Maximum rows to fetch in a Query Oracle Reports10

Question

Is it possible to limit the number of rows a Query returns by a line calculated i.e. instead of maximum number of rows being e.g. 3 it could be :C_CALLINES?
I tried this but I just get invalid number as an error.

Answer 1

Thanks a lot for that. Here is the before reports trigger where should I put
SRW.SET_MAXROW('Q_1',1);
Function BeforeReport return boolean is
begin
BEGIN
  -- srw.do_sql('alter session set sql_trace = true');
  select displayed_field
  into   :C_continued
  from   po_lookup_codes
  where  lookup_type = 'POXPRPOP'
  and    lookup_code = 'CONTINUED';
  select displayed_field
  into   :C_address_at_top
  from   po_lookup_codes
  where  lookup_type = 'POXPRPOP'
  and    lookup_code = 'ADDRESS AT TOP';
/* Bug 1484478
  The call to initialize is being made in after parameter value trigger and it
  is not necessary to do it here again
  SRW.USER_EXIT('FND SRWINIT');
/* Change the :P_single_po_print parameter value
to 1 if po_from and po_to parameters are same.
Then Query will fetch the correct data for all conditions and uses the
indexes incase of :P_po_num_from=:P_po_num_to and ALPHANUMERIC data

  If :P_po_num_from = :P_po_num_to THEN
            :P_single_po_print := 1;
  END IF;
  srw.user_exit('FND INSTALLATION OUTPUT_TYPE="STATUS"
                 OUTPUT_FIELD=":P_EC_STATUS"
                 APPS="EC"');
  srw.message ('010', :P_ec_status);
  SRW.USER_EXIT('FND FLEXSQL CODE           ="MSTK"
                             OUTPUT         =":P_FLEX_ITEM"
