Range Paging rownum question
I am using JDeveloper 11.1.1.3.0 and I have a question about the range paging access mode and I went through some docs but couldn't get myself to answer all the questions I have.
1. In the VO's I set the Access Mode to Range Paging and set the Range Size to 25 but I only have (at this time) 19 rows. But in the logs, I notice:
"<OracleSQLBuilderImpl><bindRangePagingParams> [2540] setting rownum query between (0, 28)"
which doesn't make sense. Firstly, 0-28 is not a 25 row range and secondly, why is the SQL even accessing anything outside the range of 25 when there are only 19 rows for the VO?
2. Also, I have two buttons on the page (page fragment #1) which performs operations (add a new row, version an existing row) by having the user go to a different page fragment (page fragment #2). After the user submits the info and returns to the original page (page fragment #1), I see this message in a pop-up:
"Cannot navigate with unposted rows in a RangePaging RowSet"
which, although not an error, doesn't make sense because the info was saved in the DB.
Hope my questions make sense.
I don't have the url reference handy for the "official" word, but I recall that jdev overfetches 3 records in range paging mode.
It's not known that there are only 19 records until the first batch is fetched, which is why you see 0-28.
Just noticed the second question - no comment on that one, unfortunately ;)

ADF BC: range paging on dynamic view object
hi!
i have a dynamically generated sql query and i want to get the results one page at a time. for this to work i create at runtime a view object and try to use range paging:
String sql = "SELECT ...";
ViewObject vo = appModule.createViewObjectFromQueryStmt("tmpVO"+System.currentTimeMillis(), sql);
vo.setRangeSize(pageSize);
vo.setAccessMode(RowSet.RANGE_PAGING);
vo.scrollToRangePage(pageNo);
vo.getEstimatedRowCount();
Row[] rows = vo.getAllRowsInRange();
vo.remove();
but when i run this it was pretty slow. so i traced the database session and saw that the executed query was the sql string, not the range paging select (SELECT * FROM (SELECT /*+ FIRST_ROWS */ IQ.*, ROWNUM AS Z_R_N FROM (...).
i use range paging on other view objects that are not dynamically generated and it works fine. please tell me what can i do to get only the specified page from the data base.
thank you

here is the select i run:

PS: I am using JDev 10.1.3.36.73You have a couple of choices. You could create one view object with a bind variable parameter(s) and in the application module you have 10 instances of that VO with appropriate values set for the bind variable in each instance.
Or if you are using the LOV feature of a VO then you can set an attribute to point to one VO and then using a view cirteria applied to that specific LOV you can then "filter" the data that would appear in that LOV.
Does that help?

Named View Criteria and Range paging don't work together
Hi,
I am using a named view criteria for a view whose access mode is set to range paging.
When I use the named view criteria on my page to do a search I am getting the below error. If I don't use range paging as access mode for the view I don't get this error. Looks like when I use the search it doesn't pass the row numbers properly and they are not set in the query.
Is this a known issue or am I missing something?
Thanks

Muhammed SoyerHi Frank,
I didn't test it in 10g. It was something that I came across and thought that it might be a known issue..
The query is not something that I built manually. My entity is created from a table and my view is using the entity. I added a Named Criteria to the view and used Range Paging as access mode for the view.
The actual query is this
SELECT Persons.PRINCIPAL_NAME,
Persons.PERSON_ID,
Persons.TITLE,
Persons.FIRST_NAME,
Persons.LAST_NAME,
Persons.PHONE_NUMBER

Issue with ADF table range paging and sorting
Hello,
We have a requirement to support pagination in ADF tables. For this, we have made use of Range paging access mode in the view object level. The paging works perfectly fine with this. But we have another requirement of letting the user do a sort on the table (Yes!! The paginated table). The sort should be applied on all rows in the db and the control should return to the first row.
Applying sort as it is provided by the fwk, sorts the records in the obtained range only. So we have over ridden the Sort listener in Managed bean for this and are able to acheive the sorting of all rows through a AM method call. We are seeing a problem after this. If the sort action is applied to the key attribute then the previous and next range navigation works fine. If the same action is applied to non-key field, then some times (yea!! This is not consistent) the next set is not fetched.
Here is the code snippet that is called on Next navigation:
Map<String,Object> pfScope = AdfFacesContext.getCurrentInstance().getPageFlowScope();
Object objPageNumber = pfScope.get("pageNumber");
int pageNumber = 0;
if(null != objPageNumber)
pageNumber = new Integer(objPageNumber.toString()).intValue();
BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
JUCtrlRangeBinding view = (JUCtrlRangeBinding)bindings.getControlBinding("GeDmRequestVO");
int iRange = getTable().getAutoHeightRows();
int currentPage = view.getIteratorBinding().getNavigatableRowIterator().getRangeStart()/(iRange + 1);
System.out.println("Before " + view.getIteratorBinding().getNavigatableRowIterator().getRangeStart());
System.out.println("Current : " + currentPage);
System.out.println("Page Number : " + pageNumber);
System.out.println("Range : " + iRange);
System.out.println("Value : " + iRange*(currentPage + pageNumber));
view.getIteratorBinding().getNavigatableRowIterator().scrollRange(iRange*pageNumber);
System.out.println("After " + view.getIteratorBinding().getNavigatableRowIterator().getRangeStart());
Although, the new values are not refreshed in the table, the SOPs for before and after print the proper range sizes. And as I mentioned above, the above code works perfectly fine if there is no sort applied or when key attribute is sorted.
Would appreciate your help on this regard with navigation after non-key attribute sort.
Thanks,
Chitra.Hi Chitra,
Can you specify some links to implement RangePaging.....We need to implement pagination.If possible can you share the code or specify the steps how you achieved it.

Error in ADF View Object Range Paging ?
Hi all,
I've used the range paging technique (similar to the paging action example posted by Steve Muench). It works for most cases. However, I found a strange behaviour with getEstimatedRangePageCount call as described below :
e.g.
VOs on Table A(key1) -> Table B (key1, key2, fld1) with records of table B:
k1, 1, 'ABC'
k2, 1, 'BCD'
k2, 2, 'CDE'
k2, 3, 'EFG'
k3, 1, 'DBCD'
k3, 2, 'DCDE'
k3, 3, 'EEFG'
k3, 4, 'EFFG'
RangeSize of table B = 1
There are 2 screens : one is master/detail screen and another search screen to pass key1 to the master/detail screen
The JSP screen is master(table A) with navigation buttons on detail (table B)
The sequence of actions are as follows :
1. search screen with key1=k2
2. display m/d screen with key1 = k2 (getEstimatedRangePageCount return 3)
3. go back to search screen and set key1=k3
4. display m/d screen wtih key1 = k3 (getEstimatedRangePageCount return 4)
5. go back to search screen and set key1=k1
6. display m/d screen wtih key1 = k1 (getEstimatedRangePageCount return 1)
7. go back to search screen and set key1=k3
8. display m/d screen wtih key1 = k3 (getEstimatedRangePageCount return 1 instead of 4)
9. go back to search screen and set key1=k3
10. display m/d screen wtih key1 = k3 (getEstimatedRangePageCount return 4)
Does anyone know what happen or how can it be solved ?
Thanks,
Nelson.Repost.
Can anyone help ?

Problems using writeXML on Range Paging ViewObject
We have a ViewObject configured to work with Range Page feature (it has up to 150 thousand rows), it works very nicely, fast and fine.
But the problem appears when we try to use the writeXML functionality on this Range Paging ViewObject, and exception is thrown, seems that writeXML calls any other rowset method than next().
Any suggestion about how to solve this problem? (without disabling range paging feature on the ViewObject).
Thanks in advanced.

anyone tried the new Range Paging Feature in 9.0.5 preview version? it works well?
i try to fecth rows in sets of 10 and when i need more i make a scrollRange(),setRangeStart(),...
in SCROLLABLE mode this works well but in RANGE_PAGING mode this only returns 2 pages, i can't go to the third page (the range size is 10 and i have 20000 rows in database).
how can i count the rows? now this.getRowSet().getRowCount(); don�t work because rows are not in the RowSet
any help?
thanksscrollRange (+/- rowCount) should scroll the 'rowCount' number of rows. You may also use scrollToRangePage method and pass in index of which page to jump to.
getRowCOunt() will return the count of rows in the cache and in case of range paging that should be range size + some buffered rows. You may use getEStimatedRowCOunt() to get the valid row count. -
Duplicate iterators on range paging VOs
Hi all,
For performance reasons we want to use range paging VOs for our application. We have logic where we need to create duplicate iterators on VOs to compute some values. But when access mode of VOs is not scrollable we are getting exceptions that duplicate iterators and rowsets cannot be created. Any suggestions on how to overcome this problem, both in managed beans and in BC code ?
-RamkuThanks Dimitris for your reply.
Yes. createRowSetIterator("") throws JBO-25083: Cannot create a secondary iterator on row set {0} because the access mode is forward-only or range-paging.
Is there a way to change access mode of VO programatically or some trick to work around this problem ?
-Ramku -
We try to use the range paging feature of 9.0.5.1 with a JTable. The API doc isn't very helpful on this subject.
Is there any example code on using range paging with JClient ?
We used setRangeSize(), scrollRange() on the view object. With acces mode SCROLLABLE we face following effect: JTable seems to be filled with all rows of the query result, but only the data of the rows in the range are visible. All other rows are existing but are empty. This is a strange behavior and not very useful.
With access mode RANGE_PAGING we got following exception on executeQuery(), but the query is correct and runs with access mode SCROLLABLE:
class oracle.jbo.SQLStmtException: JBO-27122: SQL error during statement preparation.

Hi all,
I am trying to figure out a way of paging through a large set of rows in a view object without loading all the rows into the cache. In BC4J 9.0.4 there seems to be a new API (as described in http://radio.weblogs.com/0118231/stories/2003/01/26/quickOverviewOfNewBc4j904RangePagingFeature.html). However, we are using 9.0.3. Is there any way to have this functionality without implementing it manually (e.g. by setting ROWNUM in the query)?
Thanks for any hint!
Markus.Hi,
I have a UIX page which shows 10 members per page. As we are getting "Out of memory" error for one of our clients because of large data, I have enabled RANGE_PAGING feature for that page, followed all the procedures like:
1. All Rows in Batches of : 13
2. Checked Passivate State
3. In the Application module, overridden the method - "PrepareSession"
with the following code:
ViewObjectImpl vo = getMemInfoViewMemSearchPage1();
vo.setAccessMode(RowSet.RANGE_PAGING);
When I first go to the page, it is showing 10 members out of the entrie count with 1-10 of 30000. But when I click "Next", it is just showing 3.
By this I believe it is not executing the query for the second set and if I explicitly call the execute Query on View Object, I believe paging may not work.
I would really appreciate anyone's help in this regard.
Thanks

Order by range? mysql Question
hi all ! I need to know if this is possible in sql.
I have a table with a Column called Hours, what I want to do its to count objects that are in a certain Hour range.
Something like:
Select Count(citas.Protocolo),citas.Hora,citas.Protocolo FROM citas WHERE citas.Fecha="2006-09-27"
AND Horaentrada!="00:00:00" GROUP BY citas.Hora,citas.Protocolo Order by Citas.HoraWHat I try is to get the count between 8:00 and 8:59 and then 9:00 and 9:59 ,etc ,etc but automaticly since I cant do a between.
Now what I get is
8:00 Count =1
8:10 Count= 2
8:20 Count=1
WHat I try to achieve
Count=4 between 8:00 and 8:59No, it will not give an error. You need not specify the order by with both the queries just write that at the end of last querfy and that will work.
select empno from emp
union all
select empno from emp
order by 1 desc
EMPNO

XSQL Paging Example Questions - XMLBOOK
Hi all,
I run example NewsCategorySimple.xsql?p=2&id=1 from XMLBOOK (S.Muench pag. 650), but it doesn't show stateless paging. shows data, but not: Page 1 of 4 Next - Total 19.
I run over WNT4/Sp5, Ora816/R2, WEBDB/IAS, XSQL Utility (Examples is good), I don't have jdev 3.1 (is necesary?), my evironment variable CLASSPATH is add c:\xmlbook\samples\ch17\classes;....
Examples http://localhost/orxmlapp/samples/ch17/store.html is good
I think what configure Jserv (jserv.conf or jserv.properties) is the problem. can anybody help me
Thanks..thanks, Steve
now is ok, but i have an other problem, in the URL: http://ias/orxmlapp/Examples/ch17/
I see the main page (index.html) and the message:
"No stocks selected" and "You have not selected any news categories... Preferences for roy-ayala". (XMLBOOK pag. 684, Fig. 17-23)
I added: wrapper.classpath=C:\xmlbook\samples\ch17\classes
wrapper.classpath=C:\xmlbook\samples\ch06\classes
in jserv.properties.
and run all script in ch06 / ch17
what do you think

So I have a SQL query in which I look at the ROWNUM and then perform formatting based on the row number. For example all rows under 15 show up with a highlighted column of blue, 16-30 show up red, etc. I want all of the rows from the blue group together and so on. I had an order by clause on the query of rownum but this wasn't working as expected as the returned results were always different for each user. I then tried to change the order by to sort by the primary key but then the highlighted rows aren't all together. Isn't the ROWNUM supposed to be read after the where clause? Here is my query below any ideas on how to get it functioning correctly.

order by ROWNUMThank you for your help...I will look at rewriting the case using the width once I get the return sequence correct. I have changed my query to below and it still doesn't seem to work...I must be doing something wrong! If I put an order by my_rownum then all the blocks are together but not in sequential order. If I set an order by clause of the id then the ids are sequential but the blocks are incorrect. I thought I had understood the previous replies and I read through the links but not sure what I am missing.

UCCX Trigger Range and Reporting Question
Hello Everyone:
I are using a wildcard trigger so that instead of having 30 triggers to one application, I can just leverage that one trigger. That part is working great, however the issue is that when looking at reports we are only seeing the Wildcard Trigger and not the full extension. Specifically we are looking at the Abandoned Call Detail Activity Report. We want to pull out calls for each trigger as each trigger represents a different location. Is there a way to expose the "Original Called Number" field to get this data? That way the called number will be the range it hit, with the Original Called Number field being the specific location. I'm hoping there is a way to get this data, outside of developing a custom report. Any help would be appreciated - Thanks!
SeanSean,
You will need to create a custom report for this.
