Obiee Answers Direct database request error

Hi,
I am learning obiee 10/g and installed 10g version on my laptop.
when i tried to run the query in Answers through "direct database request"
connection pool is > "SH"."Connection Pool"
Sql statement is > Select * from Channels
When i clicked on "validate sql and retrieve columns" button i get the below error
error : Odbc driver returned an error (SQLExecDirectW).
error : [nQSError: 16001] ODBC error state: S0002 code: 942 message: [Oracle][ODBC][Ora]ORA-00942: table or view does not exist. [nQSError: 16002] Cannot obtain number of columns for the query result. (HY000)
error : SQL Issued: {call NQSGetQueryColumnInfo('EXECUTE PHYSICAL CONNECTION POOL "SH"."Connection Pool" SELECT * FROM Channels')}
What could be the issue ... Please advise
Thank You

Hi,
The channels table is in the database schema ..because i am able to drag the columns from channels table in answers and veiw the results.
when the query runs through the RPD it works fine .
but when i run the query using direct database request feature of answers...I see the error.

OBIEE Answers Direct Database Request

The issue is that I want to link two reports created using Direct Database Request. i.e. when I click on a column of Report A I should be directed to Report B with the filter passed from Report A. The issue that we are facing is that we can access the presentation variables in Report A, but are unable to pass them to Report B.
Any Idea ?
Regards,

we can access the presentation variables in Report A, but are unable to pass them to Report B.
If you are not using the prompts, How can you refer a Presentation Variable?
GOURL can be implemented to Direct Database Requests...

Direct Database Request Error: illegal number at oci

Hello, all.
In Oracle BI Answers i get an error by building an direct database request: illegal number at oci.....
The reason of error is in expression to_char((date_1-date_2)*24, '9990.99')
The error disappears if i write expression to_char((date_1-date_2)/*24*/, '9990.99')
BI doesn`t understand multiplying in SQl request?

Hi,
Couple of suggestions :
1) Run your direct database queries in a SQL editor (SQL Developer, TOAD, SQLplus) etc to confirm the query runs OK - be carefull with Toad or SQL Dev - you want to return the entire dataset, not just the first xxxxK rows these tools tend to bring back, they sometimes hide the problem 'row' which maybe is causing the error.
2) Once the error is returned via straight up SQL , maybe try the database / SQL forum as your problem I think lies there, not with the BI Server.
3) My one stop shop for Oracle date arithmetic : http://www.akadia.com/services/ora_date_time.html
4) assuming the SQL returns correctly, report back to us so we can help with OBIEE specific issues !
what time period are you trying to bring back between your date 1 and date 2 ?
Hope this helps a little,
Alastair

OBIEE 10G Direct Database Request

Hey Everybody,
I'm on OBIEE 10G in a solaris environment and I'm connected to Oracle 11.2 database. I'm having trouble getting the correct dataset returned from a Direct Database Request from a dashboard that users input data. I have the dashboard created and have all the dashboard prompts setup as prestentation variables. My DDR sql looks like this:
Select from table where Batch_ID = '11' and PID = '1234' and Reported_Date = '01011900'*
My issue is that I want the Reported Date dashboard prompt to be a optional field that user do not have to enter on the dashboard. However, if a user doesn't enter a value on the dashboard then an error is thrown because the DDR sql is expecting a value for the Reported Date.
I've tried to enter the OBIEE standard "%" as an all choices option in the database and changed the DDR sql to look like this:
Select from table where Batch_ID = '11' and PID = '1234' and Reported_Date like '%'*
However, this throws an error saying an unidentified characters has been used even though if I run this above sql query directly against the database myself it gives back the wanted dataset.
Anybody ever ran across this situation before?
Thanks,
Jeff

Direct Database Request Execution Error

Hi,
Iam working with Database Direct Request to execute a stored procedure. When I hav given the commad and clicked on 'Validate SQL and Retrieve columns' it is showing all the columns below. But when I click on "Results" tab it is giving me an error like
"Error generating view. You don't currently have the necessary privileges to execute Direct Database Requests"
I logged in to OBIEE (Web) as an 'Administrator'.
What other permissions do an Administrator need in order to resolve the above issue?

Try with Evaluate function

Syntax for Evaluate function in OBIEE
Check connection pool- properties -- there you can call your procedures

Unable to Schedule a Direct Database Request in OBIEE 11g.

Hi All,
I am trying to schedule a Report that is generated using a Direct Database Request Query.
Whenever I try to create an Alert for this specific Report it Fails to deliver.
I checked the Job Manager for this Alert. I found out that the Job has completed with an Exit Code = 2 and there was no other error description for the same.
Can we not create an alert for a Direct Database Request.
Please let me know if anyone has dealed with such an issue and if anyone has a solution for this.
Thanks in advance.
Dev.

Analyses based on direct database requests and sent out through agents work just like any other analysis in terms of content, delivery etc.
Are you sure that you're not hitting a privilege problem and that the user executing the agents isn't allowed to run direct database requests?

Error in Oracle BI EE Analytics when running a direct database request

This is in the Oracle Answers portion of the Analytics tool. When a query is entered into the Direct Database Query text box and the "Validate SQL and Retrieve Columns" button is clicked, the columns are indeed returned (which would seem to indicate that the connection pool settings are correct etc.), but when I click on the results tab it throws an error:
View Display Error
Error generating view. You don't currently have the necessary privileges to execute Direct Database Requests.
Error Details
Error Codes: OAMP2OPY:Q4NU7XSN
Invalid Handle Of 'class saw::NQWebView *' Exception
I am at a loss trying to figure this error out - clearly it is connected to the DB since it can see column names, and I was able to use the Administration tool to create a repository which Analytics can use, so why can't I directly query my database? Any help would be greatly appreciated.

It sounds like the setting has not been set to allow you to execute a direct database query.
You can do this by logging into the Presentation services as the Administrator user. Clicking on the Settings tab and then selecting the Administration option. On the Oracle BI Presentation Services Administration window select the Manage Privileges option. This brings up the Privileges Administration window, scroll down to the Answers section (listed on the left) and check the Execute Direct Database Requests privilege setting this is defaulted to let no one execute Direct SQL request. Reset the privileges such that the group that the user trying to execute the direct database request belongs to is set to be able to execute the direct database requests. This should alleviate the error that you are getting.
I hope that this helps.

"execute direct database request" option is not availavle in my OBIEE 11g

Hi All Experts,
In my OBIEE-11g there is no option available of "execute direct database request" in subject area pane.Please give the solution.
Thanks In Advance

By default, this privilege is only assigned to BI Administrator Role. I'm sure you are not under BI Administrator Role and that's the reason you can't find DDR option. Ask, you Administrator to provide your application role access to 'Execute Direct Database Analysis' & 'Edit Direct Database Analysis' under Manage Privileges > Answers.
Try using DDR very carefully...You shud understand its pros and cons

Applying Prompt on Direct Database Request in OBIEE 11g

Hi
I am creating Analysis by using 'Direct Database Request' and i am executing SQL Query to direct Database i am NOT creating Business and Presentation Model in RPD. Now i have to apply Filters on Report. any idea how i can do that?
Example:
Prompt (filter) : Year                 Employee Department
                          2011                    HR
                          2012                    IT

i want to filter by YEAR and Employee Department.
Regards
Baig

NO!!!!!!!!!!
You Direst SQL query should contain the url
ex:
SELECT COL1,COL2,
'<a href=http://obiapps:9704/analytics/saw.dll?Go&Path=/Answers&path=%2Fshared%2FAppslink%20Dashboards%2F_portal%2FAppslink%20Dashboards%2FEmployee%20Department=Navigate&P0='+BUSINESS_GROUP_NAME+' target=_new>'+BUSINESS_GROUP_NAME+'</a>
FROM TABLE
then go for the column format
Note: in MS SQL + is for concat, you might have to change based on your db.

OBIEE 11.1.1.6.8 Direct Database Request

I have created a report using direct database request and created a filters using Presentation variable as prompt
However All choices from Prompt is not capturing but for any value its working fine. Please let me know how can we do for All choices with DDR
Thanks
NK

you can't pass all the choices to direct database request because direct database and here there is no relationship with existing subject area. So only one dynamic value can pass from prompt else you can hardcode the values in the bind variable. For this please refer my link https://forums.oracle.com/thread/2562814

Conditional Formatting of a Direct Database Request Columns in OBIEE 11g

Hi All,
I need to do the conditional formatting like changing the

it in the rows of Direct Database Request.
When i check the Column properties conditinal format is disabled.

Hi Shanker,
It is a limitation, You cannot use conditional formatting in Direct Database Request

Direct database request and session variable value

Hi,
I have a problem by doing the following : idea is to have report with a list of all tables in user schema (which are not all in repository physical layer).
By clicking on the name of any, should bring answer report which is done as direct database request doing basically select * from table_clicked (this will be basically the same table with sufix _err holding error rows).
What I'm trying to do is having some kind report for error rows which can be in different tables in my database. So i had in mind to construct name of table i need , and pass it to database request through session variable. Am i doing right by doing direct database request like this :
select * from 'VALUEOF(NQ_SESSION.TestVar2)'
Is there another easyer way of doing this? I know this can be done by gourl by passing parameters but not sure how when i can't filter columns in direct database request (this can be different tables with different names of columns). I hope i didn't complicated this too much.
Thnx in adwance

Hi,
I know this is a hack, and would be much more easy to create one table with dimension and measures, but this is intended to be used with code generator, which can produce different error tables with different column names in different time: It is not conviniet for somebody to add them to repository every 5 minutes. For example : i run my workflow and for first run I have errors in table1(let us say customer table with 30 columns) and if click on the table name in some answer report, i want to see all the bad records in the table. Tomorrow after the run, there are bad records in table1 and in table2 (lets say products) so I would have choice to pick table 1 or table2 and see al the bad records in any of these tables. This means that I can not now which tables will I have tomorrow, and as it is generic, I can manually add some tables in my model, and would have to add err table also as a possibility to have error rows?
I saw post saying that you can pass parameter value by using go url functionality, by modifying configinstance file, but didn't suceed - http://gerardnico.com/wiki/dat/obiee/logical_sql/obiee_session_variable_go_url . Maybe some mistake or any better solution? I created session variable TestVar2, also modified instanceconfig.xml by adding this before </ServerInstance>
<ParamList>
<Param name="NQ_SESSION.TestVar2" source="url" nameInSource="SETVAR"/>
</ParamList>
and used go url in column formula : ''||"Physical Targets"."Physical Table"||''
Can I use @1 for using first column value?
Thnx
