First you have to create create dblink in A1 database as below
CREATE DATABASE LINK INSA1
CONNECT TO USER_NAME IDENTIFIED BY <pass>
USING 'B!' Then you can execute exec pack_b@INSA1;

Hello,
What do you mean? Something like SELECT mypackage.function( par1, par2) from dual?
Or do you want to execute a procedure when something happens on the page, like clicking a button?

How to call a package from within a package

How would I call a package from within a package and pass variables to it. For instance I am trying to pass variables to a log package from another package when a user inserts or updates a table

First, technical questions need to be addressed to one of the technical forums. Products | Database | SQL & PL/SQL would be appropriate for this question. Please direct any followup to that forum.
Second, you cannot call a package; a package is a collection of stored procedures and functions. You can call a packaged function or procedure from another package simply by specifying the package name and the procedure
CREATE OR REPLACE PACKAGE pkgA
AS
PROCEDURE callPkgB;
END;
CREATE OR REPLACE PACKAGE BODY pkgA
AS
CREATE PROCEDURE callPkgB
AS
BEGIN
pkgB.someProcedure( 'Some argument' );
END callPkgB;
END pkgA;In general, any packaged procedure can be called by specifying the schema, package, and procedure name, i.e.
EXEC mySchema.myPackage.myProcedurethough the schema and package can be omitted if the calling procedure is in the same schema or package.

How to call a function from a different script object?

Hi All,
Here is the scenario,
I have 2 script objects A and B .
In script object A i have a function called "funcA" and
in script object B i have a function called "funcB"
Now I want to call funcA from funcB which is not happening.
I tried doing
A.funcA();
inside funcB , but not able to access.
Kindly help.
Thanks
Abhiram

Hi Abhiram,
Just a guess - try including the root node/node reference above the script object.
form1.A.funcA();
What does the JavaScript Console say when firing the function? Are there any errors?
Your script objects can contain multiple functions. So you could move funcA() and funcB() into the same script object. This will make it easier.

hi, how do i call java files from a different directory??
let say i got partA.java, and i need to include functions from partB.java which is in a different folder. how can i do that?

Hi nuttynibbles,
Before the class declaration in partA.java, you must have an import statement like :
import someDirectory.partB;
public class partA {
... and before you ask... you'll probably want to read through this http://java.sun.com/docs/books/tutorial/java/package/index.html

Transformation is to mapping the source and target of 2 different schemas.

How to call oracle function from ejb3

i'm trying to call an oracle query-function from ejb3.
The oracle function:
create or replace FUNCTION getSecThreadCount(secId in NUMBER,avai in NUMBER)
RETURN SYS_REFCURSOR is cur SYS_REFCURSOR;
m_sql VARCHAR2(250);
BEGIN
m_sql:='select count(thrId) from thread where secId='|| secid||'
and thrAvai='|| avai;
open cur for m_sql;
return cur;
END;
I'v tried several ways to call it,but all failed:
1. the calling code:
public Object getSectionThreadCount(int secId,int avai){
          Query query=manager.createNativeQuery("{call getSecThreadCount(?,?) }");
          query.setParameter(1, secId);
          query.setParameter(2, avai);
          return query.getSingleResult();
but i got the exception:

2. the calling code:

query = "{?=call getSecThreadCount(:secId,:avai)}",
resultSetMapping = "getSecThreadCount_Mapping",

          query.setParameter("secId", secId);
          query.setParameter("avai", avai);
          return query.getSingleResult();
but i run into the exception:

By the way, i have successfully called the function from hibernate. And i use oracle 11g, JBoss5 RC1.
Could anyone tell me how to call the function from EJB3?
Thanks.

}Basically you just ignore the refcursor outbound parameter.
This is a stored function, have yet to try outbound refcursor parameters in stored procedures...

Run Script Logic/Package from a different Application

Hi Experts,
I have a scenario here that I need to run a package from a different application. For example, I'm in Finance application and I need to run a package which is in the LegalApp application, is it possible to call that package or perhaps run the logic it was calling without having switch back to LegalApp.
Thanks,
Marvin

To run a package that runs logic on another application, you could copy a package such as "Default Formulas" and put the name of the target application in the new package's name. Then go to Modify Package --> Advanced. Edit the package to set the application as below. The LegalApp (for example) is set on the third Task command. Default logic is called on fifth.
PROMPT(RADIOBUTTON,%CHECKLCK%,"Select whether to check work status settings when running logic.",1,{"Yes, check for work status settings before running logic","No, do not check work status settings"},{"1","0"})
PROMPT(SELECTINPUT,,,,%CATEGORY_DIM%%ENTITY_DIM%%TIME_DIM%)
TASK(Execute formulas,USER,%USER%)
TASK(Execute formulas,APPSET,%APPSET%)
TASK(Execute formulas,APP,LegalApp)
TASK(Execute formulas,SELECTION,%SELECTIONFILE%)
TASK(Execute formulas,LOGICFILE,)
TASK(Execute formulas,CHECKLCK,%CHECKLCK%)

How to call a function from asp

Hi!, I'd like to know how to call a function from an asp page. I've written:
set rs = server.createobject("Adodb.recordset")
rs.open "call dbo.sf_Obt_Des_Producto ('0000161')",Conn
if err.description <> "" then
response.write ("No se pudo! :(")
else
response.write ("rs: " & rs(0))
end if
rs.close
set rs = nothing
but there is an error:
ORA-06576: not a valid function or procedure name
Please is very urgent!!!
Thanks.
Angie.

You need to use the syntax "{call <procedure_name>}".
The {call } syntax tells the OLE DB provider that it needs to translate the call into whatever the database's procedure calling syntax is. This means that even though different databases have different syntax for calling stored procedures, your OLE DB code can be run against any of them without changing.

While calling plsql package from Pro*c getting ORA-1426 error

Hi Friends
I am calling a package from Pro*c and getting numberic overflow error ORA-1426 but when i introduce a debug message such as printf or calling standard oracle utility to write in a log file no error comes. So how just introduction of debug messages is resolving the error.Can any one throw some light on it, whether it is some kind of synchronization issue or something else
Regards
Abhijeet

Pretty hard to guess here since you're not providing any sample code.
However:
"Internally, PL/SQL assigns the values of the bounds to temporary PLS_INTEGER variables, and, if necessary, rounds the values to the nearest integer. The magnitude range of a PLS_INTEGER is -2147483648 to 2147483647, represented in 32 bits. If a bound evaluates to a number outside that range, you get a numeric overflow error when PL/SQL attempts the assignment. "

Problem while executing my package from a different schema

Hi,
I developed a package.
Now when i try to execute my package( which is in Schema1) from a different schema(Sc2) in the same database(9.2.0.1)
i.e. execute <Sc1>.<package_name.Package_main_proc>;
I'm able to execute the package successfully.. but .. my package is deleting all records in all the tables used by the package !!
If I run the same package from my schema(Sc1).. everything is working fine.
i.e. its deleted only unwanted records after executing the whole package.
Can anyone pls help me.
Regards
Jack

Guido,
I'm sorry for asking a really vague question.
I included all the dbms_output.put_line() in my code. As i executed in my schema. I couldnt find any error.
So now, instead of calling my package from Sc1.
I compiled my package in Sc2( I dint get any errors) and then executed it.
Even now data is deleted from the tables.
So now i tried thru another schema(SC3)..
again compiled it and executed it.. now everything is working fine.
So to my understanding i just there is some dependency is Schema 2. But i'm not able to figure it out as i'm not getting any error.
Am i going is right direction. If not please correct me .
Thanks

How can I transfer songs from two different itunes?

I want to transfer songs from my brother's itunes library to my shuffle, but when I plug it in his computer, a message saying that his library is not linked to my library (or something to that extent) and whether I would like to replace the songs. If I click yes, all my existing songs are replaced with HIS songs. If I click on NO, the Shuffle icon does not appear at all and I cannot transfer any of his songs to my shuffle. How can I transfer songs from two different computers into my shuffle without replacing any of my existing music?

You'll have to setup your iPod to manual instead of automatic update (I'm not sure, though, if it works with the Shuffle as well).
