How to delete a row from table control

I have created a push button on the screen for delete.
its getting stored in ok_code.
'FLAG' is the name of the mark on the table control.
I am getting probs in this line.
I am not getting anything in mark_field.
ASSIGN COMPONENT p_mark_name OF STRUCTURE <wa> TO <mark_field>.

Hi...
i got the same prob...but got the solution too...
you have to take an internal table of same type of dbase table..and maintain a flag in it...which will be get filled automatically with 'X'.
here is the code..go throug it..

Delete multiple rows from table/list control

Hi,
I want to have a table control in which a user can enter different entries, like this:
My program would read each entry at a time and do something.
However, I would like to give the user ability to delete multiple entries at once, like in an Excel spreadsheet - that is, the user selects multiple rows and presses "Delete" key and those entries get deleted. The Labview table does not allow this it seems - I can only delete one entry at a time - or I have to right-click and select Data Operations->Cut Data, which is awkward.
Is there a control better suited to what I want to do? I tried a Llist control, but it behaves in the same manner.
Thanks in advance!
Solved!
Go to Solution.

You could write your own routine. Use an Event Structure with a Key Down event. If the delete key was pressed and the table has focus delete the elements that are selected.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

How to delete certain rows from Table view

Hi Experts,
I need to display result on the basis of certain process type. So i have used code like below.
       lv_iterator =   me->typed_context->searchresult->collection_wrapper->get_iterator( ).
       lv_entity = lv_iterator->get_first( ).
       WHILE lv_entity IS BOUND.
         CLEAR:lv_object.
         lv_object = lv_entity->get_property_as_string( iv_attr_name = 'PROCESS_TYPE' ).
         IF lv_object <> 'XXX'.
           lr_entity ?= lv_entity.
          me->typed_context->searchresult->collection_wrapper->remove( lv_entity ).
          lr_entity->delete( ).
         ENDIF.
         lv_entity = lv_iterator->get_next( ).
       ENDWHILE.
But only some of the entities from the collection are getting removed. Still some wrong entities exists which i cant even able to delete it by using ,
          me->typed_context->searchresult->collection_wrapper->remove( lv_entity ).
          lr_entity->delete( ).
Am i missing anything here?

Hi Santhosh,
Maybe that is happening because you're removing elements from an object (collection_wrapper) inside your loop.
Can you try to create an collection wrapper copy by using GET_COPY method, and then use and loop the iterator on your copied object, and remove the unwanted entities on your main object?
Kind regards,

Deleting a row from a table using jsp

Given a table in a jsp, can an user click on a row of that table and retrieve the information so that the program can delete a record from a database table?
most of the tables that I have seen are static, the user cannot interact with them(specially when the user wants to delete several records from a database table).
Can anyone suggests a good book or way of deleting a row from table using jsp.

eg use a column in the table that has a radio button or check box,
on submit, get all the rows that are checked, using the row as an index into your db store, get the key and use the key to issue the sql delete command.

Deleting rows from table based on value from other table

Hello Members,
I am struck to solve the issue said below using query. Would appreciate any suggestions...
I have two tables having same structures. I want to delete the rows from TableA ( master table ) with the values from TableB ( subset of TableA). The idea is to remove the duplicate values from tableA. The data to be removed are present in TableB. Catch here is TableB holds one row less than TableA, for example
Table A
Name Value
Test 1
Test 1
Test 1
Hello 2
Good 3
TableB
Name Value
Test 1
Test 1
The goal here is to remove the two entries from TableB ('Test') from TableA, finally leaving TableA as
Table A
Name Value
Test 1
Hello 2
Good 3
I tried below queries
1. delete from TestA a where rowid = any (select rowid from TESTA b where b.Name = a.Name and a.Name in ( select Name from TestB ));
Any suggestions..
We need TableB. The problem I mentioned above is part of process. TableB contains the duplicate values which should be deleted from TableA. So that we know what all values we have deleted from TableA. On deleted TableA if I later insert the value from TableB I should be getting the original TableA...
Thanks in advance

drop table table_a;
drop table table_b;
create table table_b as
select 'Test' name, 1 value from dual union all
select 'Test' ,1 from dual;
create table table_a as

How to delete a row of table in Word using powershell.

I want to search for a word which is present in Table. If that word is present than I want to delete that row from table.
Can anybody help me with that. The script I am using is:
$objWord = New-Object -ComObject word.application
$objWord.Visible = $True
$objDoc = $objWord.Documents.Open("C:\temp\Recipe.docx")
$FindText = "DP1"
$objSelection.Find.Execute($FindText)
$objWord.Table.Cells.EntireRow.Delete()
$objDoc.SaveAs("C:\Temp\P.docx")
$Doc.Close()

Maybe try this:
$objWord = New-Object -ComObject word.application
$objWord.Visible = $True
$objWord.Documents.Open("C:\temp\Recipe.docx")
$FindText = "DP1"
$objWord.Selection.Find.Execute($FindText) | Out-Null
$objWord.Selection.SelectRow()
$objWord.Selection.Cells.Delete()
$objWord.Documents.SaveAs("C:\Temp\P.docx")
$objWord.Close()
$objWord.Quit()
[System.Runtime.InteropServices.Marshal]::ReleaseComObject([System.__ComObject]$objWord) | Out-Null
This definitely assumes the text you're trying to find only exists in a table, per your specified requirements. If it exists anywhere else, or in multiple tables, the code above is inadequate.
I hope this post has helped!

Delete operation is not working to delete selected row from ADF table

Hi All,
We are working on jdev 11.1.1.5.3. We have one ADF table as shown below. My requirement is to delete a selected row from table, but it is deleting the first row only.
<af:table value="#{bindings.EventCalendarVO.collectionModel}" var="row"
rows="#{bindings.EventCalendarVO.rangeSize}"
emptyText="#{bindings.EventCalendarVO.viewable ? applcoreBundle.TABLE_EMPTY_TEXT_NO_ROWS_YET : applcoreBundle.TABLE_EMPTY_TEXT_ACCESS_DENIED}"
fetchSize="#{bindings.EventCalendarVO.rangeSize}"
rowBandingInterval="0"
selectedRowKeys="#{bindings.EventCalendarVO.collectionModel.selectedRow}"
selectionListener="#{bindings.EventCalendarVO.collectionModel.makeCurrent}"
rowSelection="single" id="t2" partialTriggers="::ctb1 ::ctb3"
>
To perform delete operation i have one delete button.
<af:commandToolbarButton
text="Delete"
disabled="#{!bindings.Delete.enabled}"
id="ctb3" accessKey="d"
actionListener="#{AddNewEventBean. *deleteCurrentRow* }"/>
As normal delete operation is not working i am using programatic approach from bean method. This approach works with jdev 11.1.1.5.0 but fails on ver 11.1.1.5.3
public void deleteCurrentRow (ActionEvent actionEvent) *{* DCBindingContainer bindings =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding dcItteratorBindings =
bindings.findIteratorBinding("EventCalendarVOIterator");
// Get an object representing the table and what may be selected within it
ViewObject eventCalVO = dcItteratorBindings.getViewObject();
// Remove selected row
eventCalVO.removeCurrentRow();
it is removing first row from table still. Main problem is not giving the selected row as current row. Any one point out where is the mistake?
We have tried the below code as well in deleteCurrentRow() method
RowKeySet rowKeySet = (RowKeySet)this.getT1().getSelectedRowKeys();
CollectionModel cm = (CollectionModel)this.getT1().ggetValue();
for (Object facesTreeRowKey : rowKeySet) {
cm.setRowKey(facesTreeRowKey);
JUCtrlHierNodeBinding rowData = (JUCtrlHierNodeBinding)cm.getRowData();
rowData.getRow().remove();
The same behavior still.
Thanks in advance.

JDev 11.1.1.5.3 sounds like you are using oracle apps as this not a normal jdev version.
as it works in 11.1.1.5.0 you probably hit a bug which you should file with support.oracle.com...
Somehow you get the first row instead of the current row (i guess). You should debug your code and make sure you get the current selected row in your bean code and not the first row.
This might be a problem with the bean scope too. Do you have the button (or table) inside a region? Wich scope does the bean have?
Anyway you can try to remove the iterator row you get
public void deleteCurrentRow (ActionEvent actionEvent) { DCBindingContainer bindings =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding dcItteratorBindings =
bindings.findIteratorBinding("EventCalendarVOIterator");
dcItteratorBindings.removeCurrentRow();Timo

How to delete multiple rows from ADF table

How to delete multiple rows from ADF table

Hi,
best practices when deleting multiple rows is to do this on the business service, not the view layer for performance reasons. When you selected the rows to delete and press submit, then in a managed bean you access thetable instance (put a reference to a managed bean from the table "binding" property") and call getSeletedRowKeys. In JDeveloper 11g, ADF Faces returns the RowKeySet as a Set of List, where each list conatins the server side row key (e.g. oracle.jbo.Key) if you use ADF BC. Then you create a List (ArrayList) with this keys in it and call a method exposed on the business service (through a method activity in ADF) and pass the list as an argument. On the server side you then access the View Object that holds the data and find the row to delte by the keys in the list
Example 134 here: http://blogs.oracle.com/smuenchadf/examples/#134 provides you with the code

Deleting the Row from the table is not refreshing the contents in the form

Hi,
We developed a table and form in the same UI based on the following suggestion.
Display and edit currently selected row of ADF Table in ADF Form
1. Created one view object based on the employees table.
2. dragged the view object to the UI as table.
3. dragged the view object as form.
4. set partial triggers on the form's container (panelformlayout) as tableId.
Tested the application with the edit options and everything is working fine. But the problem comes when we delete the record from table. it is not refreshing the form based on the newly selected row after deleting the record. If we commit the data the form contents are updated to the selected row (which is not desired).
Can you please suggest how to fix the issue, refreshing the form with the selected row after deleting the records.
Thanks and Regards,
S R Prasad

The Code snippet looks fine. I think, the issue is in the partial trigger setting
4. set partial triggers on the form's container (panelformlayout) as tableId.In order to the table to get refreshed, the table's partialTriggers property should be set to id of the delete Button.
Go to table, select partialTriggers in the Property Inspector, Click on Expression Builder at the right and select the delete Button.
Can you set this and check?
Sample Code:
<af:panelHeader text="panelHeader 1" id="ph1">
<f:facet name="context"/>
<f:facet name="menuBar"/>
<f:facet name="toolbar">
<af:commandButton text="Delete" id="cb1"/>
</f:facet>
<f:facet name="legend"/>
<f:facet name="info">
<af:table var="row" rowBandingInterval="0" id="t1"
partialTriggers="::cb1">
<af:column sortable="false" headerText="col1" id="c1">
<af:outputText value="#{row.col1}" id="ot1"/>
</af:column>
<af:column sortable="false" headerText="col2" id="c4">

<af:column sortable="false" headerText="col5" id="c2">

Deleting a row from a table control through right-click menu

I have a table control. I want to delete a row from it when a user right clicks on a particular row and selects "Delete row" menu item. I have managed the creation of menu item but have not been able to delete the row which is right clicked and the menu item "Delete row" is selected. Guidance required! Thanks!

It's irrelevant whether the table is a control or indicator. See attached VI.
Hi smercurio,
please see the attached picture. In my previous post i mean the different in the menu. The red marked function is not available, if the table is an indicator. LV8.5!

Deleting a row from parent table

Dear Guru's
I am having two table with parent - child relationship. My problem is when I am deleting a row from parent table the curresponding child row from child table also should be deleted.
My Primary table 'Employee, EMPID Primary key
Child table 'Privilage' inthis EMPID referencing the EMPID of Employee table
My need is when I am deleting a row from parent table the curresponding child row from child table also should be deleted
I issued the SQL query like,
delete from employee where empid='12345' cascade constraints;
Then it showing me error like,
ERROR at line 1:
ORA-00933: SQL command not properly ended
Please resolve my issue , Its Top urgent
Thanks & Cheers

Choosing How Foreign Keys Enforce Referential Integrity
Oracle Database allows different types of referential integrity actions to be enforced, as specified with the definition of a FOREIGN KEY constraint:
Prevent Delete or Update of Parent Key The default setting prevents the deletion or update of a parent key if there is a row in the child table that references the key. For example:
CREATE TABLE Emp_tab (
FOREIGN KEY (Deptno) REFERENCES Dept_tab);Delete Child Rows When Parent Key Deleted The ON DELETE CASCADE action allows parent key data that is referenced from the child table to be deleted, but not updated. When data in the parent key is deleted, all rows in the child table that depend on the deleted parent key values are also deleted. To specify this referential action, include the ON DELETE CASCADE option in the definition of the FOREIGN KEY constraint. For example:
CREATE TABLE Emp_tab (
    FOREIGN KEY (Deptno) REFERENCES Dept_tab
        ON DELETE CASCADE); Set Foreign Keys to Null When Parent Key Deleted The ON DELETE SET NULL action allows data that references the parent key to be deleted, but not updated. When referenced data in the parent key is deleted, all rows in the child table that depend on those parent key values have their foreign keys set to null. To specify this referential action, include the ON DELETE SET NULL option in the definition of the FOREIGN KEY constraint. For example:
CREATE TABLE Emp_tab (
    FOREIGN KEY (Deptno) REFERENCES Dept_tab
        ON DELETE SET NULL);

Deleting a row from a table containing CLOB as one of the columns

When i delete a row from a table which contains a CLOB (internal clob) i.e. CLOB or BLOB column, Will the CLOB data will also be deleted ? I understand that what exactly stored in the CLOB column is the clob locator which points to the actual data.
So, when I delete this row, the clob locator will be deleted, but will the actual data what this locator is pointing to is also deleted ??? if not what is the process to delete the data the locator is pointing to when the row containing the locator is deleted ? If this is not happening then the actual data might become an orphan data which nobody has access to, will automatic garbage cleaning occurs on a frequent intravels to delete unaddressed data residing on the database server ?
Thanks in advance for the help, can email me at [email protected] alternatively.
Regards,
Srinivasa C.

Michael,
Thanks very much for your inputs, here are the results i got when i tried the way you explained in your answer, the TRUNCATE command made the actual size back to normal, but the delete is not the same, so, how can i delete the data that a particular clob locator may point to ?
truncate would delete all the rows of the table, which might not serve my purpose, i would like to delete a row and also it's associated clob data from the database! is there anyway to do this ?
is there any limitation on the ool_sample size? i am basically a c++ programmer, i am looking for some function like FREE which would free the allocated memory to the clob once the locator is deleted.
your help is greatly appreciated - Thanks!
:-) Srini.
