SQL DM - Copy/Export data models - bug?

SQL DM - Copy/Export data models - bug?
I am using SQL DM 3.0.0.665. I need your thoughts on following.
We used saved as/export of the SQL DM copy the model into another location. We kept our models in harddrive as folder. We did not store it in database.
We opened the copied model from target model. We found all the links to defined domain was lost. We find the data type shows as Varchar2 instead of Varchar2(20)etc. It creates error on sql.
Why are loosing the domain definition/linkages during export/save as option?
Is it a bug?
Did anyone face such issues?
What is the workaround?
Thanks in helping us out.

Hello,
Thanks for your reply. I followed the steps. I did copy the folders/files as Kent suggested.
As we installed the SQL developer on new desktop, it showed the domain definitions as unknown and count as 1 in Design Tree --> domain node. We copied all the xml files under C:\datamodeler\datamodeler\types folder of Desktop A to Desktop B. It brought all the domain definitions of Design in Desktop A.
Why does it not keeping this domain definitions as part of Design folders?
If we copy or save as the design , then domain also cane be saved as part of design. It will be difficult to make a sync of datamodels among multiple desktops.
How do we establish a shareable/sync data models using SQL data Modeler on such situations?
Thanks in helping.

SQL Data Modeler bugs (or only misused?)

Hi,
I think I ran into some modeler bugs and missing features ...
BTW: is there a place where all the known bugs are listed?
* although "no action" was selected in "General Options - Model - Relational" for foreign keys all the foreign keys are created with
"not deferrable" (well, why not, if it makes the modeler happy) and
"on delete set null" (thats not what I'd call "no action")
* DDL statements for indexes lack the schema name
* newly generated foreign relations are not always displayed in the relational model
* DDL preview for syncing physical model with relational does not (always) work (well - so far it worked once)
steps taken: File - Import - Data dictionary, selected objects for import, correct target model chosen, "swap target model" checked
* foreign keys in unique constraints are always set to "not null" (in logical and physical model)
* no trigger/constraint created for ARCs (I am not sure about this, but IIRC I did not see anything making an ARC really work)
Or do ARCs simply not work yet?
* modeler hangs sometimes (e.g. when opening "Save as" dialog etc.)
* dialogs are opened outside visible pane when the position of monitors is changed (the dialogs seem to remember their last position)
* sequences (physical model withing relational model) are loosing their user
* missing multi schema capabilities :-(
* the layout capabilities - pardon my french - suck
Especially that the boxes and lines seem to wander around from one usage to the next (entities aligned with grid - next start the entities are no longer aligned).
And if you ever need to save/export the model somewhere else all the references stick to a single connection point.
Not to mention a simple move of a box ...
Thank you for your effort

Hi Philip,
sorry for not answering quite a time ...
Just some prerequisites ;-) ...
- Target database: Oracle 10g R2 (10.2.0.4)
- Modeler version 2.0.0 build 570
- model creation method: logical model, relational model, (physical model), Database objects
- OS WindowsXP German, SP3
- JDK Sun Java 1.6, build 1.6.0_16-b01
* nullable FK column in unique keys
meanwhile I found out, how to achieve that - but IMHO the steps to take are quite cumbersome
1) make a FK relation with "target optional" checked on the Cardinality page of the FK properties
2) open entity properties, check attributes of FK column (it says: nulls allowed - the checkbox cannot be changed)
3) got to unique identifiers page and add a unique identifier
4) open the unique identifier property dialog and add the foreign key
5) close both property dialogs
6) reopen the entity property dialog, check attributes of FK column (it says: no nulls allowed - the checkbox cannot be changed)
7) check the FK properties: it still says: target optional (it is checked)
8) check the graphical representation of the FK key: dashed line at target entity (meaning: optional)
9) create the relational model: the FK column is created with "not null"
10) go back to logical model
11) change FK property to: target mandatory (uncheck "target optional")
12) create relational model
13) change FK property to: target optional (check "target optional")
14) create relational model
15) SUCCESS! the foreign key column is now nullable
BUT: you never ever must change ANY of the entities properties or you must redo steps 11 to 15
* "no action" of FKs
I will look into that. Thanks for the suggestions.
* DDL statements for indexes
Sorry for being imprecise ... I was talking about automatically generated indexes (for unique and foreign keys).
Those don't show up in the index listing of the tables in the physical model (probably, because they are automated).
But why do I have to set the default schema for indexes again? The tables get the schema information for the default schema (General Options - Model - Physical) but not the indexes :-(.
Generated DDL snippet:
CREATE TABLE ZCBC1ST1.ZCBRAGIT_AGENDAITEM ( ...
CREATE UNIQUE INDEX ZCBSAgIt_U1X ON ZCBC1ST1.ZCBRAGIT_AGENDAITEM ( ...
Same for FK indexes. And the unique index property page in the physical table section does not let me specify a schema owner (OK for me, because the unique key is created by an "alter table" statement).
* ARC trigger
My bad - I only checked "DDL preview" of the table, which doesn't show the ARC trigger. The complete generation does. Sorry.
* "missing multi schema capabilities" and "sequences loose owner"
Please excuse a newbie blush.
I just found out I can change the table owner using the physical model capabilities (I guessed I used way too long PowerDesigner V6 ;-) ).
BUT ...
The newly created user does not "survive" a "save all - close all - open" sequence on "Physical Models" ... only closing the app or saving the Oracle10g physical model makes the user persistent.
And also ... if the new table or sequence owner is the first in the drop down list on the property dialog, the user is replaced by an automatically created new user (e.g. User4, User5, and so on).
Example:
* I have three defined users and the standard "MDSys" and "Public".
* My three users are named ZCBC1ST1, ZCBCCore and ZCBCDial (those names are because i need to follow naming rules).
* ZCBC1ST1 is my default physical model user, which was set in "General Options"
* ZCBC1ST1 is the first in each drop down list.
* I have some sequences named Seq1, Seq2, Seq3 and Seq4
* Seq1 was given to ZCBC1ST1, Seq2 to MDSys, Seq3 to ZCBCCore and Seq4 to ZCBCDial
* saved and closed the Oracle10g physical model and reopened it
* Seq1 now has User4, but the other have still the users they were attached to
The same applies to tables - I am unable to give a table to the first entry of the user list.
Solution I found to this problem ...
1) remove the default physical user in "General Options" (and never ever set it again)
2) create a explicit user (with the name of the prior default user)
3) manually reattach all objects to this user sigh
4) so far not a problem with automatically generated indexes, because they don't use the default user anyway
* newly generated FKs not shown in relational model
I had this odd behaviour several times.
1) Logical model: adding a new FK relation
2) giving the reference-column a pretty relational name
3) generating the relational model
4) rather often the new column shows up in the relational model but the arrow for the new foreign key does not.
5) only after i open the properties dialog of the missing foreign key the arrow is shown in the model
6) happens often to sub-models - less often to the top-model
* model syncing (Oracle10g with modeler)
As Ms. Harper stated in one of her posts (and she even made a video tutorial IIRC) it should be possible to sync a Modeler model with the Oracle10g contents.
AFAIR the tutorial showed only how to sync the model with the contents but not vice versa.
I tried to achieve this checking the "swap target model" check box (that's the important thingy) of the import dialog. Everything worked fine besides there is only a preview of DDL statements available but no "Merge" or "Create DDL Statement". And exactly that preview doesn't seem to work anymore. No matter what objects I select, I am unable to see any DDL statements to upgrade the Database.
I don't know why, but it worked again just before. I will keep an eye on this. ;-)
So much for now ...
Thank you for your effort

RegardsCan't you save the Report1 as Report2 (by doing this you will have your Data Model and everything from Report1 will be copied to Report2) and do those little modifications in the Report2.
OR
Take the SQL statement from the Report1 and use that in the Report2.

SQL Developer 3.0 data modeler print-to-pdf not working

I am working in Windows XP. I am running SQL Developer version 3.0.04, which now includes a full-featured version of the Data Modeler. I have run into a problem with this version, which did not occur in the stand-alone version of the Data Modeler.
When I try to print a data model diagram [File -> Data Modeler -> Print Diagram -> To PDF file], a PDF file is generated. When I try to open that PDF file with Adobe Reader (version 9.4.3) I get the following error message:
"Adobe Reader could not open 'finename.pdf' because it is either not a supported file type or because the file has been damaged(for example it was sent as an email attachment and wasn't correctly decoded)."
Furthermore, the size of the file in question is 0 bytes. When I use the same process in the stand-alone version, a readable PDF file is created whose size is 858 bytes.
The 'print to IMAGE file' option works well in both versions.
Any help resolving this would be appreciated.

I am having almost same problem. PDF file is genereted about 400K but blank.

Data Modeler bug? - it keeps reporting missing physical model files

Hi,
I'm having a rather serious problem with the latest data modeler, Oracle SQL Developer Data Modeler 3.1.4.710. It keeps losing physical model files for some reason.
I started to notice that it was not generating all the tables in my small design. After hours of struggle I found multiple error messages in the log file:
2012-12-18 10:51:20,126 [Thread-71] ERROR XMLTransformationManager - Unable to load object from XML: C:\cygwin\home\Brian\codebase\models\data\Design\rel\395D160B-C7224B8EAD05\phys\D9582E4E-2ED963CB9D32\View\seg_0\A555DB9B-8864-9C0B-DCA8-BAC5231F55C6.xml

These messages appeared every time I opened my physical model (Oracle 10g).
After deleting and recreating the physical model the problem went away for a while. But after closing and reopening the design I started to see the errors again.
Has anyone seen something similar?
Regards,
Brian

Thanks Philip!
The workaround does the trick for the tables, primary keys and unique keys.
I have just observed that table level constraints show a slightly different behaviour.
Names show up like TCC5, TCC6, etc.
Seems the same problem as previously in SQL*Modeler forgets check constraint names
Is there a workaround for that problem too ?
I already noticed that there is no parameter NameChanged for a table constraint.

Data Modeler 2.0.0 Windows Authentication to SQL Server

Is there a way to sign onto a SQL Server database with Data Modeler similar to SQL Developer using Windows Authentication? I have loaded the correct JDBC drivers.

It wasn't possible for me (Win XP) but you can try using following steps:
1) get JDBC driver from Microsoft site - http://msdn.microsoft.com/en-gb/data/aa937724.aspx - you can use 1.2 or 2.0
2) copy sqljdbc_auth.dll to windows\system32 directory as described here http://msdn.microsoft.com/en-us/library/ms378428.aspx
3) add JDBC driver as third party driver in General options (Data Modeler)
4) add ;integratedSecurity=true to port information (or database) - my port looks "1779;integratedSecurity=true"
It doesn't work due strange incompatibility between the way we use connections and JDBC driver implementation related to usage of sqljdbc_auth.dll - may be it will work for you :). We have it fixed and fix will be included in next patch release.

How to see data modeller reports in sql developer?

How to see data modeller reports in sql developer?

1) export your design to existing schema in Oracle database
2) define connection to that schema in SQL Developer
3) find "Data Modeler Reports" in reports window of SQL Developer - probably "design rules" are more interesting here

SQL DEVELOPER 1.5.3: Export Data options for using SQL to write SQL?

I write a lot of SQL that generates SQL. In a competitor's product, I can export query results (Export > Save As > Tab Delimited) to the clipboard, paste the generated SQL into a new window, then execute the generated SQL.
In SQL Developer, using Export Data > Text to the clipboard, it's delimiting each row with double-quotes. Is there any way to turn this behavior off to achieve what I want? Or should I be choosing a different export format?
For now, I can do a search/replace to eliminate the double-quotes,
Thanks.
Dana

Dana,
I probably haven't done this with generating thousands of SQL lines, but I have certainly used the Ctrl-A, Ctrl-C (or Ctrl-Shift-C to get headers) to copy thousands of records of result data. Note that the Ctrl-A forces a fetch of all remaining records that have not yet been fetched, which may add to the time taken by the process - for example, running the query fetches the first 50 records and then Ctrl-A will fetch the remaining records as well as selecting them all, however long that takes. Also, there is a noticeable delay with the Ctrl-C for thousands of records - only rough counting but I was seeing a UI freeze for ~ 4 seconds when copying 10000 records from a query with around 30 columns in it (pasting the clipboard into a file produced a file just under 4MB).

Copy data models and reports from BW 3.1 to NW 2004s

Hi experts,
Our client has two BW servers: BW 3.1 and BI 7. BW 3.1 contains lots of data models and reports. And the BI 7 server is newly installed.
Now we want to copy these data models and reports from BW 3.1 to the new BI 7 server. Are there any solutions for this?
Thank you very much in advance.

Hi Frank,
Sounds like a cross version transport is needed.
This is a solution we have used to do what you want to do:-
Create and release a transport as per normal.
Copy and transport the files from the source system (BW 3.1) e.g /usr/sap/trans/data & /usr/sap/trans/cofiles to the same folders on the target system.
Basis help is needed here.
From here onwards using stms_import should help you in the normal manner.
Works a treat.
Have transported the following all correctly appearing as 3.x data models in NW2004s.
DSO objects.
Cubes
Transfer/Update rules
Reports.
Cheers,
Pom

OBIEE EXECUTE PHYSICAL sql as Data Model Query

The following SQL was generated using OBIEE. I'd like to use it as the SQL query for my data model. It works fine it I hard code all of the values into the where clase. However when I attempt to pass parameter values (:ACCOUNTING_PERIOD & :FISCAL_YEAR) into the below SQL statement, I get an error and the report will not generate. The error is the typical "The report can't be rendered. Check with your administrator". Any ideas on how I can pass parameter values into this SQL?
EXECUTE PHYSICAL CONNECTION POOL SDEVDW SELECT A.BUSINESS_UNIT,A.PROJECT_ID,A.PROJECT_STATUS,A.EFFDT FROM SPSDW.PS_PROJECT_STATUS A WHERE A.EFFDT = (SELECT MAX(B.EFFDT) FROM SPSDW.PS_PROJECT_STATUS B WHERE B.BUSINESS_UNIT = A.BUSINESS_UNIT AND B.PROJECT_ID = A.PROJECT_ID AND B.PROJECT_STATUS<>'C' AND B.EFFDT <= (SELECT PPERIOD_END_DT FROM SPSDW.PS_D_DET_PERIOD WHERE PPERIOD_CD = 6 AND PYEAR_NUM = 2008 AND DT_PATTERN_CD = '01' AND SRC_SYS_ID = 'FSCM')
) ORDER BY 1,2,3

I turned on debug and bounded OC4J. After I ran the report, I did not see any link.
The error that returns is:
"The report cannot be rendered because of an error, please contact the administrator."
Where will the link be located. Is there are log file that I can review. We are using BI Publisher enterprise (10.1.3.3.0).

SQL Query Data Model Question

Hi All,
I'm new to XMLPublisher so i'll try to explain the best i can the problem i'm having creating a Data Model for my report.
I'm using Database XE and have installed XMLPublisher, as XE is extremely flexible in creating apps i'm having huge trouble finding a reporting solution for my applicaiton. I have created an app to track and control time and expense which i want to generate timesheet, expense sheets, invoice etc from.
Having done some read i think XML is the best approach for me however i'm having huge troubles with my data model.
EXAMPLE:
I have 2 tables to start with, first table holds client information and the second table holds project information. One client can have many projects.
When i create the Data Model using SQL i get the obvious problem that when a client has more then one project my XML structure is incorrect.
SELECT gc.name AS CLIENT,
gp.name AS PROJECT
FROM gte_client gc,
gte_project gp
WHERE gc.client_id = gp.client_id(+)
The above SQL creates the following XML
- <ROWSET>
- <ROW>
<NAME>Symatrix Ltd</NAME>
<NAME>Symatrix Pre-Sales</NAME>
</ROW>
- <ROW>
<NAME>Aston Carter</NAME>
<NAME>MOD</NAME>
</ROW>
- <ROW>
<NAME>Symatrix Ltd</NAME>
<NAME>Fujitsu</NAME>
</ROW>
</ROWSET>
Obvious problem here is the fact that client Symatrix appears twice as there are 2 projects.
I have tried to write SQL/XML and i think i'm beginning to understand the structure of the XML functions however XMLPublisher doesn't appear to understand the syntax when creating a SQL Query for the data model.
I hope all this makes sense.
Kind Regards
Glen

Hi All,
Ok, so with a little searching through documents and articles on the web i found this information.

MySQL functionality within Oracle SQL Developer Data Modeler

Hi all,
I've read a few forum posts here that lead me to believe that MySQL is not currently supported by the data modeler tool (Link #1 I got to by clicking on the Statement Of Direction link on the main page SQL Developer Data Modeler</title><meta name="Title" content="SQL Developer Data Modeler"&g… Link #2 I got to by doing a search on the word MySQL within the forum search):
Link 1:
SQL Developer Data Modeler Statement of Direction
Link 2:
Can datamodeler be used with MySQL?
SQL Developer (not the Data Modeler tool, but the database admin-type tool not for modeling) does support MySQL using the latest MySQL Connector J 5.1 driver but, strangely, it doesn't seem the Data Modeler supports it, though. Can anyone please confirm that MySQL is currently unsupported for the Data Modeler tool? Thanks in advance.

Hi,
it doesn't seem the Data Modeler supports it, though.
Data Modeler doesn't have specific support for MySQL - i.e you cannot generate DDL for MySQL. Though you can import form MySQL server using JDBC connection in standalone DM or using created MySQL connection if you are using DM inside SQL Developer.
You can import definitions for tables(columns, PK and UK constraints, indexes, foreign keys) and views.

SQL Developer 2.1.0.63 - Export Data menu missing for SQL Server databases

Hi
The Export Data menu only appears for Oracle databases in this version, it does not appear for SQL server databases.
To demonstrate:
Press F9 to run query
Right click on Query Result data
For Oracle an Export Data sub menu appears
For SQL server no Export Data sub menu appears
This worked in previous versions.
Is this functionality going to reappear?
Thanks

Hi,
Looks like this is exactly the same problem for third party connections as I have the exact same issue for mySQL.

How to install Data Modeler

Hi,
I downloaded Sqldeveloper data Modeler for Windows 32 bit including JRE. The data modeler has to run on windows 7 64 Bit as well as the sql developer runs
After unzipping this file I tried to start the datamodeler. When I starter the 32 Bit version I got the error:
Cannot be startet becaus MSVCR71.dll is not on the computer.
When I tried to start the 64 Bit version I got the error
Unable to launch the Java Virtual Machine located at path ..\..\jdk\jre\bin\client\jvm.dll
What must I do to install the datamodeler?
Please help me.
Regards
Siegwin

Hi Siegwin,
The download including JRE only includes a 32 bit JRE.
This jre includes a copy of file msvcr71.dll (in folder datamodeler\jdk\jre\bin). However it seems that in some circumstances the system does not find this file.
There have been several message threads about this, both for SQL Developer and for Data Modeler.
For example, from https://forums.oracle.com/forums/thread.jspa?messageID=10624958 it appears that copying msvcr71.dll to the Windows\System32 folder may solve the problem,
or starting Data Modeler using the datamodeler.exe file in folder datamodeler/datamodeler/bin may help. (This brings up an additional command prompt window.)
Message Re: Oracle Data Modeler Installation guide may also be relevant.
To run Data Modeler in 64 bit mode, you will need to provide your own 64 bit JRE.
If you edit the file datamodeler64.conf (in folder datamodeler\datamodeler\bin) and remove the line starting with "Set JavaHome", next time you attempt to start 64-bit Data Modeler it should ask you for the location of the java.exe file in your 64 bit JRE.
There is now a forum specifically for Data Modeler issues: SQL Developer Data Modeler
