Answer 1

Trent,
Thanks for you suggestions. .. Let me explain my problem a little better ...
I have a report that lists fields associated with a report ... I have a delete icon which deletes a row and removes it from the underlying table ... however, I am trying to implement a Before header process which runs a pl/sql process that checks if the selected field is the last field in the report ... if so, I want a confirmation dialog to pop up ... if they click cancel .. then the deletion is aborted, else the field is deleted (which triggers other status changes).
Based on this logic if there is a way to implement this based on your suggestion I would appreciate it ...
Here is the process I was trying to use .... but the I have a few issues with this approach
declare
-- cursor to check if this is the last field
cursor fld_cnt is
select count(*) from prm_ptnr_rpt_fields
where report_uid = :P22_REPORT_UID;
num_flds number;
msg varchar2(300);
begin
open fld_cnt;
fetch fld_cnt into num_flds;
If num_flds > 1 then
delete from prm_ptnr_rpt_fields
where report_uid = :P22_REPORT_UID
and field_user_key = :P9_DELETED_FLD;
commit;
:P9_DELETED_FLD := NULL;
msg := :P9_FIELD_NAME || ' Field Excluded From Report' ;
apex_application.g_print_success_message := msg;
else
htp.p('<script type="text/javascript">');
htp.p('
var r=confirm("This is the last field included in this report .. \n Deleting it will Inactivate the report and remove it from schedule (if scheduled) ...\n Do you want to proceed?");
if (r==true)
{      delete from prm_ptnr_rpt_fields 
where report_uid = :P22_REPORT_UID
and field_user_key = :P9_DELETED_FLD;
:P9_DELETED_FLD := NULL;
commit;
msg := :P9_FIELD_NAME || ' Field Excluded From Report' ;
update prm_ptnr_rpts
set report_status = 'INCOMPLETE',
active_report = 'N'
where report_uid = :P22_REPORT_UID;
msg := msg || ' and Report Status changed to INCOMPLETE';
apex_application.g_print_success_message := msg;
htp.p('}else {
alert("Delete Action Aborted");
htp.p('</script>');
End if;
Close fld_cnt;
end;
a) Even if I click cancel ... the field still gets deleted ...
b) :P9_DELETED_FLD is the id for the selected field ... I am setting it on the link attributes which places it on the URL ... I would rather user javascript (but not exactly sure how).
Thanks,
Gerald
