Hello
I'm trying to remove the lines that contain a multiple of the x-data in the original table and have the output array display the original array less table of harmonics of delete.
Original array:
3 100
18 200
13 300
8 400
500 0
600 0
700 0
Deletes rows that contain multiples of 300. Output array will be
3 100
18 200
8 400
500 0
700 0
Any help will be really appreciated.
Thank you

Inserted row is the same as the deleted row
Hello
I have another weird behavior with ADF I don't understand... When I delete a line in an af:table and then I insert a line, the insert row is identical to the deleted row. Here is what I do
- Go to the page, the table is loaded with a record from the database
- Remove the line, using a button that triggers the delete of the iterator method in links
- Insert a new line using a method defined in the Application module implementation java class. He defines himself as a methodAction in links
- The insert in my interface button calls a method in my java bean
public void insertNewVariableScheduleRow(ActionEvent ae) { insertNewVariableScheduleRow((DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry()); } private Row insertNewVariableScheduleRow(DCBindingContainer bindings) { OperationBinding method = bindings.getOperationBinding("insertNewVariableScheduleRow"); Map paramsMap; Row newRow; paramsMap = method.getParamsMap(); paramsMap.put("defaultValues", scheduleDefaultValues.toArray()); method.execute(); logger.log("(method.getErrors().size(): " +(method.getErrors().size())); newRow = (Row)method.getResult(); return newRow; }
The method in the * class AMImpl do:
public Row insertNewVariableScheduleRow(int scheduleNo, int scheduleVersion, String declId, String[] defaultValues) { ViewObject vo = this.getDeclSchedCellUpdView(); int displOrder = getVariableScheduleNextDisplayOrder(); Row row = vo.createRow(); row.setAttribute("DisplOrder", displOrder); row.setAttribute("DeclId", declId +""); row.setAttribute("SchedVrsnNo", scheduleVersion +""); row.setAttribute("ScheduleNo", scheduleNo +""); for(int i=0; i<defaultValues.length; i++) { if(defaultValues[i] != null) { row.setAttribute("Col" +String.format("%03d", i+1) +"Value", defaultValues[i]); } } vo.insertRow(row); return row; }
I use JDev 11.1.1.7
Thank you for all your help
What is property changeEventPolicy on the iterator parameters in your pageDef? (try to define this 'None')
In addition, you can try to run the managed bean delete operation and then reset the State of the component with:
RicheTableau yourTable =...
yourTable.resetStampState ();
AdfFacesContext.getCurrentInstance () .addPartialTarget (yourTable);

deleted rows are raised when the form is reopened
I have a form that allows users to add and remove lines om a table. It works fine even if the user's display and the change of form, but when the form is saved and then re-opened, previously deleted rows return. How can I make sure that my deleted rows are deleted?
Remove the script to click to the button reads:
this.parent.instanceManager.removeInstance (this.parent.index);
Thank you for an overview of what is originally deleted rows reappear when the document is reopened.

This problem has been resolved by associating a schema to the form which enabled the form to save the State.

Add lines to and delete rows in a table to the issue of enforcement
I downloaded an example of Adobe for the addition or deletion of a line when running.
The example works fine, but it only allows to generate the maximum of 7 rows!
I tried to change the code but I missed. Can you help me?
Here's the code for the Add button
Form1. #subform [0]. Add::click - (JavaScript, client)
nTableLength stores the number of elements XML contained in table 1.var nTableLength = Table1.nodes.length;
var nNumRow = 0;
for (nCount var = 0; nCount < nTableLength; nCount ++) {}
If ((Table1.nodes.item (nCount) .className == "subform") & (Table1.nodes.item (nCount) .name! == 'HeaderRow')) {}
nNumRow = nNumRow + 1;
}
}If (nNumRow == 7) {}
xfa.host.messageBox ("the maximum number of lines is 7. You cannot add lines more. ","warning ", 3);
}
else {}
Table1.Row1.instanceManager.addInstance (1);

Select 3, Union 1 double all the
Select option 4, Union 2 double all the

I want to remove rows from attsht where corresponding booth (which is stored in the empbooth table) is 1.
The condition is 'where attsht.empid = empbooth.empid and empbooth.booth = 1 '.
I use oracle 10g.
Help, please
delete from attsht where a.empid in (select b.empid from empbooth b where b.booth = 1)

remove from attsht a

Hello!
I hope someone can please help me solve a problem, I'll have a table in my form. It offers a menu associated with each line that allows you to add, delete, reset, lines etc. The name of the table on the form is the array of points of purchase. This is the first table on the form.
Here are the steps to re-create the issue:
1. create 3 rows of the table
2. click on the menu ('X') associated with the first line button.
3. Select "remove this line. Nothing happens.
4. click on the menu ('X') associated with the first line button.
5. Select 'Remove this line' again. Nothing happens.
6. click on the menu ('X') associated with the first line button. You will notice that the "Remove this line" option is grayed out.
My best guess that the rows are deleted in the background, which is why if I have 3 rows and 'remove' 2, so my delete option is grayed out because according to me, it makes sense in there as if there is only 1 row then grey can delete lines. I was intending to join the file that I see others it, but do not see the option. I am pleased to provide you with the file by e-mail if that's easier. Thank you in advance!

I have posted the solution here:
http://www.fieldeffecttechnologies.com/AdobeForums/PCard.PDF
Instance Manager methods have been given the wrong index of the line to work with. They should be passed to the index of the row to which the button you press in (of course). Instead, they received a few index v8b, honestly, I can't decipher as to what this number means eventually. (Math.round ((v3-v4) * v6...)?)
Anyway, I have it repaired and also changed some of the logic in the submenu to determine what is gray.
I love this feature! It can even show a client!

Request to delete rows for table fa_mass_additions
Helloo
I need help to remove rows from the table fa_mass_additions Oracle EBS of assets fixed r12
Each line is characterized by a unique recnum. However, there are duplicate for the Serial_number entries. I need to remove all but 1.
For example
Recnum 60341 Serial_number 1110007600100
Recnum 60342 Serial_number 1110007600100
Recnum 60343 Serial_number 1110007600100
Recnum 60344 Serial_number 1110007600200

Recnum 60346 Serial_number 1110007600300
Recnum 60347 Serial_number 1110007600300
Note-see duplicates for serial numbers
After the removal of table should be
Recnum 60341 Serial_number 1110007600100
Recnum 60344 Serial_number 1110007600200
Recnum 60346 Serial_number 1110007600300
Any query sql or pl/sql will be greatly appreciated

A backup point might be something to consider, but that would be your business decision.
An alternative workaround that might be used would be to go ahead and after some lines in the meantime, but it is accepted that this should not be an obligation, and the system should operate in a consistent way.
Can I deduce that the number is not filled, that this value cannot reproduce? If these lines have a tag number, I think that you can check in the version of FATagNumberValidator.class (run a check of the Apps for assets and check for this version of the file). If the instance is not already have version 120.0.12010000.2, your site can be helped in this scenario, the application of Patch 18800958 - ADI WEB: NO DUPLICATE tag ERROR IN SPREADSHEET NUMBERS. There is more explanation of this issue of tag number in the Doc ID 1944256.1.
In raising this question if, you made me realize that we cannot have similar validation for the serial number, or at least we do not have a named validator in a similar way. I have to do further research on this aspect, but if this is the case, I think that the best I could do would be to log an improvement to that request it.

Hi experts,
I was practicing some backup and restore scenarios, and wonder how we can recover deleted from the rows (records) in the following situation:-
1.*without * archive log and without flashback database
2. with archive log mode and without flashback database.
3. No archive log and with flashback database activate (default for db_flashback_retention_target)
4 log archiving and flashback allows.
Assuming we use oracle 10.2 on windows server 2003... * and a database thing is OLTP system and cannot be taken down... * (looks very criticism)
This may seem like a silly question to all you experts, but it holds great significance for me... say I deleted 20 records (rows) of the table T1 and we have deleted records at 13:00 and came to know about 15:30...
I know this is a very basic scenario for most of you, but I would like to know the exact steps to follow...
any suggestions would be appreciated...
Thanks and greetings

Published by: vikrant dixit on April 2, 2009 21:58I need to add some line more in my last post.
If your autoextend on for this undo tablespace so undo tablespace management is AUTO then let oracle manage what is recommended, do not set undo_retention > 0 unless you use not flashback technology.
If you use flashback technology as flashback query, query version, transaction query, flashback table, then you must be precise to undo retention welcome this cancellation for a time specified as ideal starting point, your undo retention guranted
http://download.oracle.com/docs/cd/B19306_01/server.102/b14231/undo.htm#sthref1482
, another tech flashback as flashback database do not cancel but flashback connect you in FRA even with flashback drop table do not require cancel but a recyclebin his own disposition.
How retention should be your advisor to undo use database

Unwanted copies have file names with
