• How to develop the hierarchy column automatically when NDRs by one

  Hi Experts,
  In 11.1.1.6.0, how OBIEE to widen the column hierarchy automatically when NDRs by agent?
  For example:
  SampleLite DPR, when we drag 'Hierarchy Time' and the Sales column in the report and he sent by the agent, it will show only sales 'Total', don't show any value level, such as Year, Month, Day.So how the hierarchy column automatically expand when NDRs by agent?
  
  If we are expanding at all levels and keep it, he will be allowed, however, when we add new data, it will automatically be collpased and does display no data at the lowest level, forcing the users or developers to modify this report for the expansion of the hierarchy. We think it's very wrong, is there a good suggestion or the method to reach our requirement?

  Hello

  In the lower pane, goto step selection-> select the hierarchy column in the list->, click on 'Step then new'-> 'Select members based on a hierarchy'-> in the drop-down next to the Action menu: add members of-> select all levels. This will expand the hierarchy to the selected level.

• How the first column heading must be repeated if the table breaks across pages

  Hi Experts,

  RTF model, header row in the table automatically repeat if record go to the next page. in similar fasion, I want to repeat the first column heading, table breaks on any page.

  Please help reslove this issue...

  Hello

  You can add the tag to the first column and the first row of the table. It will repeat 1st column when table to break across pages.

  Here 1 means, repeat first column when table to break across pages.

  I hope this will solve your problem.

  P.S. If you provide 2, this means, repeat for column 2 of the table through the pages

  Please check the issue as resolved, if that answers your question. Thank you

• How better to insert a subarray (line) in a 2D array to the correct index which is based on the value of the first column

  Hello

  I would like to insert a subarray (line) in a 2D to the correct index table. The position is to say the index value depends on the value of the first column of the table 2d.

  As an examlple my 2d array would look like this

  230 50 215 255

  300 60 270 330

  360 20 350 370

  And I would like to insert another line (subarray) with the following values

  320 40 300 340

  This new line should be placed between the second and third rows (this is based on the first column only).

  I tried the threshold 1 d function table by taking an 1Dsub array of my 2d array (first column), then using the first of the new line (320) as the threshold. It sort of work, but it does not work when I start the table (IE there is only 1 row) and it seems to not work properly on other occasions (as explained in the help of Labview).

  Hopefully the explanation is clear enough for any suggestion. Thanks in advance for the help!

  The idea is I have start with a new table and add these lines in the right order every time that the user sets the values Jack

  Ahh, so try this.

  This will also work with an empty array.

  You want to do with this function it is a Subvi.

  Make the entries 'table' and 'subarray"on the connector, then 'new array' output.

  You can then put this Subvi in a loop with a registry to shift and it will help to add new lines in a sorted order, when they are added.

  That is what you were aiming for?

• How remove the line by line by comparing to the first column?

  Hello!
  
  I have a problem - I need to remove the line by line, but the problem is, I know that the first COLUMN of the table is a PK.
  To retrieve the NAME of the COLUMN that I use:
  
  SELECT column_name, table_name FROM USER_TAB_COLUMNS WHERE column_id = 1 and table_name = c1.tmp_table_name;
  But it does not somehow.
  Below you can see my script (which has not worked for now):
  
  declare
  XXX varchar2 (100);
  Start
  C1 in (select table_name, tmp_tables tmp_table_name) loop
  IMMEDIATE EXECUTION
  ' SELECT column_name in ' | xxx | "USER_TAB_COLUMNS WHERE column_id = 1 AND table_name = ' |" ' || C1.tmp_table_name | " ' ;
  immediate execution
  "start."
  for c2 in (select * from ' | c1.tmp_table_name | start loop ')
  Insert into ' | C1.table_name | "values c2; delete from ' | C1.tmp_table_name | 'where ' | xxx |' = c2.' | xxx |'; exception: when other then null; end; end loop; end;';
  end loop;
  end;
  
  P.S. The Inserts work perfect. I have a problem with deleting lines that are in c1.table_name, of c1.tmp_table_name (the two tables have the same structure, PK, always), because I have the names of columns different another tables which are PK. (for example: K, ID, NS and so on) Please help me to write the correct script.
  For example this will be for the first line recovered as:
  Start
  C1 in (select table_name, tmp_tables tmp_table_name) loop
  immediate execution
  «Start for c2 in (select * from ' |)» C1.tmp_table_name | Start loop ')
  Insert into ' | C1.table_name | "values c2; delete from ' | C1.tmp_table_name: ' where K = c2. K; exception: when other then null; end; end loop; end;';
  end loop;
  end;
  This script works perfectly. But I have many other tables with different PK - K No.

• Read the data in the first column selected in a multicolumn listbox

  When a line is selected in a ListBox multicolumn (1 point), how can I go on reading the data in the first column?

  

  The listbox multicolumn itself is the digital picture data type. If you have allowed only 1 point selection and selection mode select any row, it returns the line number. The property node 'Element names' to return a table 2d-chains of the elements in your Inbox. The index of the row to the value of the listbox and column 0. See code attached.

• How to read the two columns of data from the Port series

  Hello

  I'm reading two columns of data from the serial port.

  Example:

  52439 52430

  52440 52437

  52209 52214

  51065 51070

  52206 52390

  Thank you for your help.

  The analysis of string function takes a "Format string" on top (with the right button of the function and choose Help, which explains all the entries).  In particular, you can say 'Give me two numbers separated by a tab' and the output will be two numbers (whole or floating, depending on the chosen format).  In particular, %d\t%d specifies a decimal integer, , whole decimal.

  How can I get the counts for each parent in a single query
  
  Published by: user7955917 on August 24, 2012 07:26

  Generic function how you want the query to be.

  If the structure is known in advance, as in your example a 'books' and then a 'library' root element, it's as simple as:

  SQL> select x1.parent_id, x2.child_name, count(*)
    2  from tmp_xml t
    3     , xmltable(
    4         '/books/bookstore'
    5         passing t.object_value
    6         columns parent_id   for ordinality
    7               , child_list  xmltype path '*'
    8       ) x1
    9     , xmltable(
   10         '/*'
   11         passing x1.child_list
   12         columns child_name varchar2(30) path 'name()'
   13       ) x2
   14  group by x1.parent_id, x2.child_name
   15  order by x1.parent_id, x2.child_name
   16  ;
  
   PARENT_ID CHILD_NAME                       COUNT(*)
  ---------- ------------------------------ ----------
           1 book1                                   2
           1 book2                                   1
           1 book4                                   1

           2 bookn_1                                 1
           2 book1                                   1

  10 rows selected
   
  

  If you want a generic solution that works without knowledge of the structure, you will need a recursive approach, and most importantly, you should know which nodes in distinct, I suppose that the leafs?

  Also, please help if you can provide the link of reference on the function name() years what are the other expression, that I can use after the path

  You can start reading the documentation: http://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb_xquery.htm#CBAGCBGJ
