select et.order_id,sum(et.qty * prd.prod_cost) as order_total,listagg(prod_alias, ',') within group (order by prod_alias) as ITEMS
from ext_ol et 
join product prd on et.palias=prd.prod_alias 
where et.order_id=order_id group by et.ORDER_ID;

The above query gives me the following output:

ID TOTAL ITEMS
1 395 MC
2 440 CTF
3 460 PT,VSK
4 215 CFR
5 875 CKMT,CMT,CT
6 440 CTF
7 630 CTL

I want to add the names and prices of each of the items in a particular order_id. How can I do that?

Well, I am not sure how the new output will look like but here is what I have in mind, if its possible:

ID-----TOTAL---ITEMS-----------------PRICES-----------------NAME
1------ 395---- MC------------------- 250-------------------*list of Item names like 'ITEMS' and "PRICES"*
2------ 440---- CTF------------------ 300
3------ 460---- PT,VSK--------------- 150,180
4------ 215---- CFR------------------ 195
5------ 875---- CKMT,CMT,CT---------- 200,190,255
6------ 440---- CTF------------------ 300
7------ 630---- CTL------------------ 250

Not sure whether it can be done. If not like this then any other way? Basically I want the total, the item_name, prices of the items in the order like above.

Looks like you just need multiple listagg calls then

I have no clue how to do it. Since I need the prices and names of only those items in a particular order_id.
I can get the total in different view, and the order details in a different view but this is what I want to achieve.
is there any way I can do it without the listagg? that will also do.

Think for a minute.
you're using listagg to concatenate the prod_alias to give the item list for each order_id
The name list will be a concatenation of a different column from product. It'll need to be grouped and order in the exact same way as the item list.
Can you really not guess how to do that with a second listagg call?
After that price should be easy.

I made up some quantities and prices for your data. Would this result format be ok?

create table product (prod_alias varchar2(5), prod_name varchar2(20), prod_cost number);
insert into product values ('MC','MC desc', 395);
insert into product values ('CTF','CTF desc', 220);
insert into product values ('PT','PT desc', 100);
insert into product values ('VSK','VSK desc', 260);
insert into product values ('CFR','CFR desc', 215);
insert into product values ('CKMT','CKMT desc', 75);
insert into product values ('CMT','CMT desc', 250);
insert into product values ('CT','CT desc', 250);
insert into product values ('CTL','CTL desc', 630);

create table sales_order (order_id number, qty number, prod_alias varchar2(5));
insert into sales_order values (1,1,'MC');
insert into sales_order values (2,2,'CTF');
insert into sales_order values (3,2,'PT');
insert into sales_order values (3,1,'VSK');
insert into sales_order values (4,1,'CFR');
insert into sales_order values (5,5,'CKMT');
insert into sales_order values (5,1,'CMT');
insert into sales_order values (5,1,'CT');
insert into sales_order values (6,2,'CTF');
insert into sales_order values (7,1,'CTL');

select et.order_id,sum(et.qty * prd.prod_cost) as order_total
,listagg('[QTY '||et.qty||' '||prd.prod_name||' '||prd.prod_cost||']', ',') within group (order by prd.prod_alias) as ITEMS
from sales_order et join product prd on et.prod_alias=prd.prod_alias
group by et.ORDER_ID
order by et.order_id;

ORDER_ID ORDER_TOTAL ITEMS
1 395 [QTY 1 MC desc 395]
2 440 [QTY 2 CTF desc 220]
3 460 [QTY 2 PT desc 100],[QTY 1 VSK desc 260]
4 215 [QTY 1 CFR desc 215]
5 875 [QTY 5 CKMT desc 75],[QTY 1 CMT desc 250],[QTY 1 CT desc 250]
6 440 [QTY 2 CTF desc 220]
7 630 [QTY 1 CTL desc 630]

7 rows selected.
