Session Variable in Physical Layer

Hi All,
I am trying to use session variable in Physical layer i mean in select statement like select region,revenue,year from ABC where siteid ='VALUEOF(NQ_SESSION."siteid")' but it throws a warning saying that
WARNINGS:
GLOBAL:
The repository variable, NQ_SESSION."siteid", has no value definition.
even though I gave value is zero for not exisiting site in init block but it is still throws same warning.
is there anything i am doing wrong.Please can you give ur valuable suggestions .
Thanks for ur replies!!!!!!!!1

Thanks for replying!!!!!!!
I checked it.There are no values in it even though i forced some dummy values(i.e it's everthing plain).I dont whether we can pass session variables values in Physical Layer or they can be only used in BMM Layer.
This is what i did
select 'siteid',site_id from xyz as a where upper(a.loginname)=upper(:user) union select 'siteid',0 from dual and then pass the values in physical layer
select e,r,t,,u,i from ABC where siteid ='VALUEOF(NQ_SESSION.siteid){Note:Its just example don't think about column names or tables names}
Please correct if i am doing anything wrong.
Thanks

OBIEE | Using Dynamic Session Variable in Physical Layer

Hi All,
Any idea if we can use Dynamic Session Variables (I think they are also called Repository Variables) in our physical layer. I basically need to set the value of this variable from dashboard when a link is clicked, and then use this in my SELECT query at physical layer so that OBIEE does not pull all the data from the database tables.

Christian,
Thanks for the quick response, ok we have actually moved to a different solution now, we are actually using Direct Database Request because one of our reports is supposed to be accessing direct transactional system i.e. for this report we are using OBIEE as a reporting tool. We are able to do that and even create links between different reports i.e. based on prompt in Report A filter Report B, but the scenario now is that we need to set a presentation variable from Report A when a navigation link gets clicked, because so far according to our knowledge direct SQL only allows presentation variables in its WHERE clause. So, any ideas how can we set a presentation variable when a navigation link is clicked. Thanks.

Creating filtered view on the physical layer ussing session variable USER

Hi:
I´m creating a view on the physical layer, the view needs to be created dynamically. So depending on the user (using the session variable USER) the view is created with the data a particular user is able to see.
Fisrt I imported the table and changed it´s properties to be created through a "Select Statement" so i don´t needed to change the mapping on the bussiness model layer.
The consistency check was OK but i´m not able to see data in answers, even using the Administrator user. Have anyone tried to do this? Here is my query.
Thanks
A Garcia
Select * from D_ESTRUCTURA_RH2 where Region_ID
IN
select distinct a.REGION_ID from APP_INDPERSONAL_DM.D_ESTRUCTURA_RH2 a
inner join (
select distinct b.REGION_ID from APP_INDPERSONAL_DM.D_ESTRUCTURA_RH2 b
where exists (select 1 from APP_INDPERSONAL_DM.Autorizacion a, usuarios c
where a.app_id = 1
and a.usuario_id = c.Usuario_Id
and UPPER(c.Nombre_Usuario)=UPPER(':USER')
and a.miembro_id = 'REGION_ID'
and a.operador = '='
and (b.REGION_ID = (case when valor = 'Todo' then 0 else valor end) or valor='Todo'))
) seguridad
on
a. REGION_ID = seguridad.REGION_ID
)

whay not use the same filter in the content tab of the logical table source?
check the physical sql sent to databse using web-admin-manage sessions-view log and see if there is any unexpected behavior. also run the same query in db and see iff you get the results in databse itself.

How to pass a session variable to the bussines layer?

Hello,
I am doing a management application, and I need to store the login user that make insertions on any table, and the pages does not has backing beans.
I had try to do that bindding the value field of a hidden attribute with the session variable, but it only change the value of the one. My second attempt was make an javascript function to do that on the page´s load, but it not looks like a good solution.
Someone knows a way to sent the session value to the bussines layer? O a way to access from the Bussines layer to the session?
Thanks
Tony


Hi,


Another solution (that I always use) is storing simultaneously the same data in HttpSession (in view layer) and session hashtable (in businness layer).


You can put and get these data in any businness component using following methods:



private void setToJboSession(String key, Object val){
 Hashtable userData = getDBTransaction().getSession().getUserData();
if (userData == null) {
userData = new Hashtable();
userData.put(key, val);
}


and



private Object getFromJboSession(String key){
return getDBTransaction().getSession().getUserData().get(key);
}

How to create a physical table with a session variable.

Hello,
I have been trying to accomplish accessing data multiple databases from a single rpd and single connection pool. Is there a way to do it using session variables and OBIEE stored procedures or something. If someone has anything I could read up(unless I have already googled it), it would really help me out.
Thanks.

Where is there a need to access multiple DBs using the same connection pool?
Just curious.

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

Passing Session variable of DATE data type to opaque view filter

Hi Everyone,
Can you guys please help me in passing session variable of DATE data type in RPD's physical layer 'opaque view' filter for Oracle database
I tried following syntax, syntax wise I didn't got getting any error, but at the same time this opaque view is not fetching any records as well. my session variable is "END_DATE" and its value is 1998/12/31:00:00:00(as shown in RPD session windows, datatype is DATETIME)
SELECT AMOUNT_SOLD, CHANNEL_ID, CUST_ID, PROD_ID, PROMO_ID, QUANTITY_SOLD, TIME_ID FROM SH.SALES
WHERE TIME_ID =TO_DATE( 'VALUEOF(NQ_SESSION.END_DATE)','MM/DD/YYYY')
SELECT AMOUNT_SOLD, CHANNEL_ID, CUST_ID, PROD_ID, PROMO_ID, QUANTITY_SOLD, TIME_ID FROM SH.SALES
WHERE TIME_ID = TO_DATE( 'VALUEOF(NQ_SESSION."END_DATE")','MM/DD/YYYY')
SELECT AMOUNT_SOLD, CHANNEL_ID, CUST_ID, PROD_ID, PROMO_ID, QUANTITY_SOLD, TIME_ID FROM SH.SALES
WHERE TRUNC(TIME_ID) = TO_DATE( 'VALUEOF(NQ_SESSION."END_DATE")','MM/DD/YYYY')
In past, I was able to pass a session variable into a opaque view filter using DATEOF function, but that was in DB2.
I appreciate your time and help

Finally, I got right format. here it is
to_date(substr('valueof(NQ_SESSION.END_DATE)',1,10), 'yyyy-mm-dd')
and here is the source from where I got this information

'In Between' Date Prompt to set Session Variables???

Hi
Im very new to OBIEE and was hoping someone could help me. I have a date prompt using the 'in between' operator based on a date column.
I am trying to set up a table in the Physical layer of the RPD using a stored proc (EXEC sp_name). The stored proc takes 2 input paramaters - a start data and an end date. These dates i would like to come from the in between prompt. I have set up the physical table structure to receive the results of the request.
I looked at setting a session variable but it is asking me to insert sql to set the value and i dont want to hit the database outside of the stored proc. Also, even if i have session variables i cant see how to set them to the values in the prompt when using the 'In Between' operator.
Im really very confused and i have been searching the net and the documentation for any clue.
Any help would be appreciated
Thanks

In between operator doesn't support presentation variable..
so break this into is into two prompts...and use equal to operator, then you can use them as request variables which will in turn override your session variables.
in the report use operator between and use these variables in the filter..

Session variable type in repository

Hi,
I would like to define a session variable with type INT, where in the Admin tool that I can define it?
ex: I first created a initialization block,( select a from b where id =:USER) a is a NUMBER type in the database, but it always returns an integer, when I create a session variable to contain the return of this init block, it gives me 4.0 instead of 4. I tried to use cast (a as INT) it still gives me 4.0. How can I define the session variable as INT type?
Thanks,

Hi Meli,
one thing do you want to int type or real type value in the out put..
As you said,
it gives me 4.0 instead of 4. I so, you want decimal value then why did you cast it to int?
And at last your question again
How can I define the session variable as INT type?the example you given (with 4.1) and your question is not matching..
please give clear picture what do you want?
Anyhow, Check that particular column datatype in physical layer, is that int or some other?
if you want decimal values like in database, physical column data type must be non int.
change it.. and try

Pass the filter to my physical layer view..

Hi,
My requirement is i need to pass the filter to my view (Physical Layer view).
Suppose if have a report with 4 or 5 prompts and 1 prompt am taking from that view (Physical Layer view).after running the report the query will be :
select a,b from x,(view (Physical Layer view)) where join conditions and where
prompt1='some value',prompt2='some value',prompt3='some value',prompt4='some value',prompt5='some value' (my prompts) (my prompts)
But my requirement is
select a,b from x,(view (Physical Layer view where prompt 5='some value')) where join conditions and where
prompt1='some value',prompt2='some value',prompt3='some value',prompt4='some value' (my prompts)
Hope you understand this..

Hi,
You want to pass the value from your dashboard Prompt to the physical layer view.
This can be achieved by using Request variable that you have the option of creating at the prompt level.
And then create session variable with the same name in RPD and now use that variable in the view created in the RPD physical layer in the where condition by calling the session variable.
Let me know if you need more info or if it does not work out for you.
Thanks.

Trunccolumn value while importing data to physical layer in RPD

Hi All,
While importing data from database, I want to trunc few column values so that I can put complex join, but I am not getting any link to do so.
Can anyone suggest me that if on database, if two tables are linked by outer join, than how can I restore the same join state in Physical layer while maintaining star schema.
Thanks in advance.

Hi,
I am using version 10.1.3.4.0
This query is a select type physical table in a physical layer of the RPD
select distinct project_no,project_name from cw_vertical_d where project_no = VALUEOF(NQ_SESSION."Project_Number")
NQ_SESSION."Project_Number" is a session non system variable.I am trying to set this variable through a dashboard prompt ( as a request variable ).
So when a user selects any value in the dashboard prompt then this session non system variable "Project_Number" should be set and then BI Server should fire a query with this value to pick the data from database.
But this report is failing with "*[nQSError: 23006] The session variable, NQ_SESSION."Project_Number", has no value definition*" error.
Don't know what is causing this?

Using Session Variable in the Column Level Security

My Question -
1. I created an initialization block with initialization string by calling a new session variable CTP_ID_LIST in the sql command, given appropriate database connections and when I exit out of Block, and chosen Row-wise initialization. I do not see a new session variable created under variables list. Why does this happen? Please help me on this.

Hi,
This happens when you select Row-wise Initialization.
The row-wise initialization feature allows you to create session variables dynamically and set their values when a session begins. The names and values of the session variables reside in an external database that you access through a connection pool. The variables receive their values from the initialization string that you type in the Initialization Block dialog box.
You can also use the row-wise initialization feature to initialize a variable with a list of values. You can then use the SQL IN operator to test for values in a specified list.
Example: Using the table values in the previous example, you would type the following SQL statement for the initialization string:
select 'LIST_OF_USERS', USERID
from RW_SESSION_VARS
where NAME='STATUS' and VALUE='FULL-TIME'
This SQL statement populates the variable LIST_OF_USERS with a list, separated by colons, of the values JOHN and JANE; for example, JOHN:JANE. You can then use this variable in a filter, as shown in the following WHERE clause:
where TABLE.USER_NAME = valueof(NQ_SESSION.LIST_OF_USERS)
The variable LIST_OF_USERS contains a list of values, that is, one or more values. This logical WHERE clause expands into a physical IN clause, as shown in the following statement:
where TABLE.USER_NAME in ('JOHN', 'JANE')

Dates Format in Promts using Session Variables

Hi Experts,
I have an issue in controlling date format in prompts using session variable which I am using to set default value.
By default date format is timestamp E.g '2010-12-19 12:00:00 AM'.
As per requriement(s) I customized the date format in Reports as 19-Dec-2010 and I saved it as "System Wide Default for <Date Column Name> "
So, I got desired format in Reports and Date Prompts.
Now, I need to set a default value in Date Prompt. So, in RPD I created a Session Variable which returned me date in
DD-MON-YYYY format. Using follwing SQL :
SELECT REPLACE(CONVERT(VARCHAR(11), Getdate (), 106), ' ', '-') AS [DD-Mon-YYYY]
But in reports takes this value as string and not Datetime. So i got an error message.
A datetime value was expected (received "19-Dec-2010").
If i do not use above SQL to CONVERT date then default date in prompt get displayed as timestamp format and give me desired results but Formatting looks very odd in prompt
Is this a way so I can persist the [DD-Mon-YYYY] Formatting for default value which comes using variable and still run the report.
Above problem also exist vice versa that is if i SET that session variable and pass the datetime value to server. But there i guess I can use ToDate or some Casting in RPD column expression to handle that. Tell me if i am right ?
Thanks
Saurabh

That almost works. I had to adjust the syntax to the following...and then there are other issues doing this.
select cust_no, name,'@{session.currentUser}' from customersMy write-back SQL is this:
UPDATE customers SET NAME='@{c1}',LAST_EDITED_BY='@{c2}' WHERE CUST_NO=@{c0}But I don't want to display the cust_no column to the user. So I hide it in the UI. But if I do that I get the below error during write-back. Apparently sometimes when you hide a column on a direct query (numeric maybe?) the value doesn't transfer over to the write-back. If that's the case, this won't work for me. Hmm...

Version migration, shared ssl, session variables

I'm migrating a shopping cart application from Cold Fusion
4.5 to a new server running MX 7, and have run into a weird problem
transferring session variables.
Basically, there's two sites running on one physical server.
The catalog, and then the shared ssl checkout pages. I'll call them
catalog.com and sharedssl.com.
Under 4.5, if I passed CFID & CFTOKEN in a link from
identically named applications on catalog.com to sharedssl.com, the
session and all its associated variables would transition
seamlessly forward. Under MX, this is no longer happening. The
*very first page* on sharedssl.com (the one that was directly
passed CFID & CFTOKEN) will have access to those variables, but
any subsequent pages on sharedssl.com will just throw errors.
Looking at the debugging info, it's obvious that under MX a
new CFID and CFTOKEN are being assigned when the user goes to
sharedssl.com, regardless of the session id that was passed on; as
soon as the "old" CFID & CFTOKEN aren't being explicitly
mentioned, the "new" ones take over, resulting in a completely
blank session.
Has anyone else experienced anything similar? Is there a
simple fix?
I have some ideas on how to make this work, but I'd really
like to keep this projection a "migration," and not, ie., a
"rewrite." I guess I'm wondering whether there's a configuration
checkbox I'm unaware of, or perhaps some arcane option in
cfapplication that will restore the old behavior.
Thanks for any help,
Tim
