External table to relational model
Hi,
During a data dictionary import, tables, views, mat views and sequences are "propagated" up to the relational model level, but external tables do not. I think it would be useful if external tables could also be "brought up" to the relational level since an external table is only a different kind of physical structure.
Regards,
Gellért
I am seconding the request to be able to use External tables in the same manner that tables can be used within the Data Modeler. they can be imported into the Physical model, but not in the relational models.

Sharing tables between relational models
Can I share (not copy) table between two relational models in SQL Developer Data Modeler? Something like sharing tables between application systems in Oracle Designer. I have one database schema for reusable kernel of many applications and I want to have one relational model for it. And I need to use tables from kertnel in other applications (database schemas). I need for example to make FK between application and kernel table. How can I do it?
Hi,
you can use drag&drop from browser to diagram of target model in order to do that. Table becomes read-only in target model. You can use "Synchronize remote objects" to get actual status of such "remote" table

Data Modeler - applying naming standards to relational model
Hi,
first of all thanks for the new data modeler build (584) - it really fixed some issues (e.g. unique keys with non mandatory referenced ids are now persistent) ...
BUT ... why is there an option to disable foreign key names when applying naming rule although it does not work?
I like my primary key names etc. to follow some naming rules, but I don't like foreign keys to follow rules, just because neither "Benutzer_Id3" follows the company internal naming rules nor is it very easy to understand at all.
Steps taken:
* logical model is complete
* generate relational model
* foreign key names are as intended (e.g. "User_Id_Modifier")
* right click the relational model
* click "Apply Naming Standards ..."
* remove the check mark from "Column Foreign Key"
* click "OK"
The foreign key column is changed regardless of checkbox state :-( - even deselecting all check boxes still applies naming rules to the foreign key columns.
Is there a fix/workaround for that or need I to go back to build 570?
Thanks god I still have my 570 compatible model ins SVN
regards stuecklHi,
unfortunately that functionality for all tables in relational model is broken - you still can use it at table level - "Naming rules" button in table dialog.

Create multiple external tables from same flat file ?
using oracle 10g
currently create many external tables like so..
CREATE TABLE "XT_UNITS"
"Q1_2012" VARCHAR2(25 BYTE),
"Q2_2012" VARCHAR2(25 BYTE),
"Q3_2012" VARCHAR2(25 BYTE),

skip 1 fields terminated BY ',' OPTIONALLY ENCLOSED BY '"' MISSING FIELD VALUES
ARE NULL ) LOCATION ( 'xtunits.csv' ))
is there any way I can use 1 flat file (csv) to populate many external tables ?
maybe by section ?Jay wrote:

An external table definition relates to one or more files.
You could probably create multiple externable table definitions to access the same file(s), but you may end up with some operating system file locking issues if you're not careful, and to be honest why would you need to do that? -
how can i import tables from a different schema into the existing relational model... to add these tables in the existing relational/logical model? plss help
note; I already have the relational/logical model ready from one schema... and I need to add few more tables to this relational/logical model
can I import the same way as I did previously??
but even if I do the same how can I add it in the model?? as the logical model has already been engineered..
please help ...
thanksHi,
Before you start, you should probably take a backup copy of your design (the .dmd file and associated folder), in case the update does not work out as you had hoped.
You need to use Import > Data Dictionary again, to start the Data Dictionary Import Wizard.
In step 1 use a suitable database connection that can access the relevant table definitions.
In step 2 select the schema (or schemas) to import. The "Import to" field in the lower left part of the main panel allows you to select which existing Relational Model to import into (or to specify that a new Relational Model is to be created).
In step 3 select the tables to import. (Note that if there are an Foreign Key constraints between the new tables and any tables you had previously imported, you should also include the previous tables, otherwise the Foreign Key constraints will not be imported.)
After the import itself has completed, the "Compare Models" dialog is displayed. This shows the differences between the model being imported and the previous state of the model, and allows you to select which changes are to be applied.
Just selecting the Merge button should apply all the additions and changes in the new import.
Having updated your Relational Model, you can then update your Logical Model. To do this you repeat the "Engineer to Logical Model". This displays the "Engineer to Logical Model" dialog, which shows the changes which will be applied to the Logical Model, and allows you to select which changes are to be applied.
Just selecting the Engineer button should apply all the additions and changes.
I hope this helps you achieve what you want.

How to find the level of each child table in a relational model?
Earthlings,
I need your help and I know that, 'yes, we can change'. Change this thread to a answered question.
So: How to find the level of each child table in a relational model?
I have a relacional database (9.2), all right?!
O /* This is a child who makes N references to each of the follow N parent tables (here: three), and so on. */
/↑\ Fks
O"O O" <-- level 2 for first table (circle)
/↑\ Fks
"o"o"o" <-- level 1 for middle table (circle)
↑ Fk
"º"Tips:
- each circle represents a table;
- red tables no have foreign key
- the table in first line of tree, for example, has level 3, but when 3 becomes N? How much is N? This's the question.
I started thinking about the following:
First I have to know how to take the children:
select distinct child.table_name child
from all_cons_columns father
join all_cons_columns child
using (owner, position)
join (select child.owner,
child.constraint_name fk,
child.table_name child,
child.r_constraint_name pk,
father.table_name father
from all_constraints father, all_constraints child
where child.r_owner = father.owner
and child.r_constraint_name = father.constraint_name
and father.constraint_type in ('P', 'U')
and child.constraint_type = 'R'
and child.owner = 'OWNER') aux
using (owner)
where child.constraint_name = aux.fk
and child.table_name = aux.child
and father.constraint_name = aux.pk
and father.table_name = aux.father;Thinking...
Let's Share!
My thanks in advance,
Philips

Understood.
Nocycle not work in 9.2 and, even that would work, would not be appropriate.
With your help, I decided a much simpler way (but there is still a small problem, <font color=red>IN RED</font>):

Table properties doesn't propagate from Relational Model to physical model
Hi all,
I have a relationnal model with several tables and several schema.
When i create a new table in the relational model with a specified schema, the table is created on the physicla model, but the schema is not prapagate.
Is there a way to do this automatically ?
Or do i have to specify the schema on the relationnal and on the physical.
Thank youHi,
schema object in relational model needs to be implemented in physical model - user is the implementation of schema in Oracle physical model. User has property "implements schema". You also can omit this redirection and can assign directly user to table but in this case you'll lose the flexibility.
Here is how DDL is impacted using different option (schema_1 and table_1 in relational model):
1) physical model is not open - no implementation details
CREATE TABLE Schema_1.TABLE_1
Column_1 NUMBER
;2) physical model is open - Schema_1 is not implemented
CREATE TABLE TABLE_1
Column_1 NUMBER
) LOGGING
;3) physical model is open - Schema_1 is implemented by User1
CREATE TABLE User1.TABLE_1
Column_1 NUMBER
) LOGGING
;4) physical model is open - Schema_1 is implemented by User1; Table_1 is directly assigned to User2 in physical model
CREATE TABLE User2.TABLE_1
Column_1 NUMBER
) LOGGING

External Table - possible bug related to record size and total bytes in fil
I have an External Table defined with fixed record size, using Oracle 10.2.0.2.0 on HP/UX. At 279 byte records (1 or more fields, doesn't seem to matter), it can read almost 5M bytes in the file (17,421 records to be exact). At 280 byte records, it can not, but blows up with "partial record at end of file" - which is nonsense. It can read up to 3744 records, just below 1,048,320 bytes (1M bytes). 1 record over that, it blows up.
Now, If I add READSIZE and set it to 1.5M, then it works. I found this extends further, for instance 280 recsize with READSIZE 1.5M will work for a while but blows up on 39M bytes in the file (I didn't bother figuring exactly where it stops working in this case). Increasing READSIZE to 5M works again, for 78M bytes in file. But change the definition to have 560 byte records and it blows up. Decrease the file size to 39M bytes and it still won't work with 560 byte records.
Anyone have any explanation for this behavior? The docs say READSIZE is the read buffer, but only mentions that it is important to the largest record that can be processed - mine are only 280/560 bytes. My table definition is practically taken right out of the example in the docs for fixed length records (change the fields, sizes, names and it is identical - all clauses the same).
We are going to be using these external tables a lot, and need them to be reliable, so increasing READSIZE to the largest value I can doesn't make me comfortable, since I can't be sure in production how large an input file may become.
Should I report this as a bug to Oracle, or am I missing something?
Thanks,

Query related to external table authentication

At this point, can we authentication the userid and password which is stored in external table in a users schema?

Join large external external Tables (best practice ?)
Hi there,
I have three external tables in a master-detail relation: table A (10000000 rows) is master of table B (20000000 rows), Table B is master of table C (100000000 rows). Can you tell my the best way:
- directly join the external tables, or
- copy the external tables into tables, create an index, and join them
What is more efficient, and why ?
Thanks for your help and ideas.
Gerhard.In general, if the joins you are doing can benefit from indexes, you will want to copy the data to database tables. If the joins will end up doing full table scans anyway, it will matter far less.
For data integrity, you will likely also want to be able to enforce foreign key constraints.

DATE fields and LOG files in context with external tables
I am facing two problems when dealing with the external tables feature in Oracle 9i.
I created an External Table with some fileds with the DATE data type . There were no issues during the creation part. But when i query the table, the DATE fields are not properly selected though the data is there in the files. Is there any ideas to deal with this ?
My next question is regarding the log files. The contents in the log file seems to be growing when querying the external tables. Is there a way to control this behaviour?
Suggestions / Advices on the above two issues are welcome.
Thanks
LakshminarayananHi
If you have date datatypes than:
select
greatest(TABCASER1.CASERRECIEVEDDATE, EVCASERS.FINALEVDATES, EVCASERS.PUBLICATIONDATE, EVCASERS.PUBLICATIONDATE, TABCASER.COMPAREACCEPDATE)
from TABCASER, TABCASER1, EVCASERS
where ...-- join and other conditions
1. greatest is good enough
2. to_date creates date dataype from string with the format of format string ('mm/dd/yyyy')
3. decode(a, b, c, d) is a function: if a = b than return c else d. NULL means that there is no data in the cell of the table.
6. to format the date for display use to_char function with format modell as in the to_date function.

===========================
In the error it is showing that file expense_categories.csv in SOURCE_LOCATION not found but I am 100% sure that file is very much there.
Is anybody face the same issue?
Do we need to configure something before loading data from a flat file from OWB Client?
Any help would higly appreciable.
Regards,
Manmohan SharmaHi Detlef / Gowtham,
Now I am able to fetch data from flat files from OWB Server as well as OWB Client.
One way I have achieved as suggested by you
1) Creating location on the OWB Client
2) Samples the files at client
3) Created & Configured external table
4) Copy all flat files on OWB Server
5) Updated the location which I created at the client.
Other way
1) Creating location on the OWB Client
2) Samples the files at client
3) Created & Configured external table
4) Copied flat files on the sever in same drive & directory . like if my all flat files are on C:\data at OWB Client then I copied flat file C:\data on the OWB Server. But this is feasible for Non-Windows.
Hence my problem solved.
Thanks a lot.

Error while reading data through External Table!!!

External table creation went through successfully but am getting error while reading data. Am quite sure error is because of above line in red color. Could you please help me in transforming logic.
Thanks in Advance,
APLet's start with the basics...
1) You state that you are getting an error. What error do you get? Is this an Oracle error (i.e. ORA-xxxxx)? If so, please include the error number and the error message as well as the triggering statement. Or is the problem that rows are getting written to the reject file and errors are being written to the log file? If so, what record(s) are being rejected and what are the reasons given in the log file? Or perhaps the problem is something else?
2) You state that you are quite sure that the problem relates to the hilighted code. What makes you quite sure of this?

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 ErikErik,
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
