Can I use ODL / OQL on Oracle ?

Hi,
Recently I read a database book, one chapter is about ODL (Object Definition Language) and OQL (Object Query Language). I still dont really get it :
1) Can I use ODL / OQL on Oracle ?
Or it can only be implemented on 'pure ODBMS' only ? (while Oracle is not ODBMS, is it?)
2) If the answer is Yes, does it mean I can access Oracle, e.g : from Java, without any O/R Mapping or JDBC layer ?
Thank you for any help,
Krist

1) No, and Oracle is not a ODBMS (in that you are correct). It is an Object-Relational database.
2) No. You need something like TopLink to do the mapping.
Oracle Lite (on the other hand) does have these features.

Can we use Dynamic SQL in Oracle Reports ?

Hi ,
Can we use Dynamic SQL in Oracle Reports ?
If yes please give some examples .
Thanx
srini

I believe the built-in package SRW.Do_Sql is what you are looking for
Example from the document:
/* Suppose you want to create a "table of contents" by getting the
** first character of a columns value, and page number on which its
** field fires to print. Assume that you want to put the "table of
contents"
** into a table named SHIP. You could write the following construct:
DECLARE
PAGE_NO NUMBER;
PAGE_FOR INDEX NUMBER;
SORT_CHAR CHAR(1);
CMD_LINE CHAR(200);
BEGIN
SORT_CHAR := :SORT_NAME ;
IF :CALLED = Y THEN
     SRW.GET_PAGE_NUM(PAGE_FOR_INDEX);
     SRW.USER_EXIT(RWECOP PAGE_FOR_INDEX
     P_START_PAGENO);
     SRW.MESSAGE(2,TO_CHAR(:P_START_PAGENO));
END IF;
SRW.GET_PAGE_NUM(PAGE_NO);
CMD_LINE := INSERT INTO SHIP VALUES
                      (||SORT_CHAR||,||TO_CHAR(PAGE_NO)||);
SRW.MESSAGE(2,CMD_LINE);
SRW.DO_SQL(CMD_LINE);
COMMIT;
EXCEPTION
WHEN DUP_VAL_ON_INDEX THEN
        NULL;
WHEN SRW.DO_SQL_FAILURE THEN
        SRW.MESSAGE(1,FAILED TO INSERT ROW INTO SHIP TABLE);
WHEN OTHERS THEN
       COMMIT;
END;

Can i use HTML coding in oracle alerts

Hi,
I have a doubt in oracle alerts.
can i use html coding in oracle alerts.
If so can anyone please help me out this.
Thankig you,
Regards,
RR

hi vingorius ,
No you cant include html but u can use variables
To add a variable in a text message to provide context for the iBot attachment
1. Click the following option:
If sent as attachment, include this text
2. Type the text into the text box with a session variable, a repository variable, or a presentation variable using the syntax shown in the following table:
Variable Type
Syntax
Repository @{Variable_Name}
Session @{NQ_SESSION.Variable_Name}
Presentation @{Variable_Name}
For example, Dear, @{NQ_SESSION.Variable_Name}, here is your personalized Weekly Sales Territory Update.
NOTE: If you want to use the @ character, you need to precede it with the \ (back slash) character to separate it from the variable syntax. For example, Dear @{NQ_SESSION.DISPLAYNAME}, \@ New York, appears as Dear Joe Smith, @ New York.

How can I use unix commands from oracle report

I have to use the following command from oracle reports.
In oracle forms we can use the HOST command but what about oracle reports2.5.
I have to email the attached file 100245.pdf from oracle reports to the given email id
uuencode 100245.pdf 100245.pdf | mailx -s "test" [email protected]

Hi,
It's because .bat (or .cmd) files are scripts and not executables and are interpreted using the command line executable - which is normally cmd.exe (although you can buy others).
So you need to call cmd.exe passing the bat file name as a parameter, something like
cmd.exe /c batchfilename
Without the /c you will never get a response.
However, this brings us to the bizarre conclusion that you are going to:
call cmd.exe (a shell interpreter)
to launch a batch file
that calls cygwin (another shell interpreter)
which then runs ls
When shouldn't that just be:
call cmd.exe to run the dir command
Or better yet, If you are just after a file name listing and you seem to understand Java stored procs, why not just write a JSP to list the contents of a directory? No problems with OS dependant commands, scripts and 3rd party interpreters. Plenty of examples of that out on the internet as well.

How can I use firefox to access Oracle's 10g Express Edition Database script editor?

I have installed Oracle's 10g Express Edition (xe) Database in my computer, which is running Ubuntu 10.04 64-bit. I can access the database through the command line and by using the web interface on Firefox. However, the script editor doesn't work with Firefox. The scripts are not shown and I'm unable to edit them.

Can I use owb9.2 with oracle 8i?Urgent!

My customer's source db is oracle8.1.7 and he want to build dw on the same database and he don't want to upgrade his db to oracle9i.
Can I only install owb9.2 on the oracle 8i db and use it to build the dw?
If not how can I solve this problem?

Yingli,
Yes, you can. OWB 9.2 Installation Guide, http://otn.oracle.com/documentation/warehouse.html
page 1-12 "Software Requirements for Warehouse Builder Components":
"Warehouse Builder repository requires Oracle 8.1.7 or Oracle9i Database Server Release 1 or 2."
and
"The server side environment requires Oracle 8.17 or Oracle9i Database Server Release 1 or 2."
The targets can be deployed on even earlier version of the database (starting from 7.3.4). One of the strengths of OWB is ability to design a mapping once and then control deployment to various targets through location definitions which are db version-aware. That in turn generates code appropriate for a given db version. For example, MERGE statement will only be generated if target is on 9i.
Make sure your customer is aware of many performance advantages of running the warehouse on 9i vs 8i, so that he makes the best decision for the project.

Can we use JVM and/or Oracle Multimedia with the Express Edition?

Hi!
I wonder if there is any way to instal/use/activate JVM (implement java classes) and/or Oracle Multimedia?
I want to make a little application that would exploit those features ...
Can we do this with Oracle Express?
If so, how do I proceed?
Thanks everyone.

SadWell...
i was surprised that I have'nt been ask for a licence code or something...That's part of Oracle's distribution concept - you need to think about proper licensing yourself, until you get an audit. As you already mentioned, there could be user licensing - hard to manage with entering codes. On the other hand, there are OTN licensed downloads for development and evaluation purposes that don't need a paid license. Oracle doesn't want to build different packages for that, so you get exactly the same software for development your paying customer has for production.
So...
So, knowing this, is it legal if I install it and exploit it for my own purposes?I recommend reading the OTN license you've accepted before downloading the files.
As I indicated above, it will (usually) allow you develop any application using any database release (including SE or even EE), without additional licensing. You need to make sure you never actually do any productive or testing-like activity on instances that are used under that license. Note that OTN license does not include support, so you are not allowed to install any patch you may have obtained from MOS using one of your companies support ids on such an instance.
is there any 'personnal' licence (less expensive that the $350 per user (minimum 5 users)) i can buy for myself to legally use it?If you think what you do is not covered by the OTN license, there is "Oracle Database Personal Edition". See [url http://docs.oracle.com/cd/E11882_01/license.112/e10594/editions.htm#CJADFHGH]Database Licensing Information for details on the differences between the available database editions. According to the current price list, it's at $460 + $101.20 per year for support at the moment. The cheapest way to get a personal instance with access to patches & co.
BTW: There is also Standard Edition One at $180 per user, but probably still a little too expensive for personal use, because the 5-users-rule applies.

How can I use the CPS for Oracle ECM with webcenter

Hi I did install webcenter "webcenter_windows_x86_101320_disk1" but im not able to use CPS(content portlet suite) anybody used them together before .

Hey Khalid,
I think you might be in the wrong forum. This one is for WebCenter Interaction - the old BEA ALUI/Plumtree product, not the original Oracle WebCenter Portal.
Terrible terrible terrible job in picking such similar names for these 2 different products!

Use css file in oracle 10g report builder

hi every one
i am using oracle 10g report buidler. i want control paramform by usign css file.
any body have idea how can i use css file in oracle report builder 10g and how can i modify it's path and i how can i manage any css class on a perticular field.

Thanks Billy.
Yes you are right.
Here why I discarded that option is,
I may get the source files with changing layouts.
My Actual scenario is as follows.
Initially we developped all the things using PL/SQL packages. Its working fine.
But as per the inputs we received from requirements group, the file structure changes dynamically. and we would able to consider those new columns also. We should be able to changes the rules dynamically.
Lets say, we doing fullouter join on Src_A and Src_B. on columns col1_A and col1_B.
Now the requirement changes in a way that, the join should be done on Src_A and Src_C. on columns col1_A and col_C.
For this I need to define a new package.
Instead of that, I would like to do everything dynamically based on configuration parameters given as input.
Thank you,
Regards,

Only Apple Account Security could help at this point. You can try calling Apple Support in Canada - you'll have to find one of the several ways, such as Skype, to call an 800 number from outside of the relevant country - and ask for Account Security and see if they can help. Or you can find a friend who speaks Chinese and ask them to help you talk to Apple Support in China. There are really no other options that I know of.
Note, by the way, that these are user-to-user support forums. You aren't speaking with Apple when you post here.

Can I use Report Manager to distribute customized oracle reports?

Hi,
Can I use Report Manager to distribute customized oracle reports, other than FSG reports?
If no, is there any function that can be used for distributing reports submitted from concurrent manager in r12.1.2?
Thanks for any advice!
HY

Pl post details of OS and EBS versions.
>

I am not sure - pl ask your friendly Oracle salesperson if this functionality is included in your license.
>

Another option could be to use XML/BI Publisher - again, you will need to check if your license includes distributing custom reports.
