Delimited String To A Single Row Within A Table

Question

I'll try to make a simple example of what I am trying to accomplish...
Let's say that I have a table (Blah) which has the following Fields:
User, DateTime, Q1, Q2.... all the way to Q50.  The Questions are radios with a value of 1,0, or null.
Since I didn't want to manually make 50 different items for the Radio questions, I am creating them from Javascript within a Region Source; as well as giving them id's and names.  This worked fine.
When I hit a submit button, I have Javascript create a delimited string for the questions, which I pass to a Shared Item.  (1,0,1,1,null,0,etc...)  I then have the Javascript run a Shared Procedure for the Insert into my Table.
Here is where I am stuck.  I am confused on how to merge the delimited string into my Insert statement, from PL/SQL.
Here is a dummied down sample of what I am trying to write.  (Shared Item is :ITEM_ARRAY, with a delimiter of ~:~ )
DECLARE
    array APEX_APPLICATION_GLOBAL.VC_ARR2
BEGIN
    array := APEX_UTIL.STRING_TO_TABLE(:ITEM_ARRAY, ':~:' );
    INSERT INTO tbl_blah (
        :APP_USER
        ,SYSDATE
         FOR z IN 1..array.count LOOP
             array(z);
         END LOOP;
END;
Every which way I tried, I always get Not Enough Values Error.
I tried to make everything in a delimited string as well:
Insert Into tbl_blah (SELECT * FROM array)
Can someone please enlighten me on the correct way to do this.  All of the examples I have seen are to write to multiple rows, via the loop.  I want to just have 1 record, horizontally.
Thanks !!!

Hi,
Why can't you insert a row into table with first two columns and do update for that row???
Just for simple work around, I have created a table with below columns,
USER_NAME VARCHAR2 
EXAM_DATE DATE
M1 NUMBER
M2 NUMBER
M3 NUMBER
M4 NUMBER
M5 NUMBER
M6 NUMBER
M7 NUMBER
M8 NUMBER
M9 NUMBER
M10 NUMBER
I wrote a below code to insert a row into that table,
declare
v_arr APEX_APPLICATION_GLOBAL.VC_ARR2;
v_stmt varchar2(1000);
begin
v_arr:= APEX_UTIL.STRING_TO_TABLE(:p_all_items,'~');
insert into test_group(user_name,exam_date) values (:APP_USER,sysdate);
dbms_output.put_line('row inserted');
FOR i IN 1..v_arr.COUNT LOOP
dbms_output.put_line('i='||i||' value='||v_arr(i));
if v_arr(i) is null then
v_stmt:='update test_group set m'||i||'=NULL';
else
v_stmt:='update test_group set m'||i||'='||v_arr(i);
end if;
dbms_output.put_line(v_stmt);
execute immediate v_stmt;
END loop;
end;
I just ran this block in 'SQL Commands', It worked for me. but i inserted only one row, so it updates a single row, In case of multiple row need to use the unique column for update. change the above code as per your requirement.
I hope this work around will help you. If not can you please create an example in apex.oracle.com and share login credentials.
Thanks
