Update/insert/delete in the same JSP

Dear all,
i want to develop a same JSP from which can update,delete or insert..is it possible??
thanks in advance..

The form display is dictated by how you process the submit. I would build the form by using standard html tags. Here is another pseudo example:
<FORM ACTION="target.jsp" >
<TABLE>
<TR>
<TD>
DeptNo
</TD>
<TD>
DName
</TD>
<TR>
<%
int nRow = 0;
%>
<jbo:RowsetIterate datasource="ds">
<%
// increment the row number
nRow++;
String sDeptno = "Deptno" + nRow;
String sDname = "Dname" + nRow;
String sRowKey = "RowKey" + nRow;
%>
<jbo:Row id="myrow" action="current">
<TR>
<TD>
<input type="text" name="<%=sDeptno%>" value='<jbo:ShowValue dataitem="Deptno" />' />
</TD>
<TD>
<input type="text" name="<%=sDname%>" value='<jbo:ShowValue dataitem="Dname" />' />
<input type="text" name="<%=sRowKey%>" value='<jbo:ShowValue dataitem="RowKey" />' />
</TD>
<TR>
</jbo:Row>
</jbo:RowsetIterate>
<input type="submit" />
</TABLE>
</FORM>
NOTE: This should get you started!!!

Update/Insert/Delete into the same table

Hi,
I'm writing pl/sql code :
nvoice_id will be passed as parameter and based on invoice_id I need to see whether any records exist in history table.If not any then insert record into table.If more than one record exist then I need delete all except most recent one based hist_seq column in that table.
Then I need to update that record for description column .How to put dml operation one after another in an efficient manner?As one statement depend on another do I need to use autonomous transaction?
Thanks,
Kiran

create procedure p_deal_with_invoice
   p_invoice_id number
   l_max_hist_seq number;
is
begin
select max(hist_seq)
into l_max_hist_seq
from your_table
where invoice_id = p_invoice_id;
if l_max_hist_seq is not null
then
   delete from your_table
   where invoice_id = p_invoice_id
   and hist_seq != l_max_hist_seq;
   update your_table set some_columns = some_new_value
   where invoice_id = p_invoice_id
   and hist_seq = l_max_hist_seq;
else
   insert into your_table () values ();
end if;
end p_deal_with_invoice;
/An autonomous transaction would probably be the last thing you'd want here. Just a simple plsql procedure that accepts a INVOICE_ID as an input.

What's the exact trigger for when updating/inserting/deleting data from one DB to another DB which contains same info?

Hi guys,
I have created a copy of the AdventureWorks2012 DB called AdventureWorks2012_new on the same instance.
I have created the following trigger below but my friend who is a DBA told me that this is not correct and I should be using the inserted table when creating this trigger. I would like AdventureWorks2012_new DB to be updating/inserting/deleting data from
the same tables that have been updated/inserted/deleted in the AdventureWorks2012 DB. How exactly should I do this for all the tables in the whole database ? What I have written below is just for one of the tables, is there a quicker way to do it for all tables
in this DB so that it performs the actions mentioned above, automatically ? Help would be greatly appreciated so I can understand how this works, thanks
CREATE TRIGGER [HumanResources].[tr_HumanResources_AfterUpdate]
ON [AdventureWorks2012].[HumanResources].[Department]
AFTER UPDATE
AS
BEGIN
SET NOCOUNT ON;
UPDATE AdventureWorks2012_new.HumanResources.Department
SET Name = t2.Name,
GroupName = t2.GroupName,
ModifiedDate = t2.ModifiedDate
FROM AdventureWorks2012.HumanResources.Department AS t2
INNER JOIN AdventureWorks2012_new.HumanResources.Department AS t1
ON t2.DepartmentID = t1.DepartmentID
END

For insert it's easy:
CREATE TRIGGER [HumanResources].[tr_HumanResources_AfterInsert]
ON [AdventureWorks2012].[HumanResources].[Department]
AFTER INSERT
AS
BEGIN
SET NOCOUNT ON;
Insert INTO AdventureWorks2012_new.HumanResources.Department
(DepartmentID, Name, GroupName, ModifiedDate)
SELECT DepartmentID, Name, GroupName, ModifiedDate
FROM Inserted;
END
I didn't verify column names, so you may need to make sure to use correct column names for that table.

Insert and Delete at the same time?

Hi,
I have a dynamic list and dynamic form. When a person inserts a record using the dynamic form, I would like to delete a record from another table using a foreign key when the new record is added (assuming a record exists in the other table). Is this achievable, and if so, can anyone provide any help?
Thanks in advance for any advice provided.

As kendenny says, this appears to be a misunderstanding of how database transactions work.
As Hoek says, if it's an insert and delete on the same table, there is a MERGE statement that can help do that as a single statement.
However, you do not do an INSERT from one table and a DELETE at the same time from another table. But that doesn't matter, because that's the point of logica transactions on a database.
You perform your insert, which starts a transaction (if one isn't already started).
You then delete from your other table (which adds to the transaction)
When you're happy that both things are done, you COMMIT your transaction which then applies those changes.
If you're not happy with something you can ROLLBACK, and that will undo all the changes from the transaction.
So, the commit and rollback allow the changes to be applied as one logical unit, even though the changes are applied in multiple steps.

Materialized Views: how can I find the number of updates, inserts, delete

We are using Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - Prod.
In a materialized view, with fast incremental refresh, done after every 5 minutes automatically, I want to store in a logging table the number of rows inserted,updated and deleted in the materialized view by that refresh.
One option is to create a job that should read the materialized view log table just before the refresh and store the required information in the logging table. But this information may not be accurate.
Is there any other way to collect this information for each refresh?

Use auditing, or an before insert/update/delete trigger, that updates a counter
I hate myself for giving this advice, because it will bring you problems, with the MV update/refresh speed, table lock contention on the log-table....
Be carefull !!
Why not use auditing on the source table and why does anyone wants to know the number of changes??

Update/insert/delete data from xcelsius to Database via web service

Hi,
I need to create dashboard that go function can <b>update/insert/delete</b> data send to <u>Database</u> thru <u>web services</u>, as i know got 2 xcelsius add-on software which support those of function <b>InfoBurst</b> and <b>flynet </b>
<b>InfoBurst</b>
http://www.infosol.com/azbocug/minutes/4-Writeback%20to%20a%20Database%20with%20Xcelsius.pdf
<b>flynet </b>
http://www.flynetviewer.com/public/community/Blogs/FlynetXcelsiusServerUser/default.aspx
Except this 2 purchase add-on xcelsius, any other solution ?
Maybe need to write some in MSSQL or C# programming which enable insert, update, delete ...etc ?
*note: i not use Xcelsius Engage Server , i use Xcelsius Engage only
thanks,

Hi,
As of now in Xcelsius/Dashboard Design there is no feature or functionality to insert/update/delete data from database.
Solution:
Create a Web service in let’s say C# or Java, which will perform insert/update/delete operation.
In Xcelsius add Web Service connection and user above web service.
Xcelsius Web Service connection provides option to pass input values to a Web Service (Input Pane) and get the result (Output values pane).
We can pass values to be written to the database as a input to Web Service via Web Service connection from Xcelsius and write data to the database.
Note:
Performing delete operation from Xcelsius Dashboard could be risky and may delete important data from database. I would not prefer giving delete option/functionality in Xcelsius dashboard.
Hope this helps!
Thank you.

I get an error message that says library not loaded and the reason is image not fund. I have reloaded IDVD and also done an update but still have the same problem. Anyone have any ideas on how to fix it?

I get an error message that says "Dyld error Message: Library not loaded @rpath/ilifeslideshowcore.framework/versions/a/ilifeslideshowcore" the reason: image not found
Anyone have any idea how to fix this problem. I have reloaded the software from the original disk and have downloaded the latest update and still get the same error.

Did you delete all receipts with iDVD in the file name with either a .PKG or .BOM extension that reside in the HD/Library/Receipts folder and from the /var/db/receipts/ folder before installing the new copy? If not then do so and delete the new application also.

More than one business component (views) in the same JSP page

Hi, I am trying to have more than one business component (views) in the same JSP page as Input Form.
For example:
There are two BC4J:
Person:
Code.
Name.
Address:
     Person_code
     Street.
     City.
There is a master detail relationship between them and there is a link between both views in the application module.
I want to create a JSP page with an Input form for both views. When the user decides to create a Person, I need to insert in both tables.
Insert code and name into Person table.
Insert Person_code, Street and City into Address table.
It is possible to do in Forms but I am not sure if I can be able to do this in JDeveloper 10G.
Thanks

Sorry I lost the tabs
Person has two attributes Code and Name.
Address has three attributes Person_coden Street, City.

Once I accept a calendar invite on my iPhone, I cannot delete or otherwise modify it. Even when it is updated or deleted by the invitor, it does not change on my iPhone. Is there a fix for this?

Once I accept a calendar invite on my iPhone, I cannot delete or otherwise modify it. Even when it is updated or deleted by the invitor, it does not change on my iPhone.

My husband and I both have iphone 4's and we both have this same problem. I have an open ticket with apple, but so far they haven't been able to figure this out. First, they told me the problem was the mail server I was using. So, I tried sending/receiving invites from gmail and yahoo which they told me should work. Neither did. It doesn't matter whether the original invite was created in iCal or in Outlook or Google, once I open the invite in my mail and hit "add to calendar" the event is locked into my calendar. If the originator sends an update or cancels the meeting, I will receive an email with the new info, but the event doesn't change in my iphone calendar. This is completely lame. Why bother putting a calendar app on the phone if it can't handle basic functions?
Did you ever get a response from anyone or figure out a workaround? I'll post if I hear back from Apple with a fix.

When I delete an email from my hotmail account in the 'mail' application on my MacBook Pro, it is not deleted from the same 'mail' application on my iPhone 4s which my hotmail account has also been added. I thought my emails were synced over iCloud?

It is so frustrating because I cannot understand what is wrong. When I add an event to my calender on my iPhone it appears in my calender on my MacBook which is perfect and very convenient. The same thing occurs with reminders; everything syncs perfectly here. However when I delete an email from my MacBook from the 'mail' appliaction it doesn't delete from the same built-in application on my iPhone. This is extremely frustrating as I have to delete the same email twice on two different devices. I'd appreciate any feedback that would help resolve this problem!

Calendars (and contacts) can "sync" between your MBP and your iPhone through iCloud because they really live on the iCloud servers and the two devices are clients. iCloud can accomplish much the same trick for email messages because the email really resides on iCloud email servers.
If the email resides on some other server, that server is responsible for whatever syncing will be done. IMAP servers like the iCloud servers are built for such syncing; other mail servers may or may not be. iCloud would not be involved with email other than iCloud email.
I understand Hotmail has been changing how their email servers are accessed. Check with Hotmail support for any changes you may need to make to keep up.

Show master and detail viewobjects in the same jsp

I have two viewobjects which have a master-detail relationship (a viewlink between them).
What I want to do is to show both the master and the detail data in the same jsp, i.e for every row in the master viewobject I want to show all the rows in the detail viewobject.
I tried to drop the master vo on the page from the component palette and then the detail vo next to the master vo, but then only the first row in the detail vo is shown on the page. I want all of them to be shown.
Can anyone please point me in the right direction here?
Ps: I'm using JDeveloper version 9.0.5.2
Thanx a lot
Tom

I dropped both viewobjects as read-only tables and they both have the rangesize set to -1.
I think I made myself a bit unclear when asking my question. I do not want a "normal" master-detail view in my jsp where you see one masterrow and all the detailrows. I want my page to show all the masterrows with all their corresponding detail rows listed under the master row.
The pseudocode may look like this:
for each row in MasterViewObject loop
<<display data in MasterViewObject>>
for each row in DetailViewObject loop
<<display data in DetailViewObject>>
end inner loop
end outer loop
As you see I have a double loop here. Is somehing like this possible without "manually" doing all the stuff?
Thanx
Tom

Updating two tables at the same time

How to get error message on the same jsp

Hi guys,
I have a login.jsp page and I want an error message to be printed "login failed" in the same jsp page when the user enters the wrong credentials.
Any ideas on how to do that is highly appreciated.
Thanx in advance.sri

If you use struts it would have been a lot easier and better than only JSP.
In struts :
Add this line in ur JSP page
<html:errors/>
In ur Action servlet ex: LoginAction.java add thsi code extract in the appropriate position ...
ActionErrors errors = new ActionErrors();
errors.add(ActionErrors.GLOBAL_ERROR, new ActionError("error.user.wrong"));
if (!errors.isEmpty())
saveErrors(request, errors);
But in JSP do something like this:-
If authentication fails then post to the same JSP and put this code in the reqd position...
<%
String postFlag=request.getParameter("postFlag");
if(postFlag.equals("FAILED"))
%>
LOGIN FAILED
<%
%>
So for JSp simply set the request parameter (postFlag) to SUCCESSFUL/FAILED from your servlet.

Trigger in mutation - Update another rows in the same table with a trigger

Hi ,
I try to do a before update trigger on a table , but the trigger is in mutation. I understand why it do that but my question is :
How can I update other rows in the same table when a UPDATE is made on my table??????
Here is my trigger :

A standard disclaimer, the mutating trigger error is telling you that you really, really, really don't want to be doing this. It generally indicates a major data model problem when you find yourself in a situation where the data in one row of a table depends on the data in another row of that same table. In the vast majority of cases, you're far better off fixing the data model than in working around the problem.
If you are absolutely sure that you cannot fix the data model and must work around the problem, you'll need
- A package with a collection (or global temporary table) to store the keys that are modified
- A before statement trigger that initializes the collection
- A row-level trigger that adds the keys that were updated to the collection
- An after statement trigger that iterates over the data in the collection and updates whatever rows need to be updated.
If you're on 11g, this can be simplified somewhat by using a compound trigger with separate before statement, row-level, and after statement sections.
Obviously, though, this is a substantial increase in complexity over the single trigger you have here. That's one of the reasons that it's generally a bad idea to work around mutating table exceptions.

Error while trying to open the same JSP page.

Hi partners,
After solving some issues with JSP deployment, we are getting another error message.
This is when we try to open the same JSP page at the same time.

I mean this is a concurrency problem.
Any information about this will be really appreciated.
Best regards!!!!!

After running the BI_Checkconfig tool I got an inconsistent OLAP API Metadata
result, it was because a partner was modifying the OLAP metadata without saving
the changes.
After saving the changes in the OLAP metadata, I ran the BI_Checkconfig tool
again with success (no metadata errors).
Now the pages are displayed without any error message.
Best regards!!!!
