Remove repeated row in 2D array

Hi,
How can I remove the row for second repeated data in my 2D array regardless of the 2D array size.

Try this...
There are many variations possible.

How to remove a row from a rowset

HI,
I am trying to do a very simple thing, but I got stuck.
The problem:
I want to remove a row from a rowset, without removing the row itself. Especially I do not want to remove any entities.
I need this functionality in several situations, for example when I want to move a row from one rowset to another.
Another situation is when I have a viewlink not based on an association. When a row is modified so it does not fit to the viewlink's where clause anymore, I need a way to remove it manually (without removig any associated entities),
I hope someon can help me on this,
thanks,
Frank

Sascha:
The only workaround I can think of is a true hack, and you'd be entering into a unchartered territory. But, it may be worth a try.
First, you need to create a subclass of oracle.jbo.server.ViewObjectImpl in the oracle.jbo.server package. This is because you need to override one of the package private methods. Suppose you define oracle.jbo.server.TempBaseViewObjectImpl which extends ViewObjectImpl.
Override the following method:
int[] getDeleteParticipants()
This method returns an array of EO bases for which ViewRow's delete should cause deletion of EntityRow's.
So, before you remove a ViewRow, you should set some flag in your TempBaseViewObjectImpl, so that getDeleteParticipants() would return "new int[0];" This will cause no EntityRow's to be deleted. Only the ViewRow will be removed from the collection.
Note that you should reset this flag after the operation, so that you can delete the EntityRow's (when necessary).
Your real VO should then subclass TempBaseViewObjectImpl.
Once we fix this problem and provide a real API, you should remove TempBaseViewObjectImpl and extend your real VO from ViewObjectImpl instead of TempBaseViewObjectImpl.
Thanks.

First attempt to remove duplicate rows from a table...

I have seen many people asking for a way to remove duplicate rows from data. I made up a fairly simple script. It adds a column to the table with the cell selected in it, and adds the concatenation of the data to the left into that new column. then it reads that into a list, and walks through that list to find any that are listed twice. Any that are it marks for DELETE.
It then walks through to find each one marked for delete and removes them (you must go from bottom to top to do this, otherwise your row markings for delete don't match up to the original rows anymore). Last is to delete the column we added.
tell application "Numbers"
activate
tell document 1
-- DETERMINE THE CURRENT SHEET
set currentsheetindex to 0
repeat with i from 1 to the count of sheets
tell sheet i
set x to the count of (tables whose selection range is not missing value)
end tell
if x is not 0 then
set the currentsheetindex to i
exit repeat
end if
end repeat
if the currentsheetindex is 0 then error "No sheet has a selected table."
-- GET THE TABLE WITH CELLS
tell sheet currentsheetindex
set the current_table to the first table whose selection range is not missing value
end tell
end tell
log current_table
tell current_table
set list1 to {}
add column after column (count of columns)
set z to (count of columns)
repeat with j from 1 to (count of rows)
set m to ""
repeat with i from 1 to (z - 1)
set m to m & value of (cell i of row j)
end repeat
set value of cell z of row j to m
end repeat
set MyRange to value of every cell of column z
repeat with i from 1 to (count of items of MyRange)
set n to item i of MyRange
if n is in list1 then
set end of list1 to "Delete"
else
set end of list1 to n
end if
end repeat
repeat with i from (count of items of list1) to 1 by -1
set n to item i of list1
if n = "Delete" then remove row i
end repeat
remove column z
end tell
end tell
Let me know how it works for y'all, it worked good on my machine, but I know localization is causing errors sometimes when I post things.
Thanks,
Jason

Delete unwanted rows in 2D array when not knowing the index of which to delete

Hi!
I am kind of new to Labview and I hope that someone can help me with my problem.
First I import a spreadsheet from Excel into a 2-D array of string. For each row in the array I then want to compare the data in a specific column (which is a date (time stamp)) with today's date. Rows containing a date with lower number than today's date I want to put into a new array and the rest I have no need for.
I have succeeded in creating a time stamp for today's date so that it is consistent with the Excel time stamp. But for the comparing and creating a new array part I have no idea about how to do it. I have tried numerous ways with no luck at all (probably because I don't understand all of the VIs that I need to use).
Happy for all help that I can get!
Solved!
Go to Solution.

You're on the right track! (although your attempt will only list the datetime values)
What you'll need to add/change is the resulting array need to be connected to the loop as Shift register (with an initial empty array), and in the Case you'll either use Build array to add the current line or send the unmodified through.
You'll probably want to send the full array through and not only the datetime.
You'll probably need some tweak to only use date, but similar to this:

Remove Second Row From CSV

I've got a group of small CSV files - only about 15 and with about 30 rows each in. I'm running a script against them once a month so because they're so small and being processed infrequently they can read-in and treated as a string. I need to remove the
second row of the file though and I've got nowhere with it so far.
Sample data:
TimeIndex,CPU,FCP,NFS,CIFS,ISCSI,NetworkIn,NetworkOut,NetworkTotal,Filername
TimeIndex,CPU,FCP,NFS,CIFS,ISCSI,NetworkIn,NetworkOut,NetworkTotal,000-samplehostname
So the header is correct, but the sample hostname on the second row would be different for each file and that row shouldn't be there. The simplest thing to do is just wipe that row entirely.
Any ideas?
Thanks in advance
Adam

I have two ideas :-)
You mentioned that you are just reading in the files and treating them as strings. In this case, you'd want to split it to a collection of objects and remove the second row...like this:
$strMultiLineString = "Test
Test
Test"
$arrlines = {$strMultiLineString -split "`r"}.INvoke() #Force it into an object collection
$null = $arrlines.Remove($arrlines[1])
If you are importing the file as a csv, you could do something like this:
$csv = {Import-CSV -path "C:\Temp\Test.csv"}.Invoke()
$null = $csv.Remove($csv[1])
Here is more information on adding and removing items from arrays/collections:
http://www.jonathanmedd.net/2014/01/adding-and-removing-items-from-a-powershell-array.html
That should remove the line in question, but is only done in memory, sounds to me the OP wants it removed from the file, so you would need to save the changes back to the actual file

Repeated rows resulting from executeWithParams on query with bind variable

hi
Please consider this example application created using JDeveloper 11.1.1.3.0
at http://www.consideringred.com/files/oracle/2010/RepeatedRowsIssueApp-v0.01.zip
It has a View Object "EmployeesVO" based on a SQL query with a bind variable "EmailBVar".
The page "findEmployees.jspx" has executeWithParams dropped as an "ADF Parameter Form..." and the "EmployeesVOVI" collection as a table.
On "EmployeesVOVIIterator" the RangeSize has been modified from the default 25 to 10.
So, all straightforward stuff.
A scenario (sc1), running the page "findEmployees.jspx", specifying a value and clicking the "ExecuteWithParams" button results in repeated rows shown in the table, that is the first row (and subsequent rows) are repeated at row 11 (and subsequent rows),
as can be seen in the screencast at http://screencast.com/t/bn9QvV0qt
question:
- (q1) How can the repeated rows in scenario (sc1) be explained/avoided?
many thanks
Jan Vervecken

Thanks for your reply Nick Haralabidis.
it can be avoided by setting the EmployeesVO Access Mode to Range Paging and setting the Range Size to 10. Indeed, that does seem to avoid the repeating rows.
Now why you get this behavior when you don't specify Range Paging on the VO I don't know. It could be because: 1) it is a bug - the obvious answer ;) , 2) because setting the RangeSize on the EmployeesVOVIIterator without setting the Access Mode on the EmployeesVO to Range Paging is conflicting - but then again there is no warning or error produced by JDeveloper, 3) ...It does look like unintended behaviour, for a "default approach" like this.
In documentation section "39.1.5 Efficiently Scrolling Through Large Result Sets Using Range Paging " ...
at http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/bcadvvo.htm#ADFFD1179
... this Range Paging for a View Object seems to be described as an optimization, not as a requirement for functionally correct behaviour.
- about (q1)
Another approach that seems to avoid the repeated rows in scenario (sc1) is removing the value for the RangeSize attribute on the iterator, so the RangeSize is not specified.
Using the modified example application
at http://www.consideringred.com/files/oracle/2010/RepeatedRowsIssueApp-v0.02.zip
... this can be seen in scenario (sc2) in the screencast at http://screencast.com/t/0bpCo33i8J
Although, the documentation in section "22.4.2.2 Iterator RangeSize Attribute " ...
at http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/web_form.htm#ADFFD706
... does not seem to mention anything about not specifying the RangeSize attribute, it does say "... You can set it to -1 to have the full record set returned. ...".
As can be seen in scenario (sc2) the EL expression #{bindings.EmployeesVOVIIterator.rangeSize} resolves to -1 which suggests that not specifying the RangeSize attribute is the same as configuring the RangeSize attribute to -1.
questions:
- (q2) What is the preferred way to avoid having "the full record set returned", without having repeated rows as in scenario (sc1)?
- (q3) Is the default configuration of RangeSize="25" on the iterator intended behaviour (for an interator supporting an executeWithParams action)?
regards
Jan

Repeatable row disabled by default. Need to enable all rows based on value in XML.

I have a repeatable row in a table that is defaulted to read only.   If a certain value doesn't exist in the XML (populated != x), I want to make add / remove buttons visible and and make the text fields in the row and all subsequent instances Open.
when populated !=x:
This is the code:
if (xfa.host.name != "XFAPresentationAgent" && this.resolveNode("populated").rawValue != "x") {
oTargetField = this.resolveNode("#subform[2].tbl_people.person.name");
      oTargetField.access = "open";
oTargetField = this.resolveNode("#subform[2].tbl_people.person.relationship");
      oTargetField.access = "open";
oTargetField = this.resolveNode("#subform[2].tbl_people.person.age");
      oTargetField.access = "open";
When I use this, it only enables the first row and none of the subsequent rows/instances.
Any assistance would be greatly appreciated!
-Jeff

Hi DCS_JeffW,
I guess, you need to follow these steps:
1) You need to find the number of repeating rows first. Assuming that "people.person" is the repeating instance:
                var countOfPPInstances = xfa.resolveNode("....people.person").instanceManager.count;
2) Modify your code as follws:
                if (xfa.host.name != "XFAPresentationAgent" && this.resolveNode("populated").rawValue != "x")
                                for(var i=0;i<countOfPPInstances;i++)
                                 xfa.resolveNode(“..people.person[“+i+”].name").access=”open”;
                                                  xfa.resolveNode(“..people.person[“+i+”].relationship").access=”open”;
                                                  xfa.resolveNode(“..people.person[“+i+”].age").access=”open”;
Let me know if this works. Alternatively, you can mail me your form @ [email protected]

How to increase the number of rows in the array as needed

hello LV
I need advice following
1. To the sine signal of 100 data (100 sampling) to sort 250 rows in the array. It changes the sine signal in the plane that time.
2. To set up a new row by external trigger signal.
Thank you

Hi Nusorn,
Your question makes little to no sense. Could you explain further, perhaps send some example code of what you have done so far?

How do I remove a row from the database?

Guys and Gals,
I'm using Studio Edition Version 11.1.1.3.0.
The code below will delete a row from my table, but how do I actually delete the row from the database as well?
    DCBindingContainer dcbc = (DCBindingContainer)getBindings();
    DCIteratorBinding dcib = dcbc.findIteratorBinding("TipsSelectorIterator");
    dcib.removeCurrentRow();
    BindingContainer bindings = getBindings();
    OperationBinding operationBinding = bindings.getOperationBinding("Commit");
    Object result = operationBinding.execute();
    AdfFacesContext adffacesctx = AdfFacesContext.getCurrentInstance();
    adffacesctx.addPartialTarget(this.getQueryTable()); In this post, I believe Frank sums up what I should do: Remove row from af:table
>
The problem in your case is that this removes the row from the iterator but not your business service. EJB exposes explicit methods to remove an entity. A method lime removeEmployees(employee) >expsed on the EJB model must be called.
You can drag and drop the "removeEmployees" method then as a button to your page. Rename the text label to "Remove" or "Delete". In the opened dialog box, point the method argument to the >following EL #{bindings.iteratorName.currentRow.dataProvider}. Next time you press the button, the row is deleted from the iterator and the business service
Huh? So to delete the row, I need to expose a method. But where? Do I do this in the AppModuleImpl so I can expose it to the Client Interface? But then how do I access entities? And what data type is the #{bindings.iteratorName.currentRow.dataProvider}?
If anyone could point me in a general direction, it'd be great.

Frank and Shay,
Thank you both for your posts. I'm amazed there's such a great place to get help. Between the forums, ADF code corner, Not Yet Documented ADF Samples, various blogs and tutorials, it's obvious you guys really care about what you do.
On my example, that approach doesn't seem to work. I tried following it like so in one of the video tutorials by Shay: http://blogs.oracle.com/shay/2010/04/doing_two_declarative_operatio.html. Following Shay's approach, in my particular case, deletes only from the table. Perhaps it is due to my iterator / collection setup?
TipsSelector (1 to 1) -> TipsView (1 to *)-> DependentBom -(1 to * Recursive)> RecursiveBom
TipsSelector references the same View Object as TipsView, but it is set as a 1 to 1 relationship so that I can show TipsView on the page one record at a time. This is the same setup as Tuhra2's hierarchy veiwer example. TipsView / DependentBom is a classic parent / child setup. RecursiveBom is DependentBom referencing itself. Think of it as departments within departments within departments etc...
I have dragged TipsSelector's Named Criteria (All Queriable Attributes) onto my page and created an ADF Query with Table. A remove button on the table's toolbar calls the two actions, Delete (from TipsSelector's iterator) and then Commit. I have modified the code slightly from my previous post but the end result seems to be the same.
    BindingContainer bindings = getBindings();
    OperationBinding operationBinding = bindings.getOperationBinding("Delete");
    operationBinding.execute();
    bindings = getBindings();
    operationBinding = bindings.getOperationBinding("Commit");
    operationBinding.execute();
    AdfFacesContext adffacesctx = AdfFacesContext.getCurrentInstance();
    adffacesctx.addPartialTarget(this.getQueryTable());Page Def file
    <action id="Commit" InstanceName="AppModuleDataControl"
            DataControl="AppModuleDataControl" RequiresUpdateModel="true"
            Action="commitTransaction"/>
    <action IterBinding="TipsSelectorIterator" id="Delete"
            InstanceName="AppModuleDataControl.TipsSelector"
            DataControl="AppModuleDataControl" RequiresUpdateModel="false"
            Action="removeCurrentRow"/>On ppr of the query table, the row is gone. However, when I press the Search button on the query again, the record reappears.
This is beyond me. Am I somehow deleting from the query results but not the database?

How to remove a row from a rowset obtained via a CachedRowSetDataProvider

I have a table filled from a database that it is bound to.
I have the CachedRowSetDataProvider that supplies the rows.
I want to remove a row from the result set and can't figure out how.
There is a method ... removeRow(RowKey row).
and there is a method ... getRowKey(java.lang.String rowId)
How do I determine what the string id is for, say, row 3?
thanks
jim murray

Thats the tutorial I am working with.
My problem is that the statement tripDataProvider.refresh();
executed when the person drop down changes doesn't seem to clearing the previous persons results.
So I want to clear the rowset myself by deleting the rows individually.
I can find a method to delete a row if I supply the RowKey.
There is a method to get the rowkey if I know the RowID, which is a string.
Unfortunately I dont know the string to use for an arbitrary row.
There should be a simpler way to clear the data from a rowset.

Hierarchy: How to suppress duplicated/repeated rows in a BEx query

Hi Gurus.
I have a BEx query which displays data based on a Cost Element hierarchy. When the hierarchy is expanded to leaf level (or any level), all key figures and characteristics are displayed for the leaf level but are also repeated throughout all the levels above.
Is it possible to suppress the repeated rows in higher levels of the hierarchy and display a summary result only?
The issue we have is that if the user wishes to export or save a workbook, they will have to filter and manipulate the report a great deal which is impractical.
I'm hoping it's a simple setting that I've missed. I look forward to receiving the magic answer!! :o)
Thanks,
Angela

Hi All,
I've been playing around a bit more and found a setting which I hope my users will find acceptable:
From the query - Query properties -> Data Formatting tab - Multidimensional View -> select Display Rows hierarchically and expand to (chosen characteristic)
Can anyone tell me if I can set this as a default setting in the query designer, or will I need to create a view to save the setting?
Thanks all,
Angela

How to remove a row from JTable

Hi!
I'm used to remove rows from JTables getting the model and doing a removeRow(num) like this:
((DefaultTableModel)jTable1.getModel()).removeRow(0);
But with ADF and JDeveloper the model says it's a JUTableBinding.JUTableModel but its not accessible.

Or maybe is just better to refresh data in the jTable but I do not know either like doing it.

Problem removing certain rows in a JTable

My program displays a JTable consisting of several rows of data. I also have JButtons rendered into a column in the JTable to delete rows. Basically when a JButton is clicked, the respective row will be removed.
This works pretty well until I realised a logical problem.
Assume I have 3 rows of data - A,B and C.
When a row is removed, the remaining rows at the bottom will move up. If I remove row B, row C moves up. There are 2 rows remaining.
The problem is, when I click on the JButton for row C, it somehow tries to remove the third row which doesn't exists anymore. I can still remove row A though, because the JButton for row A corresponds for the top row. Row C remains 'stuck'. I suppose a row is removed like Vector elements do.
Is there a way to update the table or reconstruct the table after removal of rows?
I've tried
((DefaultTableModel)table.getModel()).removeRow(row);
((DefaultTableModel)table.getModel()).fireTableRowsDeleted(row, row);but it doesn't work.
I don't want to go into getDataVector(). I prefer to work directly on the TableModel.
Thanks in advance.

I don't understand your problem. If your "Delete" button is
rendered into a column in the JTablethen how can you have a delete button in a
row which doesn't exists anymore.?
To get better help sooner, post a [SSCCE (Short, Self Contained, Compilable and Executable, Example Program)|http://mindprod.com/jgloss/sscce.html] that demonstrates the incorrect behaviour.
