Can I assign a default value to a parameter like C++ ?

My question is whether I can assign a default value to a parameter in Java? Let's say : public void myMethod(int p1, int p2=3){...} Is this syntax acceptable ?
Regards,
WenBin

I don't think so (the easiest way to find out is to try), but if you want something like that, most people do it like so:
private static final int DEFAULT_P2 = 3;
public void myMethod(int p1)
myMethod(p1, DEFAULT_P2);
public void myMethod(int p1, int p2){...}Hope this helps,

How to assign the default value to search parameter

Hi Experts,
I am using search view , In this I have 5 parameter lets say Transaction Type, Partner No. etc... Now I want to assign a default value to transaction type ( lets say TA) . User should be able to see this default value in the transaction type field before pressing search button.
How can I do it?
My second problem is: I have configured this search view using configuration tool but I want to assign only one value to transaction type (i.e. user should not be able to add new row in the search criteria for the transaction type by using + sign) but in rest 4 fields he can add new row and search based on that.
Note: I am using only "Is" criteria .
Any pointer will be helpful for me
Thanks and regards,
Sandeep

Hi Sandeep,
For the default search values, here is a solution. You have to redefine the method GET_VALUE1 of the context node
For example if it is the BP search (component BP_HEAD_SEARCH) context node is your enhanced class: ZL_BP_HEAD__MAINSEARCH_CN00
METHOD get_value1.
CALL METHOD super->get_value1
    EXPORTING
      attribute_path = attribute_path
      iterator       = iterator
    RECEIVING
      value          = value.
TRY.
*     Delegate operation to selection parameter
      DATA: current TYPE REF TO if_bol_bo_property_access.
      IF iterator IS BOUND.
        current = iterator->get_current( ).
      ELSE.
        current = me->parameter_collection->get_current( ).
      ENDIF.
      IF current->get_property_as_string( iv_attr_name = 'ATTR_NAME' ) EQ 'XXX'.
        IF value IS INITIAL.
          value = 'Your default value'.
        ENDIF.
      ENDIF.
    CATCH cx_root.
ENDTRY.
ENDMETHOD.
where XXX is the name of the field.
Default value will then appear in your search field, but you are still able to modify it if you want...

Fabian

A question about assigning a default value

Hi guys, I have a question about assigning a default value to a Numeric Decision CO. This Co needs 2 parameters to compare with each other. I wanna assign para1 during runtime and para2 during design time, but I have no idea how to assign a default value to para2 during design time. Can anyone help me solve this question? Thx a lot.
BTW I`m searching an article about Time-off example`s "details". I have read several articles about time-off example, but those are not detailed enough. I wanna know about all details of COs. Can anyone forward such article to me, plz. Thx again.^^

Hi,
You can assign a default value to the parameter of a callable object.
First attach your CO to an Action.At the action level you can assign default values to the CO Parameters.
Select the action in the design time.
Select the parameters tab for that action.
Select the required paramter. At the top, you can find Default value tab, with that you can assign default value.
I think you can achieve your requirements with Business logic CO better.

Assigning a default value to a user property

Hi everyone,
do you know how can I assign a default value to a user property? It would be great if I should be able to assign it from the administration without writing any code (like profile web services...).
Thank you!
Alberto Marchiaro

Hi Alberto,
I don't think you can currently do this. In other words you can't set a default value for some object property and have it subbed in when no better value is available.
You can however create a default profile, and set values for the object properties assigned to users (You do this by going to the "Default Profiles" manager). You can then edit the "Default Profile" that is already there (or create a new one), and edit the "Properties and Names". Set the value field to whatever you'd like to be copied by default.
Once done, all new users that are created via a User Synchronization job will have this default profile. The changes will not apply to users that were previously created. If you created a new Default Profile in the Default Profiles Manager, then you need to goto the Authentication Source that you are doing your sync's from and pick which profile you'd like to use for All Groups. You can also create custom Default Profiles for various groups.
Hope this helps,

Problem using default value of report parameter 1 to validate parameter 2 passed in to report

I am having a problem with an SSRS report using the default value of report parameter 1 to validate parameter 2 passed in to report (via C#) instead of using the value of parameter 1 that is also passed into the report. Here are the
simplified details:
Using SSDT, SQL Server 2008 R2
SSRS report has 2 parameters:
P1 -- text, hidden, default value 'R1', ... front-end C# code can pass 'R2' or 'R1'
P2 -- text, allows multiple values, list of available values provided by stored procedure (sproc_list) that takes P1 value as a parameter. Hence, sproc_list either provides a list for P1 = 'R1' or P1 = 'R2'.
List for P1 = 'R1' is 'A', 'B', 'C'
List for P1 = 'R2' is 'A', 'B', 'D'
Values for P1 and P2 can be passed in via C# to the report.
The C# front-end displays 2 report choices to the user, R1 and R2, where both choices call the same RDL; but choice R1 passes in 'R1' for P1, and the choice R2 passes in 'R2' for P1.
Upon a users 1st time use of the report no parameters are passed in. Then when the user exits the report, the parameter value for P2 that was chosen is saved off to a file for R1 or R2, and used the next time the user selects the report.
Everything always works fine for report R1 since the default value for P1 is 'R1'.
When R2 is chosen and the user selects 'D' as the value for P2, runs the report, then exits, the P2 value of 'D' for R2 is saved to a file. When the user returns the next day to run report R2, 'R2' is passed for P1, and 'D' is passed for P2.
This is when the problem occurs. The value of 'D' for P2 is validated against a list generated for P2 based on the default value of 'R1' for parameter P1. Hence, SSRS considers 'D' an invalid value for P2 and blanks out the P2 parameter.
The user can then use the drop down list for P2 and choose 'D', but this defeats the purpose of saving the parameter values to be used the next time.
Why is the stored procedure that provides a list of available values for parameter P2 using the default value of 'R1' for parameter P1 instead of using the value of 'R2' passed into the report for parameter P1?

Hi Tom,
Sorry for my delay.
If I understand correctly, you have two parameter in your report. It is a couple of cascading parameter. If we have choose ‘R1’ of P1, the P2 values is A, B, C. ‘R2’ of P1, corresponding P2 values is A, B, D. What your requirement is to save the end use
select option of these two parameters.
In SSRS, if we have configure the parameter with default value. When we run the report, the parameter will fill with the default value to filter data. If we want to save the last status we are render the report, we need to update the default value of P1.
If we are query the default value from database, if possible, we can
update the database try to resolve the issue. Alternatively, we can set the dynamic default value for the parameter.
Hope this helps.

Oracle how to assign a date value in a parameter declaration

How can I assign a date value to a parameter declaration in SQL?
Here's my existing script.
CURRENT:
select distinct summary as "iCash EAD Error Summary",count(*)
from AAA.BKS_ICASH_EAD_ERRORS
where creation_date > to_date('5/26/12 8:50','mm/dd/yy HH24:MI')
group by summary
I'd like to assign the date I'm searching for into a parameter and use the parameter in my query.
GOAL:
DECLARE
pCreateDate DATE;
exec :pCreateDate := '5/26/12 8:50';
select distinct summary as "iCash EAD Error Summary",count(*)
from AAA.BKS_ICASH_EAD_ERRORS
where creation_date > to_date(:pCreateDate,'mm/dd/yy HH24:MI')
group by summary

Hi,
In SQL*Plus, you can do this:
VARIABLE     pcreatdate     VARCHAR2 (20)
EXEC           :pcreatedate := '5/26/12 8:50';
SELECT    summary          AS "iCash EAD Error Summary"
,       COUNT (*)          AS "Total Count"
FROM        aaa.bks_icash_ead_errors
WHERE       creation_date > TO_DATE (:pcreatedate, 'MM/DD/RRRR HH24:MI')
GROUP BY summary
;"GROUP BY summary" means you'll get one output row for each distinct value of summary. There's no need to SELECT DISTINCT since the GROUP BY is already making sure the rows are distinct.
There are no DATE bind variables in SQL*Plus, so you have to use a VARCHAR2.
If you do something similar in PL/SQL, then you can use a DATE variable. Make sure you don't call TO_DATE on something that's already a DATE.

Assigning a default value to a field

Hello Everyone,
       Could you please tell me how to assign a default value to a field in a transparent table, so that while creating an entry even if we don't enter the value, a default value will be assigned.
Thanks,
Anbu.

Like this
DATA: BEGIN OF itab OCCURS 0,
        field1 TYPE c VALUE 'X'
        field2 TYPE c,
      END OF itab.
append itab.
append itab.
You will have by default X set in both rows for field1.
Regards
Marcin
PS: Ooops I just noticed you meant transparent table but I wrote about internal one. As long as you maintain that table using maintenance view you can use event 05 - When Creating a New Entry and set fixed value for a field there. So whenever you create new entry it will receive that value.

How to assign a default value to a column ?

Hi
In the Object browser is it possible to modifiy a column in order to assign a defalut value to the column ?
I have a table FICHE in which I want to assign a default value 0 to a column which type is NUMBER.
Thank you for your kind answers.
Christian.

Hi Christian
For one reason or the other you can't do that using 'Create Column' or 'Modify Column'. You can only do that by issuing a SQL command : alter table fiche modify column( <column name> default 0)

How to assign a default value when there is no prompted value

Dear all,
I create a filter and it's value is relate to a prompt.If the prompt is not fill I found that all record is selected.
How did I assign a default value so that when I didn't fill some value in to the prompt and still can get the result by
the default value I set?
Thanks a lot!

Are you using dates for between or some character column?
Post your example.
Instead of between use to is equal prompts, so u will have then 2 fields one for date from a nd one for date to. Everything is the same as I wrote just repeat steps...
You must put 2 separate fields if you are using date between and you want to have default variable for both.
Column formula for the first calendar date prompt:
case when 1=2 then TIMES.TIME_ID else cast ('1.1.1900' as date) end
and for the second:
case when 1=2 then TIMES.TIME_ID else cast ('1.1.2900' as date) end
Now you set up default repository variable for both prompts.
Presentation variable you put in the set presentation variable on each prompt:
p_date_from
p_date_to
And in Answers filter will be like this:
*TIMES.TIME_ID between @{p_date_from}{VALUEOF("rv_test_date_to_char")} and @{p_date_to}{VALUEOF("rv_test_date_to_char")}*
or you can put a different default variables
*TIMES.TIME_ID between @{p_date_from}{VALUEOF("rv_test_date_to_char_from")} and @{p_date_to}{VALUEOF("rv_test_date_to_char_to")}*
I posted similar in my blog:

Is it possible to assign a DEFAULT VALUE to [%1]?

Dear All,
Let's suppose I write a code like this:
SELECT T0.Ref1 AS 'Doc Num'
FROM JDT1 T0
WHERE T0.RefDate = [%1]
When I run this query, it gives the foll. dialog box asking me to enter the Posting Date.
Query Selection Criteria
Posting Date       Equal     .........
OK   Cancel
Is it possible to make SQL assign a DEFAULT VALUE (say '31-12-10') to [%1] so that:
     If I do not type in any date and press OK, SQL will accept the default of '31-12-10' and
     If I do type in a date, say '24-07-11', and press OK, SQL will overwrite the default and use this date instead?
I use SAP B1 8.8.
Thanks
LEON LAI
Why I need this?
This is my previous thread reduced to its minimum essentials.
Is it possible to combine 2 different reports in a single Query?

Hi Floyola,
Thanks for your reply.
Your code works only if I input a date e.g 31.07.11 (31 July 2011):
Query Selection Criteria
Posting Date         31.07.11
OK   Cancel
It does not work when I leave the Posting Date field blank. It gives this error msg:
System Message
No data was found as a result of the selection criteria
OK
Maybe as a newbie I am expecting too much from SQL.
If it is too much a worry, please forget it. I have alternative solutions, for example: Instead of leaving the field blank, I can type in the fictitious date 31.12.10.
I will leave this thread open for 1 or 2 days, then close it.

Can I assign my default settings in Publish?

Hi,
Each time when we publish, we need to assign some parameters again.
For example, I need to change Flash Player Version from "Flash Player 10" (default) to "Flash Player 9"
and change eLearning output from "None" to "SCORM 2004" (Enable Quiz/reporting then choose SCORM and set Manifest).
Can I assign these default settings in Publish? (Because they don't exist in Preferences)
I suppose I can modify these default values in some external files - xml, ini, etc.
Hope somebody can suggest.
Thanks.
Joseph

Sorry. I need to mofidy my saying.
We installed CP5.5 in each standalone computer without using any external share storage.
So it's true. The setting will be preserved in same project.
However, we want to have a method to pre-set publish setting.
So whenever we create a new project, its default publish settings must be Flash Player 9 (in Flash Player version) and SCORM 2004 (in eLearning output).
Thanks.
Thanks
Joseph

Dear Friend,
Here when you have the callableSattement as ?=proc(?), the first ? is an output parameter. So you should register it as out parameter using registeroutparameter.
Then you can get the value from the outparameter using callablestatement.getXXX().
Try that way.
