Executing procedure within same procedure

Hi all,
Can any one tell me what would be happen if execute procedure within same procedure.
Example :
create or replace procedure print(str in varchar2)
is
begin
print(str);
dbms_output.put_line(str);
exception
when others then
null;
end print ;
Regards,
P Prakash

But, you could call the same procedure in recursion procedure.
This kind of procedure has :
1) action of the recursion procedure
2) condition to go out from the same recursive procedure
SQL> create or replace procedure print(str in varchar2) is
2      num_letters natural;
3      string_tmp varchar2(50);
4 begin
5      -- recursion action
6      dbms_output.put_line(str);
7
8      -- recursion condition
9      num_letters := nvl(length(str), 0);
10      if num_letters > 0 then
11          print(substr(str, 1, num_letters - 1));
12      end if;
13 end print;

Execute both 32-bit and 64-bit external procedures within same DB

Hi,
I have a 64-bit installation of oracle9i.
I want to know if it is possible to execute both 32-bit and 64-bit external procedures within the same database. If yes, can you please help on how I can do it?

Thanks. The reason I was thinking of doing this is we have a lot of existing apps which are already configured for a particular name. We are moving to a 64-bit OS and have found that some apps must remain 32-bit while others must be upgraded
to 64-bit (all related to 3rd party code availability). There are a lot of config files (because of a lot of apps on multiple servers). So either bite the bullet and update all the configs to use new names or "cheat" and have both 32 and 64 bit
DSNs use the same name.

Executing Command within Pkg.procedure does not work-but command line does

[Version 10.2.0.2
[Scenario] Let's say my Username is Jack. My goal is to grant two roles to a user. From the command line, I have no problem.
PROMPT-> Grant role1,role2 to TESTUSER
However, when I create a package and procedure (owned by Jack); I receive an ORA-01919 error saying that role2 does not exist.
There is no question the role exists and I am able to grant it to the TESTUSER on the command line as Jack.
Any ideas what is going on?

I can't post it as the database is on another system. However, I found my the fix. My Jack user had grant any role; therefore, I thought it should work both from command line and package.proc; however I granted role2 to Jack with admin privs and it works now both from the command line and the pkg.proc.
Thanks for the response.

Calling package procedure within another procedure ???

Hello ,
I have package called import_pack, within this i have procedure called import_proc. I have another separate procedure called main_proc.
Now i want to call import_proc in main_proc. how do i do this ???
Any example would be great. Thank you so much.

Hi,
If the import_pack package is in the user_x schema, then the following will always work:
user_x.import_pack.import_proc (...);If main.proc is also in the user_x schema, then the owner name is optional, so this would be acceptable, too:
import_pack.import_proc (...);If main_proc is in the same package, then the package name is optional, so this would also work:
import_proc (...);

Running unix commands from within a procedure

Oracle 11.1, AIX 6.1
================
A developer would like to know what the commands are to execute from within a procedure to run unix commands on the database server and capture those results back to the procedure for parsing & manipulation.
Thanks.

Don't take this as the correct way to do it, but this is merely 'a' way to do it:
have a db procedure thats executes a db function
create or replace procedure csproc(p_cmd in varchar2)
as
x number;
begin
x:=csfunc(p_cmd);
dbms_output.put_line('x is: '||x);
end;
/The function calls a piece of java to execute the os command and return the return code of the os command
create or replace function csfunc( p_cmd in varchar2) return number
as language java
name 'csclass.RunThis(java.lang.String[]) return integer';
/Here is the java class to run the os command
create or replace and compile java source
named "csclass"
as
import java.io.*;
import java.lang.*;
public class csclass extends Object
public static int RunThis(String[] args)
   Runtime rt = Runtime.getRuntime();
    int        rc = -1;
    try
       Process p = rt.exec(args[0]);
      int bufSize = 4096;
       BufferedInputStream bis =
       new BufferedInputStream(p.getInputStream(), bufSize);
       int len;
       byte buffer[] = new byte[bufSize];
       // Echo back what the program spit out
       while ((len = bis.read(buffer, 0, bufSize)) != -1)
          System.out.write(buffer, 0, len);
       rc = p.waitFor();
    catch (Exception e)
       e.printStackTrace();
       rc = -1;
    finally
       return rc;
/and finally the os command - in this case its a very simple shell script
#!/usr/bin/ksh
echo "Hi" >> /app/oracle/workdir/cs.logwill have to grant privileges to my user 'CS' to run the various os commands

Procedure within procedure problem

Hi
I have a table of 5 different magazines and a table of purchases of those magazines. I have written a procedure to take the details of a given magazine and place the sales for a given month into a sales table as follows:
create or replace procedure monthly_sales(mag number, startdate date, enddate date) is
magtotal number(7,0);
magprice magazine.unitprice%type;
magsales number(7,2);
begin
select count(p.magid), m.unitprice into magtotal, magprice from purchase p, magazine m where p.datepurchased between startdate and enddate and p.magid = mag and m.magid=p.magid
group by m.unitprice;
magsales := magtotal*magprice;
insert into sales values(startdate, mag, magtotal, magsales);
end;
What I would like to do though is have a procedure that you just need to run once and it will enter the sales for a given month for all magazines into the sales table. My thought was to try to do this using procedures within a procedure as follows:
create or replace procedure monthly_sales(startdate date, enddate date) is
magtotal number(7,0);
magprice magazine.unitprice%type;
magsales number(7,2);
procedure mag1 is
begin
select count(p.magid), m.unitprice into magtotal, magprice from purchase p, magazine m where p.datepurchased between startdate and enddate and p.magid = 1 and m.magid=p.magid
group by m.unitprice;
magsales := magtotal*magprice;
insert into sales values(startdate, 1, magtotal, magsales);
end mag1;
procedure mag2 is
begin
select count(p.magid), m.unitprice into magtotal, magprice from purchase p, magazine m where p.datepurchased between startdate and enddate and p.magid = 2 and m.magid=p.magid
group by m.unitprice;
magsales := magtotal*magprice;
insert into sales values(startdate, 2, magtotal, magsales);
end mag2;
procedure mag3 is
begin
select count(p.magid), m.unitprice into magtotal, magprice from purchase p, magazine m where p.datepurchased between startdate and enddate and p.magid = 3 and m.magid=p.magid
group by m.unitprice;
magsales := magtotal*magprice;
insert into sales values(startdate, 3, magtotal, magsales);
end mag3;
procedure mag4 is
begin
select count(p.magid), m.unitprice into magtotal, magprice from purchase p, magazine m where p.datepurchased between startdate and enddate and p.magid = 4 and m.magid=p.magid
group by m.unitprice;
magsales := magtotal*magprice;
insert into sales values(startdate, 4, magtotal, magsales);
end mag4;
begin
select count(p.magid), m.unitprice into magtotal, magprice from purchase p, magazine m where p.datepurchased between startdate and enddate and p.magid = 5 and m.magid=p.magid
group by m.unitprice;
magsales := magtotal*magprice;
insert into sales values(startdate, 5, magtotal, magsales);
end;
However, when I run this it is ignoring all the procedures within the main procedure and just entering the results for magazine 5. I'm at a loss as to why this isn't working, is this even the correct way to go about it? any help would be greatly appreciated
thanks

Why doing it the hard way?
A single insert statement will do the trick.
I made a bit of a guess as to the structure of your tables:
create table magazine (magid number primary key, unitprice number);
create table purchase (magid number references magazine(magid), datepurchased date);
create table sales (startdate date, magid number references magazine(magid), magtotal number, magsales number);
insert into magazine(magid, unitprice) values (1, 3.95);
insert into magazine(magid, unitprice) values (2, 4.95);
insert into magazine(magid, unitprice) values (3, 3.50);
insert into magazine(magid, unitprice) values (4, 6.0);
insert into magazine(magid, unitprice) values (5, 5.50);
insert into purchase(magid, datepurchased) values (1, sysdate);
insert into purchase(magid, datepurchased) values (1, sysdate);
insert into purchase(magid, datepurchased) values (2, sysdate);
insert into purchase(magid, datepurchased) values (2, sysdate);
insert into purchase(magid, datepurchased) values (2, sysdate);
insert into purchase(magid, datepurchased) values (4, sysdate);
insert into purchase(magid, datepurchased) values (5, sysdate);
insert into purchase(magid, datepurchased) values (5, sysdate);
insert into purchase(magid, datepurchased) values (5, sysdate);
insert into purchase(magid, datepurchased) values (5, sysdate);
commit;
create or replace procedure monthly_sales(p_startdate in date, p_enddate in date)

insert into sales (startdate, magid, magtotal, magsales)
    select p_startdate
    ,      p.magid
    ,      count(p.magid)

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;

Using 2 refcursors within the same procedure

Hi,
Can we use 2 refcursors within the same procedure. This might sound strange. But I have a scenario of doing so- one for dynamically checking for some validations and another for returning a result set.

Yes, go thru the below example.
CREATE OR REPLACE PACKAGE CURSPKG AS
TYPE T_CURSOR IS REF CURSOR;
PROCEDURE OPEN_TWO_CURSORS (EMPCURSOR OUT T_CURSOR,
DEPTCURSOR OUT T_CURSOR);
END CURSPKG;
CREATE OR REPLACE PACKAGE BODY CURSPKG AS
PROCEDURE OPEN_TWO_CURSORS (EMPCURSOR OUT T_CURSOR,
DEPTCURSOR OUT T_CURSOR)
IS
V_CURSOR1 T_CURSOR;
V_CURSOR2 T_CURSOR;
BEGIN
OPEN V_CURSOR1 FOR SELECT * FROM EMP;
OPEN V_CURSOR2 FOR SELECT * FROM DEPT;
EMPCURSOR := V_CURSOR1;
DEPTCURSOR := V_CURSOR2;
END OPEN_TWO_CURSORS;
END CURSPKG;
I hope it would be helpful.

EXECUTE IMMEDIATE within Procedure doesn't work!!

Hi,
I have a code in which the procedure is successfully created, but when I try to check if the table TEST_TABLE is created (ex, DESC TEST_TABLE) it generates an error:
ORA-04043: object TEST_TABLE does not exist
Which means that my EXECUTE IMMEDIATE didn't work within the procedure for some reason, while it works perfectly alone without the procedure!!
Hope you help me with this..
Here's the my code:

AS
BEGIN
EXECUTE IMMEDIATE ' CREATE TABLE TEST_TABLE (ITEM_DESC VARCHAR2(10))';
END;
--Procedure created.
DESC TEST_TABLE

Can you tell me how to use INSERT with EXECUTE IMMEDIATE.
Thanks :)Just as an FYI, this is really not a good methodology to program in Oracle. If you're doing this for purely learning purposes then it's less 'bad', but if you plan on programming as a career in Oracle, this isn't the method you'd want to adopt (i'll not say there is NEVER a case for something like this, but it's a small percentage of the typical use cases).
You would do better to create a global temporary table if you need a table to muck around with in a session, or create a permanent table (likely not via procedures) and have it persist in the schema of your choice.
Utilizing execute immediate for insert statements, especially without BIND VARIABLES, will create a sad day for your database.

Calling a stored procedure within a package

We have a number of packages containing stored procedures. In an existing production application, we used embedded SQL in C programs to call these stored procs
e.g.
EXEC SQL EXECUTE
BEGIN owner.fees_calc.some_fee(:parm1,...);
END;
END-EXEC;
Now, I am trying to use SQLJ to call this same stored proc in the package. However, I am getting a compilation error from sqlj saying that it cannot find a stored procedure or function of that name. It works fine if I use a stored proc that is not in a package.
So how do I call a stored procedure within a package? Or is this not currently possible with sqlj?
I am also getting a warning just before the error and I'm wondering if the error is being caused by this:
Warning: You are using an Oracle JDBC driver, but connecting to a non-Oracle database. SQLJ will perform JDBC-generic SQL checking.
I am connecting to an Oracle 7.3.3 database using an Oracle 7.3.4 JDBC driver. I also tried using the Oracle 8.0.5 JDBC driver for the same database but I get the same warning message.

I used the following code to call a stored
procedure via SQLJ:
try {
#sql [iCtx] {
CALL ibs.cvs_validate.validate_port_id(:IN record_id ,:IN poe_pod_flag,:IN port_id,:OUT error_code,:OUT error_message) };
where
"ibs" is the schema
"cvs_validate" is the package
"validate_port_id" is the procedure
The code runs fine, but to get it to compile
in JDeveloper 2.0, I had to disable the "Check SQL semantics against database schema" option on the Project Properties (SQLJ) property sheet.

How to call multiple stored procedure from same DB Adapter

Hi,
I want to invoke 3 stored procedures from my message flow in BUS . I created a DB adapter and invoked 1 successfully . Now I don't to configure 2 other DB adapters for calling other 2 stored procedures . I want some how to be able to call the other 2 from the first DB adapter only . Somehow I need the flexibility to have procedure names as the operation names in 1 wsdl and be able to configure this in JDeveloper for this at time of DB adapter configuration . I am using 11G . Is it possible ?

You can probably create a DB adapter with operation type selected as Execute Pure SQL and write SQL code to invoke the stored procedures depending on the procedure name (which you can get as one of the parameters of DB Adapter).
However, Even if you were able to do it, the DB Adapter schemas are generated based on stored procedure parameter list and types. If you use Execute Pure SQL type of DB Adapter the schema will be generated based on the parameters which you are using in your custom SQL code within DB Adapter. Which means that if you want to add a new stored procedure as target which has a different name and different parameters then you will need to regenerate the DB adapter and update your custom SQL code. This also means that you will need to do regression testing interfaces to all stored procedures whenever there is any change in this DBAdapter.
Now, my question is why do you want to invoke multiple stored procedures from same DB adapter?
This is not a good way to design integration solutions and makes your services resistance to change as it will take more time to change and test.
If all that you want is to have a web service which can have different operations for different stored procedures then you should create three business services and create a wrapper proxy service which has one operation for each stored procedure, within the proxy transform and call the correct backend service (you can use operational branch). This way you have a modular code where each module (read interface to one stored procedure) can be independently modified and tested.

Using stored procedures within Crystal Reports

Hello all,
Background Information:
I am trying to teach myself how to execute a stored procedure within Crystal Reports. This is an aspect of Crystal that my work group has not utilized before and we're trying to gather information on the subject. We use Oracle to create and execute functions and procedures all the time, but I've never tried this within Crystal.
I use the "Add Command" functionality within Crystal on most of my reports so that I can taylor the sql to the report. I find this easier to do versus using the ODBC connection to the tables and writing the code through the Crystal Reports wizard. I also frequently use functions within these sql statements that are inserted in the Add Command.
What I'm trying to achieve:
I have a report that needs to run as a "trial", and then later as a committed "run". This is for a monthly billing system. Essentially, the user will run the report as the "trial", preview the data, make any necessay corrections, and then later, run the actual billing run. Within my application, the bills are not actually marked as "billed" until they are actually "billed', if that makes sense. As a result, the "trial" report will need to mark the bills as "billed", generate the report, and then rollback the data (so that the bills are not "billed". Once the actual billing reports are ran, the same report will run, but with a "commit" at the end of the report so that the bills are now "billed".
I'm trying simple tests and failing (i.e. taking baby steps to learn what capabilities Crystal has):
I created as simple of a procedure as I can envision. This procedure inserts the word "test" in one of my fields for a provided account number. When I try to run this procedure via Crystal (via New Report ->History->My ODBC Database link->Stored Procedures), Crystal asks for the account number parameter, as it should. But I then receive the error message:
Database Connector Error: '42000:[Microsoft][ODBC driver for Oracle]Syntax error or access violation'
The existing ODBC connection has work great for years and years to retrieve data from tables, but this is the first time I've tried to utilize procedures. Can anybody help? And can anybody explain what the Stored Procedures link is supposed to do? Am I going down the right path?
thanks,
Noel

Hello,
Make sure the Oracle client install path is in the PATH statement. And also make sure you are using an IN/OUT cursor. CR only reads the last SELECT statement. Search the Documents area on how to create a Stored Procedure.
Also, if you are using CR XI ( 11.0 ) then upgrade to CR XI R2 and apply all service packs ( SP 6 ). Go to this link: http://www.sdn.sap.com/irj/boc and download the trial version of CR XI R2 and use your XI keycode, then apply the patches which you can get to by clicking on the BusinessObjects tab above, then Downloads.
Direct link to the Trial version: http://www.sap.com/solutions/sapbusinessobjects/sme/freetrials/index.epx
It may fix your issue also.
Thanks again
