我正在创建一个新报告，报告中只有一个光标，报告没有纸张布局（直接转换为CSV格式）。
我有一个查询，我需要进行类似
的子查询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
.... 等等....
编译报告时遇到错误
Encountered Symbol SELECT while expecting one of the following symbols:
( + -
这可以在不添加group by子句的情况下得到帮助吗？
当我通过放入group by子句并直接使用sum函数而不是select（sum（））来尝试替代方法时。
请急需帮助。
感谢。

有一个简单的解决方法，通过创建一个函数让我们用一个参数member_product_id称它为get_installment_inv_sum，如下所示：
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;
然后你可以调用你的选择：
SELECT
grou.GROUP_ID GROUP_ID
,grou.group_name group_name
....
,
get_installment_inv_sum(member_product_id) subscription
FROM ...

这当然是允许的：
select d.dname, (sum(e.sal) from emp e where e.deptno = d.deptno) as dept_sal
from dept d;
这就是：
select d.dname, sum(e.sal)
from dept d
left outer join emp e on e.deptno = d.deptno
group by d.dname;
那你到底做了什么？

哪个版本的Oracle报告？
标量子查询的语法出现在Oracle 8 / 8i中，但Oracle报告的开发在石器时代的某个时候停止了。过去10多年来，许多增强的SQL语法都没有成功。
如果您可以将大部分查询创建为数据库中的视图，只需从报表中的视图中进行选择，那么您就可以获得更大的灵活性
