• 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')

• Apply to a variable to APEX_ITEM. SELECT_LIST_FROM_QUERY

  OS = Windows 7 version

  Version of DB = 10G

  Apex Version = 3.2.1.00.11

  Hello

  Currently, I'm trying to use apex_item.

  I want the order of the SELECT_LIST_FROM_QUERY to display the users at the top of the drop folder.

  I created a view named dbv_team_list;

  select upper (parties.last) || ' ' || upper(parties.first) || ' - ' || skill.skill_level || ' - ' || team_list.status display
       , team_list.team_list_id return
    from dbx_team_list team_list
       , dbx_users users
       , sfm_common.sct_parties parties
       , dbx_skill_level skill
       , dbx_pay_rate pay_rate
  where team_list.user_id = users.user_id
     and users.par_id = parties.par_id
     and team_list.skill_level_id = skill.skill_level_id
     and team_list.pay_rate_id = pay_rate.pay_rate_id
     and team_list.effective_to is null;
  
  
  
  

  I want to use the query named dbv_team_list like this and add an order by (to obtain the registration of the user logged on to appear at the top of the list);

  select display, return from dbv_team_list order by (case return when 3 then 0 else 1 end) asc
  
  
  
  

  I formed what follows as a test to see if I need work and it does.

  SELECT APEX_ITEM.SELECT_LIST_FROM_QUERY(12,NULL,'select display, return from dbv_team_list order by (case return when 3 then 0 else 1 end) asc') "Name"
    FROM DUAL
  
  
  
  
  
  

  I created something called P19_USERNAME to store the value of the column in the view named «BACK» This value is a number.

  But when I try to put a variable in the code it returns an error. The following text shows what I tried so far and everyone here is the error code returned.

  Example 1

  SELECT APEX_ITEM.SELECT_LIST_FROM_QUERY(12,NULL,'select display, return from dbv_team_list order by (case return when :P19_USERNAME then 0 else 1 end) asc') "Name"
    FROM DUAL
  
  
  
  
  
  

  error report:

  PL/SQL: ORA-00932: inconsistent data types: expected NUMBER obtained TANK

  ORA-06550: line 1, column 7:

    FROM DUAL
  
  

  Failed to parse the SQL query:

  Could someone tell me if this is possible and how would I make the code so it's works.

  APEX are "you typed": all element values are of type VARCHAR2. The SQL CASE expression requires that the original expression and comparison expressions are of the same type. Here, the original expression seems to be a NUMBER, or the comparison of the expressions must also show NUMBERS. The APEX P19_USERNAME element is a VARCHAR2, so it must be explicitly converted or accessible using the function NV:

  
  

  SELECT APEX_ITEM.SELECT_LIST_FROM_QUERY(12,NULL,'select display, return from dbv_team_list order by (case return when to_number(:P19_USERNAME) then 0 else 1 end) asc') "Name"
    FROM DUAL
  

  
  

  Example 2

  1. SELECT APEX_ITEM. SELECT_LIST_FROM_QUERY (12, NULL, "Select display, return of the order of dbv_team_list (case back when NV('P19_USERNAME') then 0 1 other end) CSA") 'name '.
  2. OF THE DOUBLE

  Failed to parse the SQL query:

  ORA-00907: lack of right parenthesis

  Quotes inside strings must be escaped by doubling them:

  SELECT APEX_ITEM.SELECT_LIST_FROM_QUERY(12,NULL,'select display, return from dbv_team_list order by (case return when NV(''P19_USERNAME'') then 0 else 1 end) asc') "Name"
    FROM DUAL;
  

  However, the best approach when dealing with strings containing code is to use the alternative quoting mechanism:

  SELECT APEX_ITEM.SELECT_LIST_FROM_QUERY(12,NULL,q'{select display, return from dbv_team_list order by (case return when NV('P19_USERNAME') then 0 else 1 end) asc}') "Name"
    FROM DUAL;
  

  Also suggest you use does not RETURN as a means of identification as it is a keyword in PL/SQL.

  Try to remove all except one of the calls apex_item.select_list_from_query, and then rewrite this one to use subquery factoring. Now compare at the same time for the same query with and without subquery factoring. In addition, 500 lines is a realistic number that you expect someone to change?

• 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

• Apex_item.text dynamic item add or subtract value

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

  ,      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*/

  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.

• ID of the game with SELECT_LIST_FROM_QUERY

  Hello
  
  I use ApEx 4.0 on Oracle 10 g.
  
  I created a ListBox using SELECT_LIST_FROM_QUERY:
  

  apex_item.select_list_from_query(1,v_loggus_name,'SELECT loggus_name FROM USER_SELECTION WHERE loggu_id ='||v_loggu_id,'style="width:100%;margin-bottom:5px;"','NO','P3_CART_LIST','label');

  In the documentation , we read: "ID attribute for the < input > tag HTML p_item_id.".
  
  But a selection list is a < select > tag, not a < input > tag...
  
  If the ID is not set when you look at the HTML code.
  
  I tried to use instead:
  

  apex_item.select_list_from_query(1,v_loggus_name,'SELECT loggus_name FROM USER_SELECTION WHERE loggu_id ='||v_loggu_id,'id="P3_CART_LIST" style="width:100%;margin-bottom:5px;"','NO',null,'label');

  But it doesn't work when I try to call an ajax like this (use my application process: P3_CART_LIST):
  

  var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=Add_to_cart',0);
  get.add('P3_CART_LIST','a_value');

  = > ERR-1002 cannot find the item for the "P3_CART_LIST" element ID "349 enforcement.
  
  Any idea?
  
  Thank you.

  Can you help me solve this problem?
  Thank you!

  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.

• Feature Select multi with apex_item type

  I need implement the feature selection multi for the report. Is this can be implemented with the apex.item.

  For a line, you can do something like this:

  Select ename, empno, apex_item.select_list_from_query (1, null, 'select deptno from emp ',' multiple = "multiple" ') from emp where empno = 7839

• Problem with the cascading for interactive report selection list

  Hi all.

  I'm trying to implement the solution of cascading to the tabular presentation list.

  https://Apex.Oracle.com/pls/Apex/f?p=31517:176:103661090335568:

  But instead of the form of paintings, I use interactive report. After executing the query, I get the error:

  ORA-06550: line 1, column 147: PL/SQL: ORA-00936: lack of expression ORA-06550: line 1, column 13: PL/SQL: statement ignored

  
  

  My Sql query for the report:

  select 
  apex_item.hidden(1, a."DATA_ID")DATA_ID,
  apex_item.select_list_from_query(10,
    b.WAVE_GROUP,
   'select GROUP_DISPLAY, GROUP_RETURN from dwd_wave_group',
   'onchange="f_set_casc_sel_list_item(this,f11_'||LPAD (a.DATA_ID, 4,'0')||')"',
   'YES',
   '',
   '- Select Group -',
   'f10_' || LPAD (a.DATA_ID, 4, '0'),
    NULL,
   'NO'
   )WAVE_GROUP,
  apex_item.select_list_from_query(11, b."WAVE_USER",
  'SELECT username d, '
  ||'username r FROM dwd_user where groups = '||b."WAVE_GROUP",

  '- Select User -',
  'f11_' || LPAD (a.DATA_ID, 4, '0'),
   NULL,
  'NO'
  )WAVE_USER
  from "DWD_WAVE_MASTER" a, dwd_wave_assignment b
  where a.data_id = b.data_id
  and b.wave_id = 'wave_1'
  

  If I exclude the condition 2nd selection list query and change as below then everything works fine. Query does not give error on sql developer.

  Use: APEX 4.2.6 with Database 11g.

  apex_item.select_list_from_query(11, b."WAVE_USER",
  'SELECT username d, '
  ||'username r FROM dwd_user',
  '',
  'YES',
  '', 
  '- Select User -',
  'f11_' || LPAD (a.DATA_ID, 4, '0'),
   NULL,
  'NO'
  )
  

  Can someone please help!

  Thank you

  Hi Charles,
  Basically, there are few questions here
  First of all I don't know what causes the Oracle error
  failed to parse SQL query: ORA-01403: no data found
  
  I just rename the columns and back return that fixed the issue. I guess that the metadata of the apex was damaged for some reason any.
  There is no problem with your javascript or the application process.
  The issue has been with your application to the element Protection of Session State has been Restricted - can not be set browser and you try to set their via JavaScript which will fail, I changed it to unlimited use.
  		   

• Select the list doesn't work is not in the report - see demo

  Ok..
  
  I have created a demo on APEX 4.1.1... and 4.2 and it fails when 10 characters or more are in the list, with 103 lines or more

  You use the apex_item.select_list_from_query method which returns a VARCHAR2 value that has a maximum of 4000 bytes size when it is retrieved in a SQL query.

  Go to the apex_item.select_list_from_query_xl method returns a CLOB value up to 32 K in size, such as discussed in the error report: ORA-06502: PL/SQL: digital or value error: character string b. (The problem, it was not a not clear exactly how the list was generated).
