ORA - 00935, Group function nested to deep

Hi
Suggestions on ho to go round such errors, or if is it any configuration in the database that may be changed.
Extended a view with some lines to aggregate som amounts.
The lines included is as follows:
Sum(Decode(InStr(Upper(rca.lcdescription),'VAL1'),0,0,Nvl(rca.lnprice,0)),
Sum(Decode(InStr(Upper(rca.lcdescription),'VAL2'),0,0,Nvl(rca.lnprice,0)),
Then the ORA - 00935 occured.
The full select looked something like:
SELECT
mg.lcid,
mg.lcdescription,
ro.lcfkestateid,
me.lcestatename,
ro.lcfkbuildid,

Stein,
Is it possible to put the sum(decode statements into another table with the keys you need to join? Then create a view using the newly created sum values table?

Thanks in advance.

well,
first you want to group,
then you want to order,
and most probably then you are interested in the N top records.
I had a try on table USER_OBJECTS to make things easier:
select * from
(select
object_type
,status
,nvl(oi ,0) oi
,nvl(doi,0) doi
from
( select
object_type
,status
,sum(object_id) oi
,sum(data_object_id) doi
from
user_objects
where
created between sysdate -1000 and sysdate
group by
object_type
,status
) A
order by
oi desc
) B
where rownum < 5
;

ORA-00935: group function is nested too deeply - SQL Query is correct...

select s.sname, to_char(sum(t.amount), 'fm$999999.00')
from transactions t, salespeople s
where t.sid = s.sid
group by s.sname, t.year
having (t.year = 1997) and max(sum(t.amount));
I'm trying to print sales person name who had the highest total sell in 1997. I do not see where did i go wrong in the above query...Isn't nested group function allowed?!
What about this?
select s.sname, to_char(sum(t.amount), 'fm$999999.00') as "TOTAL"
from transactions t, salespeople s
where t.sid = s.sid
group by s.sname, t.year
having (t.year = 1997) and sum(t.amount) = (select max(amount) from transactions where year = 1997);
It should return something, but it does not due lack of data in database. I think the above code is correct. I just need to confirm from you...

select s.sname, (case when sum(t.amount) > sum(t2.amount)
then sum(t.amount)
else sum(t2.amount)
end) "TOTAL"
from transactions t, salespeople s
where t.sid = s.sid
group by s.sname, t.year
having t.year = 1997
union
select s.sname, sum(t2.amount)
from transactions t2, salespeople s
where t2.sid = s.sid
group by s.sname, t2.year
having t2.year = 1997;
Your code looks good, but it does not work in Oracle Developer...
The above should work isn't it? The inner query gets executed then the outer one so the result i get in

ORA-00934: group function is not allowed here

Hi,
My requirement is to check oi.quantity is equal to sum of packing_detail. quantity
by order_number
select oi.quantity_ordered oi_qu, pd.quantity pq
from ordered_items oi, packing_details pd
where oi.ordered_item_id = pd.ordered_item_id
and oi.quantity_ordered = sum(pd.quantity)
and oi.order_number = '29';
after executing above query I get error
SQL Error: ORA-00934: group function is not allowed here
00934. 00000 - "group function is not allowed here"
Please tell me how to resolve it.
Thanks in advance
Sandy

You have to make use of a subquery;
select oi.quantity_ordered oi_qu, pd.quantity pq
from ordered_items oi, packing_details pd
where oi.ordered_item_id = pd.ordered_item_id
and oi.quantity_ordered = *(select sum(pd.quantity) from packing_details pd1 group by pd1.ordered_item_id)*
and oi.order_number = '29'; This is based on the assumption that ordered_items is the summarize data and packing_details are the line item level data.

PL/SQL equivalent of T-SQL - "group function is not allowed here"

Hi all, hope someone can give me a hand as I'm pretty stuck! I have been trying to convert some MS SQL Server T-SQL statements into Oracle PL/SQL and am stuck on the below one:
SELECT
CA.AssessmentID,
(SELECT ProductName + ISNULL(' - ' + PrincipalBenefit,'')
FROM rptPolicySnapshot WHERE PolicyID = MAX(CA.PolicyID)
AND SnapshotID = 1),
MAX(CA.PolicyID)
FROM rptClaimInvoiceLineSnapshot CIL
INNER JOIN rptClaimAssessmentSnapshot CA
ON CIL.AssessmentID = CA.AssessmentID
AND CIL.SnapshotID = CA.SnapshotID
WHERE CIL.SnapshotID = 1
GROUP BY CA.AssessmentID
This works fine in MSSQL but returns the below error in Oracle:
'ORA-00934: group function is not allowed here'
If I take out the subquery the query works fine.
Any ideas as to the syntax? I am new to Oracle so not sure as to how I should go about writing this.
Thanks in advance!
Leo

Getting Group Function is not Allowed

Hello All....
When I run the following in the SQL command screen it works fine... But when I try to use it in APEX to populate page values, it gives me the error...
ERROR
1 error has occurred
ORA-06550: line 25, column 74: PL/SQL: ORA-00934: group function is not allowed here ORA-06550: line 24, column 1: PL/SQL: SQL Statement ignored
CODE THAT WORKS IN SQL COMMAND SCREEN
SELECT
SUM(CASE WHEN SLOT = 'Q' THEN '1' ELSE '0' END) AS C_SLOT,
SUM(CASE WHEN TEST = 'P' THEN '1' ELSE '0' END) AS C_TEST,
FROM TBL_REC;
CODE THAT GIVES ERROR ON APPLICATION EXPRESS PAGE

SUM(CASE WHEN TEST = 'P' THEN '1' ELSE '0' END) INTO :P2_C_TEST,

The colums SLOT and TEST have letter codes, I just want it to count just when it matches a certain letter. In the SQL Command Screen, it is returning one row, with the counts, everything is fine. It is only a problem when I try to use it anywere on a page in Application Express.
The full version has about 20 lines that are all sum lines, but I can not even get the 2 line ver above to work.
Any thoughts?

This will work .. the into clause goes after the select columns ... into var1 ,var2 etc ..

Nested Group Function without Group By Problem

Hey everyone,
I have 3 tables as below:
TABLES
ITEM (Item_no, Item_price, desc)
DeliveryItem (delivery_no, item_no, quantity)
Delivery (delivery_no, delivery_date)
SELECT desc, MAX(SUM(quantity)) FROM DeliveryItem, Item, Delivery WHERE Item.item_no = DeliveryItem.item_no AND Delivery.delivery_no = deliveryitem.delivery_no;
And I'm trying to output description of most delivered item but I got an error like SQL Error: ORA-00978: nested group function without GROUP BY. Could you help me to fix my code?
Thanx

Hi,
DESC is not a good column name; you could get errors if the parser thinks it means DESCending. I used DESCRIPTION instead, below.
I think the best way is to do the SUM in a sub-query, lkike this:
WITH     got_r_num     AS
     SELECT       item_no
     ,       SUM (quantity)     AS total_quantity
     ,       RANK () OVER (ORDER BY SUM (quantity) DESC)     AS r_num
     FROM       deliveryitem
     GROUP BY item_no
SELECT     i.description
,     r.total_quantity
FROM     got_r_num     r
JOIN     item          i     ON     r.item_no     = i.item_no
WHERE     r.r_num     = 1
;If you want to do it without a sub-query:
SELECT       MIN (i.description) KEEP (DENSE_RANK LAST ORDER BY SUM (di.quantity)
                    AS description
,       MAX (SUM (quantity))     AS total_quantity
FROM       deliveryitem     di
JOIN       item          i     ON     d1.item_no     = i.tiem_no
GROUP BY i.description
;If you do nested aggegate functions, then every column in the SELECT clause must be an aggregate applied to either
(a) another aggregate, or
(b) one of the GROUP BY expressions.
That's why you got the ORA-00937 error.
This second approach will only display one row of output, so If there is a tie for the item with the greatest total_quantity, only one description will be shown. The RANK method will show all items that had the highest total_quantity.
It looks like the delivery table plays no role in this problem, but it there's some reason for including it, you can join it tpo either query above.
Of course, unless you post test copies of your tables (CREATE TABLE and INSERT statements) I cn't test anything.

ORA-00978 without group function

I've experienced a strange problem with oracle 11g.
I've retrieved the oracle exception ORA-00978 even if there was no group function in my query.
I supposed was a problem in the optimizer so I rebuild the tables statistics, after that the query was execute successfully.
Does anyone has an idea what the problem is?
Is possible that a bug exists in the 11g optimizer?
My oracle version is:
Oracle Database 11g Enterprise Edition 11.1.0.6.0 64bit Production
the query i tried is:
SELECT *
FROM TBCALENDAR Cal,
VWCALENDARACTIVITY CA,
VWSE R,
TBSCHEDULERPARTITION P,
TBREGION REG,
TBRESOURCE RES ,
TBZIPCITY z
WHERE Res.id=Cal.RESOURCE_ID
AND R.RESOURCE_ID=RES.ID
AND Cal.ACTIVITY_ID=CA.ID
AND CA.SCHEDULING=1
AND Cal.SCHEDPARTITION_ID IN
(select item.PARTITION_ID
from tbidcprofile prof,
tbidcpartitem part,
tbschedpartitem item
where prof.USERPROFILE_ID=4
and prof.IDCPARTITION_ID=part.PARTITION_ID
and part.BUSINESSUNIT_ID=item.BUSINESSUNIT_ID
and part.REGION_ID=item.REGION_ID )

AND P.ID=Cal.SCHEDPARTITION_ID
AND REG.ID(+)=Cal.WORKREGION_ID
AND Z.GEOLOCATION_ID(+)=Cal.HOMEGEOLOC_ID;
VWCALENDARACTIVITY and VWSE are two views, but I can select from them without any problem.
I've also tried to remove one view at a time an the error occurs only when the query uses both view at the same time.
Thanks

How to display single row column with nested group function

SQL> select deptno, Max(sum(sal)) SalSum
2 from emp
3 group by deptno;
select deptno, Max(sum(sal)) SalSum
ERROR at line 1:
ORA-00937: not a single-group group function
Can you please the Help me to get the Max(sum(sal)) with Deptno ......

select deptno, sum(sal) SalSum
from emp
group by deptno;The ablove query will give only one value for SALSUM for a department. So there is no meaning on applying MAX on this for a department..
What are you trying to achieve?
This?
select max(salsum) salsm,max(deptno) keep(dense_rank first order by salsum desc) deptno
from(
select deptno, sum(sal) SalSum
from emp
group by deptno);Edited by: jeneesh on Sep 4, 2012 6:00 PM
