SQL Datamodeler: Relational model: column properties: formula description

Hello
When I navigate to the column properties of a formula column I can add a formula description.
This formula description is not picked up by the DDL generator (Oracle).
What am I missing?
Regards Erik

Hi Erik,
if you put something there it will appear on diagram instead of data type (for good or bad). There will be more usage when support for virtual columns in Oracle 11g is implemented.
Best regards,
Philip

SQL Datamodeler: engineer to relational model: column names

Hello
Suppose I have an attribute called DAY OF BIRTH. Is there a way I can forward engineer this attribute to a column name DAY_OF_BIRTH?
(I know you could have a coulmn name "day of birth" but thats not what I want)
Regards Erik

Hi Erik,
1) you should check separator settings in General options>Naming Standard -it should be "space" for Logical model and "underscore" for Relational model;
2) "Apply name translation" should be selected in engineering dialog

Data Modeler Columns Properties

When I validate my relationel design the tool warns me that all columns have undefined security properties.
That is correct, but I cannot configure the security properties in a general way ie default values for all columns it seems. Do I really have to configure this for each column in order to get rid of the warnings?
The tool Help is not of must help here, since a search for the term "security" does not give any hit in the Help. All security properties are seem undocumented in Data Modeler

The idea is to not have default setting for security properties. You can change them in table dialog (columns page).

Sql datamodeler: Engineer to relational model: General Options

Hello
When you engineer your logical model to a relational model you get a wizard. In lower part of this wizard byou have several tabs, one of the tabs is called general.
On this general tab you have check box: Apply Name Translation
The corresponding help text:
Apply Name Translation: Controls whether formal names are translated to abbreviated names when the logical model is forward engineered to a relational model, and whether abbreviated names are translated to format names when a relational model is reverse engineered to the logical model. Name translation is applied only for valid names. In addition, translations between the words entity/attribute/key and table/column/index are performed.
Does anybody have a clue what is meant here?
Regards Erik

Erik,
you have to create glossary (tools>Glossary editor) with words permitted for usage in names in logical model. For each word you can define abbreviation that will be used in transformation process.
Example:
Employee - EMP
Salary - SAL
Attribute "Employee Salary" will be transformed to column "EMP_SAL".
You can define preferred abbreviation for entities and attributes and it can be used instead of glossary definitions.
You also have to set your glossary in "Tools>General Options>Naming standards>Glossary"
Best regards,
Philip

SQL Developer Data Modeler "Reports" Duplicate Columns in Index- Bug

I am using SQL Data Modeler of SQL Developer - 3.2.20.09
Problem Description:
In the "Indexes" section of report generated for a table, column appear twice.
Steps to Reproduce:
1. Create an Entity in Modeler: COMPANY, Add attributes COMP_ID and COMP_DESC to it, mark COMP_ID as PK
2. Engineer it to Relational Model
3. Go to 'File->Data Modeler->Reports'
4. Select 'Available reports' = 'Table' and press 'Generate Report'
5. View the report.
Indexes shown for the table contains duplicate columns for COMP_ID

SQL Developer Data Modeler - Relation to Foreign Key Generation

SQL Developer Data Modeler 2.0.0 Build 584.
I am having trouble with Relations to Foreign Keys when Forward Engineering a Relational Model from a Logical Model.
First of all, the Naming Standard is not applied to the Foreign Keys when I perform the Engineer to Relational Model.
So I right click on the Relational Model from the Browser and Apply Naming Standards to Keys and Constraints.
I uncheck everything but Foreign Keys.
Now, Foreign Keys are named according to my Naming Standards.
However, this process also performs renames on the Column Foreign Keys even though I specifically unchecked that option.
This appears to be a BUG in the software and I haven't found a way around it.
I tried using {column} instead of {ref column} in the Naming Standard Template for Column Foreign Key, but that simply resulted in renaming my columns to "{column}".
Please confirm and/or let me know of any work-around for this.
Thanks,
Dan

Hi Philip,
Thanks for the reply.
Is this recorded as a bug to be addressed in the future?
Should I submit this problem via Oracle Support?
The other work-around I came up with is to override every Relation name in the Logical Model with the name I want to use in the Relational Model.
When the Relational Model is Engineered, this becomes my Foreign Key name.
Of course, this is not how I want to do things, so I am hoping for a bug fix someday.

Dan

How to upload a document with values related to document properties in to document set at same time using Javascript object model

Hi,
Problem Description: Need to upload a document with values related to document properties using custom form in to document set using JavaScript Object Model.
Kindly let me know any solutions.
Thanks
Razvi444

The following code shows how to use REST/Ajax to upload a document to a document set.
function uploadToDocumentSet(filename, content) {
appweburl = decodeURIComponent(getQueryStringParameter('SPAppWebUrl'));
hostweburl = decodeURIComponent(getQueryStringParameter('SPHostUrl'));
var restSource = appweburl +
"/_api/SP.AppContextSite(@target)/web/GetFolderByServerRelativeUrl('/restdocuments/testds')/files/add(url='" + filename + "',overwrite=true)?@target='" + hostweburl + "'";
var dfd = $.Deferred();
$.ajax(
'url': restSource,
'method': 'POST',
'data': content,
processData: false,
timeout:1000000,
'headers': {
'accept': 'application/json;odata=verbose',
'X-RequestDigest': $('#__REQUESTDIGEST').val(),
"content-length": content.byteLength
'success': function (data) {
var d = data;
dfd.resolve(d);
'error': function (err,textStatus,errorThrown) {
dfd.reject(err);
return dfd;
Then when this code returns you can use the following to update the metadata of the new document.
function updateMetadataNoVersion(fileUrl) {
appweburl = decodeURIComponent(getQueryStringParameter('SPAppWebUrl'));
hostweburl = decodeURIComponent(getQueryStringParameter('SPHostUrl'));
var restSource = appweburl +
"/_api/SP.AppContextSite(@target)/web/GetFolderByServerRelativeUrl('/restdocuments/testds')/files/getbyurl(url='" + fileUrl + "')/listitemallfields/validateupdatelistitem?@target='" + hostweburl + "'";
var dfd = $.Deferred();
$.ajax(
'url': restSource,
'method': 'POST',
'data': JSON.stringify({
'formValues': [
'__metadata': { 'type': 'SP.ListItemFormUpdateValue' },
'FieldName': 'Title',
'FieldValue': 'My Title2'
'bNewDocumentUpdate': true,

DataModeler: Cannot engineer from logical model to relational model

Hello,
I have been trying for a couple of (very frustrating) hours to engineer a very simple logical model to its relational model. The toolbar button (and also menu option) that should do this just does nothing. No errors, no feedback, absolutely nothing!!! However I could engineer a relational model back to its logical model.
I am using SQL Modeler version 1.5.1 build 525 on Windows Vista. I have closed and restarted the program many times but to no avail. Are there other factors (e.g. anti-virus, JDK etc) that could be responsible? But then why are other parts of the software working but not this one?
Please kindly send your advice asap so I can proceed. I really like the Modeler and will not want to discard it.
Thanks,
Chiedu

Hi Folks,
I was able to figure out the likely cause of the problem. The version of Modeler (datamodeling-1.5.1-525-no-jre.zip) I used was downloaded without JRE. The current version of JRE installed on my computer is Java 6 Update 12 (build 1.6.0_12-b04). I suppose the two don't quite work very well together.
I have now downloaded and installed another version (datamodeling-1.5.1-525.zip) with its own JRE and the problem was resolved.
My guess is that the problem was due to the incompatibilities that may exist between Data Modeler and the various versions of JRE.
Thanks.

Engineer to Relational Model: deleted attributes / undeleted columns

Hello,
I am using Datamodeler 3.3.0.744.
I'm modifying an existing logical model: I'm deleting one or more attributes in an Entity.
Then I'm executing "Engineer to Relational Model" in oder to get an up to date Relational Model (it existed already).
The corresponding columns are not deleted in the Relational Model, even though attributes don't exist anymore at the logical level.
I can't find any option available in order to do that...
In the previous release (3.1), it worked fine, I could choose the behavior related to the deleted attributes (deleting or not deleting corresponding columns).
Edited by: user4995029 on 27 mai 2013 02:43

When your forward engineer for a 2nd time you should see a dialog that has the logical on the left and the relational on the right. Entities that are new or changes have an exclamation point next to them. If you open that you will eventually drill down to see the attribute/columns. Where your dropped an attribute it will say "To drop". The check box is unchecked by default. If you check it then when you forward engineer those should get dropped from the associated table.
Is it not working that way in 3.3?

SQL Developer Data Modeler Information Flow descriptions

Hello
I am new to SQL Developer Data Modeler. Is there a way to display on the Data Flow Diagram the descriptions on the Information Flow lines.
Regards
Ade

1) Is there a cross reference report so that I can check my information structures on the DFD diagram with the attributes defined at Logical Model diagram?you can use "File>Export>To Reporting Schema" functionality to export your design into Oracle database. Two tables there give usage of attributes/entities in processes - DMRS_PROCESS_ATTRIBUTES and DMRS_PROCESS_ENTITIES. look for "reports\Reporting Schema diagrams" directory under installation of Data Modeler - there are PDF files with diagrams of reporting schema tables.
2) How can I create a copy (synonym) for any of my information stores or external agents on the same DFD diagramgraphical synonyms are supported only for objects in Logical and Relational models.

Synchronizing Column Comments from Relational Model to Data Dictionary?

I've changed/added column comments to a table in my Relational Model. When I try to sync the changes to the Data Dictionary of the Database the new/changed column comments are never included. I can actually see that the values in the Field "Comment in RDBMS" are different in the Compare Models Preview Window but the line is not highlighted in red as I expect, in fact it is even grayed out. I also can't check the corresponding checkbox "selected".
Is there a way to get the comments to synchronize? Do I miss any option I have to set first? Ist this a bug or expected behaviour?
I'm using version 4.0.3 x64 of Data Modeler.
Any help would be much appreciated,
Charlie

Hi Charlie,
The greying out of the "Comment in RDBMS" property would suggest that you have filtered out this property for Column objects in a previous Compare.
To unset the filtering, repeat the sync, and when it displays the Compare Models dialog, select the Options tab and then the Properties Filter tab below it.
Select "Columns" in the left pane, and then find the entry for the "Comment in RDBMS" property in the right pane. The "Included" check box should be set.
You can then select the Refresh Trees button below these two panes.
If you then go back to the Details tab, any differences in the "Comment in RDBMS" property for Columns should now be highlighted in red.

Questions related SQL Developer Data Modeling

1) Is it possible to import ERwin 3.5.2 version(called as Platinum Erwin) erx file to SQl developer data
modeling tool?
2) When this tool going to be released as a standalone Product?
3) One of our requirements is calculating Table and Database size from Data model tool(as a volumetric
report). Is it possible in this tool?. Also i couldn't able to define storage properties(like Tablespace).

I have also replied to you in the feedback application where you logged your query. I have added my response here for others who may be interested.
1)We currently only support import from ERwin 4.x
2) It is company policy not to disclose release dates. We plant to release in 2009.
3) You can define Tablespace using the Physical model. Expand the Relational node and then the physical model. The two nodes you can use for your tablespaces are the Tablespaces and Segment Templates nodes.

Data Model: Relational Tables/Columns Naming Options

Hello,
My design consists of several Relational models.
1. Using Logical model properties, I defined Naming Options (Max. Name Length, Character Case, Valid Characters) applicable to all Entities, Attributes and Views.
2. But for Relational models, Tables/Columns/Views Naming Options (Max. Name Length, Character Case, Valid Characters) can only be defined per Relational model and not for all the models.
Question: Is it possible to define Tables/Columns/Views Naming Options (Max. Name Length, Character Case, Valid Characters) applicable to all Relational models? If yes, please inform me.
Thanks
Chiedu

Andrey,
When You select all the columns, you need to hold the Shift key to select all. Don't let it go to do the copy. So, still holding the shift key, right click for the context menu. The menu only has 2 items, Copy and Delete. Now Copy. Then you can go to the diagram and select paste, to paste them in each of the tables you want those columns to appear in.

It's adding same column to relational model over and over

I'm using 3.3.0.747 now, and I'm pretty sure that it wasn't doing this when I was using 3.1.4. I go into the logical model and add an attribute (say "My notes") to an existing entity (say "Specifications"), adding a preferred abbreviation of "notes" to it. I engineer to the logical model, and it dutifully says that it's going to add a column to the corresponding table ("specs"). And it does.
Now, later, I add some attributes to some other table. When I do the engineering, it says that "notes" doesn't exist in "specs" and it's going to add it. If I let the engineering go through, I find that the relational model for "specs" now has two columns on it, "notes" and "notes1". If I do it again, I get "notes2". If I delete "notes1" and "notes2" and engineer again, "notes1" comes back.
I'm not finding that it does it this every time, but it's doing it for maybe half the columns I add to existing tables. (I haven't figured out a pattern.) If it happens to be a foreign key relationship, it creates an additional foreign key.
So far I've just added a step to my process to hunt down the new columns and delete them (or flag the logical model to not engineer the table at all if I know I haven't changed anything), but there must be something obvious I'm missing..
Edited by: dbomp on Apr 17, 2013 10:53 AM
I'll take back one thing I said: If the once-new column is related to a foreign key, it does keep re-creating the column, but it doesn't create new foreign key relationships to go with it.

I figured it out so I thought I'd put this here in case others bump into it.
What's going on is that the logical-to-relational engineering comparison tool doesn't recognize relational columns that the engineering tool didn't create. Sometimes I would add columns to both the logical and relational models manually rather than engineering. Say all I wanted to do was to add an active_flag to a table. I'd add it to the relational model and then add it to the logical model's corresponding entity with exactly the same values. Later, when I had a bunch of logical model changes to engineer, it wouldn't recognize the active_flag ("preferred abbreviation") in the entity as being the same thing as the active_flag in the relational table, and it'd create an active_flag2 column.
Lesson: only create new relational table columns by engineering them from the logical model.

Bug in SQL Developer relating to handling of XMLTYPE columns

Hi,
I have found a bug in SQL Developer relating to its handling of XMLTYPE columns.
Given a table with the following data:
ID, XML_DATA
1, <xml here>
2, <xml here>
3, <xml here>
And the following SQL to extract a value from the XML and also an XML fragment as an XMLTYPE:
SELECT
EXTRACTVALUE(t.column_value,'/*/USER_ID/text()')user_id
, t.column_value user_data
FROM dbuser.mytable m
, TABLE(XMLSEQUENCE(EXTRACT(m.xml_data, '/*/USER_LIST/USER'))) t
I get the following:
user_id, user_data
jsmith26, (XMLTYPE)
mjones45, (XMLTYPE)
sborga31, (XMLTYPE)
Note that the user_id is correctly extracted, however the XMLTYPE column (user_data) is empty in SQL Developer.
The same query returns the correct XML data in TOAD.

Steve,
So your example is slightly more complex than the one documented for a table in the standard OE schema here:
http://docs.oracle.com/cd/B19306_01/server.102/b14200/functions052.htm
That example works fine on an 11.2.0.1 database with SQL Developer 3.2.20.09.87. Please try the following with your case:
Tools -> Preferences -> Database -> Advanced -> Display Struct Value In Grid (check it off if not already)If that still does not work for Run Statement (query result displayed in the grid, not as script output using Run Script), then please provide a test case based on the Warehouse table in the OE schema (or your case with DDL and DML scripts including the xml data) and I will log a bug.
Thanks,
Gary
