Select Column using Session Variable

I have set a session variable to hold the name of a column
dependent on who the user is. Is it possible to use a session
variable to select a column in a database table? If so, how? Does
it need a where statement?
Something like this?:
<cfquery name="rsSelectColumn" datasource="Test">
SELECT Column 1, Column 2, Column 3 = Session Variable
FROM tbl_data
</cfquery>
Thanks,
Dave

I think you want to do this, if the value in the session
variable is the actual column name:
<cfquery name="rsSelectColumn" datasource="Test">
SELECT Column 1, Column 2, #Session Variable# AS Col3
FROM tbl_data
</cfquery>
this way you can call any column stored in the session
variable, and it will always be usable from the QUERY as COL3
regardless of what column you used.
If that is what you want to do - it IS that simple.
Sometimes we over think things too much.

Use Session Variable with row-wise initialization

Hello,
I use an initialization block in order to load some translations in my repository (version is 11.1.1.6.BP1) :
SQL :
SELECT CODE_KEY, STRING_VALUE FROM "TABLES" WHERE LANGUAGE_KEY= 'VALUEOF(NQ_SESSION.USERLOCALE)'
Values :
CN_INCOMING, Incoming, en
CN_OUTGOING, Outgoing, en
CN_INCOMING, Réception, fr
CN_OUTGOING, Emission, fr
etc ...
I checked the row-wise intialization.
The query is correct and returns the right values (I check in the log file ..).
So far, So good.
But when I want to use session variables in a column expression (in repository) like :
CASE WHEN "column"="xx" THEN VALUEOF(NQ_SESSION."CN_INCOMING") ELSE VALUEOF(NQ_SESSION."CN_OUTGOING") END
I got the error: [nQSError: 23006] The session variable, NQ_SESSION.CN_OUTGOING, has no value definition.
If I used the same formula directly in Answers it's working correctly.
Do I have to necessarily do this in answers or is there a way to do this in the repository.
Thanks in advance
Regards
Benjamin

Yes I already tested this point, when I don't use a row wise initialization it's working, but I don't want to create one variable for each translations that I need to use in column formula if you know what I mean.
I don't understand why we can't use this kind of variable in this context ..but if I have to create the column in my analysis, I will do that, but it's not really user friendly
Anyway thanks for your time.

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

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...

It can be manipulated if it's put into a hidden form field.

Sticky using session variables

Hello
I was wondering if it is possible to stick a session to a server using session variables (such as username) Currently I am using cookies to keep the session sticky but i also need to use the session variables.
Thanks
Donagh

Donagh,
there is absolutely no reason to use both.
If the name is more important, than use the name.
If the cookie is more important, than use the cookie.
If one is not more important than the other, then keep using the cookie.
Another way to see it is :
if the name and the cookie refer to the same server, it does not matter which one you use.
But if they point to different servers.
What do you do ?
Which information do you use to select the server ?
The name or the cookie ?
As I said, there is no reason to use both.
Unless if one is missing.
But the problem is then to make sure it is always there.
Is there any stickyness issue currently ?

Can we use session variables in BI publisher's Data Model SQL Query?

Hi Experts,
We need to implement Data level security in BI Publisher 11g.
In OBIEE we do so by using session variables, so just wanted to ask if we can use the same session variables in BI Publisher as well
ie can we include the where clause in the Data Models SQL Query like
Where ORG_ID = @{biServer.variables['NQ_SESSION.INV_ORG']}
Let me know your views on this.
PS: We are implementing EBS r12 security in BI Publisher.
Thanks

Page Specific Persistence using Session Variables

Hi, I have read a lot about using session variables to persist the ReportDocument object across page loads. This works fine if you have just one page open with one report. The problem I am having is I have a web application that makes 30 or 40 different reports available to the user. To simplify the code and make it easier to add new reports I have developed a single template aspx page that can be used to view any of the reports.
My problem is that if the user opens 2 different reports in 2 separate tabs in the browser then the session variable persistence doesn't work because the session variable is available to both tabs.
Is there a way to persist the ReportDocument object which is 'page' specific.
Thanks

Your best option is likely to have something that makes the session variable names unique. I've done such things as putting the current datetime in the url as a querystring parameter and appending that to the variable name. On each postback that querystring should persist.
You might be able to use the reportclientdocument object and serialize the report and persist through view state, haven't tried this with inproc ras though. A sample that uses the ras sdk can be found [here|http://wiki.sdn.sap.com/wiki/display/BOBJ/NETRASSDK+Samples]

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')

Need Help With Redirect That Uses Session Variable

I am new to dynamic sites, php, and developer toolbox, but I have been able to create a login site using the different form wizards fairly easily (in CS3 with Developers toolbox).
 
 I am trying to set a server behavior on a page that redirects the user to a new page if a session variable matches a recordset.
 
 I was using an extension (PHP Sessions - http://www.adobe.com/cfusion/exchange/index.cfm?event=extensionDetail&extid=681308 ) that worked great, but when I installed developers toolbox, it stopped working (get error message about runtime/MX environment).

Using session variables in Flex 2

I'm not sure if this is the correct place for this
topic...but the Flex 2 upgrade/migration forum didn't seem too
lively. So let me set up my situation and then pose the question.
In Flex 1.5, I accessed the session servlet using:
<mx:RemoteObject source="servlet" id="servlet"/>
This allowed me to store session variables such as a user
object:
var u:User = new User();
servlet.session("set", "user", u);
This allowed me to access these variables from another Flex
app:
var user:User;
servlet.session("get", "user");
How would I go about doing this in Flex 2.0? Thanks to those
who can help.

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.

How to default bind variable using session variable at run time

Hi All,
I have a requirement where all VO queries (multiple VOs) produce only records that meet a certain value.
For example, I have three tables with 3 VOs and each of them has a one-to-many relationship to another table (let's call it ref table and this table has a field called release). One of the 3 VOs is a parent/master table, and the other two are child tables. I created a VO for master table that linked to the ref table and created a view criteria using the release (use bind variable) field from the ref table. The other child tables have their own VO that has view criteria that also linked to ref table using the release field.
On the UI page, I created a query component and a table from the master table VO. I also dropped the child table VOs in a tabbed panel which partial triggered by the master table. When I ran a query for a 'release' (hint: ref table value), the table for master table was filled the correct records that meet the criteria. Unfortunately, the child tables were not correct due to the query didn't use the bind variable that filter only records for the same 'release' value as the master table.
The question is how do I 'default' or dynamically set the bind variable on the child tables based on the selection criteria from the query component. I am thinking to set a session variable from the query and use it in the bind variable in the child table, but not sure how to do it.
Any suggestion how to do it or better solution to achieve the same effect?

Hi,
How about creating a custom AMImpl method, that takes parameters as required, and set the bind variables for all the desired VOs and perform executeQuery on them.
You could expose this as client interface, and then use the method as parameter form.
Check this thread for ex.

Using Session Variable with Conditional Formatting Filter

Hi,
I'm trying to add a condition to my report in order to flag all opportunities that have a close date that is in the past. The way I'm trying to do this is by adding a condition to say when close date is less than current_date, flag the column with an image.
Issue I'm having is that the filter window within conditional format tab appears to not have the session variable option as you do when you create a filter on a column the normal way. A colleague told me to use an SQL expression, but again this option seems to be unavailable too within the conditional format tab.
Can anybody assist please?
Thanks

Create a new column and write a CASE WHEN condition like case when close date < current_date then 'Y' ELSE 'N' END.
Then on your actual date column, you can do conditional analysis based on the newly created column for values having Y then the image.
finally, you can hide the newly created column.

Alternate method to writing filter for recordset using session variable

I'm not sure if this can be done. I have a user page which I'd like to return database info based upon a userid entered on another page. So far, the session variable (userid) is captured on the user page however it is supposed to return the user's name rather than displaying the session variable.
My problem is this. Within dreamweaver, I am able to create recordsets however I cannot create a filter. The connection works. At this point, I am searching for a workaround where I can tie in the session variable to recordsets. I should make mention that whenever I update the sql statement using the recordset widget, my recordset disappears. ? At any rate, heres a sample of the code sans connection strings, etc.
<%
Dim Recordset1
Dim Recordset1_cmd
Dim Recordset1_numRows
Set Recordset1_cmd = Server.CreateObject ("ADODB.Command")
Recordset1_cmd.ActiveConnection = MM_newuniversity1_STRING
Recordset1_cmd.CommandText = "SELECT name FROM table WHERE userid = '" & Session("userid_my") & "'"
Recordset1_cmd.Prepared = true
Set Recordset1 = Recordset1_cmd.Execute
Recordset1_numRows = 0
%>
On the user page, I have a 'Welcome' and the following code
{Request.userid_my}
Any suggestions? I'm afraid I'm a newbie to asp within dreamweaver cs3.

>When I insert request.userid_my code it returns the session variable
AFAIK, session variables are not part of the request object - so I do not understand why you are referencing them this way. I would use the standard reference method : Welcome <%Response.Write(Session("username"))%>
>when I insert the recordset associated with 'name' I get an Adobe End of file error. ?
Sounds like a possible problem with your installation. You may need to try reinstalling DW. How are you "inserting" this recordset and when does the error occur?
Regarding your next post...
>select name from table_name where userid = '" & namemy & "'"
>The statement consistently returns a 'quoted string not properly terminated' error.....
The select statement you quoted is obviously not complete. If you are refering to the select in your OP:
Recordset1_cmd.CommandText = "SELECT name FROM table WHERE userid = '" & Session("userid_my") & "'"
I see nothing wrong with that syntax and the string appears to be terminated correctly. If there is a different statement causing the error, please post the entire line and include a line above and below.

How to use session variables in initialization blocks

Hello,
I want to use a session variable in a initialization block. Here is what I was doing to see this working
I created a init block called name_parameter and associated with a variable target named name_parameter_v. The init string for this block is "select 'Hello' from dual".
i created another init block name_parameter2 and associated with a variable target named name_parameter2_v. The init string is "select :name_parameter_v from dual".
I have selected name_parameter in the edit execution precedence for name_parameter2.
The result set is empty. Could you please explain why I am not able to see Hello when i test name_parameter2.
Thanks.

to obtain the value contained in a session variable this is the syntax.
select 'VALUEOF(NQ_SESSION.VARIABLE_NAME)' from dual
mind the single quotes, they are necessary
