Using aggregrate functions without group by

Hi
I have a query which is
select empno,deptno,count(*) from emp group by empno,deptno;
Is there any thing which will help me to return empno,deptno without using group by clause?
Appreciate your help on the above?
Thanks & Regards
Thakur Manoj R

This will give the same result:
select empno, deptno, count(*) over (partition by empno, deptno) from emp;If you want to see the number of employees in the same department you could use:
select empno, deptno, count(*) over (partition by deptno) from emp;But what is your intention? What is wrong about "group by"?

Nested group function without group xmlagg

I am getting nested group function without group by xmlagg when using the xmlagg function inside another xmlagg function. Find the table structure and sample data here,
CREATE TABLE "TEST_TABLE"
   ("KEY" NUMBER(20,0),
    "NAME" VARCHAR2(50 ),
    "DESCRIPTION" VARCHAR2(100 )
   Insert into TEST_TABLE (KEY,NAME,DESCRIPTION) values (1,'sam','desc1');

         xmlagg(
           xmlelement("emp"

           , xmlelement("Descriptions",
              xmlforest(description as "Desc")
       ) as clob indent
       ) as t
      from test_table;This is working fine, but xml created with empty elements for Descriptions element for key 3 and 4 which has null values. I need don't need Descriptions element in the xml when it has null value. Please help me to resolve this.

You can do it with a correlated subquery :
SQL> select xmlserialize(document
2           xmlelement("root",
3             xmlagg(
4               xmlelement("emp"
5               , xmlforest(
6                   t.key as "ID"
7                 , t.name as "ename"
8                 , (
9                     select xmlagg(
10                              xmlelement("Desc", d.description)
11                              order by d.description -- if necessary
12                            )
13                     from test_desc d
14                     where d.key = t.key
15                   ) as "Descriptions"
16                 )
17               )
18             )
19           ) as clob indent
20         )
21 from test_table t;
XMLSERIALIZE(DOCUMENTXMLELEMEN
<root>
<emp>
    <ID>1</ID>
    <ename>sam</ename>
    <Descriptions>
      <Desc>desc1_1</Desc>
      <Desc>desc1_2</Desc>
      <Desc>desc1_3</Desc>
    </Descriptions>
</emp>
<emp>
    <ID>2</ID>
    <ename>max</ename>
    <Descriptions>

Or an OUTER JOIN + GROUP-BY :
select xmlserialize(document
         xmlelement("root",
           xmlagg(
             xmlelement("emp"
             , xmlforest(
                 t.key as "ID"
               , t.name as "ename"
               , xmlagg(
                   xmlforest(d.description as "Desc")
                   order by d.description -- if necessary
                 ) as "Descriptions"
         ) as clob indent
from test_table t
     left outer join test_desc d on d.key = t.key
group by t.key
       , t.name

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.

Using decode function without negative values

Hi friends
I am using oracle 11g
I have at doubt regarding the following.
create table Device(Did char(20),Dname char(20),Datetime char(40),Val char(20));
insert into Device values('1','ABC','06/13/2012 18:00','400');
insert into Device values('1','abc','06/13/2012 18:05','600');
insert into Device values('1','abc','06/13/2012 18:55','600');
insert into Device values('1','abc','06/13/2012 19:00','-32768');
insert into Device values('1','abc','06/13/2012 19:05','800');
insert into Device values('1','abc','06/13/2012 19:10','600');
insert into Device values('1','abc','06/13/2012 19:15','900');
insert into Device values('1','abc','06/13/2012 19:55','1100');
insert into Device values('1','abc','06/13/2012 20:00','-32768');
insert into Device values('1','abc','06/13/2012 20:05','-32768');
Like this I am inserting data into table for every 5 minutes Here i need the result like
output:
Dname 18:00 19:00 20:00
abc 400 -32768 -32768
to retrieve this result i am using decode function
SELECT Dname,
MAX(DECODE ( rn , 1,val )) h1,
MAX(DECODE ( rn , 2, val )) h2,
FROM
(SELECT Dname,Datetime,row_number() OVER
(partition by Dname order by datetime asc) rn FROM Device
where substr(datetime,15,2)='00' group by Dname.
According to above data expected result is
Dname 18:00 19:00 20:00
abc 400 600(or)800 1100
This means I dont want to display negative values instead of that values i want to show previous or next value.
Edited by: 913672 on Jul 2, 2012 3:44 AM

Are you looking for something like this?
select * from
select dname,
       datetime,
       val,
       lag(val) over (partition by upper(dname) order by datetime) prev_val,
       lead(val) over (partition by upper(dname) order by datetime) next_val,
       case when nvl(val,0)<0 and lag(val) over (partition by upper(dname) order by datetime) >0 then
         lag(val) over (partition by upper(dname) order by datetime)
       else
         lead(val) over (partition by upper(dname) order by datetime)
       end gt0_val
from device
order by datetime
where substr(datetime,15,2)='00';Please take a look at the result_column gt0_val.

Aggregate functions without group by clause

hi friends,
i was asked an interesting question by my friend. The question is...
There is a DEPT table which has dept_no and dept_name. There is an EMP table which has emp_no, emp_name and dept_no.
My requirement is to get the the dept_no, dept_name and the no. of employees in that department. This should be done without using a group by clause.
Can anyone of you help me to get a solution for this?

select distinct emp.deptno,dname
,count(*) over(partition by emp.deptno)
from emp
,dept
where emp.deptno=dept.deptno;

Can i use Lead function with Group by function

I could use this query and get right ouput since i define product id =2000
select product_id, order_date,
lead (order_date,1) over (ORDER BY order_date) AS next_order_date
from orders
where product_id = 2000;
But can i run this query by Group by Function
for example
select product_id, order_date,
lead (order_date,1) over (ORDER BY order_date) AS next_order_date
from orders
group by product_id ;

Using count function with grouped records

Hi all,
This seems like it should be real easy but I have yet to figure out a simple way to do this.
Suppose I want to count Opportunities that are grouped by Sales Rep. At run-time I am filtering this list with a parameter for Sales Stage and created date.
I've simplified this greatly, but here's what my setup looks like now:
Sales Rep* ---------Count*_
<?for-each-group:Opportunity[SalesStage=param1 and Created>param2];./salesrep?>
<?salesrep?>-------<?count(current-group()/Id)?>
<?end for-each-group?>
Total_
The only solution I have so far to get my grand total is to create a variable and keep a running total which I'll then display in the Total column. While it works, it seems like there should be an easier way, like doing a simple count(Id) to get the grand total. But since the Total appears after the end for-each-group, I lose the filter that was applied to the group so that count is invalid.
Any thoughts from the experts?
Thanks!

To get grand total
use
<?count(/Oppurtunity[SalesStage=param1 and Created>param2]/Id)?>since you did not mention the complete xml, i assumed, Opportunity as the Root.
if not, put the full path from the root.
if you give some xml sample, and explain the output you wanted, we can fix it immediately.
go thru these too..some thing can be pulled from here .

Using DAQmx functions without installation

Good evening everybody,
I have an instrumentation problem linked to DAQmx. I would like to communicate with an instrument using NIDAQmx tasks. I use an environment program system : visual studio 2003. At the end, I want to produce a dll. This dll, I want to put it on another computer. The question is the following. If I want to launch the dll by calling it, will I need NI-DAQ on the other computer or a software to use the dll ?
When I tried to produce an exe with a VI, I needed to have Labview RunTime to launch the exe. If I want to launch the dll, will I be able to use the dll alone on the computer, without the installation of NIDAQ. Can I use the tasks only with the dll (since I need Run Time for the .exe, do I need Run Time also). ?
I am sorry, it must be not clear. But I am available to explain you more the problem.
Best regards.
Thank you.

Solved!
Go to Solution.

Since you have LabVIEW installed on your computer, the Run-Time is not required for running LabVIEW executables.
But if you decide to use your LabVIEW executable on an other computer, you will need to install the LabVIEW Run-Time on it. You can also build an installer which will contain your program and addtionnal components (such as LabVIEW Run-Time and required drivers). Building an installer avoid to download and install the components separately.
For more information regarding installer, you can look into LabVIEW's help (Building an Installer (Windows)) or follow Core 2 training course.
If your program uses NI-488.2 driver, you will need to install it on your computer.
Installing LabVIEW Run-Time is only required if your program which contains DLL calls is a LabVIEW executable.

Jérémy C.

SSRS 2008R2 : Not able to use Previous aggregrate function in matrix columns cell

Hi Expert,
I have used a matrix tablix in my report. It is working fine. But when I am trying to use Previous aggregrate in one matrix column cell I get the below error:
The use of previous aggregrate function ia a tablix cell with in 'Tablix1' is not supported.
Please help me regarding that.
Thanks Rana

Hi Rana,
In your scenario, you use previous function in the “Data” cell, right? Previous function cannot be used in the overlapping parts of row group and column group. One workaround of this issue is use custom code to get the previous value.
Public Shared previous as Integer
Public Shared current as Integer
Public Shared Function GetCurrent(Item as Integer) as Integer
     previous=current
     current=Item
     return current
End Function
Public Shared Function GetPrevious()
     return previous
End Function
Then you can use the expression below in the “Data” cell to get the previous value:
=Code.GetCurrent(fields!Score.Value) & "-Previous-" & iif(Code.GetPrevious()=0,"",Code.GetPrevious())
If you have any questions, please feel free to ask.
Regards,
Charlie Liao

OBIEE: Incorrect SQL - with count function uses ORDER BY instead GROUP BY

I made a basic report that is a client count; I want to know how many clients the company have.
But, when I run this report, OBIEE generates a ORDER BY sentence, instead a GROUP BY. Remember that I'm using count function, that is a agregation.
The SQL generated was:
select 'N0' as c1,
count(*) as c2
from
(select distinct T1416.CLIENT_INTER_KEY as c1
from
(select *
from prd.D_SERVICE where SOURCE_SYS in ('ARBOR','PPB') and DW_SERV_ST_ID in (100000003,100000009)) T1836,
(select *
from prd.D_CLIENT) T1416,
(select *
from prd.D_CUSTOMER_ACCOUNT where SOURCE_SYS In ('ARBOR','PPB')) T1515
where ( T1416.DW_CLIENT_ID = T1515.DW_CLIENT_ID and T1515.DW_CUST_ACCT_ID = T1836.DW_CUST_ACCT_ID and T1836.MSISDN = '917330340' )
) D1
order by c1
The error that I receive is:
"Query Status: Query Failed: [nQSError: 16001] ODBC error state: S1000 code: -1005018 message: [Sybase][ODBC Driver][Adaptive Server Anywhere]Illegal ORDER BY item Order Item: 'N0',
-- (opt_OrderBy.cxx 429) .
[nQSError: 16011] ODBC error occurred while executing SQLExtendedFetch to retrieve the results of a SQL statement."
If I substitute ORDER BY with GROUP BY and test it in Sybase, Ithe query runs without any problem.
select 'N0' as c1,
count(*) as c2
from
(select distinct T1416.CLIENT_INTER_KEY as c1
from
(select *
from prd.D_SERVICE where SOURCE_SYS in ('ARBOR','PPB') and DW_SERV_ST_ID in (100000003,100000009)) T1836,
(select *
from prd.D_CLIENT) T1416,
(select *
from prd.D_CUSTOMER_ACCOUNT where SOURCE_SYS In ('ARBOR','PPB')) T1515
where ( T1416.DW_CLIENT_ID = T1515.DW_CLIENT_ID and T1515.DW_CUST_ACCT_ID = T1836.DW_CUST_ACCT_ID and T1836.MSISDN = '917330340' )
) D1
group by c1
Do you know why OBIEE generates this SQL??? Why uses, with a aggregation function, a ORDER BY and not a GROUP BY? How can I resolve this problem???
Regards,
Susana Figueiredo

Verify your repository design and make sure that you have defined count aggregate on fact column. You would also need to define the content level of each dimension in fact table.

SQL Performance issue: Using user defined function with group by

Hi Everyone,
im new here and I really could need some help on a weird performance issue. I hope this is the right topic for SQL performance issues.
Well ok, i create a function for converting a date from timezone GMT to a specified timzeone.
CREATE OR REPLACE FUNCTION I3S_REP_1.fnc_user_rep_date_to_local (date_in IN date, tz_name_in IN VARCHAR2) RETURN date
IS
tz_name VARCHAR2(100);
date_out date;
BEGIN
SELECT
to_date(to_char(cast(from_tz(cast( date_in AS TIMESTAMP),'GMT')AT
TIME ZONE (tz_name_in) AS DATE),'dd-mm-yyyy hh24:mi:ss'),'dd-mm-yyyy hh24:mi:ss')
INTO date_out
FROM dual;
RETURN date_out;
END fnc_user_rep_date_to_local;The following statement is just an example, the real statement is much more complex. So I select some date values from a table and aggregate a little.
select
stp_end_stamp,
count(*) noi
from step
where
stp_end_stamp
BETWEEN
to_date('23-05-2009 00:00:00','dd-mm-yyyy hh24:mi:ss')
AND
to_date('23-07-2009 00:00:00','dd-mm-yyyy hh24:mi:ss')
group by
stp_end_stampThis statement selects ~70000 rows and needs ~ 70ms
If i use the function it selects the same number of rows ;-) and takes ~ 4 sec ...
select
fnc_user_rep_date_to_local(stp_end_stamp,'Europe/Berlin'),
count(*) noi
from step
where
stp_end_stamp
BETWEEN
to_date('23-05-2009 00:00:00','dd-mm-yyyy hh24:mi:ss')
AND
to_date('23-07-2009 00:00:00','dd-mm-yyyy hh24:mi:ss')
group by
fnc_user_rep_date_to_local(stp_end_stamp,'Europe/Berlin')I understand that the DB has to execute the function for each row.
But if I execute the following statement, it takes only ~90ms ...
select
fnc_user_rep_date_to_gmt(stp_end_stamp,'Europe/Berlin','ny21654'),
noi
from
select
stp_end_stamp,
count(*) noi
from step
where
stp_end_stamp
BETWEEN
to_date('23-05-2009 00:00:00','dd-mm-yyyy hh24:mi:ss')
AND
to_date('23-07-2009 00:00:00','dd-mm-yyyy hh24:mi:ss')
group by
stp_end_stamp
)The execution plan for all three statements is EXACTLY the same!!!
Usually i would say, that I use the third statement and the world is in order. BUT I'm working on a BI project with a tool called Business Objects and it generates SQL, so my hands are bound and I can't make this tool to generate the SQL as a subselect.
My questions are:
Why is the second statement sooo much slower than the third?
and
Howcan I force the optimizer to do whatever he is doing to make the third statement so fast?
I would really appreciate some help on this really weird issue.
Thanks in advance,
Andi

Hi,
The execution plan for all three statements is EXACTLY the same!!!Not exactly. Plans are the same - true. They uses slightly different approach to call function. See:
drop table t cascade constraints purge;
create table t as select mod(rownum,10) id, cast('x' as char(500)) pad from dual connect by level <= 10000;
exec dbms_stats.gather_table_stats(user, 't');
create or replace function test_fnc(p_int number) return number is
begin
    return trunc(p_int);
end;
explain plan for select id from t group by id;
select * from table(dbms_xplan.display(null,null,'advanced'));
explain plan for select test_fnc(id) from t group by test_fnc(id);
select * from table(dbms_xplan.display(null,null,'advanced'));
explain plan for select test_fnc(id) from (select id from t group by id);
select * from table(dbms_xplan.display(null,null,'advanced'));Output:

I want single update query without use the function.

I want to update sells_table selling_code field with max date product_code from product table.
In product table there is multiple product_code date wise.
I have been done it with below quey with the use of function but can we do it in only one update query
without use the function.
UPDATE sells_table
SET selling_code = MAXDATEPRODUCT(ctd_vpk_product_code)
WHERE NVL(update_product_flag,0) = 0 ;
CREATE OR REPLACE FUNCTION HVL.maxdateproduct (p_product IN VARCHAR2) RETURN NUMBER
IS
max_date_product VARCHAR2 (100);
BEGIN
BEGIN
SELECT NVL (TRIM (product_code), 0)
INTO max_date_product
FROM (SELECT product_code, xref_end_dt
FROM product
WHERE TO_NUMBER (p_product) = pr.item_id
ORDER BY xref_end_dt DESC)
WHERE ROWNUM = 1; -- It will return only one row - max date product code
EXCEPTION
WHEN OTHERS
THEN
RETURN 0;
END;
RETURN max_date_product;
END maxdateproduct;
Thanks in Advance.

Hi,
Something like this.
update setlls_table st
        set selling_code =(select nvl(trim(product_code)) from
                              (select product_code
                                      , rank() over (partition by item_id order by xref_end_dt DESC) rn
                                   from product
                               ) pr
                               where rn =1
                                     and pr.item_id = st.ctd_vpk_product_code
                           ) where NVL(update_product_flag,0) = 0 ;As such not tested due to lack of input sample.

Max value without using max() function

Hi
Is there any way to get the max value from a table without using MAX() function
Thanks

well if you think about it i'm sure you'll find a solution
what does max(field) means, it simply is the value of the field where no other value of the same field that is > than this value exists.
consider the following :
table TAB(
fld NUMBER(5));
translate the logic and you'll have
select a.fld from TAB a where NOT EXISTS(select b.fld from TAB b where b.fld>a.fld) and rownum=1;
of course there are better ways i'm sure, you'll just have to figure'em out.
