Get No. of Affected Rows After Commit

In my application, I'm showing data in af:table which is editable.
I need to show the no. of rows affected after calling a commit.

Refresh only current row after commit, when ChangeEventPolicy set to none

Hi,
I'm using jdeveloper 11.1.2.3.0
I'm editing a table with a popup, I set the ChangeEventPolicy to none because it made some problems.
Now I would like to know, when i'm closing the popup and doing commit,
how could I refresh only the current row, and not whole the table?
I would like it to work as with ChangeEventPolicy set to ppr.
Thanks!

could you please explain a little bit more?
When I used the ChangeEventPolicy with ppr it looks like only the selected row was changed after commit.
but with PartialTrigger i see that it's refreshing all the table.
are you sure they are working the same?
what about row.refresh(..), is it only used for rollback?

Reset of current row after commit in ADF-UIX

Dear experts,
I have developed an application with Oracle JDeveloper 10g and ADF-UIX using BC4J. The problem is that wherenever a commit is performed the current row for the master table is reset which causes confusion for the end user.
Do you know how can I solve that problem?
Thank you in advance,
Constantine

... I forgot to mention that I use JDeveloper 3.1 on Windows NT4.
About my problem, it seems that a "key" does not exist in the record (Row object) i'm using for.
So, what really is a "key"? Is this an internal complicated number or just the values of some data fields, indicated as "Primary Key" in the table?
If the answer is the second one, I have to say that at the really before commit of the record, the value of my primary key fields is NULL, because they are filled up by a "sequence object" created in the database (triggered by a "TRIGGER BEFORE INSERT", which calls the "sequence.nextval" SQL command).
So, I really have the value of my primary key fields just after committing the record in the database, and would explain everything.
But is really this the "key"?
Thanks

Delete statement: how to get count of affected rows in a variable

Hi folks
I write a proc which deletes data from bunch of table based on data value. i want to produce a report which will have 1 line for each table like:
Del: Table name : number of rows
I parse delete statement into variable and use execute immediate. I know I could precede delete by select count(*) using the same criteria. Is there any more effective way to catch output from execution of 'delete' itself to avoid an overhead of running select count(*)?
Thank you, Gene.

Gene,
I thought you said you wanted to have the number of rows deleted. In that case, see Sänjay's example above.
Btw, is there a particular reason that you are using EXECUTE IMMEDIATE (?)
To have it in a variable
declare
   v_rows_deleted number;
begin
   delete from emp;
   v_rows_deleted := SQL%ROWCOUNT;
end ;Regards
Peter

Iterator refresh after commit

Hi,
I have three tabs in my page , and in each tab , i have separate taskflows.
The first tab taskflow contains a jsff which has lets say master table iterator i.e departments iterator.
In the second tab, i have a table based on read only query, but when i click on add button, i will be inserting in to detail VO (employee VO) and using postChanges() .
so that read-only query based table gets the new data.
now when i click on save button and commit , the iterators in taskflows of tab1, tab2 are pointing to first record rather than the current record.
1) even i tried with having an action for the 'save' button and navigating to method activity which sets the iterator to current row.
When i am returning back to taskflow,i am still seeing the iterator pointing to first record rather than the current record i intend to see.
could anybody tell me why iterator is pointing to first row after commit()
i don't have 'refresh' -- if needed for taskflows. its default.
for transactions, datacontrols, its default for my taskflows.

I generally retain the previously selected row using the following code in my VOImpl after every executeQuery().
public void executeQuery()
// current row key if any
Key currentRowKey = null;
Row currentRow = getCurrentRow();
if ( currentRow != null )
// get current row key
currentRowKey = getCurrentRow().getKey();
// super call
super.executeQuery();
if ( currentRowKey != null )
// set current row now using previously stored key
Row[] rows = findByKey( currentRowKey, 1 );
if ( rows != null && rows.length == 1 )
setCurrentRow( rows[0]);
}

Hi, when can i get the recently deleted rows

Hi,
Where can I get the recently deleted rows after commiting the transactions.
Thanks in advance.

To query your table e.g. one hour ago:
select * from your_table as of timestamp sysdate - 1/24change 1/24 to a number where you think your data were still in the table.

After commit current row is no longer highlighted

JDeveloper 11.1.1.20.
Scenario: a master detail page where master and detail are both ordinary ADF table ( NOT read-only).
If I place the cursor on a master row and do a click the row is highlighted.
If I do a createInsert operation (with a button) a new row is created above the previous mentioned row.
Problem:
If I do a commit after the new row is filled with data sometimes the newly made row is now longer highlighted after the commit.
The newly created row is stil active. This is seen by the fact that if I subsequently creates a new deatil row it is correctly connected to the newly created master row.
And - after the newly created detail row is created the master row is again highligted.
Any ideas?
Best regards
Erik

Hi,
To keep highlight the selected row do some operation in bean ,Get selected row and set that row again after commit

HANA equivalent of oracle's sql%rowcount to get affected rows.

I want to get the number of rows affected from an insert or update statement inside a stored procedure.
Is there any equivalent to oracle's sql%rowcount that can be called after the query.
For example:
create procedure procedure_name
begin
     declare l_c integer;
     insert into table values ('somevalue');
     l_c := sql%rowcount; -- This would return 1 for the row inserted.
end;

Yes, after the INSERT statement....
SELECT ::ROWCOUNT into L_C FROM DUMMY;

Does Update function module gets executed after Commit Work?

Hi Gurus,
I have a BAPI with a Commit work. Does update function module V1 , V2 - i need mainly about the sequence of V2, gets executed after Commit work or before Commit work.

Get the number of rows affected by update statement

Hi
I'm working on an application that uses OCI as interface against an Oracle database.
I'm trying to find out how i can get the number of rows affected by a query executed with OCIStmtExecute. it is not a select query.
Best regards,
Benny Tordrup

If I run a bulk UPDATE query using OCIBindArrayOfStruct, is there a way I can tell which+ rows successfully updated?
I have a file of records of which 75% of PKs are already in the table and will be updated, the other 25% aren't and should be inserted later. I want to attempt an UPDATE statement using OCIBindArrayOfStruct to execute in bulk and then check which entries in my bulk array successfully updated. If an array entry isn't successfully updated then I will assume it should be inserted and will store it for a Direct Path load later.
Many thanks for any advice you can give as I've been trawling through the docs trying to find a solution for ages now.

How Do I get SSIS To Stop Looping Through Excel Rows After Last Populated Record?

I have a package that loops through many excel files. Each Excel File has about 5000 rows. My problem is that after the 5000th row SSIS keeps looping through all the rows after the last row. There are nothing in these rows. This is a complete bottleneck
of my package because it takes forever when doing this. How do I stop this?
Thanks

Another way is to specify the range in select statement which can be done in two ways

Updating row after insert that causes trigger

Hi,
I have a table which one of the columns is a sequence number which each time a new row is written I want to automatically write to this sequence column the latest number (which is maintained using an Oracle sequence). I decided to use a trigger which works great:
CREATE OR REPLACE TRIGGER pre_insert_trg before insert ON INCOMING
for each row
BEGIN
SELECT INCOMING_SEQ.NEXTVAL
INTO :new.SEQ
FROM DUAL;
END;
The problem is I have many multi-threaded processes writing to this table and the sequence number gets allocated before the row is committed which means although thread 1 may write first it may commit after thread 2 which has a later sequence number which has the result that sequence number 2 may be shown before 1. The problem is much larger when dealing with many threads with 100's of messages a second and so I would prefer the seq to be added AFTER the insert (once committed), e.g.
CREATE OR REPLACE TRIGGER post_insert_trg after insert ON INCOMING
for each row
BEGIN
SELECT INCOMING_SEQ.NEXTVAL
INTO :new.SEQ
FROM DUAL;
END;
Trying to create this trigger results in a "ORA-04084: cannot change NEW values for this trigger type". Is there a way to update a column for the row which caused the trigger? If I try and remove the :new. I then get errors when inserting about mutating table (which I understand the DML locking but need a way round)
Many thanks,
John

Off hand I think the only way you can do what you say you want to do is to replace the sequence with a code table. A transaction locks the code table, gets the next value from it and unlocks the code table at the end of the transaction. This ensures that the sequence number is always assigned in transaction completion order (or rather the transactions always complete in sequence assigned order). It is basically what java does with its synchronize statement.
The only drawback with this approach is that it completely shags the performance of the sort of multi-threaded environment you've just described. :P
So you need to decide what's more important: having stuff inserted into a queue in sequence order or having a multi-threaded system running quickly. I really don't see how you can acheive what you're attempting in a genuinely concurrent environment; you'll have to introduce an artificial serialism (ie bottleneck) somewhere.
If you do crack this please tell me how: I would be interested in ordering multiple AQs in the fashion you described.
Cheers, APC

BLOCK THE AFFECTED ROWS

"The option FOR UPDATE is blocking the table instead of blocking the rows returned
by the SELECT .. FROM .. WHERE clause.
Is there any way to only block the affected rows; keeping in mind that I am using Power Builder."

well
it depends. if you design your application to have a mass update , then you may need to lock the entire qualifying rowset.
if you need to process record by record , it is better to include a COMMIT immediately after you complete UPDATE operation.
This immediate COMMIT is to avoid the EXPLICIT locking of records by POWERBUILDER. and This will facilitate other users
by allowing an access to the remaining records in the table.

How to get a Sum of rows, when i use the property max. rows p. page ?

Hi all.
I've got a query and get a lot of rows (amounts) back.
Now i want to have max. 21 rows per page.
So, first i used the property "max. rows p. page"=21.
But i want a have Sum-Field p.page too, which shows the sum of the amount p. page at a >fixed place (bottom, left) at the page.
this didnt work well....
Because when i have 30 rows, then the sum will shown at the second page (because the sum-field its after the repeating frame).
...Now i forgot the property and placed a function and two placeholder in the query like this:
Function:
:cp_row:=:cp_row +1;
if (mod (:cp_row,21)=0)) then :CP_pagenr:=:CP_pagenr+1;
Placeholders: cp_row, cp_pagenr
Now i want to use :CP_pagenr to change the group - but Report Builder says: I cant... because placeholder are not allowed to change a group.
So.. perhaps anyone can give me a hint how i can do this ?
Thanks a lot...

hello.
that sound to me as you wanted a running total. check out the metalink knwoledge base and search for running total and you will find a note on how to do that.
