Oracle view in OBIEE

Hi Experts ,
We have Oracle View . There is no primary key is defined in this view. I need to join this view with some table in OBIEE physical layer.
1. I have created one opaque view with query
SELECT 'YES' PRESERVE FROM DUAL (Dummy table)
and make the join ..and report is also working fine...
So is this correct method.
2. Can we define Key at OBIEE level.(Make an alias and do self join)
If we define key at obiee level the key should be uniqe and for that we need to make all the view column as key.
please suggest..which method is good.
Thanks.
S

so can i create my key on any column and do the self join by creating alias...
I just want to give a join to my view so that obiee will not give any warning...
report is coming from view only...no fact and dimension here...view is on OLTP system

ORA-02070: Error when updating a SQL Server table thru an Oracle View

I have a SQL Server table TIMESHEET which contains a number of VARCHAR and NUMERIC columns plus a DATETIME column.
Only the DATETIME column is giving me trouble.
On the ORACLE side I have a view which selects from the SQL Server table but in order to get the SELECT to work, I had to either put a CAST or TO_DATE function call around the DATETIME field
Below is the relevant part of the 2 view definitions I have tried
create view TIMESHEET as
SELECT
"TsKeySeq" as TS_KEY_SEQ,
"EmployeeNo" as EMPLOYEE_NO,
CAST("PeriodEnding" AS DATE) as PERIOD_ENDING,
. . . (more columns - not relevant)
FROM [email protected];
An update to the view generates this message
ORA-02070: database OLEMSQLPSANTDAS6 does not support CAST in this context
create view TIMESHEET as
SELECT
"TsKeySeq" as TS_KEY_SEQ,
"EmployeeNo" as EMPLOYEE_NO,
TO_DATE("PeriodEnding") as PERIOD_ENDING,
. . . (more columns - not relevant)
FROM [email protected];
An update to the view generates this message
ORA-02070: database OLEMSQLPSANTDAS6 does not support TO_DATE in this context
If I don't include either the TO_DATE() or CAST() then I get
Select Error: ORA-28527: Heterogeneous Services datatype mapping error
ORA-02063:preceding line from OLEMSQLSANTDAS6
Does anyone have any idea how to update a SQL Server DATETIME column thru an ORACLE view?

You can't cast accross heterogenious databases and there is no need to. HSODBC treats SQL Server DATETIME column as DATE. For example, I have SQL Server table:
CREATE TABLE [Ops].[T_JobType](
     [JobType] [varchar](50) NOT NULL,
     [JobDesc] [varchar](200) NULL,
     [InsertDt] [datetime] NOT NULL CONSTRAINT [InsertDt_00000006] DEFAULT (getdate()),
     [InsertBy] [varchar](128) NOT NULL CONSTRAINT [InsertBy_00000006] DEFAULT (user_name()),
     [LastUpdated] [datetime] NOT NULL CONSTRAINT [LastUpdated_00000006] DEFAULT (getdate()),
     [LastUpdatedBy] [varchar](128) NOT NULL CONSTRAINT [LastUpdatedBy_00000006] DEFAULT (user_name()),
CONSTRAINT [T_JobType_PK] PRIMARY KEY CLUSTERED
     [JobType] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 100) ON [DATA01FG]
) ON [DATA01FG]Now on Oracle side I do:
SQL> desc "Ops"."T_JobType"@pbods
Name                                      Null?    Type
JobType                                   NOT NULL VARCHAR2(50)
JobDesc                                            VARCHAR2(200)
InsertDt                                  NOT NULL DATE
InsertBy                                  NOT NULL VARCHAR2(128)
LastUpdated                               NOT NULL DATE
LastUpdatedBy                             NOT NULL VARCHAR2(128)

Rebuilding of the InforSource of DBCONNECT to Oracle View

Hello,
following problem:
I use DB connect to an Oracle Database to an View
It works fine.
I change the View in the Oracle Database and recompile it.
I get an Error while loading with an InfoPackage.
I have to drop the regenerate the Datasource and
I must Drop ! the InfoSource and
rebuild it completly again to be able to load again !
This stemms due to the fact that BW seems to protocol the internal state of the Oracle View, like displayed in the Oracle Dictionnary views user_views, all_views
or dba_views.
This is an inacceptable BW system behaviour and impossible for day to day
business, development and much work, espescially if You develop a 12 or more
DBConnect View interfaces !
Does anybody out there know how to make BW a more pleasent thing , customize it better to avoid this burden ?
Thank You !

Hello,
in all its ok, except You change the format ( number to char or char to number etc.) or the column name of DBConnect's View or Table.
In this case You have do delete the BW Datasource and rebuild it.
It is advisable to name the DBConnect View or Table exactly as
in BW. This makes setting up of the InfoSource very easy.
Thank You

USE OF VIEWS IN OBIEE REPOSITORY

Hi Gurus,
What is the use of creating views in obiee physical layer.is it mandatory?
Could any one pls explain me.
THANKS,
SIVA

No its not mandatory, its for quick fixes where you cant ETL your data into the structures you require, failing that you cant create a view in the underlying database because you dont have permissions, or its such a simple query you think it doesnt warrant creating.
Bear in mind :
All rows have to be returned from the view, the database has more work to do,
debugging your Physical SQL gets messy and quickly un-readable.
It really is for quick fixes but in the long term I'd always try and avoid them.

How to create view object for a predefined Oracle view

Trying to create an entity object with no success,,,
I have an Oracle view(complex query in PL/SQL) that I need to encapsulate as a View Object then represent a column from this view as a '' | | linkcolumn | | ''
then get a reference of the requestParameter "p" in this case that I need to use as whereclause parameter on another view object that is part of the ListPage.jsp.
The application is basically a page of organization links that when click filters their reports as a list,
In Jdeveloper's context webBean(RowSetBrowser list [org links] to RowSetBrowser [org report list])
Can I implement this functionallity using the wizards or possibly writing custom code using the standard webBeans.

Jerry,
First, you can create an entity object based on an Oracle view. If you check the "Views" checkbox in the EO wizard, you'll see a list of database views. Then you can create a view object based on your entity object, and use it like any other view object.
As for getting the page into the format you want, I suggest you start by generating your page using the BC4J JSP wizard, then customize the generated JSP.
Thanks
Blaise

Customize Filter View in OBIEE 11g

Hi,
Is there any way to customize the filter view? My requirement is not to show formulas that are used in Analysis in the “Filter view”. All analysis that we create should go with Filter Views at the bottom and Users should not see the formulas.
Example:
Column Formula:
FILTER (sales.sales USING products.product =’Electronics’)
If I filter the above column, it shows something like this:
FILTER (sales.sales USING products.product =’Electronics’) is Prompted.
What is need to show in the filters is the Title of the column i.e. Electronics Sales.
Thanks in advance.

Query to find dependency of an oracle VIEW

Hi,
I'm using oracle 10g database.
DB name is - ORCL
ORCL DB consists two schemas - Schema1 and Schema2
I have one Oracle view called VIEW1 in Schema1.
I need to find whether Schema2 uses VIEW1 in any of the Tables,views or Programs owned by Schema2.
Is there any query available to find this one?

Business components based on Oracle views

I am trying to create business component objects in a master-detail relationship based on Oracle views rather than on the underlying tables. The wizard does not create associations or links since the views have no foreign keys. I created the associations and links myself, but I am unable to add them to the data model. I am using the beta v5.0, but I had the same problem in v3.23. Can anyone help?
Thanx in advance
null

Here are the steps I just tried with JDevi 9i Beta:
[list]
[*]SQLPLUS SCOTT/TIGER
[*]CREATE VIEW DEPT_VIEW AS SELECT * FROM DEPT;
[*]CREATE VIEW EMP_VIEW AS SELECT * FROM EMP
[*]On my workspace: Right-mouse / New / Empty Project
[*]On my new project: Right-mouse / New Business Components...
[*]Next, to the connection panel
[*]Set the connection, and next
[*]Pick a package name and next
[*]Tick the [x] Views checkbox, and select EMP_VIEW and DEPT_VIEW
[*]Uncheck the "View Objects and View Links" box, since we don't want these created automatically.
[*]Click (Finish)
[*]In navigator, select my "DeptView" entity and edit it (the view is called "DeptViewView").
[*]Click on the "Attributes" tab
[*]Select "Rowid" in the attribute list
[*]Click the (Remove) button
[*]Select the "Attribute Settings" tab, and select the "Deptno" attribute.
[*]Check the [x] Primary Key checkbox for "Deptno"
[*]Click (Ok).
[*]Repeat steps above on "EmpView" entity to remove Rowid attribute and make "Empno" attribute the primary key. (NOTE: Since views don't have constraints, we couldn't detect the primary key constraint, so we default the ROWID to be the primary key in the wizard).
[*]In navigator, select my "DeptView" entity, and right-mouse / New Association...
[*]Using the wizard I create a association based on the "Deptno" attribute, and with a 1 to many cardinality.
[*]I right-mouse on "DeptView" entity and select New Default View Object... to create the "DeptViewView" view object.
[*]I right-mouse on "EmpView" entity and select New Default View Object... to create the "EmpViewView" view object.
[*]I right-mouse on the DeptViewView view object and select New View Link...
[*]I create a new view link between DeptViewView and EmpViewView
[*]On the "Source Attributes" panel, I select the "Dept2Emp" association I created above, and click the ">" to shuttle it to the selected list.
[*]Click next and notice that by selecting the association, it automatically picked the right attributes for both sides for the view link automatically.
[*]click next, then (Finish)
[*]I right-mouse on my package and select New Application Module...
[*]On the datamodel panel, I see a tree view of "Available View Objects like this:
+ Project 3
|
+---[-] Package3
|
+---[SQL] DeptViewView
| |
| +--[SQL] EmpViewView via MyViewLink
|
+---[SQL] EmpViewView[*]I select DeptViewView in the available list and click ">" to shuttle it to the selected list in my data model
[*]In the SELECTED list, I select the DeptViewView that I just added, to make it the current view in the selected list.
[*]Back in the available list, I select the "EmpViewView via MyViewLink" and shuttled it to the selected list as a detail of the current view in the selected list.
[*]I click finish
[*]I right-mouse on my AppModule and select "Test..." to build and test my appmodule.
[*]I click (Connect) on the tester start page
[*]In the tester, I right mouse on "MyViewLink" and select "Show".

After these steps, I see data correctly.

How to load oracle views data in essbase via sql interface

How doesit work? Thanks in advanceeakp

Hi,
How are you loading, if you are loading from a SQL table you would just load a null into the database
e.g. loading data into sample basic
Measures,Period,Scenario,Market,Product,Data
Sales,Jan,Actual,Florida,100-10,10
Cogs,Jan,Actual,Florida,100-10,+NULL+

Creating Waterfall Chart view on OBIEE Answers

Hello guys
Is it possible to create waterfall Chart view on OBIEE answers?
The idea is to show the differences in number between bars at the chart.
Please let me know how it can be done
Thanks in advance
Devarasu.R

Waterfall chart is not yet defined in OBIEE, But internal Corda Pop Chart engine allows you to develop new chart types. Look for Cords Pop Chart documentation in OracleBI\corda50\docs. But you need to do a feasibility study on what you get for how much work?
