Cube is Selecting 34 Rows, Why ?
I am not understanding the functionalilty of Cube.
Can any one define it ?
Thanks in Advance...

Hi,
With cube, you create subtotals in different dimension. Your example does not make sense for cube, since ename is unique for all departments.
Look at this. Also note the "GROUPING" function, which distinguish pure null values and null because of grouping (giving 1).
Kind regards

Hi Riedelme,
Thanks for your reply. Further to your reply I go through Group By functionality. I tried the different ways and found the solution. I have to use
GROUP BY GROUPING SETS(con.site_code, (con.site_code, con.id, con.property_id, con.ctyp_code, con.crea_code, con.start_date, con.target_exchange_date, con.target_completion_date, con.empl_id, con.sold_by), ())But now my worry is what happens if number of column grows, say, 35. There should be some way of writing good query. Would it be possible using Analytic Function.
Experts please respond..

How to rollup cube data in Process chain?

I have loaded data into a cube, and when i look at the technical status it is green but there is nothing in the "request for reporting available"box. I went to Rollup Tab and manually execute the request. It worked.
But is there anyway that I can add a process type to do it automatically? I saw there are three process type related to Rollup, which one should I use?
1. Initial Fill of New Aggregates
2. Roll Up of Filled Aggregates/BIA Indexes (what does this mean?)
3. initial Activation and Filling of BIA Indexes
Thank you!

Dear experts,
We have the following problem: for certain figures we have on ODS level 2 daily updates: one at night and one at noon. During the week at noon we only load from the ODS into the Cubes only that data that is entered the same day (selection on CPU-Date in the InfoPackage). After loading the data at night we load the data which was entered the previous day (selection on CPU-Date in the InfoPackage). In this process we have a step in the process chain that deletes in the overlapping request of the previous day (which was loaded at noon).
Our Process Chain for loading the data from ODS into the cubes looks as following:
Delete Indexes of the cubes -> Load data from ODS into Cubes -> Generate Cube Indexes -> Delete overlapping Requests in InfoCubes
After filling the BIA-Indexes on this cube, the process chain gives an error message at the stage where the overlapping request should be deleted. The error messages says:
Uncaught Exception: Keyfigure is of type Float.
To solve this error at the moment we manually delete the BIA Indexes, delete the overlapping requests and fill the BIA Indexes again. Since the functions 'delete BIA Index' and 'Fill BIA Index' is not available in RSPC we can not do this automatically in the process chain.
I also tried like above mentioned taking the step 'roll up filled BIA Indexes' into the process chain, but the check of the process chain creates a message stating that i cannot do this when in the same process chain the steps 'Delete Indexes of the Cube' and 'generate Indexes of the cubes' are included.
Does anybody know a solution how i can delete overlapping requests in a process chain with filled BIA Indexes.
Many thanks in advance for your kind reply.
Best regards,
Ilja Dekeyser

To Rick Post about cross-tabulation, rollup, cube

Rick,
One of the systems that I have access to has just been upgraded to Oracle8i Enterprise Edition Release 8.1.6.3.0 and SQL*Plus: Release 8.0.6.0.0. So, after doing many things the hard way for a long time, I am just beginning to experiment with some of the new features that I have been reading about, like cross-tabulation with rollup and cube in the group by clause.
In the four posts listed below, where I provided solutions using decode, you have said that the desired cross-tabular result could be achieved using rollup and cube in the group by clause, but you have not provided any sample code. I have read the documentation, but am still unable to figure out how to achieve the same results. I am not receiving any error messages; I am just not figuring out how to achieve the same results. Would you please do me the favor of providing the code using rollup and cube that will produce the same results as the code I have offered, for any of the posts below?

Dear Raju,
1) Does it mean parent level members will be calculated every time it is retrieved from BPC.
2) by "user hierarchy in Bex", does it mean to "Activate Hierarchy display in Query Designer?
or u mean select the hierarchy tree when building query as shown below?
Thanks for your help.

{code}

Thanks in advance
Here's how it works.
Since the GROUP BY clause includes department_id (not modified by ROLLUP or CUBE), every row of the result set will be limited to a specific department_id.
Since the GROUP BY clause includes ROLLUP (job_id). some rows of the result set will represent a specific job_id, and some rows will be Super-Aggregate rows, representing all job_ids at the same time.
Since the GROUP BY clause includes CUBE (manager_id). some rows of the result set will represent a specific manage_id, and some rows will be super-aggregates, representing all manager_ids at the same time. (When there is only 1 expression inside the parentheses, CUBE means the same thing as ROLLUP).
Here's how it can be simplified:
GROUP BY department_id
,         CUBE (job_id, manager_id)
Here's why:
Since ROLLUP (x) means the same thing as CUBE (x) - when x is a single expression - then what you posted is equivalent to
GROUP BY department_id
,         CUBE (job_id)
,         CUBE (manager_id)
and
GROUP BY ...
          CUBE (x)
,         CUBE (y)
is just a longer way of saying
GROUP BY ...
          CUBE (x, y)
To understand this better, do some experiments yourself. Try different combinations of ROLLUP and CUBE, and see what results they produce.
DO NOT use the hr.employees table for your experiments; it has far too many groups for anyone to understand. Also, department_id and manager_id can be NULL, so it's hard to tell super-aggregate rows from normal aggregate rows. Even scott.emp is more complicated than necessary. I suggest you make your own table, like this:
CREATE TABLE simp_emp AS
SELECT ename
,       deptno
,       job
,       CASE
            WHEN job IN ('MANAGER', 'PRESIDENT')
            THEN 'NO'
            ELSE 'YES'
        END                            AS unionized
,       EXTRACT (YEAR FROM hiredate)   AS hireyear
,       sal
FROM    scott.emp
In this table, there are only 2 possible values for unionized, 3 values for deptno, and 4 values for hireyear, and none of those colums are ever NULL.

ROLLUP AND CUBE OPERATORS IN ORACLE 8I

제품 : PL/SQL
작성날짜 : 2000-06-29
========================================
ROLLUP AND CUBE OPERATORS IN ORACLE 8I
========================================
PURPOSE
ROLLUP 과 CUBE Operator에 대해 설명하고자 한다.
Explanation
ROLLUP operator는 SELECT문의 GROUP BY절에 사용된다.
SELECT절에 ROLLUP 을 사용함으로써 'regular rows'(보통의 select된 data)와
'super-aggregate rows'(총계)을 구할 수 있다. 기존에는 select ... union select
를 이용해 구사해야 했었던 것이다. 'super-aggregate rows'는 'sub-total'
(중간 Total, 즉 소계)을 포함한다.
CUBE operator는 Cross-tab에 대한 Summary를 추출하는데 사용된다. 모든 가능한
dimension에 대한 total을 나타낸다. 즉 ROLLUP에 의해 나타내어지는 item total값과
column total값을 나타낸다.
NULL값은 모든 값에 대한 super-aggregate 을 나타낸다. GROUPING() function은
모든 값에 대한 set을 나타내는 null값과 column의 null값과 구별하는데 쓰여진다.
GROUPING() function은 GROUP BY절에서 반드시 표현되어야 한다. GROUPING()은 모든
값의 set을 표현합에 있어서 null이면 1을 아니면 0을 return한다.
ROLLUP과 CUBE는 CREATE MATERIALIZED VIEW에서 사용되어 질수 있다.
Example
아래와 같이 테스트에 쓰여질 table과 data을 만든다.
create table test_roll
(YEAR NUMBER(4),
REGION CHAR(7),
DEPT CHAR(2),
PROFIT NUMBER );
insert into test_roll values (1995 ,'West' , 'A1' , 100);
insert into test_roll values (1995 ,'West' , 'A2' , 100);
insert into test_roll values (1996 ,'West' , 'A1' , 100);
insert into test_roll values (1996 ,'West' , 'A2' , 100);
insert into test_roll values (1995 ,'Central' ,'A1' , 100);
insert into test_roll values (1995 ,'East' , 'A1' , 100);
insert into test_roll values (1995 ,'East' , 'A2' , 100);
SQL> select * from test_roll;

1995 West A2 100
1996 West A1 100
1996 West A2 100
1995 Central A1 100
1995 East A1 100

1995 500 5
1996 West 200 2
1996 200 2

위의 내용을 tabular로 나타내어 보면 쉽게 알 수 있다.
Year Central(A1+A2) East(A1+A2) West(A1+A2)
1995 (100+NULL) (100+100) (100+100) 500
1996 (NULL+NULL) (NULL+NULL) (100+100) 200
700
예제 2: ROLLUP and GROUPING()
SQL> select year, region, sum(profit),
grouping(year) "Y", grouping(region) "R"
from test_roll
group by rollup (year, region);
YEAR REGION SUM(PROFIT) Y R

1995 West 200 0 0
1995 500 0 1
1996 West 200 0 0
1996 200 0 1
700 1 1
7 rows selected.
참고) null값이 모든 값의 set에 대한 표현으로 나타내어지면 GROUPING function은
super-aggregate row에 대해 1을 return한다.

HOW TO USE ROLLUP AND CUBE OPERATORS IN PL/SQL
===============================================
Release 8.1.5 PL/SQL에서는 CUBE, ROLLUP 이 지원되지 않는다. 8i에서는 DBMS_SQL
package을 이용하여 dynamic SQL로 구현하는 방법이 workaround로 제시된다.
Ordacle8i에서는 PL/SQL block에 SQL절을 직접적으로 위치시키는 Native Dynamic SQL
(참고 bul#11721)을 지원한다.
Native Dynamic SQL을 사용하기 위해서는 COMPATIBLE 이 8.1.0 또는 그 보다 높아야
한다.

Hello,
As previously posted you should use export and import utilities.
To execute exp or imp statements you have just to open a command line interface, for instance,
a DOS box on Windows.
So you don't have to use SQL*Plus or TOAD.
About export/import you may care on the mode, to export a single or a list of Tables the Table mode
is enough.
Please, find here an example to begin:
http://wiki.oracle.com/page/Oracle+export+and+import+
Hope this help.
Best regards,

Roll up command and CUBE command

Please anyone explain me what is the use of ROLLUP and CUBE command in SQL and which situations it will be using.

Rollup and cube, both of these will be helpfull in aggregate function along with group by.
Roll up will results in data along with their summation.
and Cube results in summation of all possible combination.
It will be help when creating reports and some analytical data.
Below is an article which give further more explanation
http://www.oracle-base.com/articles/misc/rollup-cube-grouping-functions-and-grouping-sets.php

How use Group By Rollup in BIP ?

Hy everybody ,
I create a dataset with this query :
SELECT cntr.country_region "Region" , cntr.country_name "Pay ", Round(AVG(s.quantity_sold * s.amount_sold ),2) "Moyenne Des Ventes"
FROM customers c inner join sales s
on c.cust_id = s.cust_id
inner join countries cntr
on c.country_id = cntr.country_id
group by rollup (cntr.country_region,cntr.country_name )
It's ok in ad-hoc mode , it's ok when i generate sample data , but when i want to create my Report : I use "Data Table" and for the "Moyenne Des Ventes" column , i have no data.
Someone can help me ?

"ROLLUP", "CUBE", "GROUPING SETS" actually I used for ad-hoc reporting only on text based tools. Though in report development tools you can easily generate sub-totals I think you can use different queries.

How to underline a row in report...

Hi,
I have a report with 3 text fields.
I need to underline every row of the report and have a problem with that.
Why?... well I will try to explain the problem.
for example:
I draw a line in the bottom of the repeating frame where the field are.
The field1 expands through 2 rows, field2 through 3 rows and field 4 through 4 rows.
...and the problem is: when I run the report he draws the line under the 1st row of first record because the first field is long only one row. That means that he draws the line over the values of the the field2 and field3 and they are not underlined they are crosslined ( hope this is a rigth word for that ).
He draws the line under the first field no matter how long are the other field.
If the first field is longer than the other two that he draws it OK, but if not that he crossline the other values.
Hope I explained my problem in understandable way...
So if somebody could help me or give me a hint...
regards,
Mzz

In need help: Analytic Report with Group by

Good morning,
I am trying to create a report with subtotal and grand total, which of couse goes to the group by clause, with rollup, cube, grouping... etc. I'd like to use rollup, then some columns in the Select list have to be put into the Group By clause, which is not supposed to be. So I had to use one of SUM, AVG, MIN and MAX functions, to make those columns as *aggregated, which is wrong.
Another alternative I tried is to use Cube and Grouping_id to be the filter. However, that is still very cumbentsome and error-prone, also the order of the display is absolutely out of control.
I am trying hard to stick to the first option of using the Rollup, since the result is very close to what I want, but avoid the usage of aggregation functions. For example, if I want to display column A, which should not be grouped. Other than using those aggregation functions, what I can do?
Thanks in advance.

Luc,
this is a simple and a good reference for analytic functions:
http://www.orafaq.com/node/55
It takes some time to understand how they work and also it takes some time to understand how to utilize them. I have solved some issues in reporting using them, avoiding the overkill of aggregates.

How to generate a row in report to compute total?

Hi:
I need help to generate a report. In an accounting report, I need to make sum for each client regarding outstanding balance. The format of report is following:
invoice#, invoice date, invoice amount, paid amount paid date, write off, outstanding balance
Client Name: Baker Express / Debtor Name: Kurt Weiss inc.
137308001, 04/18/2012, 438.07, 537.07, 06/05/2012, , (99)
137308002, 04/18/2012, 100, 90, 06/05/2012, 10,
client Total: total payment:627.07, total outstanding balance: (99)
another client and debtor pair
My question is how to generate total payment and total outstanding balancefor every pair of client and debtor. And there are multiple pairs. I tried to use group by, but how can I display every invoice tuple as well in the report?
Any help would be appreciated.

Dimension declaration. Why do we need it?

Hey, Oracle data warehouse gurus.
It should be an easy question for you.
Why do we need to declare dimension on the top of the dimension table (CREATE DIMENTION dimension_name ...)?
It seems to me that many functions such as rollup, cube and the like do not need this dimension metadata.
I am using Crystal Holos OLAP server to do data mining and reporting and again this tool (at least version 7.5) does not use dimension metadata. I suppose that some OLAP servers do.
Thanks in advance for your answer.
Best Regards
Vadim

Hello Rajsan Madhavarajan
Query as a Web Service (QaaWS) is a SAP Business Objects (BOBJ) client-side tool that allows users to create and publish Web Services that can be made available over the Web. Once these web services are created and published, they can be consumed like any other standard Web Service in software applications including Xcelsius and Crystal Reports. But first we have to understand what exactly is a Web Service.
Web Service
A Web Service is a software system that supports interoperable interaction over a network from one computer or machine to another but is more commonly defined as a client and a server communicating data over the Web using the HTTP Protocol. Using Web Services along with Business Objects allows a live connection of data to be used in applications such as Xcelsius and Crystal Reports through a semantic layer called a Universe.
Query as a Web Service (QaaWS)
The two main components in QaaWS are the Client Tool and the Server. The QaaWS Client Tool gives the end user an easy to use wizard that allows them to create Universe queries and publish them as Web Services. Once the QaaWS is published, any user can securely access the data that the Web Service contains as long as they have access to that server. Have a look on image below that shows the information flow to and from the server via the client.
Advantages to QaaWS:
Very easy to use and intuitive interface Familiar look and feel for people who have used Web Intelligence
Leverages existing Business Objects Universes Shares metadata with Web Intelligence, Desktop Intelligence and Crystal Reports
Maintains Business Objects Enterprise Security
Allows live data feeds to be incorporated into Xcelsius Dashboards and Crystal Reports

RollUp & Cube.
