XCode 4.02 data model editor -- How do I delete an entity?

How does one delete an entity from the data model editor in XCode 4.02?
I have searched for the past hour for a little "minus" button hidding somewhere on the screen.

Switch Editor Style to 'Graph' from 'Table' (lower right of the editor window).
Select the entity you want gone...tap once so it shows focus.
Hit the 'Delete' key on your keyboard. 'Undo' if you want it back.

Missing toolbar in data model editor

Hi,
I just received an rdf file from one of my collegues.
i can open the file without any problems but when i go to the data model tool i don't see any tool bar.
it impossible to add any placeholder columns and so on without this tool bar, because i'm not allowed to add any object from the object navigator either.
i'm allowed to delete objects though.
tool version is reports 6.0.8.11.3
when changing to the layout editor i see the toolbar and when i start a new report from scratch the tool bar appears.
any help greatly appreciated.
thanx
kim

having worked with reports quite a lot i wasn't aware
that you could toggle this toolbar on and off.But I also have forms where the toolbar tunrs itself off for no apparent reason. And yes, you can turn it back on with the View menu, but that doesn't explain why it is disappearing.

BIP 11g: Data Model Editor bug?

In BIP 11g, trying to create a data model with single query with following SQL:
SELECT to_char(SYSDATE, 'HH24:MI') start_time FROM DUAL
The Create Data Set - SQL window does not like the above SQL. Specifically, the format mask HH24:MI is not recognized and give the error ORA-01756: quoted string not properly terminated.
Anyone seen this?

I think it's "11835845 - 11G SQL DATA SET CREATION ORA-01756 ERROR BECAUSE COLON IS READ AS BIND VARIABLE" bug
You can use CHR(58) instead of a colon.

Data model editor cannot save samle XML data if data contains angle bracket

BI Publisher can correctly query data containing angle brackets, and it produces well-formed XML in that case. Angle brackets are correctly coded as &lt and &gt. However, if you try to save the generated XML as sample XML for the data model, BI Publisher will issue the following error in its log:
[2012-02-17T14:12:07.491-08:00] [AdminServer] [ERROR] [] [oracle.xdo] [tid: 30] [userId: <anonymous>] [ecid: 4d7950b0e2efed24:2a9da7a7:135894f9533:-8000-0000000000002f73,0] [APP: bipublisher#11.1.1] End tag does not match start tag '...'.
where '...' would be any characters appearing between the open angle bracket and the close angle bracket. The sample XML data will not save, so you cannot open the report in the Desktop TemplateBuilder for Microsoft Word.
Note that this bug is not fixed in the latest February patch for version 11.1.1.5.

ok...tell me this, are you saying you are encoding the angle brackets or bi publisher is doing it automatically????
With the data I worked, & (ampersands) were more predominant and I replaced the columns containing them with +& a m p ;+ (without spaces) and everything was fine....

BIP 11g: Data Model Editor question

In BIP 11g, when you create a parent query q1 and link it to child query q2, is it possible to refer to column from q1 in the select list of q2? Oracle Reports allows this and I am trying to re-create this Oracle Report to a BIP report and this does not seem to work...i.e.
q1: select a.col1 col1_q1, a.col2 col2_q1from table_a
q2: select b.col1, b.col2, round(:col2_q1/b.col3) calc from table_b
while creating q2, the calculation refers to :col2_q1 which is the 2nd column of the parent query q1, BIP asks confirmation to create a bind variable for col2_q1. These type of references are common in Oracle Reports.
Is there any workaround for this?
Thanks,
Manish

Hi guys.
I got the all new MacBook Air 11" with Lion yesterday, and would like to sell the previous model (it was with SnowLeopard).
What do I have to do to delete everything, including my account? Do I need the SuperDrive or is it possibile without one?
Thanks!

Erase and Install OSX Snow Leopard http://support.apple.com/kb/HT3910
And yes, you need the SuperDrive for this.

Open a Write window. If all the toolbars are missing press the alt key to make the menu bar appear.
From the menu bar select View-Toolbars and turn the missing toolbars back on.

How do you delete a fetch request in XCode 4?

I'm a new user of the data model editor in XCode 4. How do I delete a Fetch Request which I don't want? It was difficult to figure out how to add one (click and hold the "Create Entity" button!). But now that I've created one, I can't for the life of me figure out how to get rid of it.
I'd also appreciated pointers to a good tutorial on building predicates. eg something which answer how do you test if the year in a date attribute == something.

You'd think I would have tried that. Select the request and then do Edit->Delete offers to delete the entire data model. I always thought the Delete key and Edit->Delete were equivalent. I guess not. Thanks.

Data model: single quote in default parameter value

Hello,
when I assign a default value to a parameter in my Data model, which includes a single quote (i.e. "It's a default value"), then the single quote is escaped with a backslash (i.e. "It\'s a default value") when I open the report associated with the data model. How can I get rid of the escape character when opening a report?
Regards,
Jure

Hi Yogini,
Thanks for your reply.
When the customer name is selected, discoverer reports automatically enclose the customer names in single quotes. like 'ABC LTD', 'ABC's INC',
I know how to change this single quote format. Also we don't want user to change the parameter selection criteria once selected.
Also related to double quotes isn't it doubles are treated as column names in the SQL query and can not be used for any other purpose.
Apologies, I haven't tried this but I think it will not work. Have you tried this with discoverer viewer.
As mentioned intrusting things is when a customer name with single quote is selected in discoverer Plus it automatically formats the filter criteria to look like ['ABC LTD', 'ABC''s INC'] but this thing doesn't happen in viewer.
I think this is a bug in discoverer viewer and think there must be some patch available to correct this problem.
Sorry, don't have a solution yet but will certainly update the thread once I get the solution.
Also please keep looking for a solution and let me know as well.
Thanks a lot in advance.

Path direction in Oracle spatial network data model

Hi all,
can any one help me how to implement path direction using oracle network data Model?
We are using Oracle Spatial database. there is one feature called network constraint in Network data Model. but how to implement path direction of my Network ? Please help me any one

The path direction in a Spatial network is enabled at creation time when calling the create network procedure such as SDO_NET.CREATE_LOGICAL_NETWORK. If you describe the Create procedure you're using you should see a IS_DIRECTED argument, which when set to TRUE will enable path direction. Then just ensure that your links are created in the right direction -specifying correct orientation for start node and end node.
Cheers,
Stuart.

BI Publisher Report with Multiple data models

I have an Oracle Report with two different data model(querys) and Layouts for Summary and Details. When the user Choses Summary it execute the summary data model query and display the result in summary Repeating frame Layout and when user choses Details it execute the other query and uses the other layout.
Now I am creating the same report in Stand alone BI Publisher. As a company standard we are using Data Template for Data model. How can I accomplish the same feature I mentioned above in BI Publisher? Meaning How can I control and execute the querys in BIP based on a parameter "Summary" or "Details" ?
Can Someone help
George

option1:
The query should be same @ detail level, only the template has to be different for summary and details.
@runtime, user can choose to see the detail/summary
Disadvantage, if the data is huge,
advantage , only one report.
option2:
create two separate reports summary and details
and create diff data and diff layout and keep it as different report
Advantage, query will perform based on the user run report, summary/detail, so that you can write efficient query.
Dis advantage , two reports query/template to be maintained.
