Using value selected in selectOneChoice as variable for execute method

I have already created data controls for the session bean method so I can drag and drop on to the jsp. This works fine when entering the data into the input text fields but I really need the first value to come from an initial page and the second value to come from the dropdown. I just don't know how to get the value or how to connect it to the button for execution.
The method takes two values
value 1, org is passed in (how do I pass from another page? I will actually have the render for this input field set to false so it does not display)
value 2, typeId from a selectonechoice drop-down list (how do I manipulate the soc to pass the information? Currently it looks as if it is just passing the elementAt number, I need get the actual value for the item selected. Where can I retrieve it?)
I have a button ready to execute the method on the session bean which should take these values. (of course the inputvalue for the soc was not typeId but I changed it. The values for the soc are actually coming from another method performed earlier.)
This is what I have so far:
I have my input text field waiting on info to be populated from the previous page (currently I manually entered it)
I have my selectonechoice populated
A button with the execute method already set (b/c I initially used the drag-drop functionality to test my method)
Forgive me for repeating myself so much.
Thanks!

How to use a collection type of bind variable for execute dynamic statement

Hi,
We have a case where we copy selective data from Schema A To Schema B in one oracle database. The copy is achieved by using
execute immediate 'insert into '||target_schema||'.tablea select * from '||from_schema||'.table a where a.id in (select test_id from '||from_schema||'.table c);';
This works fine it takes an average of 10 seconds to copy around 14 tables. We have a requirement to bring this time to 2 seconds. One observation has been the clause
"select test_id from '||from_schema||'.table c" in the above sql statement repeats for many inserts . Thus we were thinking to bulk fetch this set of tests ids and use a bind vatiable of collection type for the execute immediate clause. Any suggestions on how to achieve it?
Thanks,
Chandana

So what? Constructing a string for a table level insert and parsing it can't possibly be a performance problem. If you were creating a string in a loop to insert rows into a table by getting the data FROM a collection - that's a problem that keeps showing up in the forums.
I'm with bravid and Nikolay on this one. First find out which side, select/insert, the problem is on.
As they said you need to provide more information about the process.
And using collections for your use case is definitely not the thing to do.
1. How many rows are we talking about?
2. Are the rows being inserted into an empty table?
3. Are you running these queries during peak production hours or in a batch windows?
Tune the SELECT if the problem is on that side.
Post an execution plan for the SELECT part of a query you think should run faster.
SET SERVEROUTPUT ON
SET AUTOTRACE TRACEONLY
SQL> select * from emp;
Execution Plan
Plan hash value: 3956160932
| Id | Operation         | Name | Rows | Bytes | Cost (%CPU)| Time     |
|   0 | SELECT STATEMENT |      |    14 |   546 |     3   (0)| 00:00:01 |
|   1 | TABLE ACCESS FULL| EMP |    14 |   546 |     3   (0)| 00:00:01 |
SQL>On the INSERT side you might be able to use bulk inserts
ALTER TABLE myTable NOLOGGING;
INSERT /*+ append */ INTO myTable . . .
ALTER TABLE myTable LOGGINGIf the insert tables are always reused you could just leave them as NOLOGGING. Since you can't recover bulk data you need to make sure to get a good backup after the loads if you need to recover the data from the logs rather than just reload it yourself.

How to use the selection profile and status profile for production order?

Hi expert,
I want to know how to use the selection profile and status profile for production order. what's the usage for these two selection profile and status profile ?
Please help me.
thanks in advance.
george.shi

Hi George,
There are are two types of statuses.One is system status and second one is user status.These statuses will tell us current situation of an order.
We can't change system statuses.But we can create our own statuses through status profile.With this profile we can control user statuses.
In this status profile,
1.We define the sequence in which user statuses can be activated,
2.We define initial statuses
3. Allow or prohibit certain business transactions.
Selection profiles are used to select the objects (say production orders) with different status combinations.We assign status profiles to selection profiles in BS42 T-Code.
Regards,
Raja.

Need a Syatem variable for Executing the report by RFC.

Hi Experts,
Need a Syatem variable for Executing the report by RFC.
what i mean to say is,i can execure the report directly ...then no issues.
But if i execute the Report by RFC ,then i should put a condition with system variable...
Please suggest me ,how can put a condition when i am executing the report through RFC.
Thanks
Babu

Hello Friend,
what I understood that you want to put some extra condition if that report is getting called from RFC...
you can use the system variable SY-CPROG....it will hold the value of the report when it is geeting executing directly...
but when it is getting executed therough RFC...it will hold that RFC name...
Thanks

Using Value in a Text Entry Box for Calculation in a Variable

I have a project where I ask the user to fill in their name in one entry box and their two-digit age in another text entry box. Later in the project, I want to ask them to think back to when they were 6 years old and how they would describe themselves at that time. (the project is on self-awareness). To make this as personable as possible, I thought it would be neat to say. "(Name Variable), think back to about (Years Since 6)years ago, when you were just about 6 years old". I am having trouble getting the "Years Since 6" variable to work, and would like to know if it is possible.
I have set up the text entry box variable as "v_age"
I have set up a variable as "v_age6" with a value of "6"
I have set up the result variable as "v_result_age6"
I have set up a standard action with a mathematical expression that reads "v_result_age6 = v_age - v_age6"
The variable output does not show on the stage in project preview mode, and I think it's because there is only one variable with an assigned value in the equation. The "v_age" variable does not have an assigned value because that is a text entry box.
Is it possible to use a value typed in from a user as a variable to do math with?
Thanks.

Welcome to the forum,
Each TEB has an associated variable, its generic name is the same as the TEB. But you'd better link your variable with the more significant name to the TEB. Have a look at this real old blog post, still valid (although maybe the screenshots are bit out of date):
http://blog.lilybiri.com/timesaving-tip-create-associated-variable-for
BTW: you didn't need to create an extra variable for the number 6. This action would have done as well:
Expression v_resultage6 = v_age - 6
How do you trigger the action, by which event?

How to use the dynamical or static variable for ESSBASE cube name?

Hi Experts,
When I import ESSBASE Cube into physical layer, the cube name from ESSBASE is created automatically, such as H_Sales.
I want to use the the static or dynamical variable for replacing the external name. So I try to create the static variable in RPD,such as cubeName, and use the following code
'VALUEOF(cubeName)' into the textbox of external name.
However, when I view the report in answer, it will generate the error message: Database VALUEOF(cubeName) does not exist.
Is it possible to implement this functionality?
Thanks..

Hi,
use <%=odiRef.getSchemaName("D")%>
D as parameter if it is the Data Schema or W if you need the schema from Work Schema
Your command will be like:
select <%=odiRef.getSchemaName("D")%>.GER_LOT_EXEC_ODI('Fluxo', 1, 'C') FROM DUAL
Works?

Using multiple select lists in ADF

Hi,
I am trying to use a multiple select list in my JSP page, and have a method in the ApplicationModule be called when the Struts action is called. I am following the example ADF tutorials, where the method is added to the ApplicationModule class, then dragged onto the Stuts Flow diagram (to associate it with an action).
I am able to create a dyna form bean for the page that contains the multi select as a type "java.lang.String[]" (string array). I am able get that values that were selected in a normal action's "execute" method. For example:
msf = (DynaActionForm) form;
String[] statusSelection = (String[]) msf.get("multSelectList");
However, I cannot seem to get the "multSelectList" values into a method in my Application Module class. The "multSelectList" is defined in my dynaFormBean as a String[] type. I am passing it in as an argument like the following....
public void setParams(String multSelectList[]) {
This results in the method not being called at all. I am not sure why. Does this have something to do with a String[] not being serializable??
However, if I just attempt to pass other types form items to the method, it works. For example:
public void setParams(String simpleCheckbox) {
Does anyone know how to use multiple select lists in conjunction with ADF?
P.S.
my multSelectList looks something like this:
<select name="multSelectList" multiple size="5">
<option value="ALL">Select All</option>
<option value="preferred">Preferred</option>
<option value="standard">Standard</option>
<option value="approved">Approved</option>
<option value="interim">Interim</option>
</select>

I got this working by changing the signature of the Application Module method to use ArrayList rather than String[], then you can marshal the Struts FormBean contents into an ArrayList to pass up.
To do this, subclass the DataAction by using "Go To Code" off of the context menu and then override the initializeMethodParameters() method:
protected void initializeMethodParameters(DataActionContext actionContext, JUCtrlActionBinding actionBinding)
 //Get the String Array from the Form Bean
 String[] selection = (String[])((DynaActionForm)actionContext.getActionForm()).get("multiSelect");
 //convert that to an ArrayList
 ArrayList selectionArr = new ArrayList( Arrays.asList(selection));
 //Add that object to the Arg List for the AM method
 ArrayList params = new ArrayList();
 params.add(selectionArr);
 actionBinding.setParams(params);
}

Using a selection option Var on a restricted list of values for a char

hi all,
i am trying to use a selection option variable in a restricted list of values in a characteristic. for example. company code has the following values:
1) GB01
2) GB02
3) GB03
4) MY01
5) SG01
and so on.....
Now, i would like to restrict the list of values into GB01, GB02 and MY01.
and based on this restricted list, i will again need a variable to do a selection option in the report.
Do you think this is possible? what will be the solution to this?
i have tried to restricted it with 2 variables but it doesnt allow that.
cheers,
willie

ADF Faces has a very small learning curve, at least
on top of learning JSF itself, - it's a JSF component
library with some extra JSF framework features, but
you can use only the bits you want. It is
proprietary to the extent that you're using some code
that isn't a standard, but we run right on top of the
JSF standard (and you can use either MyFaces or the
Sun RI), so there's not a whole lot of lock-in.Ok sounds good and I am aware of a lot of the work that Oracle has been doing. I would like though ask you some additional questions.
Could you contact me at [email protected] if it is not too much trouble.
Thanks much.

How to select several values from a user exit variable in a planning folder

Hello,
I have created a user exit variable for limiting the values only to which the user need to access.
For a simulation part, it is then necessary for him to select several values from these values (not only one, and not all)
But It seems in this case the user has only two possibilities :
- keep all the values without any restriction
- restrain the selection to only one value.
It seems possible for the user to access to a multiple choice window, but this possibility doesn't seems to work : in all tests we did, only the first value was taken into account by BPS.
If this method is not good do you know an other manner to permit the user to choice several values amongst a set of pre-selected (because the original set is too important) values ?
Thanks for your help.

Hi Mayank,
Thanks for your response, but I don't think it corresponds to my problem.
I my case, I use a user exit variable to filter some data. It seems BPS offers the possibility to the user to select several values amongts the pre-selected values presented by the user exit variable, but it doesn't work. We can use a popup in which we enters the required values, but in final, only the first value is taken into account.
I don't know if it is due to a BPS bug or if it is not a good solution in regard to BPS philosophy. In this case, the concerned caracteristic isn't in the header but in lead columns.
I must present a solution to my client next monday, so I have not enough time to open an OSS message.
An alternate solution should be interesting too.
My need is to present to a user a selection of values amongst all values from an infoobject (the user exit variable seemed to be a good solution) and the user must have the possibility to select some values amongst these as filter.
Regards

USING MULTIPLE SELECT VARIABLE IN A SQL STATEMENT

In HTMLDB, the value of the parameter of a multiple select box is colon delimited(ie P6_Name = Smith:Jones:Burke). Is there an easy way to use this parameter in a SQL statement?
Example
Select *
from names
where
Name=P6_Name
Select *
from names
where
Name IN ('Smith','Jones','Burke')
Thank you

Thank you for your response! I'm an idiot. It didn't make sense to me because your talking about a multi-select variable and I was thinking about a select-list variable. My problem is that I need to assign a list of values to one select list item.
 
For example:
 
SELECT * FROM EMPLOYEE
WHERE EMPLOYEE_TYPE IN ( :SELECT_LIST_RETURN_VALUE );
 
With the select list as
 
Display value = All Types, Some Types, One Specific Type 
Return Value = (Type1, type2, type3), (type1, type2), (type3)
 
I've just started in all of this so I'd imagine that I'm probably going about it wrong.

Using a variable for two different characteristic

Hello
I've to following situation:
1) While execuring a query in BEx Analyzer, the user should manually enter a specific key date KEY_DATE
2) Then, two InfoObjects should be restricted by using that KEY_DATE as follows
 a) InfoObject BEG_DATE <= KEY_DATE
 b) InfoObject END_DATE > KEY_DATE
So, in Query Designer I've created a variable KEY_DATE and added it to each of the above InfoObjects. Now, while executing the query I get an error: "Variable KEY_DATE is used for two different characteristics".
Is there another possibility to realize my requirements?

Hi Dear,
 create variable for that date and restrict the char. info object by that date.
-->create a variable of date char.
-->in General tab, select processing by Replacement path
-->in replacement path , offset 0 and lenght 0
-->ok
when u restrict, select value ranges and select greater than for one and less than equal for another
try and let me know if any probm...
