Value of htmlbd_items in variable

Question

Hello everybody,
I created an PLSQL process and there I want to put the current value of the loop into a variable, but it doesn't work. I get the error message "no data found" .
The code extract is the following:
for i in apex_application.g_f02.first..apex_application.g_f02.last loop
select stunden into v_ilp_std
from cn_pl_std_peplanung
where abt_id = '1'
and pe_id IN (select apex_application.g_f02(i) from dual)
and l_art_id IN (select apex_application.g_f03(i) from dual)
and version_id IN (select apex_application.g_f04(i) from dual)
and idee_id IN (select idee_id from cn_pl_projektidee where name = apex_application.g_f05(i));If I change the code by replacing the items with real values it works:
for i in apex_application.g_f02.first..apex_application.g_f02.last loop
select stunden into v_ilp_std
from cn_pl_std_peplanung
where abt_id = '1'
and pe_id = '2'
and l_art_id = '2'
and version_id '24'
and idee_id IN (select idee_id from cn_pl_projektidee where name = 'idea 7');Does anybody have an idea what could be the problem?

Patrick - It doesn't matter if one of those array elements is null. You will get a "no data found", however, if you reference an element that is empty, i.e., that has not been assigned a value, null or otherwise. This usually happens when you use checkboxes, but it doesn't appear that you are using any, just looking at your code. You need to add debug statements to your process and insert the counts of each array into a debug table so you know what you've got. For example:
/*create table dbg (n1 number, c1 varchar2(4000));*/
declare i number;
begin 
i :=  apex_application.g_f02.count;
insert into dbg(c1,n1) values('f02',i); 
i :=  apex_application.g_f03.count;       
insert into dbg(c1,n1) values('f03',i); 
i :=  apex_application.g_f04.count;    
insert into dbg(c1,n1) values('f04',i);
i :=  apex_application.g_f05.count;    
insert into dbg(c1,n1) values('f05',i);
commit;
end;Also, I think those subqueries are an odd way to code it. Can't you just do this?
select stunden into v_ilp_std
from cn_pl_std_peplanung
where abt_id = '1'
and pe_id = apex_application.g_f02(i)
and l_art_id = apex_application.g_f03(i)
and version_id = apex_application.g_f04(i)
and idee_id IN (select idee_id from cn_pl_projektidee where name = apex_application.g_f05(i));Scott
