GROUP BY: determinstic function column of group by expression 10g vs 11g
The following works in 10g but now fails in 11g.
Simple description: If I create a view of a number and subtract 2 from that number
and I group by the first column and include the 2nd column, it works in 10g and gives "not a group by column" in 11g.
It seems that 10g knew the 2nd column was derived by the first column so grouping by the 1st column gave an automatic pass to the 2nd column.
11g seems to be more strict (though I don't know why, if the 2nd column's function is purely deterministic as you would expect subtracting by 2 would be. Same is true for UPPER())
Is there a reason for this change in behaviour in 11g?
Is there some explicit reason for the change in functionality?

Hi,
Just 4 hours ago, someone else had a very similar question:
Group by fails on ORA-00979
Personally, I consider that a bug in Oracle 10. When you do a GROUP BY on a view, you can't expect the SQL engine to look at the view definition, and determine if one of the columns can be derived from another.
In practice, it's easy enough to add c1u to the GROUP BY clause, or to use MAX (c1u) instead of c1u, to make your query work.

thanks .Hi,
In a GROUP BY querry, every item in the SELECT list must be one of the following
(1) One of the GROUP BY expressions
(2) An aggregate function
(3) A constant
(4) Deterministic expressions based on the above (for example, COALESCE, where all the arguments are taken from the list above)
So if your scalar sub-query is going to be part of the GROUP BY query, it has to fit into one of those categories
I don't see any good way of convincing the compiler that your scalar sub-query is a constant, even if it happens to rturn a constant value, but you can make it either
(1) one of the GROUP BY expressions (compute it in a sub-query, to avoid repeating the whole scalar sub-query in the GROUP BY clause), or
(2) an aggregate function ( e.g. MAX ((SELECT ...))).
But the scalar sub-query doesn't have to be part of the GROUP BY query. Depending on your tables and the desired results, it might be easy to do the GROUP BY and what is now the scalar sub-query separately, and then join the two result sets.
If you need help, it always helps to post:
(1) The version of Oracle (and any other relevant software) you're using
(2) A little sample data (just enough to show what the problem is) from all the relevant tables
(3) The results you want from that data
(4) Your best attempt so far (formatted) (You posted this, but since it's unformated, it's very hard to read.)
(5) The full error message (if any), including line number
Executable SQL statements (like "CREATE TABLE AS ..." or "INSERT ..." statements) are best for (2).
Formatted tabular output is okay for (3). Type these 6 characters:
{code}
(small letters only, inside curly brackets) before and after formatted text, to preserve spacing.
Simplify the problem if you can. For example, if your real query involves many columns and many join conditions, try to post a similar problem that has few columns and very siomple join conditions, but has the same problem as your real query. -

Problems with GROUP BY - not a GROUP BY expression
Hello,
I am fighting little bit with GROUP BY expression.
After some tests I am able to reduce the problem to following...
When can I use column numbers in GROUP BY expression?
Consider this situation:
CREATE TABLE EMP4 (
NAME VARCHAR2(10)
COMMIT;
INSERT INTO EMP4 VALUES('Tamara');
INSERT INTO EMP4 VALUES('John');
INSERT INTO EMP4 VALUES('Joseph');
COMMIT;
SELECT NAME, COUNT(*)
FROM EMP4
GROUP BY 1;
00979. 00000 - "not a GROUP BY expression"
-- This is working
SELECT NAME, COUNT(*)
FROM EMP4
GROUP BY NAME;Why is the GROUP BY 1 not workig?
I am using the GROUP BY 1 because in real query there is some PL/SQL function which somehow modifies the column NAME, so I can't use the column name
SELECT TEST_PACKAGE.AppendSomeCharacter(NAME), COUNT(*)
FROM EMP4
GROUP BY 1;Of course I can nest the query and move the COUNT and GROUP BY to outer query or maybe something else, but I was just curious why is the GROUP BY not working...
Also in real query, there are 3 columns in the GROUP BY expression, so I have there GROUP BY 1, 2, 3
Thanks for helphai

Hello,
I have a query which is giving not a group by expression error even though after having all columns in group by clause,
The crazy here is the same query is working fine in three environments expect in one environment.
I did a work around on this if i use the sub query my issue is getting solved but performance is going down.
I have a union all ,collection(Multiset) clause as well. :)
Please let me know if you people have any idea/solution on this issue?
Is this related any environmental setup on oracle.?
Am using oracle 10g data base and oracle 11g for my .NET.
Thanks,
SanSFrom my experience I have got "not a group by" expression prob.
for a select satement like this:::
select tab1.id,tab1.name,count(tab2.col1)
From tab1,tab2 where tab1.id=tab2.idx
group by tab1.id,tab1.name
order by lower(name);
The prob.with order by lower(name) ....without 'lower' (any other functions) working fine...and the prob occurs when the record set called from the front end(asp.net)...directly executing from the db its working fine...

GROUP BY a.BATCH_ID
please help :( I get this error a lot of time, I dont know what I lack about the knowledge of group by functionHere are the ABC's of GROUP BY:
When you use a GROUP BY clause and/or an aggregate function, then everything in the SELECT clause must be:
(A) an <b>A</b>ggregate function,
(B) one of the "group <b>B</b>y" expressions,
(C) a <b>C</b>onstant, or
(D) something that <b>D</b>epends entirely on the above. (For example, if you "GROUP BY TRUNC(dt)", you can SELECT "TO_CHAR (TRUNC(dt), 'Mon-DD')").
In your case, the SELECT clause includes:
COUNT (a.id) which is an aggregate (A), so it's okay,
a.batch_id which is in the GROUP BY clause (B), so it's okay, and
a.associate_name which is none of the above.
"GROUP BY a.batch_id" means the otput will contain 1 row for every distinct value of a.batch_id. What if there are several rows with the same value of a.batch_id: which of the several values of a.associate_name would you want to include? If your data is such that there can only be 1 distinct value of a.associate_name for each distinct value of a.batch_id, then it doesn't matter which of them is included (they are all the same), so you can use MIN (a.associate_name) or MAX (a.associate_name), or, even better, include a.associate_name in the GROUP BY clause.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).
See the forum FAQ {message:id=9360002}
&nbps
By the way:
AND to_char(s.END_DATE,'DD-MON-YY')>'25-APR-13'
AND to_char(s.END_DATE,'DD-MON-YY')<'25-MAY-13'I don't think you really mean what you said on the 2 lines above. You porbably meant
{code
AND s.END_DATE > TO_DATE ('25-APR-2013', 'DD-Mon-YYYY')
AND s.END_DATE < TO_DATE ('25-MAY-2013', 'DD-Mon-YYYY') -
Error using group by expression
hello friends,
I use this query & used group by but oracle give error :
ORA-00979: not a GROUP BY expression
Select uu.ID,max(uu.module_name) as MainMenu,uu.NAME,decode(substr(param_str,4,1), 'P','ü','') as Allow,decode(substr(param_str,1,1), 'A','ü','') as Ins,decode(substr(param_str,2,1), 'E','ü','') as Edit,decode(substr(param_str,3,1), 'D','ü','') as Del from USER_MODULE uu,user1 where( user_name='SA'or user_name is null)and user1.srno=uu.srno and uu.ID=uu.ID group by uu.id,uu.name,MainMenu group by uu.id,uu.nameHi
The 'param_str' in DECODE function either should be a bind variable for user input or should be a column of a table. If it is a table/view column then include it in the GROUP BY clause and the query should work.
If you specify a GROUP BY clause in a statement, then the select list can
contain only the following types of expressions:
– GROUP BY expressions
– Constants
– Aggregate functions and the functions USER, UID, and SYSDATE
– Expressions identical to those in the group_by_clause. If the group_by_
clause is in a subquery, then the GROUP BY columns of the subquery must
match the select list of the outer query. Any columns in the select list of the
subquery that are not needed by the GROUP BY operation are ignored without
error.
– Expressions involving the preceding expressions that evaluate to the same
value for all rows in a group
In short, except for the columns in aggregate functions, all columns must be included in the GROUP BY clause.

I see that there are several not needed date to char conversions. I could imaging that they confuse the query merge mechanism. Other than that: try to strip down the query to the smallest posisble set of colum combination. So that you can see where the error comes from.

ORA-00979: not a GROUP BY expression in Oracle11g R2
hi,
I am working in Oracle 9i Environement. I want to update Our production database from Oracle 9i to Oracle11g R2.
Note :- Oracle 9i & 11g R2 are different systems.
We follow the migration through import & Export Commands from Production database to New Database.
One Of user having views, while executing that view in 11g R2 Environment it gives the following error.
ORA-00979: not a GROUP BY expression.
When i run this same Query in Oracle9i Environment is executed Successfully with out errors or warnings.
This type of problem not occurred in all views.
In Problematic view having Decode function with in that another decode method was used & finally group by clause is used.
Please guide to me if any issues in 11g R2 Environment.
Thanx in advance
Vijay Kumar

GROUP BY with parameter - cause error -ORA-00979: not a GROUP BY expression
I generate a query via PreparedStatement. For example:
SELECT when, value FROM test GROUP BY ?;
PrepState.toString(1, "when");
That causing error: ORA-00979: not a GROUP BY expression
My application using query like:
SELECT to_char(data,1), SUM(vlue) as sum FROM test GROUP BY to_char(data, 2);
PrepState.toString(1, "YYYY-MM");
PrepState.toString(2, "YYYY-MM");Ah. Reproduced in the first chunk of PL/SQL below.
The second chunk is a workaround.
Basically, SQL is parsed by the syntax engine and optimizer to get an execution plan. Then you can have a sequence of "bind, execute, fetch, fetch, fetch..., bind, execute..."
Since you can have multiple binds for a single SQL parse, then the fact that the first set of binds all happen to have the same value doesn't mean the next set will.
The optimizer needs to be 100% sure that the value in the select must always be the same as the value in the group by, so you can't have two separate (and therefore potentially different) bind variable mappings. [Given the right circumstances, the optimizer might do all sorts of tricks, such as using materialized views and function-based indexes.]
Misleadingly, it actually fails on the 'EXECUTE' step of DBMS_SQL rather than the PARSE.

Error ORA-00979: not a GROUP BY expression
I have to run a query to list the Product_code, stock_level, and the total quantity ordered
The tables are as follows:
PRODUCT:
PRODUCTCODE PRODDESCRIPTION PRICE STOCKLEVEL
p1 carpet 40 10000
p2 tile 20 100000
p3 pergo 50 50000
PRODLINE:

o1 p2 500
o2 p3 200
o3 p1 600
o3 p3 100
o4 p2 1000
o5 p2 800
Here is my SQL Statement:
SELECT pl.PRODCODE, SUM(pl.QUANTITY), pr.STOCKLEVEL
FROM PRODLINE pl, PRODUCT pr
WHERE pl.PRODCODE=pr.PRODUCTCODE
GROUP BY pl.PRODCODE;
RESULT:

Can someone please assist?Remember the ABC's of GROUP BY:
When you use a GROUP BY clause and/or an aggregate fucntion, then everything in the SELECT clause must be:
(A) an <b>A</b>ggregate function,
(B) one of the "group <b>B</b>y" expressions,
(C) a <b>C</b>onstant, or
(D) something that <b>D</b>epends entirely on the above. (For example, if you "GROUP BY TRUNC(dt)", you can SELECT "TO_CHAR (TRUNC(dt), 'Mon-DD')").
In your query, pr.stocklevel is none of the above.
The previous respondent show how you can make it one of the "group <b>B</b>y" expressions, which is noramlly how you would handle this situation.
Alternatively, you could make it an <b>A</b>ggregate function, like this:
SELECT pl.PRODCODE
, SUM (pl.QUANTITY) AS total_quantity
, MIN (pr.STOCKLEVEL) AS stokclevel
FROM PRODLINE pl
, PRODUCT pr
WHERE pl.PRODCODE = pr.PRODUCTCODE
GROUP BY pl.PRODCODE; -

I am passing parameters to TOTAL_AMOUNT function in a package.the function waht it will do is it will
round off the amount.when i execute this query i am egtting below exception .
ORA-000979: not a GROUP BY expression
SELECT
UTILITIES_PKG.TOTAL_AMOUNT ((SELECT SUM(EII1.QTY) * EII1.PRICE

E.EMP_ID,
E.EMPCUR_ID
) AMOUNT
FROM EMPLOYEE E,
EMPLOYEE_ITEMS EII
WHERE
EII1.EMP_ID=E.IDhave you tried passing the actual parameter value to verify if the package function is the issue?
e.g.
select utilities_pkg.total_amount(100,20,5) from dual
or should it be
SELECT SUM(EII1.QTY * EII1.PRICE) tot_amt
FROM EMPLOYEE_ITEMS EII1,
EMPLOYEE E
WHERE EII1.EMP_ID = E.ID
GROUP BY EII1.ID, EII1.PRICE -
Performance... Why a function column in a view is executed more than once...?
Why a function column created inside a view is executed more than once when called more than once?
EXAMPLE:
create or replace view aux1 as
date_column,
any_function(date_column) column1
from any_table
create or replace view aux2 as
column1 c1,
column1 c2,
column1 c3
from aux1
select * from aux2
It will execute 3 times the function any_function... logically the value will be the same for all columns...
I understand why!... are 3 calls... but...
Why not to create a "small" verification and if the function column was execute replace the second, the third... value? ... instead of execute 3, 4... times...
tks
BragaActually, this is more than a performance issue. This is a consistency problem. If the function is NOT deterministic then you may get different values for each call which is clearly not consistent with selecting 3 copies of the same column from a row. Oracle appears to have fixed this in 9i...
