• PPR for the updating of the table after a click in a butto in Jdeveloper 10.1.3 - thanks

  Hi people,
  
  I looked through many messages about refreshing the page, but still did not solve my problem. Please help me. It's quite URGENT.
  
  I have a table with a command button. After you click the data insertion is engaged and the table is supposed to be updated to reflect the changes.
  
  Now I use PPR as my solution: the button is the initiator and the table is the target. I put the button property: part delivery = true and its id as a partial release of the table value
  
  What I missed, please?
  
  Note: reloading of the entire page is not a solution for me. (The table is incorporated within a region of showOneTab and there are other tables in different tabs)
  
  Thanks in advance!
  Assuming that nothing wrong with the JavaScript syntax, the explanation might be: If you ActionListener Installer (data transaction method) and javaScript on a button-click the button, the button click javaScript will not be executed. (???)

  This is not the case. In my application, the two actions of script and java onclick button are executed. Javascript onclick fires first, then the action of the button. It should be the same for actionlistener as well.

  Regarding the updating of the table after a click of a button inside the table, you can do this by forcing the partial relaxation of the table of a bean to support using addPartialTarget.

  On the actionListener to the button call the below the backup method of bean.

  Here is the code example:

      public void btnSample_actionListener(ActionEvent actionEvent) {
         // First execute the method on the button
         BindingContainer bindings = getBindings();
          OperationBinding operationBinding = bindings.getOperationBinding("buttonMethod");
          Object result = operationBinding.execute();
  
          //Refresh the iterator of table and partial trigger the table
          OperationBinding operationBindingTab =
              bindings.getOperationBinding("RefreshTable");
          Object resultTab = operationBindingTab.execute();
          AdfFacesContext.getCurrentInstance().addPartialTarget(myTable);
  

  RefreshTable is an action that runs the Execute method on the table iterator.

  Thank you

  If you have saved the file name in the database, it's pretty simple.

  echo '';
  

  Is the same for the box:

  echo '';
  

  If you have saved the image file in the database, it is much more complicated. I recommend you store only the file name in the database.

• SQL Loader loading data into two Tables using a single CSV file

  Dear all,

  I have a requirement where in I need to load the data into 2 tables using a simple csv file.

  So I wrote the following control file. But it loads only the first table and also there nothing in the debug log file.

  Please suggest how to achieve this.

  Examples of data

  Source_system_code,Record_type,Source_System_Vendor_number,$vendor_name,Vendor_site_code,Address_line1,Address_line2,Address_line3

  Victor, New, Ven001, Vinay, Vin001, abc, def, xyz

  Char Source_system_code (1) POSITION "ltrim (rtrim (:Source_system_code)),"
  Record_type tank "ltrim (rtrim (:Record_type)),"
  Source_System_Vendor_number tank "ltrim (rtrim (:Source_System_Vendor_number)),"

  Address_line2 tank "ltrim (rtrim (:Address_line2)),"
  Address_line3 tank "ltrim (rtrim (:Address_line3)).
  )

  the problem here is loading into a table, only the first. (Table 1)

  Please guide me.

  Thank you

  Kumar

  When you do not provide a starting position for the first field in table2, it starts with the following after a last referenced in table1 field, then it starts with vendor_site_code, instead of $vendor_name.  So what you need to do instead, is specify position (1) to the first field in table2 and use the fields to fill.  In addition, he dislikes when 1 = 1, and he didn't need anyway.  See the example including the corrected below control file.

  There now things are clear... whenever I have free I'll post the code u how to do this...

  for now, a few tips can help u

  -create the table to store operations travel so then u can't fix your code

  -Create the cursor on the T1 line through all the records.

  -Control what empno and action i.e. the current cursor (I or O) exists on the same date in T2 or not

  -otherwise exists insert a new record check also the SHIFT is coming in time IF is between MAJ 0815 and 1645 and action is 'I' then insert record and column values accordingly

  s ' there is, then update the record of the place where empno = cur.empno and attendance_date = mydate;

• How to add data to the table using Manager POST for restful Apex application

  Hi all

  I managed to create a service application web Manager restful using GET for the Restful service module. I am able to get the data in row on the presentation of a table row id in the application. But I can't find an appropriate example, how the new data in the table can be posted or deleted. I created a POST handler for a URI scheme and look forward on how to proceed. Any help would be really appreciated.

  Source for the POST Manager:

  Also created 2 parameters id and the book.

  Check out the following tutorials OBE, that explains the creation of GET and POST RESTful Web Services and how to use them in the APEX.

  • Creation and use of RESTful Web application services Express 4.2
  • Creation and use of RESTful Web application services Express 5.0

  Also what yo mean "looking forward on how to proceed? Do you want to or created for use/consume in your Oracle APEX application hosted RESTful web services?

  If Yes, in your Application, you must create a RESTful Web Service reference -> shared components. Then, create a form/report based on Web Service reference.

  Of course, you'll want to change the types of data, etc. as needed.

  I assumed that the XML can contain several "" sections and that each section can contain several entries.

  Thus the XMLTABLE aliasing as 'x' gives information of XML, and supplies the data associated with the XMLTABLE with alias 'y' which gets the multiple authors, which itself section of the XMLTABLE with alias 'z' for each of the article_item.

  CDATA stuff are handled automatically by SQLX (XML functionality integrated into Oracle's SQL)

• Update on the table by extracting the data from the table even under certain conditions

  Hi Experts,

  I have the table EMP which currently has 6 entries.

  EMP_SYS BATCH_NO JOIN_DATE LOGIN_ID STATUS FLAG

  1 FEBRUARY 10 PROD 84 Y IND123 ABC

  DEV 1-23 APRIL 98 Y IND123 ABC

  2 12 APRIL PROD 98 Y IND123 ABC

  2 2 APRIL DEV 98 Y IND123 ABC

  3 13 APRIL PROD 98 Y IND123 ABC

  3 3 APRIL DEV 98 Y IND123 ABC

  CONDITION: I need to take lines which has the minimum BATCH_NO for each of the EMP_SYS

  for example,.

  1 FEBRUARY 10 PROD 84 Y IND123 ABC

  DEV 1-23 APRIL 98 Y IND123 ABC

  For the above two lines, I need to update the status of DEF. How to select this criterion and update in the same query?

  Currently, I used the query to select the minimum BATCH_NO for each of the EMP_SYS below.

  SELECT EMP_SYS, BATCH_NO, JOIN_DATE, FLAG, LOGIN_ID, STATUS

  Of

  (

  EMP_SYS, BATCH_NO, JOIN_DATE, FLAG, LOGIN_ID, STATUS, SELECT ROW_NUMBER)

  COURSE NR (PARTITION BY ORDER OF EMP_SYS OF EMP_SYS)

  FROM EMP

  WHEN STATUS = 'ABC' AND FLAG = "Y".

  )

  WHERE

  NR = 1;

  If I try to use the update on the above query statement... It updates every 6 rows instead of 2 rows.

  Please suggest me a way to update only the two lines that has the minimum BATCH_NO for each of the EMP_SYS.

  But is possible to write the query without using the Group of?

  Update e EMP

  set STATUS = "DEF".

  where BATCH_NO = (select min (BATCH_NO) from EMP I where STATUS = 'ABC' AND FLAG = 'Y' and i.emp_sys = e.emp_sys)

• Select this OPTION to generate XML data from the table using XMLELEMENT, XMLAGG gives error ORA-19011 string buffer too small

  My select statement fails with the error:

  
  

  The ORA-19011 string buffer too small

  
  

  The select statement looks like:

  
  

  SELECT TO_CLOB)

  • It looks like I can choose only 4000 characters using the SELECT statement (please, correct me if I'm wrong)

  I'd use the XMLGEN package. But the environment team says no mounted drives in the future with the arrival of the EXADATA.

  NO HARD DRIVE MOUNTED, NO ACCESS TO THE DATABASE DIRECTORIES

  No UTL_FILE

  I need to use the REEL spool the resulting XML data of the SELECT query.

  SQL is a standard in my org, but I can do with a PL/SQL solution also to load data into a table (cannot use a COIL with PL/SQL)

  What I do is:

  1. a column of type CLOB to a xml_report of the loading of the above SELECT query table
  2. Then using SELECT * FROM xml_report to SPOOL the data to a file report.xml

  No need of XMLTYPE data behind. Xml data stream is fine for me.

  In addition, I need to validate the XML file, also using XSD.

  Problem is that the resulting lines of the select query are supposed to be from 15000 to 20000 bytes long.

  Oracle database version: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64 bit Production

  A Suggestion or a solution to this problem would be appreciated.

  It looks like I can choose only 4000 characters using the SELECT statement (please, correct me if I'm wrong)

  You use the right method.

  There is an implicit conversion from XMLType to the data type VARCHAR2 as expected by the function TO_CLOB, where the limitation, and the error.

  To serialize XMLType to CLOB, use the XMLSerialize function:

  SELECT XMLSerialize (DOCUMENT

  XMLELEMENT ("accounts",

  ...

  )

  )

  OF ANY_TABLE;

  For the rest of the requirement, I wish you good luck trying to spool the XML correctly.

  You may need to play around with the SET LONG and SET LONGCHUNKSIZE commands to operate.

  Create the trigger of the sur-insert and check the data are thre or not through the value of the primary key in this trigger. If the data is thre then update or it is then do not insert in the same trigger.

  Thank you
