Filtering Unique values in the Hash table

Hi Friends,
Could you please tell me I want to Filtering the values in the Hash table.The Values are our own objects.
E.G
class Emp
private String EmpID=null;
public void setEmpId(String Id)
EmpId=id;
public void getEmpId()
return this.EmpId;
public static void main(String[] args)
Hashtable hastab=new Hashtable();
Emp e1=new Emp();
e1.setEmpId("A");
Emp e2=new Emp();
e2.setEmpId("B");
Emp e3=new Emp();
e3.setEmpId("A");
Emp e4=new Emp();
e4.setEmpId("C");
Emp e5=new Emp();
e5.setEmpId("A");
hastab.put("1",e1);
hastab.put("2",e2);
hastab.put("3",e3);
hastab.put("4",e4);
hastab.put("5",e5);
I want to filter the duplicate values in the Hashtable.
Thanks in Advance

Could you please tell me how i will Filter duplicate
valus inside the objectI'm sorry, but I can't read the future.

WPF UI running in seperate runspace - able to set/get controls via synchronized hash table, but referencing the control via the hash table from within an event handler causes both runspaces to hang.

I am trying to build a proof of concept where a WPF form is hosted in a seperate runspace and updates are handled from the primary shell/runspace. I have had some success thanks to a great article by Boe Prox, but I am having an issue I wanted to open up
to see if anyone had a suggestion.
My goals are as follows:
1.) Set control properties from the primary runspace (Completed)
2.) Get control properties from the primary runspace (Completed)
3.) Respond to WPF form events in the UI runspace from the primary runspace (Kind of broken).
I have the ability to read/write values to the form, but I am having difficulty with events. Specifically, I can fire and handle events, but the minute I try to reference the $SyncHash from within the event it appears to cause a blocking condition hanging both
runspaces. As a result, I am unable to update the form based on an event being fired by a control.
In the example below, the form is loaded and the following steps occur:
1.) Update-Combobox is called and it populates the combobox with a list of service names and selects the first item.
2.) update-textbox is called and sets the Text property of the textbox.
3.) The Text value of the textbox is read by the function read-textbox and output using write-host.
4.) An event handle is registered for the SelectionChanged event for the combobox to call the update-textbox function used earlier.
5.) If you change the selection on the combobox, the shell and UI hangs as soon as $SyncHash is referenced. I suspect this is causing some sort of blocking condition from multiple threads trying to access the synchronized nature of the hash table, but I am
unsure as to why / how to work around it. If you comment out the line "$SyncHash.TXT_Output.Dispatcher.Invoke("Send",[action]{$SyncHash.TXT_Output.Text = $Value})" within update-textbox the event handler will execute/complete.

Thanks again for the responses. This may not be possible, but I thought I would throw it out there. I appreciate your help in looking into this.
To clarify the "Respond to control events in the main runspace"... I'm would like to have an event generated by a form object in the UI runspace (ex: combo box selectionchanged event) trigger a delegate within the main runspace and have that delegate in
the main runspace update the form in the UI runspace.
ex:
1.) User changes selection on combo box generating form event
2.) Event calls delegate (which I have gotten to work)
3.) Delegate does some basic processing (works)
4.) Delegate attempts to update form in UI runspace (hangs)
As to the delegates / which runspace they are running in. I see the $synchash variable if I run get-var within a delegate, but I do not see the $Form variable so I am assuming that they are in the main runspace. Do you agree with that assumption?

Using two cursors, one for updating salary values in the emp table

Using COPIES of the employee and department tables provided by Oracle or using similar taples that provide employee, salary, job and dept in one table and dept number and department name in another table, write the following program. Use the dept table to step through sequentially and bring up the records with the same department from the employee table. Using an IF statement calcuate a new salary based on the job (you decide on the criteria). Update each record on the employee file (this is why you should use copies) with the new salary. In addition, calculate the total salary for each department and create a new table with the department number, the department name and the salary.
I'm able to update the salary values, but I'm not sure how to insert those updated values into an empty table the way this problem is asking me to.
Here's my script so far: any help would be greatly appreciated: )
declare
v_deptno emp.deptno%type;
v_job emp.job%type;
v_sal emp.sal%type;
v_dname dept.dname%type;
v_deptsal totalsal.deptsal%type;
cursor salup_c is
select job,sal
from emp,dept
where emp.deptno = dept.deptno
for update of sal;
cursor totdeptsal_c is
select dname,sal
from emp,dept
where emp.deptno = dept.deptno;
Begin
open salup_c;
loop
fetch salup_c into v_job,v_sal;
exit when salup_c%notfound;
if v_job = 'CLERK' then
v_sal := v_sal + 10;
else
if v_job = 'ANALYST' then
v_sal := v_sal + 20;
else
if v_job = 'MANAGER' then
v_sal := v_sal + 30;
else
if v_job = 'PRESIDENT' then
v_sal := v_sal + 40;
else v_sal := v_sal + 50;
end if;
end if;
end if;
end if;
update emp
set sal = v_sal
where current of salup_c;
open totdeptsal_c;
v_deptsal := 0;
loop
fetch totdeptsal_c into v_dname, v_deptsal;
exit when totdeptsal_c%notfound;
v_deptsal := v_deptsal + v_sal;
insert into totalsal
values(v_deptno,v_dname,v_deptsal);
end loop;
close totdeptsal_c;
end loop;
close salup_c;
end;
/

The script is actually inserting some values into the new table but look at what I'm getting
Here it is: i only want the dept number ,the dept name, and total salary for each department.

How to add field value to the standard table

Hi,
How to add field value to the standard table?
for example:
when we go to TCODE SE16-> VBAK table -> on the selection screen if we press F4 against VBTYP we get all the available values for that field. How to add a new document Category value to this field so that it shows up in F4 help for that field.

Hi Asif,
I don't think it is possible and feasible for adding new field value to the field VBTYP because it is not possible through SPRO.
If u see the domain of this field VBTYP we have fixed values provided by SAP. There is no value table for this. If u have value table then it will be updated through SPRO. But still if u really want to add some value u can do that by getting access key and add the value in the fixed values of the domain. But of no use other than simply displaying in F4. Because for what ever value u created here there will be no documents in VBAK or any table using this domain.
Hope this is clear for u.
Thanks,
Vinod.

Hi,
You have to pass 'EKKO' and 'EKPO' i.e in caps to the exporting parameter I_STRUCTURE_NAME of the function module

I think this would work, if not pls let me know.

Help on fetching values form the Database Tables

Hi,
I am working on fetching the values from the Oracle base tables.
First the order will be submitted by the customer. Depending on the city name he mentioned I need to route the order details to two different queues.
For example if I(customer) insert a list of values(order details) to a table name "X" with the with city name as "San Jose" I need to fetch the values from this table "X" and route them to a Queue"A".
And again if I insert a list of values to a table name "X" with the with city name as "Milpitas" I need to fetch the values from the table "X" and route them to a Queue"B".
How do I do this in ESB. I know how to use Database adapter and MQ adapter to create connections between Table and queue.
Can any one help me on this.
Thanks
Ramana.

Hi Ramana,
Your use case may be implemented using Oracle ESB like this:
- Specify a database adapter for reading from DB, your table X. Select an appropriate polling strategy for this. When you finish the wizard, you should have a DB service and get a Routing Service (RS) "for free". The DB service should already be wired to the RS.
- Specify queuing services add appropriate routing rules with filters (that are based on the message content) and message transformations in your RS in order to route data to the queue of your choice.

How we can check Item UNIQUE value at the time enter the value

hi,
check unique item value.When entering value.
using record group.
How?
which trigger we can use?
Thanks & Records
venkat

Hi!
Do you want to check if a value already in your table?
if so, use the when-validate-item trigger like this:
begin
if
:your_block.your_item is null
then
return; --> nothing to check, exit trigger
end if;
for l_rec in ( select 1
                  from your_table t
                  where t.your_column = :your_block.your_item
                  and ( :your_block.rowid is null OR rowid != :your_block.rowid ) --> if it is not a queried record
                  and rownum = 1 ) loop
message ( 'The value ' || :your_block.your_item || ' is already in existence. Please enter another value or use our nice list-of-values.' );
message ( ' ' ); --> shows an alert not only a message in the status line
raise form_trigger_failure;
end loop;
end;Regards

When i am retreiving the values from the access table i am getting null val

Calculating a count of rows where value matches another column value in the same table

Hi,
I'm struggling to do something in DAX that seems to me should be super easy (coming from a SQL world)!
That is to count all rows in column 1 where the value matches the current value for column 1?
E.g something like this:
[Col2]=Count of rows in [Col1] where value = this.[Col1]
Where the results are as in the table below:
Col1, Col2
A, 2
A, 2
B, 1
Anyone?

Can I Use The RTE_ROWKEY or RTE_ROW_ID values in the WB_RT_ERRORS Table?

Can I use these values in any way to identify the specific row in the table that is generating the error? If not, is there another way to link the row in the WB_RT_ERRORS table to the specific row in the table that generated the error?

Could you be more clear?

Displaying a total sum value in the af:table - footer

Hello everyone,
I have seen various threads on how to calculate a summary column based on a af:column in an af:table. I would like the value of this column to be displayed in the af:table -> footer (right undernead the af:column)
I'm having trouble putting together the pieces. This is the last requirement I have on this page, so hopefully I won't have to start all over.
Here this what I have:
I have created my page. (jspx) I did not create the page with a "backing bean". I have seen in various threads that the backing bean can be used to programmatically populate the table.
This is what I have done so far.
For the DataModel:
I have created my entity object, and I have a view assigned to the object. I assigned the view to my Application Module.
For the UserInterface:
On the layout, I dragged the instance of the view from the page definition. I created an af:table.
My questions/train of thought are:
I didn't create a "backing bean" when I first created my jspx page. From the various threads that I have seen, they all reference this. Can anyone explain how I can do this when the page has already been created? I'm using jdev version 10.1.3.3
Within the backing bean, I assume this is where I would then create a method that would do the "sum" of my column.
To display the column:
I would then create an af:output_text and drag it to theh table footer. The binding section
If anyone has a prior thread that I haven't found that can point me in the right direction with what I already I would really appreciate it.
Thanks

Kuba,
By creating a managed bean against the page definition, you are able to access the "iterator". The iterator is an object that is based off of hte View object (which the page is build off of)... From there, you can then loop through the rows and add them together to come up with the total sum.
You can then reference this method in the TEST.java class since it was created as a managed bean.
I believe I got the gist of it now... Coming from an Oracle Forms perspecitive, it is actually pretty similar. Now I understand what Managed Beans are used for. Thanks again for the great example.

Render a column based on other column value in the same table

JDev 11.1.1.6.0
This may be a silly question but I am stuck
I need to conditionally render a column say A. Condition is like if the value in the other column B of same table is equal to F. I should render column A only when this condition is satisfied. I have tried the following code:
<af:column sortProperty="PhoneNumber1"
sortable="false"
headerText="#{bindings.A.hints.PhoneNumber1.label}"
id="c146"
rendered="#{row.PhoneNumber1ResponseFlag eq 'F'}">
<af:outputText value="#{row.PhoneNumber1}"
id="ot130"/>
</af:column>
<af:column sortProperty="PhoneNumber1ResponseFlag"
sortable="false"
headerText="#{bindings.B.hints.PhoneNumber1ResponseFlag.label}"
id="c80" rendered="true">
<af:outputText value="#{row.PhoneNumber1ResponseFlag}"
id="ot129"/>
</af:column>
The data shown in the table for column PhoneNumber1ResponseFlag is F. Still my condition is not working.

Timo was saying that it is not possible to render the column in some situations and not in anothers, you will always have to render the column.
The best way to do this is instead of showing a column with the text ' ', show something meaningfull to the user. This is a DataWarehouse advice to you and may be usefull since you're using ADF in a area that uses DataWarehouse..
So the code could be something like this (based on Timo's code):
<af:column sortProperty="PhoneNumber1"
sortable="false"
headerText="#{bindings.A.hints.PhoneNumber1.label}"
id="c146">
<af:outputText value="#{row.PhoneNumber1ResponseFlag eq 'False.' ? row.PhoneNumber1 : 'No value applied.'"
id="ot130"/>
</af:column>
<af:column sortProperty="PhoneNumber1ResponseFlag"
sortable="false"
headerText="#{bindings.B.hints.PhoneNumber1ResponseFlag.label}"
id="c80">
<af:outputText value="#{row.PhoneNumber1ResponseFlag}"
id="ot129"/>
</af:column>
Hope that helps,
Frederico.

hi,
1 there is one property OnAction of the button...
2 So, in this event handler,you have to read the context node to which ur table is binded
3 use the code wizard
control+f7
, and use the method
get_static_attribute_table
4 now u have got the vaues in internal table,so now as pointed in the previous reply, you can use the
Update
or
Modify
statement...

Amit

Poplist and displaying corresponding values from the database table

Hi
I have a poplist in a control block, the values of which are populated using a procedure. This is called in when-new-form-instance.
This part works fine and values are filled in the poplist when form is opened..
The datablock is based on a view. 3 columns from the view are selected to be displayed.
Also the databock is filled with all values (for selected columns)
Now when the poplist value is changed, I need the values in the datablock to be changed as well, but this is not happening.
In my when-list-changed trigger, I have:
go_block('datablock');
execute_query;Please tell , where and what should I add to display the datablock values as per the poplist value.
i.e, something like,
select col1,col2,col3 from <view> where col4 =:control.col4
Note:I tried in the where clause property of the block, but then nothing is displayed in the datablock
Thanks

This does not work , either..
Before, when I changed the values from the list, it was still displaying same data on datablock always(all records)
Now when I give this code,data is displayed in datablock only once(first time when the form opens)
I have defined the Query data source type property on data block as "Table" but infact this datablock is based on a view..is this correct?
Anything else I could try?

Filtering unique values in dataset

Hi, I have nice little dataset here, populated from xml. It
contains articles, categories.....
What I need is to initialize my custom menu class with unique
values from categories column. So how do I query my dataset to
return me only unique categories?
I could do it in my xml parser (extract uniques in array),
but that would be poor design.
So please help! Need those uniques out of dataset fast!

Could you please tell me how i will Filter duplicate
valus inside the objectI'm sorry, but I can't read the future.
