Duplicate primary key values

Hi,
I have a EO based VO... say EOVO1 and non eo based VO say VO1.
User may update the fields which is based on VO1. Now i am trying to copy/update the value in the EOVO1 so that data will be saved on commit.
the data is something like this
Name Employee Item Serial Number ClaimReviewd
Here claim Reviewed is a checkbox which is based in VO1. Now when the user changes the value i need to update or create the record in the EOVO1.
The issue is, say user checks the claimreviewd check box, so i create a new row and update my EOVO1. Now again before commiting the user unchecks it.. Now my code is creating another row. But i need to check the middle tier to know whether this particular row has already been proceessed and i need to just update it instead of creating. Please let me know the approach.
Thanks,
Viswanath

Hi,
Refer the following pseudo code, this is wriiten in AMImpl:
public void deleteEmployee(String Id)
// First, we need to find the selected id in our VO.
int empToFind = Integer.parseInt(Id);
OAViewObject vo = (OAViewObject)getXXVO1();
XXVORowImpl row = null;
int fetchedRowCount = vo.getFetchedRowCount();
RowSetIterator createIter = vo.createRowSetIterator("createIter");
if (fetchedRowCount > 0)
createIter.setRangeStart(0);
createIter.setRangeSize(fetchedRowCount);
for (int i = 0; i < fetchedRowCount; i++)
row = (XXVORowImpl )deleteIter.getRowAtRangeIndex(i);
Number primaryKey = row.getId();
if (primaryKey.compareTo(empToFind) != 0)
getOADBTransaction().commit();
break; // only one possible selected row in this case
createIter .closeRowSetIterator();
Thanks,

Checking for duplicate primary keys on row inserts

Checking for duplicate primary keys on row inserts
I have a situation where I will be making bulk table inserts knowing that the primary key value will in some cases already exist. In this is the case I simply want to ignore the duplicate inserts.
Should I be performing a sub-query on the table and using a statement like:
where not exist in
Or is there a cleaner way of discarding or checking for duplicates on insert.
My concerns were mainly one of performance, as my routine will be inserting a few thousand rows in its operation.

The MERGE commnad is a good option when a large percentage of the data will exist in the target because it is much more efficient to attempt to update then insert when the update affects zero rows than capture an error and convert it to an update.
However, since in this case it would appear that only a few rows will alreadys exist and we want to ignore the duplicates when they exist then
begin
insert
exception
when dup_value_in_index then null;
end
would be the way to code this one. The bulk insert version has in 9.2 the ability to store the errors so that they can all be handled at once which means the rest of the array insert can work.

MAP 9.1 - Inventory is scanned but failed during Assessment, Duplicate Primary Key

Hi MAP team, saw the similar thread but didn't want to hijack it if it's a different root cause.
We have a client using MAP for data collection that is having failures with generating the assessment. In the MAPToolkitLog, we get this:
“Microsoft.AssessmentPlatform.MapException: Caught SqlException running the stored procedure [WinClient_Assessment].[LicensingAssessmentProc]. ---> System.Data.SqlClient.SqlException: Violation of PRIMARY KEY constraint 'LicensingAssessment_pk'. Cannot
insert duplicate key in object 'WinClient_Assessment.LicensingAssessment'. The duplicate key value is (4d74950a-3c31-4b7e-9464-12fd8ae03942).”
Tracing it down it looks like there are two entries for a DeviceNumber under Win_Inventory.SoftwareLicensingProducts, with these two descriptions: “Windows Operating System - Windows(R) 7, RETAIL channel”, and “Windows Operating System - Windows(R) 7, OEM_SLP
channel”. So two lines are trying to get created for an OEM and a RETAIL line in the LicensingAssessmentProc, causing a duplicate PRIMARY KEY and hence the issue with the assessment. Is this an existing bug and if so is there a quick way to resolve it so we
can conduct the assessments? The issue is that we cannot run additional scans to improve coverage as it wants us to refresh the assessment before letting us run another scan.
Thank you,
Nick

Following up on this, digging into the data it looks like "Windows(R) 7, OCUR add-on for Ultimate,HomePremium,Enterprise,Professional,ServerHomePremium,Embedded" is getting flagged as an OS and being included in the Win_Inventory.SoftwareLicensingProducts,
conflicting with the actual OS line. When I deleted those rows the duplicate primary key issue was resolved and we were able to process assessments. Not sure if we can run additional scans on that database, will check soon.
This is a pretty inconvenient way to get around this bug however, can this be addressed without having to delete SQL rows, or is this an edge case that needs to be caught in the filtering in the next release?

How can we export the Primary key values (along with other data) from an Advantage database?

One of our customers is moving from our application (which uses Advantage Database Server) to another application (which uses other database technology). They have asked us to help export their data, so that they can migrate it to another database system. So far, we have used the Advantage Data Architect (ARC32) "Export Table Structures as Code" functionality to generate SQL. We used the "Include existing data" option. The SQL contains the necessary code to recreate the tables and indexes. The customer's IT staff will alter the SQL statements as necessary for their new system.
However, there is an issue with the Primary Keys in these table. The resulting INSERT statements use AutoInc as the type for the Primary Key in each Table. These INSERT statements contains "DEFAULT" for the value of each of these AutoInc fields. The customer would like to output an integer value for each of these Primary Key values in order to maintain referential integrity in their new system.
So far, I have not found any feature of ARC32 that allows us to export the Primary Key values. We had been using an older version of ARC32, since our application does not use the latest version of ADS. I did download the latest version of ARC32 (11.10), but it does not appear to include any new functionality that would facilitate doing this sort of export.
Can somebody tell me if there is such a feature in ARC32?
Or, is there is another Advantage tool to facilitate what we are trying to accomplish?
If there are no Advantage tools to provide such functionality, what else would you suggest?

George,
It sounds like the approach you are using is the correct one. This seems to be the cleanest solution to me especially since the customer is able to modify the generated SQL statements for their new system.
In order to preserve the AutoInc values I would recommend altering the table and changing the field datatype from AutoInc to Integer. Then export the table as code which will export the actual values. After the tables have been created on the new system they can change the field datatype back to an AutoInc type if necessary.

Display the second report as modalform and filter with primary key value of first report when you click on first report column link

Hi All,
I have two reports.
1. order report
2. order detail report
when you click on the order report column it display the order detail report as a modal form.
i was done below steps.
1. In page header i was written the below code
<link rel="stylesheet" href = "http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/themes/
redmond/jquery-ui.css" type="text/css" />
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js"> </script>

<script type="text/javascript">
$( function() {
$('#ModalForm1').dialog(
autoOpen : false ,
width :470,
height: 500,
resize :false,
function openForm1()
$('#ModalForm1').dialog('open');
function closeForm()
$('#ModalForm1 input[type="text"]').val('');
$('#ModalForm1').dialog('close');
</script>
2. order report.
3. order detail report
select * from order_details where order_id = p_order_id;
region header
<div id="ModalForm1" title="Ordered Items" style="display:none">
<p class="msg"></p>
footer
</div>
4. created the hidden item in order detail report.
5. in order report column attributes i was given link like below.
javascript:$s('p_order_id','#order_id#');openForm1();
when i click on the order report column link it passing the row primary key value to hiddent and open the report as modal form. however it is not filter the report with hidden item. it showing the no data found.
problem is hidden item value is not submitting. once we submit that value it showing the 2nd report with filter data.
can any help me to achieve above requirement.
apex: 4.2
oracle 11g
Regards,
Vijay.

Vijay,
Issue 1: Your usage of $s() JavaScript API seems to be wrong. For the first parameter, you need to use the name of the hidden page item and not p_order_id.
javascript:$s('P1_ORDER_ID','#ORDER_ID#');openForm1();
Issue 2: Seems like you are not setting the hidden page item's value in session state. Assuming your hidden page item is called P1_ORDER_ID, Under "Region Definition" tab of your "Order Detail Report" under "Source" tab, for page items to submit, enter the name of the hidden page item P1_ORDER_ID.
Thanks!

Validation on Primary Key value in TMG

Hi,
I have a custom table with field Outcome_id as primary key. I have to put some validation on this primary key value.
For the above I hv used a TMG Event '01' and written the code for validating the values.
On save when validation fails the primary key field gets disabled even though entry is prevented from being saved.Since the value of the primary key cannot be changed the validation fails recursively.
How cn I keep the primary key fields enabled when the validation fail.
Rgds,
Swati.

Hi,
As per basic Module pool programming a screen field gets disabled after throwing an error.
You will have to use Field statement in the module pool program generated for your tables TMG and modify it.
But please note- any time TMG is regenerated all changes are lost.
"refering sap help "
Checking Single FieldsIf you send a warning or error message from a module mod that you called using a FIELDstatement as follows:
FIELD f MODULE mod.
the corresponding input field on the current screen is made ready for input again, allowing the user to enter a new value. If the field is only checked once, the PAI processing continues directly after the FIELDstatement, and the preceding modules are not called again.

How to get the auto increment integer primary key value of a new record

I have a DB table that has a auto increment integer primary key, if I insert a new record into it by SQL statement "INSERT INTO...", how can I get the integer primary key value of that newly created record?

Well maybe someone knows a better method, but one workaround would be to add a dummy field to your table. When a new record is inserted this dummy field will be null. Then you can select your record with SELECT keyField FROM yourTable WHERE dummyField IS NULL. Once you've got the key number, you then update the record with a non-null value in the dummyField. Bit of a bodge, but it should work...
Another alternative is, instead of using an Autonumbered key field, you could assign your own number by getting the MAX value of the existing keys (with SELECT MAX(keyField) FROM yourTable) and using that number + 1 for your new key. Might be a problem if you have lots of records and frequent deletions though.

EJB3: One-to-one relationships and auto-generation of primary key values...

Dear Forum,
I'm relatively new to JEE, and while I've so far enjoyed the convenience of EJB3 for most things, it seems that I have a corner case that can not be handled by the entity manager.
First, here's a quick mockup of my entities:
    Gallery
            |
            -- [1] -------[1] ----> Author
            |
            -- [1] -------[M] ---> Photo
                                              |
                                              -- [1] ------ [1] -> PhotoImage
                                                                                 |
                                                                                 -- [1] ------ [1] -> IPTCData
                                                                                 |
                                                                                 -- [1] ------ [1] -> EXIFDataI also have a remote, stateless session bean that does nothing more than persist()/merge()/remove() and locate (through find() and a few custom queries) my Gallery and Photo instances.
Now, the abridged version of my problem is this: when I persist a Photo, it naturally gets its primary key generated (I used @Id and @GeneratedValue). However, for some reason none of the other dependent entities inherit Photo's primary key value. In my client, I create a new Gallery locally and then persist it. I then create new Photo, PhotoImage, IPTCData and EXIFData instances. I add the IPTCData and EXIFData instances to PhotoImage (there are PhotoImage methods for adding those); then I add the PhotoImage instance to Photo (again, Photo has a setter for adding a PhotoImage). Then, I persist the Photo.
--- Aside: ------------
I've set up my relationships using annotations like @OneToMany (Gallery references a Collection of Photos), and @OneToOne (Photo's primary key references PhotoImage's primary key; PhotoImage's primary key references the primary keys of IPTCData and EXIFData). I've also added @JoinColumn annotations where necessary.
Finally, I get the Gallery instance's Photo collection (public Collection<Photo> getPhotos()), I add the Photo to the collection, and I add the Photo collection BACK to the Gallery (public void setPhotos(Collection<Photo>)).
At this point, the Gallery should have all of my entities contained inside of itself. However, when I persist the Gallery at this point, all of the entities show up in the database, but none of the primary keys get inherited. Photo's primary key gets generated automatically, of course, but the rest have zero (0) as their PK values. I had wanted, for example, IPTCData to get the value of Photo.id.
I had assumed that the entity manager would persist everything for me provided that I told it, through my annotations, about which entities relate to which. Does persistence only work in the direction of retrieval? That is, does the entity manager only do its thing when fetching (versus setting) data when there is more than 1 object in the graph? I can't believe that it can't, otherwise we'd all be ditching it and going back to straight SQL to do our work.
Thus, I HAVE to be doing something wrong, or else omitting to do something right.
I've made other incarnations of the above setup, and none of them have worked perfectly. I've even set up foreign key constraints in the database, but I had my share of unresolvable problems there, too.
So I guess my big question with all of this is: when you have a deeply nested graph of objects, can the entity manager figure everything out and persist all of the objects correctly and with the right values? If not, boo. If so, how does one accomplish this?
I know that I could persist each and every entity separately in my client code, but I wanted to have a natural-looking way of piecing all of my entities together. More specifically, I could persist IPTCData explicitly; however, I want to be able to add everything to a Photo and only persist the Photo itself, with the idea that all of the objects and sub-objects would be persisted automagically.
Is this possible? Or have I bought into a pipe dream with the guarantee of the proverbial magic bullet?
Thanks to everyone in advance for his/her input.
Regards,
Michael

Daniel,
Late last night I found the solution to my problem. And you're right, it had everything to do with which side is wired to which. I got confused about which side to consider the "owning" side, since one can look at it from the perspective of the database or the application.
Interestingly, the first 2 lines of your example code match my client code almost verbatim: First, I create a new Gallery (or else I get an existing one). I then create a new Photo and then add it to the Gallery's collection using add(). I then persist the Gallery. My session bean internally calls EntityManager.merge(gallery). How it differs from your example, though, is in the fact that, on an application level, a Photo has no knowledge whatsoever of a Gallery. Which is to say that my Photo class does not have a 'getGallery()' method. Somehow, Hibernate is able to figure it all out and still update Photo's 'parentIdRef' column in the database. My logs show that Hibernate issues a SQL UPDATE on the Photo after both a Gallery and a Photo have been created. It sets the Photo's 'parentIdRef' column to the primary key value of the owning Gallery.
Getting back to the matter, my problem was not with being able to map a Photo to a Gallery; rather, I was unable to add a PhotoImage to a Photo and have the relationship get correctly mapped in the database. The relationship between a Photo and a Gallery is many-to-one: there can be many Photo objects inside of a Gallery. In the database, a Photo row contains a 'parentIdRef' column whose value is that of a Gallery's primary key. I used @OneToMany on the Gallery, since a Gallery is, from an application perspective, the "owning" side, even though it's only the Photo that knows who it's referring to since only IT contains the 'parentIdRef' column in the database.
I tried setting up the relationship between a PhotoImage and a Photo in the same manner, with the PhotoImage having a 'parentIdRef' column and referring to a Photo's primary key. I had annotated the Photo's getPhotoImage() method with @OneToOne, along with an appropriate @JoinColumn.
It was THIS part that I had backwards. With a @OneToMany relationship, the child refers back to the parent --- it can be no other way. However, with a @OneToOne relationship, the owner refers to the child.
So, to make a long story short, all I had to do was create extra database columns for Photo. Those columns refer to the primary keys of PhotoImage, EXIFData and IPTCData. Concretely, for example, Photo.photoImageIdRef references PhotoImage.id. And so on and so forth.
The only negative side-effect of this is that my database-level foreign key constraints are now broken, since Hibernate wants to persist PhotoImage, EXIFData and IPTCData before it persists Photo.
I have to investigate more deeply the 'cascade=...' option of the @OneToOne annotation in order to find out it relates, if at all, to a database-level cascade.
Anyway, thanks for the reply. It seems that you had a very good idea about what my problem was. I would have posted the fact that I had resolved the problem last night, except that it was too late and I was heading to bed. If you still want the Duke points, let me know. I don't currently know the rules about if, when and to whom I should issue points in cases like these when I've already solved the problem.
Regards,
Michael

Creating a New Row Using an ADF Iterator Binding without primary key value

I dropped a Create action onto a DataAction which forwards to a UIX entry page which contains an enabled Commit button. Part of the primary key value is held in a session bean and it is also current in another view on the model side, but I am unable to access this value to set the EntityImpl primary key attribute.
Upon submission the following error message is returned from the model:
ORA-01400: cannot insert NULL into ("GTR"."EMPLOYMENT"."ACCOUNT")
I would like to accomplish this with databinding and not create a custom create method on the application model. Is there a way to update the binding value for the new row in cache before the submission? Any advice would be welcome.

I should add that I want the user to enter every attribute value, except for the account number. It must be possible to create a new row and have the account number supplied to the bindings another way.

How to Create process of Type : Get Next or Previous Primary Key Value

Hi,
Can anybody give the steps how to create the page process for type Get Next or Previous Primary Key Value in oracle Express database
Ramesh j c.

Hi Justin,
In oracle 10g XE , we have sample application v2.0
1. Do you have any Document to create step by step the sample application v2.0 and Is it possible to create all the pages of this sample application v2.0 b by wizard. To recreate or create the demo app, start from the home area,
next go to application builder,
then click the create button,
next choose "demonstration application"
and then you can choose "Run | Edit | Re-install" the "Sample Application" along with a few other apps.
2. When we install this sample application v2.0 , which is the sql script is executed or how it is installed. If you want the sample application you can export it after you create it if you want the SQL associated with it.
3. Whenever the sample application v2.0 is installed, how the encrypted pass word is created for the user demo and admin. This is setup with the application install. I don't believe it is encrypted either. If your wanting SSL there are some threads on here that talk about encrypting content.
Justin thanks for to create process Get Next or Previous Primary Key Value

Chaging primary key value when child record present

Please tell me how to change the primary key value when it's child record is present.

Well something like INSERT new primary key, UPDATE child records, DELETE old primary key would seem fairly obvious.
Using deferrable constraints may make the process rather simpler.
If on the other hand you are looking for UPDATE cascade functionality, Tom Kyte has an article regarding implementing this.

Hi,
I have 2 pages. In the first page on click of GO button, Im inserting data into table using EO and Immediately navigating to second page.
Primary Key value is generated in EOImpl java file.
In second screen, in the header region, I need to show the row inserted in table.
to query the VO, i need to have primary key generated in EOImpl.
Please let me know how can i get this value in either in PFR of first page or in PR of second page. Thanks.

Hi
have you included the eo that tyou are refering to in the header oif the second page..
if both pages are using the same AM, the data will appear.
at worse can you can get the ID from the eo using amethod in your AM.

Apex Form - how to enter primary key value manually?

Hi
Whenever I am creating Apex form using wizard, it asks me to specify trigger/sequence/pl/sql function for populating primary key value.
However, if I want to specify primary key myself (ie. not auto generated number), how I can specify that?
Thanx

Hello,
By Yourself you mean : by hand or by a pl/sql?
If you say by trigger, the system doesn't care about what number is send. So you can give it "manually"
May I ask what is the reason of that?
Cheers,
Arnaud
