Generating multiple details from a single input row

Question

Post Author: dhay

I'm using Crystal Reports Developer XI.
Each input row from the database contains a starting serial number and the number of serial numbers to be generated. The detail section of my report consists of a form containing the serial number. I want to create a form for each serial number that is to be generated. For example, if the database supplies a starting serial number of 11, and the number of serial numbers to be generated is equal to 3, my report would create three forms, the first containing serial number '11', the second form contains serial number '12', and the third, '13'. The next input row would then be read, and multiple forms would be created for that input row. And so on.
So, I want each input row to create as many instances of my report's detail section as is specified by the input field 'number of serial numbers to be generated'.
In my prior experience, each input row generates a single detail section instance on the report. Can I do what I described above in Crystal? Alternatively, is there a way to do this using SQL (possibly generating an intermediate table or view) so that the Crystal Report would receive one input row per serial number (and would thus work in the normal manner)?
Thanks in advance,

Answer 1

assume you have a check box at column no 1. and print button
create a hidden item on page zero
create a PL?SQL page process on submit - after computations and validation with condition when button press is print
and put this code
FOR i in 1..APEX_APPLICATION.G_F01.count
LOOP
if i = 1 then
:p0_invoice_selected := APEX_APPLICATION.G_F01(i);
else
:p0_invoice_selected := ::p0_invoice_selected ||','||APEX_APPLICATION.G_F01(i);
end if;
END LOOP;
create page branching to zero page and call the report on the request field
PRINT_REPORT=print_invoice and condition when button press is print
in your invoice print query put the condition
where invoice_id in (:p0_invoice_selected)
in your report template insert a group with invoice_id at the top and select page break.
Now about your page no select the section-page no not the normal page no.
but you have invoice-id as a character then i would suggest you create a type
CREATE OR REPLACE type list_table as table
of varchar2 (500);
add a function
function in_list_table( p_string in varchar2 ) return list_table
as
l_string long default p_string || ',';
l_data list_table := list_table();
l_instr number;
begin
loop
exit when l_string is null;
l_instr := instr( l_string, ',' );
l_data.extend;
l_data(l_data.count) :=
ltrim( rtrim( substr( l_string, 1, l_instr-1 ) ) );
l_string := substr( l_string, l_instr+1 );
end loop;
return l_data;
end;
and call the function in your sql query
invoice_id IN
(SELECT list.COLUMN_VALUE
FROM table(CAST (
in_list_table(:p0_invoice_selected) AS list_table
)) list))
hope this will solve your problem.
