RowSetIterator skipping the first row?

Hi,
I have an ADF Bindings methodIterator, defined in a page definition, as follows:
<executables>
    <methodIterator id="querySrtFaktRglDetFindBySrtFaktRglIter"
                    Binds="querySrtFaktRglDetFindBySrtFaktRgl.result"
                    DataControl="Services" RangeSize="-1"
                    BeanClass="company.entities.SrtFaktRglDet"/>
    
</executables>
<bindings>
    <methodAction id="querySrtFaktRglDetFindBySrtFaktRgl"
                  InstanceName="Services.dataProvider"
                  DataControl="Services" RequiresUpdateModel="true"
                  Action="invokeMethod"
                  MethodName="querySrtFaktRglDetFindBySrtFaktRgl"
                  IsViewObjectMethod="false"
                  ReturnName="Services.methodResults.querySrtFaktRglDetFindBySrtFaktRgl_Services_dataProvider_querySrtFaktRglDetFindBySrtFaktRgl_result">
      <NamedData NDName="cdeSrtFakt" NDType="java.lang.String"
                 NDValue="${bindings.cdeSrtFakt.inputValue}"/>
      <NamedData NDName="cdeSrtFaktRgl" NDType="java.lang.String"
                 NDValue="${bindings.cdeSrtFaktRgl.inputValue}"/>
    </methodAction>
    
</bindings>I want to use this in a bean that is on the pageFlowScope, as follows:
    public Map<String, SrtFaktRglDet> getSrtFaktRglDets() {
        // lazy initialization
        if (null == srtFaktRglDets || srtFaktRglDets.size() <= 0) {
            srtFaktRglDets = new HashMap<String, SrtFaktRglDet>();
            // getBindings returns a reference to the binding container
            DCBindingContainer bindings = getBindigns();
            DCIteratorBinding srtFaktRglDetIter = bindings.findIteratorBinding("querySrtFaktRglDetFindBySrtFaktRglIter");
            RowSetIterator iter = srtFaktRglDetIter.getRowSetIterator();
            while (null != iter && iter.hasNext()) {
                Row row = iter.next();
                SrtFaktRglDet srtFaktRglDet = (SrtFaktRglDet)((DCDataRow)row).getDataProvider();
                srtFaktRglDets.put(srtFaktRglDet.getCdeSrtFaktRglDet(), srtFaktRglDet);
        return srtFaktRglDets;
    }The resulting map is used in the page, with JSF EL. While testing, I noticed that the map always had one element less than could be expected, based on the database contents. It looks like the first call tho iter.next() does return the 2nd row, instead of the 1st. Is this a known problem with RowSetIterators?

Hi all,
I have similar case, createRowSetIterator() worked fine until I tunned my VO...
When I changed "*Access Mode*" from default Scrollable+ to Range Paging Incremental+ this error ocurred:
oracle.jbo.InvalidOperException: JBO-25083: Cannot create a secondary iterator on row set myVO because the access mode is "forward-only" or "range-paging"
I'm using JDeveloper/ADF 11.1.1.4.0.
In documentation I cannot find such restriction:
[http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974/bcadvvo.htm]
38.1.9 Working with Multiple Row Sets and Row Set Iterators
What can be done in this case?
I have very large dataset and GUI works on primary iterator.
Please advise.
regards,
Miroslaw

Lock the first row in an ordered table

Hi,
I have a table (TD_EVENTOS). I want to lock the row with te minimun value of a column (a timestamp called hora_evento) and some requirements of other columns. Then i build a cursor like this:
CURSOR c is select * from td_eventos where (...) order by hora_evento for update skip locked;
And then I make a fetch into this cursor and I get the row (locked) that I want. But i need the speedest way, and making that cursor it orders all rown in the table (when I only want the first row without lock) and when that table has 6000 or 7000 rows it wastes around 130 ms. My solution is to add to the WHERE a AND rownum < 50, and it only orders 50 rows (in 10 ms), but it orders 50 aleatory rows, and that`s not what I want.
Any solution faster?
Thanks!

Sorry that wasn't clear of me and could be misleading. I didn't mean Oracle would have to do a full table scan, another access path such as an appropriate index scan would do. I was trying to get across that to do any kind of order or min or max, all records have to be investigated. Since the fact that you don't know a row is locked until you try to lock it, you clearly can't filter on it (it's not a data attribute).
Apologies for any confusion my earlier post might have caused.
The suggestion about using a sorted hash cluster still stands though, they are designed for FIFO queues.
Which reminds me - SKIP LOCKED is in fact undocumented but everybody knows that Oracle use it internally for doing AQ. Since it's undocumented, you don't know how it works, when it will work, when it won't and of course Oracle can turn around and say "we don't support this".

How do I set only the first row of a DataGrid as the selected row?

I have a "Go" button on a search form that fetches data into an already data bound grid. After the data is fetched, I want to make the first row in the Datagrid the selected row, as if the user clicked on it. If the result set is empty, I don't want the code to crash. (I only want one row to be able to be selected at a time)
            protected function btnGo_clickHandler(event:MouseEvent):void
                getSBJsResult.token = baa_data_svc.getSBJs(cmbSrch.text);
                grdSBJs. // ????? What goes here to select the first row?

This should do it.

How can I get Numbers to return the first row in a group of VLOOKUP query results instead of last one?

I'm trying to query from one table (call it Table1) a batch of rows in another table (Table2) using VLOOKUP on a date specified in the first table (Table1). My problem is it's returning the last incident in Table2 of the requested date instead of the first incident. This really breaks the OFFSET scheme I'd like to use to collect the rest of the items for that date. Is there some way to compel VLOOKUP to return the first row of query results, not the last?
NOTE: I see I've asked this before, but forgot to go back and look at responses given. It's been a while and I've limped along until now with the way things were. I'm actually trying to delete this questions, so if you see it, ignore it. I suppose if someone can tell me real quick how to delete a stupid question, that might be helpful.

Report sum on the first row

Hi All,
i have an report with a few columns an i sumerized them by clicking on the sum checkbox. My report result into data with a nice sum row at the bottom of the report.
The question is, is it possible to get this summary line to the beginning of the report as the first row of the report ?
Regards,

Yes, but you got to do that yourself like in this example using analytic functions:

How do I create a 1d array that takes a single calculation and insert the result into the first row and then the next calculation the next time the loop passes that point and puts the results in thsecond row and so on until the loop is exited.

The attached file is work inprogress, with some dummy data sp that I can test it out without having to connect to equipment.
The second tab is the one that I am having the problem with. the output array from the replace element appears to be starting at the index position of 1 rather than 0 but that is ok it is still show that the new data is placed in incrementing element locations. However the main array that I am trying to build that is suppose to take each new calculation and place it in the next index(row) does not ap
pear to be working or at least I am not getting any indication on the inidcator.
Basically what I am attempting to do is is gather some pulses from adevice for a minute, place the results for a calculation, so that it displays then do the same again the next minute, but put these result in the next row and so on until the specifiied time has expired and the loop exits. I need to have all results displayed and keep building the array(display until, the end of the test)Eventually I will have to include a min max section that displays the min and max values calculated, but that should be easy with the min max function.Actually I thought this should have been easy but, I gues I can not see the forest through the trees. Can any one help to slear this up for me.

I didn't really have time to dig in and understand your program in depth,
but I have a few tips for you that might things a bit easier:
- You use local variables excessively which really complicates things. Try
not to use them and it will make your life easier.
- If you flowchart the design (very similar to a dataflow diagram, keep in
mind!) you want to gather data, calculate a value from that data, store the
calculation in an array, and loop while the time is in a certain range. So
theres really not much need for a sequence as long as you get rid of the
local variables (sequences also complicate things)
- You loop again if timepassed+1 is still less than some constant. Rather
than messing with locals it seems so much easier to use a shiftregister (if
absolutely necessary) or in this case base it upon the number of iterations
of the loop. In this case it looks like "time passed" is the same thing as
the number of loop iterations, but I didn't check closely. There's an i
terminal in your whileloop to read for the number of iterations.
- After having simplified your design by eliminating unnecessary sequence
and local variables, you should be able to draw out the labview diagram.
Don't try to use the "insert into array" vis since theres no need. Each
iteration of your loop calculates a number which goes into the next position
of the array right? Pass your result outside the loop, and enable indexing
on the terminal so Labview automatically generates the array for you. If
your calculation is a function of previous data, then use a shift register
to keep previous values around.
I wish you luck. Post again if you have any questions. Without a more
detailed understanding of your task at hand it's kind of hard to post actual
code suggestions for you.

Get only the first row for duplicate data

Hello,
I have the following situation...
I have a table called employees with column (re, name, function) where "re" is the primary key.
I have to import data inside this table using an xml file, the problem is that some employees can be repeated inside this xml, that means, I'll have repeated "re"'s, and this columns is primary key of my table.
To workaround, I've created a table called employees_tmp that has the same structed as employees, but without the constraint of primary key, on this way I can import the xml data inside the table employees_tmp.
What I need now is copy the data from employees_tmp to employess, but for the cases where "re" is repeated, I just want to copy the first row found.
Just an example:
EMPLOYEES_TMP
RE NAME FUNCTION
0987 GABRIEL ANALYST
0987 GABRIEL MANAGER
0978 RANIERI ANALYST
0875 RICHARD VICE-PRESIDENT
I want to copy the data to make employees looks like
EMPLOYEES
RE NAME FUNCTION
0987 GABRIEL ANALYST
0978 RANIERI ANALYST
0875 RICHARD VICE-PRESIDENT
How could I do this?
I really appreciate any help.
Thanks

Try,
SELECT re, NAME, FUNCTION
FROM (SELECT re,
               NAME,
               FUNCTION,
               ROW_NUMBER () OVER (PARTITION BY re ORDER BY NAME) rn
          FROM employees_tmp)
WHERE rn = 1G.

Getting the first row for each group

Hi Everyone,
I have a query which returns a number of rows, all of which are valid. What I need to do is to get the first row for each group and work with those records.
For example ...
client flight startairport destairport stops
A fl123 LGW BKK 2
A fl124 LHR BKK 5
B fl432 LGW XYZ 7
B fl432 MAN ABC 8
.... etc.
I would need to return one row for Client A and one row for Client B (etc.) but find that I can't use the MIN function because it would return the MIN value for each column (i.e. mix up the rows). I also can use the rownum=1 because this would only return one row rather than one row per group (i.e. per client).
I have been investigating and most postings seem to say that it needs a second query to look up the first row for each grouping. This is a solution which would not really be practical because my query is already quite complex and incorporating duplicate subqueries would just make the whole thing much to cumbersome.
So what I really new is a "MIN by group" or a "TOP by group" or a "ROWNUM=1 by group" function.
Can anyone help me with this? I'm sure that there must be a command to handle this.
Regards and any thanks,
Alan Searle

Something like this:
select *
from (
   select table1.*
   row_number() over (partition by col1, col2 order by col3, col4) rn
   from table1
where rn = 1In the "partition by" clause you place what you normally would "group by".
In the "order by" clause you define which will have row_number = 1.
Edit:
PS. The [url http://download.oracle.com/docs/cd/E11882_01/server.112/e17118/functions004.htm#i81407]docs have more examples on using analytical functions ;-)

Can I execute a report and skip the first screen in CJE0

Is there something I'm missing.

I've tried using the following code to run project reports without having to select the report name and exectue, but it is still leaving the user on the screen for CJE0 with the correct report name, but it's not skipping the screen and executing the report. Can you see what I'm doing wrong.
Thank-you for your help

How to highlight the first row of a table

When entering the form, how do I get the first row of the table to be highlighted when it has not been selected yet? There is already data in the table. Thanks.
Allyson

Any ideas on what would cause this NOT to work? I added this row right after the table is created and populated and it is still not highlighted when I enter the form. The snippet of code that does this is:
MyTableModel modelS = (MyTableModel)dataModel.get("S");
jTable1 = new JTable(modelS);
jTable1.setRowSelectionInterval(0,0);MyTableModel is this:
class MyTableModel extends DefaultTableModel {
public MyTableModel(Object[] columnNames, int numRows) {
    super(columnNames, numRows);
public boolean isCellEditable(int row, int column) {
    if (TableKey == 'S') {
      if (column == 6) {
        return false;
    if (TableKey == 'O') {
      if (column == 0 || column == 4 || column == 5) {
        return false;
    if (TableKey == 'P') {
      return false;
return true;
}Can anyone help? Thanks.

When the user click on the request number it should skip the first screen o

when the user click on the request number it should skip the first screen of REV track and show the rev track request number details. On click of u201CBacku201D button on this screen the output screen of the report should be displayed again.

Hello Rohit,
What you can do is, when the User Clicks on any particular Request, you use the At Line-Selection Event. In that event, you can set the User Name to default "SY-UNAME" or any other user Name for the specific Request.
Again, if you want to check the Owner of the Request, you can use the Table E070 where you can Input the Request Number and get the Owner of the Request. Set the same in the User Name Field and Skip First Screen (SE09 Transaction).
Hope it was helpful.
Thanks and Regards,

Infopath submit button only works for the first row in a repeating table‏

Hi, I have a InfoPath Email submit button issue I could not figure out. I have a master/detail repeating table in my form, and one of fields is "EmailAddress" which shows customer's email address. I created a submit button and put the "EmailAddress"
field to "TO" object. When I tested it, the submit button only would return the first row of emailaddress from the repeating table, but not the rest of it..
What I want is when I highlighted a customer, and click the submit button, the current customer's email address would show up in "TO" list. I did some research and saw some suggestions about using current() function. So I put current() in the front,
like this:
current()/dfs:dataFields/d:vw_HZLeadLists/@EmailAddress
Still not working..Just return the first record of emailaddress from master repeating table... Does anyone know what's going on here? Thanks a lot!

Hello,
Use double eval to get all rows values. See my reply for more information in below thread:
eval(eval(EmailAddress, 'concat(ToField, ";")'), "..")

Calling a transaction and skipping the first screen

Dear forumers,
In my report program, I will need to call a custom transaction with skipping the first screen.
And, this custom transaction is created from a query.
Currently, the codes look like below:-
        SET PARAMETER ID: 'BUK' FIELD w_output-bukrs,
                          'AN1' FIELD w_output-anln1.
        CALL TRANSACTION 'ZCUSTQ' AND SKIP FIRST SCREEN.
Everything works perfectly alright except for one thing: The first screen is not skipped. When the custom transaction is called, the first screen is still displayed to the user.
Additionally, I also found out that the "SKIP FIRST SCREEN" does not work because the screen's next screen number is the same. This means the screen 1000's next screen is 1000 as well.
(See notes in italics below)
Does anyone have any ideas on how to resolve this? Please help.
This addition suppresses the display of a screen of the initial dynpro of a called dialog transaction. The addition AND SKIP FIRST SCREEN suppresses the first screen under these prerequisites:
For the initial dynpro, in the Screen Painter the own dynpro number must not be specified as the next screen number.
All mandatory input fields of the initial dynpro must be filled completely and with the correct values by the SPA/GPA parameters
If these prerequisites are met, that screen of the dynpro is displayed that is specified in the Screen Painter as the next dynpro of the initial dynpro.

For Any Query , if you want to create the Transaction you need to use the Tcode START_REPORT
in general it will skip the first Transaction codes selection screen , Not your query reports selection screen.
I checked and verfied...
Steps to verify the issue..
1.Go to SE93 ,Now you will go for parametric transaction.
2. give the Transaction as START_REPORT, there you will have option Skip Initial Screen. You uncheck that.
3. Now give all information related to your query.
and see the effect
call TRANSACTION 'YYTCODE AND SKIP FIRST SCREEN.
This will always trying to skip the First transaction's selection/initial screen , Not your Query selection screen.
You also try to check and let me know.
