Displaying page parameter value

I have a LOV portlet that contains division names with no bind variables involved. In the same portlet region, I have a calendar component that show documents for a division.
When the user select a division name from the Lov, the onChange event calls the same page passing the division name as a url parameter. The calendar has a bind variable mapped to the page parameter division_code.
When the page redisplays, I want the default value of the LOV set equal to the page parameter value. How do I do this?
Thanks,
Ed

Hi,
Try using wwpro_api_parametes.retrieve.
wwpro_api_parameters.retrieve
This Retrieves a list of all the URL parameters (names and values) from every
portlet instance that belongs to a provider.
The names and values are returned, unchanged, into a table. If a parameter has more than one value, only the first is returned.
Any user can use this procedure.
Example:
If a URL has these parameters:
http://.......?empno=10&deptno=10&a.deptno=20a.deptno=25&a.folderid=30
Then this call:
wwpro_api_parameters.retrieve(
l_names,
l_values
Sets the following names and values:
'empno', 'deptno', 'a.deptno', 'a.deptno', 'a.folderid' in l_names
'10', '10', '20', '25', '30' in l_values
Hope this helps.
Thanks,
Sharmila

Unable to read space page parameter value throug EL

Hi All,
I have been stuck in a big problem, I have to use dynamic page template in web center space means Different template for different pages.
For this I added a new page parameter in page properties but I am not able to read any Page Parameter Properties through EL.
Now my question is how can I get Page Parameter value through EL?
I appreciate your quick response.
Thanks :)

Display Multiple Parameter Values in Specific Format

In CR XI, I have a string parameter that allows single and multiple values.
Values are Ward 1, Ward 2, Ward 3, Ward 4
Iu2019m still a newbie at Crystal and canu2019t figure out how to display the parameter values in the report header in a specific way. Join({?ward},",") works fine to show the values selected, but the format is awkward.
Would love to hear any suggestions on a formula that will display the parameter values in the header as follows:
For a single parameter value:     Ward 1
For two parameter values:     Wards 1 and 2
For three parameter values:     Wards 1, 2 and 3
If all four values are selected:     All Wards
Hope I made my question clear, and thanks in advance!

Thank you so much for your response; it does work, at least partially.Certainly is pointing me in the right direction.
Is it possible to modify the case statement to add more arguments? I tried, but it didn't work correctly, although that is likely user error.
For instance, if selecting a single value, it could any of the wards, not just Ward 1. And multiple values could be Wards 2 and 3, or Wards 1 and 4, or Wards 2, 3 and 4. There are at least a dozen different possibilities, and I need a formula or case statement to account for all those possibilities.

Display page parameter in a page

hi,
I have one page parameter and i want to display in another page using Dynamic Portlet. I used portal.wwpro_api_parameters.get_value('status_desc','a'); in <oracle>. But i wont display the value. Could please anyone help? Is there any other way to display it..?
Thanks in advance

But.....what do you want to display ?
I you want the parameter name you can try to use:
wwpro_api_parameters.get_names
get_names
function get_names(
p_reference_path in varchar2
) return owa.vc_arr
Returns a list of parameter names, given the portlet's reference path. If no names are found, an empty list is returned.
Any user can use this function.
Example:
If a URL has these parameters:
http://.......?empno=10&deptno=10&ref1.deptno=20&ref1.deptno=25&ref1.folderid=30
where 'ref1' is the reference path of the portlet instance.
Then this call:
l_names owa.vc_arr;
l_names := wwpro_api_parameters.get_names
p_reference_path => p_portlet_runtime_record.reference_path
Returns:
deptno and folderid in l_names
Parameters:
p_reference_path - a unique identifier for a portlet instance on the current page. The reference_path is passed to the portlet's show procedure in the portlet_runtime_record.
Returns:
an ordered list of parameter names for a given reference path or and empty list if no parameters were found for that reference path

Problem with Crystal Reports not displaying all parameter values

Hello,
A co-worker of mine is developing a report in Crystal version 11.5.8.826. One of the requirements from his user is that they would like to select from a list of users for applicable criteria to appear in the report. He created a parameter with a dynamic list of values, entered prompt group text, selected "existing" as the data source (and chose the corresponding field from the table). This dropped the UserID field into the "value" field in the table and linked the table to the parameter. We selected "allow multiple values" as "true" and "allow discrete values" as "true".
Here is the problem. When Crystal prompts us to select the parameters, it doesn't show all of the applicable list of users (it shows 8 out of 12 users). When we run the query in a standalone sql generating tool (Toad or Golden), we see the full list of users. Crystal Reports appears to be filtering the selection list of users for some unknown reason. We have tried changing most every option that we could find within the parameter, but no luck.
The problem definitely appears to lie within the parameter- if we run the report without the parameter, we see the full list of users. Once we add the parameter and attempt to select one or many users, the problem appears.
Any thoughts? What am I missing? Any help is appreciated.
thanks,
Noel

Display a Page Parameter

Hi Everyone,
Is there a way to simply display a page parameter in a portlet? I am able to use the 'Simple Parameter Portlet" and it works great... except there is a submit button on the bottom of it. I only want to show display a page parameter, not submit them.
I could write a java portlet to display it, but this seems like overkill. Any ideas would be greatly appreciated.
Thanks gurus!
Cory

Hi Cory,
Yes, you can display a Page Parameter in a Portlet. You just need to map the Page Parameter values to the Portlet Parameters.
You can get detailed information about the steps here :-
http://download-west.oracle.com/docs/cd/B14099_19/portal.1012/b10358/design.htm#sthref1392
I have tried the steps in Oracle Application Server Portal 10.1.2 & it works. I am not sure how to get rid of the 'Submit" button...:(

Need Help: Dynamically displaying parameter values for a procedure.

Problem Statement: Generic Code should display the parameter values dynamically by taking "package name" and "procedure name" as inputs and the values needs to be obtained from the parameters of the wrapper procedure.
Example:
a) Let us assume that there is an application package called customer.
create or replace package spec customer
as
begin
TYPE cust_in_rec_type IS RECORD
cust_id NUMBER,
,cust_name VARCHAR2(25) );
TYPE cust_role_rec_type IS RECORD
(cust_id NUMBER,
role_type VARCHAR2(20)
TYPE role_tbl_type IS TABLE OF cust_role_rec_type INDEX BY BINARY_INTEGER;
Procedure create_customer
p_code in varchar2
,p_cust_rec cust_in_rec_type
,p_cust_roles role_tbl_type
end;
b) Let us assume that we need to test the create customer procedure in the package.For that various test cases needs to be executed.
c) We have created a testing package as mentioned below.
create or replace package body customer_test
as
begin
-- signature of this wrapper is exactly same as create_customer procedure.
procedure create_customer_wrapper
p_code in varchar2
,p_cust_rec customer.cust_in_rec_type
,p_cust_roles customer.role_tbl_type
as
begin
//<<<<<---Need to display parameter values dynamically for each test case-->>>>>
Since the signature of this wrapper procedure is similar to actual app procedure, we can get all the parameter definition for this procedure using ALL_ARGUMENTS table as mentioned below.
//<<
select * from ALL_ARGUMENTS where package_name = CUSTOMER' and object_name = 'CREATE_CUSTOMER'
but the problem is there are other procedures exists inside customer package like update_customer, add_address so need to have generalized code that is independent of each procedure inside the package.
Is there any way to achieve this.
Any help is appreciated.
// >>>>
create_customer
p_code => p_code
,p_cust_rec => p_cust_rec
,p_cust_roles => p_cust_roles
end;
procedure testcase1
as
l_cust_rec customer.cust_in_rec_type ;
l_cust_roles customer.role_tbl_type;
begin
l_cust_rec.cust_id := 1;
l_cust_rec.cust_name := 'ABC';
l_cust_roles(1).cust_id := 1;
l_cust_roles(1).role_type := 'Role1';
create_customer_wrapper
p_code => 'code1'
,p_cust_rec => l_cust_rec
,p_cust_roles => l_cust_role
end;
procedure testcase2
as
l_cust_rec customer.cust_in_rec_type ;
l_cust_roles customer.role_tbl_type;
begin
l_cust_rec.cust_id := 2;
l_cust_rec.cust_name := 'DEF';
l_cust_roles(1).cust_id := 2;
l_cust_roles(1).role_type := 'Role2';
create_customer_wrapper
p_code => 'code2'
,p_cust_rec => l_cust_rec
,p_cust_roles => l_cust_role
end;
end;

Not possible to dynamically in a procedure, deal with the parameter values passed by a caller. There is no struct or interface that a procedure can use to ask the run-time to give it the value of the 1st or 2nd or n parameter.
There could perhaps be some undocumented/unsupported method - as debugging code (<i>DBMS_DEBUG</i>) is able to dynamically reference a variable (see Get_Value() function). But debugging requires a primary session (the debug session) and the target session (session being debugged).
So easy answer is no - the complex answer is.. well, complex as the basic functionality for this do exists in Oracle in its DBMS_DEBUG feature, but only from a special debug session.
The easiest way would be to generate the wrapper itself, dynamically. This allows your to generate code that displays the parameter values and add whatever other code needed into the wrapper. The following example demonstrates the basics of this approach:
SQL> -- // our application proc called FooProc
SQL> create or replace procedure FooProc( d date, n number, s varchar2 ) is

3          -- // do some stuff
4          null;

How to show a parameter value in the paper layout

Hi,
I have a paper parameter form. I need to show the value of the parameter at the top of my report as part of the title. Any ideas?
Thanks,

It should display the parameter value in the field you created in the paper layout.
Make sure you selected the source of the field.
From the property inspector of the created field go to the source property and select the parameter name from the pop-up list.

Contradictory Display of parameter shared_pool_size?

Hello All,
I want to change the value of the parameter shared_pool_size. I am on Oracle 9i and I confirm that dynamic SGA is activated.
I use brtools to change this parameter and use scope=spfile.
After I change the parameter I go back to the Display parameter menu and when I display this parameter value it shows,
Parameter value=<old value> Why?
Value in spfile = <new value>
when i give the cmd show parmeter from SQL prompt it displays <old value>. Why???
Now even if i use scope='memory' or 'both' the outputs are,
In brtools Menu,
Parameter value=<old value>
Value in spfile = <old value>
and through sql prompt -> <old value>
can someone please explain?
I understand this parameter change doesnot require a restart because Dynamic SGA is activated but even a restart of DB doesnot help.
Thanks,
Bidwan

How to get the URL parameter value when navigating from JSP Page to portal

Hi All,
I have web Dynpro application with one button, while clicking that button It will navigate to JSP page as external window. In the JSP page I have a input field and Button.
In the JSP page input field I will enter some values and press submit button, it will navigate to Portal page by passing some URL parameter with values.
Once user entering to portal by default WD page displayed, the same WD page I try to get the URL Parameter which I have passed from JSP page, but I am not able to get the URL parameter value.
If same application running in without portal, I can able to get the URL parameter values. I am getting the URL parameter by interface view default inbound plug parameter.
How do we resolve this problem?

Displaying user selected value during PFR() in th same page again.

Hi,
I have search/Results both in the same Page.
Hence initially Results(Advance table will be empty).
Once user provides search conditions and clicks 'Go'.I perform VO query which is associated with the Advanced Table.Hence Results get populated automatically in the table.
I need to display one of the search condition values as the Advanced Table header.Ex :Currency chosen (USD,Euro,INR etc)
My Issue is
I receive input conditions in the PFR().
Once I query the VO i assume that OAF invokes PR() for the page.
How can I pass the Currency unit received in PFR() to PR() to programmetically edit the Header of Advanced Table.
Thanks,
Gowtam.

Gowtam,
Set the values which you want to show as header as parameters when you are in PFR handling the search Go button request. In PR make sure to set the set the text for the header bean dynamically at each execution. If you get the parameter values, set them as header text as required and in case the parameters are null i.e. when you come to page for the 1st time, put your default text or null as required.

How to read value of page parameter from form?

I have the following in 'before displaying the form. ' in the form based on procedure.
declare
l_names OWA.vc_arr;
l_values OWA.vc_arr;
p_portlet_record portal.wwpro_api_provider.portlet_runtime_record;
BEGIN
Portal.wwpro_api_parameters.retrieve(l_names, l_values);
htp.p('Number of parameters are : '||l_names.count||'< br>');
for i in 1..l_names.count
loop
htp.p(l_names(i)||' = '||l_values(i)||'< br>');
end loop;
htp.p('Agreement'||portal.Wwpro_Api_Parameters.get_value('agreement',p_portlet_r
ecord.reference_path));
end;
Following is the output on the form:
Number of parameters are : 1< br> sessionid = 14212< br> Agreement.
Looks like the form is only getting the sessionid parameter and not getting
the other parameter from the URL.
Following is the URL for the page on which the form is places:
http://<machine_name>/portal/page?_pageid=33,36124,33_36134:33_44551&_dad=portal
&_schema=PORTAL&agreement=DG-2474/1
Can anyone tell me how I can get the value of page parameter 'agreement' in the form?
thanks,
Hiren

Hi,
It depends how you are setting your parameter also as there are different types of parameters in portal. The best is to use the page level parameters..
Please read the developers gide Section 8.3 for more details....

Retrieve All records and display in Report using CAML query in Report Builder if Parameter value is blank

Hello Experts,
i have created a report where i have one parameter field where user will pass parameter(e.g. EmpId). As per parameter record will fetched to report if no parameter is passed then it will display all records. I have done it by taking SqlServer Database as datasource.
by using Following method
Now i would like to do it by taking Sharepoint List as Datasource. For that what would be the CAML Query.
Here is my existing CAML query.
<RSSharePointList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<ListName>Employees</ListName>
<ViewFields>
<FieldRef Name="Title" />
<FieldRef Name="FirstName" />
<FieldRef Name="LastName" />
<FieldRef Name="FullName" />
<FieldRef Name="UserName" />
<FieldRef Name="Company" />
</ViewFields>
<Query>
<Where>
<Eq>
<FieldRef Name="Title" />
<Value Type="Text">
<Parameter Name="EmployeeId"/>
</Value>
</Eq>
</Where>
</Query>
</RSSharePointList>
The above code is working if i am passing an employeeId to Parameter. If nothing is passed, it is Not retrieving any record.
Please suggest
Thank you

Your problem follows the well-established pattern of using an "All" parameter filter in SSRS. There are a few approaches depending on the size of your data. The easiest one is to return all data from CAML and then filter it within SSRS, the following thread
provides some examples,
http://stackoverflow.com/questions/18203317/show-all-records-some-records-based-on-parameter-value.
Other options include passing all of the possible values within the CAML query when "All" is selected, using multiple Report Files to distinguish between both CAML queries, or to use multiple datasets with some logic to show/hide the correct one.

Display pages that reacts to different values in the drop down list.

I currently did up a simple drop down list that stores values retrieved from the database. I would like the program to display pages that reacts to the selected value without the press of any button, which means, if I select any value from the drop down list, the page will be displayed according to the value selected.
Below are the codes that I did for the retrieval of data from the database.
<%
        String username = "test";
        String password = "test";
        String thinConn = "jdbc:oracle:thin:@dbdev:1521:ORCL";
