Remove Entity from ERD Diagram

I have an ERD diagram with several entities on it. I have also
included an entity from another container on that diagram. But
no matter what I do, I cannot remove the included entity from
the diagram without deleting the entire entity.
How do I get rid of the entity on my ERD diagram without
deleting the entity? I've tried checking out/in every
combination of owning container, owning diagram, the entity
itself. I never get an option to delete the reference from my
diagram. I've been doing all this in RON. The erd diagrammer
tool only gives me the option to delete the whole entity.

Did you try to cut it? that is, you should Ctrl+X if you want
to get rid of an entity only from your ERD.

TL11g & EJB3: One-to-Many problems with removing entity from list

Hi,
I posted this problem on JDev11g forum, but I hope I will get some information here as well.
I have two entities based on tables in HR schema (Departments and Employees). Department has a list of employees. These are the annotations:
@Entity
public class Departments implements Serializable {
    @OneToMany(mappedBy = "departments", cascade = {CascadeType.ALL})
    private List<Employees> employeesList;
@Entity
public class Employees implements Serializable {
    @ManyToOne
    @JoinColumn(name = "DEPARTMENT_ID")
    private Departments departments;
}On a test page, I have a master-detail tables that show all departments and employees in the selected department (drag&drop from data control), a button that removes selected employee from employeeList iterator, and a button that calls em.merge(department).
The problem is that when I remove some employees from employeeList, on merge, the incoming entity, as well as the return result of the 'merge', are OK (the list doesn't contain the removed entities), but nothing is updated in the database, and no error is shown.
Can anyone help me with this? I can send the test case if anyone is interested.
Thanks,
Pedja

How to remove an object from a diagram

Hello,
Is there are way to remove (cut) an entity from a diagram (sub-view) in Data Modeler? I can only find a delete function which will delete it from the model altogether. I'd like to just remove the entity from the diagram and leave it in the model (and any other sub-views it may be in).
Thanks in advance,
Beatriz.

In my case, if an entity is shown in more than one views, a dialog box is displayed to ask if I want to completely delete the entity (from all views) or just hide it from current view.
You probably don't have your entity in multiple views. :-)

ERD diagram problem

I have created a new blank diagram in ERD (Oracle 9i Designer with newly installed designer repository).
When I click on New Entity icon an point a new entity rectangular on diagram 'Create Entity' window becomes available. Then after filling 'Name', 'Short name' and 'Plural' fields 'OK' button becomes available - just like in tutorial :) but when I click the 'OK' button .... nothing happens. Why? How? How to make a new entity? What I am doing wrong? 'Cancel' and 'Help' buttons work fine.

Try this:
After creating your entity, select from the ERD menu bar: "View" then "Zoom Out" -- or press together the CTRL and "-" keys. Repeat until you can see your entire diagram.

Strangely enough we can not see you so it really helps if you share with use exactly what you have, exactly what you did and details about the problem
what version of iPhoto and of the OS? What exact steps did you do? where are you seeing these "thousands of cascading photos" now and using what software and what exactly did you want to accomplish
The correct way to move your iphoto library to an external drive is to verify the drive is formatted Mac OS extended (journal) and then drag the iphotl library intact as a single entity to is
The correct way to move some or all of your photos is to select them in iphoto and export 9file menu ==> export -- https://discussions.apple.com/docs/DOC-4921 ) to the external drive

Removing entity

Hello
I am using Tomlink JPA as persistence provider for EJB3.
The problem has raised when I tried to remove some entities from a collection. As I have some exprience in Hibernate, I thought all the details entities will be removed when I remove them from the collection but soon I realized that in TopLink this is not the case.
now I am removing the entities individually, but the problem is that it seems the entity manager has removed the entities I declared but in database all the records are exists!!!
More stranger, in next execution the deleted entities are not loaded and everything seems ok but if I restart the application server all the removed data is coming back!!
after removing the entity I called entityManager.flush() and even I put TransactionAttribute for the value of REQUIRES_NEW but nothing has changed.
would you please help me on this problem?
thanks

Hi
I just found that, if I remove the REQUIRES_NEW from the delete() method of my DAO that works fine.
Would anyone explain me what happens here? As I have read, if you put REQUIRES_NEW the new transaction will start for that method and after exiting the method the transaction will be committed so my assumption is the data is visible to other transaction when it is going to read the same data (including removed records) but this is quite different from my understanding?

WCF Data services remove miliseconds from DateTime when expand

I get some strange behavior, when using WCF Data Services 5.6. In my case, I have table, with 1 column set with Concurrency=Fixed, and this column hold date time field from database, updated each time when row is edited. In case I just retrieve entity -
this column has correct value with milliseconds. But if I do mapping - milliseconds are removed.
Here is a issue at glance :
====================================================================
void Main()
var b = from p in TABLE1 where p.ID == 100 select p;
b.Dump();
Request in this case is : Data.svc/TABLE1(100M) And data returned from service is :
<d:COL1 m:type="Edm.DateTime">2015-02-16T12:13:52.972</d:COL1>
====================================================================
As you can see , here time is returned with milliseconds - .972 In other case :
void Main()
var tmp = from p in TABLE1 where p.ID == 100 select
new TABLE1()
ID=p.ID,
COL1=p.COL1
var a1 = tmp.ToList();
a1.Dump();
Request in this case is : Data.svc/TABLE1(100M)?$select=ID,COL1
<d:COL1 m:type="Edm.DateTime">2015-02-16T12:13:52</d:COL1>
====================================================================
Time is returned without milliseconds.
Does anybody have same problem? May be its a bug in the WCF Data services or in the model?

Ok, seems like I found an answer to this, or at least way to avoid the problem.
First I traced generated SQL from framework, and I see that in first case, im getting SQL
SELECT ID, COL1 FROM TABLE1
and in second case, I got
SELECT ID, CAST( COL1 AS DATETIME) FROM TABLE1
which cause the problem.
Then I tried to update EF to version 6, WCF Data services to version 5.6.3,
Oracle ODP to latest one, tried to use Oracle managed driver... no any success.
Then I played little bit with table definition, and I saw that my col1 with type TIMESTAMP in database and DateTime in the model was defined as NOT NULL.
If I remove this from database definition, I got right value with milliseconds.
So , may be this is a bug in Oracle driver, but probably this is a bug in the WCF Data Services. At least I found a way to use concurrency in my case with this solution.

DM 3.0.0.665: How to remove arc from relational model

When creating an arc in the logical model, "engineering to relational" will update the relational model so "DDL Preview" shows DDL for two triggers that enforce the arc.
After removing the arc from the logical model and "engineer to relational" I still see the trigger code in "DDL Preview", as if the arc is still there.
Where can I see the arc in the relational model, and how do I remove it from the model?
/ Marc de Oliveira
Edited by: marc66 on 2011-03-01 06:49

Marc,
you can see the arc on diagram - probably it's hidden. You can move some of parent tables and probably it'll appear. If still invisible then you can create subview and put child table and two parent tables on it - arc should appear and you can delete it.

Removing zeros from data stream

Hi
I have incoming data (plz see attached diagram which shows the 2 states of the for loop '0' and default) which is a 1-D array of 64 bit real data .....it goes through the loop which removes zeros from the array.
As I have 3 elements in the 1-D array (call them x,y,z ), the loop works very well for all values of 'y' and 'z' .
However when x gets towards 1 and below say 10e-3 (it never is a negative number), the loop is rounding everything to 1 and then when the value gets between 1 and 0 (10e-3 for example) the loop leaves it out altogether and I just get y,z values saved.
Plz help me sort this out .
Cheers
Baz

Temparally remove rows from a ADF table by action event of a jsf page.

Hello Developers,
I needed to temporally remove rows of a ADF table when execute action event of corresponding page.
So in this case my task can describe by following steps,
(1). I created a ADF table using <af:table> on a jsf page.
(2). The data populated using a VO.
(3). Several radio buttons added to the page for temporally remove rows from the table.
This means one radio button check, it responsible to temporally remove rows which contain empty cell values of a identified column.
If I check another radio button it should temporally remove identified data included rows but above removed (empty cell included rows) rows should appear in this event
My ultimate target is temporally remove rows of a table & re call again removed rows another event without again & again query from BC.
Pleas advice me to archive this task very sealy?
(Are there have a way to do this using EL or coding in Manage bean ?)
Thanks in advance..!

Hi,
the DCIterator gives you an option to iterate over the fetched rows (the ones you see in the table). You can try call removeAndRetain() on these rows. This will not remove or delete rows but allows you to insert these rows back to the collection.
JavaDocs:
* Removes the row from the collection and then retain it for insertion
* into another location.
* <p>
* This method differs from <code>{@link #remove()}</code> in that
* it just removes the row from the collection. It does not
* remove the underlying Entity row(s) or database row(s).
* <p>
* This method also differs from <code>{@link #removeFromCollection()}</code>
* in that after the row is removed from the collection, it can be inserted
* back into the collection at another location.
void removeAndRetain();

Pick queue item to work on, check "Also remove item from queue(s)" - where did it go?

We recently upgraded from CRM 2011 to 2015.
When users pick a queue item to work on, and check "Also remove item from Queue" - where does it go? I cannot find a view that lists these items anywhere???

Hi This depends on, which entity is in the queue. If it is an opportunity it could be found in opportunities If it is an email it could be found in activities etc. If you upgraded from crm2013, where could you find it before update to crm2015? Hope it
helps. Gr.peb

How do i remove money from 1 itunes account to another ?

How Do I Remove Money From One Itunes Account To Another ?

See: More Like This To the right -->

I've had three laptops all connected to my itunes account, one was stolen, the other broke, how can I remove them from my itunes account?

So, in three years, after getting an iphone and an apple account I've had to replace a laptop twice due to theft or damage. When I link my phone to my new computer, it asks me if I want to connect the computer with the phone and I say yes, but you can only have 5 devices connected to one account, since one was stolen, and the other laptop broke, how do I remove them from my account??

De-authorise all, then authorise the one you still have.
