How to fetch data from a SAP BW Cube via Perl/PHP on a Linux machine?
Hi all,
here's the scenario:
I need to fetch data from a cube of a remote SAP NetWeaver 7. The data will later be used in a web application based on Linux and Perl/PHP. (I'd prefer using perl for the backend and doing the business logic of the web application.)
I have:
A Linux system with all its on-board tools and scripting languages.
A user for the SAP BW which allows me to logon (very,very limited user rights, no se37,no se80,no rsaX and so on)
Access to http://<SAP BW Server>:<Port>/sap/bw/xml/soap/xmla with the above mentioned user.
My questions:
- Could you please push me into the right direction how I can realize this? E.g. by pointing to tutorials / HowTos / sample code / CPAN modules etc.. (Most information I found so far referred to software based on a different operating system and on remote function calls using custom functions.)
- I'm aware of the SAPNW::RFC CPAN module, but do I necessarily have to perform a remote function call? ( If so, is there a "standard" function I could call for accessing a cube?)
Thanks a lot in advance!You can take through the RFCS .check for some system function modules...but why do you need to route it through XI?How huge z the files?

How to fetch data from different sources into one source (like into Ztable)
hi friends,
As per our client requirements they want to develope an Inventory and an Ontime delivery report in BO on top of Oracle database.
Situation is some thing like they have ECC 6.0.and they want to collect all inventory and ontime delivery data at one place.According to me that could be one Ztable in which we can gather all data.Apart from that they are going to use Data Integrator in which they can directly fetch the data from R/3 system(They dont want to have BI system) and put all data in Oracle DB.On top of ORacle BO person can develop BO reports.
My question is how to fetch all data at one place and what are the tables going to be use.
kindly help me out as its very important project.
Thanks
AbhishekThe following is my standard reply to those who need to get old data from a backup in one account and add it to another account. The method described here may be applied to your case. It would be a bit of a long process, though.
When connected to the account you want to GET data from, Go to Settings>iCloud and turn all data that is syncing with iCloud (contacts, calendars, etc.) to Off.
When prompted choose to keep the data on the iPhone.
After everything is turned off, scroll to the bottom and tap Delete Account. Next, set up a new iCloud account using a different Apple ID and turn iCloud data syncing for contacts, etc. back to On. When prompted, choose Merge. This will upload the data to this new account.
Note that this only affects the "Apple data" like contacts, calendars, reminders, etc. Many third party apps also use iCloud to store data files there. These files may be lost in the process, unless the apps also keep the data locally on the device.
NOTE: Photos in the photo stream (if you use it) will not transfer to the new account. It is advised that you save the photos to a computer before performing the account switch. -

How to fetch data from database in javafx 2.2 table which is editable.
Dears!
I want to fetch data from database in javafx 2.2 tableformat with jdbc , which is also editable and i can add more records in this table also.
Can anybody help meI can vaguely recall some sort of JavaFX database connectivity feature, I'm not sure if it's valid anymore.The link is based on JavaFX Composer which only applied to NetBeans 6.9 and JavaFX 1.x (both of which are now dead techs).
There is a good chance you will have to write your own. There are several blogs describing other peoples' work. You could probably use them as a reference.Here is Narayan's basic [url http://blog.ngopal.com.np/2011/10/19/dyanmic-tableview-data-from-database/] tutorial for displaying data from a database in a TableView, you'll need to look elsewhere for the editing portion.
The [url http://docs.oracle.com/javafx/2/ui_controls/table-view.htm]JavaFX TableView tutorial gives info about how to handle edits in a TableView, but you will need to tie the updates back to the database yourself.
It is possible that [url http://www.javafxdata.org/]DataFX may provide some facilities to help support you. -
How to fetch rows from PL/SQL table(Collections)
Hi,
I retrived rows from the table and stored in to table type.
Now I want fetch these rows and display on the screen. Pls guide me.
following code is my code:
DECLARE
type t1 is table of emp%rowtype index by binary_integer;
var1 t1;
v_counter number:=0;
BEGIN
select * bulk collect into var1 from emp;
for vr in var1.first..var1.last
loop
dbms_output.put_line(var1(1)); --Got an Error Here. Acually I don't Know how to fetch.
update dept set deptno=var1.deptno --Here also Error occured.
end loop;
END;Fetching rows to display them is a task for the client tool. You need to define a ref cursor therefore.
If you just want to play around, here we go
SQL> DECLARE
2 type t1 is table of emp%rowtype index by binary_integer;
3 var1 t1;
4 v_counter number:=0;
5 BEGIN
6 select * bulk collect into var1 from emp;

How to fetch records from the database into a combo box?
Hi:
I´m really new with ABLBPM and I´m trying to fetch records from the database to display them into a combo box as valid values for a presentation but I´m using a dynamic method with this code:
<em>for each row in SELECT campo1, campo2 from TABLE</em>
<em>do</em>
<em>solicitudes[] = [row.campo1, row.campo2]</em>
<em>end</em>
<em>return solicitudes
</em>And the debugger says that SQL instructions can be used only in fuctions and procedures that are executed on the server.
Do you know another way to do it?
P.D. Sorry for my terrible english
GreetingsHi Steve,
Thank you, your idea is perfect, but when I try to run the screenflow where the combo should be filled I get this error:
