Single Selection function on Panel

Hi,
I'm making a project with a Panel (A), inside the panel will contains some self-made components that are listed in the Panel like "Large Icon view mode" in the Window explorer.
what I want to do is to make this panel to has a single selection mode as same as JTable. I would like to let it able to reset all selection of components, and only able to select one component at every time.
Any idea I can implement this Panel A ?
Thanks

I just tried to implement the Panel to simulate the single selection.
Inside the PanelA has an ArrayList to collect each inserted components (self created child panel).
Panel A handle the selection of child objects, if one object selected, PanelA will reset other objects selection.
It looks work, but is it a good way to do ?

Copy Function with Single selection of row

I want to copy necessary Planning items in my Input ready query from period 1 to remaining periods based on variable entries. To achieve this I have created a copy planning function to copy amount entered in period 1 (variable) to range of posting period variable entries (e.g. 2 -12 or 6-12).
I have created structure for GL accounts and I want to copy from period 1 to 2 - 12 for one row at a time.
I have created WAD template, I selected in behavior section of Analysis item, single with command option and assigned Planning sequence (consisting of copy function) as command.
On execution of WAD, I select single row in my input ready query and instead of one row getting copied over to the range of posting period, all rows consisting of Planning Items with amount are getting copied over, which I am not expecting with single selection option.
How can I have only one row getting copied over?
Am I am missing something?
Your suggestions are highly appreciated.

Sachin

Hello Gregor,
Thanks for your response. I tried what you have suggested and also followed the documentation, not sure why it is not working as expected
In my variable I have characterictis such as:
Version
Fiscal Year
Fiscal Year Variant
Profit Center
In my rows:
Planning Item
Columns:
Period
Amount
In behavior I have selected Row Selection Single. I am using Button group and assigned following:
Command: Execute a Planning Function -> In Data Binding -> Selection Binding -> Characteristic -> Planning Item -> Binding Type -> Item Characteristic -> Web Item Selection -> Item Binding -> Query (Analysis Item) -> Characteristic -> Planning item.
For Variable I have defined nothing.
Do you think my settings are correct?

Tree selection (single selection model) but on 2 panels

hi..
here is my problem..
I have 2 trees each with single selection mode.
i add them to 2 scrollpanes and add these 2 scrollpanes to a split pane and divided them vertically.
When i select the tree node in the upper pane the corresponding node is displayed as the root of the tree in lower pane, so far so fine.
when i select the tree node in the lower pane the tree which was already selected in the upper pane is deselected. while i want that selection to remain..
help me to solve this..
thanx in advance..
K�vi

you can only have 1 focused component, but trees shouldn't lose selection just cuz they lose focus.... unless you have a custom cell renderer for the tree and you are using the wrong options to paint the cell selection with.

Nic, for me the iTunes window looks like this, when I connect my iPad 3:
I select the iPad in the "devices" section of the Sidebar (use: "View > Show Sidebar" if the sidebar is hidden).
Click the "Apps" tab in the "Devices" pane.
Scroll all the way down in the Devices pane to "File Sharing" "Apps" section.
Then do I click "GarageBand" to select the documents in the right panel.
Which part is different for you? Perhaps you could post a screenshot?

Diffrence b/w select single & select upto one row

hi
wat is the diffrence b/w select single & select upto one row?
deepak

Hi,
Select single has to be used with a where condition that has all the key fields:
It will always return a unique record(If a match is found).
Select upto 1 rows would get your the first record if multiple matches are found.
and select up to has to be end with endselect statements.
According to SAP Performance course the SELECT UP TO 1 ROWS is faster than SELECT SINGLE because you are not using all the primary key fields.
select single is a construct designed to read database records with primary key. In the absence of the primary key, it might end up doing a sequential search, whereas the select up to 1 rows may assume that there is no primary key supplied and will try to find most suitable index.
The best way to find out is through sql trace or runtime analysis.
Use "select up to 1 rows" only if you are sure that all the records returned will have the same value for the field(s) you are interested in. If not, you will be reading only the first record which matches the criteria, but may be the second or the third record has the value you are looking for.
The System test result showed that the variant Single * takes less time than Up to 1 rows as there is an additional level for COUNT STOP KEY for SELECT ENDSELECT UP TO 1 ROWS.
The 'SELECT SINGLE' statement selects the first row in the database that it finds that fulfils the 'WHERE' clause If this results in multiple records then only the first one will be returned and therefore may not be unique.
Mainly: to read data from
The 'SELECT .... UP TO 1 ROWS' statement is subtly different. The database selects all of the relevant records that are defined by the WHERE clause, applies any aggregate, ordering or grouping functions to them and then returns the first record of the result set.
Mainly: to check if entries exist.
When you say SELECT SINGLE, it means that you are expecting only one row to be present in the database for the condition you're going to specify in the WHERE clause. so that means, you will have to specify the primary key in your WHERE clause. Otherwise you get a warning.
SELECT UP TO 1 ROWS is used in cases where you just want to make sure that there is at least one entry in the database table which satisfies your WHERE clause. Generally, it is meant to be used for existence-check.
You may not want to really use the values returned by the SELECT statement in this case (thought this may not necessarily be so).And in each case the database optimizer may choose a different strategy to retrieve the data.
Knowing when to use SELECT SINGLE or SELECT ... UP TO 1 ROWS
A lot of people use the SELECT SINGLE statement to check for the existence of a value in a database. Other people prefer to use the 'UP TO 1 ROWS' variant of the SELECT statement.
So what's the difference between using 'SELECT SINGLE' statement as against a 'SELECT .... UP TO 1 ROWS' statement ?
If you're considering the statements
SELECT SINGLE field INTO w_field FROM table.
and
SELECT field INTO w_field FROM table UP TO 1 ROWS. ENDSELECT.
then looking at the result, not much apart from the extra ENDSELECT statement. Look at the run time and memory usage and they may be worlds apart.
Why is this ?? The answer is simple.
The 'SELECT SINGLE' statement selects the first row in the database that it finds that fulfils the 'WHERE' clause If this results in multiple records then only the first one will be returned and therefore may not be unique.
The 'SELECT .... UP TO 1 ROWS' statement is subtly different. The database selects all of the relevant records that are defined by the WHERE clause, applies any aggregate, ordering or grouping functions to them and then returns the first record of the result set.

Select Single
You need to mention all the key fields of the table.
No END SELECT required.
More performance compared to upto 1 row.
Where as UP to 1 row.
YOu can use if you do not have all the primiary key fields available.
END SELECT requeired.
Since all keys are not passing, possiblities of have other rows which satisfies the condition.
Select Statement with EndSelect is a loop, which in a single run retrieves a single Record. This Record has to be stored in a Work Area and then appended into an Internal Table.
Select Statements without EndSelect is not a loop and it retrieves the whole Record set matching the Criteria in a single shot and has to be Stored in an Internal Table Directly.
The most important thing to remember about the SELECT SINGLE is
There are several things to remember:
1) It retrieves only one row
2) It does not need an ENDSELECT statement
3) THE FULL KEY OF THE TABLE MUST BE INCLUDED IN
THE WHERE CLAUSE OF THE SELECT STATEMENT

Change Magic Trackpad move cursor, select functions

I just got a Magic Trackpad for my iMac and it's great but... it's too sensitive to my admittedly heady-handed use. Can I separate the single-finger cursor movement function from the "touch and click" selection function so I can move the cursor but need a specific (two-finger?) touch/tap for selection?

Press down on the trackpad until it clicks.
Nope, the magic trackpad doesn't do this. That's the problem.
Huh, how odd. Mine does. Did Apple change the Magic Trackpad since I bought mine? Or maybe yours is defective?
The press-down-till-click is also used in either the left or right bottom corner to activate a right-click. Chosen in the trackpad preferences. Though I've gotten used to the two-finger tap for that instead.

Selecting data from Multiple Partitions in a single select stmt.

Hi all,
My Database is very large & my tables are partitioned.
My question is:
1) If my data is spread across multiple partitions, is there any way to select data from multiple partitions in a single query?
If we dont mention partition name also it works fine, but perofmance wise it will be very slow. (Using EXPLAIN PLAN)
(Note:I dont want to make use of Union concept, i want to do it in a single select statement)
For ex:
qry1.sql:
select empno from emp_trans partition (P012000)
This above query(qry1.sql) will work fine.
qry2.sql:
select empno from emp_trans partition (P012000,P022000)
The above query(qry2.sql) will return will return the following error:
ORA-00933: SQL command not properly ended
If anybody has any solution for this, pls mail me immediately.
Thanks in advance
bye
null

All my queries are dynamically generated. All my tables are also indexed partition wise based on date field. My question is, if i want to mention multiple partition names at the time of generating my query(select), then with parformance will be good. I have refered some books, inthat what they say is to use UNION concept, i dont want to use that, instead i want in a single select statement.
Thaks for ur reply

Looking for a best query for multiple IF Else statement in a single select

Hi
I want to run multiple IF Else statements in a single select SQL, each statement is one SQL operating on the same table, what is the best way to write this select SQL query ?
If it is PL/SQL, when i get the result from the first IF statement I will skip the remaining execution, and so on... Can any one help me on this.
Thanks in advance !!

I Apologize, the information i have given might not be enough.
This is my scenario,
I am selecting set of rows from the table for the employee id. After selecting those records,
i need to go through the result list and check the condition 1, if it is met, i will return that employee record.
If that condition 1 is not met, then i need to go through the condition 2. If that is met, i will return that record.
Like wise, i have four conditions.
I am trying to achieve this in a single sql. If i am not clear, please let me know.Not fully clear yet, but the picture is better already. The thing with SQL is that you should stop thinking procedurally. Instead think in data sets.
For example if the task is:
Find all managers that work in sales.
Procedural thinking would work like this:
pseudo code
Loop over all employees that work in sales
   for each row
       check if it is a manager
           if manager
              then return record
           else
              do nothing
           end
end loopThinking in datasets will result in a different logic
pseudo code
select all employees
where department = SALES
and job = MANAGERThis advantage here is that all the "Do nothing" loops are not needed. Those are already eliminated by the database.
So what is needed to help you? Give the full picture. What is your task that you try to solve. From a business perspective.

SSRS report - A single selection dropdown list converted to text box

Hello everyone,
We created a single selection dropdown parameter (City parameter) on a report. The data in this parameter is populated using MDX query. Also, it is filtered based on selection of another single selection dropdown list (Country parameter) of a report.
The problem is when there is no cities for the selected country the dropdown list is gets converted to free type text box and user can insert city data in it. Why SSRS is not keeping it as empty dropdown list with no data?
Any help would be much appreciated.

Hello Charlie,
We developed a fresh report only with two parameters but still the dropdown control gets converted to text box in our case. We have two single selection parameters, Location and Customers. Based on selected Location the customer
dropdown gets populated.
Location Parameter Query
WITH MEMBER [Measures].[ParameterCaption] AS [Location].[Location Name].CURRENTMEMBER.MEMBER_CAPTION MEMBER [Measures].[ParameterValue] AS [Location].[Location Name].CURRENTMEMBER.UNIQUENAME MEMBER
[Measures].[ParameterLevel] AS [Location].[Location Name].CURRENTMEMBER.LEVEL.ORDINAL
SELECT {[Measures].[ParameterCaption], [Measures].[ParameterValue], [Measures].[ParameterLevel]} ON COLUMNS , [Location].[Location Name].ALLMEMBERS ON ROWS FROM [Model]
Customer Query
WITH MEMBER [Measures].[ParameterCaption] AS
[Customer].[Customer Name].CURRENTMEMBER.MEMBER_CAPTION
MEMBER [Measures].[ParameterValue] AS
[Customer].[Customer Name].CURRENTMEMBER.UNIQUENAME
MEMBER [Measures].[ParameterLevel] AS [Customer].[Customer Name].CURRENTMEMBER.LEVEL.ORDINAL
SELECT {[Measures].[ParameterCaption], [Measures].[ParameterValue], [Measures].[ParameterLevel],[Measures].[Amt]} ON COLUMNS,
nonempty([Customer].[Customer Name].ALLMEMBERS,[Measures].[Amt]) ON ROWS FROM ( SELECT ( STRTOSET(@LocationName, CONSTRAINED) ) ON COLUMNS FROM [Model])
Regarding parameter settings on General tab for both the above parameters we did not select any of the following values, all these checkboxes are empty:
Allow Blank Value ("") , Allow null value, Allow multiple values.
I think it has something related to [Measures].[Amt] that we used in customer parameter. We are now trying to take other two parameters where we would be not using the [Measures].[Amt] to filter the data. Will update you soon.

Select() function is not working properly in solaris 10.

Hi ,
We are facing an issue with select() in Solaris 10. we had written a sample program to this issue.
Program name :- sel.cpp
int main()
struct timeval sleeptime;
sleeptime.tv_sec = 60;
printf("1\n");
select(0,NULL,NULL,NULL,&sleeptime);
printf("2");
return 0;
When i run this program in Solaris 9, its printing 1 and after one minute its printing 2.
When i run this program on Solaris 10, its printing 1 and 2 without waiting for 60 seconds.
When i tried to print tv_usec, its printing as 0 in solaris 9 and some garbage values in solaris 10.
I think because of that the above select function is not working properly in solaris 10.
Why the tv_usec is not taking 0 as default values in Solaris 10?
We are using our legacy code for past 20 years. So, before going to do any changes we are trying to find why this happenig like this.
Thanks a lot.
Regards,
Srikanth.

It sounds to me that you've been lucky for 20 years then.
Local POD variables on the stack that aren't explicitly initialized can contain any value. Here's what I see in your app with dbx
(dbx) run
Running: sel
stopped in main at line 9 in file "sel.cpp"
    9      sleeptime.tv_sec = 60;
(dbx) print sleeptime
sleeptime = {
    tv_sec = -4198732
    tv_usec = 0
}That's on a Solaris 10 SPARC machine. If I try it on a Solaris 10 x86 box then I get
(dbx) print sleeptime
sleeptime = {
tv_sec = -830490588
tv_usec = 134510556
and I see the behaviour that you describe.

How to get selected record details when single selection is used in a table

Hi All,
Inside a query region I have created a table using region wizard,for this table I have added a singleSelection Item. What I want is , on selection of a particular record i want to update or view that record in a new page , for this I have added update and view icons in each row.
But I am unable to get the particular selected record
OATableBean tableBean = (OATableBean)webBean.findChildRecursive("ResultTableRN");
OASingleSelectionBean singleSelection = (OASingleSelectionBean)tableBean.getTableSelection();
For this singleSelection object I was unable to find any method which will give the value of the view attribute associated with it.
Anybody any suggestions regarding it ?
Thanks in advance,
Anant NImbalkar.

Hi Anant,
here is how you have to do it
1) you need to enable PPR on that Singl selection , by changining the Action type =fireAction.
2) define the envent , EVENT
3) define paramters for that event. This is place that gives you handle to the Attribute of VO.
So you can define paremters such
Name = PARAM1
value =${oa.EqxContactPrivEOVO1.ContactPrivilegeId}
You can define as many paramters as you can for the vo field that u wanted to have.
Now in the procesformRequest() , all you do it handle the event EVENT and get the parameters
if ("EVENT".equals(pageContext.getParameter(EVENT_PARAM)))
String accountid= pageContext.getParameter("PARAM1");
You can refer developer guide for further details.
