Col to row

How Can i convert the Columns In to Row in a oracle Select Query ?

If the data is like this...
CTRY DT WT
KSA     20-MAR-09     200
KSA     02-MAY-09     20
UAE     22-JAN-09     20
UAE     02-JAN-09     30
UAE     22-MAY-09     20
we can convrt the rows dt into columns like this (We have done month wise ..We can chage the query to do
data wise)
SELECT CTRY,
CASE TO_CHAR(DT,'MON-YYYY') WHEN 'JAN-2011' THEN SUM(WT) ELSE '' END AS 'JAN-2011',
CASE TO_CHAR(DT,'MON-YYYY') WHEN 'FEB-2011' THEN SUM(WT) ELSE '' END AS 'FEB-2011',
CASE TO_CHAR(DT,'MON-YYYY') WHEN 'MAR-2011' THEN SUM(WT) ELSE '' END AS 'MAR-2011',
CASE TO_CHAR(DT,'MON-YYYY') WHEN 'APR-2011' THEN SUM(WT) ELSE '' END AS 'APR-2011',
CASE TO_CHAR(DT,'MON-YYYY') WHEN 'MAY-2011' THEN SUM(WT) ELSE '' END AS 'MAY-2011',
CASE TO_CHAR(DT,'MON-YYYY') WHEN 'JUN-2011' THEN SUM(WT) ELSE '' END AS 'JUN-2011',
CASE TO_CHAR(DT,'MON-YYYY') WHEN 'JUL-2011' THEN SUM(WT) ELSE '' END AS 'JUL-2011',
CASE TO_CHAR(DT,'MON-YYYY') WHEN 'AUG-2011' THEN SUM(WT) ELSE '' END AS 'AUG-2011',
CASE TO_CHAR(DT,'MON-YYYY') WHEN 'SEP-2011' THEN SUM(WT) ELSE '' END AS 'SEP-2011',
CASE TO_CHAR(DT,'MON-YYYY') WHEN 'OCT-2011' THEN SUM(WT) ELSE '' END AS 'OCT-2011',
CASE TO_CHAR(DT,'MON-YYYY') WHEN 'NOV-2011' THEN SUM(WT) ELSE '' END AS 'NOV-2011',
CASE TO_CHAR(DT,'MON-YYYY') WHEN 'DEC-2011' THEN SUM(WT) ELSE '' END AS 'DEC-2011'
FROM TAB1
GROUP BY CTRY,TO_CHAR(DT,'MON-YYYY');

Has anyone been able to create a HtmlDataTable with dynamic col and rows?

Has anyone been able to create a HtmlDataTable with dynamic col and rows?
If so please explain. I am successfully able to dynamically add columns using the getChildren method of the htmldatatable object
BUT for each new column created no data is displayed.
I am only able to display data for columns originally created when i clicked and dragged the dataTable icon from the pallette in netbeans visual web kit.
Any help on this is greatly appreciated. I have been searching the web and these forums for around 8 hours and no one seems to have a working example of this. Lots of similar posts asking how to do it though :(
Thanks in advance.

6 rows selected.i want Query No.2 to be exactly returning the same number of rows, like Query No.1 - 8 Rows.
for example, in Query 1, there are 2 rows returned for product code P01033691.5 & P01033691.7,
whereas in Query 2 they are shown on single rows.
This is not the only case, the situaton may change where there can be more than 2 or just 1 values (in this case 11,12)
for SALEVH_DO_REF_NO Col. in Query 2.
i want to always break Col-to-Rows for Query 2,
based on the DOD_PROD_CODE & DOD_DOH_NO of Query 1 matching with SALEVD_PROD_CODE, SALEVH_DO_REF_NO of Query 2 .
so that it will become easier finally to use MINUS between both Queries like this;
Query 3
SELECT CUST_NAME, DOD_PROD_CODE, to_char(DOD_DOH_NO,999999) DOD_DOH_no,
to_char(DOH_SO_REF_NO,999999) DOH_SO_REF_NO

WHERE DOH_NO = DOD_DOH_NO
AND DOH_PARTY_CODE = CUST_CODE
AND DOH_SO_REF_NO = 13
MINUS
SELECT CUST_NAME, SALEVD_PROD_CODE, SALEVH_DO_REF_NO,
to_char(SALEVH_SO_REF_NO,999999) SALEVH_SO_REF_NO
FROM SALES_INVOICE_HEADER, SALES_INVOICE_DETAIL,CUSTOMER_MASTER
WHERE SALEVH_NO = SALEVD_SALEVH_NO
AND SALEVH_PARTY_CODE = CUST_CODE
AND SALEVH_SO_REF_NO = 13as per the above data the Query3 should not return any rows, but lets say a row gets added to Query 1 result,
i mean a new DOD_DOH_NO for the same DOH_SO_REF_NO. a 9th row for example;
ENERGY P01400012 13 13
and theres is no Invoice done, then Query 3 should return just 1 row which is just the above 1, the 9th row.
any help will be highly appreciated. TY

Mr. Massimo,
Your Query MUST return rows and those should be the following 8 rows;

Suppress COL and ROW based actual period and previous one

Hi!
Here is a problem I am trying to solve:
Lets say you have in COL a list of products and in ROW a list of client.
Most of the products bought by the client are the same month after month...
Most of the clients are the same month after month...
So I would like my COL to suppress depending on period N and period N-1 because my products hardly change. To add a new one, I will put the INSERT = Y in my expansion.
I would like my ROW to suppress depending on period N and period N-1 because in the long list of my clients, only some of them buy my products. To add new clients, I will put the INSERT = Y in my expansion.
I hope the definition of my problem above is good, here is how I try to solve it in my EVDRE;
PARAMETER     EXPANSION 1                |             EXPANSION 2
ExpandIn           ROW                |             COL
Dimension          Product               |             Client
MemberSet         basmembers                |             basmembers
BeforeRange                             |
AfterRange                                |
Suppress          [2009.JAN,2009.FEB ] |             [2009.JAN,2009.FEB]
Insert                       y                |               y
It doesnt work!
When I have data in January, and I check February the expansion returns totaly empty!!
Thanks for your help

How to change colors of table col and row header?

Could I change table header colors when run vi ? Is such a thing possible?
ex: Header words color from black changed to green in column 2 of table.

cloud a écrit:
...But I mean is "How to change header words color" not changed cell words color.
tst gave you the answer ! A header cell is just a cell with a -1 value as index...

I guess (but not sure) - will UNPIVOT function help in achieving this.
I'm refering this - http://www.oracle-base.com/articles/11g/pivot-and-unpivot-operators-11gr1.php#unpivot but not able to figure out its exact usage.
Could you please help me with this?
Help much appreciated.

Just formatted your query:

    UNPIVOT(
      val for q in(q1, q2, q3, q4)
PIVOT( max(val) for store in('shop1' sh1, 'shop2' sh2)
first we are unpivoting your data :
select store, q, val from t
    UNPIVOT(
      val for q in(q1, q2, q3, q4)
val is the virtual column name for unpivoted data (you can gave any name)

Then we need pivot data for column store and for this in inline view we pivot data :
select * from (
select store, q, val from t
    UNPIVOT( val for q in(q1, q2, q3, q4)
PIVOT( max(val) for store in('shop1' sh1, 'shop2' sh2));

Changing background color in JTable, only changes one row at a time...

I'm trying to change the color of rows when the 5th column meets certain criteria. I think I'm very close, but I've hit a wall.
What's happening is the row will change color as intended when the text in the 5th column is "KEY WORD", but when I type "KEY WORD" in a different column it will set the first row back to the regular colors. I can easily see why it's doing this, everytime something is changed it rerenders every cell, and the listener only checks the cell that was just changed if it met the "KEY WORD" condition, so it sets every cell (including the previous row that still meets the condition) to the normal colors. I can't come up with a good approach to changing the color for ALL rows that meet the condition. Any help would be appreciated.
In this part of the CellRenderer:
        if (isSelected)
            color = Color.red;
        else
            color = Color.blue;
        if (hasFocus)
            color = Color.yellow;
        //row that meets special conditions
        if(row == specRow && col == specCol)
            color = color.white; I was thinking an approach would be to set them to their current color except for the one that meets special conditions, but the two problems with that are I can't figure out how to getColor() from the table, and I'm not sure how I would initially set the colors.
Here's the rest of the relevant code:
    public void tableChanged(TableModelEvent e)
        int firstRow = e.getFirstRow();
        int lastRow = e.getLastRow();
        int colIndex = e.getColumn();
        if(colIndex == 4)
            String value = (String)centerTable.getValueAt(firstRow, colIndex);
            // check for our special selection criteria
            if(value.equals("KEY WORD"))
                for(int j = 0; j < centerTable.getColumnCount(); j++)
                    CellRenderer renderer =
                        (CellRenderer)centerTable.getCellRenderer(firstRow, j);
                    renderer.setSpecialSelection(firstRow, j);

}If I'm still stuck and more of my code is needed, I'll put together a smaller program that will isolate the problem tomorrow.

That worked perfectly for what I was trying to do, but I've run into another problem. I'd like to change the row height when the conditions are met. What I discovered is that this creates an infinite loop since the resizing triggers the renderer, which resizes the row again, etc,. What would be the proper way to do this?
Here's the modified code from the program given in the link. All I did was declare the table for the class, and modify the if so I could add the "table.setRowHeight(row, 30);" line.

Comboboxes are not set on the 1st time a row is clicked in the dataTable

I have somewhat the following setup:
I have a DataTable that is filled with a listof objects, a actionListener is handeled when a row is clicked.
Under the Table there are two ComboBoxes (lets call them Category and Item) that get their values from lists of Objects. The values of the list that backs the Item combo depend on the selected value of the Category combo.
Lets assume the values look like this:
CategoryA
---ItemA1
---ItemA2
CategoryB
---ItemB1
---ItemB2
Together with some textboxes, they should represent the values of the clicked row in the Table.
Now the problem:
When the comboboxes have a different value than the row that is beïng selected the values of the comboboxes and textboxes are not set correctly until the 3rd time the row is clicked.
It also doesn't go into the onClickMehod in the backing bean before the 3rd click. This is checked by a logger.
an example:
before clicking, the category combo is set to "CategoryB", the Item combo is set to "ItemB1" and the textboxes are empty. The row that is going to be clicked has as its category "CategoryA" and as its Item "ItemA1"
1st click:
the form still shows the values like they were before clicking, the log doesn't show that the method is triggered
2nd click:
the Item combo is set to "ItemA1", the category is still set to "CategoryB", the textBoxes are still empty. The log still doesn't show that the method is triggered
3rd click:
the Category combo is set to "CategoryA", the Item combo is set to "ItemA1", the textboxes also have their correct values.
the code is as followed:

}I've already tried to use the action attribute instead of the actionlistener attribute, also tried to add immediate="true" to all fields and columns.
Did try to add onclick="submit();" to the rows.
What can be done to fix it??
ps: the enviroment is JSF + Spring + Hibernate

The <h:messages/> tag is where the validation exception is shown, but no validation is used on the form, no other exeptions are sown.
the List<Categories> is filled at a setPageLoad method which is bound to the form by <h:form binding="#{backingBean.pageLoad}">.
The List<SelectedItem> of the categories box is filled in its getter and filled with the values of the List<Categories>
And both the List<SelectedItem> of the items box and the List<Item> are filled in the getter of the List<SelectedItem> of the items box
so instead of that i should rewrite it to something like this:
public BackingBean() {
    selectedCategories = new List<SelectedItem>();
    selectedItems = new List<SelectedItem>();
    categories = CategoryService.retrieveCategories(); //gets all categories
    items = ItemService.retrieveItemsByCategory(selectedCategory); //gets the items
    for (int count = 0; count < categories.size(); count++) {
        selectedCategories.add(new SelectItem(categories.get(count).getId(),categories.get(count).getDescription()));
    if (selectedCategory == 0){
        selectedCategory = categories.get(0).getId();
    for (int count = 0; count < items.size(); count++) {
        selectedItems.add(new SelectItem(items.get(count).getId(),items.get(count).getDescription()));
    if (selectedItem == 0){
        selectedItem = items.get(0).getId();
public void CategoryChange(ValueChangeEvent vce){
        try {
            if (vce.getPhaseId() != PhaseId.INVOKE_APPLICATION) {
                vce.setPhaseId(PhaseId.INVOKE_APPLICATION);
                vce.queue();
            } else {
                FacesContext.getCurrentInstance().renderResponse();
                selectedCategory = Integer.parseInt(vce.getNewValue().toString());
                category = CategoryService.retrieveCategoryById(selectedCategory); // gets the category Object
        } catch (Exception e) {
            logger.error("Error occured: {}",e.toString());
            FacesContext context = FacesContext.getCurrentInstance();
            context.addMessage("ERROR", new FacesMessage(e.toString()));
public List<SelectItem> getSelectedCategories() {
    return selectedCategories;
public void setSelectedCategories(List<SelectItem> selectedCategories) {
    this.selectedCategories = selectedCategories;
public List<SelectItem> getSelectedItems() {
    return selectedCategories;
public void setSelectedItems(List<SelectItem> selectedItems) {

SSIS : Read Rows from an Object variable in SSIS Script Task which is looped many times.

Hello All,
Here is what I am trying to do...
1. I am having two rows, one column in an Object Variable. (vLoopCountObj).
2. I am having 30 Rows, 2 Columns in my second Object Variable (vTableRowsObj)
3. I have a FOR EACH LOOP which will run for number of rows in vLoopCountObj i.e 2 times here.
4. I have a Script Task inside the FOR EACH LOOP to display all the rows of vTableRowsObj.
5. When I execute, 30 Rows gets displayed only once. It will not display when the loop goes for second iteration. Please help me to display for second time.
6. I have used below code to display the rows whithin the script task which is in SSIS dataflow task.

Hi Raj,
It is verrrry interesting issue. I can also confirm that it doesnt loop again. I've made a simple test and figured that in the second loop even you fill the Dataadapter, record count is zero. Which brings me up to the idea: Somehow, after you read the object
variable resultset, you can not read it again in the for each loop.
Strange, probably a bug or a technical issue that is beyond my existing knowledge.
I can provide a workaround. You can also loop in script task for first variable. (Nested loops)
Let other members to examine and comment on this.

How can I add rows to a JTable based on an Abstract Table Model?

I have done this ...
public class myui extends JPanel {
private AbstractTableModel jTable1Model;
blah blah
        jTable1Model = new AbstractTableModel() {
             String[] column = new String[]{"TID", "Name", "Address"};
             Vector<Vector<Object>> table = new Vector<Vector<Object>>();
             @Override
             public int getRowCount() {
                  return table.size();
             @Override
             public int getColumnCount() {
                  return column.length;
             @Override
             public String getColumnName(int col) {
                  return column[col];
             @Override
             public Object getValueAt(int row, int column) {
                  return table.get(row).get(column);
             @Override
             public void setValueAt(Object value, int row, int column) {
                  table.get(row).set(column, value);
                  fireTableCellUpdated(row, column);
             public void insertRow() {
                  Vector<Object> columns = new Vector<Object>();
                  columns.add(null);columns.add(null);columns.add(null);
                  table.add(columns);
                  fireTableRowsInserted(0, table.size());
blah blah
    public synchronized void ImportVisitorDataToJTable1(Object value, int row, int col) {
        jTable1Model.InsertRow(); <-----///// This line not being recognised as a valid member function call
     jTable1.setValueAt(value, row, col);
}I thought to insert a row I can define a function in the abstracttablemodel class and then instantiate the class and override or create new methods that I can use.
But after instantiating the class and overriding appropriately and adding the insertRow function, when I try to use it in ImportVisitorDataToJTable1 as seen above its not being recognized as a funtion of jTable1Model

1. respect naming conventions. Example: myui --> MyUI, ImportVisitorDataToJTable1 -->importVisitorDataToJTable1
2. convert Anonymous to Member: AbstractTableModel --> MyTableModel
3. row parameter makes no sense here as it depends on current row count:
    public synchronized void importVisitorDataToJTable1(Object value, int col) {
        int row = jTable1Model.getRowCount();4. here is a more adequate "fireTable.."-call for insertRow:
fireTableRowsInserted(table.size() - 1, table.size() - 1);
5. check if you can take advantage using DefaultTableModel as suggested by Maxideon.

select sum(num_rows)
from sys.dba_tables
where owner like '%%'
i obtain the number of all rows for all schema in database.
I have many database, i use agent g10.0 and enterprice manager to query them.
I
've seen that in Enterprise Manager, when you select a Database Istance, then go on "administration" tab, and u click on TABLES link, you can see number of rows and last time the table was analyzed. How are they have been calculated? With table dba_tables? How can i query to obtain these values?
I know it's a stupid task but my boss wants this info :(

> I know it's a stupid task but my boss wants this info :(
Tell him two gazillion. Also tell him that the gazillion scale has been specifically created for managers like him with heads firmly stuck up the back side.
Anyway, here's some sample code. Note that you cannot use DBA_TABLES view. Object tables are not listed in there and they can contain rows (obviously). There is also the case of dealing with case and "weirdly" names tables - thus double quotes are needed.
I only did the first 10 tables.. It is stupid to just one, never mind all of them in database...

Double click on a JTable row.

I got and run a sample about double click on a JTable and it works fine. This sample defines a TableModel as shown at the end this note.
On the other hand, I have an application in which I have defined a JTable
using the DefaultTableModel as follows :
DefaultTableModel dtm = new DefaultTableModel(data, names);
JTable table = new JTable(dtm); where data and names are String arrays.
Of course the mouse listener stuffs have been also specified.
table.addMouseListener(new MouseAdapter(){
     public void mouseClicked(MouseEvent e){
      if (e.getClickCount() == 2){
         System.out.println(" double click" );
     } );Because the difference with the sample was the table model,
I changed it with the DefaultTableModel class. At this point, the Double click does not work anymore.
So I gues it should be an option which prevents double click to work.
I thought of using mousePress() instead of mouseClick(), but it's very dangerous (I tried). . If by error the user clicks twice (instead of only once) the mousePress method is invoked twice for the same entry
My question is now simple, may I use double click on a JTable with the default table model. If so, what I have to do ?
Thanks a lot

How to change the row position in a datatable

I am storing my list of lists in a datatable :
DataTable table = new DataTable();
for(int i = 0; i < info.Count; i++)
table.Columns.Add(names[i]);
for(int col = 0; col < info.Count; col++)
for(int rows = 0; rows < info[col].Count; rows++)
DataRow r = table.Rows.Add();
r[names[col]] = info[col][rows];
However the problem is that it is stored diagonally. Meaning that the first column is shown on rows 0-3, the second column 4-7 and so on. I want all the columns to be stored in positions 0-3. How can I do that ?

"What would you suggest instead of datatable? I just want to show info of my lists that's all."
Show in a control such as the WinForms's DataGridView or something similar?
If you do not known the number and type of columns in advance then yes, using DataTable is a convenient way to do that as binding the grid to the list of lists won't work. Well, if the number of rows you can consider populating the grid control directly.
If you do know the number and type of columns it's in general preferable to create a class to hold the information that corresponds to a row and then use a list of objects of that class. That list can easily be displayed in a grid control.
