Remove all rows from a JTable.

I carnt seem to work out how to do it, surely there is a way.
Thank you

for those people who search for a thread like this and find it i solved it by doing this.
DefaultTableModel d =(DefaultTableModel)<Your Table Name>.getModel();
int rowCount = d.getRowCount();
for(int i=0; i < rowCount; i++){
d.removeRow(0);
The reason for the "0" in remove row is because it will automatically resize the rows down one and effectively you want to remove all the rows until there isnt any in the last row. :)

How to remove a row from a jtable with DefaultTableModel

Hi to all,]
I want to remove a row from jtable. I am using DefaultTableModel.
I have got some example but every example is given with AbstractTableModel
Please help me...
Thanks and Regards

I want to remove a row from jtable. I am using DefaultTableModel.How do you program without reading the API.
The name of the method you use is "removeRow". How hard is that to find by reading the API?
Not only do you not bother to read the API, you don't even bother to read and respond to your old postings when you get help:

Removing rows from a JTable

How can i remove a row from a JTable??

You need to extends AbstractTableModel rather than use DefaultTableModel as I think from memory this just uses an array to store data.
If you use a vector in your subclass to store your rows, then you can do something like this:
    public boolean delete(int rowIndex)
        if (rowIndex < 0 || rowIndex >= rowVector.size())
            return false;
        else
            int day = 0;
            MyRowClass row = rowVector.get(rowIndex);
            rowVector.remove(rowIndex);
            rowCount--;
            fireTableRowsDeleted(rowIndex, rowIndex);
            return true;
    }HTH

Deleting a row from a JTable using a custom TableModel

Before I waste any of your time I would like to go ahead and just say that I have searched through the forum using "delete row from Jtable" as the search keywords and while I have found very closely related issues, they have not solved my problem. I have found code postings by carmickr and his arguments as to why we should use DefaultTableModel instead of having created our own custom TableModel, and while I do agree, I just am not quite confident enough in applying it to my scenario. See I am reading from a file a bunch of Contractor objects and I am stuffing it into an arraylist which I am using in the following code posting to populate my TableModel which the JTable object in the gui then uses.
My problem is that everything works except when I delete and when I delete I understand that the index is changing because I just removed a row from the arraylist object. Suppose I have 33 rows displaying in the GUI. Now after I delete say row #23, the delete function works and dutifuly the row disappears from the table, but if I try to delete a row say...the last row, it does not work and throws me an IndexOutOfBoundsException which totally makes sense. My question is how do I go about fixing it? Do I have to do something with the setRowCount method?
Any help is appreciated.
Cheers,
Surya

Wow that was a very quick response. Thanks camickr. I am only trying to delete a single row. I do not know how to go about posting a test program for the code I have posted above because honestly the gui itself is 800 lines of code, and then the file reading class is quite funky in itself. I can maybe email you the entire Netbeans project including code so if you are using Netbeans 5 RC2 you can run the code and see for yourself, but that would not be considerate of me.
See I am trying to delete any row at any time...but only one at a time not multiple rows...so if a user decides to delete row 23 and then tries to delete the last row which happens to be row 33 in my case, my setup should be smart enough to still allow to delete the row.

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?

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

Remove a row from multiple tables

Hello,
I have a form that has what appears to be one table. Since I needed 30 columns (29 of them are single character fields) I had to use 2 table objects. Then I needed the ability to add and remove rows. Adding a row at the end is easy enough. Deleting a specific row is the problem. At the moment, I added a third table which has a header row and a item body row. the body row is a button with the intention of removing that entire row from the large table. This means it needs to remove the row from all 3 tables.
My structure is:
form1
(Some other flowed subform that doesn't matter for us)
SubformPersonnel (a flowed subform)
SubformHeader (a positioned subform)
TextOverallHeader (text to label the oeverall 3 tables)
ButtonAddRow (adds a row to the end of all 3 tables)
SubformPersonnelTable (a positioned subform)
ContractorTableRemove (a table with 1 column for the Remove button)
HeaderRow (A hidden row to align the table with the other 2)
Item (A row with the Remove button)CellRemoveButton (the cell with the remove button and associated JavaScript)
ContractorTableLeft (a table with the left 15 printed columns)
HeaderRow
Contractor (A row of data to be removed when CellButton above is clicked)
ContractorTableRight (a table with the right 15 printed columns)
HeaderRow
Contractor (A row of data to be removed when CellButton above is clicked)
(Some other flowed subforms that I am not worried about at the moment)
The 3 tables are aligned so the headers all line up, with no spaces between them. The body rows then line up and this looks like one large table. From left to right, they are:
ContractorTableRemove, ContractorTableLeft, ContractorTableRight
So Item and Contractor rows are added when ButtonAddRow is clicked in the overall header. The intial count is set to 8 for each table, so I get 8 rows at startup. The minimum count is set to 1 for each. I know that each row of each table has the same index number because I filled those into a cell in each table durig the cell's initialize. This line, in the CellRemoveButton's click event deletes that cell's row in that table:
this.parent.parent._Item.removeInstance(this.parent.index);
I have tried all sorts of ways to delete the same row (using same index #) in the other 2 tables: ContractorTableLeft and ContractorTableRight, but don't seem to be getting the correct syntax correct. I have tried hard coding the references, using .parent as shown below, and also tried using an index of 1 just to try deleting a row with no results.
     this.parent.parent.parent.ContractorTableLeft._Contractor.removeInstance(this.parent.inde x);
Can someone get me the correct syntax here?
I have seen examples of putting a hidden delete button on each table and clicking that, but I am concerned that it will get in the way of the tables on either side of the table it is in. I reeally want to just reference the row and remove it so I can avoid any problems these additional delete problems may cause.
I have copied the form to https://acrobat.com/#d=7M8R50rEHf4AaVXppwyKLw

Thank you, Niall. Much appreciated!
The Delete button was more to make sure one could delete these outside a button in the actual row and I see I had the index wrong such that I was deleting the second row and not the first. I had toyed with using this as a hidden button if I could pass the index to the event's function.
I had not thought of adding the reference to each row as a variable. It seems to work very well.
For future reference to others, here is the code from the cellRemoveButton click event:
     // Declare some variables
     var i = this.parent.index;
     var oContractorLeft = ContractorTableLeft.Contractor;
     var oContractorRight = ContractorTableRight.Contractor;
     // Remove this row by accessing its index within the set of 'Item' row instances of the parent table
     _Item.removeInstance(i);
      // Since this table is actually 3 tables, we need to remove the other two table's instances as well.
     // Their index should be the same, so we just need to get their names correct.
     oContractorLeft.instanceManager.removeInstance(i);
     oContractorRight.instanceManager.removeInstance(i);
      // removing the row doesn't trigger calculations in tables in the form's current target (fixed in later versions of Acrobat)
     // force calculations to fire so the ItemIndex field's value is updated according to the remaining row's indexes
     // see http://forms.stefcameron.com/2006/05/20/add-recalculate/
     xfa.form.recalculate(1);
Again, thank you!

Removing duplicate rows from SELECT

Hi, I was wondering if there was any way to remove duplicate rows from a select statement.
My table looks like this:
CREATE TABLE CUS_ID_TO_PC_ID (
CUSTOMER_ID VARCHAR2 (10) NOT NULL,
PC_ID VARCHAR2 (25) NOT NULL,
PASSWORD VARCHAR2 (25) NOT NULL,
REG_DATE DATE,
PRODUCT_DESC VARCHAR2 (25),
EXPIRE_DATE DATE,
SERIAL_NBR VARCHAR2 (12),
LDAP_USER VARCHAR2 (200),
COMMENTS VARCHAR2 (2000),
PC_ID_5_4 VARCHAR2 (25),
PC_ID_6_0 VARCHAR2 (25),
PASSWORD_5_4 VARCHAR2 (25),
PASSWORD_6_0 VARCHAR2 (25),
PC_ID_6_1 VARCHAR2 (25),
PASSWORD_6_1 VARCHAR2 (25),
OPERATING_SYSTEM VARCHAR2 (20),
STATUS VARCHAR2 (1)
Basically, I want to retrieve all columns from the table but remove all duplicate variations of
the pc_id/serial_nbr combinations.
For example, given this data:
PC_ID SERIAL_NBR CUSTOMER_NO
1234567 AAA C345
1234567 AAA C567
3333333 BBB C456
only the 1st and 3rd rows would be returned.
Any ideas?

Try something like this:
select * from your_table yt
where rowid in (select max(rowid)
from your_tabel yt2
where yt2.pc_id = yt.pc_id
and yt2.serial_nbr = yt.serial_nbr);

Selecting rows from a JTable using keys

Hi all, be very grateful for some help on this.
I want to provide functionality in an application where the user will be able to select multiple rows from a JTable by using the page up/ page down button.
Anybody know how this can be done?
Thanks

Just add a KeyListener to the table which does what you want on pressing the relevant key.
it seems a bit odd though. If I pressed page up/down in a table I'd expect it to scroll and would be somewhat confused if it started selecting stuff. Generally it's best not to muck around with the default behaviour of UI components.

Deleting rows from a JTable

Hello,
I've got a JTable which is based on a 2-dimensional array, which contains my data. Now I want to delete several rows from the JTable. There's the possibility to modify my data-array by creating a new array which doesn't contain anymore the datasets I want to delete. Afterwards I can redraw the table and my rows are deleted. But I think that's a very complicated way to delete rows from a JTable. Can anybody tell me whether ther's an easier way to do so ? I'd really be pleased...
Thanx,
Findus

When you create a TableModel using a two-dimensional array or a Vector of Vectors, a DefaultTableModel is created and it stores the data in its own Vector of Vectors. The DefaultTableModel supports methods for adding/removing rows of data. To remove the first row in the table you would do something like:
DefaultTableModel model = (DefaultTableModel)table.getModel();
model.removeRow( 0 );
Note: once you create the TableModel you should set your array to null as it is not used anymore.

Ipod 5 wasn't updating new playlists. Removed all music from iPod and ended up with 34 GB of OTHER. How do I remove this without doing a full restore?

iPod 5 was not adding new playlists when synching (plenty of space remained in memory for it). This happened around the time of the new update. I removed all music from the iPod and when I went to resync the selected playlists, my OTHER portion of memory jumped up to 34GB and now there is not enough space on the iPod to put all my music back on.
I've checked the usage of all the apps and photos, etc, it is pretty clear this is because of the music portion only.
Is there anyway of removing this information? Without doing a restore? It is not jailbroken either.

An "other" larger than about 1 1/2 GB indicates corrupted files.

How can I remove all photos from my iphone?

How can I remove all photos from my iphone?

Hi pjdemeo,
I understand you want to delete all of the photos from your iPhone. As a precaution, I would suggest importing the photos and videos from your iPhone into your computer. This will give you a backup for the images, and after import you will be asked if you want to delete the photos.
Import photos and videos from your iPhone, iPad, or iPod touch to your Mac or Windows PC - Apple Support
https://support.apple.com/en-us/HT201302
The iPhone User Guide has instructions for deleting photos directly from the device:
Organize photos and videos - iPhone
http://help.apple.com/iphone/8/#/iphf14943e
Delete a photo or video from Photos. Tap the Photos tab, tap the photo or video, tap , then tap Delete Photo or Delete Video. Deleted photos and videos are kept in the Recently Deleted album on iPhone, with a badge showing the remaining days until the item is permanently removed from iPhone. To delete the photo or video permanently before the days expire, tap the item, tap Delete, then tap Delete Photo or Delete Video. If you use iCloud Photo Library beta, deleted photos and videos are permanently removed from all iOS 8.1 devices that use iCloud Photo Library beta with the same Apple ID.
Cheers,
- Judy

How do I remove all apps from my iPhone?

How do I bulk remove all apps from my iPhone? There has to be a better way than removing each one manually. Thanks.

It's easiest to plug it into the computer if you have a lot, and click on the Music tab of the iPhone. Then, either Control-A (Windows) or Command-A (Mac) to select all of the songs then press delete on your keyboard. If you have a few, it is easiest to swipe over the individual songs and press delete.

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

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.
