View with Primary Key

Why view with PK ? That's need to row in view be referenced from other foreing key into other table. But can't enable PK from view onky RELY and NORELY attribute can be changed on this PK, if PK is not enable then it can't be reference by FK.
The questión is WHY Oracle allow create PK (not enabled and not validate) into VIEW when thist's redundant on PK from original table. ????
My proposs is make relation only with record with any condition (The VIEW) Only thist record are relation with another table. If this limitation aren true the view is not option to build this subset relation. The first option to solve this situation is make another table intermediate content rows with only one column (the PK field on original table).
Plz. ... another sugestion .. !!!!!
Thank in advanced !!!!

Any one plsssssss

Problem with object view with primary-key based object identifier

Hello!
I met such problem.
t1 is persinstent-capable class:
class t1 : public PObject { .... };
T1OV is object view, based on object table T1OT
I1 is primary key of the table T1OT.
Next code:
t1* t = new (conn, "T1OV") t1(...);
conn->commit();
try
t->markDelete();
conn->commit(); // exception throws here
Works fine if T1OV defined as:
create view t1ov of t1 with object identifier default
as select * from t1ot;
And throws an exception
"ORA-22883: object deletion failed"
if:
create view t1ov of t1 with object identifier (I1)
as select * from t1ot;
Such problem also occurs when object view is based on relational table/view (OID is primary-key based).
Also it occurs when
t->markModified() used insted of t->markDelete()
I am using Oracle 9i second release for windows and
MS VC++
Thank You

You can specify constraints on views and object views. You define the constraint at the view level using the out_of_line_constraint clause. You define the constraint as part of column or attribute specification using the inline_constraint clause after the appropriate alias.
Oracle does not enforce view constraints. However, operations on views are subject to the integrity constraints defined on the underlying base tables. This means that you can enforce constraints on views through constraints on base tables.
Restrictions on View Constraints
View constraints are a subset of table constraints and are subject to the following restrictions:
You can specify only unique, primary key, and foreign key constraints on views. However, you can define the view using the WITH CHECK OPTION clause, which is equivalent to specifying a check constraint for the view.
Because view constraints are not enforced directly, you cannot specify INITIALLY DEFERRED or DEFERRABLE.
View constraints are supported only in DISABLE NOVALIDATE mode. You must specify the keywords DISABLE NOVALIDATE when you declare the view constraint, and you cannot specify any other mode.
You cannot specify the using_index_clause, the exceptions_clause clause, or the ON DELETE clause of the references_clause.
You cannot define view constraints on attributes of an object column.

JBO-25014: Another user has changed the row with primary key oracle.jbo.Key

Hi,
I am developing a Fusion Web Application using Jdeveloper 11.1.2.1.0. I have a home.jspx page that has a ADF table built on efttBilling View Object. . When you click on one of the rows in the table, it will take you to detail.jspx where you can edit the row and save. When 'save' is clicked, stored procedures are executed to update/insert rows into few tables , and then go back to home.jspx where you need to see updated content for that row.
To get down to the exact issue, updates are made to the tables on which the efttBilling View Object is built using a stored procedure. Once this is done, I am trying to requery view object to see new content. But I keep getting JBO-25014: Another user has changed the row with primary key oracle.jbo.Key error. Following are the approaches I followed to query new results:
a. Executed Application Modules Commit Method. Created 'Commit' Action binding and tied it to homePageDef.xml. Called this binding from a view scope bean.
    BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
     OperationBinding operationBinding = bindings.getOperationBinding("Commit");
    Object result = operationBinding.execute();
   if (!operationBinding.getErrors().isEmpty())
    return null;
b. Marked 'Refresh on Insert' , 'Refresh on Update', 'Change Indicator' checkboxes for all the attributes in the entities associated with efttBilling View Object.
c. Tried to Requery View Object. Created a refreshViewObject method in Application Module Impl.java file, exposed this method to the client interface and created a invokeMethod Action binding in home.jspx
Code in Application Module:
public void refresheftTransactionsforBillingAccountViewObj1View()
    System.out.println("In eftTransactionsforBillingAccountViewObj1");
findViewObject("eftTransactionsforBillingAccountViewObj1").executeQuery();
Code in view scope bean
        DCBindingContainer bindings =
       (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
        OperationBinding operation =
        bindings.getOperationBinding("refresheftTransactionsforBillingAccountViewObj1View");
        operation.execute();
I have searched web, ADF forums and tried methods suggested in there but no sucess.
Could anyone please provide some insight in this issue. I have been battling with this since quite some time. I can provide you with the log file too.
Thanks!
Shai.

What code does your Commit method have .. can you try using the Commit executable from the AM itself instead ?
Also -

'Change Indicator' checkboxes for all the attributes in the entities associated with efttBilling View Object.
which all attributes you set this property for . it should just be for History columns as such.
Did you also check if this could be your scenario ?

Primary Key Materlized View and primary key in master tables

We are using Oracle 11g2 and I created a materlized view on several master tables. The master tables all have primary key, but I did not include all primary key columns in the defining query.
According to Oracle Manual e10592 Specify WITH PRIMARY KEY to create a primary key materialized view. This is the default ....
The master table must contain an enabled primary key constraint, and the defining query of the materialized view
must specify all of the primary key columns directly.My MV created OK and works. My question is what can be the impact on my MV? Could it hit the performance. It takes 40 minutes for the MV to be created and 5 minutes to refresh for single row insert in each mater table. I would like to see it refresh in seconds.

Retrieving rows from the mview is purely a function of the number of rows and indexing on the mview itself. Refreshing the mview wall time depends on the quality of the query used to refresh the mview. Whether you include PKs from the source table in the mview is of little, or no, consequence here. What matters is the execution path of the refresh query. Is there proper indexing on the underlying tables to support the joins. Did you use mlog$_s to enable fast refresh - are mlog$_s even usable for your mview. There are a number of possible causes to your problem and we do not have enough information to make an estimate of the problem.
BTW, if the mview could refresh in seconds w/o mlog$_s, you probably do not need an mview.

Another user has changed the row with primary key -Table changed externally

Hello,
I am facing the error: "Another user has changed the row with primary key oracle.jbo.Key[94 ]." during the delete operation.
User case scenario:
1. Added new row in the table.
2. Once new row is added to the the table, another application will update few columns in the newly added row based on some logic.
3. On the same session I am trying to delete the newly added row and getting above mentioned error.
I have added a "Button" in the table to partialRefresh the table to check the new values of the changed columns.
I have checked the forum and found many similar errors and tried the following but nothing helped.
1. By setting "Auto Refresh = True" for the view object.
Issue faced-> It worked fine but after few add and remove my db is getting to inconsistent state after which, I am not able to do any add/delete from my page.
Error: "Too many objects match the primary key oracle.jbo.Key". I have checked this and I am not getting this error when "Auto Refresh = False" even after multiple add and remove actions.
2. By Setting "Auto Refresh" the iterator associated with the page.
Issue -> Did not work at all.
Looking forward inputs from gurus.
Thanks
Abhijeet

Finally I found one solution to this problem at: [ http://www.avromroyfaderman.com/2008/05/bring-back-the-hobgoblin-dealing-with-rowinconsistentexception/|http://www.avromroyfaderman.com/2008/05/bring-back-the-hobgoblin-dealing-with-rowinconsistentexception/]
Simply overriding the lock() method in the entity object resolved issue. Kudos to the author.
Code:
public void lock() {
try {
super.lock();
} catch (RowInconsistentException e) {
refresh(REFRESH_WITH_DB_ONLY_IF_UNCHANGED | REFRESH_CONTAINEES);
super.lock();
But, Now my refresh button is not working as depend on the "Auto Refresh = True" to update the table.
Can anyone tell me how can I refresh the VO of my table from the button.
Thanks
Abhijeet.
P.S: I have already added the partial trigger but it is work not working as the data is cached in the VO. Removing the Cached property for the VO is creating other problems.

JBO-25014: Another user has changed the row with primary key...

Hello,
could you help me please with resolving this error "JBO-25014: Another user has changed the row with primary key..." - I am just getting a row from a view by bind "filter" variable, then I am assigning new values for some of the attributes - and trying to commit ..unsuccessfully..
View is based on Entity.
I saw directive for setting Entity's attributes as "update after insert / update" - but this did not help me.
Thanks in advance.

Hi
Please try this solutions:
One solution is to change the ADF BC locking behavior to optimistic instead of pessimistic. Choose the AM and click the Configuration context menu option. Select the LocalAM entry and go to the Properties. Scroll down to the locking setting and change the existing entry
If there is a trigger changing values, you need to mark those attributes (the ones that may be changed) as refresh after insert and/or refresh after update in your Entity Object.

Error on commit: Another user has changed the row with primary key : Rec_10

i am using jdev 11g R2
i implemented a master form and two detail tables on a jspx page
added createInsert, commit and rollback buttons
actions from these buttons all are executed from a bean
for entity attributes: refresh after insert and update are marked as checked
i am using login page for authorizing the user by getting the user information from user table
and then using the userid i am applying the setVisible property on some components at bean code
when i am inserting a new row there is no problem, here i am generating the new id like 'Rec_10', using a database sequence
but when i am trying to update a current record, it is showing the error --> Error on commit: JBO-25014: Another user has changed the row with primary key oracle.jbo.Key[Rec_22 ]
on clicking the commit button and also it is not updating the record on database

Insert row with datapages/bc4j problem with primary key

Hi everybody,
i tryed to insert a new row into a table with primary key (id) and therfore used a datapage, where there is a html-form and the data tag set attribute to get the data into the BC.
I also want to use a sequence for the primary key and made a trigger to insert the key-value before insert. but in this case it doesnt work. I also tryed to get the sequence to the BC -Layer (so that i can set the PK in the View OBJ already) with a View Object but I dont know how.
so what schould i do??
thanxx
Martin

There's a know issue, when creating a record with blob, the blob content won't show until committing. The blob is added too late, which means you're in trouble with not-null fields...
Sue, is this logged as a bug? And the dialog captions?

Mapping in OWB with primary key and foreign key relationship

Hi all,
I am new to this datawarehousing field. I have just started my career. I have to now create a mapping in owb where a table has a field which is a primary key of another table in the same staging area. If you guys could help me out with the a method it can be created that would be very helpful to me.
I thought of 2 ideas,
1. If I can use a look up, but then I am not sure if i can use a lookup for primary key, foreign key relationship. If I can use also, I do not know how to use that.
2. What if I can directly take that the first table and link the primary key of that table to the second table which uses that primary key of the first table as one of its fields.
I do not know how feasible these methods are. Please guys help me out.
Thanks in advance.

I have a similar case where table a and table b having relation but table a got inserted with data and table b is empty so there no values for foriegn key column in table b to realte with table a.
Now i want to load table b foriegn key with primary key column values of table a.
how can we do this in owb
thanks

Javax.ejb.ObjectNotFoundException: Bean with primary key '555' was not foun

When I delete a particular entity bean instance, i get the following exception:
javax.ejb.ObjectNotFoundException: Bean with primary key '555' was not found by 'findByPrimaryKey'.
But, the instance is being deleted from the database.
Anyone please help,
Thank u,

Greetings,
When I delete a particular entity bean instance, i get
the following exception:
javax.ejb.ObjectNotFoundException: Bean with primary
key '555' was not found by 'findByPrimaryKey'.Interesting. How is your client calling the bean's remove method? Directly or through its home? Is it calling findByPrimaryKey before or after the call to remove? What is the PrimaryKey class type of your bean? Is the client passing a correct instance? All are things to be considered when troubleshooting your application. If more assistance is required, then seeing the relevant source code would be more helpful.
But, the instance is being deleted from the database.As is generally to be expected. No?
Anyone please help,
Thank u,

The code is already there with JDBC call inserting
into the table, the inserting trigger then will generate
sequence key and being inserted into primary key column.
Now wondering if it's possible to change the code to use entity bean but without modifying the trigger (since it contains other business logics).

Another user has changed the row with primary key oracle.jbo.Key

Oracle Jdeveloper 11.1.2.1
ADFbc + JSF
I have a Page ( Purchase Order Status) (which show all PO to be approved) from this page (page1) the Supervison can call Regular PO (Page2) and change whatever he needs to change. (products, quantities, discounts,warehouse...)
then on Page2 he invoke (commit) after his changes and return to page1, when supervisor change the status to Approved on page1. I get this Error (Another user has changed the row with primary key oracle.jbo.Key[#]).
for sure there are no another user changing this PO.
both page are based on same Entity Object (PO) , how can I solve this Issue? thank you

hi,
This occur due to pessimistic locking mode for ApplicationModule ,alter to optimistic and check following sample to get knowledge about locking mode.

Another user has changed the row with primary key exception

Hi Experts,
I have a method in AmImpl.java. I am calling this method from my bean. The method opens a JDBC connection(i know it is not a good approach, we should use AM instance, but this was the last option as had tried all) and updates a table in the database. I want the data to be refreshed on screen after update is performed. So, I am doing VO.executeQuery() after i commit the data in the database and that is when i get the exception "Another user has changed the row with primary key exception".
Can you please tell me how to get rid of this error or any other way of doing the above process?

I have a screen divided into two parts, i have used a Panel splitter for that. Each pane has a table. Say i edit a record in table 1 and on the basis of changing a flag, the record should move out of table 1 and should go to table 2 in the second pane. the records in table 1 have some priorities defined by the end user, so if a record moves out or is reordered within that table, the rest of the records' priority number also changes. I have achieved all this. Now, when I apply a filter on the table, the record set gets filtered and contains limited set of rows. Now, when i try to achieve the two processes i have mentioned above (moving out or reordering), I need to have a control over the entire rowset because i need to alter the priority numbers accordingly but the VO iterator contains only the filtered set of rows even if I do VO.executeQuery. I was not able to get the entire rowset, so thats when i decided to use JDBC and i am able to successfully update the database. Then after the update, i need to refresh the table on the screen, so I did Vo.executeQuery in the bean after the method was called and I encountered this error. Then, I removed this Vo refresh from the bean and did this.getVO.executeQuery in the AmImpl method, after i commit changes in the database, it was working fine for few days but now it has started flashing the exception "Another user has changed the row with primary key exception".

Updateable columns with primary key

Hi,
I use HTML DB 2.0 and 10g R1.
With HTML DB i would like create an application with 2 pages.
The first page is an report from a table with 2 columns, the first column is datatype number(10) with primary key and the second column is varchar2(255).
The report should looks like with an edit-icon for all rows and both columns with header.
My problem is, the report has only 2 columns, not 3 columns and the edit-icon is together with the first table column, the header name is Edit.
What can I do ?
The second page should be a form linked from the first page for update, insert and delete rows. It's not possible to use a sequence on column with pk for new inserts.
I don't know, which sample application has the same content or what I have to do.
Who can help me ?

Simply create an application "Report and Form" based on your table and modify it as follows:
- On the report page, modify the query to include the PK column a second time (using an alias)... if this was based on the EMP table with EMPNO being the PK, the query then looks like this (modification bold):
select
"EMPNO",
"EMPNO" as "EMPPLOYEE NUMBER",
"ENAME",
"JOB",
"MGR",
"HIREDATE",
"SAL",
"COMM",
"DEPTNO"
from "EMP"
where
instr(upper("ENAME"),upper(nvl(:P1_REPORT_SEARCH,"ENAME"))) > 0 or
instr(upper("JOB"),upper(nvl(:P1_REPORT_SEARCH,"JOB"))) > 0
- In the report attributes, move the added column to the desired position (I moved it directly next to the edit link).
- On the Form page, just change the item holding your PK column from "hidden" to "Text field".
You may take a look at http://htmldb.oracle.com/pls/otn/f?p=PK_VISIBLE:1 to verify this is what you're looking for.
Edit: Oops - I just recognized I cannot update the EMPNO on page 2 since the automated row processing depends on an unchanged PK. However - normally it isn't a good idea to update a PK anyway (since it might be used as FK in some other table(s)).
It is possible to create new records with manually adding the new PK, so if this is really all you need, then I would suggest you modify your edit page displaying the PK column read-only when editing an existing row and updatable when adding a new record (using 2 items with conditional display, based on the PK being NULL or NOT NULL).

Another user has changed the row with primary key oracle.jbo.Key HELP

I created VO which based on two entities. Then user search from that VO, when result comes update two row of each entity .
HERE my function
public String lockPayment() {
getAppImpl().getcheckPaymentsVO1().setRangeSize(-1);
Row[] rw2 = getAppImpl().getcheckPaymentsVO1().getAllRowsInRange();
checkPaymentsVORowImpl tparow;
tparow = null;
for (int j = 0; j < rw2.length; j++) {
tparow = (checkPaymentsVORowImpl)rw2[j];
// tparow.setApayLock("1");
tparow.setAtaxLock("1");
BindingContainer bindings = getBindings();
OperationBinding operationBinding = bindings.getOperationBinding("Commit");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
return null;
When I click it gives me error:
----------> Another user has changed the row with primary key oracle.jbo.Key
Any suggestion !!!!!!
