the primary key (seq #), title, Updated_by, Updated_timestamp.
  I want to fill the Updated_timestamp and updated_by fields when a user updates or adds to the table.
  On other forms, I use a calculation to update the page_item in section page_processing of the APEX. However, in the form of tables, I don't know
  where I can update these two fields.
  Any suggestions?

  Thank you! I think the trigger is the way to handle this. Thanks again.
