Call a function in a package body

I am new to Oralce, I am tried to call a function in an exiting package body using the package specification. function.
But it failed , it says wrong numbers or types of parameters. I see the functions are defined in the package body with two definitions but different numbers of parameters. One has only one parmenter, the other has 3.
But in the packgage definition is has the function with one parameter.
So when I call using 3 parameters, it gives the error.
Why is that?
Thanks

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

How to get a called procedure/function name within package?

Hi folks,
is it possible to obtain a called procedure/function name within package?
For a measuring and tracing purpose, I would like to store an info at the beginning of each procedure/function in package with timestamp + additional details if needed.
For example:
CREATE OR REPLACE PACKAGE BODY "TEST_PACKAGE" IS
   PROCEDURE proc_1 IS
   BEGIN
      api_log.trace_data(sysdate, 'START.' || ???????);
      api_log.trace_data(sysdate, 'END.' || ???????);
   END;
   PROCEDURE proc_2 IS
   BEGIN
      api_log.trace_data(sysdate, 'START.' || ???????);
      proc_1;
      api_log.trace_data(sysdate, 'END.' || ???????);
   END;
END; I would like to replace "???????" with a function which would return a name of called procedure, so result of trace data after calling TEST_PACKAGE.proc_2 would be:
   11.1.2013 09:00:01    START.*TEST_PACKAGE.proc_2*
   11.1.2013 09:00:01    START.*TEST_PACKAGE.proc_1*
   11.1.2013 09:00:01    END.*TEST_PACKAGE.proc_1*
   11.1.2013 09:00:01    END.*TEST_PACKAGE.proc_2*I tried to use "dbms_utility.format_call_stack" but it did not return the name of procedure/function.
Many thanks,
Tomas
PS: I don't want to use an hardcoding

You've posted enough to know that you need to provide your 4 digit Oracle version (result of SELECT * FROM V$VERSION).

I usually use this method
1. Create a SQL type for logging information
2. Put the package name into a constant in the package spec
3. Add a line to each procedure/function for the name.

Need Help: Using Ref Cursor in ProC to call a function within a Package

I'm calling a function within a package that is returning a REF CURSOR.
As per the Oracle Pro*C Programmer's Guide, I did the following:
1) declared my cursor with a: EXEC SQL BEGIN DECLARE SECTION and declared the cursor as: SQL_CURSOR my_cursor;
2) I allocated the cursor as: EXEC SQL ALLOCATE :my_cursor;
3) Via a EXEC SQL.....END-EXEC begin block
I called the package function and assign the return value to my cursor
e.g. my_cursor := package.function(:host1, :host2);
Now, the only difference between my code and the example given in the Pro*C Programmer's Guide is that the example calls a PROCEDURE within a package that passes back the REF CURSOR as an OUT host variable.
Whereas, since I am calling a function, the function ASSIGNS the return REF CURSOR in the return value.
If I say my_cursor := package.function(:host1, :host2); I get a message stating, "PLS-00201: identifier MY_CURSOR" must be declared"
If I say :my_cursor := package.function(:host1, :host2); I get a message stating, "ORA-01480: trailing null missing from STR bind value"
I just want to call a package function and assign the return value to a REF CURSOR variable. There must be a way of doing this. I can do this easily in standard PL/SQL. How can this be done in Pro*C ???
Thanks for any help.

Folks, I figured it out. For those who may face this problem in the future you may want to take note for future reference.
Oracle does not allow you to assign the return value of a REF CURSOR from a FUNCTION ( not Procedure - - there is a difference) directly to a host variable. This is the case even if that host variable is declared a CURSOR variable.
The trick is as follows: Declare the REF CURSOR within the PL/SQL BEGIN Block, using the TYPE statement, that will contain the call to the package function. On the call, you then assign the return REF CURSOR value that the function is returning to your REF CURSOR variable declared in the DECLARE section of the EXEC SQL .... END-EXEC PL/SQL Block.
THEN, assign the REF CURSOR variable that was populated from the function call to your HOST cursor varaible. Then fetch this HOST Cursor variable into your Host record structure variable. Then you can deference individual fields as need be within your C or C++ code.
I hope this will help someone facing a deadline crunch. Happy computing !

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.

How do I view a FUNCTION within a Package Body

I can see the FUNCTION being executed within the Package...
FUNCTION Stop_Refresh_AsBilled
RETURN Number;
And within Oracle SQL Developer and using the Connection and "Packages" part of the Schema, I see the Function Name. However, when I <Double-Click> on the FUNCTION Name within the Schema, it is taking me to where the FUNCTION is executed within the Package and NOT to the PL/SQL Code that actually makes up the FUNCTION.
Am I missing something here??? Maybe in my Preferences??? How can I drill down further to actually find the FUNCTION Definition and PL/SQL Code that makes up the FUNCTION within the Package Body???
I can bring up the Package Body and Search on the FUNCTION that way. I'm hoping there is an easier way however to drill down to the actual PL/SQL Code that makes up the FUNCTION.
I hope I am being clear in my explanation here.
Thanks for your review and I am hopeful for a reply.

Jim, opening the body node to see all functions and procedures sometimes does not work in 3.0
I have many packages generated by Feuerstien's CodeGen utility. The Query package appears just fine with every function and procedure appearing as expected in both header and body nodes. However, the Change Package fails miserably. Header shows all functions and procedures fine, but the body node only shows the top private declarations of variables and types. Not one function or procedure appears in the expanded node.
The only thing I can figure is that the Change package of about 30 named items has many of the same name+ with overloaded parameters. I think SQL Dev is having problems parsing the names in the body even though it does fine with the names in the header of the package--perhaps because of many private variables and PRAGMA's declared at the top of the body.
Both packages have about 30 functions, but the Change package body has over 2000 lines while the Query package has fewer than 500.
Just adding to the mystery--but I think it merits a bug report (gotta figure out where to report it now).

Calling oracle function defined within package from JPA

Hi All,
I am trying to call a function get_owner() defined under a package pkg_x_y.
But I get an error when I do
entityManager.createNativeQuery("call pkg_x_y.get_owner()");
Caused by: java.sql.SQLSyntaxErrorException: ORA-00907: missing right parenthesis
What is the correct way to execute this function?
Thanks in advance.

JPA 2.1 standardized stored procedure support, and is available within EclipseLink 2.5 as described here: http://wiki.eclipse.org/EclipseLink/Release/2.5/JPA21#Stored_Procedures
If you are unable to use JPA 2.1, you can use EclipseLink's stored procedure support as described here: http://wiki.eclipse.org/EclipseLink/Examples/JPA/StoredProcedures
The problem you are getting with your call though might be coming from within the stored proc itself, not the native query execution. Its hard to tell - are you able to execute the query on your database directly, such as through SQLPlus?

Tricky: Calling Oracle Function in an Package with DAO over ODBC

Hello,
our customer is using Oracle 10.2.0.3 Enterprise Edition. We've to create an interface from our Microsoft Access 2000 application to the oracle system.
We want to call a Oracle Package-Function with DAO over ODBC.
We are using VBA with Microsoft Access 2000 SP3.
The ADO solution that works is:
Public Function CallSProcADO()
Dim cmd As ADODB.Command
Dim cmdWrite As ADODB.Command
Dim conn As ADODB.Connection
Dim param As ADODB.Parameter
On Error GoTo err_handler
Set conn = New ADODB.Connection
conn.Open "dsn=xxx;UID=xxx;PWD=xxx;"
Set cmdWrite = New ADODB.Command
cmdWrite.ActiveConnection = conn
cmdWrite.CommandText = "{ ? = call XXX.PACKAGENAME.FUNCTION(?,?)}"
cmdWrite.Parameters(0).Direction = adParamReturnValue
cmdWrite.Parameters(0).Type = adInteger
cmdWrite.Parameters(1).Direction = adParamInput
cmdWrite.Parameters(1).Type = adVarChar
cmdWrite.Parameters(1).Value = "C0045/2006"
cmdWrite.Parameters(2).Direction = adParamInput
cmdWrite.Parameters(2).Type = adVarChar
cmdWrite.Parameters(2).Value = "J"
cmdWrite.Execute
conn.Close
MsgBox "Successfull!"
Exit Function
err_handler:
MsgBox "Error!"
End Function
Now we want to know if it's possible to use DAO to do the same.
best regards
Arndt

During binding, strings are generally skipped. As such, you should first try replacing XMLType('?') with XMLType(?). You don't need to specify '?' because the system knows the proper type from your SQLBindParameter call.
Also, you should try replacing:
sr = SQLBindParameter(hstmt, 3, SQL_PARAM_INPUT, SQL_C_CHAR, SQL_LONGVARCHAR, 0, 0,(SQLPOINTER)3, 0, &type[2]);
with
sr = SQLBindParameter(hstmt, 3, SQL_PARAM_INPUT, SQL_C_CHAR, SQL_LONGVARCHAR, 0, 0,(SQLPOINTER)buf, BUFSIZE, &type[2]);

Hi,
Welcome to the forum!
You'll find that there are a lot of people willing to help you.
Are you willing to help them? Whenever you have a problem, post enough for people to re-create the problem themselves. That includes CREATE TABLE and INSERT statements for all the tables you use.
Error messages are very helpful. Post the complete error message you're getting, including line number. (It looks like your EXCEPTION sections aren't doing much, except hiding the real errors. That's a bad programming practice, but probably not causing your present problem - just a future one.)
Never post unformatted code. Indent the code to show the extent of each procedure, and the blocks within each one.
When posting formatted text on this site, type these 6 characters:
\(all small letters, inside curly brackets) before and after each section of formatted test, to preserve the spacing.
For example, the procedure find_test_called would be a lot easier to read like this:PROCEDURE find_test_called
IS
BEGIN
     BEGIN
          V_max := Manage_students.GET_LASTMT;
          DBMS_OUTPUT.PUT_LINE ('MAX_NUMBER :' || V_max);
     EXCEPTION
          WHEN OTHERS
          THEN
               DBMS_OUTPUT.PUT_LINE ('Error in finding student_id: ');
               RETURN      NULL;
     END;
     COMMIT;
EXCEPTION
     WHEN OTHERS
     THEN
          DBMS_OUTPUT.PUT_LINE ('Error in finding student_id: ');
END find_test_called;
It's much easier to tell from the code above that you're trying to return NULL from a procedure. Only functions can return anything (counting NULL); procedures can have RETURN statements, but that single word"RETURN;" is the entire statement.

Calling a function in apex region

Hi
I want to call a function from a package into Apex report region , but it wont the parse
i tested in sql dev successfully

SOR_OFFENDER.MIDDLE_NAME || ' ' ||
SOR_OFFENDER.LAST_NAME as "Name",
SOR_OFFENDER_DETAILS.get_offlu_url(:p216_detail) ---package where function is define
FROM SOR_OFFENDER,
SOR_LOCATION
WHERE SOR_OFFENDER.OFFENDER_ID = SOR_LOCATION.OFFENDER_ID
AND :p216_detail = SOR_LOCATION.OFFENDER_ID
any idea /help

I have to use this function to link other page or portal , using different parameter on different reports.
CREATE OR REPLACE FUNCTION
get_offlu_url (p_offender_id IN NUMBER) return VARCHAR2
     as
    temp_url_string varchar2(300);
    final_url_string varchar2(300);
    v_doc_num off_profile.doc_num%type;
    v_booking_id off_profile.offender_book_id%type;
    begin
       select http||server||port||dad||start_page into temp_url_string
        from offlu_url;
       select doc_num, offender_book_id into v_doc_num, v_booking_id
         from off_profile
         where offender_id = p_offender_id;
       final_url_string := temp_url_string||'doc_num='||v_doc_num||'&abc='||v_booking_id;
       return final_url_string;
    exception
       when too_many_rows then
           v_doc_num := 0;
           v_booking_id := 0;
    END get_offlu_url;

Invoke a function in a package

I need to call a function in a package that will return back to
me the database I am connected to
The package and function is called :p_common.sf_get_dbname
CallableStatement getDBName=null;
ResultSet rs2=null;
         try
              ggetDBName = con.prepareCall("{call ? := P_COMMON.SF_GET_DBNAME()}");
               getDBName.registerOutParameter(1, OracleTypes.CURSOR);
               getDBName.execute();
               rs2 = (ResultSet) getPxCcy.getObject(1);
               String db = rs2.getString(1);
               logger.info("DB connected to is " + db);
I am not getting the correct dbname? is the above way to do the correct way?

Call function in the package ....

I have interesting problem. It's interesting because it works on one server and does not work on another, both servers are ORACLE 10.2.0.2 on Solaris 10, both have identical users.
when I call pkg_utilities_public.GET_CURRENT_POST_DATE (sysdate) I get correct result on one server and error ORA-00904: "PKG_UTILITIES_PUBLIC"."GET_DATE": invalid identifier on the other, I have a user with DBA rights ...
what's even more interesting that I can compile this on both servers with no issue
the issues is how I call GET_DATE, I call it as GET_DATE instead of PKG_UTILITIES_PUBLIC.GET_DATE (lazy way but still should work on both) any idea why this works on one server and not the other? If I call it with PKG_UTILITIES_PUBLIC.GET_DATE it works on both, so I have solution, but I'm wondering why the first thing does not work.
CREATE OR REPLACE PACKAGE FDM.PKG_UTILITIES_PUBLIC AUTHID CURRENT_USER IS
--- GETS DATE BASED ON PERIOD_KEY (return YYYYMMDD or YYYYMM)
FUNCTION GET_DATE (v_period_key number:= 0) RETURN NUMBER ;
--- if today is post_dt get today, if not get previous post date
FUNCTION GET_CURRENT_POST_DATE(v_date DATE) RETURN DATE;
END;

AND PERIOD_DT = TRIM(v_date);
RETURN v_output_dt;
END;

speaking technical and not personal, I think this is related to serilization of SQL engine from PLSQL engine,
both samples below work on SERVER A,
sanple 1 does not work on server B, sample 2 works on server B (you can see I removed the call from SQL into PLSQL (this is generally better approach).
FUNCTION GET_CURRENT_POST_DATE(v_date DATE) RETURN DATE IS
v_output_dt DATE;
BEGIN
SELECT TO_DATE(GET_DATE(DECODE( POST_DT_FLG,'Y',PERIOD_KEY,'N', PRIOR_POST_DT_KEY)),'YYYYMMDD')
INTO v_output_dt
FROM FDM.PERIOD
WHERE PERIOD_TYPE_CD = 'D'
AND PERIOD_DT = TRIM(v_date);
RETURN v_output_dt;
END;
FUNCTION GET_CURRENT_POST_DATE(v_date DATE) RETURN DATE IS
v_output_dt DATE;
v_my_date NUMBER;
BEGIN
SELECT DECODE( POST_DT_FLG,'Y',PERIOD_KEY,'N', PRIOR_POST_DT_KEY)
INTO v_my_date
FROM FDM.PERIOD
WHERE PERIOD_TYPE_CD = 'D'
AND PERIOD_DT = TRIM(v_date);
v_output_dt := TO_DATE(GET_DATE(v_my_date ),'YYYYMMDD');
RETURN v_output_dt;
END;

Call outside function with same name in a package

I created a function as follows:
create or replace function f1 return number
is
begin
return 1;
end;
This f1 is to be called in a package created below.
Then I create a package with a function in it, as follows:
create or replace package pack1 as
function f1 return number;
end;
Now I define the package body as follows:
create or replace package body pack1 as
function f1 return number as
-- I am trying to call the first function f1 defined above here
How do I resolve the name issues here?
In other words, I want to call a function with the same signature outside a package.
Thanks for your kind help.

Hi,
Welcome to the forum!
Do you have a good reason for using the same name?
Refer to the stand-alone function with the owner name, even though it's your current schema.
That is, even if the package and the stand-alone function are owned by scott, in the package, say
x := scott.f1;

Call a function in a package body
