在oracle报表查询中的选择中使用选择

我正在创建一个新的报告，其中报告中只有一个光标，并且报告没有纸张布局，它直接转换为CSV格式

我有一个查询，我需要做一个子查询，比如

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

在编写报告时，我遇到一个错误，即

Encountered Symbol SELECT while expecting one of the following symbols:
(  +  - 

如果不在末尾添加GROUPBY子句，这是否有帮助

因为我尝试了另一种方法，加入一个GROUPBY子句，直接使用sum函数而不是SELECTSUM

如有需要，请提供紧急帮助

谢谢。

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;

这也是：

select d.dname, sum(e.sal)
from dept d
left outer join emp e on e.deptno = d.deptno
group by d.dname;

那么您到底做了什么？

标量子查询语法是在Oracle 8/8i前后出现的，但Oracle报表的开发在石器时代的某个时候停止了。在过去的10多年中，许多增强的SQL语法都没有得到应用

---

如果您可以在数据库中创建大部分查询作为视图，并且只需从报表中的视图中进行选择，那么您就有了更大的灵活性

通过创建一个函数，我们将其称为get\u installation\u inv\u sum，其中有一个参数member\u product\u id，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;

然后您可以调用您的选择，如：

SELECT
         grou.GROUP_ID                            GROUP_ID
         ,grou.group_name                          group_name
         ....
         ,
         get_installment_inv_sum(member_product_id) subscription
FROM ...

这个问题非常模糊。请显示实际的SQL和实际的错误消息。这应该添加到问题中，而不是作为答案给出。运行时会发生什么？它在plsql编辑器中运行平稳，但在oracle报告中添加到编译时，它会给出错误
