APEX 4.1 - Populate DB based on right panel of shuttle

Question

APEX version: 4.1.1.00.23
Oracle 11g
I have a shuttle on a page, and when I move item(s) to the right panel from the left, I want to update a table in the database with what is in a select list.
In this case, when I select 'Analyst_1' from the drop down, it will populate the right side based on javascript.

DB table (before clicking button):
             Field                          Analyst
Co-Borrower Credit Score       Analyst_1
Appraised Value               (null)
Appraisal Identifier          (null)Then, after I move some items from the left panel to the right panel and click 'Apply Changes', I want 'Analyst_1' to be put in the analyst field on the DB for each of the field names on the right panel.

DB table (after clicking button):
            Field                        Analyst
Co-Borrower Credit Score    Analyst_1
Appraised Value             Analyst_1
Appraisal Identifier        Analyst_1Here is my code for when the button 'Apply Changes' is clicked.
UPDATE data_table
   SET analyst_name = :P51_ANALYST
WHERE field IN (SELECT a_field
                   FROM
                     xmltable('/root/e/text()' passing xmltype('<root><e>'
                     || REPLACE(:P51_SHUTTLE_RIGHT,':','</e><e>')
                     || '</e></root>') columns a_field VARCHAR2(50) path '/'));Edited by: Sid_244 on Nov 14, 2012 12:35 PM

Rohit -
I tried your example, but when I click the 'Apply Changes' button, the DB table removes all of the items that are associated with the analyst in the select list. So if there was anything in the right panel or items that I moved over to the right panel, the analyst is removed from their attribute.
Here is an example of what I am trying to accomplish:

Here is the code that I ran:
DECLARE
l_selected HTMLDB_APPLICATION_GLOBAL.VC_ARR2;
BEGIN
  l_selected := HTMLDB_UTIL.STRING_TO_TABLE(:P51_SHUTTLE);
  FOR i IN 1..l_selected.count
  LOOP
        UPDATE DQ_MANUAL_EDIT
          SET DQ_ANALYST = :P51_ANALYST
          WHERE DQ_ATTRIBUTE in (l_selected(i));
  END LOOP;
END;Other failed codes:
declare 
v_count number;
begin
-- First check if the
select count(*) into v_count
from DQ_MANUAL_EDIT
where dq_attribute = :P51_SHUTTLE_RIGHT
and :P51_SHUTTLE_RIGHT is not null;
if v_count > 0 then
  -- If it exists then save it
  update DQ_MANUAL_EDIT
  set DQ_ANALYST = :P51_DQ_ANALYST
  where DQ_ATTRIBUTE = :P51_SHUTTLE_RIGHT;
else
  -- Else insert a new record into the table
  insert into DQ_MANUAL_EDIT
  (DQ_ANALYST, DQ_ATTRIBUTE)
  values
  (:P51_DQ_ANALYST, :P51_SHUTTLE_RIGHT);
end if;
end;
--Test #2
declare
    tab apex_application_global.vc_arr2;
begin
    tab := apex_util.string_to_table (:P51_SHUTTLE_RIGHT);
    for i in 1..tab.count loop
        UPDATE DQ_MANUAL_EDIT
          SET DQ_ANALYST = :51_ANALYST
          WHERE DQ_ATTRIBUTE = :P51_SHUTTLE_RIGHT;
    end loop;
end;
--Test #3
declare
    tab apex_application_global.vc_arr2;
begin
    tab := apex_util.string_to_table (:P51_SHUTTLE_RIGHT);
    for i in 1..tab.count
    loop
       UPDATE DQ_MANUAL_EDIT
       SET DQ_ANALYST = :51_ANALYST
       WHERE DQ_ATTRIBUTE = tab(i);
    end loop;
end;
--Test #4
DECLARE
var_test  VARCHAR2(2000):= NULL ;
begin
SELECT a_field into var_test
                   FROM
                     xmltable('/root/e/text()' passing xmltype('<root><e>'
                     || REPLACE(:P51_SHUTTLE_RIGHT,':','</e><e>')
                     || '</e></root>') columns a_field VARCHAR2(50) path '/');
end;
