Sorting without quering???

Question

Hello,
is there any way that we can sort a block by a column without executing the query again...if yes then please tell me how can i achieve this,,
I have a form based on view made on columns form three different tables having 5000 records and i have a button that sorts a particular column in ascending/descending order when pressed..
I am currently uisng the execute_query et the end of my sorting code. and is taking 8 seconds to sort the block when the button is pressed.
the block show 24 records at a time..
I just want to know if there is any way that we can sort the data without quering again as the data is already in the form..and it will not take 8 seconds..
thanks in advance
regards,

Answer 1

I do not query 5000 records on first execute query, only 24 records are
retieved when the form runs and for 24 records it is still taking 8 seconds.Then something has gone wrong. Even if the server is doing a full-table-scan to order the 5000 records, then passing the first 24 to your form, that should only take about a second.
Have you done something by mistake, like setting the block's Query All Records property to Yes, or maybe issued a Last_Record; command after the query?
And how long does a similar query take in SQL Plus? You can test it this way:
Declare
  Cursor C is
    -- this select should have the same where and order by as in your form:
    Select  col_1, colL_2, etc...
     from whatever_tables
     where ...
     order by col_A, col_B, etc... ;
  R C%rowtype;
Begin
  Open C;
  for i in 1..24 loop
    Fetch C into R;
  end loop;
  Close C;
End;
