Get value from APEX_ITEM.SELECT_LIST_FROM_QUERY - column on a report.

Question

Hello.
Help. Help. Help.
I have to get value from APEX_ITEM.SELECT_LIST_FROM_QUERY - column on a report.
SELECT DISTINCT ROLE AS GET_ROLE,
JOB AS GET_JOB,
APEX_ITEM.SELECT_LIST_FROM_QUERY
( 1, '%', 'SELECT DISTINCT CODE c,
MODE m
FROM T2
WHERE ROLE = ' || ROLE ) AS GET_CODE
FROM T1
WHERE AGE >30 AND
SEX = 'M' ;
I was trying to use javascript :
for (var i = 0; i < selectlist_name.options.length; i++)
if (selectlist_name.options[ i ].selected)
result=selectlist_name.options;
But I don't know is that correct:
"selectlist_name" - APEX_ITEM.F01
(of my APEX_ITEM.SELECT_LIST_FROM_QUERY)?

Just as a note, but you want to make sure 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 the documentation - http://www.utoug.org/i/doc/api099.htm - (though it isn't necessarily the easiest to read) it gives this explanation of the syntax:
APEX_ITEM.SELECT_LIST_FROM_QUERY(
p_idx IN NUMBER,
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 look at is p_value to set an initial value. It should come from your data, but you could consider doing an NVL or DECODE to substitute your default.
In this case it would modify 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 put in a "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
