How to get Number of columns in a table?

Hi all, just starting with database connectivity.
I was wondering if there is any method where I can get the no. of cols in table at run time. I tried the ResultSet rs; but rs doesn't seem to have any method that will get the no. of columns.
Any pointers to this is greatly appreciated?

You can use the getColumnCount() supplied by
the ResultSetMetaData class, an instance of
which can be obtained using the getMetaData()
method of the ResultSet instance itself.
I hope this will help.
ByeThanks a lot for the quick input. It really helped me a lot to create tables based on the no of cols retrieved.
Thanks again!!

Thanks SreeKanth

Hi,
looks like you are on Infomation Builders, correct? If yes through which adapter and to what DB are you connecting?? in an R3/BW system you can do the folowing:
"(ABAP)
SELECT DISTINCT FIELDNAME
FROM DD03L
WHERE TABNAME = '/BIC/QPERSON'
AND AS4LOCAL = 'A'
AND KEYFLAG = 'X'
ORDER BY 1
Another option is goto directly to the RDBMS; in this case let me which one are you using
hope this helps...

How to get invoice status column in ap_invoice_all table

how to get the invoice_status column like "NEEDS RE VALIDATION" in account payables tables.

The invoice approval status does not come from any table / lookup.
Instead, Oracle builds it by calling the ap_invoices_pkg.get_approval_status function.
You can also call it by passing invoice_id, payment_status_flag and invoice_type_lookup_code.
All these 4 columns are present on the ap_invoices_all record.
Hope this helps

How i get number of record in repet frame?

Hi,
How i get number of record in repet frame?
Regards
Jomar

Jomar,
you can use Summary Columns in the Data Modell. Create them on group higher that your wished group (so on the pane for an first group of a query), use as Source the primary column and as reset at the group, where the summary column is located.
If you hide some instances via format triggers, that you could use a counter inside the format triggers to count the rows.

How to get number of rows return in SELECT query

i'm very new in java, i have a question:
- How to get number of rows return in SELECT query?
(i use SQL Server 2000 Driver for JDBC and everything are done, i only want to know problems above)
Thanks.

make the result set scroll insensitve, do rs.last(), get the row num, and call rs.beforeFirst(), then you can process the result set like you currently do.
         String sql = "select * from testing";
         PreparedStatement ps =
          con.prepareStatement(sql,ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
         ResultSet rs = ps.executeQuery();
         rs.last();
         System.out.println("Row count = " + rs.getRow());
         rs.beforeFirst();~Tim
NOTE: Ugly, but does the trick.

How to get the dynamic columns in UWL portal

Hi All,
I am working on UWL Portal. I am new to UWL. I have down loaded uwl.standard XML file and costomized for getting the values for "select a Subview" dropdown and I am able to see the values in the dropdown. Now my requirement is to get the dynamic columns based on the selection from dropdown value.
can any body suggest on how to get the dynamic columns in UWL portal.

Hi Manorama,
1) If you have already created a portal system as mentioned in following blog
/people/marcel.salein/blog/2007/03/14/how-to-create-a-portal-system-for-using-it-in-visual-composer
2) If not, then try to create the same. Do not forgot to give the Alias name .
3) After creating a system, log on to the VC, Create one iView.
4) Now Click on "Find Data" button from the list which you can view in right side to Visual composer screen.
5) After clicking on "Find Data" button, it will ask for System. If you have created your system correctly and Alias name is given properly, then your mentioned Alias name is appeared in that list.
6) Select your system Alias name and perform search.
7) It will display all the BAPIs and RFCs in your systems.
8) Select required BAPI and develop the VC application.
Please let me know if you any further problems.
Thanks,
Prashant

How can I find number of columns in a table using a query

Hi
I want to find the number of columns in a table using a query.
Any help in this regard is much appreciated.
Cheers

Hi,
This is the output i get when i executed ur query
OWNER OBJECT_NAME OBJECT_TYPE
SMLDBO T2311_SURVEY_QUESTIONS TABLE
select OWNER,OBJECT_NAME,OBJECT_TYPE
from all_objects
where OBJECT_NAME = 'T2311_SURVEY_QUESTIONS';
works Fine.
But if i use the below query it returns : 0
SELECT count(*) FROM user_tab_columns
WHERE table_name =upper( 'T2311_SURVEY_QUESTIONS');
What could be problem.
The table exists + name of the table is correct + it resides in my schema itself.
Any guess !!!

Edit:
Dear thread users!
You have here (in my post in this thread - see above) good example for inappropriate post in one thread.
I posted to fast - I didn't realise am I sure what I wrote!
Consequence was that, after posting, I asked myself is it correct my statement about rights on SYS-objects, I started to search for answer, etc.
So what I want to say is: if you don't want to find yourself foolish, like I found myself, don't post before you are sure is it correct what you wrote!

if you carefully look inside the form field's you will find the logic of sort . if you remove that you will get the data without any sorting order.

Hi,
I'm not sure if I understood what are you trying to do. But you can modify your table in a backing bean code. JSF page code for a table:
<af:table id="product_search_results_tbl" binding="#{backingBean.boundTable}" ... />
And a backing bean code:
import oracle.adf.view.faces.component.core.data.CoreTable;
public class YourBackingBean {
    private CoreTable boundTable;
    public void setBoundTable(CoreTable boundTable) {
        this.boundTable = boundTable;
    public CoreTable getBoundTable() {
        return boundTable;
   public String insertButtonAction() {
      // Bind your button action to this method and modify here your bound table
     return null;
{code}
Look for column modification methods in a CoreTable class documentation.
