Using select in select in oracle report query - oracle

Question

I am creating a new report where I have only one cursor in the report and the report has no paper layout (it goes directly to a CSV format).
I have a query where I need to make a sub query something like
SELECT
grou.GROUP_ID GROUP_ID
,grou.group_name group_name
....
(((SELECT SUM(nett_instalment_invoice_amount)
FROM instalments
WHERE member_product_id = member_product_id)) subscription)
FROM
....
and so on....
While compiling report I encounter an error saying
Encountered Symbol SELECT while expecting one of the following symbols:
( + -
can this be helped without adding a group by clause at the end?
As I tried an alternative approach by putting in a group by clause and directly using sum function instead of select (sum()).
Please urgent help needed.
Thanks.

Answer 1

there is a simple workaround for this by creating a function let's call it get_installment_inv_sum with one parameter member_product_id like this:
create or replace function get_installment_inv_sum (p_member_product_id number) return number
as
v_sum number
begin
SELECT SUM(nett_instalment_invoice_amount)
into v_sum
FROM instalments
WHERE member_product_id = p_member_product_id;
return v_sum;
end;
then you can call your select like:
SELECT
grou.GROUP_ID GROUP_ID
,grou.group_name group_name
....
,
get_installment_inv_sum(member_product_id) subscription
FROM ...

This is certainly allowed:
select d.dname, (sum(e.sal) from emp e where e.deptno = d.deptno) as dept_sal
from dept d;
And so is this:
select d.dname, sum(e.sal)
from dept d
left outer join emp e on e.deptno = d.deptno
group by d.dname;
So what did you do exactly?

Which version of Oracle Reports ?
The scalar subqueries syntax came in around Oracle 8/8i, but the development of Oracle reports stopped sometime around the stone-age. A lot of the enhanced SQL syntax of the last 10+ years hasn't made it in.
If you can create the bulk of the query as a view in the database, and just select from the view in the report, then you have more flexibility
