  Chambers,

  You can use wwv_flow_utilities.array_element to avoid any no_data_found. The function does not raise any errors. For example, for the line which only have a value of table when you wait 2, it can be useful.

  EXECUTE IMMEDIATE 'insert into table_name@Schema1 (col1,col2)
      values (:1,:2)'
      USING
        wwv_flow_utilities.array_element(v_data_array,1),
        wwv_flow_utilities.array_element(v_data_array,2);

• Get "no data found" when I download the report

  Hai...
  
  In my application, I created a region of reports where the data are displayed... I gave 'Download' format csv... when I try to download, I could not the data in the spreadsheet "excel" his coming as no data found...

  Hi David,

  I've always found preferable to set the value of the element on a page using a calculation when I want him to have a starting value that does not rely on a database column.

  On your two fields, set the static allocation Type of Source and remove source.

  Now, on your page, click on the button create (icon +) in the section of the Page rendering calculations. Then enter the following settings:

  Geographical area: item on this page
  Point calculation: select your P1_STARTDATE
  Calculation Point: Before header
  Calculation type: SQL query
  Calculation: Select TO_CHAR(SYSDATE-1,'MM/DD/YYYY') from Dual
  Condition Type: Article 1 of the Expression value is NULL
  Expression 1: P1_STARTDATE

  Repeat this for your usng P1_ENDDATE Select TO_CHAR(SYSDATE,'MM/DD/YYYY') from Dual to the query

  Now, when the page is loaded first, the calculation conditions are checked. As the two fields are empty, the calculations are made and items get their start values. Your application should then work ok for export.

• How to get the query of the region "PL/SQL function body returns the query string"?

  Hello
  
  is it possible to get the query string from the region of type "PL/SQL function body returns the query string"?
  
  I can get the definition of the region as a PL/SQL procedure, but I am interested in the returned query. I tried to write something like
  
  < pre > v_return_query: = «...» » ;
  : P49_QUERY: = v_return_query;
  Return v_return_query; < / pre >
  
  to save the return on hidden item P49_QUERY string, but it does not work. I get the error message: ERR-1002 cannot find the item for the "P49_QUERY" element ID in the application '4000 '.
  
  Kind regards
  Przemek

  If you need to make reference to a page element in the block then you can use this type of control to avoid having to use generic column names:

  if apex_application.get_current_flow_sgid(:APP_ID) = apex_application.get_sgid then-- runtime  :P9_SQL := vSQL;else-- design time  null;end if;
  

  But if all you want to do is capture the SQL debugging you can take all the references element in the block and use the insert statement (in a debug table) as I showed earlier.

• Bills of the AP - query gives output in the editor, but no data found when run from a workflow

  Hello

  I am working on a custom workflow related to invoices from the AP and I came across this very odd situation where the below query works perfectly well by operating in any PL/SQL as Toad/SQL Developer editor but when run in an Oracle Workflow custom, the query raises an exception NO_DATA_FOUND.

  I set debugging instructions to capture the values of the parameters (lv_invoice_id and lv_hold_id being retrieved workflow attributes) before and after the SELECT statement and noticed that the values of the parameters are set correctly.

  SELECT type

  IN lv_match_type

  DE ap_invoices_all aia , ap_invoice_lines_all Arnaud , ap_holds_all aha

  OÙ ail . invoice_id = lv_invoice_id

  ET line_type_lookup_code = "ITEM"

  ET AIA . invoice_id = garlic . invoice_id

  ET AHA . invoice_id = AIA . invoice_id

  ET AHA . hold_id = lv_hold_id

  ET ROWNUM = 1 ;

  Can anyone suggest what could be wrong with that? Having spent 2 days trying to debug this but without success.

  Any help would be greatly appreciated.

  I added a function of the WorkflowTimeout JOB just before function which becomes the flag Match, and it worked. It appears like the workflow engine is somehow unable to assign values to the query. Putting a WAIT, he probably gave the workflow a second to assign variables with values. Seems very strange, but seems to have solved the problem. Do thorough tests to confirm that it does not break something else. Mike - appreciate all your help with this post until now. You were very prompt in answering my questions. Appreciate it.

• SQL query for the region of the tree

  Hello

  I was wondering if someone is able to help me work on a SQL query, to format the data in the table required in a part of the tree... I've never used a tree and I'm fighting to get the right data (if possible).

  The data in the table looks like this:

  

  I want to put it in a tree, using level 1 level6 with a final layout that would look like this:

  

  As you can see, the data are formatted in level6 down in the tree, but are filled in the table from level 1. Not all of the columns will be filled, so level2 for anyone 4 (France) is the equivalent of level in the tree like level6 to person 1 (Spain).

  This is Apex 4.2.5

  Oracle 11.2.0.3.0

  Sample data:

  CREATE TABLE employees
     ( employee VARCHAR2(100),
       level1 VARCHAR2(100),
       level2 VARCHAR2(100),
       level3 VARCHAR2(100),
       level4 VARCHAR2(100),
       level5 VARCHAR2(100),
       level6 VARCHAR2(100)   
     );
  
  INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person1','Team One','Recruitment','Human Resources','Fictituous Company','Murcia','Spain');
  INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person2','Team Four','Testing','IT','Big Corporate','Hanover','Germany');
  INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person3','Big Corporate','Hanover','Germany', null, null, null);
  INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person4','Brittany','France', null, null, null, null);
  INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person5','Team Three','Testing','IT','Big Corporate','Hanover','Germany');
  INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person6','Public Relations','Government Agency','Brittany','France', null, null);
  
  

  Added example given.

  Hello

  Apex-user wrote:

  Thanks Frank, this is a good example, I can work with that! Your assumptions are correct.

  A question I came, however, is that I have a data segment that comes across poorly formatted so to speak... where only the lower levels (1-2, etc.) have been filled from the bottom up.

  An example of this data would be:

  1. INSERT INTO employees (employee, level 1, 2, level3, level4, level5, level6) VALUES ('Person7', 'One Team', 'Test', null, null, null, null);

  As you can see that if you rerun the select, the test team is now duplicated, both at the level of the root in the tree as it should.

  You are not sure if the sql can be adjusted to account for this, or if it's too hard?

  It is obviously a question of data and I am trying to solve this separately (extracted data from another system out of my control).

  Thank you!

  Sorry, I'm confused.

  You say that my assumptions were correct.  What includes supported that "If test ' occurs under 'IT' in a row, then the extent of the 'Testing' occurs, it must be under"IT "?  Right after you say that assumptions are correct, you give an example where 'Testing' occurs under 'IT' to a single line, but it is not less 'IT' to another line and where is 'One Team' under 'Testing' in a line, but is 'One Team' under 'Recruitment' in another row.

  When a situation like this occurs, how you cope?  Whenever you have a problem, please post the exact results you want from the given sample data, and an explanation of how you get these results.  If you don't know about what would be the ideal results, or if you are flexible on the exact results, then at least give an example and explain your reasons.

  Maybe you want to change the got_parent of subquery like this:

  WITH unpivoted_data AS

  (

  SELECT *.

  Employees

  UNPIVOT (node_name

  FOR lvl (level1 AS 1

  level2 AS 2

  level3 AS 3

  level4 AS 4

  level5 AS 5

  level6 AS-6

  )

  )

  )

  got_parent AS

  (

  SELECT c.node_name

  MIN (p.node_name) AS a parent

  Of unpivoted_data c

  LEFT OUTER JOIN unpivoted_data p ON p.employee = c.employee

  AND p.lvl = c.lvl + 1

  GROUP BY c.node_name

  )

  SELECT LPAD (' ' ')

  2 * (LEVEL - 1)

  ) || Node_name AS entity

  OF got_parent

  START WITH parent IS NULL

  Parent = node_name PRIOR CONNECTION

  ;

  In this way, if 'Test' is current 'IT' in one line, but not under what in another line, whether under would consider the 'IT' request and not to be a root.  If 'One Team' sudden 'Testing' in a line, but under "Recruitment" in another line, it will be (arbitrarily) consider it under "recruitment".

• Positioning in the region drop-down data?

  I use DW CS3 on mac.  I have a drop down box in the left sidebar, containing vignettes, these are links to different pages that show the enlargements of the thumbs and some details about the elements to the right of the main content.  The reason for this provision is to allow the thumbs to the left that will take the sidebar, contain the size of the page and most importantly keep the enlargement and the adjacent info inches.  It works very well the problem is that when you scroll through the list of thumbs and select one new page that resets the scroll bar upward to lose viewers place in the list, and defeat the purpose of the scroll bar.  The viewer must then scroll down and select the following thumb, which in turn forces them to scroll again to find the next inch. Question is it possible to index the thumb list and load the scroll bar position, as he was to the last page, or preset position of the list in the pages below in the list? If you're confused, you can see at http://www.thunderbirdtrading.ca/apparelLadiesItem-86.html the top four links are connected as it's the last, now scroll the list to the guy and click on the link it brings you to this page and resets the list losing your place

• No data found apex 4.0

  I created an application on the site of apex oracle with the workspace that you gave me, it worked fine. I made an app to export and tried to import into my work apex 4.0, the same version that the
  site of the Oracle, she imported ok without error
  but when I opened the form, one of the regions said no data found, I have the same exact tables

  Its pretty difficult to see the source of the problem on our side.
  

• You use some type of context based view
  
• Tables/views to fine grain Access Control (Policies)
  
• Your reference to the table is correct? Perhaps a synonym is pointing to the wrong schema.
  
• atBind name of the Variable used in a query wrong/space between / had some special characters in the name, which have been lost-out/in replaced import?

  Start with the database and check the DB table/view/object used in the form.
  Add a new item on process/page that uses the same query and see if its actually import some kind of question. Or try to recreate the same form again manually in the same page and see if that retrieves data when the other is not, at the same time.

• Assigning a page element in the region of the "body of function return PLSQL SQL query.

  I've not been here in a long time. I like the new forum text editor!
  
  I have a search page in my application that contains a return region of query SQL PLSQL function body. I use PLSQL to build a query based on the user entries in various page numbers (search text, serial number, year, etc.). Using PLSQL is very useful to enforce the page quickly because there are 1/2 million lines with a lot of text fields some of which are CLOB.
  
  Users want to know how many rows were returned, but if I allow using a paging system that includes the total performance dies because ApEx has to sort through all the pages of output. Instead, I use ' line varies X to Y "without the part of" Z", and it's pretty fast. I can't use the #TOTAL_ROWS # because it does not work with this system of pagination.
  
  So, I built a code within the region of function body PLSQL to build a second query that counts only the lines based on the input parameters. I can do this query within the region using EXECUTE IMMEDIATE and the number to an output variable. The disconnect is that I can not then assign it to a page element. If I add a statement assigned to a page element, either by
  
  : P45_COUNT: = p_count;
  or
  APEX_UTIL. SET_SESSION_STATE ('P45_COUNT', p_count);
  
  then when I submit the changes I get
  
  ERR-1002 unable to find point item ID 'P45_COUNT' in the application '4000 '.
  
  as if the ApEx is not looking for the item in my application, but in the application development environment. I am able to write the results to a table and then recover data in the next region. That's how I got around the problem, but it seems too complicated and unnecessary.
  
  I wrote the following code just to illustrate the problem.
  
  Make sense? Any ideas?
  
  Thank you!

  Could you please help me where I am wrong.

  Thank you very much.

  You get this error because the element 2 has been removed and in the loop, you are iterating over all the elements from 1 to 3.

  To avoid this, use the type of loop below:

  l_index: = names_in. FIRST;

  While (l_index IS NOT NULL)

  LOOP

  DBMS_OUTPUT. PUT_LINE

  (names_in (l_index));

  l_index: = names_in. NEXT

  (l_index);

• Interactive report: "no data found" when first loading

  Hello
  
  I use APEX 4.0 with Oracle 10 g r2 under Windows XP Pro SP3.
  
  I have an interactive report and a menu with a few items to filter the report.
  
  The problem is that the first time I load the page, the report shows "no data found", when I reboot, it works. If I navigate to another page and then I go back to the page of report, it also works.
  
  There seems to be a problem with session state, but I can't found how do works, even using an AJAX setItemInSessionState() function.
  
  The query depends on the values of the elements:
  

  select
       SPAT_ID, SPAT_ACCL_NAME, SPAT_AREA_NAME, SPAT_CLASS, SPAT_NUMBER, SPAT_PT, SPAT_TYPE, SPAT_STATUS,
       round(SPAT_CUMUL,2) as "SPAT_CUMUL"

  I've implemented on apex.oracle.com, if you find the time to take a look: http://apex.oracle.com/pls/apex/f?p=4550:1
