How to call a PL/SQL procedure from Portal

Env.Info: Windows NT Server 4 (Service Pack 3) / Oracle 8i R3 EE / Oracle Portal 3.0 Production.
I created a new schema "BISAPPS" and created a user with the same name. Ran provsyns.sql script to grant Portal API access. Created a new package under this new schema and compiled it against the database. After that I registered the schema as a portal provider. There were no errors.
Now I logged into Portal using the account PORTAL30. Refreshed the portlet repository and the new portlets appeared. I added the new portlet to the page. It is displayed successfully.
New portlet allows the user to enter a bug-number and lets the user to either view or edit. If the user clicks on the button "Edit", it opens a new window and displays the contents from BugDB application. But if the user clicks on "Show", it should display the output generated by a PL/SQL procedure (Owned by the above New Schema - BISAPPS) in a separate window. But instead it is displaying the following error in the separate window:
bisapps_pkg.buginfo: PROCEDURE DOESN'T EXIST.
DAD name: PORTAL30
PROCEDURE : bisapps_pkg.buginfo
URL : http://host_name:80/pls/portal30/bisapps_pkg.buginfo
And list of environment variables ....
Can anyone help me? How can I call a PL/SQL procedure when the button is clicked? Thanks in advance.

You must grant EXECUTE privilege on your procedure to the PORTAL30_PUBLIC user. If the error still persists, create a PUBLIC synonym for your procedure.

Error while calling java in sql

hi..
i would like to load and call simple java into oracle database. this is my simple java code.
public class SimpleJava {

System.out.println("Here we are");
then, i created .class file and ready to be loaded into oracle database using loadjava utility. i already loaded it successfully into a database. but, when i use pl/sql to call it in SQl*Plus, i got this error.... can anyone help me to solve this problem?

The first solution is to not do that in java in the first place.
DDL should be in script files which are applied to oracle outside of java.
Other than I believe there are some existing stored procedures in Oracle that take DDL strings and process them. Your user has to have permission of course. You can track them down via the documentation.

Calling a PL/SQL Package from a controller

Hi ,
I have to add some busines funtionality to the standard existing oco page .
i have extened the standard controller and add the validation logic there , now if the validation is true i have to call a pl/sql package to do some functions . now i am facing few issues here
a) can i call a pl/sql package from a controller ?
b) should i extend the standard AM and call the pl/sql package from the extended am . is extending am allowed ?
please let me know the best sol to achieve this

a) can i call a pl/sql package from a controller ?Yes you can call a pl/sql procedure from controller through OracleCallableStatement object.
 
b) should i extend the standard AM and call the pl/sql package from the extended am . is extending am allowed ?Extending AM is allowed, but as can achieve your goal through the CO extension, why bother to touch AM :)

I want to pass a cursor to a procedure as IN parameter.You can use the PL/SQL type called sys_refcursor - and open a ref cursor and pass that to the procedure as input parameter.
Note that the SQL projection of the cursor is unknown at compilation time - and thus cannot be checked. As this checking only happens at run-time, you may get errors attempting to fetch columns from the ref cursor that does not exist in its projection.
You also need to ask yourself whether this approach is a logical and robust one - it usually is not. The typical cursor processing template in PL/SQL looks as follows:
begin
open cursorVariable;
loop
 fetch cursorVariable bulk collect into bufferVariable limit MAX_ROWS_FETCH;
 for i in 1..bufferVariable.Count
 loop
 MyProcedure( buffer(i) ); --// <-- Pass a row structure to your procedure and not a cursor
 end loop;
 ..etc..
 exit when cursorVariable%not_found;
end loop;
close cursorVariable;
end;

Asynchronous web service call using PL/SQL

Hi Guys,
i'm using Apex 4.1.
Is that possible to invoke a web service asynchronously within PL/SQL code block ? If so,
How can i access the return value of the service when execution of that web service completes ?

Bolev wrote:
We have (Oracle 10g) automated process (ETL) based on internal data. Now there is an offer to incorporate existing web service call (let's say for additional record verification) in this process. Service call (I do not know what type of it yet) is using data from remote database which is not ours.Web service calls from PL/SQL is not that complex. You can use the standard UTL_HTTP package as shown in {message:id=4205205}.
I never heard anybody goes this way especially for ETL processes.Well, if you push a million rows through the ETL process and the call overhead for the web service call (assuming perfect network and web server response) is 1 sec, that translates into 277+ hours of runtime alone for the validation to be done via web service.
So yeah - it would seem kind of silly to use something like a web service to validate large volumes ETL data.

How to call a PL/SQL procedure from a Java class?

Hi,
I am new to the E-BusinessSuite and I want to develop a Portal with Java Portlets which display and write data from some E-Business databases (e.g. Customer Relationship Management or Human Resource). These data have been defined in the TCA (Trading Community Architecture) data model. I can access this data with PL/SQL API's. The next problem is how to get the data in the Java class. So, how do you call a PL/SQL procedure from a Java program?
Can anyone let me know how to solve that problem?
Thanks in advance,
Chang Si Chou

Have a look at this example:
final ApplicationModule am = panelBinding.getApplicationModule();
try
     final CallableStatement stmt = ((DBTransaction)am.getTransaction()).
                                                                                     createCallableStatement("{? = call some_pck.some_function(?, ?)}", 10);
     stmt.registerOutParameter(1, OracleTypes.VARCHAR);
     stmt.setInt(2, ((oracle.jbo.domain.Number)key.getAttribute(0)).intValue());
     stmt.setString(3, "Test");
     stmt.execute();
     stmt.close();
     return stmt.getString(1);
catch (Exception ex)
     panelBinding.reportException(ex);

How to call a PL/SQL procedure from a xml Data Template

We have a requirement in which we need to call a pl/sql package.(dot)procedure from a Data Template of XML Publisher.
we have registered a Data Template & a RTF Template in the XML Publisher Responsibility in the Oracle 11.5.10 instance(Front End).
In the Data Query part of the Data Template , we have to get the data from a Custom View.
This view needs to be populated by a PL/SQL procedure.And this procedure needs to be called from this Data Template only.
Can anybody suggest the solution.
Thanks,
Sachin

Call the procecure in the After Parameter Form trigger, which can be scripted in the Data Template.
BTW, there is a specialized XML Publisher forum:

This error message is very similiar to the message that Shanthir posted on Jan, 21. I did run the dbmslob.sql, but it doesn't help. Anybody has ideas how to solve it?
I used the PL/SQL web toolkit provided by OAS4.0.8.1. I believe oracle web agent is replaced by this toolkit.
Thanks,

Hi,
Glad that somebody else too got this problem. Well, as I had mentioned in my previous posting too, I think there are some procedures in the package, dbms_lob, like the writeappend, createtemporary etc.. which is not found in my dbms_lob.sql file, I am using 8.0.5, but I found these procedures in the 8i, I think it is becos of that.
By the way if anybody got this solution and got any workaround, please help me too.
I am still waiting for the solution to that.

SQL report region source to call a pl/sql function using DB link

Hi - I have a pl/sql function fn_dbtype(id NUMBER) defined in database X. The pl/sql function executes couple DML statements and returns a string (a SELECT query). I am able to call this function using SQL Plus (Connected to Database X) as below and it works fine:
declare
vSQL VARCHAR2(100);
begin
vSQL := fn_dbtype(1);
end;
The DML operations completed fine and vSQL contains the "Select" query now.
In APEX:
I am trying to create a SQL report in APEX using SQL query(PL/SQL function returning a sql statement) option. I am trying to figure out what to put in the region source so that the output of the "Select" query is displayed in the report.
Moreover APEX is hosted in a different database instance. So I would need to call this pl/sql function using a DB Link.
Please let me know what I need to put in the region source to execute the pl/sql function which returns the "Select" query thereby displaying the query output in the report. Thanks.

I want to know the step ( and/or the code) to be able to do so

It's suppose to return me a string.
I have the code to do it without the https part (easy!), but I want to have the way to do it https! :
vURL := 'http://207.253.66.69/frsq_dev/FRSQ_NIP_EXISTS?pNOM_NAISS=' || pNOM_NAISS || '&pPRENOM=' || pPRENOM || '&pNOM_MERE=' || pNOM_MERE || '&pSEXE=' || pSEXE || '&pDATE_NAISS_YYYY=' || pAn_naissance

IN operator is not working correctly while calling,although pl/sql procedur

CREATE or REPLACE PROCEDURE TEST(
idListCommaSeparated IN VARCHAR2
AS
CURSOR c_emp IS SELECT first_name,last_name,start_date From Employee where id IN(idListCommaSeparated);
r_emp c_emp%ROWTYPE;

insert into temp1 values('B',sysdate,sysdate,'A');
      open c_emp;
      loop
          fetch c_emp into r_emp;

             --business Logic
end loop;
      close c_emp;
end;
/idListCommaSeparated contains values like (2,3,4). while executing this procedure on sqlplus it is succefully created.
When i run the query separately on sqlplus
SELECT first_name,last_name,start_date From Employee where id IN(2,3,4)I got some rows in result.
why i am not getting via procedure correct result.
and one more thing the number of elements in 'idListCommaSeparated' values are not fixed,sometimes it may be(2,3,4) or sometimes variable value may (2,3,5,6).
I am not able to understand,where i am going wrong?

see whether you find nested table parameter implantation option useful. Also supported by .net/java in case that's your calling appln.
Below is plsql block having a procedure with input paramater of empid's. It returns a cursor( empno and ename) as out parameter.
The empid's are hardcoded in the calling block.

Calling a PL/SQL from VB with IN argument of object type

I need to call a PL/SQL function in Oracle 8.1.6 from VB. One of the IN arguments is an object type (TYPE). How would I instantiate the variable of Oracle object type on VB side so that it can be passed to the Oracle?
Thank you

You have some flaws in your code.
First - don't use same identifier for pl sql variables ( including parameters) and column names. In your case oracle will evaluate the where clause as where column_name=column_name which is probably not what you want. The next one - you should ensure that select into yields one row , not more, not less, otherwise you 'll run into exception.
To actually print the desired values, you have to use dbms_output aware client ( sqlplus is such one) and for sqlplus in particular you have to issue set serveroutput on
Here is a very basic example how can you get it to work:

Calling a PL/SQL function in the SQL statement

I have a PL/SQL function which i should call in a SQL statement.
Let's say the function is func1(parameter1,parameter2),
it should be called like this :- SELECT func1() FROM mytable ;
Can any one help me out on this ?
---Thanx in advance

you can call pl/sql functions from pl/sql using
select fn1('param1','param2') from table;
if you dont want to pass paramters, you have to specify default
value while creating function like below
create function fn1(p1 number default null,p2 varchar2 default
null) return...
now you can call using
select fn1 from table;

Call a PL/SQL procedure or function from applet

Could anyone please let me know how I could call a PL/SQL procedure
or function from a JDBC method from applet with Internet Explorer?

It depends from where you are calling your PLSQL routine. If it is SQL*Plus then you can use & (ampersand) with the variable to be input at run time.
If you are executing the PLSQL routine from another application (some front end application) then it's not possible. Because when a procedure is executing at server side, the front end application does not have control, and the control is only transfered back to front end application when the PLSQL routine either completes successfully or throws an exception.
In either case, you can not go back to the PLSQL routine.
In this case, what you can do is, write code in your front end application to get that variable value from user and then pass that value to PLSQL routine.
