How to call a procedure from within another procedure?

What's the syntax to call a procedure from within a procedure.
I have a procedure z(user_id IN number, ....)
then
procedure a (user_id IN number, ....)
procedure b (user_id IN number, ....)
procedure c (user_id IN number, ....)
I want to call procedure a, b, c from inside procedure z.
How would I do that?

Same way :
SCOTT@db102 SQL> create or replace procedure a (p1 in varchar2) is
2 begin
3     dbms_output.put_line (p1);
4* end;
SCOTT@db102 SQL> /
Procedure created.
SCOTT@db102 SQL> create or replace procedure z (par1 in number) is
2 begin
3     if par1 != 0 then
4             a ('This is proc a');
5     end if;
6* end;
SCOTT@db102 SQL> /
Procedure created.
SCOTT@db102 SQL> set serveroutput on
SCOTT@db102 SQL> exec z (1);
This is proc a
PL/SQL procedure successfully completed.

PL/SQL: Executing a procedure from within another procedure

Hello, I'm a newbie and I need help on how to execute procedures from within another procedure. The procedure that I call from within the procedure have return values that I want to check.
I tried: EXECUTE(user_get_forum_info(p_forumid, var_forum_exists, var_forum_access, var_forumname));
but I get the error message:
PLS-00103: Encountered the symbol "USER_GET_FORUM_INFO" when expecting one of the following::= . ( @ % ; immediate
The symbol ":=" was substituted for "USER_GET_FORUM_INFO" to continue.
And when I tried: EXECUTE(user_get_forum_info(p_forumid, var_forum_exists, var_forum_access, var_forumname));
I get the error message:
PLS-00222: no function with name 'USER_GET_FORUM_INFO' exists in this scope

The procedure USER_GET_FORUM_INFO exists. (don't understand why it says "no FUNCTION with name", it's a procedure I'm executing)

Regards Goran

you don't have to use execute when you want to execute a procedure (only on sql*plus, you would use it)
just give the name of the funtion
create or replace procedure test
as
begin
    dbms_output.put_line('this is the procedure test');
end test;
create or replace procedure call_test
as
begin
    dbms_output.put_line('this is the procedure call_test going to execute the procedure test');
    test;
end call_test;
begin
    dbms_output.put_line('this is an anonymous block calling the procedure call_test');
    call_test;
end;

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.

Help!How can I find the name of a calling procedure from within a procedure/function?

Is there anyway to find out the name of calling procedure(database) from within a database stored procedure/function? This is required for creating an auditing module.
Thanks,
Abraham
===========
email:[email protected]

You can use this query to get the procedure names that are calling your procedure.
SELECT name FROM all_Dependencies
WHERE upper(referenced_name) = 'YOUR_PROC_NAME'
In your procedure, you can get these values into a cursor and then use them one by one.
Hope this would help.

Lag when calling BLS Transaction from within another

Using MII 12.0.
In MII class, they told us a "best practice" was to check the "Reload Transaction after Execution" box in the configuration of a Transaction call within a BLS. The reasoning behind it was that should this not be checked, a previous result of that called BLS transaction would still be cached in memory and used instead of the newly assigned values from within your calling BLS.
Checking the "Reload transaction after Execution" box forces MII to reload that transaction when it is called.
In time analysis, what has been noticed is that there's a significant - up to 9 seconds - lag time when one BLS calls another BLS. On a time-sensitive operation, that is an eternity. That amount of overhead defeats any hope of using common code libraries.
Questions -
1. Is this a true "best practice", or is it one that adds unnecessary overhead to a BLS?
2. If the calling BLS executes 1 time - but is subject to be executed multiple times over a certain interval - is checking the Reload box of the BLS it is calling unnecessary?
3. Even if you pass new data each time you call that BLS, is it still going to use/return whatever data it has cached until the cache expires?
4. Is there another way to ensure that the called BLS uses the data you pass it (and returns the corresponding result set) without incurring the amount of overhead that we have noted?
Thanks

The version we're on is 12.0.6 Build 13, and moving to 12.1 (something I am not directly involved in). In this version, I'm not seeing the menu options you describe, so it's apparently in 12.1 or later.
The issue we are having if the "Reload transaction after execution" box is not selected is indeed caching of values.
For example -
BLS1 runs every 5 minutes
BLS2 is called from BLS1, and in this case, retrieves error log info from a table - a common module used by several BLS's.
BLS3 is also called from BLS1, and in this case, writes to an error log using information retrieved from BLS2 from within the execution of BLS1. BLS2 & BLS3's calls are in 2 separate sequences, one after the other.
If BLS2 & BLS3 DO NOT have the "Reload Transaction after execution" checked, each will run with whatever the cached data in memory is for them, even though inside BLS1 I am assigning values to the input of BLS1 to send to BLS2, and passing the returned data from BLS2 into BLS3. Unless it's checked, BLS2 & BLS3 would continue to be called, however, it would be with whatever data has been cached for them.
If that "Reload" switch is checked, it will reload each transaction & call it with whatever data is being passed.
This was mentioned in the MII class I was in also. This is a generalization, but the way they described it was being similar to how you might save a web page to your local PC, and that unless that page is refreshed & changed, that from that point on, every time you brought up your saved web page, it would always display the same values in it. They didn't go into great deal to explain the mechanics of it, but MII would only load it the first time it executed, and that unless you forced it (by checking the Reload switch), it would always execute using the same cached values no matter what you were passing.

How to call java class from pl/sql procedure ?

Hello everyone,
My query is..
There is one pl/sql stored procedure which is doing some business logic and storing data in some columns of one table, suppose the table name is 'ABC' .. and the rest of columns of table ABC are getting updated using java class. Now my problem is whenever I insert data in ABC using store proc.. i have to call that java class so that it will update the rest columns ( why java class for updating the columns in ABC is ..because that logic cant be done from pl/sql proc.. it has to be done using java )

Calling a procedure from within a procedure

Hi Guys,
I have created a package to base a form on. The package contains some procedures, one of which is an Update procedure which can be seen below. I have a procedure in another package that I am trying to call. Basically the second procedure is called to implement a constraint. However, I am unsure as to what I should pass into this procedure, as a package/procedure for basing a form on is different to what I have come across before.

I want to use this package to compare the new inputs on this to the existing ones (this is carried out by the procedure. I have tried using :new. but this is not accepted. If I leave in the EXCEPTION then i get no errors from the form, but it will not save any changes I make on the database. If I remove the EXCEPTION then I get an error from the form - FRM-40735 UPDATE-PROCEDURE trigger raised unhandled exception ORA-04098. I am pretty sure this is because I am not supplying the correct variables to the called procedure,

How to use dbms_Scheduler.Create_Job from within stored procedure?

Hello,
using 10g (10.1.0.2.0) on Windows 2000 I had problems to create scheduler jobs from within a stored procedure (see example below). What easily succeeds using anonymous blocks failed when calling from a stored procedure, due to ORA-27486. Only when I compile the procedure with invoker's rights the call to dbms_Job.Create_Job is successfull!? From my knowledge there is no difference between invoker's and definer's rights, if I compile and call with the same user, is there?
Does anyone know the reason for this behaviour or is it simply a bug?
Have a nice day.

-- Example start.

commit;
end;
exec sched1; -- This call fails with ORA-27486.
exec sched2; -- This call succeeds!
/* Cleanup.
exec dbms_scheduler.drop_job('TEST_JOB1', true);
exec dbms_scheduler.drop_job('TEST_JOB2', true);
drop table t;

Your example code ran without problems for me on 10.1.0.3.0 so it probably is a bug.

Create a text file output from within a procedure

I can output to a file from within SQL+ using the spool command but how do I do this from within a procedure?
I have got a table called ABC and want to output columns A and B to a new text file based on variables pased through when the procedure is run, the name of the text file should be generated from a sequence?
Any info appreciated.

Hi,
U can use UTL_File Package, But the only constraint is it will write the file only on the server m/c and not on the client m/c.

Calling external programs from within a Tomcat application

I've got a fairly complex existing Tomcat application (which is packaged and built as a .war file) which I'm trying to edit so that it calls a Perl script part way through the processing, which will generate an XML file used later on. I think I've worked out how to call external scripts from within Java, but at the moment when I try and access the application via Tomcat the application either hangs or bails out (I don't know which, as the log files unhelpfully don't give any error messages).
The code which is causing the problem looks like this:
System.err.println("Calling runtime...");
Runtime runtime = Runtime.getRuntime();
System.err.println("Executing process...");
Process process = runtime.exec("/path/to/ysearch.pl 'News' '\"search query\"' 'file");
System.err.println("Waiting for process...");
int exitVal = process.waitFor();
System.out.println("Exited with error code: " + exitVal);The code gets as far as "Executing process..", beyond that there is nothing in the log file so I presume the runtime.exec() call is where the problem is. I'm not interested in reading the output from the script (there shouldn't be any), so that's not an issue, and the permissions on it allow anyone to read or execute ysearch.pl so I don't think there's a problem in that area.
Does anyone have any suggestions which I could try to get this to work? I've only been using Tomcat for a week (I'm picking up on someone else's code) so I might have made a beginner's mistake. I'm using Tomcat 5 on Fedora Core 7, and Java 1.5.0_01 (I can't easily change any of those).

I'm not sure, but I thing that overhead caused by calling du cannot be big enough to matter even on older machines.
But, when calling du from Perl script you are also invoking shell, and this can be a little bit more 'heavy'.

Oracle JDBC did not support return a result set, if you are using Oracle 9i, you can use pipeline function, then using the TABLE() function the get the row.

Need help to call a simple function from within another function?

I created a movieclip which has a function in its one and only frame.
function testx() {
x = x+2};
This movieclip is in the main timeline (in its own layer).
In another layer on the timeline I have created a single keyframe with a button instance called myBtn
myBtn.onRelease = function() {
var x
x =2
testx(2);
trace (x);
What I want to do is call the function in the movieclip frame from the button press function. However, I can't seem to reference it properly.
Can anyone help me to basically call a simple function from within another function?

Yes am using CS4. Have saved it as CS3 now. Ok the file is somewhat complicated and what I am testing is not what I ultimately want to do but if I can pass that variable I can figure it out. In terms of describing the file I think the only parts of importance are what I put in my previous post (please let me know if there is something I should be telling you that I have missed). I am 99.9% sure that I am using the correct instance name.
Scene1 Layer3 Frame1 has the function call for the button.
myBtn.onRelease = function() {
var x
x = 2
testx(2);
trace (x);
Slideshow layer //Actions Frame1 has the function
function testx(x) {
x = x+2};
thank you so much for helping me.
