Can i call stored proc from VOImpl, not from AM?

Hi,
i know how to invoke proc from bb defined in AM...
in VOImpl i have a method getSelectedRows()
which gets me rows selected in table by user.
how can i invoke stored proc from there?

Hi,
its exactly the same code. The only missing link you have is the access to the transaction. In a Viewimpl file just call this.getApplicationModule() to get access to an application module.
The method can also be exposed on a client interface (same as for AM)

SQL Exception: Invalid column index while calling stored proc from CO.java

Hello all,
I am getting a "SQL Exception: Invalid column index" error while calling stored proc from CO.java
# I am trying to call this proc from controller instead of AM

Can I back up stored docs, emails and notes from my iPad -- and not just music and photo's, etc?

Can I back up stored docs, emails and notes from my iPad -- and not just music and photo's, etc?
I see how I can store the latter -- but not the former. And I don't care whether it's to the cloud or to a hard drive, etc.
Thanks!

If you are using iCloud, you don't need to back up these items because they are synced with your iCloud account.

Use 'default' keyword in call string while calling stored proc?

I am calling following sql server stored procedure from java code using my jdbc driver for sql server: CREATE PROCEDURE test_findTbInfo (
@paramIn_Str varchar(10),
@paramOut_Int int OUT,
@paramIn_Int int = 20
AS
begin
set @paramOut_Int = @paramIn_Int * 100
end
If I make a call like this:
CallableStatement cs = conn.prepareCall(" { call test_findTbInfo(? , , ? ) }");
cs.setString(1, "test_tab");
cs.setInt(2, 4);
cs.execute();
It works without any error. But this is not a right behavior. !! The second parameter as you see is passed like an optional parameter. But in stored proc it is NOT an optional param and so if the value not passed it should fail...
Now if I change the code to
CallableStatement cs = conn.prepareCall(" { call test_findTbInfo(? , default, ? ) }");
it works correctly. Gives error that "Procedure 'test_findTbInfo' expects parameter '@paramOut_Int', which was not supplied." which is correct.
So is it a normal practice to use 'default' keyword while calling sql server stored procedures having optional parameters in jdbc ????
Anyone knows ??? As far as I know "call test_findTbInfo(? , , ? )" works fine except in some cases and also it forces users to put all optional parameters at the end of parameter list in stored proc.
Please let me know whether I should go with 'default' throuout for sql server stored proc while calling using my jdbc driver.
Amit

{?= call <procedure-name>[<arg1>,<arg2>, ...]}The question mark in the above is the result parameter
that must be registered.
That is not the same as an OUT argument.Yes that is true. The result value and OUT parameters are different but they both MUST be registered as per jdbc API
"The type of all OUT parameters must be registered prior to executing the stored procedure; their values are retrieved after execution via the get methods provided here."
Anyway, my original question still stays as it was. If there are some optional IN parameters in stored procedure
e.g.
PROCEDURE test_findTbInfo (
@paramIn_Int int = 20,
@paramOut_Int int OUT
how do you call this?
CallableStatement cs = conn.prepareCall(" { call test_findTbInfo( , ? ) }");
cs.registerOutParameter(1, Types.INTEGER);
cs.execute();
or
CallableStatement cs = conn.prepareCall(" { call test_findTbInfo(default, ? ) }");
Also note that I am intending to use ONLY sql server driver for this.
The first as well second seem to work. Except that second way is seems reliable. I just wanted a second opinion on that...

Can I call a .htm page of view1 from another .htm page of view 2?

Hi,
I have a viewset QuestionnaireTabVS with a view area TABS which has two views QuestionCondnsVS (default) and View QuestionRisksVS.
When a variable say GV_TAB is set as 'Questions' it navigates to the QuestionCondnsVS view and when the variable GV_TAB is set as 'Risks' it navigates to the QuestionnaireRisksVS.
This view set QuestionnaireTabVS is contained in an overview page which has two Radiobuttons. It works fine when the first radiobutton is selected, i.e, when I click on the Questions it renders the QuestionCondnsVS view and when I click on the Risks it renders me the QuestionRisksVS view .
Problem is when I had clicked the RISK tab first and then selected the another radiobutton the rendered view QuestionRisksVS doesnt get removed
but is present there by default which I dont want.I want the QuestionCondnsVS view to be present there by default after the second radiobutton is selected. I tried to refresh all the controllers but somehow it navigates to the QuestionRisksVS only .
So i thought to call the .htm page of QuestionCondnsVS forcefully from the QuestionnaireTabVS .htm page as soon as I select the another radiobutton.
Can I call a .htm page of QuestionCondnsVS from another .htm page of QuestionnaireTabVS? If yes then how or any other suggestion is welcome

Hi Dharmakasi,
The Radiobuttons code is not added in the same HTML page but lies in a different component where the coding is on event handler.

Call Stored Proc using SAP JPA

Hi
Can we call stored procedures using SAP implementation of JPA. I had no success till now. I tried to call using named query and native query.
Thanks
Vidyadhar

Hi,
named queries are made for selects that return objects.
You might try to change your stored procedure to a function returning e.g. 1 (number) and call it with "select myfunc from dual".
If you really need named query support for PL/SQL consider to switch to eclipselink. They have extended PL/SQL support in their latest release.

If i want to buy movies,how can i do it? i m not from u.s.

if i want to buy movies,how can i do it? i m not from u.s.

First, check this web page to see if Apple has been able to license movies for sale in your country:
http://support.apple.com/kb/TS3599
If they do offer movies in your country, then you buy them through iTunes or from an iOS device like you would any other content. If Apple does not offer movies in your country, then you will have to look to some other download store.

Oh no! I'm sorry to hear you had problems in the are you're in AkJohnDye. I checked your coverage and I do see we have an extended 4G coverage. This means you're able to use your phone but it needs to be activated in a 4G LTE Verizon Wireless coverage zone. I apologize.

Satellite A105 boot up only from HDD not from Floppy or CD-ROM

Even after C-MOS Set up, system is booting only from HDD not from Floppy or CD-ROM.
Is there any sepcific setting to set these controls in Satellite A-105 Model ?

Hi
Do you mean an external floppy drive and external CD-ROM drive or a one which is built-in?
If you want to boot from the internal CD-rom drive so you have 3 possibilities.
1. Changing the booting order in the BIOS to CD drive
2. pressing the C button immediately after notebook starting
3. pressing the F12 button immediately after notebook starting and choosing the CD drive
I think you should also be sure that you want to boot from the bootable CD.
If the CD is not bootable you will be not able to boot from the drive.
PS: If you want to boot from the floppy drive you can press instead of C button the U button

You don't really delete app that way, that way to stop backup for that app in icloud.
You need to delete it from your home screen and then while it still will look like download from icloud - app will start fresh.
However if app uses any account sign in the stuff that is attached to sign in will come back, so if you do not want to you need to use
fresh account as well.

We are fellow users here on these forums, you're not talking to iTunes Support nor Apple. We won't know what terms that iTunes Support think that you violated, but the most common reason is probably trying to use another country's store - you are in the same country as you have listed on your iTunes account ?
