Pivot type query without aggregate function. Transposing

Hi experts,
Oracle 11g.
I have a table (see code example to reproduce), that has a date, a grouping, and the count of that grouping (determined in another query). I need a pivot type query, but, without the aggregate functions. This is just for a report display. I can not seem to figure this one out. Thanks for your help.
CREATE TABLE temp_task
AS
   SELECT TO_DATE ('15-NOV-2012') validation_date,
          'GROUP 1' AS group_number,
          42 AS monthly_count
     FROM DUAL
   UNION ALL
   SELECT TO_DATE ('14-DEC-2012') validation_date,
          'GROUP 1' AS group_number,
          33 AS monthly_count
     FROM DUAL
   UNION ALL
   SELECT TO_DATE ('15-NOV-2012') validation_date,
          'GROUP 2' AS group_number,
          10 AS monthly_count
     FROM DUAL
   UNION ALL
   SELECT TO_DATE ('14-DEC-2012') validation_date,
          'GROUP 2' AS group_number,
          32 AS monthly_count
     FROM DUAL
   UNION ALL
   SELECT TO_DATE ('15-NOV-2012') validation_date,
          'GROUP 3' AS group_number,
          7 AS monthly_count
     FROM DUAL
   UNION ALL
   SELECT TO_DATE ('14-DEC-2012') validation_date,
          'GROUP 3' AS group_number,
          9 AS monthly_count
     FROM DUAL;Using only SQL I need to return the following:
VALIDATION_DATE | GROUP 1 | GROUP 2 | GROUP 3
11/15/2012 | 42 | 10 | 7
12/14/2012 | 33 | 32 | 9

Hi
You always need to use an aggregate function while pivoting.
Even if you don't really need any aggregation, that is, when what you see in the table is what you'll get in the result set, you still have to use an aggregate function. If there will only be one value contrinuting to each cell, then you can use MIN or MAX. It won't matter which; since there's only 1 value, that value will be the highest of the 1, and it will also be the lowest. For NUMBER columns, you could also use SUM or AVG.
SELECT       *
FROM       temp_task
PIVOT       ( MIN (monthly_count)
         FOR group_number IN ( 'GROUP 1'
                             , 'GROUP 2'
                    , 'GROUP 3'
ORDER BY validation_date
; Output:
VALIDATION_ 'GROUP 1' 'GROUP 2' 'GROUP 3'
15-Nov-2012         42         10          7
14-Dec-2012         33         32          9It sounds like you're doing real aggregation someplace, to get monthly_count. Maybe it would be simpler and more efficient to do the pivoting at that point. What is the big picture here? Post some sample data as it is before you compute monthly_count, and the results you want from that data (if different from what you've already posted), and then let's see if we can't aggregte it and pivot it at the same time.

Trying to create a Histogram type/object for aggregate functions

Hi,
I am trying to create an aggregate function that will return a histogram
type.
It doesn't have to be an object that is returned, I don't mind returning
a string but I would like to keep the associative array (or something
else indexed by varchar2) as a static variable between iterations.
I started out with the SecondMax example in
http://www.csis.gvsu.edu/GeneralInfo/Oracle/appdev.920/a96595/dci11agg.htm#1004821
But even seems that even a simpler aggregate function like one strCat
below (which works) has problems because I get multiple permutations for
every combination. The natural way to solve this would be to create an
associative array as a static variable as part of the Histogram (see
code below). However, apparently Oracle refuses to accept associate
arrays in this context (PLS-00355 use of pl/sql table not allowed in
this context).
If there is no easy way to do the histogram quickly can we at least get
something like strCat to work in a specific order with a "partition by
... order by clause"? It seems that even with "PARALLEL_ENABLE"
commented out strCat still calls merge for function calls like:
select hr,qtr, count(tzrwy) rwys,
noam.strCat(cnt) rwycnt,
noam.strCat(tzrwy) config,
sum(cnt) cnt, min(minscore) minscore, max(maxscore) maxscore from
ordrwys group by hr,qtr
Not only does this create duplicate entries in the query result like
"A,B,C" and "A,C,B" it seems that the order in rwycnt and config are not
always the same so a user can not match the results based on their
order.
The difference between my functions and functions like sum and the
secondMax demonstrated in the documentation is that secondMax does not
care about the order in which it gets its arguments and does not need to
maintain an ordered set in order to return the correct results. A good
example of a built in oracle function that does care about all its
arguments and probably has to maintain a similar data structure to the
one I want is the PERCTILE_DISC function. If you can find the code for
that function (or something like it) and forward a reference to me that
in itself would be very helpful.
Thanks,
K.Dingle

Hi Marsh,
To achieve your requirement, you may reference the below query.
--pivot the table to get the expected output
;WITH cte AS(
SELECT *,ROW_NUMBER() OVER(PARTITION BY LocationDesc,BandGroup ORDER BY BandGroup) AS rn FROM [TmpBandGroup]
SELECT LocationDesc,[>=360],[>=300],[>=270],[>=240],[<240]
FROM cte
PIVOT
(MAX(EmployeeName) FOR BandGroup IN([>=360],[>=300],[>=270],[>=240],[<240])) PVT
ORDER BY LOCATIONDESC
--the pivot result can be validated with the queries below
;WITH cte AS(
SELECT *,ROW_NUMBER() OVER(PARTITION BY LocationDesc,BandGroup ORDER BY BandGroup) AS rn FROM [TmpBandGroup]
,cte2 AS
SELECT RN, LocationDesc,[>=360],[>=300],[>=270],[>=240],[<240]
FROM cte
PIVOT
(MAX(EmployeeName) FOR BandGroup IN([>=360],[>=300],[>=270],[>=240],[<240])) PVT
SELECT LocationDesc, COUNT([>=360]) [>=360] ,COUNT([>=300]) [>=300],COUNT([>=270]) [>=270],COUNT([>=240]) [>=240],COUNT([<240]) [<240]
FROM cte2
group by LocationDesc
ORDER BY LocationDesc
SELECT LocationDesc,bandgroup,COUNT(EmployeeName) FROM [TmpBandGroup] group by LocationDesc ,bandgroup
ORDER BY LocationDesc,bandgroup DESC

Update of a table from a select query with aggregate functions.

Hello All,
I have problem here:
I have 2 tables A(a1, a2, a3, a4, a4....... ) and B( a1, a2, b1, b2, b3). I need to calculate the avg(a4-a3), Max(a4-a3) and Min(a4-a3) and insert it into table B. If the foreign keys a1, a2 already exist in table B, I need to do an update of the computed values into column b1, b2 and b3 respectively, for a1, a2.
Q1. Is it possible to do this with a single query ? I would prefer not to join A with B because the table A is very large. Also columns b1, b2 and b3 are non-nullable.
Q2. Also if a4 and a3 are timestamps what is the best way to find the average? A difference of timestamps yields INTERVAL DAY TO SECOND over which the avg function doesn't seem to work. The averages, max and min in my case would be less than a day and hence all I need is to get the data in the hh:mm:ss format.
As of now I'm using :
TO_CHAR(TO_DATE(ABS(MOD(TRUNC(AVG(extract(hour FROM (last_modified_date - created_date))*3600 +
extract( minute FROM (last_modified_date - created_date))*60 +
extract( second FROM (last_modified_date - created_date)))
),86400)),'sssss'),'hh24":"mi":"ss') AS avg_time,
But this is very long drawn. Something more compact and efficient would be nice.
Thanks in advance for your inputs.

Hi,
Thanks everyone for such fast replies. Malakshinov's example worked fine for me as far as updating the table goes. As for the timestamp computations, I'm posting additional info: Sorry, I don't understand.
If Malakshinov's example worked for updating the table, but you still have problems, does that mean you have to do something else besides update the table? If so, what?
Oracle version : Oracle Database 11g Enterprise Edition Release 11.2.0.1.0
Here are the table details :
DESC Table A
Name Null Type
ID               NOT NULL NUMBER
A1               NOT NULL VARCHAR2(4)
A2               NOT NULL VARCHAR2(40)
A3               NOT NULL VARCHAR2(40)
CREATED_DATE NOT NULL TIMESTAMP(6)
LAST_MODIFIED_DATE TIMESTAMP(6) DESCribing the tables can help clarify some things, but it's no substitute for posting CREATE TABLE and INSERT statements. With only a description of the table, nobody can re-create the problem or test their ideas. Please post CREATE TABLE and INSERT statements for both tables as they exist before the MERGE. If table b doen't contain any rows before the MERGE, then just say so, but you still need to post a CREATE TABLE statement for both tables, and INSERT statements for table a.
The objective is to compute the response times : avg (LAST_MODIFIED_DATE - CREATED_DATE), max (LAST_MODIFIED_DATE - CREATED_DATE) and min (LAST_MODIFIED_DATE - CREATED_DATE) grouped by A1 and A2 and store it in table B under AVG_T, MAX_T and MIN_T. Since AVG_T, MAX_T and MIN_T are only used for reporting purposes we have kept it as Varchar (though I think keeping it as timestamp would make more sense). I think a NUMBER would make more sense (the number of minutes, for example), or perhaps an INTERVAL DAY TO SECOND. If you stored a NUMBER, it would be easy to compute averages.
In table B the times are stored in the format : hh:mm:ss. We don't need milliseconds precision. If you don;'t need milliseconds, then you should use DATE instead of TIMESTAMP. The functions for manipulating DATEs are much better.
Hence I was calculating is as follows:
-- Avg Time
TO_CHAR(TO_DATE(ABS(MOD(TRUNC(AVG(extract(hour FROM (last_modified_date - created_date))*3600 +
extract( minute FROM (last_modified_date - created_date))*60 +
extract( second FROM (last_modified_date - created_date)))
),86400)),'sssss'),'hh24":"mi":"ss') AS avg_time,
--Max Time
extract (hour FROM MAX(last_modified_date - created_date))||':'||extract (minute FROM MAX(last_modified_date - created_date))||':'||TRUNC(extract (second FROM MAX(last_modified_date - created_date))) AS max_time,
--Min Time
extract (hour FROM MIN(last_modified_date - created_date))||':'||extract (minute FROM MIN(last_modified_date - created_date))||':'||TRUNC(extract (second FROM MIN(last_modified_date - created_date))) AS min_timeIs this something that has to be done before or after the MERGE?
Post the complete statement.
Is this part of a query? Where's the SELECT keyword?
Is this part of a DML operation? Where's the INSERT, or UPDATE, or MERGE keyword?
What are the exact results you want from this? Explain how you get those results.
Is the code above getting the right results? Are you just asking if there's a better way to get the same results?
You have to explain things very carefully. None of the people who want to help you are familiar with your application, or your needs.

How to write SQL query and apply aggregate functions on it

Hello experts,
Iu2019ve a task to write SQL query on tree tables and do inner join on them. Iu2019ve accomplish this task by using T-CODE SQVI. However now I need to write a query and apply SQL functions on it i.e. Add, Count, Max and Min etc. Please can someone tell me how I can write SQL query with aggregate functions in SAP?
Thanks a lot in advance

HI Mr. Cool
you can see the below code for using aggregate functions.
where ARTIST and SEATSOCCU are the field names for which you want to perform these functions.
DATA: TOTAL_ENTRIES TYPE I,
      TOTAL_ATT TYPE I,
      MAX_ATT TYPE I,
      AVG_ATT TYPE I.
SELECT COUNT( DISTINCT ARTIST )
       SUM( SEATSOCCU )
       MAX( SEATSOCCU )
       AVG( SEATSOCCU ) FROM YCONCERT INTO (TOTAL_ENTRIES, TOTAL_ATT,
MAX_ATT, AVG_ATT).

Why doesn't PIVOT clause work with COLLECT aggregate function in 11g ?

Hello all !
I am really puzzled as to what is considered an aggregate function in the context of the PIVOT clause in 11g.
I have been toying with quite a few things related to collections lately and this arose as an aside :
CREATE TABLE TEST_COLL
   NODE_ID    VARCHAR2(15 CHAR) NOT NULL,
   NODE_VALUE VARCHAR2(45 CHAR) NOT NULL,
   NODE_LEVEL NUMBER(1)         NOT NULL
CREATE OR REPLACE TYPE TREE_NODE AS OBJECT
   NODE_KEY VARCHAR2( 15 CHAR),
   NODE_NAME VARCHAR2(127 CHAR)
CREATE OR REPLACE TYPE TREE_NODES AS TABLE OF TREE_NODE NOT NULL;At this stage I am sure we all agree that the query
SELECT NODE_LEVEL,
       CAST(COLLECT(TREE_NODE(NODE_ID, NODE_VALUE)) AS TREE_NODES) AS NODES

GROUP BY NODE_LEVEL;is perfectly valid as the COLLECT function is an aggregate function according to the [Official Documentation|http://docs.oracle.com/cd/E11882_01/server.112/e10592/functions031.htm#i1271564]
But then, one of the following two queries should work

       );yet, both fail with
ORA-56902: expect aggregate function inside pivot operationInvestigating further, I found the same behaviour when using XMLAGG as the aggregate function in the PIVOT clause.
Is this normal ? And if it is, is there any other way to achieve the result I was anticipating ?

Most likely a bug. But you can bypass it by using any other aggregate making sure group consists of a single row and apply collect to a pivoted value. Yes, the cost is double aggregation. And also there is another cost - you would need to create MAP member function otherwise aggreations like MAX/MIN, etc. will not work:
CREATE OR REPLACE TYPE TREE_NODE AS OBJECT
   NODE_KEY VARCHAR2( 15 CHAR),
   NODE_NAME VARCHAR2(127 CHAR),
   map member function f return varchar2
Type created.
CREATE OR REPLACE TYPE BODY TREE_NODE AS
map member function f return varchar2 is
begin
     return NODE_NAME;
end f;
end;
Type body created.
CREATE OR REPLACE TYPE TREE_NODES AS TABLE OF TREE_NODE NOT NULL
Type created.

Aggregate function in the query

Hi gurus,
What makes presentation layer send queries with Aggregate( by ) function eventhough this function is not used in the column formulas?
Now comes a long explanation - only for the patient ones :-)
I am working OBIEE / Essbase.
A strange thing happened to one of my reports - exactly the same report (pivot) in production (old repository) works fine, but brings wrong results on the new repository.
I found out that SQL sent to OBIEE is different.
With old repository, it sends a query with 'Aggregate ( by)' function used for measures. However with the new one, it sends just column names without the Aggregate.
Where shall I look for the difference?
-- OLD (Good) query -----------
SELECT DIM_BATCH_HEADERS."Gen3,DIM_BATCH_HEADERS" saw_0,
PROD_QTY.PROD_ACTUAL_QTY_KG/1000 saw_1,
DIM_COMPONENT."Gen3,DIM_COMPONENT" saw_2, ' ' saw_3,
COST.COMP_ACTUAL_COST_ILS_PER_TON saw_4, 0 saw_5,
COST.ACTUAL_COST_K_ILS saw_6, 0 saw_7,
AGGREGATE(saw_1 BY ),
AGGREGATE(saw_4 BY ),
AGGREGATE(saw_6 BY ),
AGGREGATE(saw_1 BY saw_0, saw_5),
AGGREGATE(saw_4 BY saw_0, saw_5),
AGGREGATE(saw_6 BY saw_0, saw_5)
FROM "COP_MAAD#1" WHERE (COMP_QTY.COMP_RELEVANT > 0)
AND (DIM_TIME."YEAR" = '2009')
AND (DIM_BATCH_HEADERS."Gen2,DIM_BATCH_HEADERS" = 'ABC')
ORDER BY saw_1 DESC, saw_4 DESC, saw_0, saw_2, saw_3, saw_5, saw_7
-- NEW (Incorrect) Query ---------------
SELECT DIM_BATCH_HEADERS."Gen3,DIM_BATCH_HEADERS" saw_0,
PROD_QTY.PROD_ACTUAL_QTY_KG/1000 saw_1,
DIM_COMPONENT."Gen3,DIM_COMPONENT" saw_2,
' ' saw_3, COST.COMP_ACTUAL_COST_ILS_PER_TON saw_4,
0 saw_5,
COST.ACTUAL_COST_K_ILS saw_6,
0 saw_7 FROM "COP_MAAD#1"
WHERE (COMP_QTY.COMP_RELEVANT > 0) AND (DIM_TIME."YEAR" = '2009')
AND (DIM_BATCH_HEADERS."Gen2,DIM_BATCH_HEADERS" = 'ABC') ORDER BY saw_1 DESC, saw_4 DESC

Issue in pivot while using aggregate functions

when I use this below query in oracle sql developer
------------->select sum(round(8.08/0.54,2)*30) from dual.
i am getting result as 448.8.it is a correct value
but i use this below queries in pivot as same like above query i am getting result of doubled value 914.4.
PIVOT
SUM(round(ROUND(sellout,2)/6,2)) AS LAST_6_MON_SELL_OUT,
SUM(ROUND(inventory,2)) AS INVENTORY_INTINS_1,
Sum(round(ROUND(inventory,2)/round(ROUND(sellout,2)/6,2),2)*30) As Stockperday
FOR PRODUCT IN (56,78)
actually i am getting value for SUM(round(ROUND(sellout,2)/6,2)) is 0.54,*SUM(ROUND(inventory,2))* is 8.08 i the above query ,but i am getting wrong value for this aggregate function Sum(round(ROUND(inventory,2)/round(ROUND(sellout,2)/6,2),2)30)* as 914.4.but actual value is 448.8
why this problem.can anybody explain me.why this problem

Aggregate function in native query (EJB 3.0)

How do you run a aggregate function in a native query? I have a particular use case, for reporting purposes, where the result set is too large to fetch the actual CMP collection, thus I need to execute a native count/avg select. I want some thing like,
Integer totalRecords = (Integer)
       em.createNativeQuery("select count(*) from records").getSingleResult();

Oracle is intelligent enough to use index only if query result filtering is based on it and result set is less than 5% of the total data set.Sorry to be blunt but that 5% stuff is nonsense.
Here since the index column is not used in the WHERE clause, oracle performs full table scan.That's not true either. Under the right circumstances the optimizer can use the index, even without a WHERE clause in the query:
SQL> create table t as select * from dba_objects where object_type is not null;
Table created.
SQL> alter table t modify object_type not null;
Table altered.
SQL> create index t_idx on t(object_type);
Index created.
SQL> explain plan for
2 select object_type, count(*) from t group by object_type;
Explained.
| Id | Operation             | Name | Rows | Bytes | Cost (%CPU)| Time     |
|   0 | SELECT STATEMENT      |       |    44 |   396 |    60   (7)| 00:00:01 |
|   1 | HASH GROUP BY        |       |    44 |   396 |    60   (7)| 00:00:01 |
|   2 |   INDEX FAST FULL SCAN| T_IDX | 72474 |   636K|    57   (2)| 00:00:01 |
-------------------------------------------------------------------------------With the OP's query, it (apparently) can not be satisfied by using only the index.
WHERE TO_CHAR(COL) = TO_CHAR(COL)I don't even know what this means. Usually if you perform a function on an indexed column, the optimizer will not use the index (unless of course it's an fbi).

Rounding the aggregate function in a pivot table

How do I round the avg(GRADE) when I tried just wrapping it around the avg function I get an error message saying expect aggregate function inside pivot operation
pivot
( avg(GRADE)
for Column
in ('1012222','2221112','333113' );
Thanks for the help.
Edit : Sorry wasn't very clear all thats shown is the pivot part of the statement.

Hi, and welcome to the forum.
It is hard to see how your piece of pseudo SQL is related to your subject title.
There should not be any problem in wrapping ROUND around AVG:
SQL> select deptno, round(avg(sal)) from emp
where deptno in (10,20)
group by deptno
    DEPTNO ROUND(AVG(SAL))
        20            2175
        10            2917
2 rows selected.Edit: Sorry, did not recognize you query bit. You probably are asking about this:
SELECT * FROM
   (SELECT deptno, sal FROM emp)
    PIVOT
   (ROUND(AVG(sal)) FOR deptno IN (10 AS Accounting, 30 AS Sales));
Error at line 4
ORA-56902: expect aggregate function inside pivot operationSuppose you have to (There might be other ways)
SQL> SELECT Round(accounting), round(sales) FROM
   (SELECT deptno, sal FROM emp)
    PIVOT
   (AVG(sal) FOR deptno IN (10 AS Accounting, 30 AS Sales));
ROUND(ACCOUNTING) ROUND(SALES)
             2917         1567

What is it that you're trying to accomplish with this?
The reason I ask is that pivoting data is a display function and therefore best left to the application or reporting tier.
If you're going to insist on "driving screws with a hammer" and really want to do this in SQL, the next question is, Is there a set number of "Stages" that will exist? Is it always going to be 3 stages and only 3 stages?
If the answer is YES, there will be a fixed number of stages, then it's a simple thing to do with either a PIVOT or CASE statements. (my personal preference is to use case statements, especially if you're pivoting 2 or more columns)
If the answer is NO, the number is stages can vary... You're left with a Dynamic PIVOT. Dynamic Pivots are a bit more complex to write but there is enough sample code out on the interwebs that you won't have a problem finding the correct syntax.
The real problem with a Dynamic Pivot query is the fact that it's pretty much useless. You can't do much (if anything at all) with it... Due to the fact that they have variable numbers of columns, they can't be used in views or procs and I can't think of
a singe, off the shelf, reporting platform that will allow accommodate data source that has a different number of columns every time it executes... So unless you're going to be content looking at the results in SSMS or developing a custom application, I don't
see the point.
Also... Aggregates aren't a problem based on the data you're showing. You only have 1 start time and 1 end time per stage. Using either the MIN or MAX aggregate functions will work to give you the desired result.
Anyway, hope that helps,
Jason

Aggregate function on "large value type"

We are constrained to use a model that stores records in a main table and various attributes of the record in a second table. Something like this: main record table CAR, attribute table CAR_DETAILS with CAR_DETAILS have key value pairs like "color"
"blue" and "doors" "4".
For reports we need to flatten the one to many nature of this to get CAR and color and doors by using an aggregate function like:
car_id, max(car_detail.value) filtered on car_detail.key = "color", max(car_detail.value) filtered on car_detail.key = "doors".
This works on other tables but the car_detail table (shall we say) appears to store its values as blobs. In any case when we attempt to aggregate we get "The query uses an aggregate function on a large value type expression. Large value type expressions
can not be aggregated."
Since we can't change the model, we would need to use another function to change this to a smaller string (or date, these are actually mostly date), but none of the very limited set of functions available seems to work to make this aggregation possible (and
there is no "first" or anything else similar).
The list of functions available in Report Model Queries can be found at https://msdn.microsoft.com/en-us/library/ee210538.aspx
Appreciate any ideas on how to solve this

I found a work around : create a second dataset reversing the direction:
car_detail.key, car_detail.value, car_id
with this filtered by car_detail.key = "color" (or doors etc)
Then use a lookup from the first dataset to the second to display the data:
=Lookup(Fields!car_Id.Value,Fields!Icar_Id.Value,Fields!car_detail.Value, "DataSet2")
where the 1st field is in the main report dataset, the second and third are in the lookup dataset, and the 4th parameter is the name of the lookup dataset.
Would still really like to have a solution that allows aggregation for ease of use and efficiency.

Should your query be a valid SQL query?
I can't think that the query you have would be valid in a SQL plus window.
