Easily Data model change.

Sometimes we need to change project data model after creating Bussiness Comp diagram.
fro example Add new column to the table, change relation etc.
So we need to change entity, view and application module objects
Is there any easy way to make this.
such as refresh model from database.
we are using 10.1.3.1.
thanks...

Right clicking on an entity object and choosing synchronize with database will look up the DB structure for any changes related to the entity and will allow you to add/delete attributes as needed.

Using CVS in SQL Developer for Data Modeler changes.

Hi,
I am fairly new to SQL Developer Data Modeler and associated version control mechanisms.
I am prototyping the storage of database designs and version control for the same, using the Data Modeler within SQL Developer. I have SQL Developer version 3.1.07.42 and I have also installed the CVS extension.
I can connect to our CVS server through sspi protocol and external CVS executable and am able to check out modules.
Below is the scenario where I am facing some issue:
I open the design from the checked out module and make changes and save it. In the File navigator, I look for the files that have been modified or added newly.
This behaves rather inconsistently in the sense that even after clicking on refresh button, sometimes it does not get refreshed. Next I try to look for the changes in Pending Changes(CVS) window. According to the other posts, I am supposed to look at the View - Data Modeler - Pending Changes window for data modeler changes but that shows up empty always( I am not sure if it is only tied to Subversion). But I do see the modified files/ files to be added to CVS under Versioning - CVS - Pending Changes window. The issue is that when I click on the refresh button in the window, all the files just vanish and all the counts show 0. Strangely if I go to Tools - Preferences - Versioning - CVS and just click OK, the pending changes window gets populated again( the counts are inconsistent at times).
I believe this issue is fixed and should work correctly in 3.1.07.42 but it does not seem to be case.
Also, I m not sure if I can use this CVS functionality available in SQL Dev for data modeler or should I be using an external client such as Wincvs for check in/ check out.
Please help.
Thanks

Hi Joop,
I think you will find that in Data Modeler's Physical Model tree the same icons are used for temporary Tables and Materialized Views as in SQL Developer.

Customized table cell renderer doesn't work after table data model changed

Hi:
I have a jtable with a custimized table cell render (changes the row color). Everything works fine while the data model is unchanged. I can change the row color, etc. However, after I delete one row or any number of rows in the table, the data model is updated and the custmized table cell renderer is not being called anymore while jtable is rendering on its cells. Seems like the table cell render is no long associated with the jtable. Is this a known problem? Any help would be appreciated.
Thanks

I am having the same problem. Has anybody solved this issue?
Thanks

JList data model, MVC, is there an example?

I have a JList, constructed from an AbstractListModel based on an ArrayList, tucked into a JScrollPane. The data model changes frequently en masse, not element by element. I have studied the API documentation of ListModel, ListDataListener, and ListDataEvent. I want to update my Jlist without reconstructing the whole thing, JScrollPane and all, and adding that JScrollPane to a JFrame's content pane in a method called from a distant class. That approach is just not working in the details like screen redraws, no matter the combination of validate(),repaint(), and show() calls I make.
The data in the ArrayList is there, I'm just trying to notify the AbstractListModel in the JList in the JScrollPane that the data has changed, so presumably it can take care of displaying those changes. The search function for similar posts on the forum is not working for me, and I am running out of resources to study on my own. A set of tutorials by by Dick Baldwin
http://www.phrantic.com/scoop/onjava.html
has been the most helpful by far in explaining MVC and its application to JList, but he says,
"fortunately we can avoid having to deal with the complexity of creating and maintaining a list of registered listener objects, and invoking listener mithods on those objects, by extending AbstractListModel to create our alternative data model..." I don't want complexity either, but I do want to update a data model.
I need an example of how to use these methods, like addListDataListener(ListDataListener l), fireContentsChanged(Object source,int index0, int index1),
public ListDataEvent(Object source,int type, int index0, int index1)
I can't believe that what I want to do is that uncommon or esoteric. Maybe it's just that I'm not seeing something obvious.
Any pointers?

Stated differently:
Here's the API and my error message and my code: is there a way to have just working code and the API, without the compiler error? (recs in the code is my data model, allRecs is the ArrayLIst it's based on)
API
fireContentsChanged
protected void fireContentsChanged(Object source,
int index0,
int index1)
AbstractListModel subclasses must call this method after one or more elements of the list change. The changed elements are specified by a closed interval index0, index1, i.e. the range that includes both index0 and index1. Note that index0 need not be less than or equal to index1.
Parameters:
source - The ListModel that changed, typically "this".
index0 - One end of the new interval.
index1 - The other end of the new interval.

How to get data model to recognize structure change

I have an extremely complex report that was built almost entirely manually -- except for using the Data Wizard to create the Data Model (multiple queries with multiple groups). The source view that the query Q-1 is based on has changed. It is a change in the precision of the column. How do I get the data model to notice that change? The Width in the Property Palette is still showing 8 when it should now be 16. This is causing the display on the report to be truncated to 8 characters.
I don't want to have to rebuild the data model. It took me 3 days to get it so that it works!
Thanks

PLS OPEN THE QUERY AND THEN CONNECT USING YOUR USER. I THINK WHEN YOU REFRESH THE QUERY AND CONNECT THEN WIDTH IS CHANGE AS THE COLUMN IN THE DATABASE.(i.e. 16)
THANKS,
FAROOQ Thanks for the suggestion. Unfortunately, the same thing happens when I do this as happens if I modify the query with a space (as before); the rows are removed from their groups, and I lose the Source of my calculated fields.
If anyone is interested, I finally found a way to do this:
1. Convert the report into a text file (File>Administration>Convert);
2. open the text file in a text editor;
change the offensive WIDTH settings (make sure to look for all of them);
3. save the text file;
4. then convert it back to a RDF file using the converter.
A round-about way to perform what should be an automatic operation -- but there it is.

Crashes when changing editing data model

Reports 6i crashes (My windows (Unix) disappears) often when I am changing the data model (i.e removing and adding columns). I did figure out one thing and that is you when you delete a column that has a data link without removing the data link first it will not remove the column and the report will crash when you attempt to make an additional changes to that query that was changed. Any additional reasons?

Kathy,
Suggest you log a TAR with Oracle Support on this issue. The builder should not be crashing and I did not find any bugs logged. They will need to reproduce the problem and log a bug if necessary. You will need to supply them with the specific version of Reports and the operating system.

Oracle Data Modeler commit change seg physical table

Hello,
Sometimes when I record a data model, Oracle Data Modeler (SVN) given as outgoing a chage of segment of physical table , if you committees are to change, duplication of files in the physical model is produced. Later when you open the physical model gives errors that have duplicate files
How you can correct this error? Why the segment change occurs?
Thanks

Hello,
Versión 4.0.0.833.
No pattern is occasionally when shooting in the data model. How you can correct this error? Why the segment change occurs?
Thanks

Power View Enhancement Request - Allow for columns to drop off PowerView when column name changes in data model instead of rendering the PowerView inaccessible

Currently in PowerView, if a column name changes in the tabular model, and that column is being used in a PowerView chart, the PowerView will become inaccessible.
It would be nice if it functioned similar to Pivot Table. If a column name changes for a column that is being used in a Pivot Table, the field is just removed from the chart, and the user can select the newly named column.

Hi plantm,
After testing the issue in my environment, I can reproduce it. After we change a column name which is used in a Power View chart, Power view will render the message that” The external data connection has been disabled for this Power View report. Please enable
the connection.” when we reopen the file.
To fix this issue, we can click Refresh button under POWER VIEW menu, then it would prompt us that” Power View was not able to complete the action due to a query failure. This can happen if the structure of your data has changed, in which case closing and
re-opening the application will resolve the problem.”
According to the error message, we should try to reopen the file to fix this issue. Power view will render the message that” Please refresh to see the data for this Power View Sheet. You can set properties in the Connection Properties dialog so that the
data refreshes automatically when you open the file.” when we reopen the file. Then we can refresh it again, the report will be displayed without that field.
Based on my research, inherently what the message means is that Power View cannot be used as a tool for snapshot reporting. With an Excel PivotTable, we can see the data last saved in the PivotTable. Power View, however, does not behave the same way – it
won’t render the last saved state. If we want to avoid this message when we reopen the file, there are two methods:
When we create the Power View report, we can select the checkbox that “Refresh data when opening the file”.
After it’s been set up, go to Connections on the Data menu, then choose Properties.
For more details about the settings, we can refer to the following blog:
http://www.sqlchick.com/entries/2013/3/30/creating-a-power-view-report-in-excel-2013-which-uses-an-ext.html
Hope this helps.

Data Modeler Incremental Database Changes

We need the tool to determine the differences between the database and the model, so that it generates DDL only for the changes without us having to tell the tool at DDL creation time which are the new tables, columns, indexes, etc. Is this feature available already or would this be a new feature?

Hi,
Yes, this feature is already available.
If the model was initially imported from the database, you can use Synchronize Data Dictionary with Model (either for individual objects, or for the whole model using the right-pointing arrow above the diagram).
This displays the Compare Models dialog identifying the differences. You can use its DDL Preview button to generate DDL to update the database.
There's a short video demonstrating this at http://apex.oracle.com/pls/apex/f?p=44785:24:689545084496101::NO:24:P24_CONTENT_ID,P24_PREV_PAGE:5951,2
If the model was not imported from the database, you can do the following:
Open your model (including the relevant Physical Model).
Use Import/Data Dictionary to start the Data Dictionary Import Wizard. In step 2, select the "Swap Target Model" tick box. And select the relevant objects to import from the database.
After the import phase, this will display the Compare Models dialog as in the previous case.
There is now a forum specifically for Data Modeler topics: SQL Developer Data Modeler

Data modeler saving Physical model changes not saved

I am using version 2.0.0.584.
The bug fix list contains: 8722310: Save does not save physical model changes
Hovever I still see unexpected behaviour.
I created a physical model for "Oracle database 10g" and allocated a couple of tables to a different tablespace.
I saved the physical model via Physical model--> right mouse button --> save all.
I saved the model with File--> save
I close the model.
After opening, the physical model is not available anymore.
After Physical model--> right mouse button --> open (for Oracle 10g) the contents are not the same anymore.
Tablespaces with name "TableSpace3" and "TableSpace4" are added and objects belong to this tablespace.
We do not have currently a workaround for this behaviour.
Can anyone help?
Thanks

Hi Philip,
default tablespaces were defined and I removed this. It did not have a positive effect.
Checking the log files was a good idea.
The log file contained errors about files which could not be found on the system.
I will do some additional tests and let you know.
Thanks.
Kind regards,

Sql Developer Data Modeler all domains lost after changing to version 3.0

I have two questions:
1. Sql Developer Data Modeler - is it still a separate product? Or is it only available as integrated within Sql Developer?
2. After opening a model created with Data Modeler 2.0 with the new integrated Data Modeler 3.0 I lost all my domain definitions. What can I do to avoid this? Any help would be appreciated.
Thanks in advance
Holger

Hi Holger,
Sql Developer Data Modeler - is it still a separate product? Or is it only available as integrated within Sql Developer?Standalone version is here http://www.oracle.com/technetwork/developer-tools/datamodeler/overview/index.html
2. After opening a model created with Data Modeler 2.0 with the new integrated Data Modeler 3.0 I lost all my domain definitions. What can I do to avoid this? Any help would be appreciated.Copy file defaultdomains.xml from DM 2.0 installation to "sqldeveloper\sqldeveloper\extensions\oracle.datamodeler\types" directory (if you use version in SQL Developer) or to
"datamodeler\datamodeler\types" if you use standalone DM 3.0.
Location of this directory can be set in preferences - it's called system types directory there - it contains: default domains, RDBMS sites, logical types and custom scripts.

Can you change the data model query dynamically based on its parent query

Hi
Question:
I have a data model query q1 and q2 is the child of q1
Say q1 returns 2 rows and and
for the first row
i want q2 to be select 1 from table1
for the second row
i want q2 to be select 1 from table2
Basically i want to build the q2 dynamically
for each row fetched in q1.
Can this be done?
If so where do i write the code to achieve this
Thanx in advance.

One simple (but not very realistic) example:
1. DATABASE TABLES AND DATA
CREATE TABLE dept_all (
deptno NUMBER (2),
dname VARCHAR2 (20),
in_usa CHAR (1) DEFAULT 'Y')
INSERT INTO dept_all VALUES (10, 'DEPT 10', 'Y');
INSERT INTO dept_all VALUES (20, 'DEPT 20', 'N');
INSERT INTO dept_all VALUES (30, 'DEPT 30', 'Y');
CREATE TABLE emp_usa (
empno NUMBER (4),
ename VARCHAR2 (20),
deptno NUMBER (2))
INSERT INTO emp_usa VALUES (1001, 'EMP 1001', 10);
INSERT INTO emp_usa VALUES (1002, 'EMP 1002', 10);
INSERT INTO emp_usa VALUES (3001, 'EMP 3001', 30);
INSERT INTO emp_usa VALUES (3002, 'EMP 3002', 30);
CREATE TABLE emp_non_usa (
empno NUMBER (4),
ename VARCHAR2 (20),
deptno NUMBER (2))
INSERT INTO emp_non_usa VALUES (2001, 'EMP 2001', 20);
INSERT INTO emp_non_usa VALUES (2002, 'EMP 2002', 20);
2. DATABASE PACKAGE
Note that Oracle Reports 3.0 / 6i needs 'static' ref cursor type for building Report Layout.
So, in package specification we must have both ref cursor types, static for Report Layout
and dynamic for ref cursor query.
CREATE OR REPLACE PACKAGE example IS
TYPE t_dept_static_rc IS REF CURSOR RETURN dept_all%ROWTYPE;
TYPE t_dept_rc IS REF CURSOR;
FUNCTION dept_query (p_where VARCHAR2) RETURN t_dept_rc;
TYPE t_emp_rec IS RECORD (
empno emp_usa.empno%TYPE,
ename emp_usa.ename%TYPE);
TYPE t_emp_static_rc IS REF CURSOR RETURN t_emp_rec;
TYPE t_emp_rc IS REF CURSOR;
FUNCTION emp_query (
p_in_usa dept_all.in_usa%TYPE,
p_deptno dept_all.deptno%TYPE)
RETURN t_emp_rc;
END;
CREATE OR REPLACE PACKAGE BODY example IS
FUNCTION dept_query (p_where VARCHAR2) RETURN t_dept_rc IS
l_dept_rc t_dept_rc;
BEGIN
OPEN l_dept_rc FOR
'SELECT * FROM dept_all WHERE ' || NVL (p_where, '1 = 1') || ' ORDER BY deptno';
RETURN l_dept_rc;
END;
FUNCTION emp_query (
p_in_usa dept_all.in_usa%TYPE,
p_deptno dept_all.deptno%TYPE)
RETURN t_emp_rc
IS
l_emp_rc t_emp_rc;
l_table VARCHAR2 (30);
BEGIN
IF p_in_usa = 'Y' THEN
l_table := 'emp_usa';
ELSE
l_table := 'emp_non_usa';
END IF;
OPEN l_emp_rc FOR
'SELECT * FROM ' || l_table || ' WHERE deptno = :p_deptno ORDER BY empno'
USING p_deptno;
RETURN l_emp_rc;
END;
END;
3. REPORT - QUERY FUNCTIONS AND DATA LINK
FUNCTION q_dept RETURN example.t_dept_static_rc IS
BEGIN
-- "p_where" is a User Parameter
RETURN example.dept_query (:p_where);
END;
FUNCTION q_emp RETURN example.t_emp_static_rc IS
BEGIN
-- "in_usa" and "deptno" are columns from Parent Group (G_DEPT)
RETURN example.emp_query (:in_usa, :deptno);
END;
Of course, we must create Data Link between Parent Group (G_DEPT) and Child Query (Q_EMP).

Latest PowerQuery issues with data load to data models built with older version + issue when query is changed

We have a tool built in excel + Powerquery version 2.18.3874.242 - 32 Bit (No PowerPivot) using data load to data model (not to workbook). There are data filters linked to excel cells, inserted in OData query before data is pulled.
The Excel tool uses organisational credentials to authenticate.
System config: Win 8.1, Office 2013 (32 bit)
The tool runs for all users as long as they do not upgrade to PowerQuery_2.20.3945.242 (32-bit).
Once upgraded users can no longer get the data to load to the Model. Data still loads to the Workbook but the model breaks down. Resetting load to data model erases all measures.
Here are the exact errors users get:
1. [DataSource.Error] Cannot parse OData response result. Error: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
2. The Data Model table could not be refreshed: There isn't enough memory to complete this action. Try using less data or closing other applications. To increase memory available, consider ......

Issue while creating Data Model in BI Publisher and logging into xmlpserver

Hi All,
We are facing an issue in OBIEE 11.1.1.5.
If we are logging with Non Admin Id (other than weblogic) and select New Data Model, a blank screen is coming. Where as, if we use Admin Id, we are getting screen as usual for creating data model. There were some blogs mentioning to change Priviledges for SOAP access, but that approach is also not working.
Further, we are also not able to open xmlpserver with Non Admin Id.
Any help or pointers would be great.
Regards,

how about pasting the content of your data template here, so that forum members can see what could be the problem.

2) In options to manage the Table report (Reports -> Manage). Currently I can only remove a heading (like Descriptions Notes ,columns,column comments.). Is there is any way to customize the report in such a way that I can remove some columns (mostly the empty ones) from the report and add the column comments along with the column table than a new column comments table.
Please let me know ,is there is an option to customize the report .
Note: I even tried generating the report using the search then report , but it doesn't give a complete report (i was only able to generate a report on column or table name or constraints , not all together.)
Thanks,

Thanks for the immediate reply.
I checked on the DM again, the report comes good for the one which has the data type . But now all my data type changed to UNKNOWN and lokks like ,due to this my table report is coming without the "Data Type".
