Calling UDF From Cursor

I have a table in which there is a xml data type column for storing xml data. I want to call my function foreach xml data record from a SQL query and when result returned then check intersection of two polygons by STIntersections method. The function accept
xml data as input parameter and returns geography data in the format
POLYGON((66.9214310204
30.1191654521,66.9724466643 30.1273507980,66.9612156084 30.1614246796,66.9324717194 30.1540007613,66.9214310204 30.1191654521))
Below is the code that I have tried but not giving me the results
Declare @aoi geography
Declare @xml xml
Declare @result geography
SET @aoi=geography::STGeomFromText('POLYGON((66.9214310204
30.1191654521,66.9724466643 30.1273507980,66.9612156084 30.1614246796,66.9324717194 30.1540007613,66.9214310204 30.1191654521))',4326);
--creating cursor to hold results for function calling
Declare xmlDataCursor CURSOR for select XmlFiles.xmlData from XmlFiles
OPEN xmlDataCursor
FETCH NEXT FROM xmlDataCursor INTO @xml

Calling BRM from UDF using JNDI lookup with @EJB annotation

Hi Experts
I am trying to implement a UDF to invoke my BRM Rules set via JNDI Lookup instead of a SOAP Channel lookup.
I have had a look at the following links/docs:
Calling BRM from UDF using Public API
http://www.gleanster.com/system/resources/W1siZiIsIjIwMTIvMDgvMDcvMjAvNDcvNTAvNDMvVGhpbmdzX1lvdV9TaG91bGRfS25vd19hYm91dF9TQVBfTmV0V2VhdmVyX0JSTS5wZGYiXV0/Things%20You%20Should%20Know%20about%20SAP%20NetWeaver%20BRM.pdf
For item 1 above, the example looks really good, but it doesnt explain how I get access to the following required imports from my UDF:
import com.sap.brms.qrules.ejb.*;
import com.sap.brms.qrules.engine.AbstractProject;
import com.sap.brms.qrules.engine.RuleEngine;
import com.sap.brms.qrules.engine.RulesetContext;
import javax.ejb.EJB;
The second document is really good as well, but I could not figure out how to get it to work from my UDF.
So, can anyone help me to understand specifically what is required to get this to work?
Is is possible to invoke the rule set from my UDF?
How do I give my UDF access to all the required jars/imports?
I have manage to create a new DC (Development Component) with a public part and this enables me to get my code to compile on my local PC but I am not able to activate it due to the server not having access to the same java packages as my local copy.
Any help would be greatly appreciated.

You resolve the dependency by importing the required jars with using the dependency tab for the mapping program.
As stipulated before, I have managed to resolve the dependency issue but I have now getting the same error as in the forum: Calling BRM from UDF using Public API
The specific error is:
com.sap.engine.services.cross.PortableRemoteObjectContainer.narrow(PortableRemoteObjectContainer.java:238)
Has anyome manage to get invoke a BRM Ruleset using JNDI?

Problem calling a ref cursor that is in a stored procedure

I have a stored procedure that returns a ref cursor as follows and I want to call it from another procedure in the same package. It compiles, but when I run it, it gets errors.
procedure procGetRefCursor(p_string in varchar2, p_int in integer, p_return out sys_refcursor) AS
l_subrefcursor l_refcursor;
begin
open l_subrefcursor for
SELECT myval
FROM mytab a
WHERE myval1 = p_string;
end procGetRefCursor;
The following code compiles, but when I run it it errors out on the fetch.
ERROR at line 1:
ORA-01001: invalid cursor
I also tried opening the cursor first and that does not compile. I also tried
fetch p_return.myval in l_myval
that does not compile
procedure callGetRefCursor(p_string in varchar2,p_int in integer) is
p_return sys_refcursor;
l_myval varchar2(100);
begin
procGetRefCursor(p_string, p_int, p_return);
loop
fetch p_return into l_myval;
dbms_output.put_line('myval '||l_myval);
exit when p_return%notfound;
end loop;
end;

Where is l_refcursor defined?
And why?
Aren't you using SYS_REFCURSOR?

NLS Error on Second Fetch from Cursor

Oracle 8i using PRO*C
We have a UNIX (HP) environment (operational account) in which the NLS_LANG was not set for the shell. One of our applications opened a cursor for update and performed its first fetch. After processing it went back to fetch an additional buffer. At this point, the application failed with the following error: "SQLCODE: ORA-01890: NLS error detected". When we set the NLS_LANG enviroment variable this error disappeared.
I need to know what the NLS_LANG enviroment variable is doing and why it is causing the second fetch to fail when it is not set so I can argue with the powers that be to have this paremeter always set for this accounts shell (i.e. globally). No-one really knows what this does here or why it would cause the cursor to fail, and so they are telling us to just set the variable in our own applications shell.
I know the real answer to this is to set it up for the operational (global) shell but...
Thanks in advance,
Bill Rosmus

it is difficult. The main problem is that you can't be sure that the function is called only once for each row.
Why don't you simply run the cursor and the function separatly in pl/sql.
CURSOR myCur IS SELECT myTable1.* FROM myTable1 ;
SUBTYPE myRecType IS myCur%ROWTYPE ;
funcResult varchar2(100); /* use the correct return datatype from your function here */
FOR myRec in myCur LOOP
      BEGIN
         funcResult := myPackage.myFunc(myRec.column1);
      EXCEPTION
         WHEN myPackage.myFunc_Exception THEN
           <... do anything when fetched but function myFunc raised this exception ...>
      END ;
      <...do anything with row currently fetched>
   END LOOP;You even have more control where to handle the exception. Also there is one pl/sql context switch less. Since the function itself is pl/sql it could even be faster to run it in pl/sql then to call it from sql (inside a select).

Call vbscript from Apex button

I have added a vbscript to the header section of my page and I'm trying to call this from a button. Is this possible? Can anyone post an example of how this would be done. I've tried calling from the URL redirect section, along with many other things and can't get anything to work. I'm not sure if I added in the header wrong or if I'm calling it wrong.
Thanks

What about placing outputs from the procedure to fields on the form?
Here is the procedure I have created:
procedure vatTotal (Order_no IN number,Total2 OUT number)
AS
CURSOR c_vatTotal is
select order_line.quantity, gre_product.cost from ord, gre_product, order_line where ord.order_no = order_line.order_no AND
gre_product.prod_no = order_line.Product_no;
Total number;
begin
Total:= 0;
for c_record in c_vatTotal loop
Total := Total + c_record.quantity * c_record.cost;
end loop;
Total2 := Total;
end;
I believe this is correct. It compiles.
I tried using Total as an out parameter but received the "duplicate fields in RECORD, TABLE or argument list are not permitted" error.

Getting data from CURSOR

Hello everbody,
I am having a quite funny problem with cursor. I need to get dynamic data from CURSOR.
Example of calling my cursor is:
FOR v_item IN c_item(ExampleXML) LOOP
SELECT TEST_SEQ.nextval INTO pRecord(rLevel).ID;
pRecord(rLevel).PARENTID   := v_item.PARENTID;
pRecord(rLevel).CHILDID      := v_item.CHILDID;
END LOOP;
With this cursor I am able to get CHILDID and PARENTID from XML file and dynamic ID from sequence. Result set should looks like this:
ID PARENTID CHILDID
*1 22 31*
*2 22 32*
*3 32 33*
*4 32 43*
I have no option to save this data however.
Is there any way that I can query or use this temporary data from cursor to get something like:
*SELECT ID from [result set above] WHERE CHILDID = PARENTID*
So, besicaly, I need to select ID for CHILDID, but where PARENTID is same as CHILIDID.
Any idea?

OK, then why not directly :
INSERT INTO your_target_table (id, childid)
SELECT test_seq.nextval
     , xtab.CHILDID
FROM XMLTable(
       XMLNAMESPACES(DEFAULT '...')
     , 'for $item in $Prod//Item
        let $parent_item := $item/../..
        return
        <output>
          <childid>{$item/ItemID}</childid>
          <parentid>{$parent_item/ItemID}</parentid>
        </output>'
      PASSING XMLColumn AS "Prod"
      COLUMNS
        PARENTID VARCHAR2(4000) PATH 'parentid',
        CHILDID VARCHAR2(4000) PATH 'childid'
     ) xtab
WHERE xtab.PARENTID = xtab.CHILDID
; or even this, with the predicate pushed into the XQuery itself :
INSERT INTO your_target_table (id, childid)
SELECT test_seq.nextval
     , xtab.CHILDID
FROM XMLTable(
       XMLNAMESPACES(DEFAULT '...')
     , 'for $item in $Prod//Item
        let $parent_item := $item/../..
        where $item/ItemID = $parent_item/ItemID
        return
        <output>
          <childid>{$item/ItemID}</childid>
        </output>'
      PASSING XMLColumn AS "Prod"
      COLUMNS
        CHILDID VARCHAR2(4000) PATH 'childid'
     ) xtab
;

Calling ShowCursor from C++

I'm working on a Java application that already embeds Flash, direct show video, and other native code. Since this application has the occasional need to be in a kiosk mode, I am attempting to find a way to hide the mouse cursor without having to modify every one of our native controls.
I'm attempting to use JNI and have successfully created an example that can cause the system to beep and move the mouse cursor to 0,0 -- just to prove that my method is alive -- but the call to ShowCursor does nothing and I don't understand why.
extern "C"
JNIEXPORT jint JNICALL Java_com_pvue_test_AthenaCursorControl_SetCursorVisible
(JNIEnv *jenv, jclass theClass, jboolean isShown){
int result = ShowCursor(isShown);
//while (ShowCursor(FALSE) >= -1 ) ; //uncomment to just hide the cursor
// Do these just to prove this method is alive
SetCursorPos(0,0);
MessageBeep(0x00000040L);
return result;
}I'm calling this from Java after the JFrame has been completely laid out and is visible. I'm a total Win32/C++ newbiew so I assume there must some some prerequisites to be able to have ShowCursor have any effect.

Calling report from form. Need PDF output

I am calling a report from a form using RUN_PRODUCT. I need to display the form in PDF format. When the user clicks the button in the form to run the report, acrobat reader should open up and the report displayed there. Please help.
Thanks

Thanks for the response. The first part worked. I am able to get the output in PDF format. In the 2nd part where I want to open acrobat and display the output, I am having some trouble with the code. When I compile, it says
win_api_environment.read_registry must be declared. Is there some package I need to attach?
Also, in the After reports trigger, how do I pass vFile (I am assuming this is the PDF file name)?
Thanks
The first thing you'll want to do is pass parameters to the report IE DESTYPE, DESNAME and DESFORMAT where these could be FILE, 'c:\temp\report' and PDF.
Then, you can try this piece of code I wrote (with some help from other people at Metalink and here) sometime back. Now, I call it from forms, but in your case, you'd have to run it in the after report trigger. Since with RUN_PRODUCT you don't know when the report is finished, if you did it from the form, it wouldn't work correctly.
PROCEDURE OPEN_PDF(vFile IN VARCHAR2)

vcServerApp varchar2(40);
vcServerTag varchar2(600);

iArgPos pls_integer;

vcServerApp||'\SHELL\OPEN\COMMAND';
vcCommand:= win_api_environment.read_registry(vcServerTag,'',true);

Contact name not showing in call/sms log even when I call/sms from my address book.

Two things have changed on my phone recently.
1. I ran the latest update 4.3.2
2. My phone was not showing all the contacts in my address book that is in my Mobile Me account. Mobile me had 166 contacts. The iPhone 4 had 136. I I unchecked the syncing of my contacts on my phone. This removed all the contacts from my phone. Then I check the syncing options again. All 166 appeared on the phone.
I'm not sure which of the two caused the issue but now anytime someone who calls their name does not appear on the display or log, just their number. I can even call people from my address book and the display shows that I am calling them with their name and photo on display. However, in the call log the name does not show just their number. This applies for text messages. I send a message directly from within the contact card in the address book and in my text log it shows only the number and not the name.
I've turned the phone off and on a couple of times.
I would appreciate any advice.
Cheers

Thanks iraghib,
In the end I reset my phone to factory settings. I created a back up of my address book and ical. Reset the phone and did a sync again. This fixed it all. I didn't need to use the backups but is was nice to know they were there. I felt entering the various passwords for all my installed apps was a much better deal than adding the international area code to the 166 contacts I have in my address book.
Good luck. And thanks for the post.

How can I access my Call Handlers from outside line (outside district)

CISCO VoIP System Info:
Cisco Unity Connection version: 8.6.2ES25.21900-25
CM Admin System version: 8.6.2.21900-5 on C200M2 Servers
Our engineer setup our Call Handlers so that in our to change the recordings on them, you diall 7800 from a phone inside the office, or as he put it in the procedures, from within the district. Once you dial, you need to enter the user code, password, then the extension of the Call Handler, and we have no problems recording/changing any Call Handlers. However, due to possible inclement weather approaching in the next few weeks, I was asked how we cna change them from an outside line (manager's home, etc.). We cannot access from an outside line. 7800 is not a DID, it is simply the extension he assigned to access the call handlers. I even went so far as to setup a dummy phone and forward it to 7800, but this does not work either. It forwards to the extension's voicemail. Is there a way we can access the Call Handlers from an outside line? Any help would be gretaly appreciated. Thank you in advance.

Hey Joseph,
Go Flames ....errrrrrrrrrrrrrrrrrr maybe not so much
What you are trying to get to is really just the Greetings Administrator
conversation and there are multiple ways to get there.
For example, you can set up a Caller Input off any mailbox (Press 1-9) let's say 7 to
go to Conversation> Greetings Administrator. So you could set this on the managers mailbox
and when he calls his own number from home once his greeting
kicks in he can press 7 to link to the Greetings Administrator conversation
or
You could set up a DID DN xxx-xxx-2345 as a CTI-RP and set Call Forward All to reach Unity Connection.
In this case you will need to use the Forwarded Routing Rules = xxx-xxx-2345 route to
Greetings Administrator. Make sure to move this rule to the bottom of the list!!
Cheers!

Call tcode from alv report and passing group of values

hi all .
i want to call tcode from alv report and passing an internal table or group of values to a selection option of that t code ? how
ex. passing group of GL to fbl3n and display the detials of all .
thank you

Dear,
You have done a small mistake
--> rspar_line-option = 'EQ'.
rspar_line-HIGH = PDATE-HIGH.
u r passing "high" value and in "option u r passing "EQ" so how it will work!!!
So if u r passing only 1 date or more dates like 01.01.2010 , 15.02.2010 , 10.03.2010 then pass
rspar_line-selname = 'SO_BUDAT'.
rspar_line-kind = 'S'.
rspar_line-sign = 'I'.
rspar_line-option = 'EQ'.
rspar_line-LOW = PDATE-HIGH.
APPEND rspar_line TO rspar_tab.
or if u r passing low & high date means in range like 01.01.2010 to 30.01.2010, then pass
rspar_line-selname = 'SO_BUDAT'.
rspar_line-kind = 'S'.
rspar_line-sign = 'I'.
rspar_line-option = 'BT''.
rspar_line-LOW = PDATE-LOW.
rspar_line-HIGH = PDATE-HIGH.
APPEND rspar_line TO rspar_tab.
try above code , hope it helps...

Could be a third party app preventing you from being able to login.
Mac App Store: Sign in sheet does not appear, or does not accept typed text
If it's not a third party issue, follow the instructions here.
Quit the MAS if it's open.
Open a Finder window. Select your Home folder in the Sidebar on the left then open the Library folder then the Caches folder.
Move the com.apple.appstore and the com.apple.storeagent files from the Caches folder to the Trash
From the same Library folder open the Preferences folder.
Move these files Preferences folder to the Trash: com.apple.appstore.plist and com.apple.storeagent.plist
