'Group by' over CURSOR

Question

hi!
i have a problem with grouping over a CURSOR.
when i execute the following statement, i get the following error 'not a single-group group function'.
how can i manage to group over the CURSOR? or is the problem elsewhere?
i cant do sth. like 'group by TALIAS2.id' because i cant adress TALIAS2.id.
would be very glad for advise.
cheers!
SELECT SUM(TALIAS1.price),
CURSOR(
SELECT TALIAS2.id AS ID
FROM dual TALIAS2
) AS CUR_BESTELLUNGEN
FROM table1 TALIAS1

Answer 1

you don't need a cursor statement for the example that you've given. Maybe you simplified it too much?
One solution can be a simple join:
SELECT SUM(TALIAS1.price), TALIAS2.id AS ID
FROM table1 TALIAS1
CROSS JOIN dual TALIAS2
group by TALIAS2.id This code of cause does not make any sense at all. As a starter: Dual does not have a column id. And since it has only one row, you would need get different groups. So please give a more reasonable example.
