Can I call a function in another package?

Dear all,
Can I call a function in another package?
Say I have package A, and package B.
Is it possible for me to call a function in inside package A, within a function inside package B?
If yes, what's the syntax.
Thanks in advance!

The variable in the calling package that will receive the value of the function in the other package needs to be defined based on that type in the other package directly:
sql>create or replace package pkg_a
2 is
3    type testTable is table of varchar2(10) index by binary_integer;
4
5    function f_a return testTable;
6 end;

Call a function inside a package from a stored procedure

Hello:
I am kind of new to the stored procedure. Does anyone know how to call a function inside a package from another stored procedure?
I have a existing function (func_b) inside a package (pack_a) and it returns a cursor. I want to call this function from a stored procedure (proc_c) so that I use the data inside the cursor.
can I do the following in proc_c:
my_cursor1 SYS_REFCURSOR;
begin
my_cursor1 := exec pack_a.func_b
end
It will be very helpful if anyone can point me to any reading or example. Thank you very much for your information.

guys:
Thank you for your information so far. I need some more help here. I was able to run the function in my stored procedure. However, I was not able to print the result on the screen to view the cursor result, although I am using dbms_output.put_line statement inside my stored procedure.
I use the following statement to execute my stored procedure on sql*plus. I can tell the stored procedure is executed successfully, but I did see anything printed:
DECLARE TEMP VARCHAR2(100);
BEGIN PROC_LAWS_CAD_NAME_SEARCH('LPD', 'TEST DEVICE ID', 'TEST LAST NAME', 'TEST FIRST NAME', 'F', '11112009', TEMP); END;
I tried to use 'set serveroutput on' and got the following error:
ERROR:
ORA-06502: PL/SQL: numeric or value error: host bind array too small
ORA-06512: at line 1
I am kind of confused now. thank you for your help.

Can you call a procedure inside another procedure and how many?

Ok. I have 3 procedures. I would like to call 2 of the from inside one, but I would like them to be in order.
So,
procedure1 // this is in db1
     call procedure2
            this collects, and inserts data into table 2 from db1
            this must be run first
     call procedure3
           this update the table1, and table2 from db2, and db3
           this must be run second
     finish procedure1
           this also updates table1 and table2 from db1 and db3
           this must be run third
procedure1 end;or should I call a function
procedures 2, and 3 have there own dblinks to other dbs to gather datat, procedure1 is in the same db.
the procedures dont have to be like above. If you want to run proc3, and call proc1, and proc2 first so be it. Just an example

create or replace myPackage
is
procedure1;
procedure2;
procedure3;
end myPackage;
create or replace myPackage body
is
procedure1 is
begin
    -- call 2
    procedure2;
    -- call 3
    procedure3;
end procedure1;
procedure2 is
begin
    do_something_here;
end procedure2;
procedure3 is
begin
    do_something_here;
end procedure3;
end myPackage;
/* now run the procedure1 from sql*plus */

Can't call a function inside another function

Hello,
i have the following function :
FUNCTION test_day_week (P_DATE DATE)
RETURN VARCHAR2 IS
BEGIN
RETURN TO_CHAR(P_DATE ,'DAY');
END;
--it returns the day name of a given date
FUNCTION TEST_DAY_NUMBER (P_DAY_NAME VARCHAR2)

     V_RESULT NUMBER;
     V_RETURN_DAY VARCHAR2(30);
     P_DATE DATE;
BEGIN
V_RETURN_DAY := test_day_week (P_DATE );
MESSAGE('V_RETURN_DAY'|| V_RETURN_DAY);
MESSAGE('V_RETURN_DAY'|| V_RETURN_DAY);
IF V_RETURN_DAY = 'MONDAY' THEN V_RESULT :=1;
     END IF ;
IF V_RETURN_DAY = 'TUSEDAY' THEN V_RESULT :=2;
     END IF ;
IF V_RETURN_DAY = 'WENDSDAY' THEN V_RESULT :=3;
     END IF ;

END IF ;
IF V_RETURN_DAY = 'SUNDAY' THEN V_RESULT :=7;
     END IF ;
RETURN V_RESULT;
END;
--The above function returnds the day name in numbers
The proble is that when i call test_day_week function it returns no value even it is tested separatly and works fine don't know where is my problem :
1-number of argrments in function[b] TEST_DAY_NUMBER
?? and so ..!
Regards,
Abdetu..

You could also cut the whole thing down to a simple function... (assuming you have a need to customise your start of week rather than use built in date functionality)

I was just curious to know, what will happen in this case
CREATE OR REPLACE PACKAGE BODY "TESTUSER"."TESTPKG" as

n number := 0;
begin

end;
end testpkg;';
Is it valid to have dblink inside a package body?

RegardsSure it is. You can have a database link inside a package code. Moreover, you'll get the name of that database link in the REFERENCED_LINK_NAME column of the DBA_DEPENDENCIES view

Calling native methods in a package

Hi!
We have a problem when calling native methods in a class which is in a package. As you can see from the code below we have a class making an instance of a class<testBando> which makes a instance of another class<Bando> which contains the native methods. When running the program we get the error:
Exception in thread "main" java.lang.UnsatisfiedLinkError: initialize
at test2.Bando.initialize(Native Method)
at test.testBando.<init>(testBando.java:10)
at Main.main(Main.java:5)
When we take the class that calls the native methods out of any package every thing works fine! Can you not call native methods inside a package or what are we doing wrong?
// testBando.java
package test;
import test2.*;
public class testBando {
Bando b;
public testBando() {
     b = new Bando();
     b.initialize();
// Bando.java
package test2;
public class Bando {
public native void initialize();
static {
     System.loadLibrary("bando");
// Main.java
import test.*;
public class Main {
public static void main(String[] args) {
     new testBando();

I suspect that your problem is that you have not
regenerated the signature when you placed the native
method's object in a package. Or same result but different sourc:
-package name was changed and it wasn't regen'd
-javah was run incorrectly (which gens the signatures with no package name.)

Can't access tables in PL/SQL package

I'm trying to create my first package/stored procedure. Been to class, so I don't think the problem is with me. In a real environment now. My schema/user has access to tables in another schema, plus create procedure priviledges. I compiled the package spec OK, but couldn't use %Type. I had to specify the datatype. The package body won't compile with the error message "Error: PLS-00201: identifier 'PTI_PROD.SC_MSTR' must be declared". I can run the SQL just fine in SQL*Plus. Why can't I access tables inside a package. We didn't have this problem in class.

steven. the oracle error msgs documentation says that maybe there is no access privelege to the table. this looks like a privelege issue. grant priveleges explicitly on those tables accessed by your procedure not through any roles.
in your case login as pti_prod and type
grant select,insert,update on sc_mstr to user1;
this shld work.

Can we call an ODI package from another ODI package within same Project?

hi All,
Can we call an ODI package from another ODI package within same Project?

What you can do is get all the interfaces on the old package that you want to be included in the new package. This way, the new package will have the exact code from the old package.Or generate a scenario out of your ("old") package and drag&drop the scenario in the "new" package.
That seems easier to me, because you can re-use the scenario as often as you want.
But you have to take care: If you change your original ("old") package, you have to regenerate the scenario, otherwise the changes do not affect the scenario.

Bind variable inside a package

or is there any alternative for bind variables inside an package
Thanks in advance

The "VARIABLE O VARCHAR2(20);" syntax is the way SQLPlus declared bind variables - it is specific to the client. Because PL/SQL packages and procedures are server code that continue past sessions, its only access to the client environment is what the client gives it - it can't go and create a bind variable in the client.
PL/SQL procedures, functions and packages run from lots of environments, so they cannot access bind variables inside their body - you have to pass any external variables as parameters.
Anonymous PL/SQL blocks can access bind variables.
You can declare package public global variables - just leave out that "VARIABLE". E.g.
CREATE OR REPLACE PACKAGE GET_EMPLOYEEDETAILS
IS
PROCEDURE GET_FIRSTNAME(E_ID IN EMP.EMPNO%TYPE, F_NAME OUT EMP.ENAME%TYPE);
O VARCHAR2(20);
END GET_EMPLOYEEDETAILS ;
For local variables in your procedure, just put them between the IS and BEGIN. Using them in SQL inside the PL/SQL automatically uses them as a bind variable.
create or replace PROCEDURE GET_FIRSTNAME(E_ID IN EMP.EMPNO%TYPE, F_NAME OUT EMP.ENAME%TYPE)
IS
O VARCHAR2(20);
O2 VARCHAR2(21);
BEGIN
O := 'FR%';
SELECT ENAME INTO F_NAME FROM EMP WHERE EMPNO = E_ID and ENAME like O;
O2 := F_NAME || '2';
DBMS_OUTPUT.PUT_LINE(F_NAME);
END;
O is bound in the query.
To access bind variables from anonymous PL/SQL, first declare them in the calling environment. In SQL Plus that's
VARIABLE O VARCHAR2(20);
In Pro*C it's
EXEC SQL BEGIN DECLARE SECTION;
char[21] O
EXEC SQL END DECLARE SECTION;
Then reference it in anonymous PL/SQL with a colon as prefix:
BEGIN
SELECT FIRST_NAME INTO :O FROM EMPLOYEES WHERE EMPLOYEE_ID = E_ID;
END;
This only works for anonymous blocks (starting with BEGIN or DECLARE). As I said, PL/SQL procedures, functions and packages cannot see bind variables from the calling environment
