Default parameters values

Hi, I'm using DIscoverer 4i and I noticed how the tool, after every successfull query,
remembers all the parameters' values used.
If I want to make a new query....I found automatically the parameters' values used before....
I defined, also, default values parameters, in order to show them at the beginning in the Parameter Wizard.....but they don't appear (I see always the parameters' values used in the previous query).
Is there a way to avoid to see the old parameter's values and show, instead, the default parameter's values ?
Thanks in advance
Alex

Thanks Rod, but this parameter is not present into the pref.txt file of Discoverer 4i version....
only in the 10g version...
Do you have any other idea ?

Calling a stored procedure with default parameters

Dear all,
I am trying to call a stored procedure that has not all the parameters compulsory, and indeed, there are some I am not interested in. Therefore, I would like to call the stored procedure initializing only some of the parameters but if I miss some of them, I have an SQLException thrown. Is there any way to do that?
Thanks
Marie

Hi
One way to do it is ---
By using Default Parameters you can miss few parameters while calling a procedure.
=================================================================
As the example below shows, you can initialize IN parameters to default values. That way, you can pass different numbers of actual parameters to a subprogram, accepting or overriding the default values as you please.
Moreover, you can add new formal parameters without having to change every call to the subprogram.
PROCEDURE create_dept (
new_dname VARCHAR2 DEFAULT 'TEMP',
new_loc VARCHAR2 DEFAULT 'TEMP') IS
BEGIN
INSERT INTO dept
VALUES (deptno_seq.NEXTVAL, new_dname, new_loc);
END;
If an actual parameter is not passed, the default value of its corresponding formal parameter is used.
Consider the following calls to create_dept:
create_dept;
create_dept('MARKETING');
create_dept('MARKETING', 'NEW YORK');
The first call passes no actual parameters, so both default values are used.
The second call passes one actual parameter, so the default value for new_loc is used.
The third call passes two actual parameters, so neither default value is used.
Usually, you can use positional notation to override the default values of formal parameters.
However, you cannot skip a formal parameter by leaving out its actual parameter.
For example, the following call incorrectly associates the actual parameter 'NEW YORK' with the formal parameter new_dname:
create_dept('NEW YORK'); -- incorrect
You cannot solve the problem by leaving a placeholder for the actual parameter.
For example, the following call is illegal:
create_dept(, 'NEW YORK'); -- illegal
In such cases, you must use named notation, as follows:
create_dept(new_loc => 'NEW YORK');

How to dynamically create sql statement for Defaulting Segment Values?

Hi,
Navigation:
1) Descriptive/Segments
2) Query for DFF to be modified
3) Uncheck “Freeze Flexfield Definition”
4) (B) Segments
5) Segments Summary form opens
6) (B) open - Segments form opens
Now, here I want to specify Default type as "SQL Statement" and in the default value field I want to use SQL statement with parameters (to evaluate the default value).
The parameters should be pass at runtime from the form in which we have this DFF. The parameters value should be one of the values which get evaluated at runtime in the form window.
Please suggest how we can achieve this?
Or is there any alternative to achieve this?
Thanks!!

Jason,
it is possible, though not so simple as with a report.
What you need to do is to create a pipelined function, that returns your date and count data. This pipelined function can be the base of a pseudo-table, which can be used in a select. For the pipelined function you need to define types for one row and a table to define the return-type for your function:
create or replace type calendar_row as object (date_time date, description varchar2(250));
create type calendar_table as table of calendar_row;
Then you can create the package with the function:
================================================
create or replace package dyn_calendar is
procedure set_query(i_query in varchar2);
function view_source return calendar_table pipelined;
end;
create or replace package body dyn_calendar is
v_query varchar2(100) := null;
procedure set_query(i_query in varchar2) is
begin
v_query := i_query;
end;
function view_source return calendar_table pipelined is
TYPE cursor IS REF CURSOR;
c_cal cursor;
v_date_time date := null;
v_description varchar2(100) := null;
r_cal calendar_row;
begin
open c_cal for v_query;
fetch c_cal into v_date_time, v_description;
loop
exit when c_cal%notfound;
r_cal := calendar_row(v_date_time, v_description);
pipe row(r_cal);
fetch c_cal into v_date_time, v_description;
end loop;
return;
end;
end;
================================================
Now you can set query in a PL/SL region before the calendar:
dyn_calendar.set_query(SELECT count(*), ' || :P8_SOURCE_DATE || ' FROM ' || :P8_SOURCE_TABLE || ' GROUP BY ' || :P8_SOURCE_DATE);
and you can base your calendar on the query:
select * from table(dyn_calendar(view_source))
Good luck,
Dik

Auto run report with default parameters in Viewer

Hi,
Can any one tell me if it's possible to automatically run reports in Disco Viewer with default parameter values?
For example, I have a worksheet with a parameter like 'Term like :Term Code' which has a default value of '%'.
When I open the sheet in Viewer I'm presented with the Confirmation screen with default parameter values displayed and then click OK to run report. Is there a way to skip the confirmation screen and just run the sheet with default values as soon as it's opened?
I tried using the 'Run Query Automatically' option in Query Governor preference but this results in Viewer opening the Edit Parameters screen instead of the confirmation screen.
What I'd ideally like to do is bypass both the Confirmation and Edit Parameters screen to automatically run the worksheet with default parameters as soon as it's selected.
Any thoughts appreciated,
Ien Hien

Hi,
Option 1
If the user is clicking on a URL for the report you could code the parameters directly into the URL thus, they are passed on startup. Section 13.5.2 Example 2 of the below URL provides an example:
http://download.oracle.com/docs/html/B13918_03/urlstart.htm#i1014363
Option 2 (Not Exactly what your looking for)
This would still require a user to click something but, if your passing a wildcard it should probably be considered,
If the parameter might be a wild card your better off making it an Optional Parameter which is now possible in Discoverer Plus 10.1.2. Thus, instead of passing an expensive % sign the condition will simply be ignored.
Hopefully this helps....

How to use Default parameters

Hello,
How do I use default parameters from ODP.NET. I have a proc in Oracle that shows Default? = Y when I do Describe in PL/SQL Developer. Therefore, I don't want to pass this parameter at all via ODP.NET/C# call. If I omit this parameter, I get the dreaded "Invalid number or types of parameters" error.

How to use different default parameter value for different report subscriptions

In ssrs is it possible to define different default parameter values for different subscriptions? In the following example I have a report which has two subscriptions with different start date and end date values:
Report name – Testsubscription.rdl
Subscription-1
Input parameter (default values):
start_date = first day of current Month
end_date = till date
Subscription-2
Input parameter (default values):
start_date = first day of current Quarter
end_date = till date
I know an alternative way of doing this would be to copy the rdl file with a different name but I am curious whether this can be done within a single report definition file. I am using SQL Server 2008 R2 Standard Edition.
Thanks!
spp

Hi sppdba,
As per my understanding, there is a report with two parameter: start_date and end_date, you want to configure subscription for the report, and set different default values for start date and end date. And you want to know if it is possible to achieve you
goal by using a single report definition file.
Since you are using SQL Server 2008 R2 Standard Edition, we need to achieve your goal by configuring two subscriptions for the report. For detail information, please refer to the following steps:
1. In design surface, right click start_date and open Parameter Properties dialog box.
2. In General pane, type Name and Prompt, set Data Type to Date/Time.
3. Click Available Values in left pane, select Specify Values.
4. Click Add button, in Label text box, type “First day of Current Month”, click (fx) button in Value section, then type the expression like below:
=DateSerial(Year(Now()), Month(Now()), 1)
5. Click Add button, in Label text box, type “First day of Current Quarter”, click (fx) button in Value section, then type the expression like below, then click OK.
=DateSerial(Year(Now()), (3*DatePart("q",Now()))-2, 1)
6. Right click end_date and open Parameter Properties dialog box.
7. In Available Values pane, select Specify Values.
8. Click Add button, in Label text box, type “Today”, click (fx) button in Value section, then type the expression =Today(), then click OK.
Now that the parameters are created, we need to configure subscription for the report. For detail information, please follow these steps:
1. Open Report Manager, and locate the report for which you want to create a new subscription.
2. Hover over the report, and click the drop-down arrow.
3. In the drop-down menu, click Manage. This opens the General properties page for the report.
4. Select the Subscriptions tab, and then click New Subscription.
5. Select the delivery extension and data source for the subscription.
6. Select a method of delivery, then choose report delivery options.
7. Specify conditions that cause the subscription to process and delivery to occur.
8. Set start_date to First day of Current Month, end_date to Today, then click OK.
9. Create a new subscription as step4 to 7, set start_date to First day of Current Quarter, end_date to Today, then click OK.
The following screenshots are for your reference:

Default parameters are missing in the cloned EUL

we have discoverer up and running perfectly on our existing instance - SIGMA
now we have a new instance - ALPHA,
we cloned the whole EUL from old instance(SIGMA),
IN ALPHA every thing is working fine, we have all the BA,folders and all the workbooks seem to work fine, but we have a issue with the default parameters.
the default parameters are missing from the workbooks, now this has become an big issue, because we have hundreds of reports and user want need them all with the default parameters
could somebody please help me on this issue
few questions:
when cloned does the default parameters get erased??
Does the default parameters entered in the workbook get saved anywhere in the EUL_Tables??
Could you please give me a best approach to bring in thoese default parameters??
any thoughts are highly appreciated
note: i can edit the worksheet and enter the default parameter and save the worksheet but we have got some hundreds of workbooks

Hi,
when cloned does the default parameters get erased??I would be surprised if the default parameters are erased. More likely is that they are not being used because the default value is not valid anymore or because Discoverer is trying to use the last parameter value. Check the value of the SaveLastUsedParamValue preference setting. Is this the same on Desktop, viewer and Plus?
Does the default parameters entered in the workbook get saved anywhere in the EUL_Tables??The default parameters will be save along with the workbook in the EUL5_DOCUMENTS table. The field is of type LONG RAW so you won't easily be able to see this field. You can use the workbook dump utility to check whether there are default parameters actually set up in the workbook.
Could you please give me a best approach to bring in thoese default parameters??You could try exporting and importing the workbooks into the new environment to see whether this fixes the issue.

Custom sequences or functions with default parameters

Hello!
Using the Stimulus Profile Editor, I am finding that using a sequence within a sequence to be cumbersome. This is because it requires you to declare in the main sequence, every parameter that the sub-sequence will use.
I would like to have a 'configure' sequence whose parameters are all default and do not need to be declared or passed through by every sequence that calls it. Right now, if I change one argument of the 'configure' sequence I have to go to every sequence that references it, and update the parameters and the sequence call.
Essentially, I would just like an independent subfuction that has no inputs and returns a few outputs. If the profile editor is not capable of this, what would be my next best option?
Thanks!

Hello,
You can take advantage of the new features in NIVS 2014 to help against re-defining default values for your RT Sequences. Take a look at the documentation in 2014 which explains in more detail how you can use channel references in your sequences:
What's New in NI VeriStand 2014
http://zone.ni.com/reference/en-XX/help/372846H-01/veristand/whats_new/
Variables for Reading and Writing Channels in a Real-Time Sequence

Example 1a: Reading and Writing Channels Directly from a Real-Time Sequence
http://zone.ni.com/reference/en-XX/help/372846H-01/veristand/spe_tutorial_example1a/
By using channel references, you won't have to re-set default parameters. Let me know if you have any questions.

Default parameters in R12

Hi:
I was asked to check parameters on an EBS version 12.1.3, database 11.1.0.7 on linux to see if it has all default parameters. If not what have be changed. But I dont know what are the default parameters? Is there a place I can have the default values so I can compare? Thanks and regards.

Most likely you would already have EM configure since it is default (unless you have unchecked while installing) configured with database. As I mentioned earlier, use "emctl status dbcosole" command to make sure whether EM is configured or not. Regarding SQL Developer, I am not using it but surely there will be option to administer database parameters and you will see default and changed values.

Executing Procedure with default parameters !!

hi want a small help ...
I have a
procedure p1(p1 in number default 2, p2 in number default 3)
begin
end;
When the procedure will be called without passing parameters it will execute with default parameters.
That time I want to dispay message saying
" AS paramters are not passed, procedure is being executed with foll. default parameters:
Param 1 = 2
Param 2 = 3 "
Now issue is how do I capture this condition that , the parameters are being passed and it is using default parameters ?
Thanks

The IF NOT NULL check for the parameters cannot be inside the same procedure becuase when you reach that statement, even though the parameter are not passed to this procedure, at that stage, the parameters will acquire the dfault values already assigned to them. So you never reach the else part of it.
That;s why i said, use third parameter and assign the value to this third parameter from the calling environment.
here is the short test case that might help you to understand better.

Are Default parameters required to be inputted when proc is called?

Hi,
I wanted to add default parameters to my proc (as below). I was wondering if, Default parameters required to be inputted when I call the proc? For example:
CREATE OR REPLACE PROCEDURE P2 (p_Min in number default := 0,
p_Max in number default := 0)
IS
BEGIN
P1('Select * from emp');
END P2;
Where P1 would have 2 default parameters, like this:
Create PROCEDURE P1 (p_Query in varchar2,
p_Min in number default := 0,
p_Max in number default := 0) IS (etc.) ...
Otherwise, is it possible to have optional parameters in Oracle 8i/9i? If so, can you tell me how I could do it?
Thanks in advance.
Sincerely,
Nikhil Kulkarni

Default parameter are NOT required to be inputted. You just have to careful when using more than on defaulted parameter, since you cannot skip the first defaulted parameter only, unless you use the named assignment of the parameters.
Anyway you MUST NOT pass 'null', since null is a legal value it will not be replaced by a default value! To prevent passing NULL to a procedure you can constrain the parameter.

Default Parameters are no longer default

Post Author: debmilner
CA Forum: Migration to XI R2
We used both 8.5 and version 9 to create several hundred reports, most with default parameters for the users. With Crystal 11, the parameters are still availble, however they are no longer defaults, the user must select. Since 11 does support default parameters (we are currently editing these several hundred reports to set the old default into the new default parameters field), is there an easier way than editing each report?

Hi Ike,
it's not a question of syntax. I used the ampersand for sure.
the problem is the value for the lexical param at runtime. If I use the libs of patch 8488119 the ORA-ErrMessage is returned, if I use the default libs everything works as expected...

Crystal Reports 9 and SQL Server 2005 default parameter values

We're using Crystal Reports 9 and upgraded from SQL Server 2000 to SQL Server 2005.
I'm noticing a very weird problem which I wonder if anyone else has experienced (and hopefully found a resolution for). It appears that in using Crystal with SQL Server 2005 stored procedures, if we have default parameter values in the stored procedures, the default parameter values get completely ignored if you pass in a NULL value from Crystal!
For example, if you have a stored procedure that begins like this:
ALTER Procedure [dbo].[StoredProcedure]
@Param1 VarChar(200) = '',
@Param2 VarChar(200) = ''
AS ...
both @Param1 and @Param2 have a default value of an empty string, and therefore should become empty strings if nothing (NULL values) gets passed in for them.
But, like I said, what I'm finding is that with Crystal calling the stored procedure with NULL @Param1 and @Param2 values, they never become empty strings, but rather remain as NULLs.
This was never a problem with SQL 2000.
Very perplexing. Anyone else every experience this?
Thank you.

Please ignore my earlier post -- answered my own question.
NULL parameter values do not get replaced by default values in SQL -- that is normal behavior in both SQL 2000 and SQL 2005. Just goes to show, that no many how many years programming experience you have, you can still get tripped up sometimes : (

How to hide dynamic parameters values in the URL with Reports 6i

Hi,
I want to know a way of hiding the parameters values when asking for a report through the web.
Now I'm using the Reports 3.0.5.8 with a Cartridge defined in the Oracle Web Application Server 3.0.1.0.1. When you ask for a report with the parameters DESTYPE = cache and DESFORMAT = pdf, it is fully generated and in the Address or Location box of the browser, you can see http://webserver/cache/report.pdf (where cache is the virtual directory defined in the OWAS in which the .pdfs are cached). So, users cant see the Url used to generate the report.
Im trying to upgrade this configuration to Reports 6i with Cgi in a web server. I generate reports with no problems. The problem I have is I cant find how to hide the parameters values as before. I mean, when I ask for a report, once its generated I can see http://webserver/cgi-bin/rwcgi60.exe?server=ServerName&report=report.rdf&userid=user/pass@connection&destype=cache&desformat=pdf&P1=value1&P2=value2 in the Location box. It allows user to ask for another report changing the values of the parameters. I use these parameters to execute some query written in the Data Model. For example, imagine that the P1 represents the company id, the user (that is supposed to see only data of its company) can change this id, ask for a new report and see data of another company.
Ive already tried to use the key mapping option, but its not useful to me because the parameters values are dynamic and its impossible to define different entries in the cgicmd.dat for each possible value. The option of loading the parameter form before running a report is not useful to me either, because there exists specific screens for this purpose.
Is there any solution?
Thank you.
Marma Bonfiglio.

Hi Rakesh,
I am using BI 7.0
The last option I have is 'Hide' for 'Calculate single values as' .
I have the below options for 'Calculate single values as'
1. Normalise according to Next group level Resul.
2. Normalize according to Overall Result
3. Rank number
4.Olympic Rank Number
5.Maximum
6. Minimum
7.Counter for all detailed values
8.Counter for all detailed values that are non zero
9.Moving average
10.Moving average That is Not zero ,null or Error
11. Hide.
So could you please tell me where i can find 'suppress result' option for the keyfigure .
Many thanks

Default search value for Query By Example Report

Is there any way I can add the wildcard % as a default search value for text fields in the customization screen for a QBE report? The aim is to relieve the user from knowing that you have to input the wildcard % in the search field.
Also, Is there a way to change the label of the standard 'Close' button, which is a bit misleading as it actually takes you back to the report customisation window?
Cheers,
Arnt

Hi,
You can give default values for bind variables in sql report and not for QBE reports. Also it is not possible to remove the close button.
Thanks,
Sharmila
