Dangers of calling restricted procedures from when-validate-item

As you'll all know, you cannot call the restricted procedure go_item from within the when-validate-item trigger.
I've read that it is possible to get round this utilising timers, and I have managed to get this working.
However, I cannot help but think such procedures must be restricted for a reason. Therefore, I'd like to know if there are any known problems that might arise from implementing timers to call restricted procedures?
Thanks
Matthew

Certain types of triggers can't call restricted procedures because there is internal navigation or validation going on during the trigger execution, and the restricted procedures could mess that up. However, when you use a timer, the restricted procedure doesn't execute until after the trigger has finished, so the internal navigation/validation is complete. Because of this, the timer technique is a safe one. If it's a non-repeating timer, it should have very little effect on network traffic and performance.

When-validate-item trigger restriction on open form or call form

W have when-validate-item trigger. I need to place a code here that will bring up a form when the "valid entry" on the item has been made. I am getting a frm-40737:Illegal restricted procedure COMMIT...
Code snippet on the procedure that I am calling from the when-validate-item:
IF :System.Form_Status = 'CHANGED' THEN
Commit_Form;
end if;
Call_Form ('MY_FORM', HIDE, NO_REPLACE, NO_QUERY_ONLY,'PARAM');
Is there a work-around. We also cannot use timers here.
Any help is appreciated?
TIA

Thanks Sudha, I tested and it worked with the key-next-item trigger.
The only thing though, I was told that the users will not use the enter key when they navigate out of the field, it is either clicking on an exit button or function key F4...so I am still stuck with the same problem.
This site is really helpful and I hope to receive more ideas.
Thanks!

Error when calling a procedure from my apex application

Hello.
I want to create a small APEX application that can configure asynchronous change data capture (distributed hotlog) on certain tables.
Basically, what the application should do is to simply create change tables. Everything else is set up as prerequisite.
My problem is that when I run the following script from schema apex_cdd (using sqldeveloper) , it works; but if I run it from my apex application by calling it when pressing a button as a pl/sql process, it doen't work.
BEGIN
apex_cdc.enable_table_capture
     (     i_owner => 'staging_cdcpub',
          i_change_table_name     => 'g_changeTable',
          i_change_set_name     => 'Source_changeSet',
          i_change_source          => 'orcl01_cs',
          i_source_schema          => 'My_src',
          i_source_table          => 'G',
          i_column_type_list     => 'STARTDATE DATE,STATUS CHAR(1),NAME VARCHAR2(10),ENDDATE DATE,DESCRIPTION VARCHAR2(255),ID NUMBER(8,0),VALUE NUMBER(10,2)'
END;
If I look in the trace file, i see that the error is:
CDCdebug:in ChangeTable.java enableDisabledTriggers: ORA-06550: line 1, column 8:
PLS-00201: identifier 'SYS.DBMS_CDC_SYS_IPUBLISH' must be declared
ORA-06550: line 1, column 8:
PL/SQL: Statement ignored
oracle.jdbc.driver.OracleSQLException: ORA-06550: line 1, column 8:
PLS-00201: identifier 'SYS.DBMS_CDC_SYS_IPUBLISH' must be declared
ORA-06550: line 1, column 8:
PL/SQL: Statement ignored
Other remarks:
- My procedure calls: sys.DBMS_CDC_PUBLISH.CREATE_CHANGE_TABLE.
- I gave the same rights that I gave for apex_cdc schema to flows_030200 and APEX_PUBLIC_USER schemas (just to see if it works), but it doens't.
Is APEX calling the procedure from another schema ?
Does anyone has an idea why this procedure crashes if called from APEX application, but works ok if called from the same schema APEX application runs on, but using SQLDeveloper ?
Any thoughts are appreciated.

The procedure apex_cdc.enable_table_capture i created myself with no authid mentioned explicitly, so it uses definer rights, by default.
BUt this procedure is simply a wrapper for sys.dbms_cdc_publish.create_change_table.
When I look on the security model for this sys.dbms_cdc_publish, i see it runs under invoker rights. (http://www.psoug.org/reference/dbms_cdc_publish.html).
The code is like this:
CREATE OR REPLACE PROCEDURE enable_table_capture
          i_owner               IN VARCHAR2,
          i_change_table_name     IN VARCHAR2,
          i_change_set_name     IN VARCHAR2,
          i_change_source          IN VARCHAR2,
          i_source_schema          IN VARCHAR2,
          i_source_table          IN VARCHAR2,
          i_column_type_list     IN VARCHAR2
     IS

Calling stored procedure from EJB in JSever

I have some trouble to call stored procedure from EJB deployed to JServer on Oracle8i (815).
I have been able to sucessfully test the stored procedure using thin client JDBC driver. But when I user the default connection in JServer, the stored procedure never got called. Is there any restriction of EJB in JServer?
Thanks
null

Thanks man! that was a great help. looks like i am almost there. i created those items t obe hidden.
now i am passing three parameters to the procedure. my url for that column value looks like this,
javascript:P65_PARTITION_ID=#PARTITION_ID#;P65_DBC=#DBC#;P65_FILE_ID=#FILE_ID#;doSubmit('Sku_Save');
the #DBC# parameter is a name of the person that has spaces(firstname lastname). i am getting a javascript error saying,
Line: 1
Char: 37
Error:Expected ';'
i see that char 37 is the space after firstname.
any idea how i should get rid of this error.
Also, as you have been very helpful, a question further beyond :). the above procedure will return a OUT varchar parameter. i guess i have to create another item for that. how do i read it and display just below my report as text.
Thanks Again!

Unable to call a procedure from inside a another procedure

Dear members
I am trying to call a procedure from inside an another procedure.Both the procedures are present within the same package.I am trying to call the second procedure just before the end of the first procedure.Both the procedures are compiling fine but the tables are not getting populated inside the second procedure.Also the DBMS_OUTPUT statements present in second procedures are not getting displayed.(I feel the second procedured is not getting called).

Calling a procedure from Dynamic Page

I am trying to call a procedure from a dynamic page. The procedure displays multi records from a table. I have created a procedure:
PROCEDURE process_student_request( p_primary_request in wwv_utl_api_types.vc_arr,
p_alternate_request in wwv_utl_api_types.vc_arr,
p_action in varchar2,
l_status in out varchar2);
When I hit the submit button on the dynamic page it does not execute the procedure and tries to open a new page. How do I get this to work?
Here is the text of the page:
<HTML>
<HEAD>
<TITLE>Example</TITLE>
</HEAD>
<BODY>
<FORM action="portal30.star_portal.process_student_requests" method="post">
<TABLE BORDER="0" WIDTH="100%" CELLPADDING="2" CELLSPACING="0" class="RegionBorder">
<TR>
<TD valign="top" align="left" width="40%"><FONT class="PortletText1">
<ORACLE>declare
row_num number := 1;
hold_row_num number;
hold_class_cd stars3.req.class_cd%TYPE;
begin
for c1 in (select A.start_yy, A.school, A.student_id, A.class_cd, B.name from stars3.course B, stars3.req A
where A.student_id = portal30.star_portal.get_session_variable('STUDENT_ID') and A.start_yy = '01' and
A.alternate_no = '0' and
B.start_yy = A.start_yy and
B.school = A.school and
B.class_cd = A.class_cd)
loop
hold_class_cd := c1.class_cd;
htp.p(lpad(to_char(row_num),2,'0'));
htp.p('<select name="p_primary_request">');
htp.p('<option value="' || c1.class_cd|| '">' || c1.name || '</option>');
row_num := row_num + 1;
htp.p('<BR>');
end loop;
htp.p('<input type="submit" name="p_action">');
end;
</ORACLE>
</BODY>
</FORM>
</TD>
</TR>
</TABLE>
</HTML>

Bob,
You have variables in your procedure like l_status, p_alternate_status which you do not have in the form. Are these IN or OUT variables ?
If these are IN variables, this proc will not work because you do not have any variable in the form. So from where does it get the values? There is not any default declared too. You have to explicitly define IN or OUT variables.
Have you also given execute permission to public ?

Calling a procedure from AM

Hi,
I am getting the following error while trying to call a procedure from AM. I have check and all the parameters are being passed correctly. Not sure why this is throwing error. Below is the error message.
oracle.apps.fnd.framework.OAException: java.sql.SQLException: ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'AbcPositionDetails'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
Any help is appreciated.
Thanks in advance
PK

You will get this error when you pass wrong number of arguments to a pl/sql procedure.
use named parameter binding like proc(a=>'value') to avoid this error.

Calling a Procedure from a Button? (REVISITED)

Hi All,
I once asked a question Re: Calling a Procedure from a Button? & that problem was resolved when i was working on the online ApEx.
On my application, requirements have changed a bit: I have one form based on two tables. One table contributes two fields (name & surname) to the form while the remaining fields are contributed by another table to make a total of 17 fields on the form.
My process is in such a way that a user enters an id number & clicks Search button, if the apllicant exists then both name & surname corresponding with the id number will be retrieved from the database. If the applicant does not exist then an error message will be displayed inline with the id number field. Here's the PL/SQL anonymous block to that:
DECLARE
vNAME APPLICANTS.name%TYPE;
vSURNAME APPLICANTS.surname%TYPE;
BEGIN
SELECT count(*)
INTO :P2_COUNT
FROM applicants
WHERE id_number = :P2_ID_NUMBER;
IF :P2_COUNT > 0 THEN
SELECT name,surname
INTO vNAME, vSURNAME
FROM applicants
WHERE id_number = :P2_ID_NUMBER;
:P2_NAME := vNAME;
:P2_SURNAME := vSURNAME;
ELSE
apex_application.g_print_success_message := '<span style="color:red">Applicant does not exist.</span>';
END IF;
EXCEPTION WHEN NO_DATA_FOUND THEN
apex_application.g_print_success_message := '<span style="color:red">Exception Caught.</span>';
END;The PL/SQL block works except for error displaying part (but that's a problem for another day).
NB: On my application, there’s already Automated Row Fetch & Automatic Row Processing (DML) processes for one table. Furthermore, there is also a javascript for verifying the validity of an id number. As a result, I decided to include Automated Row Fetch & Automatic Row Processing (DML) processes for the other table. When I click a Search button the javascript is activated even though I did not specify a URL target for the button - because this is a simple button among region items – it does not have Optional Url Redirect section.
I'm not sure what I'm doing wrong here - any help is appreciated.
Regards
Kamo

Hi Dan,
Sorry for causing confusion with my post - it's just that I was asking the same question (with different constraints) as I had asked before so I didn't feel like going to details was necessary because in my post I included a link to the previous thread. Interestingly, I was working on apex.oracle.com when I posted the original thread - the only problem came to be when I started to move the solution to my application on my machine.
Anyway, thanks for the response!

Curious thing while calling a procedure from Java !...

Hi !. My name is Agustin and my doubt would be the following one... I am working for a e-business comp and they asked me to call a procedure from java... The code is the following one:
CallableStatement cs = null;
System.out.println("Fecha Nro. 1: " + paramFechaDesde);
System.out.println("Fecha Nro. 2: " + paramFechaHasta);
try
cs = getDBTransaction().createCallableStatement("{call paq_w_ListadoSiniestralidadART. p_sinsiniest(?,?,?,?) }",0);
cs.registerOutParameter(4,OracleTypes.VARCHAR);
cs.setInt(1,paramContrato.intValue());
cs.setString(2,paramFechaDesde);
cs.setString(3,paramFechaHasta);
cs.setString(4,paramNombreArchivo);
cs.executeQuery();
String nomArchivo = cs.getString(4);
System.out.println("### " + nomArchivo +" ###");
catch(SQLException e)
The weird thing is that, I was expecting a big big exception but the only thing I got is
### Error ###
The String I am expecting is a file's name !; so I am a little bit confused...
Also I didn't know where to post so If it's in the wrong category... I apologize !... If anyone need more details, I'll be checking out... The account I am working on is an Insurance company, who is the one who provide access to the DB and the procedures... So I can't check what's inside...

Please provide your Java and OS versions, the JDBC jar file and the Oracle DB version being used when you post.
>
I was expecting a big big exception
>
Then why do you have an empty exception block? That just makes it disappear so you won't see one if it happens.
And your code has
cs.registerOutParameter(4,OracleTypes.VARCHAR);
cs.setString(4,paramNombreArchivo);You use 'registerOutParameter' for an OUT parameter and the 'setXXX' methods for other parameters.
Remove the 'setSTring' for the OUT parameter.
Then as malcollmmc already said
>
Sounds like the PL/SQL is returning "Error" as the 4th parameter of the call
>
The actual value returned by PL/SQL is strictly determined by the PL/SQL code and Java and JDBC are not involved.
Fix the code problems, retest, and folllowup with whoever wrote the code if it still returns ERROR.

Urgent! Call stored procedure from jdbc vs. call from sqlplus?

Hello I met a strange problem when using JDBC (to Oracle). I have a stored procedure mypack.myproc, which updates a table (only one row and one column in the table). I found that when I called the procedure directly from sql*plus, like:
==========
BEGIN
mypack.myproc;
END;
==========
the value is 2, which is correct.
However, if I call the procedure from with in java via jdbc, the value become 591 (which is ridiculous), the jdbc call looks like:
================
cstmt = con.prepareCall("{call mypack.myproc}");
cstmt.executeUpdate();
con.commit();
================
This is really wield, Any idea?
Thanks

Hey buddy, it's you again. Just let you know that you are right. The problem is caused by mis-match between jdbc date and oracle date (that procedure is used to do some date calculation). My co-worker suggested me to add this statement in the procedure, and it did solved problem:
================
DBMS_SESSION.SET_NLS( 'NLS_DATE_FORMAT', '''DD-MON-RRRR''' );
================

How to use @jws:sql call Stored Procedure from Workshop

Is there anyone know how to use @jws tag call Sybase stored procedure within

David,
In the current release, we do not support calling stored procedures from a
database control. You will have to write JDBC code in the JWS file to call
stored procedures.

David,
You can use a database control to obtain a connection from any JDBC
Connection Pool configured in the config.xml file. The JDBC Connectionpool
could be connecting to any database, the database control is
independent
of
that.

Can't call a procedure from a PLSQL Library inside forms 10g

Hello,
I build a plsql library using forms builder, then I compile it and add to FORMS_PATH.
I try to use a procedure from that lib so i attached the library to form (without path), then in then WHEN-BUTTON-PRESSED event I call one procedure from that library and i get this message :
error 201 at line 6 , column 2
identifier 'LIST_ADD_ALL' must be declared
---- MY CODE compiled ok with out errors i've got pll and plx
declare
     START_LIST_ID ITEM := FIND_ITEM('LIST16');
     END_LIST_ID ITEM := FIND_ITEM('ITEM18');
begin
     LIST_ADD_ALL(START_LIST_ID, END_LIST_ID);
end ;
I dont know if to put some kind of public declaration.
can anyone help me please.

In that case, use a batch file to start Form Builder to control your environment settings. The batch file ( e.g. FormsBuilder.bat ) should look roughly like this:
set oracle_home=C:\Oracle\Dev10g
set forms=%oracle_home%\forms
set nls_lang=AMERICAN_AMERICA.WE8MSWIN1252
set tns_admin=c:\oracle\admin
set ca_uprefs=c:\data\oracle\10g\uprefs
set path=%oracle_home%\bin;%path%
set forms_path=c:\data
set oratemp=c:\temp
start frmbld.exe

Calling a Procedure from a Button?

Hi All,
I'm using Oracle Application Express 11g & I'm currently working on an application. One of the requirements for this particular application is that a user has to be able to enter an applicant's id number (in the id textfield) & if a user clicks a button then they should be able to check in the db whether the applicant exists or not. If the applicant exists then name & surname textfields should be populated with values from the database corresponding to the id number & all these three textfields should be read only. If the applicant doesn't exist then the user will be directed to a page where he/she will fill in new applicant's details.
So, I wrote the following procedure to do that:
CREATE OR REPLACE PROCEDURE search_applicant(
P17_APPLICANT_IDNUMBER IN FIR_APPLICANT.applicant_idnumber%TYPE,
P17_NAME OUT FIR_APPLICANT.name%TYPE,
P17_SURNAME OUT FIR_APPLICANT.surname%TYPE,
P17_COUNT IN FIR_CURRENCY.currency_id%TYPE) IS
BEGIN
SELECT count(*)
INTO P17_COUNT
FROM fir_applicant
WHERE applicant_idnumber = :P17_APPLICANT_IDNUMBER;
IF P17_COUNT > 0 THEN
SELECT name,surname
INTO P17_NAME, P17_SURNAME
FROM fir_applicant
WHERE applicant_idnumber = :P17_APPLICANT_IDNUMBER;
dbms_output.put_line('Name: ' || P17_NAME || ' & Surname: ' || P17_SURNAME);
ELSE
dbms_output.put_line('Applicant does not exit.');
END IF;
EXCEPTION WHEN NO_DATA_FOUND THEN
dbms_output.put_line('Applicant does not exit.');
END;
So far I have not been able to find any help in this regard. I know how to invoke a javascript from a button but I'm not sure how to go about this one.
Any help in this regard is highly appreciated.

Calling stored procedures from entity object and application module

Hello
I've put in place an EntiyImpl base class containg helper methods to call stored procedures.
I now need to call stored procedures from the application module.
Apart from creating an application module base class and duplicating the helper method code is there a way
to share the helper methods for calling stored procedures between the entity impl and application module impl ?
Regards
Paul

Does the helper code depend on features of a particular entity object instance, beyond its database transaction?
If so, I'm not sure I see how it could be used from an application module class.
If not, here's what you do:
Step 1:
Parametrize the database transaction--you might even want to. So instead of
protected myHelperMethod(Object someParam) {
DBTransaction trans = getDBTransaction();
change this to
protected myHelperMethod(DBTransaction trans, Object someParam) {
Step 2: make the method public and static--once you parameterize the DBTransaction, you should be able to do this.
public static myHelperMethod(DBTransaction trans, Object someParam) {
Step 3: Remove the method from your EntityImpl base class into a utility class:
public abstract class PlSqlUtils {
private PlSqlUtils() {}
public static myHelperMethod(DBTransaction trans, Object someParam) {
When you want to call the method from an application module, entity object, or even view object class, call
PlSqlUtils.myHelperMethod(getDBTransaction(), paramValue);
Unlike Transaction.executeCommand(), this lets you provide functionality like setting procedure parameter values, retrieving OUT parameter values, etc.
Hope this helps,
Avrom

Calling Stored Procedures from Discoverer

Does anyone know if I can call stored procedures from Discoverer? I know it supports Registered PL/SQL functions. If yes, can I find any documentation. Any information will be very helpful.
Thanks in advance!
Ning

One way I can think of to do that would be to use function with pragma restrict references. You can then use the function as a column in a SQL query to make a folder in Discoverer.
