Selectall checkbox not selecting rows in all pages

Question

Hi guys,
Please help
what is the best way to select all the pages when i click on select all checkbox in the first page. Currently my code is selecting only 1st page of rows.
Please help me.
I have region with sql query(pl/sql function body returning sql query) with the following code. Repot is conditional.
DECLARE
    l_query          VARCHAR2(32676);
BEGIN
    l_query := q'!  SELECT DISTINCT

Answer 1

Selecting all rows will never work if you have more than one page. Instead of that, you could set some kind of a flag item to a value if the select all checkbox is checked (set it to null if unchecked). If this flag is selected, your process expecting that should go over the whole resultset and process it.
