Delete 5million rows out of 70million rows ....
Hi All,
There are nearly 70 million rows in a table out of which 5 million rows needs to be deleted.
This table will be accessed by many users round the clock..
What is the better way to delete these with out causing any problem to users.
(I mean , with out holding locks for longer.. is there any way??)
Thanks,
Kishore

How to delete empty row without validation error in ADF Table(EMP)
Hi Everyone,
I am using EMP Table in ADF jspx page to insert the data into database.when i insert a row into table by createInsert operation,it inserting the row.But I need to delete that row immediately with out entering any value.
But it showing some validation error at empno.Is there any ways to delete the empty row?if not,what are the reasons that we can't delete the row.
could any one tell me the reasons!!
Thanks in advance!!
With Best Regards,
Amar
Edited by: 973755 on Dec 11, 2012 6:42 AMAmar,
I am little confused with your logic here.....
but if you are trying to remove the row by clicking Remove button, you can set the immediate property to true and that remove function will run without executing any entity validation.......

How to delete a row in Numbers on iPhone?
I'm pulling my hair out on this one. The "Help" for Numbers for iPhone both in-app and on the web states that to:
Delete a row anywhere in the table: Tap the bar left of the row, then tap Delete.
So here is what I see before I tap the bar left of the row:
There is no bar left of the row unless I first tap into one of the cells. Then, when I tap the bar left of the row, this is what I get:
I see no "Delete" on which to tap. Nor do I see "Hide" or "Insert", which, according the the Help, should also be available options once I've tapped that left side bar. The only things I am able to do with the row are move it up or down, and change its height.
Am I missing something, doing something wrong, or is this a bug in Numbers? I'm on an iPhone 5s with auto app updates, so I have the latest version of Numbers.
ThanksHi Varcar,
Usually when I tap the bar, as you did, I get a popup menu with some choices. Cut, Copy, Paste then an arrow taht I can then tap to reveal Delete, Hide, Chart. Have you tried to retap on the blue highlight on that bar? It might just want more attention.

How to delete a row in target when corresponding row in source is deleted
Greetings
Environment:
Repository - OWB 10.1.0.4 - going to 10gR2 very soon
- IBM RS6000 running AIX 5.3
I have a target table being updated with an INSERT/UPDATE. The user deleted a row in the source table and I want to delete the corresponding row in the target table.
How do I do this in the map?
Many thanks.
-garyThanks very much for the responses. Now that I have thought it through more carefully I see I can still have a single instance of the source table and send it through the MINUS operator with the target table followed by a DELETE into the target table and still have the existing logic for the INSERT/UPDATE into a second occurrence of the target table.
It won't matter what order OWB puts together the two operations on the target table:
- if it does the DELETE first the new rows that haven't been added to the target table will come out of the MINUS operator but not be found yet in the target table so not deleted.
- if it does the INSERT/UPDATE first the newly added rows will not come out of the MINUS operator and hence not deleted from the target.
Must have been a brain fart.
Thanks again.

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! -

How to delete a row in the table in servlets
I have met a problem in deleting a row in table using servlets.
My table looks like this:
ID Name Type
12 Milienium S
15 USIA O
My code looks like this:
String query = "SELECT * FROM tb_Funds";
rs = statement.executeQuery(query);
while(rs.next()) {
StdID=rs.getString("FundID");
StdName=rs.getString("Name");
StdType=rs.getString("Type");
out.print("<td><INPUT TYPE=TEXT NAME=
myName VALUE=" + StdID + "></td>");
out.print("<td>" + StdName + "</td>");
out.print("<td>" + StdType + "</td>");
buf.append("<td>" + "<INPUT TYPE=SUBMIT
NAME=Delete VALUE=DELETE>" + "</td></tr>");
There is a delete button in every row. May I know how to delete the row that I want by getting the ID from the table and delete it from the database.
Deleting from a table is simple -> delete from tb_funds where id = <value>. Obviously replace <value> with the appropriate ID or use a bind variable (a ?) and prepared statements.
Are you asking how to pass the id associated with the table row from the browser when the button is pressed? -
I am trying to delete a row from a JTable whenever the button on the last column is pressed. I know to do this, I can use the removeRow(int) method of the tableModel. But the odd thing is when I try to get a handle to the TableModel from the JTable to use that function, i.e. table.getModel().removeRow(int) it doesn't work.

deadseasquirrelsIt gives me a run-time error Well then your question should be "why do I get this run-time error" and then you would quote the error. Be more descriptive. "It doesn't work" is not descriptive.
table.getModel().removeRow(selectedRow);I don't use JDK1.5 either. But if you are saying that the above line compiles cleanly with JDK1.5 (because of the auto-boxing feature, or whatever its called), then I see no reason why the code wouldn't work since it recognizes the class as a DefaultTableModel.
Presumably you commented out the other line so you don't try to delete the row twice. Otherwise you might be getting a indexing error. -
Deleting a row from a database...
Here is the method I am calling to delete a row from a database. I keep getting this error, but I am not sure why.
Error: "Too few parameters. Expected 1."
//To delete a row
public void removeRow(String x, String y) {
try {
Statement stmt = con.createStatement();
//delete row with same x and y
//first is a string and second is a number
String query = "DELETE * FROM table WHERE first = '" +x+ "' AND " +
"second = " +Integer.parseInt(y);
int result = stmt.executeUpdate(query); //runs delete query, ERROR HERE *************
System.out.println("Test"); //debug statement, never gets here
//deletion confirmation message
JOptionPane.showMessageDialog(null, "Row deleted",
"Delete Reservation", JOptionPane.INFORMATION_MESSAGE);
catch (Exception e) { System.out.println(e); }Additionally, in the future you might want to use:
catch(SQLException sqlx) {
System.out.println( sqlx.getSQLState()
+"\t"+sqlx.getMessage()
+"\t"+sqlx.getErrorCode() );... It'll help with diagnostics.

JSP, BC4J, Row Tag: what is the best way to delete multiple rows?
Hi all.
I have a JSP Edit page with three datasources on it. The tables these VO's represent (A, B and C) have a Parent --> Child (1:1 between A and B) relationship and then another Parent --> Child (1:n between B and C) relationship. So the user retrieves one row for Table A, 1 matching row for table B and then between 0 and 6 matching rows for Table C (there cannot be more than 6 because the user can only add these rows from a finite list).
In my EditSubmit page, I want to perform a RowTag Update action on Tables A and B and they both work no problem. They can't update any rows from Table C but they can add or delete from the list of 0 - 6 rows (the UI is actually a list of 6 checkboxes that they can turn on or off). I figure that the easiest way to handle this rather than keep a list of original values and compare them is simply to delete all existing rows and then add any that the user checked.
This is causing a problem. I have added a hidden field to the form that picks up the RowKey for each existing row. I can get these RowKeys in the Submit page but cannot find a way of using them with the Delete Row Tag.
In the end, the only way I could get it to work was the following code (which I stole from the RowTag.java file in jbohtmlsrc.zip):
if (stakeMailRowKeys != null) {
for (int counter = 0; counter < stakeMailRowKeys.length; counter++) {
Key stakeMailKey = new Key(stakeMailRowKeys[counter], stakeMailingRS.getViewObject().getKeyAttributeDefs());
stakeMailRows = stakeMailingRS.findByKey(stakeMailKey,1);
stakeMailingRow = stakeMailRows[0];
// Tell the row to delete itself from the database
stakeMailingRow.remove();Is there a simpler way to do this (I figure there probably is)? I have another problem with updating the constrained View Objects but I will leave that out of this thread for now.
TIA,
SimonI don't know if this will help you, but this is what I do:
I separate the logic into a delete.jsp page. If you can create a View Object that will represent the rows you want to delete and append a where clause to select only the rows you want to delete. Then loop through the view deleting each row. Lets just say you have department and employee tables. and you want to delete employees within a given department. Create a view object that brings back all employees.
In your delete.jsp find out the department no. by request.getParameter("dept_id");
then append this to the where clause of your view Object and execute the query:
vo.setWhereClause(request.getParameter("dept_id");
vo.executeQuery;
now loop through and remove the rows:
while(vo.next){
vo.getCurrentRow().remove();
and commit or post changes accordingly.
There are many ways of doing this action. The easiest way I have found is to create the ViewObjects based on what actions you want to take on them. Make bc4j work for you.

Change array size and delete duplicate row
Hello,
I am running a program that does a for loop 3 times. In each loop, data is collected for x and y points (10 in the example provided). How can I output the array with the 30 points in a simple 2D array (size 2x30)?
Also, from the array, how do I delete duplicate rows that contain the same x-value?
Thanks,
hiNi.

array size.vi 10 KBHello,
THANK YOU for solving my first issue! Attached is the data set that contains the duplicate entries for the x-axis values. The y-axis value may be different, but not the x. I would like to delete the 2nd row that contains the same x-value.
Here is simple example of my input and desired output:
IN:
28.512000 -115.310532
28.812000 -86.937660
29.112000 -116.877052
29.412000 -87.223625
29.412000 -111.349045
30.012000 -86.510780
30.312000 -112.048187
OUT:
28.512000 -115.310532
28.812000 -86.937660
29.112000 -116.877052
29.412000 -87.223625
30.012000 -86.510780
30.312000 -112.048187
I am thinking of comparig the last x-axis value to the current one, and if it is the same, then not parse that row. The attached VI is as far as I got.
Any help will be greatly appreciated.
Thanks,

Delete empty rows while having empty xml tag
I've seen something like same but it doesn't work for me. I have a table which is created using xml rules, some time it contains empty xml tag also converted into row but I don't want these empty rows. After table creation empty rows need to be deleted.
I've got this script from this forum which delete empty rows
for(var i=myDocument.textFrames.length-1; i>=0; i--){
for(var j=myDocument.textFrames[i].tables.length-1; j>=0; j--){
for(var k=myDocument.textFrames[i].tables[j].rows.length-1; k>=0; k--){
myContents = 0;
for(var l=myDocument.textFrames[i].tables[j].rows[k].cells.length-1; l>=0; l--){
if (myDocument.textFrames[i].tables[j].rows[k].cells[l].contents != "") myContents++;
if (myContents == 0) myDocument.textFrames[i].tables[j].rows[k].remove();
but incase of any cell contains empty xml element it goes blank. Could any one help on this.
Thanks

JTable - trying to delete a row of data using an Abstract TableModel
Hi Guys,
I am trying to delete a row of data on a JTable. What I am trying to accomplish is to highlight the row by a mouseclick,
then from the menu bar I am having the user select a "delete row" option. I am working with an abstract
Table Model with a deleteRow method. I know I am doing something wrong in this method but I'm not sure what... it is not deleting nor dynamically reflecting the deleted row of data on the JTable gui:
P.S. I am using a Vector of Vectors to store the data
Here are snippets of my main class and Abstract Table Model :
Main Class
Table definition and mouse listener:
usermodel = new DataFileTableModel("UserCtl.dat") ;
userTable = new JTable();
userTable.setModel(usermodel);
userTable.createDefaultColumnsFromModel();
userTable.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent evt) {
upoint = evt.getPoint();
rowToBeDeleted = userTable.rowAtPoint(upoint);
Menu Selection which calls the deleteRow Method in the model:
deleteitem = new JMenuItem("Delete Row",'D');
editmenu.add(deleteitem) ;
deleteitem.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
int delresp = JOptionPane.showConfirmDialog(null,"Are you sure you wish to delete this row ?",null, JOptionPane.YES_NO_OPTION) ;
switch(delresp) {
case JOptionPane.NO_OPTION:
return;
case JOptionPane.YES_OPTION:
switch (tabnum)
case 0:
usermodel.deleteRow(rowToBeDeleted);
break ;
Here is my Abstract Table Model... the deleteRow method is at the bottom:

System.out.println("index = " + index) ;
for (int d = index; d <= colCount; d++)
data.remove(d) ;
fireTableRowsDeleted(rowNo,rowNo) ;Hi,
I can see one obvious problem. Your method to delete contains
for (int d = index; d <= colCount; d++)
data.remove(d) ;
which I think should be
for (int d = index; d <= colCount; d++)
data.remove(index) ;
because every time you remove the value at 'index' it replaces it with the value at 'index+1'.
I'm not sure that this is the only problem but ...

Problem of deletion of rows in jtable, table refreshing too
Hi,
I have a table with empty rows in the beginning with some custom properties( columns have fixed width...), later user would be adding to the rows to this table and can delete, I've a problem while deleting the rows from table,
When a selected row is deleted the model is also deleting the data but the table(view) is not refreshed.
Actually i'm selecting a cell of a row, then hitting the delete button.
So the model is deleting the information, but i'm not able to c the fresh data in table( especially when the last cell of last row is selectd and hit the delete button, i am getting lots of exception)
Kindly copy the below code and execute it, and let me know,

I've got the solution for it. As when the cursor is in cell of
a row and hit the delete button, the data in that cell is not saved,
So i'm trying to save the data first into the model then firing the action event by doing this ..
jButton2.addActionListener( new ActionListener(){
public void actionPerformed(ActionEvent actionEvent){
// If a button press is the trigger to leave a JTable cell and save the data in model
if(jTable1.isEditing() ){
String text=((javax.swing.text.JTextComponent)jTable1.getEditorComponent()).getText();
jTable1.setValueAt(text,jTable1.getSelectedRow(),jTable1.getSelectedColumn()) ;
jTable1.getCellEditor().cancelCellEditing();
// HERE DO THE DELETE ROW OPERATION

Advanced Table delete empty rows
Hi
I added logic to add 10 empty rows and to delete the empty rows when the form is submitted. But somehow it only deletes the rows in current screen of the Advanced Table. if there are 15 rows and I click next to go the last 5 and submit the form it deletes only the 5 empty rows but not the other 10 rows in the previous section.
where am I doing wrong?
Thanks
Row [] row = null;
ExpAttendeesVORowImpl rowi = null;
if( expattendeesvoimpl1 != null )
row = expattendeesvoimpl1.getAllRowsInRange();
System.out.println("No of items "+row.length);
for (int i=0;i<row.length;i++)
pageContext.writeDiagnostics(this, "in loop ", 2);
rowi = (ExpAttendeesVORowImpl)row;
pageContext.writeDiagnostics(this, " in loop row "+ rowi.getName(), 2);
if((rowi.getName() == null))
pageContext.writeDiagnostics(this, "deleting row"+ rowi.getName(), 2) ;
rowi.remove();
Thanksyou could instead try using:
expattendeesvoimpl1.getFilteredRows("Name", null);
