  It's the structure of the XML where the content is changed daily and the file is placed in "D:\Test_Dir". I'm trying to load a table (teams) with the details of the team and its corresponding parent, like this project:

  proj_id team_id team_name
  001 1   Team Roger
  002 2   Team Alpha
  002 3   Team Romeo
  Below is the pl/sql block I wrote:
  
  declare
  cursor proj_cur is select project_id from projects;
  proj_rec proj_cur%rowtype;
  begin
  for proj_rec in proj_cur 
  loop
  INSERT INTO teams(team_id,team_name,project_id)
  WITH t AS (SELECT xmltype(bfilename('TEST_DIR','SCRUM.xml'), nls_charset_id('UTF8')) xmlcol FROM dual)
  SELECT  
  extractValue(value(x),'*/id')team_id
  ,extractValue(value(x),'*/name') team_name 
  ,extractValue(value(y),'/project/id') project_id
  FROM t,TABLE(XMLSequence(extract(t.xmlcol,'/scrumwise-export/data/account/projects/project'))) y
  ,TABLE(XMLSequence(extract(t.xmlcol,'/scrumwise-export/data/account/projects/project/people/teams/team'))) x 
  where (extractValue(value(y),'/project/id'))='emp_rec.project_id';
  end loop;
  end;
  
  
  This returns a cartesian product! Any help with this is much appreciated.
  

  A few additional tips BTW:

  -do not use wildcards (*) when you really know the structure of the XML document and the name of the node you want to extract.

  -use the UTF8 character set is not recommended because it supports any valid XML characters. Use rather AL32UTF8 .

  So, similar to Kim:

  select proj.project_id
       , team.team_id
       , team.team_name
  from xmltable(
         '/scrumwise-export/data/account/projects/project'
         passing xmltype(bfilename('XML_DIR','SCRUM.xml'), nls_charset_id('AL32UTF8'))
         columns
           project_id  varchar2(3) path 'id'
         , teams       xmltype     path 'people/teams/team'
        ) proj
      , xmltable(
          '/team'
          passing proj.teams
          columns
            team_id     number         path 'id'
          , team_name   varchar2(100)  path 'name'
        ) team
  where exists (
    select null
    from projects p
    where p.id = proj.project_id
  ) ;
  

  Or a shorter version using a single XMLTABLE:

  select team.project_id
       , team.team_id
       , team.team_name
  from xmltable(
         'for $i in /scrumwise-export/data/account/projects/project
            , $j in $i/people/teams/team
          return element r {
            element project_id {$i/id}
          , $j/id
          , $j/name
          }'
         passing xmltype(bfilename('XML_DIR','SCRUM.xml'), nls_charset_id('AL32UTF8'))
         columns
           project_id  varchar2(3)    path 'project_id'
         , team_id     number         path 'id'
         , team_name   varchar2(100)  path 'name'
       ) team
  where exists (
    select null
    from projects p
    where p.id = team.project_id
  ) ;
  

  And if a project can have no team, you can the outer join the XMLTABLE 2nd instead:

      , xmltable(
          '/team'
          passing proj.teams
          columns
            team_id     number         path 'id'
          , team_name   varchar2(100)  path 'name'
        ) (+) team
  

• PDF form: fill in the field with the value of another field

  Hello

  I have a PDF form that one of our employees has to be completed on a regular basis.

  There is a 'product' - text field, which is present on the form several times, which will contain the same information.

  From now on, my colleague has fill all these these one by one manually. But with the copy - paste, it doesn't take more than a few seconds.

  However, to facilitate work a little, I want to it to be able to simply fill out one of the fields (can be a specific, must not be dynamic) and all the other 'product' - fields automatically takes the value of the field of this first.

  How can I accomplish this?

  I noted the possibility of JavaScript controls.

  I am familiar with basic JavaScript, however never used it for PDF files.

  Any help and pointers would be appreciated.

  Thank you very much.

  This isn't a problem with script. Just give each field of the same name. Once the field names are the same, a change in one will be to another. For some reason that it does not work with standard HTML forms, probably the reason why you ask.

• Updated with the values in the same table, for other records corresponding to conditions

  Hi Experts,

  Sorry do not provide the structure of the table (it is a simple structure)

  I have a requirement where I need to update the columns of a table based on the same table with some match empid and date values. If the date and empid match so I have these values to any other folder and update of one who is not having details of Office . I need the Update query

  Before the update my array of values is as below

  Sort_num Emp_id Bureau start_date

  1 101 AUS 01/01/2013
  2 101 01/01/2013
  3 101 15/01/2013

  8 104 10/01/2013
  9 104 01/01/2013

  After update my table should be as below

  I don't have the time to create the table with the data, but basically, you should be able to code the following text

  update one table

  Office set = (select desktop in table b where b.emp_id = a.emp_id)

  and b.start_date = a.start_date

  and b.office is not null

  )

  where is ([as well as overall query])

  and a.office is null

  In my opinion, who will do the trick.

• update to column values (false) in a copy of the same table with the correct values

  Database is 10gr 2 - had a situation last night where someone changed inadvertently values of column on a couple of hundred thousand records with an incorrect value first thing in the morning and never let me know later in the day. My undo retention was not large enough to create a copy of the table as it was 7 hours comes back with a "insert in table_2 select * from table_1 to timestamp...» "query, so I restored the backup previous nights to another machine and it picked up at 07:00 (just before the hour, he made the change), created a dblink since the production database and created a copy of the table of the restored database.
  
  My first thought was to simply update the table of production with the correct values of the correct copy, using something like this:
  
  
  Update mnt.workorders
  Set approvalstat = (select b.approvalstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi)
  where exists (select *)
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi)
  
  It wasn't the exact syntax, but you get the idea, I wanted to put the incorrect values in x columns in the tables of production with the correct values of the copy of the table of the restored backup. Anyway, it was (or seem to) works, but I look at the process through OEM it was estimated 100 + hours with full table scans, so I killed him. I found myself just inserting (copy) the lines added to the production since the table copy by doing a select statement of the production table where < col_with_datestamp > is > = 07:00, truncate the table of production, then re insert the rows from now to correct the copy.
  
  Do a post-mortem today, I replay the scenario on the copy that I restored, trying to figure out a cleaner, a quicker way to do it, if the need arise again. I went and randomly changed some values in a column number (called "comappstat") in a copy of the table of production, and then thought that I would try the following resets the values of the correct table:
  
  Update (select a.comappstat, b.comappstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi - this is a PK column
  and a.comappstat! = b.comappstat)
  Set b.comappstat = a.comappstat
  
  Although I thought that the syntax is correct, I get an "ORA-00904: 'A'. '. ' COMAPPSTAT': invalid identifier ' to run this, I was trying to guess where the syntax was wrong here, then thought that perhaps having the subquery returns a single line would be cleaner and faster anyway, so I gave up on that and instead tried this:
  
  Update mnt.workorders_copy
  Set comappstat = (select distinct)
  a.comappstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi
  and a.comappstat! = b.comappstat)
  where a.comappstat! = b.comappstat
  and a.workordersoi = b.workordersoi
  
  The subquery executed on its own returns a single value 9, which is the correct value of the column in the table of the prod, and I want to replace the incorrect a '12' (I've updated the copy to change the value of the column comappstat to 12 everywhere where it was 9) However when I run the query again I get this error :
  
  ERROR on line 8:
  ORA-00904: "B". "" WORKORDERSOI ": invalid identifier
  
  First of all, I don't see why the update statement does not work (it's probably obvious, but I'm not)
  
  Secondly, it is the best approach for updating a column (or columns) that are incorrect, with the columns in the same table which are correct, or is there a better way?
  
  I would sooner update the table rather than delete or truncate then re insert, as it was a trigger for insert/update I had to disable it on the notice re and truncate the table unusable a demand so I was re insert.
  
  Thank you

  Hello

  First of all, after post 79, you need to know how to format your code.

  Your last request reads as follows:

  UPDATE
    mnt.workorders_copy
  SET
    comappstat =
    (
      SELECT DISTINCT
        a.comappstat
      FROM
        mnt.workorders a
      , mnt.workorders_copy b
      WHERE
        a.workordersoi    = b.workordersoi
        AND a.comappstat != b.comappstat
    )
  WHERE
    a.comappstat      != b.comappstat
    AND a.workordersoi = b.workordersoi
  

  This will not work for several reasons:
  The sub query allows you to define a and b and outside the breakets you can't refer to a or b.
  There is no link between the mnt.workorders_copy and the the update and the request of void.

  If you do this you should have something like this:

  UPDATE
    mnt.workorders     A      -- THIS IS THE TABLE YOU WANT TO UPDATE
  SET
    A.comappstat =
    (
      SELECT
        B.comappstat
      FROM
        mnt.workorders_copy B   -- THIS IS THE TABLE WITH THE CORRECT (OLD) VALUES
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    )
  WHERE
    EXISTS
    (
      SELECT
        B.comappstat
      FROM
        mnt.workorders_copy B
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    )
  

  Speed is not so good that you run the query to sub for each row in mnt.workorders
  Note it is condition in where. You need other wise, you will update the unchanged to null values.

  I wouold do it like this:

  UPDATE
    (
      SELECT
        A.workordersoi
        ,A.comappstat
        ,B.comappstat           comappstat_OLD
  
      FROM
        mnt.workorders        A      -- THIS IS THE TABLE YOU WANT TO UPDATE
        ,mnt.workorders_copy  B      -- THIS IS THE TABLE WITH THE CORRECT (OLD) VALUES
  
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    ) C
  
  SET
    C.comappstat = comappstat_OLD
  ;
  

  This way you can test the subquery first and know exectly what will be updated.
  This was not a sub query that is executed for each line preformance should be better.

  Kind regards

  Yep, use Index Array as Gerd says. Also, using the context help ( + h) and looking through the array palette will help you get an understanding of what each VI does.
  
   
  
  This is fundamental LabVIEW stuff, perhaps you'd be better spending some time going through the basics.

• It is possible to have two tables with the same name in Oracle!

  Oracle Version: 10 gr 2
  
  MS Access 2007, I had to use the 'Export' by which I copy a table (and its data) to an Oracle schema via an ODBC connection.

• How to compare the length of the data to a staging table with the definition of the base table

  Hello
  I have two tables: staging of the table and the base table.
  I get flatfiles data in the staging of the table, depending on the structure of the requirement of staging of the table and the base table (length of each column in the staging table is 25% more data dump without errors) are different for ex: If we have the city long varchar 40 column in table staging there 25 in the base table. Once data are discharged into the intermediate table that I want to compare the actual length of the data for each column in the staging table with the database table definition (data_length for each column of all_tab_columns) and if no column is different length that I need to update the corresponding line in the intermediate table which also has an indicator called err_length.
  
  so for that I use the cursor c1 is select length (a.id), length (b.SID) of staging_table;
  c2 (name varchar2) cursor is select data_length all_tab_columns where table_name = 'BASE_TABLE' and column_name = name;
  But we get atonce data in the first query while the second slider, I need to get for each column and then compare with the first?
  Can someone tell me how to get the desired results?
  
  Thank you
  Manoi.

  Hey, Marco.

  Of course, you can set src.err_length in the USING clause (where you can reference all_tab_columns) and use this value in the SET clause.
  It is:

  MERGE INTO  staging_table   dst

         WITH     got_lengths     AS
                   (

            ,     MAX (CASE WHEN column_name = 'JOB'   THEN data_length END)     AS job_len
            FROM     all_tab_columns
            WHERE     owner          = 'SCOTT'
            AND     table_name     = 'EMP'
            )
       SELECT     s.ename
       ,     s.job
       ,     CASE WHEN LENGTH (s.ename) > l.ename_len THEN 'ENAME ' END     ||
            CASE WHEN LENGTH (s.job)   > l.job_len   THEN 'JOB '   END     AS err_length

  As you can see, you have to hardcode the names of the columns common to several places. I swam () to simplify that, but I found an interesting (at least for me) alternative grouping function involving the STRAGG user_defined.
  As you can see, only the subquery USING is changed.

  MERGE INTO  staging_table   dst
  USING  (
         SELECT       s.ename
         ,       s.job
         ,       STRAGG (l.column_name)     AS err_length
         FROM       staging_table          s
         JOIN       all_tab_columns     l
        ON       l.data_length  < LENGTH ( CASE  l.column_name
                                            WHEN  'ENAME'
                                  THEN      ename
                                  WHEN  'JOB'
                                  THEN      job
                                     END
                             )
         WHERE     l.owner      = 'SCOTT'
         AND      l.table_name     = 'EMP'
         AND      l.data_type     = 'VARCHAR2'
         GROUP BY      s.ename
         ,           s.job
         )     src
  ON     (src.ename     = dst.ename)
  WHEN MATCHED THEN UPDATE
       SET     dst.err_length     = src.err_length
  ;
  

  Instead of the user-defined STRAGG (that you can copy from AskTom), you can also use the undocumented, or from Oracle 11.2, WM_CONCAT LISTAGG built-in function.
