Using sequence in view

hi gurus
SQL> create view v1 as select s1.nextval from dual;
create view v1 as select s1.nextval from dual
*+
ERROR at line 1:
ORA-02287: sequence number not allowed here
Are there only workaround?
Thank you!

There are some restrictions on using sequences you will want to know about

How to Use Sequence in Oracle Views

Hi ,
I have created a view which gives the information about the access rights which a Resource has got. for ex -
Res1 - GYM access - member
Res1 - Swimingpool Access - member
I need to identify a Primary Key for this data set. So i thought that i'll use a Sequence to generate an extra column in this view.
But when i'm using the Sequence i'm getting the following error - "ORA-02287".

you can use sequence within view it doesnot returned error;
create sequence t1_seq MAXVALUE 150
START WITH 39 INCREMENT BY 1;
SQL> insert into t1_view values(t1_seq.nextval,'dd');
1 row created.
SQL> commit;
Commit complete.
SQL> select * from t1;
ID NA
10 aa
20 bb
30 cc
40 dd
4 rows selected.
SQL> insert into t1_view values(t1_seq.nextval,'ee');
1 row created.
SQL> commit;
Commit complete.
SQL> select * from t1;
ID NA
10 aa
20 bb

5 rows selected.

How do I obtain the next number for a Primary Key using an ADF View Object?

I have two separate View Objects (A & B) for the same Entity Object. View Object A does a SELECT on all of the fields in the table. This View Object is where I execute my adds and updates. View Object B is only used to retrieve the next number for the primary key. This is done so that when I add a row to the database, I always get the max number of the primary key and add one to it. I accomplished this by setting the SQL mode to Expert and using the SQL: "SELECT MAX(NBR) AS MAX_NUMBER FROM TABLE_1". This may be overkill having a seperate View Object for this, but so far this is the only way I have found to obtain the next number. However, I have discovered that this way does not always work.
The problem I'm running into is when I try to add multiple records to View Object A without committing the transaction between each add. Because View Object B is disconnected from View Object A, the MAX_NUMBER of View Object B comes back with the same number for each add I do on View Object A. So I know I must retrieve the MAX_NUMBER from View Object A.
I've tried using the following code in my Table1ViewImpl class:
this.setQuery("SELECT MAX(Table1.NBR) AS MAX_NUMBER FROM TABLE_1 Table1");
this.executeQuery();
The view object now has what I want, but I have yet to figure a way to extract the MAX_NUMBER out of the View Object. I've also looked into using the method addDynamicAttribute() but I can't figure out any way to set the attribute with the MAX_NUMBER.
I can't be the only one trying to retrieve the next number from a database table using ADF. Can anyone help me with this? FYI - I'm using JDev 10.1.3 EA.

You missing the point.
On a multi-user db knowing the next highest number doesn't guarantee the number will be available when it comes time to commit the record. You can prove this to yourself by opening two instances of your app and do whatever you do to add a new record to your VO. Both will assume the same number, and when you commit an error will be generated
You must use sequences to avoid the possibility of duplicate keys. If you are trying to avoid gaps in your numbering then you need to convince yourself why this is necessary.

Sequencing of views in MM01

Hi Gurus
Customer Requirement is to maintain the sequencing of views in MM01.
say sequence is KTEN...
If we try to maintain view N after K then there should be error..
any idea welcome..
Thanks in advance

Hi
It is always better to maintain the sequence like this (same as MM01 sequence)

MAX(SummaryNum) +1 bad idea, but how to use sequence part composite column

Hi,
My relational mode is as follows
Policy (policynum PK) has 1:M with Summary (policynum FK, SummaryNum part of PK, other columns part of PK)
Basically for each policy users can enter notes with SummaryNum 1, 2, 3, 4.... These numbers are shown to the user for tracking purpose. I need to make sure summary notes for EACH policy start with 1 (cannot really use sequence in the table in the strictest sense) and are incremented by 1. The current Oracle form basically creates the next highest possible value of SummaryNum by adding one to the currently available highest value. In brief, it is like a sequence number for summaries of a particular policy in the summary table.
PRE-INSERT
SELECT MAX(SummaryNum ) + 1
FROM Summary
I am trying to replicate this in ADF BC (using 11g) and know that not using sequencing and adding one to get the next number is a very bad idea due to concurrency challenges (transactional ACID properties). The reasons are as follows.
•     Using MAX(policy_memo_seq_num) + 1 is not scalable,
•     It will lead to duplicates in a multi-user environment, whether ADF BC, Oracle Forms, or any other technology
I also know how to use create a sequence in db, a related trigger, and then set the attribute in EO properties as DBSequence. My challenge is that since SummaryNum is not a primary key, and instead is part of a composite key in my case, how do I make sure that summary notes for EACH policy start with 1 in the Summary Table.
I appears that i cannot really use sequence in the table in the strictest sense as this will mean that for policies the summaryNum will start from the next available sequence number, but what i really want is to have it start by one for all policies.*
I would appreciate any help.
Thanks,

Not sure if there is a better way, but here is one way. Let's say your table was like this:
    SQL> desc versioned_item
     Name         Null?    Type
     ID           NOT NULL NUMBER
     VERSION      NOT NULL NUMBER
     DESCRIPTION           VARCHAR2(20)and lets say your data looked like this:
    SQL> select * from versioned_item order by id, version
            ID    VERSION DESCRIPTION
          1001          1 Item 1001
          1001          2 Item 1001
          1001          3 Item 1001
          1002          1 Item 1002
          1002          2 Item 1002
          1003          1 Item 1003To select only the rows for the max-version-id, you could do this:
    select id, version,description
    from versioned_item
    where (id,version) in (select id,max(version) from versioned_item group by id)
    order by id
            ID    VERSION DESCRIPTION
          1001          3 Item 1001
          1002          2 Item 1002
          1003          1 Item 1003To capture this as a view object, you'd only just need to paste in the WHERE clause above into the Where clause box of the view object. No need to use expert-mode since you're not changing the select list or from clause.

Since installing LTR 5.4, which I've now upgraded to 5.6, I've encountered repeated slowness and malfunctions in operations, especially when using the Compare View function and the Tab key to open and close the right and left side panels. Such problems never arose during two years of using LTR-4 and nothing else has changed on my computer. I have a pretty simple system with only a few plug-ins, which are usually not in operation. I have 12GB of RAM in my Windows 7 PC. I could illustrate these problems with screen shots if you would tell me how to submit screen shots. Otherwise I will try to describe the problems in words.
The problem is clearly cumulative, growing worse as usage time passes. Compare View feature gradually slows down and eventually seems to choke as my work session proceeds. If I Exit LTR and re-enter and start all over, things will work normally for maybe 30 minutes, but then the Compare View feature begins to become very slow to respond. In a recent example with my screen full of thumbnails in Library mode I highlighted two images to compare. LTR started to open the Compare View screen by first having the top row of thumbnails disappear to be replaced by the "SELECT" and "CANDIDATE" words in their spaces (but no images), but Compare View never succeeded in gaining control of the screen. After some seconds the top row of thumbnails reasserted its position and the Compare View windows disappeared. But LTR kept trying to bring them back. Again the top row of thumbnails would go away, Select and candidate would reappear, try again, and give up. This went on for at least 2-3 minutes before I tried to choose File and Exit, but even that did not initially want to respond. It doesn't like to accept other commands when it's trying to open Compare View. Finally it allowed me to exit.
To experiment I created a new catalog of 1100 images. After 30-40 minutes, the Compare View function began to operate very slowly. With left and right side panels visible and two thumbnails highlighted, hitting Compare View can take half a minute before the two mid-size images open in their respective SELECT and CANDIDATE windows. When the side panels are open and two images are in the Select/Candidate spaces, hitting the Tab button to close the side panels produces a very delayed response--25-30 seconds to close them, a few more seconds to enlarge the two images to full size. To reverse the process (i.e., to recall the two side panels), hitting Tab would make the two sides of the screen go black for up to a minute, with no words visible. Eventually the info fields in the panels would open up.
I also created a new user account and imported a folder of 160 images. After half an hour Compare View began mis-placing data. (I have a screen shot to show this.) CANDIDATE appears on the left side of SELECT, whereas it should be on the right. The accompanying camera exposure data appears almost entirely to the left of the mid-screen dividing line. Although the Candidate and Select headings were transposed, the image exposure data was not, but the data for the image on the right was almost entirely to the left of the line dividing the screen in two.
Gurus in The Lightroom Forum have examined Task Manager data showing Processes running and Performance indicators and they see nothing wrong. I could also send screen shots of this data.
At this point, the only way I can process my images is to work 30-40 minutes and then shut down everything, exit, and re-start LTR. This is not normal. I hope you can find the cause, and then the solution. If you would like to see my screen shots, tell me how to submit them.

Re: [SunONE-JATO] How to use a tiled view without a model

John,
Check out the docs for DefaultModel. There is an appendRow() method.
So get your tiledview's primary model (the tiledview's primary model
should be set to use an instance of DefaultModel), model.appendRow(),
then model.setValue("fieldname", value) for each value.
Rinse, repeat as needed.

Re: [SunONE-JATO] Re: How to use a tiled view without a model

I'm not sure what is different for you now. You still parse the string
and put it into a data structure. Before the data structure was a
vector, in JATO its just a model with a "hidden" data structure (a hash
map).
MVC only really comes into play when you talk about where your write
this code, and where the data structure is being stored. So really, JATO
takes care of half of the MVC'ness of it all (where the data is store).
You just decide where to be the code to populate the model.
Make sense?
Is there something different required of you in JATO in this scenario
that I am not grasping?

Hoskins, John D. wrote:
Thanks for the feedback.
The problem I was solving involved a single string, which contained
delimited subsets of information.
The string looked like
this:"time|analyst|description|time|analyst|description|..."
In ND, I parsed it apart into it's components (time vector, analyst vector,
description vector), populated the repeated.
With JATO, how would I make a model for something that doesn't have a
database component like this?
I'm pretty new to this MVC thing, so bear with me.

Subject: Re: [SunONE-JATO] Re: How to use a tiled view without a model
I guess the only thing "weird" (for lack of a better term) about what
you are doing is that your are populating the model on the "display
cycle". Typically, the cycle goes like this:
Request -> populate model -> update data store -> retrieve data to
populate model -> display data
some of the above steps are optional but hopefully you get the point I
am making.
So what you are doing is:
Request -> populate model/display data
If it works for you, then it's not necessarilly wrong. But I would
probably have my model populated before I forwarded to the target
(displaying view bean) or at a minimum, in the begin display event of
the view bean or the tiled view, but not during the iteration of the
tiled view.

I am trying to open a website that is using Microsoft content viewer, and the page does not show. Any ideas on how to view this site using firefox. It works on IE.

I am participating in an online class whose website uses Microsoft Content Viewer to view the class content. The browser opens a new page, but nothing is there. At the top of the tab it says Microsoft Content Viewer, and nothing else. Can anyone tell me how to view my course using Firefox? I would prefer not to use IE, but it works there.

When originally creating the pdf, you would need to choose another pdf conversion setting. In Word if you use the pdf menu, change your settings there: Adobe PDF > Change Conversion Settings. I would use High Quality Print instead. If you use the File > Print method, click the Properties button next to the Adobe PDF printer selection.
For your already created form, you can change the file so your users will not encounter issues. In Acrobat 9, which hopefully is similar in process to 8: Advanced > Preflight > Profile tab > PDF/A compliance > Remove PDF/A information.(You'll have to unsecure your form first).
You can read about PDF/A files in the Help.

Problem on using Crystal Report Viewer on windows application ("specified type is not valid ")

Hi
I am having problem on using Crystal Report Viewer on one of my windows application.
I am not sure how to put the Crystal Report Viewer 11 Control onto the tool box.
I could found a Crystal Report Viewer control on my computer, but it is version 8.5.
I have also found another one which is Called Crytal ActiveX Report Viewer, i don't think it is the one I can use. As when I try to load a dummy report on to the Crytal ActiveX Report Viewer, It return an error. "specified type is not valid"
Please see the Code sample below.
private sub loadReport()
     Dim r as New ReportDocument
     'v is the name of the Crystal ActiveX Report Viewer Control
     r.Load("C:\Report1.rtp")
     v.ReportSource(r) <---It throw error on this line.
End Sub
Could you give me some advice about what have I done wrong, How to check if I have set up the Crystal Report Component correctly in my Visual Studio 2005 Standard edition.
Thanks in advances.
Many thanks
Chi

VS 2005 Standard and Express editions do not come with Crystal Reports; only the Professional and higher editions will have CR bundled. However, I believe you can purchase CR XI R2 Developer and it will give you the components you need to create a VS .NET 2005 application using the Standard edition.

With this code , report gets displayed in the portlet but none of the actions on thre report like next page click , search button , opening subreport , clicking on drill-downs are working . The error in the explorer console is as shown below
Error: CrystalViewerCrystalEvent is not defined
javascript:CrystalViewerCrystalEvent('CrystalViewer',%20'tb=next')
PageSource of the web page shows the CrystalViewerCrystalEvent javascript function defined but for somereason its not recognized by the portlet. Has anyone worked on displaying crystalreports in a portlet ?

Paging issues using a dynamic view object...

I am working on an application that uses JAG to generate JSP pages, i had the requirement to use dynamic view objects where the view object query is generated at runtime. The rest of the application is more or less the same... I used the defult functionality provided by TableScrollButtons.jsp file for paging. Now the problem im facing is that while the '>' and '<' buttons are working fine, i cant seem to navigate to the pages using the drop down...
With the default handler, whenever i select the range the range displayed remains the same ie 1-10, 10 being the rangesize, but the rows are refreshed with values from the next page. Also, if the next page is the last and is incomplete, then the rows are pushed in from the bottom, so that the last page is always full...I tried the tuning panel in the view object edit dialogue and all settings are fine (i think)...could anyone please tell me what i am doing wrong??

could it be because i am using a dynamic view object with dynamic bindings? i am using the preparemodel() method in the action as follows...
protected void prepareModel(DataActionContext ctx) throws Exception {
inferRangeBindingIfUnset(ctx);
ctx.getBindingContainer().setEnableTokenValidation(false);
String sql = ctx.getHttpServletRequest().getParameter("sql");
String cost=ctx.getHttpServletRequest().getParameter("CostCostCent");
String event=ctx.getHttpServletRequest().getParameter("event");
if (sql != null && event == null) {
setupDynamicQueryAndDynamicBindings(ctx,sql.substring(1),cost);
if (retrieveOnlyCurrentPageFromDatabase()) {
ViewObject vo = getIterForPaging(ctx).getViewObject();
if (vo.getAccessMode() != ViewObject.RANGE_PAGING) {
vo.setAccessMode(ViewObject.RANGE_PAGING);
// if(event==null)
super.prepareModel(ctx);
ctx.getBindingContainer().setEnableTokenValidation(true);
if (ctx.getEvents() == null || ctx.getEvents().size() ==0) {
setPage(ctx,1);
setLastPage(ctx,getIterForPaging(ctx).getRowSetIterator().getEstimatedRangePageCount());
else if(event.equals("setRangeStart")) {
setPageFromRequest(ctx);
}

Error when trying to use the Log Viewer

Hello experts, today I wanted to examine some logs using the Log Viewer on Visual Administrator. However, when clicking on this service, the Visual Administrator would freeze for a long while and after that, an error message was displayed. I do not remember the exact message, but it was something like "A fatal error occurred. For more information, click on the Details button". After clicking on that button, the following error was displayed:

The lines I marked in bold are the ones that caught my attention. What is this error and how can I fix it?

Hello, thanks for your answers. I checked the JVM Heap size, we are using a 64 bit HW, and it was already set to 2048M, as well as both parameters Xms and Xmx. I also checked our virtual memory and directory space, the virtual memory looks fine, and the <SID> directory uses 5 GB of space.
If you wish, I can write the configuration found on the Config Tool, where you set the JVM Heap size and other parameters.
