• apex_item.select_list_from_query in PL/SQL?

  Hello
  
  I use APEX 4.0 on a 10g database.
  
  I need to use the apex_item.select_list_from_query function in a PL/SQL program.
  

  variable varchar2(1000);
  SELECT apex_item.select_list_from_query(1,sel_name,'SELECT sel_name FROM user_selection WHERE id = (SELECT id FROM users WHERE upper(login)=upper(:APP_USER))','style="width:100%;margin-bottom:5px;"','YES','%',' ',null,'label') INTO variable FROM user_selection;
  htp.p(variable);

  Who works only the query returns many rows:

  ORA-01422: exact fetch returns more than requested number of rows

  If I add a where condition to not return clause that one line, it works.
  If I use a cursor, then I loop through the records, it works but I get several drop-down lists.
  
  Can someone tell me how to use this function in PL/SQL?
  
  Thank you.
  
  Yann.

  This is the current or default value. If an existing value of the database is necessary, then there must be a clause where clause to limit the extraction of a line, as you mentioned, for example

  declare
    l_sel_name varchar2(30);
  begin
    SELECT sel_name INTO l_sel_name FROM user_selection WHERE ...
    htp.p(
      apex_item.select_list_from_query(
          1
        , l_sel_name
        , 'SELECT sel_name FROM user_selection WHERE id = (SELECT id FROM users WHERE upper(login)=upper(:APP_USER))'
        , 'style=""'
        , 'YES'
        , '%'
        , ' '
        , null
        , 'label'));
  end;
  

• Column Collection reference in APEX_ITEM.select_list_from_query

  I'm now making reference to a column in my collection in the APEX_ITEM.select_list_from_query function. Below, you can see where I tried this, but I get just an error. Any help would be greatly appreciated, thank you.

  APEX_ITEM.select_list_from_query (9, c005,'SELECT WORKLOAD_INDICATOR, wi.) APEX_DATA WORKLOAD_INDICATOR_ID. NURSE_STAFF_WORKLOAD_INDICATOR wi JOIN APEX_DATA. NURSE_STAFF_INDICATORS_WEIGHT w ON wi. WORKLOAD_INDICATOR_ID = w.WORKLOAD_INDICATOR_ID WHERE DEPT_ID = V ("P1_DEPARTMENT") AND (assets = "Y" GOLD wi.) WORKLOAD_INDICATOR_ID = ' | C005. ) GROUP OF WORKLOAD_INDICATOR, wi. Order WORKLOAD_INDICATOR_ID of sum (w.weight) DESC', NULL, 'YES', NULL, 'Select a workload indicator')

  What value there c005? If it is empty, then this might explain the error.

  If this call to apex_item is part of a larger selection, then show the selection complete. Since you concatenate c005 value in the string without any assertion there are chances of surprising characters, like whites.

  Maybe you need to encapsulate a case this whole thing all about expression in order to eliminate cases where c005 has no correct value.

  As

  cases where c005 is null or no regexp_like (c005, "\D") then

  APEX_ITEM.select_list_from_query (9, c005,'SELECT WORKLOAD_INDICATOR, wi.) APEX_DATA WORKLOAD_INDICATOR_ID. NURSE_STAFF_WORKLOAD_INDICATOR wi JOIN APEX_DATA. NURSE_STAFF_INDICATORS_WEIGHT w ON wi. WORKLOAD_INDICATOR_ID = w.WORKLOAD_INDICATOR_ID WHERE DEPT_ID = V ("P1_DEPARTMENT") AND (assets = "Y" GOLD wi.) WORKLOAD_INDICATOR_ID = ' | C005. ) GROUP OF WORKLOAD_INDICATOR, wi. Order WORKLOAD_INDICATOR_ID of sum (w.weight) DESC', NULL, 'YES', NULL, 'Select a workload indicator')

• Arithmetic applied to a variable

  I'm just back in Captivate development and here is something that I used to know how to do that I have a hard time to recreate. The interaction is simple, the learner suggested a number in a text box, click on submit and the number is multiplied by a static number, and the result is displayed. So far, here's what I can do:

  I can create a variable and the number in the input text box appears on the screen. I can also create a standard action that uses the variable and do the math. I can't find a way for the output to the screen with a click of the submit text box button. Ideas, links, or other suggestions?

  Yes, that's the answer... In the action of the text entry area, I configured: success: run advanced measures then Script: Total who has worked like a champ... Thanks for the comments!

• How do you define a default value for APEX_ITEM. SELECT_LIST_FROM_QUERY?

  Hi all
  I have the report based on a query
  
  SELECT distinct apex_item.hidden (1, seq_id), c003 c004, c006, APEX_ITEM c005. SELECT_LIST_FROM_QUERY (6, c020, 'select DISTRIBUTION_NAME, DISTRIBUTION_NAME from the DISTRIBUTIONS',' style = "" ',' YES, ' default here? "," ", null, 'label'") 'BONOU,"NVL (c017, 'SPLIT'), 'Split', SEQ_ID
  OF APEX_collections
  WHERE collection_name = "ARGYLL_INVOICES."
  order of seq_id
  
  
  I would like to enter a default value in the APEX_ITEM. SELECT_LIST_FROM_QUERY. I can't make it work.
  
  Anyone know what I am doing wrong, or suggest an easier way?
  Thank you

  Just as a note, but you want to ensure your APEX_ITEM call is closed. The code snippet you posted isn't complete.

   APEX_ITEM.SELECT_LIST_FROM_QUERY(6,c020, 'select DISTRIBUTION_NAME, DISTRIBUTION_NAME from DISTRIBUTIONS','style="", SEQ_ID   <-- No closing )
  

  In literature - http://www.utoug.org/i/doc/api099.htm - (even if it is not necessarily the easiest to read), he gives this explanation of the syntax:

  APEX_ITEM. () SELECT_LIST_FROM_QUERY
  p_idx in NUMBERS
  p_value IN VARCHAR2 default,
  p_query IN VARCHAR2,
  p_attributes IN VARCHAR2 default,
  p_show_null IN VARCHAR2 default,
  p_null_value IN VARCHAR2 default,
  p_null_text IN VARCHAR2 default,
  p_item_id IN VARCHAR2 default,
  p_item_label IN VARCHAR2 default,
  p_show_extra IN VARCHAR2 DEFAULT)
  RETURN VARCHAR2;

  What you want to watch is p_value to set an initial value. It must come from your data, but you might want to consider doing a NVL or DECODE to replace your default.

  In this case, it would change your query to be:

  SELECT distinct apex_item.hidden(1, seq_id), c003,c004,c005, c006,
        APEX_ITEM.SELECT_LIST_FROM_QUERY(6,c020, 'select DISTRIBUTION_NAME, DISTRIBUTION_NAME from DISTRIBUTIONS','style=""),
        SEQ_ID
    FROM APEX_collections
   WHERE collection_name = 'ARGYLL_INVOICES'
  order by seq_id 
  

  If the value is always NULL, you can use the p_show_null, p_null_value and p_null_text to highlight 'by default'

  SELECT distinct apex_item.hidden(1, seq_id), c003,c004,c005, c006,
        APEX_ITEM.SELECT_LIST_FROM_QUERY(6,NVL(c020,0), 'select DISTRIBUTION_NAME, DISTRIBUTION_NAME from DISTRIBUTIONS','style="",YES, 100, 'Default'),
        SEQ_ID
    FROM APEX_collections
   WHERE collection_name = 'ARGYLL_INVOICES'
  order by seq_id 
  

• read into the buffer variable published network shared

  

  I use a shared variable that is published in the network buffer to write data to an RT target and read data buffered by the host application.

  I followed a different behavior regarding data buffering using Variable vs reading read the shared Variable node.

  There is no problem the shared variable node read but using the results of reading variable function of loss of data, such as access without alkaline reserve. I can read only some of my data values.

  I see no difference in access in the buffer in LV2009 help.

  against

  Any help is appreciated

  Christian

  Hi Christian,

  The behavior you describe is because the client side PSP buffering is not applied to the Variable API shared in LabVIEW 2009.  It was a design decision, but eventually, we hope to include this feature in a future version of LabVIEW.  This bug here as you pointed out is the lack of documentation for it.  Corrective Action Request # 202159 has been filed for this issue.

  Let me know if you need assistance working around this issue.

• By subtracting the Cp6 system variable?

  Hi all

  I shows the progress of the slide using the system variable $$cpInfoCurrentSlide$ $ $ $rdinfoSlideCount$ $

  But since I have a few slides 'ghosts' that are not actually part of the lesson (help of slides, etc.), I don't want to count them as part of the total number of slides.

  Unfortunately, Captivate is arithmetic applies to system variables (i.e. $$cpInfoCurrentSlide$ $ $$ rdinfoSlideCount$ $-3). That would make life so much easier in this case and many others.

  Anyway, I've tried (and failed) to create a new variable, assign the value of $$rdinfoSlideCount$ $ for the new variable and then subtract 3 from the new variable. Can someone explain please the right way to do this? Basically, I want to just display the value of $$rdinfoSlideCount$ $ minus 3.

  I couldn't find a close reference to what I'm looking for...

  Hello Doug,

  I agree, I wish that we could simply add expressions to variables as you suggested.

  Stem is correct on how it is done, but allow me to expand on his position.

  Steps to follow:

  1. go in project/Variables and create a new variable of user (a name that makes sense)

  2 save it (you don't need anything to other filled)

  3. go in Advanced Actions... and create a Standard Action and give it a name of Action that makes sense

  4. Add a new action, in the first column [action type] select Expression, in the columns section, select the user variable created in step 1 = variable (choose cpInfoSlideCount), select '-' and then select literal and enter the total number of slides that you do not want to remove the County.

  5. save it

  6. to view this new value, you must go to the slide and select Action: enter: perform advanced Actions and select Script (it is the name of your tip in step 3 Action

  7. Insert a text caption and add some text you need and then add select Insert Variable, which is the name chosen in step 1

  Fact.

  I hope I captured all the steps. I'm not near a computer and I'm half asleep. That's all for tonight.

  Take care of all, Shawn

• Apex_item.text dynamic item add or subtract value

  I have a report that creates dynamic items using the package apex_item, like this:
  

  select id
  ,      apex_item.hidden(1,id) 
  ,      label
  ,          decode(typ_id,
                      1, apex_item.text(p_idx=> 2, p_value=> null, p_attributes=> 'class="number"') || 'num', /*this should be a numberic field, isn't working jet*/

                      3, apex_item.select_list_from_query(p_idx=> 2, p_query=> 'select label, id from list where prop_id = ' || id, p_show_null=> 'NO'),
                      4, apex_item.date_popup(2, 0),
                      5, apex_item.text(2,'0') || '<a href="f?p=&APP_ID.:1:&SESSION."><img src="#WORKSPACE_IMAGES#add.gif"/></a> <a href="f?p=&APP_ID.:1:&SESSION."><img src="#WORKSPACE_IMAGES#substract.gif"/></a>',
                      descr
                 ) value
  from properties 
  order by id

  In the latter type of element (where typ_id is 5) I want to have a textfield allowing only numberic values. If the user clicks on the image "add.gif" the value of the element must be added by 1, and when the user clicks on 'substract.gif' value must be lowerd by 1. How can I make this work? The images can be replaced by another element, if necessary.

  Hi Mir,

  My apologies for the restructuring of the query using case. I hope this would help you. The code could be much simpler if you could take the JS logic to a JS function on the page.

• Question in presentation Variable

  Hello world
  
  I created a variable for the week and the year and I'm trying to merge them to apply as a filter.
  
  To do this, I have converted the week num in char type. The week so not 1, 2, 3.12, 13 will be displayed as 01,02, 03... 12, 13.
  so I can add concatenate them with year and together there filter for a report.
  
  Reason for all this is. I need to display the results to a report based on the selection of values prompt like
  
  of the year of the week for the week year
  2010 50 2011 05
  
  Fact table and calendar are joined by the date fields.
  
  When the prompt values are selected and applied to the variable of presentation rather than spend '05' it's just by the way of "5". How to get this done. Are also tell me the work around to filter with cookers.
  
  I hope that I am clear,
  
  Thanks in advance
  
  Concerning
  Sandeep

  Hello

  I tried in my environment and syntax '2011' | right ("0" |) Cast (50 as CHARACTER (2)), 2) works very well.

  You can try with the integer data type:

  Cast ((2011*100+PRESENTATION_VARIABLE) as char (6)).

  Well, not directly. However, if the function returns SQL declared of type you could:

  Hello:

  What exactly are you trying to do? It seems to me that you are trying to redirect to the same page that defines the list select using the apex_item API. To pass a value in the URL of the target for the value, I think that must be a page/app APEX element.
