How to get the column index inside a dataTable

Hello,
before I get staked, there are multiple threads handling familiar topics to the one I'm questioning about but none gives an anwer. If there is one, I'm propably to less skilled to see it.
So here is my Problem: I've build a web-interface to a time-recording system. The hours worked on a certain project are displayed in a dataTable component which is generated out of a mySQL Query. Each entry (column/row) contains a inputText component to display and edit the specific value.
Editing one of these inputText elements now fires a valueChangeEvent which reads the new value and stores it in the database. For that cause I need to know the row- and column-index of the inputText component that fired the event.
Using the getClientId method from the valueChangeEvent I get some Information which makes it possible to calculate the row/column index. A typical clientID looks like "form_table:mainTable:0:_id14". "form_table" is the ID of the form the dataTable is in. "mainTable" is the id of the dataTable component. "0" is the row the component is in. And finally "_id14" stands for the id randomly given to the inputText component by JSF.
My Problem is now, that though I can calculate the column out of the[i] "_id14", this calculation is hardcoded. So everytime I add a component in before the dataTable, the calculation needs to be adjusted in the code.
The Questions:
- How to force a sensefull id indicating a column-index for the inputText components inside the columns of a dataTable?
- Nicer since no workaround: How to get the column-index inside the dataTable on a natural way? (e.g. out of the valueChangeEvent the specific inputText component fires)
After some investigation here on the board and on the net I know multiple ways to get the row index, (Things like component-binding and so on) but I can't find a answer on how to get the column-index.
Thanks to all answers and/or links to things my eyes missed while searching for one.

...then index 0 becomes index 1 and my program doesn't work properlyThe program works properly, just not as you expect it to.
As you've noticed the table gives you the flexibility to move columns around. So if you move column 0 to column 1, why would you expect to still use 0 as the index? The table manages the reordering of columns for you to make sure the data being displayed in each table column comes from the correct column in the data model.
You can manage this yourself using one of the following methods (I forget which one):
table.convertColumnIndexToModel(int viewColumnIndex)
table.convertColumnIndexToView(int modelColumnIndex)
Or, you can get data from the data model directly:
table.getModel().getValueAt(row, 0);

Hey john,
My requirement is as follows
I have created a Rank for Total sales by Region wise i.e RANK(SUM(Dollars By Region)) in a pivot table.
My pivot table looks like this
COLUMN SELECTOR: TOTAL US , REGION , DISTRICT , MARKET
---------------------------------------------------- JAN 2009          FEB 2009        MAR 2009
RANK              REGION                  DOLLARS           DOLLARS        DOLLARS DOLLARS
1 CENTRAL 10 20 30 40
2 SOUTHERN 10 30 30 70
3 EASTERN 20 20 20 60
4 WESTERN 10 20 30 40
When i select the District in column selector
Report has to display rank based on Total Sales by District. i.e
------------------------------------------------- JAN 2009         FEB 2009       MAR 2009
RANK             DISTRICT              DOLLARS           DOLLARS        DOLLARS DOLLARS
for this i need to change the fx of rank i.e RANK(SUM(Dollars By Region)) to RANK(SUM(Dollars By District)) and fx of Region i.e Markets.Region to Markets.District dynamically.
so , i need to capture column name of the value selected from the column selector and dynamically i need to update the fx 0f RANK & fx of region.
do you have any solution for this?

How to get the column count at the bottom of the column

Hi Friends,
How to get the column count at the bottom of the column
Thanks
Raj

You mean row count? Add another column, click on the fx button and type RCOUNT(1).
If you want just the total you can make it MAX(RCOUNT(1)), hide this column and then add a Narrative View after your report and enter "Total Number of Records: @n" where "n" represents what order your column is from the left side.

How to get the column values

hi
i am new to programming... i would like to know how to get the column values... i have a resultset object
i need code .... asap
thnx

@OP: It is always good to type complete sentences and describe your problem at length. It helps in letting people know what you really need instead of making wild guesses or silly jokes. You post mentions that you get the ResultSet. Then you should look up the API docs for java.sql.ResultSet and take a look at the getxxx() method signatures. Use the ones which suit the specific case.
Besides, it is good to refrain from using asap and urgent. Even if something is urgent to you, it need not be urgent to others. Wording a question properly would attract better replies.
Finally, would you mind getting down to specifics of your problem? From what I perceived, the JDBC tutorial and the API docs should provide all the information you need.

How to get the column values from a BC4J View Table in UIXML?

I am using a default UiXML Application for Order Entry system with Orders & Order Lines & Customers. I have a uix file OrdersView1_View.uix which displays (no updateable columns) all the Orders. How do I get the column value of a selected row in a BC4J Table (example:OrdersId) when a Submit button is pressed using UIXML or Java Classes?
I appreciate any help on this.

Hi,
You need to use keyStamp, an example:
<bc4j table name="orders">
<bc4j:keyStamp>
<bc4j:rowKey name="key" />
</bc4j:keyStamp>
Furthermore, you can automatically send the selected row key using the go event handler, so in the handlers section you could send the key to an orderInfo page:
<event name="show">

<ctrl:go name="orderInfo" redirect="true">
<ctrl:property name="key">
<ctrl:selection name="orders" key="key" />
</ctrl:property>
</ctrl:go>
</event>

How to get the Column names of output that is displaying in Sql Developer(Oracle 11g).

Hi,
    I am using OCCI to interact with DB through code, which means I am writing a vc++ file to interact with Data Base and execute the Stored Procedure which I am calling from the C++ Code. And also displaying the output of the Stored Procedures to the Front End. I am succeeded in this, but now I should be able to display the Column names of the output to Front End. Can any one help me on this.
Example:
Sno |   Sname
------- |-------------
1          ABC
2          DEF
I am getting (1,ABC) and (2,DEF) as the output of the Stored Procedure but I need the Column names also to display. How to get them.
Thanks in Advance..:)

Look at Re: exporting csv via pl/sql - select statement?
It has an example how to extract the column name from a cursor. You have to check, whether you can use DBMS_SQL.DESCRIBE_COLUMNS
Your procedure might need another out parameter, that returns the column names , e.g. as comma separated list or as varray.

Reading csv file how to get the Column name

Hi,
I am trying to read a csv file and then save the data to Oracle.
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection c = DriverManager.getConnection("jdbc:odbc:;Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=.;Extensions=csv,txn");
Statement stmt = c.createStatement();
ResultSet rs = stmt.executeQuery("select * from filename.csv");
while(rs.next())
System.out.println(rs.getString("Num"));
My csv file looks like this:
"CHAM-23","COMPANY NAME","Test","12",20031213,15,16
Number,Environ,Envel,Date,Time
"1","2",3,"4",5
"6","7",8,"9",9
Now is there anyway using the above code I start processing the file from the second row that holds the names of the columns and skip the first row. And also can I get the name of the column using ResultSet something like:
if columnName.equals("Number")
Because I may have a csv file that could have more columns:
"CHAM-24","COMPANY NAME","Test","12",20031213,16,76
Number,Environ,Envel,Date,Time,Total,Count
"1","2","3","4","5",3,9
"6","7","8","9",9",,2
So I want to get the column name and then based on that column I do some other processing.
Once I read the value of each row I want to save the data to an Oracle Table. How do I connect to Oracle from my Application. As the database is on the server. Any help is really appreciated. Thanks

The only thing I could think of (and this is a cluj) would be to attempt to parse the first element of each row as a number. If it fails, you do not have a column name row. You are counting on the fact that you will never have a column name that is a number in the first position.
However, I agree that not always placing the headers in the same location is asking for trouble. If you have control over the file, format it how you want. If someone else has control over the file, find out why they are doing it that way. Maybe there is a "magic" number in the first row telling you where to jump.
Also, I would not use ODBC to simply parse a CSV file. If the file is formatted identically to Microsoft's format (headers in first row, all subsequent rows have same number of columns), then it's fine to take a shortcut and not write your own parser. But if the file is not adhering to that format, don't both using the M$ ODBC driver.

from Employe
group by dob.
I want to generalize the query like get the columns from SYS.ALL_COLUMNS table for that table name and want to pass it to COALEACE() function. I tried with Cursor. But i didnt get the appropriate results.

How to get the tree index of a child node

Hi, I am loading a tree object from an XML source file (via
an XMLListCollection)
I can find the children on the currently selected node, like:
var children:XMLList =
XMLList(myTree.selectedItem).children();
for(var i:Number=0; i < children.length(); i++) {
trace("Child Found: " + children
.@caption);
But how can I determine the tree index for each of the
children? I would like to be able to grab and save the tree index
for each child, so that I can later just to do
"myTree.selectedIndex = (saved child index) (based on some form
action the user performs). I can't find any method of determining
what the tree index for a child is, other than walking down the
tree from the parent node and counting the number of nodes till I
hit each child. Is there a simple method?

Tree is hierarchical, index is linear. I have never seen
anyone successfully use selectedIndex with Tree.
You best bet is to put an id on each node and use e4x
expression to find that node when you want.

Connecting my ipad to itunes, how to get the columns there

hi all!
I'm sure its been discussed before but couldnt find the topic with a quick search, so I'll start a new one, sorry for that.
My problem is quite simple, when I connect my ipad mini on itunes, I can't show the columns browser (artist, album etc). the line to put it is just grey. Is there any way to activate it? It's just way easier to browse my music with it!
thx in advance pple!

Hi Jamalzoal,
Dose your computer have the most recent iTunes on it? When you connect the iPad 2 to your computer what happens? dose iTunes tell you the iPad need to be restored?
p.s. you post this question in the Apple Remote Desktop community. You would probable have gotten more an fast responses if you posted this in the iPad community.

How to get the Date format inside the table

I have a startdate column in the db in the format May 5, 2001 12:39:00 PM, when I query it from a view in this way : SELECT startdate, ... FROM ..., it returns the format in the db,
However I have to do this SELECT
decode(startdate, null, 'NOT START'), startdate), ... the result is 5-MAY-01,
then I tried this to_char(startTime, 'Month DD, YYYY HH:MI: A.M.') the results become May 05, 2001 12:39:00 PM. (more space between month and day, and 05 instaed of 5)
Does anybody know how to fix this, so I get exactly what is in the db?
Thanks in advance

No matter what you do if you are storing a date in a column it will get stored in the Oracle's internal 7 byte date format.
The way you get it on retreiving it is as set by your date format. You can either change the default date format for the instance, the individual session or the individual SQL statement(in this case using to_char(date, 'format')).
If you want to store the date in a format you want to store you'll have to store it as char or varchar2.

then I tried this to_char(startTime, 'Month DD, YYYY HH:MI: A.M.') the results become May 05, 2001 12:39:00 PM. (more space between month and day, and 05 instaed of 5)
Does anybody know how to fix this, so I get exactly what is in the db?
Thanks in advance<HR></BLOCKQUOTE>
When you do to_char() with 'month' oracle blank pads the month to nine characters, the same goes with day too. So to get rid of it you'll have to trim() the month. And if you want to get a single digit for date less than 10 instead of 0x you'll have to do a bit of extra jugglery using translate() or replace().
Hope this helps
