[Solved] Reference apex_application.g_fXX in "execute immediate" statement

Question

Hi!
I created a dynamically generated tabular form - the number of columns is not known in advanced. Each cell of the form is a text item generated with apex_item.text().
I want to write an after-submit process that saves the values from the form into a database table. In this process I already know how many columns there are in the report so I want to do the following:
--for each row...
for i in 1..apex_application.g_f01.count loop
  -- and for each column in that row (number of columns is in v_col_count)
  for j in 1..v_col_count loop
    -- get the value of text item
    v_query := 'select apex_application.g_f0' || j || '(' || i || ')' || ' from dual';
    execute immediate v_query into v_value;
    -- now do some DML with v_value
  end loop;
end loop;The problem is that I get an error: ORA-06553: PLS-221: 'G_Fxx' is not a procedure or is undefined where xx is the number from the generated query.
My question is - am I doing something wrong or is is just not possible to reference apex_application.g_fxx in "execute immediate"? Will I have to manually check for all 50 possibilites of apex_application.g_fxx? Is there another way?
TIA,
Jure

Well now I know what was wrong and what you were trying to tell me - apex_application.g_fxx is not visible in "plain" SQL. And now I also have a solution to this problem. The point is to wrap the select statement with begin - end block so that the statement is rendered as pl/sql:
--for each row...
for i in 1..apex_application.g_f01.count loop
  -- and for each column in that row (number of columns is in v_col_count)
  for j in 1..v_col_count loop
    -- get the value of text item
    v_query := 'begin select apex_application.g_f0' || j || '(:i)' || ' into :x from dual; end;';
    execute immediate v_query using i, out v_value;
    -- now do some DML with v_value
  end loop;
end loop;This works great :).
