Create a view in the database based off a jdbc connection

I have some data in a DB2 database that I would like to union with a table in an Oracle Database in the Oracle Database.
Can I create a jdbc connection in the Oracle database that points to the DB2 database and then create a view based off of the jdbc connection?
I've never done anything like this , but if this a no brainer please just post a link or something that points me in the right direction thanks...
I've searched...

Mark,
I was going to suggest the same thing as Jan did when she answered this question that you also posted to the Union DB2 and Oracle data in a view and display in a form using jdbc? forum.
Good Luck,
Avi.

Include or create a view in the database and use this view?

Well, I need to get related data of the main table from another related tables, so one way to do that is to use the Include method in Entity Framework to get this related data.
However, I am thinking in another option, create a view in the database and use this view in entity framework. In this way, I avoid the needed of the include, because I think that is expensive in resources. But I am no very sure about that.
I would like to know if the use of views on entity framework is a good idea to improve the performace or is better to use the include.
For example, if I use the include I have the advantage that I get only one the main record and all the related data I have in the navigation properties, so the info is more shorted.
Which is the advanteges and disadvantages of both methods to get related data in entity framework?
Thank so much.

Hello ComptonAlvaro,
>>I would like to know if the use of views on entity framework is a good idea to improve the performace or is better to use the include.
If your view would use a Join syntax to query master-child relationship tables, it actually is similar with the Include() method which actually results a duplicate records from master table, you could check this
link for detail description.
>>Which is the advanteges and disadvantages of both methods to get related data in entity framework?
One visible difference is that records from Views are not editable by default(if you want edit them, you could refer to this
blog).
In your case, my suggestion that you could use the lazying load which will load the matter table once and disable the trace if you only need to display data.

Error while creating materialized view which using database link

Helo!
I'm getting error "ORA-00942: table or view does not exist" when I want to create materialized view.
Details:
1. On destination database I create a database link:
CREATE DATABASE LINK SDATABASE
CONNECT TO MYUSER
IDENTIFIED BY MYUSERPASS
USING 'ORCL';
=> Command "SELECT * FROM TABLE1@SDATABASE" returns data normally!
2. On source database I create MATERIALIZED VIEW LOG:
CREATE MATERIALIZED VIEW LOG
ON TABLE1
WITH PRIMARY KEY
INCLUDING NEW VALUES;
3. Now, when I want to create MATERIALIZED VIEW on destination database:
CREATE MATERIALIZED VIEW TABLE1
REFRESH FAST
START WITH SYSDATE
NEXT SYSDATE + 1/1440
WITH PRIMARY KEY
AS SELECT * FROM TABLE1@SDATABASE;
...I get error "ORA-00942: table or view does not exist"!
How is that possible if command "SELECT * FROM TABLE1@SDATABASE" returns data normally?
Thanks,
Voranc

And, I'm using Oracle 10g.

Creating filtered view on the physical layer ussing session variable USER

Hi:
I´m creating a view on the physical layer, the view needs to be created dynamically. So depending on the user (using the session variable USER) the view is created with the data a particular user is able to see.
Fisrt I imported the table and changed it´s properties to be created through a "Select Statement" so i don´t needed to change the mapping on the bussiness model layer.
The consistency check was OK but i´m not able to see data in answers, even using the Administrator user. Have anyone tried to do this? Here is my query.
Thanks
A Garcia
Select * from D_ESTRUCTURA_RH2 where Region_ID
IN
select distinct a.REGION_ID from APP_INDPERSONAL_DM.D_ESTRUCTURA_RH2 a
inner join (
select distinct b.REGION_ID from APP_INDPERSONAL_DM.D_ESTRUCTURA_RH2 b
where exists (select 1 from APP_INDPERSONAL_DM.Autorizacion a, usuarios c
where a.app_id = 1
and a.usuario_id = c.Usuario_Id
and UPPER(c.Nombre_Usuario)=UPPER(':USER')
and a.miembro_id = 'REGION_ID'
and a.operador = '='
and (b.REGION_ID = (case when valor = 'Todo' then 0 else valor end) or valor='Todo'))
) seguridad
on
a. REGION_ID = seguridad.REGION_ID
)

whay not use the same filter in the content tab of the logical table source?
check the physical sql sent to databse using web-admin-manage sessions-view log and see if there is any unexpected behavior. also run the same query in db and see iff you get the results in databse itself.

Turn Autocommit off for JDBC Connection

I'd like to control the commit for DBMS_XMLSave operations on my own instead of auto commit. The documentation says to "Turn Autocommit off for JDBC Connection", but I haven't found how to do that yet, any clues?

My apologies for how complicated this is, it was written to be a
generic xml processor for multiple tables. I narrowed it to one
table. It converts a long to clob, parses it, walks the dom to
find rows and processes each row. One InsertXML per row in the
XML.

Creating the materialized view using the database link

Hi Guys,
I am using the Oracle 11g release version.
Following is my question,
I had created the Database link to get the data from remote DB table.
Using that DB link, i can access the required table using SELECT statment.
When i tried to create the materialized using that DB link.
I am getting the error SQL Error: ORA-00942: table or view does not exist.
Can anyone please find the root cause and provide the solution for this?
TIA,
Dhivakar.

Hi Dhivakar,
try like this
CREATE DATABASE LINK test
CONNECT TO scott IDENTIFIED BY tiger
USING 'orcl';
Pls make sure the table name.which ur using to create the materialized view.Thanks

How to create XMLTYPE View from the XMLType table

Hi:
I have a large XML file and inserted to the XMLTYPE table
For the XQUERY purpose I would like to create XMLView of the table.
The examples I got from Oracle to create XML view are for small files.
Can some one help me how to create XMLType VIEW for large XML Files ( 20,000 lines )?

Have a look at the examples given on XMLType Views (based on relational tables) or standard views (based on XMLType storage) in the FAQ url located on the main page of this forum site regarding XMLDB.

How to view definition of a view in the database

Hi !
I want to see the definition of a view that has already been created in the database. Incidently I misplaced its script. How can I see the definition since when I go to all_views table, it shows text as long datatype aand can't be displayed in sql*plus nor am I able to insert it into a new table as it gives error..."illegal use of Long datatype "
Any help will be welcome..
Regards,
Shobhit

at the sqlplus prompt,
set long 50000
Then you should be able to see the entire view definition at the sqlplus prompt.
You should not perform any dml operations in system level tables like all_views, dba_views etc.

Creating .bat for analyzing the Database.

Hi Experts,
I am having a doubt in scheduling database analysis process windows 2003 server.
Every Sunday, we have to schedule the database analysis. just view the below example
sysuser login id : testlogin
sysuser password: demotest
connection string: demotest
file - demo.sql is available in d:\
Now i need to create a .bat file for scheduling purpose.
in the bat file, i want to connect as sysuser and then execute the above mentioned sql file. please suggest me how to give the syntax for connecting to oracle database as sysuser through a .bat file.
One more doubt: we have to analyze the database in sysuser mode only or also in local user mode???
suggest me about this...
Thanks in Advance.

oracle recommends generation of statistics using dbms_stats package with
dbms_jobs package.
You can use following procedure as sys user
variable jobno number;
variable instno number;
begin
select instance_number into :instno from v$instance;
dbms_job.submit(:jobno, 'dbms_stats.GATHER_SCHEMA_STATS(ownname=>'<schema Name>,OPTIONS=>''GATHER'',cascade=>TRUE);', TO_DATE('18-JUN-05--21','DD-MON-YY--HH24'), '(SYSDATE+1)', TRUE, :instno);

In normal view, half the page disappears off right of screen. in full screen this does not happen. what can be done to correct the screen ratio for normal screen?

version 5 loaded on windows 7. all went well for a while. one day while using, ratio of normal screen doubled in width; i.e. half the page disappears off the screen to the right (on a wide screen). when full screen mode applied, ratio is fine. it only happens in normal view, which is the usually prefered option. I cannot determine any means within the program to resize the normal screen. nothing else is affected, only mozilla firefox in normal view. not that when program is opened from keyboard the page is correct for a moment, then enlarges the width with 1/2 page dissappearing.

This issue can be caused by the Babylon Toolbar 1.1.8 extension
