It's not my code, it's just Java.
C'mon, read the javadocs.

Changing column name in Line chart

Hello All,
We are BO 4.0 SP6.
We are creating WEBI reports which includes charts as well.
We have two columns " Current Period" and "Last Period" and using them in WEBI report and Line chart.
In the table I am displaying the column name " Current period " as "Oct-14" using some formula.
But I am not able to change the name in the chart.
Can we change the column name in the graph using some formulas? Please advice.
PFA the screenshot for your reference.
Regards
Prasad Ambati

Hi,
Do not Drag it inside chart area .
Align Them above Legend Text ( Current Period ),
so that Actual Legend Text will be hidden .

JTable column names with custom model

I'm having problems with column names in a JTable which uses a custom model. For some reason, the colums are being shown as A, B, C etc. The data, however, displays fine.
This is the code which constructs the table.
MyTableModel tableModel = new MyTableModel(myArrayList);
myTable = new JTable(tableModel);
myTable.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
myTable.setFillsViewportHeight(true);This is the class, MyTableModel
class MyTableModel extends AbstractTableModel {
        private ArrayList<Account> data;
        private String[] colNames = {"", "Name","Type","Group","Created","Modified"};
        public MyTableModel(ArrayList<Account> data) {
            this.data = data;
        public int getRowCount() {
            return data.size();
        public int getColumnCount() {
            return 6;
        public Object getValueAt(int row, int col) {
            Account account = (Account)data.get(row);
            switch(col) {
                case 0:
                    return account.getIcon();
                case 1:
                    return account.getName();
                case 2:
                    return account.getType();
                case 3:
                    return account.getGroup();
                case 4:
                    return account.getDateCreated();
                case 5:
                    return account.getDateModified();
                default:
                    return "";
        public String getColumName(int index) {
         System.out.println("N:"+colNames[index]);
            return colNames[index];
    }When the table is displayed, nothing's displayed to the console, but I'd have thought getColumnName would print the current column name. Am I missing something obvious?

Oh great. I'll go back under my rock.
Thanks =)

JTable, column names not appearing!

I am using the following code:
Vector columnNames = new Vector();
        Vector data = new Vector();
        try
            // Connect to the Database
            Common.Data.DataAccesser da = new Common.Data.DataAccesser();
            Connection connection = da.getConnection();
            // Read data from a table
            String sql = "Select * from schedule1";
            Statement stmt = connection.createStatement();
            ResultSet rs = stmt.executeQuery( sql );
            ResultSetMetaData md = rs.getMetaData();
            int columns = md.getColumnCount();
            // Get column names
            for (int i = 1; i <= columns; i++)
                columnNames.addElement( md.getColumnName(i) );
            // Get row data
            while (rs.next())
                Vector row = new Vector(columns);
                for (int i = 1; i <= columns; i++)
                    row.addElement( rs.getObject(i) );
                data.addElement( row );
            rs.close();
            stmt.close();
        catch(Exception e)
            System.out.println( e );
        // Create table with database data
        JTable table = new JTable(data, columnNames);
        jPanel2.setLayout(new java.awt.BorderLayout());
        jPanel2.add(table, BorderLayout.CENTER);I know its a bit messy, wat im tryin to do is add the table to the panel. the rows are showing perfectly but the column names do not show! Can anyone help?

1) Please ask Swing questions in the Swing forum.
2) Don't forget to specifically make the table header display. You do this by adding the table header to the jpanel in the borderlayout NORTH position, and you get the table header by calling getTableHeader. Have a look here for instance:

JTable Column Names Not Displaying

Hi there
I create a JTable by passing the JTable constructor my custom TableModel which extends AbstractTableModel.
For column names I have a String[] containing the column names in my custom TavleModel and have coded the TableModel methods accordingly.
For some reason when I run the code the table is displayed, but the column names are not!?!
Any advance is appreciated!

Sorted!
After looking at sample code in the JTable tutorial, it seems the table likes/needs to be added to a JScrollPane, as once I did this the column headings started appearing.
e.g. JScrollPane scrollPane = new JScrollPane(table);

Changing JTable column names

I have a JTable where the user can right click on the table header to change what data is displayed. When the user selects different data to display, I would like to change the column name to reflect this. What is the best way to do this?

Store Column-Name into variable

Hello from germany
I got stuck with following:
How is it possible to store the name of a column into a variable or is it possible to put an index "on" a column?
The reason for this: I need to fill and check a complete column!
Thanks for Your help!
Best regards

Those sure are unrelated questions. Lets say we have a table like this:
SQL> CREATE TABLE t (
2    a number,
3    b varchar2(8),
4    c date );
Table created.You can get a column name like this:
SQL> set serveroutput on
SQL> DECLARE
2    second_col   VARCHAR2 (30);
3 BEGIN
4    SELECT column_name
5      INTO second_col
6      FROM user_tab_columns
7     WHERE table_name = 'T'
8       AND column_id = 2;
9    DBMS_OUTPUT.PUT_line(second_col);
10 END;
11 /
B
PL/SQL procedure successfully completed.
SQL> You can put an index on a column like this:
SQL> CREATE INDEX t_n1 ON t(b);
Index created.And you can add data to the table like this:
SQL> insert into t(a, b) values (4, 'asdf');
1 row created.
SQL> select * from t;
         A B        C
         4 asdf

Easier way to set post-constructor JTable column names?

I have a class that extends JTable. It also has a pair of inner classes that extend DefaultTableCellRenderer and AbstractTableModel so I can dynamicaly adjust the number of rows and their contents. That's not the problem - that part works fine. The problem is the column headers. My table doesn't currently have any but I want to add them.
The column quantity is constant at 3 and should always be the same 3 Strings. It would be nice if I could use the JTable constructors that take a Vector or Object[] of column names from the start in my new class' constructor. But I don't think I can because at that point I don't know how many rows there will be or what they'll contain. Trying to set rowData to null just caused runtime exceptions.
So the alternative seems to be to call setColumnModel() within the constructor, passing it a DefaultTableColumnModel. Which then requires I call addColumn() three times. Each time passing it a new TableColumn object. Each of which requires that I separately call setHeaderValue() after I construct it to set the header name. Am I right in that is the only way to do it? It just seems overly complex.

I'll post a streamlined version of my class in case that will help...

UIX get EO column names into a messageChoice

I'm working on building a search function into my form which will allow the user to enter an arbitrary search string into a text box and then provides a list of columns in the table to be searched on. Is there any way to populate that list box (messageChoice) with the column names from the database dynamically? And if so, could I have the value set to those and the label set to the 'human readable' label text used on my forms?

Try looking at the section "Apply a filter to the Lov Window" here:

Get column names into a VB program, for an SQL query that joins tables

use [mydatabase]
select * from InvNum inum
left join _btblInvoiceLines ilin
on inum.autoindex = ilin.iinvoiceid
left join stkitem s
on ilin.istockcodeid = s.stocklink where InvNumber = 'IVQ0834' or InvNumber = 'IVQ0835'
I need to get out the column names in a VB program in the same order they would appear in the SQL query above...
I want to use something like:
select column_name from information_schema.columns where TABLE_NAME = ....
except there are several tables involved above so I dont know the format!

If you execute the query in your program using the SqlDataReader.ExecuteReader method, the column names will be available via the GetName method of the returned reader. But note that your query may return multiple columns with the same name.
Dim reader As SqlDataReader = command.ExecuteReader()
For x = 0 To reader.FieldCount - 1
Console.WriteLine(reader.GetName(x))
Next x

JTable Column Names

Hi, how can I change the names of the columns of a JTable that gets its data from a database;

Thanks mate, but I cannot use this constructor since my table automaticaly gets its data (what you declare as rowData) from an external database.
I found the solution to my problem to the next lines of code...
JTable table = new JTable;
TableColumnModel tcm = table.getColumnModel();
TableColumn tc = tcm.getColumn(0);
tc.setHeaderValue( "ABC" );
thanks anyway

Your question is not clear. Howver, this is what I guess you want to do.
Example, Check that the Emplyee Number I enter is KING. Check and Print message accordingly.
Here i user PL/SQL run in SQLPlus
SET VERIFY OFF
SET SERVEROUTPUT ON
DECLARE
     EMP_NAME VARCHAR(30);
BEGIN
     SELECT ENAME
     INTO EMP_NAME
     FROM EMP
     WHERE EMPNO = &EMP_NUMBER;
     IF EMP_NAME = 'KING'
     THEN
          DBMS_OUTPUT.PUT_LINE('The Emplyee Name is: '||EMP_Name);
     ELSIF EMP_NAME != 'KING'
     THEN
          DBMS_OUTPUT.PUT_LINE('The Emplyee is not KING but: '||EMP_Name);
     END IF;
EXCEPTION
     WHEN NO_DATA_FOUND
     THEN
          DBMS_OUTPUT.PUT_LINE('The Employee Number Entered is Invalid');

Jtable column name

Hi frds,
I developed a JTable for my java application and it is working fine but I need some modifications which i'm unable to do.my JTable is actually linked with mysql database and the data in Jtable comes from the database.my requirement is when i change data in the JTable, the change must reflect in the database.can u plz help me out..

hi,
if you have taken the data from the database,this means that you have no problem with java database connectivity.to inform the database you have to run some sql commands.
http://www.cab.u-szeged.hu/local/doc/pgsql/sql-commands.html
in the previous link you will find the sql commands.
i think that you want update,so click the hyperlink with the name update.
if something wrong is going wrong let me know.

How to call the column names into the prompt and display values dynamically

Hi,
i have a typical requirement where I have to call 3 columns into the AGE Prompt (I know we can use the Column Selector to call the columns) .Below is the Screen Shot.
!http://i46.tinypic.com/2qjfukh.jpg!
2nd Requirement)
The three columns I have are order Date, Ship Date and Entry Date.
Whenever I click on Orderdate from the Prompt, It should dynamically show its values in the report.
and When I click on the Ship Date from the Prompt, it should display the corresponding values in the report.
and so on with the Entry Date.
Can anybody help me how to acheive this.
Thanks a ton.

Ok so then you can use a fake column prompt. Here's one quick approach (nicer and cleaner with LOV tables but I don't if you have any of those).
- Create a fresh prompt using any column you want.
- Open the column formula using the fx button and replace the formula with 'abc'.
- Use "SqL Results" as the "Show" option.
- SQL:
select case when 1=0 the Markets.Region else 'Order Date' from Paint.Markets UNION ALL
select case when 1=0 the Markets.Region else 'Ship Date' from Paint.Markets UNION ALL
select case when 1=0 the Markets.Region else 'Entry Date' from Paint.Markets
- Set Variable = Presentation Variable = @{vPresVarSelectedDate}{Order Date}
- Label = Date
Then in the request, you change the column formula for the date. I'm going to make it short and just assume you called your time dimension alias(es) like the lowest grain:
"@{vPresVarSelectedDate}{Order Date}"."@{vPresVarSelectedDate}{Order Date}"
Cheers,
C.
