A JDBC tutorial would really help you out. You can find one at:
http://java.sun.com/developer/onlineTraining/Database/JDBC20Intro/JDBC20.html
If your too busy (or lazy) to take the tutorial, this might get you going:
A ResultSet is initially positioned BEFORE the first row. You need to move to the first row most commonly done using rs.next()
rs.isFirst() returns a boolean that is true IF you are on the first row. You don't seem to be using it that way...
Good Luck!

FWD: Re: Retrieving multiple rows from a database into morethan

There are two ways to do this that I cn think of right off the bat.
One is to create a class of objects that can receive the entire row, and
give it methods that will return each of the individual objects that you are
looking for when called. If you use INTO :ARRAY, you get the advantage of
being able to pass the array anywhere in your system for the 'split up'
processing.
Two is to do basically the same thing, but instead doing the 'split up'
during a for loop. This will appear to slow down your query, however, as
extra processing will be occuring in terms of memory allocation and copying.
I'm sure there other approaches. This was simply what came to mind at
midnight, after a long day :-).
At 01:33 AM 6/4/96 +0000, you wrote:
Does anyone know of a way to retrieve multiple rows from a single table in an
RDB database into more than 1 object, using a single SQL call?
I have a single table that I wish to use some fields to populate one object
and some others to populate another.
The FOR clause only allows one object to be specified.
The INTO :ARRAY clause also seems to only allow one object to be specified.
I would appreciate any help.

Newbie wants to remove first name from cell that contains "FIRST LAST"

Any help is appreciated, I'm pretty much a complete newb with a spreadsheet. I have a sheet with sales prospects. One cell has the the full name in a cell, i.e. "John H. Doe". Some of the cells have a period after the middle initial. Some cells have no middle initial. What I am wanting to do is to create a new cell that only contains the first name. If it makes it any easier, I do have another cell that contains only the last name. When explaining how to do this, I ask that you dumb it down for me! I have about 850 rows. I'll need instructions completely in steps. I don't know how to apply a function to a new column. Thanks in advance! I know I'm asking alot.

BT,
It would help you to get acquainted with Numbers if you read the User Guide PDF. It's written at a beginner level, not like a reference manual.
This solution assumes that the full name is in column A. If not, you can substitute your true column for the "A"s in the formula. Click the label on Column A to select it. In the Table Menu, select Add Column After, to make a blank column to the right of the full name column. Let's assume that your first row is a Header Row, so you won't have data or equations in the first row. In the second row of the new column, paste this expression: =IFERROR(LEFT(A, FIND (" ", A)-1), "") (Copied from here)
That cell that you pasted the expression into should now show the first name of the person in row 2. Now select that row 2 cell and Shift-Click the last cell in that column so that all the cells from row 2 down are selected. Next select Insert > Fill > Fill Down.
Now all your first names should be showing.
Let us know if you have any trouble with this.

If you don't have a means of restricting your query to only return 1 row based on data you would have to use the row number...
e.g.
select data, data2, .....

from table
where rn = 1
In this case you even don´t need the inline view:I know, but if an "order by" is included in the inline view then it's necessary as rownum is assigned before the ordering is done, hence it is always safer to do it this way. ;)

How to get first row from view iterator programatically?

Hi All,
I am using Jdeveloper 11g Release 2.
I want to fetch the first row of a view iterator in a bean. Can any one guide me through this use case.
Any help will be highly appreciated.
Thanks ... Best Regards
Bilal

Use the code snippet as below:
*// 1. Access the binding container*
DCBindingContainer bc = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
*// 2. Find a named iterator binding*
DCIteratorBinding iter = (DCIteratorBinding)bc.findIteratorBinding("<ITERATOR_NAME>");
*//3. Get the RowSetIterator Object*
RowSetIterator rsi = iter.getRowSetIterator();
*//4. Get the First Row*
Row firstRow = rsi.first();
Thanks,

First row from Service Order Object list not stored in OBJK table

Hi all,
Please be patience with my terminology .
Could you please explain me if we have SO created based on notification, and that notification already have Equipment number, why this equipment is not created in OBJK table? So always the first row (as in attachment) is not stored in OBJK, other rows(objects) are there.
I know the EQUNR is stored in AFIH, but it's useless for us because I'm creating HANA analytical view with following join logic (simplified):
AFIH.OBKNR=OBJK.OBKNR
OBJK.ILOAN=ILOA.ILOAN
ILOA.TPLNR=IFLOT.TPLNR
ILOA.ILOAN=EQUZ.ILOAN (where EQUZ.DATBI='99991231')
EQUZ.EQUNR=EQUI.EQUNR
The join logic might not be 100% correct.
Thank you for your help.

I am wanting to exactly match two ID numbers from two differing worksheets within one work book. Once matched I am wanting to retrieve a row value from the second worksheet into the first. Any help much appreciated.

I am wanting to exactly match two ID numbers from two worksheets within the one work book. ID numbers are non linear. Once exactly matched I wish to retrieve a corresponding row value from worksheet two and have it appear in worksheet one against the correct ID number. I have been looking at IF, VLOOKUP, and MATCH functions and suspect that what I want to do requires a combination of two or more. Any help will be greatly appreciated.

Vaughan,
Data A:D is all cells start at column A thru column D.
There is built-in help using the menu item "View > Show Function Browser" in the search field (top right) you can enter vlookup and you will see the detailed description.
From this we see:
VLOOKUP
(search-for, columns-range, return-column, close-match)
search-for: The value to find. search-value can contain any value type.
columns-range: A range of cells. range is a reference to a single range of cells, which may contain values of any type.
return-column: A number that specifies the relative column number of the cell from which to return the value. return-column is a number value. The leftmost column in the range is column 1.
close-match: An optional value that determines whether an exact match is required.
close match (TRUE, 1, or omitted): If there’s no exact match, select the column with the largest top-row value that is less than the search value. Wildcards can’t be used in search-for.
exact match (FALSE or 0): If there’s no exact match, return an error. Wildcards can be used in search-for.
So... the 2,0 means return the value form the same row as the lookup value but from the 2nd column of the range. 3, 0 means from the 3rd column. the ", 0" means exact match

Select first row from every set

id num dtl sdate udate

For each record having the same num, i want only one record picked, and that one should not have udate blank.
How can I do this using ROWNUM?

columns in order by. Here unique can't help (while row_number() will
also return one row (another question is it wnat you need or not):

Now the problem is that
if my xml file contain any tag whose value is not defined like
<root>
<firsttag>first</firsttag>
<Second></Second><Third>third</Third>
</root>
Now look if second tag doesnt contain anything ,then i want to add "null" to vector,but it throws null pointer exception because second tag is empty.
Vector<String> CSWFinfo = new Vector<String>();
          try {
               DocumentBuilderFactory factory = DocumentBuilderFactory
                         .newInstance();
               DocumentBuilder builder = factory.newDocumentBuilder();
               Document doc = builder.parse(new File(xml));
               Element root = doc.getDocumentElement();
               NodeList node = root.getChildNodes();
               for (int i = 0; i < node.getLength(); i++) {
                    Node currentNode = node.item(i);
                    if (isTextNode(currentNode))
                         continue;
                    CSWFinfo.addElement(currentNode.getNodeName());

Can any one know how to do it????
Edited by: chauhan2003 on 16 Jun, 2008 12:06 PM

Are you sure that all currentNode have a firstChild ????
If your node has no value, it has no child
So i 'd change code to like look something like:
if (currentNode.getFirstChild() != null) {
     CSWFinfo.addElement(currentNode.getFirstChild().getNodeValue());
} else {
     CSWFinfo.addElement("null");
}

My hard drive crashed on my apple computer recently. I have a new one, but it won't sync with apple tv1, and I want to retrieve my photos from teh appletv1. It appears in devices now, but won't let me go any further with it. Help

The hard drive crashed on my apple computer and I lost a lot of photos. I want to recover them from my apple tv1, but the computer won't seem to pair up with the apple tv. The Apple tv does appear in devices, but it won't let me go any further. The 'apply' button is a pale grey colour and you can't click on it. Help!!

there is no facility to recover your photos from the appletv.
the only way to link the appletv to your new "system" is to remove the existing itunes link and then link it to the new itunes - this will delete all content from the appletv though.
