Retrieving latest updated or inserted records without using a trigger

I have to retrieve the latest updated/inserted records from a set of database tables. Say, if 'n' sets of different records have been updated or inserted into one or more different database tables then all the 'n' records of data should be retrieved using a java code without using a trigger.

Thanks for your reply.
But I don't know when or from where or what kind of data gets inserted/updated into the tables. I need a listener or a component which can handle events occured on the particular set of database tables, and get the event data. the java code should get the updated/inserted rows that have been inserted into a set of database tables by a third party.
Please lemme know how I can do this.Realistically you can't.
If and only if the tables have a modification timestamp then you could use that. Every table would need it.
Other than that the only othe possibility would require that you keep an entire copy of each table in the memory, poll at a set interval and then do an entire comparison for each table. For very small data volumes (on the target tables) that is practical. For larger volumes it isn't.

Select distinct records without using distinct

hi experts,

now i want to select one record for each cnt_id without using any distinct function .. how can i do that?
regards,

you can use the below query
select * from t where rowid in (select max(rowid)
from t group by cnt_id)You're query is not the equivalent of DISTINCT.

How can i display recent update/delete/insert records in form

Hai !!!!
i am new for forms,.......any body tell me, how can i display recent no of records updated or no of records deleted or no of records are inserted in a form. these records count are display in display items....give me detail explination......
Subbu.....

the easiest way is copy and paste the oracle-forms example from the OU.
You need form-level-trigger ON-ERROR + ON-MESSAGE, POST-INSERT, POST-UPDATE, POST-DELETE, three global variables and a procedure:
ON-ERROR
handle_message( error_code, 'ERROR: ' || ERROR_TYPE || '-' || TO_CHAR(ERROR_CODE) ||': '|| ERROR_TEXT );
ON-MESSAGE
handle_message( message_code, MESSAGE_TYPE || '-' || TO_CHAR(MESSAGE_CODE) || ': ' || MESSAGE_TEXT );
PROCEDURE handle_message( message_number IN NUMBER, message_line IN VARCHAR2 ) IS
BEGIN
    IF message_number IN ( 40400, 40406, 40407 )
    THEN
      DEFAULT_VALUE( '0', 'GLOBAL.insert' );
      DEFAULT_VALUE( '0', 'GLOBAL.update' );
      DEFAULT_VALUE( '0', 'GLOBAL.delete' );
      MESSAGE('Save Ok: ' ||
        :GLOBAL.insert || ' records inserted, ' ||
       :GLOBAL.update || ' records updated, ' ||
       :GLOBAL.delete || ' records deleted !!!' );
      ERASE('GLOBAL.insert');
      ERASE('GLOBAL.update');
      ERASE('GLOBAL.delete');
    ELSE
         MESSAGE(message_line );
          END IF;
END;
POST-INSERT
DEFAULT_VALUE('0', 'GLOBAL.insert');
:GLOBAL.insert := TO_CHAR( TO_NUMBER( :GLOBAL.insert ) + 1 );
POST-UPDATE
DEFAULT_VALUE('0', 'GLOBAL.update');
:GLOBAL.update := TO_CHAR( TO_NUMBER( :GLOBAL.update ) + 1 );
POST-DELETE
DEFAULT_VALUE('0', 'GLOBAL.delete');
:GLOBAL.delete := TO_CHAR( TO_NUMBER( :GLOBAL.delete ) + 1 );try it

Have you tried syncing once and then try transferring purchase again? Syncing should trnafer them during the sync process.
Also make sure that you don't have content that you bought with another Apple ID that needs to be transfered as well.

Your site is recommended by a site and after the latest update of firefox, I cannot use your site like I use to do.

the site farmtowngifts.com worked very well prior to the latest update of firefox and firefox is even recommended by this site. Now it is not working properly.

uninstalled firefox ....deleted all files still remaining under mozilla firefox directory in program files ... to avoid having to reprogram all my settings, reisntall all addons as well .. I did not remove anything from mozilla firefox that is stored in either appdata or under the windows users directory (if any)
... the as suggested reinstalled the latest version of the firefox browser using the link you provided in the email ..; tested and several issues still remain present and unresolved ....
so please this is urgent or I will have to jump browsers and start using chrome .. because we work 14 hours a day 6 (sometimes 7) days a week, to get ready for the launch of our newest venture and we cannot lose that much days on browser related issues ... so please instead of putting me through week long step process .. of do this .. do that .. can you please actually look into the issue from your end .. I use firefox for so many, many years thta I deserve this kind of support .. thnx Robert

HOW TO: Create a JSP Insert Record Form Using BC4J Data Tags

This is a JDeveloper Tech Note found on the OTN Documentation page. This note describes the use of the BC4J data tags to create insert/submit JSP pages. Here is a link:
http://technet.oracle.com/docs/products/jdev/technotes/datatag_input/Insert_Form.html

You can loop throgh query records whit an implicit cursor (which automatically manages the open cursor, fetch and next record):
for rec in (select intime,outtime,barcode,attend_date from dail_att; )
loop
     t_in :=rec.intime;
     t_out :=rec.outtime;
     t_code :=rec.barcode;
     t_date := attend_date;
         PUT YOUR CODE HERE ... (if ..then... elsif... logic)
         you can avoid setting variables 'cause you can directly use the implicit cursor variables: rec.intime etc.
end loop;
END;Anyway, I suggest you to check the where condition of your block ... because if not all data are retrieved there should be a problem in your query ... so even the cursor (if based on very same query) will return less data than expected.

Stored procedure returning multiple records without using SYS_REFCURSOR

Hello,
I am new to oracle stored procedures, have done stored procs in SQL server in past. I am trying to write single stored proc which will return multiple records. I have the stored proc as below and that is compiled without any errors.
We don't want to use SYS_REFCURSOR as output param b'coz the place from which this proc is gonna call, that system doesn't support SYS_REFCURSOR param.
create or replace
PROCEDURE p_get5500DATA_MB (
IN_plan_ID IN T_5500DATA_QWP.Plan_ID%TYPE,
IN_plan_ID_col OUT T_5500DATA_QWP.Plan_ID%TYPE,
p_SEQNUM OUT T_5500DATA_QWP.SEQNUM%TYPE,
p_HEADER_CD OUT T_5500DATA_QWP.HEADER_CD%TYPE,
p_VALUE1 OUT T_5500DATA_QWP.VALUE1%TYPE,
p_VALUE2 OUT T_5500DATA_QWP.VALUE2%TYPE
) AS
BEGIN
SELECT
Plan_ID,
SEQNUM,
HEADER_CD,
VALUE1,
VALUE2
INTO
IN_plan_ID_col,
p_SEQNUM,
p_HEADER_CD,
p_VALUE1,
p_VALUE2
FROM TRS1DBO.T_5500DATA_QWP
WHERE Plan_ID = IN_plan_ID
ORDER BY SeqNum;
-- EXCEPTION
-- WHEN OTHERS THEN
-- RAISE_APPLICATION_ERROR(-210001, 'Error in fetching data from T_5500DATA_QWP....');
END;
Error:
ORA-01422: exact fetch returns more than requested number of rows
ORA-06512: at "TRS1DBO.P_GET5500DATA_MB", line 10
ORA-06512: at line 11
My questions is:
- What would be the best practice for this type of simple stored procedures?
- Is there any alternate or is there anything i can fix in above stored proc which return multiple records?
Thank you,
Vimal

Just out of curiosity, what are you using for API or driver that doesn't support a ref cursor? Ref cursors are pretty much the defacto standard for passing multiple records out of an Oracle procedure. Oracle's ODP.NET, OLEDB, ODBC, JDBC, OCI, all support ref cursors. Chances are that if the driver you're using doesn't support something as basic/fundamental as a ref cursor, it's probably also not going to support something else either.
You'll most likely want to check with the driver/api vendor on their recommended approach.

Inserting transitions without using footage

Hi,
I have a transition question, (relating to FCP X 10.0.3), I'm adding transitions between clips, I seem to recall that I used to drag a transition across, and as I got to insert it the clips would automatically part and the transition would drop in.
Now when I drag a transition, FCP X says it needs to use footage from either side to generate the transition, and generate it or cancel it. This is fine with long clips but not so good with the short ones. Does anyone know what I need to change to get this behaviour back?
Thanks in advance

You don't seem to be aware of the importance of having HANDLES. Handles are pieces of your clip before and after the part that is used in the timeline. The handles are what FCP X uses when you create a transition.
When you select part of a clip inside an event (by dragging or setting an In and an Out point), and then insert this selection in a timeline, the outer bits of your clip that didn't get selected - i.e., the Handles - will be used for transitions. If you select ALL your clip, there are no handles. This has nothing to do with the length of the clip.
Having handles is the right way to do it and I hope that you will come to appreciate it.
If you force a transition without having handles, all your content to the right of the transition will be shifted, and the length of your movie will be reduced. This is BAD, as it will mess up things. For example, if you have a sound clip connected to your storyline and some images further down the story were synched to a beat in the music, they will become out of sync.

API to update or insert records in BPA

Hi All,
We do a regular activity fo updating the BPA lines or inserting in our projects via dataloader. It is very cumbersome as sometimes we need to modify or insert 5k lines.
We get the records in a flat file(xls or sometimes in txt format).
Can anybody pls let me know the procedure to write an api for it. It would be of great help if somebody gives me step by step guidance
Thanks
