• Update of a column of table from xml data

  Hello

  I have an obligation to update a particular table from xml data column. to do this, I wrote the code below but I am not able to insert. could you please a peek into that.

  create table emp3
  as
  select *From emp
  where 1=1;
  
  alter table emp3
  add (fax_response varchar2(50));
  
  /*create sequence EmailRecords_XMLFILE_SEQ
    minvalue 1
    maxvalue 999999999999999999999999999
    start with 1
    increment by 1
    nocache;*/
  
  /* create global temporary table EmailRecords_XMLFILE
    (
    ID NUMBER not null,
    xmlfile CLOB
    )
    on commit preserve rows;*/

    (
    id NUMBER not null,
  
    response VARCHAR2(500)
  
    )

  Someone suggest me a slightly easier way to insert data...

  Thank you...

  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 input XML code?

  -What is the version of db?

• Why I can't create indexes on the table of RDF data

  When I tried to create indexes on the table of RDF data, it always say the table or view does not exist. I created the RDF model using java codes:

  Oracle Oracle = new Oracle ("jdbc:oracle:thin:@localhost:1521:orcl", "system", "123");

  Chart GraphOracleSem = new GraphOracleSem (oracle, "test2");

  
  

  And used the following commands in sqlplus to create indexes:

  SQL >

  SELECT THE SEPARATE OWNER, OBJECT_NAME

  FROM DBA_OBJECTS

  WHERE TYPE_OBJET = 'TABLE '.

  4. AND OBJECT_NAME like ' % TEST2;

  OWNER

  --------------------------------------------------------------------------------

  OBJECT_NAME

  --------------------------------------------------------------------------------

  SYSTEM

  TEST2_NS

  SYSTEM

  RDFB_TEST2

  SYSTEM

  TEST2_TPL

  OWNER

  --------------------------------------------------------------------------------

  OBJECT_NAME

  --------------------------------------------------------------------------------

  SYSTEM

  RDFC_TEST2

  
  

  SQL > connect as sysdba

  Enter the password:

  Connected.

  SQL >

  SQL >

  SQL > select * from TEST2_TPL;

  Select * from TEST2_TPL

  SQL > CREATE INDEX test2_sub_idx ON TEST2_TPL (triple. GET_SUBJECT());

  CREATE INDEX test2_sub_idx ON TEST2_TPL (triple. GET_SUBJECT())

  *

  ERROR on line 1:

  ORA-00942: table or view does not exist

  Hi Shifu,

  It is not recommended to use the SYS or SYSTEM to store/manage schema graph RDF data.

  Can you please try the following in a SQL * more terminal?

  SQL > conn system/eu1

  Connected.

  SQL >

  SQL >

  SQL > create user graphuser identified by graphuser;

  Created by the user.

  SQL > grant connect, resources, unlimited tablespace to graphuser;

  Grant succeeded.

  SQL > conn graphuser/graphuser

  Connected.

  SQL > create table graph_tpl (triple sdo_rdf_triple_s) compress;

  Table created.

  SQL > sem_apis.create_sem_model exec ('graphic', 'graph_tpl', 'three');

  PL/SQL procedure successfully completed.

  SQL > insert into graph_tpl values (sdo_rdf_triple_s ('graph', '', '', ''));

  1 line of creation.

  SQL > select count (1) in the mdsys.rdfm_graph;

  You see the same result?

• export data from the table in xml files

  Hello
  
  This thread to get your opinion on how export data tables in a file xml containing the data and another (xsd) that contains a structure of the table.
  For example, I have a datamart with 3 dimensions and a fact table. The idea is to have an xml file with data from the fact table, a file xsd with the structure of the fact table, an xml file that contains the data of the 3 dimensions and an xsd file that contains the definition of all the 3 dimensions. So a xml file fact table, a single file xml combining all of the dimension, the fact table in the file a xsd and an xsd file combining all of the dimension.
  
  I never have an idea on how to do it, but I would like to have for your advise on how you would.
  
  Thank you in advance.

  You are more or less in the same situation as me, I guess, about the "ORA-01426 digital infinity. I tried to export through UTL_FILE, content of the relational table with 998 columns. You get very quickly in this case in these ORA-errors, even if you work with solutions CLOB, while trying to concatinate the column into a CSV string data. Oracle has the nasty habbit in some of its packages / code to "assume" intelligent solutions and converts data types implicitly temporarily while trying to concatinate these data in the column to 1 string.

  The second part in the Kingdom of PL/SQL, it is he's trying to put everything in a buffer, which has a maximum of 65 k or 32 k, so break things up. In the end I just solved it via see all as a BLOB and writing to file as such. I'm guessing that the ORA-error is related to these problems of conversion/datatype buffer / implicit in the official packages of Oracle DBMS.

  Fun here is that this table 998 column came from XML source (aka "how SOA can make things very complicated and non-performing"). I have now 2 different solutions 'write data to CSV' in my packages, I use this situation to 998 column (but no idea if ever I get this performance, for example, using table collections in this scenario will explode the PGA in this case). The only solution that would work in my case is a better physical design of the environment, but currently I wonder not, engaged, as an architect so do not have a position to impose it.

• Using the procedure to display the table of multiple data

  Hi, I need help for the procedure in oracle

  I want to create the procedure to display the table of multiples with sample plan

  with a parameter imployee_id to display an employee_id, name, function, start_date, end_date

  IAM using this query to select more than one table

  SELECT e.employee_id, e.first_name, j.job_title, h.start_date, h.end_date

  E EMPLOYEES

  JOIN j jobs

  ON j.job_id = e.job_id

  JOIN the job_history:

  ON h.employee_id = e.employee_id

  WHERE e.employee_id = 200;

  Thanks for the help

  Blu and Billy showed you the 'real' solution. You can display the data returned by a cursor ref in SQL Developer, too:

  http://www.thatjeffsmith.com/archive/2011/12/SQL-Developer-tip-viewing-refcursor-output/

  Yet as a duty for a beginner is generally do not have the expected solution. Usually, teachers want to see you using a LOOP and dbms_output. something like

  DECLARE

  Xy CURSOR IS

  SELECT whatever

  As much as;

  BEGIN

  FOR r IN xy LOOP

  dbms_output.put_line (r.col1 |' # ' | r.col2);

  END LOOP;

  END;

  Of course this suggestion will inaugurate a discussion abusing DBMS output but I keep my position that it is authorized to use it for learning the basics.

• Index rebuild required after truncate the table and load data

  Hello
  
  
  I have a situation that we truncate tables bit and then we loaded data [only content] on these tables. What you need to rebuild the index online is necessary or not?
  
  
  And another question is if we drop a few clues is the total amount of space is released or not. And re-create indexes will use the same amount of space. As I don't have disk space more? In this situation, rebuild the index online will be a better idea...
  
  Can you please on this...
  
  
  truncate the table some the few loading tables + reconstruction markings online is the best (or) droping little tables, a few tables loading + re-create the index is better
  
  Can you suggest the best way... We have a time that it currently we don't have enough space on the disk... [Option should not effect the space]

  user13095767 wrote:
  Ok. I have it...

  u want to say if we disbale the index while loading... Next, we need to spend the time to build.

  If the indexes are enabled, then rebuild again is not necessary after loading tables...

  Please answer if my understanding is correct...

  above is correct

  >

  If so, how abt the differences in the space occupied by the spaces of storage during the index rebuild and re-create... T he acquires more space if recreate us [deletion and creation] or rebuild online is preferable to an index...?

  space used is the same for all options.

• How the filter E4x Xml data in a tile list?

  Hello!

  I am trying to use a search box for some xml data that I have in a tile list. Can someone point me in the right direction?

  }

  I changed the variable names to make it a little clearer. Now whenever you perform a search it will only show according to Yes (Yes). You can have nested If more more complex application but remember there is always need to be a return to true or false for each record (item).

• Script for the use of XML data to pre file form open using the player

  I need to pre fill five fields when the user opens the form using Acrobat Reader (title, name, address, etc.). The values are saved in an xml data file in the same directory as the form (no database or web services connections). I tested the xml code and form structures using shapes-> manage form data-> import data and everything works fine. Now, I need to emulate this behavior programmatically, so it does not work using only Acrobat Reader. I can't find the magic java script command to import the data (I tried xfa.host.importData and xfa.datasets.data.loadXML without result). Require purchase Pro or Livecycle Server product is not an option. This seems to be a basic requirement, so I hope I'm just being stupid and missing of which is obvious. Thank you.

• Problems with the display of XML data

  I'm a bit new to Flash and have problems out XML data in Flash. Basically, when I saw publication, all data load XML file and displays very well. But when I actually publish the file and view in a browser, no data is displayed.
  
  Data from XML is happening in the areas of dynamic text (title, description, image).
  
  I use an absolute URL to retrieve the XML data, and I tried a lot of text integrated solutions, and nothing has worked. Here, any help would be greatly appreciated.
  
  I have attached the script action, but also a piece of the XML file I get the data.

  After going through each difficulty as possible, I could find, I managed to miss the information contained in the link below. This fixed my issue.

• Select the name of the table and some data in the same sql

  If anyone can help with this?
  
  I need the name of the selection table that have columns called col1 (which could be done with the help of dba_tab_columns) and col1 data itself.
  
  Here is my desired outcome:
  
  table_name col1
  
  alex tab1
  tab2 bob
  .... ....
  Tabn sue
  
  TIA.

  You can use a cross join, like this...

  SELECT ut.table_name
  x.column_name
  OF some_table_name x
  ut user_tables
  WHERE ut.table_name = upper ('some_table_name');

  or...

  SELECT ut.table_name
  x.column_name
  OF some_table_name x CROSS JOIN user_tables ut
  WHERE ut.table_name = upper ('some_table_name');

  This will work if you have one or more column value returns. Basically, a table name is multiplied by the number of lines found in the table. I hope this helps.

• How to recover the server response XML data

  Hey fellows,

  So I wrote this piece of code that sends an image to a server (thanks a lot Mantaker for the position you where has written on it!) and then I expect to receive a response in the form of XML code. I tried to use getResponseMessage(), which gives me a nice 'OK '.

  How could I achieve this? I read somewhere that it might be possible through a feed, could you help me?

  I'll give you a lot of congratulations!

  If you already have the basics of an HttpConnection down, it gets a little easier later.

  Once you have the your HttpConnection InputStream you can create a Document for analysis using the built-in XML parser.

  public static Document getXmlDoc(InputStream in)
  {
      Document doc = null;
      DocumentBuilderFactory docBuilderFactory
          = DocumentBuilderFactory.newInstance();
  
      DocumentBuilder docBuilder;
  
      try {
          docBuilder = docBuilderFactory.newDocumentBuilder();
          docBuilder.isValidating();
  
          doc = docBuilder.parse(in);
          doc.getDocumentElement().normalize();
      } catch (Exception e) {
          System.out.println("getXmlDoc Error: " + e);
      }
  
      return doc;
  }
  

  It is a basic function that I use to read a XML from a web server. If there are errors reading or parsing of the document, this function returns null.

  After making sure that you close your InputStream, you can start reading your document.
