Hello,

I am trying to run a report from form. The forms has checkboxes. I assign a value to the checkbox when it is checked. What I would want to do is when the checkbox is checked, the value in the checkbox should go into the where clause of the SQL statement. I have many checkboxes. So all those which are checked should go into the where clause of the query.
For e.g. if I have ten diseases, I can check more than one disease. The SQL statement should be like:
select patients from patients_table where disease in (disease1, disease2, etc.). disease1, disease2, etc. are the checkboxes checked. I want to pull out the patient details in a Report.

I could pull out the details if only one checkbox is checked. Can anyone tell me how I should do if multiple checkboxes are checked?

Thank You for your help.
Rama.

In the form check each checkbox for whether it is checked or not.

for eg: The checkboxes are named d1..d10. They have a value Y if checked.

Declare
temp varchar2(2000);
begin

if :control.d1 = 'Y' then
if temp is null then
temp := :control.d1;
else
temp := temp ||','||:control.d1;
end if;
end if;

if :control.d2 = 'Y' then
if temp is null then
temp := :control.d1;
else
temp := temp ||','||:control.d2;
end if;
end if;
......
......

if :control.d10 = 'Y' then
if temp is null then
temp := :control.d1;
else
temp := temp ||','||:control.d10;
end if;
end if;

temp := 'where disease in ('||temp||')';

-- send this temp as a parameter to the report
end;

In the report:
create a parameter named temp of varchar2(2000)

Query:
select patients from patients_table||:temp;

Thank You Shilpa. It worked when I checked more than one checkbox and was able to query with the values checked in the checkbox in the where clause.
