Query from remote database

Hi
i have a table named "gatepass" in database A.
i created public synonym
(create public synonym gatepass for schema.gatepass@databaselink) in database B for the table "gatepass" in database A.
when i query that table in db B through SQL prompt, it fetches data.
but when i query that table through form, form hangs(goes into working state) and ends.
where is the problem
plz help
thanx

i use forms 6i.
in your database B create a view:
create or replace view gatepass_v as
select * from schema.gatepass@databaselink
and then create a synonym public over the new view.
and in your form use the sinonym public or the view.
test please.

Select type_address in Portal report's sql query using remote database

how do i select type_address item from remote database table ?
I've already create the database link called db_link.
I've already execute the sql statement in the specified database, and it works.
for example: ( sql plus in the specified database )
select syk.alamat_syarikat.alamat1 from MCS_SYARIKAT syk
for example: ( sql statement in portal report using database link )
select nama_syarikat, syk.alamat_syarikat.alamat1 from MCS_SYARIKAT@dblink syk

Display BLOB from remote database

Context: We are offloading documents (pdf) from our OLTP database to a dedicated 'output database.' These documents must be displayed from the application on our OLTP database using a database link. Various posts show that querying a BLOB from a remote database can best be implemented using a query on the remote table and an insert on a local (temporary) table. So far, so good. The idea is to display this BLOB using wpg_docload.download_file.
BUT:
When trying to display the pdf from this global temporary table an error occurs:
ORA-14453: attempt to use a LOB of a temporary table, whose data has already been purged
When trying to display from a normal table and issuing a rollback after wpg_docload.download_file results in another error:
ORA-22922: nonexistent LOB value
When trying to display from a normal table and not removing the record in any way, its works fine. Only I now have a garbage collection issue, because the remote date remain in my local (preferably temporary) table.
It seems to me that mod_plsql needs an active session to display my pdf.
Does anyone have an explanation for this behaviour and maybe a solution for my problem?
Environment:
local: 10.2.0.4.0
remote: 11.1.0.7.0
pdf size: ca. 150kB
code used:
PROCEDURE show_doc (p_nta_id IN NUMBER
,p_sessie IN NUMBER
IS
t_lob BLOB;
t_lob2 BLOB := empty_blob();
t_mime VARCHAR2(100);
BEGIN
-- copy BLOB into local global temp table
INSERT INTO mvs_tmp_notaprint_bestanden
npv_nta_id
, npv_npe_sessie
, mime_type
, bestand
) -- from remote table
SELECT npd.npv_nta_id
,npd.npv_npe_sessie
,npd.mime_type
,npd.bestand
FROM mvs_notaprint_bestanden@marc npd
WHERE npd.npv_nta_id ; = p_nta_id
AND npd.npv_npe_sessie = p_sessie
-- show BLOB from local global temp table
SELECT t.bestand
, t.mime_type
INTO t_lob
, t_mime
FROM mvs_tmp_notaprint_bestanden t
WHERE t.npv_nta_id ; = p_nta_id
AND t.npv_npe_sessie ; = p_sessie
t_lob2 := t_lob; -- buffer BLOB
owa_util.mime_header(t_mime , FALSE );
owa_util.http_header_close;
wpg_docload.download_file(t_lob2);
END show_doc;

Andrew,
thank you, the 'preserve rows' did the trick.
Every query from a browser (even in the same browser session) is a new Oracle session, so the copied records in the global temporary table are gone after the page is displayed.
Am I correct in assuming that each call from the browser results in a new Oracle session? I did a few tests and found for each call a different sessionid.
Sincerly,

MV Incremental Refresh on join query of remote database tables

Hi,
I am trying to create a MV with incremental refresh option on a join query with 2 tables of remote database.
Created MV logs on 2 tables in the remote database.
DROP MATERIALIZED VIEW LOG ON emp;
CREATE MATERIALIZED VIEW LOG ON emp WITH ROWID;
DROP MATERIALIZED VIEW LOG ON dept;
CREATE MATERIALIZED VIEW LOG ON dept WITH ROWID;
Now, trying to create the MV,
CREATE MATERIALIZED VIEW mv_emp_dept
BUILD IMMEDIATE
REFRESH FAST
START WITH SYSDATE
NEXT SYSDATE1/(24*15)+
WITH PRIMARY KEY
AS
SELECT e.ename, e.job, d.dname FROM emp@remote_db e,dept@remote_db d
WHERE e.deptno=d.deptno
AND e.sal>800;
Getting ORA-12052 error.
Can you please help me.
Thanks,
Anjan

Primary Key is on EMPNO for EMP table and DEPTNO for DEPT table.
Actually, I have been asked to do an feasibility test whether incremental refresh can be performed on MV with join query of 2 remote database tables.
I've tried with all combinations of ROWID and PRIMARY KEY, but getting different errors. From different links, I found that it's possible, but cannot create any successful testcase anyway.
It will be very much helpful if you can correct my example or tell me the restrictions in this case.
Thanks,
Anjan

Xmltype data can't be copied from remote database

Hi,
I got the following same error when copy table with xmltype from different env:
table localXML(xml xmltype);
insert into localXML select * from remoteXML@romote;
1. run from db tools:
... Physical database connection acquired for: local
12:07:41 [INSERT - 0 row(s), 0.000 secs] [Error Code: 22992, SQL State: 99999] ORA-22992: cannot use LOB locators selected from remote tables
... 1 statement(s) executed, 0 row(s) affected, exec/fetch time: 0.000/0.000 sec [0 successful, 0 warnings, 1 errors]
2. run from sqlplus
ORA-22992: cannot use LOB locators selected from remote tables
The above script runs well if two tables are in same database.
Did any one have solution on this?
Thanks.
John

The standard workaround for this one is to create a synonym or such on the be called object and then do the insert selecting via the synonym. Search google for ORA-22992 and "asktom" and see if this workaround for LOB's also works for xmltype (CLOB) columns/tables.
What's your database version and how was the remoteXML table created (DDL) ???

Getting LONG RAW from remote database

Hi,
I have a table in my local database that has a LONG RAW column . I have another table of similar structure in a remote database (so it has LONG RAW as well). I would like to transfer data including LONG RAW data from the remote database into the local database table using PL/SQL. I know it is not possible to copy LONG RAW over dblink directly. Can anyone suggest an approach to accomplish this?
The local table cannot be changed to BLOB, but I have the flexibility to change the remote table to use BLOB. So, can anyone tell me if the following solution would work. If so, can you shed some light on what PL/SQL libraries to use or can you provide me with some sample code to implement steps 3 and 4 below?:
1. Change the remote table to use BLOB
2. Create a new temporary table with BLOB in the local database.
3. Copy data using PL/SQL from remote BLOB to local temporary table BLOB.
4. Copy data using PL/SQL from BLOB to LONG RAW within the local database from temporary table (w/ BLOB) to the actual target table (w/ LONG RAW).
I think step 3 can be a direct Insert-Select from remote table (I'll try this myself), but not sure how to go about step 4.
Thanks for your help.

There is a chapter in the Oracle Application Developer's Guide on calling external procedures
I don't know enough about VB and the available VB APIs to know for sure. I would assume that VB could be configured to generate a DLL with a C call specification. I would also assume that there was a VB API that would allow you to manipulate LONG RAW and BLOB data. Unfortunately, though, I don't know which VB API's have that functionality.

The document is in different database and used by other schemas as well from that database.
.Net is GUI.Daniel raised a very important point. Moving that document via another database doubles the network load for that operation. And doubles the performance impact on the client.
Is this in any way a sensible thing to do? Most definitely not.
Assuming that the client cannot reach the remote database containing the documents, and that can only be done via the local database, then you need to look at options such as materialised views. Replicate the remote content from the remote database to the local database at regular intervals.
As the data set is large (containing LOB documents), consider fast incremental refreshing (and not pull the entire data set across with each refresh).
Yes, you can write PL/SQL code that grabs the remote document and copies it into a local LOB and then dish that up to the client. But the impact of this on the network and performance are major concerns that need to be thoroughly evaluated first.

Trouble creating forms from remote database

Hi,
We are having problems with connecting to remote databases with portal. We can create reports fine from the remote databases but when we try to create forms, it gives the error:
'This Table does not exist or you do not have the required privileges (WWV-13020)'.
We've created a link to the remote db, and synonyms for each of the tables. I don't understand because it seems we can build reports and other components...just not forms.
If anyone has any ideas as to what the problem could be, any assistance you may provide is greatly appreciated!
Thanks!

Sarah,
It could be dull, but anyway - make sure that you granted all the required grants (INSERT,UPDATE,DELETE) in addition to SELECT to the application schema.
Also, at which step of the wizard you recieve this error?
Thanks,
Dmitry<HR></BLOCKQUOTE>
Dmitry - we're having the same problems...
I've had our DBA team grant us every possible privilage we can find - but I still can't create a form from within the portal to a remote database. The wizard lets me put in the table name, ex. asset.wban_trans@drsrch, and does come up with the proper columns on the layout page of the wizard, but when I click the "Finish" button I get the following errors: Line/Column Error
733/21 PLS-00454: with a returning into clause, the table expression cannot be remote or a subquery
733/9 PL/SQL: SQL Statement ignored
841/16 PLS-00454: with a returning into clause, the table expression cannot be remote or a subquery
841/9 PL/SQL: SQL Statement ignored
The form is then listed in my applications list, but if I try and run it I get the following error:
Error: An unexpected error occurred: ORA-04063: has errors
ORA-04063: package body "PORTAL.FORM_0305092506" has errors
ORA-06508: PL/SQL: could not find program unit being called (WWV-16016)
Thanks for any help....

Querying from a database

Hi,
I would like someone to help me coding the search from a database.
I have a html document which asks for a title or an author. My servlet should execute the query using the given title or author retrieving data from the database.
I am trying to execute this query which i know as in sql.
Select Authors.FirstName, Authors.LastName, Titles.Title from Titles, Authors, AuthorISBN where (FirstName = req.getParameter("keyword") OR Title =req.getParameter("keyword") ) AND Authors.AuthorID=AuthorISBN.AuthorID AND AuthorISBN.ISBN=Titles.ISBN
I am getting sqlexceptions if i execute this query in the jdbc. Please someone help me in coding this in jdbc appropriately.
Thank you.

You are getting errors because that string is not valid SQL. Write a string expression that does produce valid SQL, something like this:
String sql = "Select Authors.FirstName, Authors.LastName, Titles.Title from Titles, Authors, AuthorISBN where (FirstName = " + req.getParameter("keyword") + " OR Title = " + req.getParameter("keyword") + " ) AND Authors.AuthorID=AuthorISBN.AuthorID AND AuthorISBN.ISBN=Titles.ISBN;
You'll have to hack around with it to make it work. I am willing to bet you don't get it right the first time. Use System.out.println(sql) to check what you are producing.

Error messages from remote database

Hi.
While working across database links, usually the error messages occurring on the remote database are displayed without particulars like datafile name, tablespace name, etc. e.g. ORA-03232: unable to allocate an extent of blocks from tablespace , which should ideally say ORA-03232: unable to allocate an extent of 100 blocks from tablespace TEMP. This, probably is because only an error number is passed back from the remote database or because the other parameters passed back are not being picked up properly by the local database (client). Is there any way to get around this? It should not be something like 'add a parameter in the remote procedure for getting back the error text'!
Thanks,
Rahul

The alternative of course is to make your process which does the insert into the table conditional upon the username not already being present in the table. It give you the overhead of an additional data fetch but this should be negliable unless you have a very large table with poor index usage.

Hi,
Use Proxies For Your Sender SAP System side and Use the Appropriate Adapter at Receuver side according to the Requirement
Now scenario willl be Proxy-Xi---
Logic:
1) Write the Logic inside the Proxy report to pick the records from the tables
2) And send it to Xi, Xi will routew the data to the third party System based on the adapter you selected

At One Part Of The Presentation (Minute 0:26:00 specifically) When He Try To Search A Specific Record In the Database
And He Got all this annoying Messages Then The Record what He looking Shows up ; He Said That We No Longer able to Modify The Record After We Doing the Search
My First Question Is Why ???
Is there anyway After I got that Specific Record I Want from the Database I Can make my modification on it and update it Back in the DB.
OR i Have to Browse the whole DB looking for it Specially that I got this (ID Auto Increasment Number field Issue) Which leads me to ;
My Second Qustion;
Why I Can't just connect ''The Form Order Number'' to an Auto Increasment Number field in the DB
Obviously i can't, So Can I do Anything to achieve this goal ??
I Believe that we can Find some scripting to make that Happen
I Will Be So Grateful If There Is Any Helpful Answer
FYI: I'm Not Java Expert So If There Is any Coding That's Can be Helpful Please POST ALL OF IT if you can ,,,,

Hi,
The information there is excellent and I would strongly recommend it.
I don't have any public database examples and I am not inclined to spend time preparing an example if you are not prepared to read up on the methods.
Stefan's site is the only link I have for databases.
Good luck,
