Calling stored procedure in a method validation

Hi guys.
Please I need help..
In an Entity object called customers there is a field called customer_id.
Before recording in the database is necessary that a procedure to be executed, returning a boolean value saying that this record is ok.
I would like to know how to implement a call to a stored procedure using the method of validation of the entity
and obtain the return value of the procedure to validate the transaction ...
Someone could help me.. I´m begginer in Jdeveloper and I´m using Jdev 10.1.3.4 ADF faces
thanks...

Calling stored procedure from session bean method

I have a situation like this :
I have one method on a stateless session bean (and I mark this method as container managed transaction). For database related stuff, I am not using entity beans, I am using my own layer of OR mapping. This method does a lot of stuff and it involves many trips to the database, as a result of which the performance is very poor. I have identified certain pieces of functionality from this method which I think can be moved to stored procedures, while some of the functionality can still remain in the session bean method. So my scenario is like this :
session bean method start
store some data in tables(using my OR layer)
call the stored procedure
session bean method end
My question is :
Will the data that I am storing in tables from within the session bean method, be available to the code executing inside stored proc.
secondly, how do I sync the transcation which is being initiated by the container with the transaction under which the stored proc is executing or is it that the stored procedure code will also be executing under the container managed transcation.
Thanks

Hi Vimal,
Will the data that I am storing in tables from within
the session bean method, be available to the code
executing inside stored proc.There's only one way to find out (isn't there?)
secondly, how do I sync the transcation which is
being initiated by the container with the transaction
under which the stored proc is executing or is it
that the stored procedure code will also be executing
under the container managed transcation.Again, why not just "suck it and see!"
[Or is there some reason why you can't?]
As I interpret the EJB specification, if the transaction attribute for your session bean method is such that it starts a transaction, then that transaction will be terminated when the method completes -- and every operation that occurs within the framework of that method will be in the one transaction.
In other words, your database stored procedure should execute within the same transaction as your O/R mapping layer.
However, how OC4J behaves may not exactly follow what is written in the (EJB) specification. Hence I repeat, "try it and see for yourself".
Put it this way: as far as I know, the only way that your stored procedure would NOT see the changes made by your O/R mapping layer is if they both executed in separate transactions and the O/R mapping layer did not commit its changes before the stored procedure began its execution.
Hope this has helped.
Good Luck,
Avi.

Calling Stored Procedure which returns single or multiple value

Hi All Experts,
I have written one stored procedure which is returning different
integer values according to condition.I am calling this
stored procedure through prepareCall() method then executeUpdate() method ,but it is always returning 1,not my desired value.
Pl also tell me,if my stored procedure returns more than one value
then how will i get those values in my java program?
Pl help by writing some sample code.
Thanx in Advance.
Pradipto

1) Create CallableStatement
2) For each of returning value you have to call RegisterOutParameter()
3) For others user setXXX() method depending on type of parameter
4) call
5) use vars registered through RegisterOutParameter() - all your values should be there

Calling Stored Procedure by clicking a button.

Hi,
I am developing an application using Oracle JHeadstart 10.1.3 Preview Version 10.1.3.0.78
I want to call Stored Procedure using a parameter from a jspx page.
In a jspx page I want to put a button. When the button will be clicked, it will send the ID as a parameter and call the Stored Procedure using that parameter.
Can anybody tell me how I can do this?
Your help would be very much appreciated.
Thanks

Hi Eduardo or Steven,
Could you please help me explaining how to put the method I created in an ADF Faces page as button.
I draged and droped the method in the ADF Faces page and it is giving me an error:

Call stored procedures in adf

hi all,
is there possible call stored procedures in adf.
thanks

Hello,
I found your post interesting and i'm going to leave you a link where sql statements are referenced in ADF, by creating methods in the AppModule.
Amit Sharma's Blog: How to execute sql using ADF Application
I add that the structure is the same if you want to do select statements or insert, the only change (beside the statement itself and the params) its the executeQuery code, you have a execute also and it depends on what type of sql statement you're executing, you can read about that.
executeQuery() -> select queries
execute() -> create queries, and probably insert and update.
Hope it helps and regards,
Frederico.

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

Need sample source code for calling stored procedure in Oracle

Hi.
I try to call stored procedure in oracle using JCA JDBC.
Anybody have sample source code for that ?
Regards, Arnold.

Thank you very much for a very quick reply. It worked, but I have an extended problem for which I would like to have a solution. Thank you very much in advance for your help. The problem is described below.
I have the Procedure defined as below in the SFCS1 package body
Procedure Company_Selection(O_Cursor IN OUT T_Cursor)
BEGIN
Open O_Cursor FOR
SELECT CompanyId, CompanyName
FROM Company
WHERE CompanyProvince IN ('AL','AK');
END Company_Selection;
In the Oracle Forms, I have a datablock based on the above stored procedure. When I execute the form and from the menu if I click on Execute Query the data block gets filled up with data (The datablock is configured to display 10 items as a tabular form).
At this point in time, I want to automate the process of displaying the data, hence I created a button and from there I want to call this stored procedure. So, in the button trigger I have the following statements
DECLARE
A SFCS1.T_Cursor;
BEGIN
SFCS1.Company_Selection(A);
go_Block ('Block36');
The cursor goes to the corresponding block, but does not display any data. Can you tell me how to get the data displayed. In the future versions, I'm planning to put variables in the WHERE clause.

Call stored procedure with OUT parameter

Hello,
I have created a short-lived process. Within this process I am using the "FOUNDATION > JDBC > Call Stored Procedure" operation to call an Oracle procedure. This procedure has 3 parameters, 2 IN and 1 OUT parameter.
The procedure is being executed correctly. Both IN parameters receive the correct values but I am unable to get the OUT parameter's value in my process.
Rewriting the procedure as a function gives me an ORA-01460 since one of the parameters contains XML (>32K) so this is not option...
Has someone been able to call a stored procedure with an OUT parameter?
Regards,
Nico

Object is Foundation, Execute Script
This is for a query, you can change to a stored procedure call. Pull the value back in the Java code then put into the process variable.

Creation of DB Adaptert for calling stored procedure in MS SQL server

Hi,
I need to create a DB adapter to call a stored procedure in MS SQL Server.
I have gone thru the thread MS SQL Server database connection
It mentions that we need to use a command line utility for generating the wsdl and xsd for calling stored procedures in MS SQL server. Please provide information where to find this utility and how to use it.
Any links to tutorials are welcome.
Thanks !!.
Silas.

Command line is required for stored procedures, if you are using the basic options you don't need to worry.
(1) Download MS SQL Server 2005 JDBC Driver from Microsoft Site. http://msdn.microsoft.com/en-us/data/aa937724.aspx
(2) The download is self extracting exe file. Extract this into Program Files on your machine. It should create folder as "Microsoft SQL Server 2005 JDBC Driver"
(3) In above mentioned folder search for sqljdbc.jar copy this file into JDeveloper\JDBC\lib folder.
(4) Open JDeveloper/jdev/bin/jdev.conf file add following entry.
AddJavaLibPath C:/Program files/Microsoft SQL Server 2000 Driver for JDBC/lib
While executing this step make sure that your JDeveloper is closed.
(5) On command prompt go to J Developer folder and execute following command
jdev -verbose
This will open JDeveloper.
(6) Now go to JDeveloper > Connections > Database Connections > New Database Connection
(7) Select Third Party JDBC
(8) Specify MS Sql Server User Name, password and Role.
(9) In connection page specify following
- Driver Class: com.microsoft.sqlserver.jdbc.SQLServerDriver
- For class path browse to C:/Program files/Microsoft SQL Server 2000 Driver for JDBC/lib folder, select sqljdbc.jar add it as library.
- Specify URL as following.
jdbc:sqlserver://SERVERNAME:1433;databaseName=MSSQLDBNAME;
(10) Go to Test page and test it.
cheers

Calling Stored Procedure from Oracle DataBase using Sender JDBC (JDBC-JMS)

Hi All,
We have requirement to move the data from Database to Queue (Interface Flow: JDBC -> JMS).
Database is Oracle.
*Based on Event, data will be triggered into two tables: XX & YY. This event occurs twice daily.
Take one field: 'aa' in XX and compare it with the field: 'pp' in YY.
If both are equal, then
if the field: 'qq' in YY table equals to "Add" then take the data from the view table: 'Add_View'.
else if the field: 'qq' in YY table equals to "Modify" then take the data from the view table: 'Modify_View'.
Finally, We need to archive the selected data from the respective view table.*
From each table, data will come differently, means with different field names.
I thought of call Stored Procedure from Sender JDBC Adapter for the above requirement.
But I heard that, we cannot call stored procedure in Oracle through Sender JDBC as it returns Cursor instead of ResultSet.
Is there any way other than Stored Procedure?
How to handle Data Types as data is coming from two different tables?
Can we create one data type for two tables?
Is BPM required for this to collect data from two different tables?
Can somebody guide me on how to handle this?
Waiting eagerly for help which will be rewarded.
Thanks and Regards,

Hi Gopal,
Thank you for your reply.
>Is there any way other than Stored Procedure?
Can you try configuring sender adapter to poll the data in intervals. You can configure Automatic TIme planning (ATP) in the sender jdbc channel.
I need to select the data from different tables based on some conditions. Let me simplify that.
Suppose Table1 contains 'n' no of rows. For each row, I need to test two conditions where only one condition will be satisfied. If 1st condition is satisfied, then data needs to be taken from Table2 else data needs to be taken from Table3.
How can we meet this by configuring sender adapter with ATP?

>How to handle Data Types as data is coming from two different tables?
If you use join query in the select statement field of the channel then whatever you need select fields will be returned. This might be fields of two tables. your datatype fields are combination of two diff table.
we need to take data only from one table at a time. It is not join of two tables.

Calling Stored Procedure with in Stored Procedure

I have one stored procedure A, I want to call Stored procedure A from Stored Procedure B and want to give input parameter to Stored Procedure A within Stored Procedure B using while loop.
i.e I have one stored procedure A which uses Telephone number as input parameter and pull out data
I want to create one more stored procedure B which will call stored procedure A internally and give telephone number one by one using while loop and push the result in Table C.

Doesn't sound a good idea in terms of performance or design. OK, what's your query?
The concept is:
create or replace procedure Proc_A (p_phone varchar2)
is
Begin
Insert into Tablec (col1, col2, col3, phone) values (val1, val2, val3, p_phone);
Exception
When no_data_found then
do what...
End;
Create or Replace Procedure Proc_B as
Begin
For i in (select phone_no from customer)
Loop
Proc_A(i.phone_no);
End Loop;
End;
/Once again, I have to say, it's a bad idea. You may well do it within a single procedure or even a single SQL. Tell us your exact requirements and we'll be able to help you

Calling Stored Procedure without JDBC-Adapter

Hallo,
as it is not possible calling Stored Procedures with the parameter Typ Record in Oracle my question: It is possible connecting to DB using native java-code for example in Mapping?
Thanks in advance,
Frank

Hi Frank,
Maybe you can use the DB look up using the JDBC adapter in your mapping.
Just check this blog for the same,
/people/siva.maranani/blog/2005/08/23/lookup146s-in-xi-made-simpler
As for calling an Oracle Strored Procedure, it is possible using a RECEIVER JDBC adapter, but not a SENDER JDBC adapter.
<i> import the jdbc-driver (oracle) in an archive in Designer.</i>
Also, this imported archive should be under any Namespace, but, it should be in the same SWCV as the one in which the mapping is being executed.

Bhavesh

CALLING STORED PROCEDURE IN DATABASE FROM FORMS4.5

Is there any body know how to call stored procedure from Forms 4.5 ?
I am writing a when-button-pressed trigger.
Put the stored procedure name on there. But
it said "stored procedure name is not declared on this scope".
Thanks a lot
null

Try logging in to SQL*Plus and running the procedure, e.g....
SQL> begin
database_procedure_name(update_web);
end;
If it runs OK there, then it should run from within your form (provided that you are logged in as the same user as the test with SQL*Plus.

Calling stored procedure in OCCI

Hi, Guys.
I triy to call stored procedure in Oracle database server.But i have problems with taking of the OUT parameters.
How to call the procedure corectly?
Depend on Oracle manual everything is fine but as we see that is not.
Here is the 2 lines that make the problem.
statement->registerOutParam(2, Type::OCCIINT, sizeof ( if_false ) );
statement->registerOutParam(3, Type::OCCIString, sizeof ( __result ) );
I can't access Type::OCCIINT and Type::OCCIString.
I tried and Type::OCCISTRING but without any result.
Can you help me?
This is the all code i use:
Environment *env = Environment::createEnvironment ( Environment::DEFAULT );
Connection *conn = env->createConnection ( user, pass, osid );
Statement * statement = conn->createStatement ( query );
ResultSet * result = statement->executeQuery ( query );
result->setCharacterStreamMode ( 2, 10000 );
statement->setSQL ( "BEGIN tracetst.get_tst_moduls ( :1, :2, :3 ); END:" );
int if_false;
string __result;
statement->setString ( 1, "116714020010" );
statement->registerOutParam(2, Type::OCCIINT, sizeof ( if_false ) );
statement->registerOutParam(3, Type::OCCIString, sizeof ( __result ) );
statement->executeUpdate();
if_false = statement->getInt (2);
/* Set the 1,2 args into err_result and modules. The action is only with these */
err_result = if_false;
__result = statement->getString (3);
cout << if_false;
cout << __result;
//printf ( result );
//statement->executeUpdate ( query );
env->terminateConnection ( conn );
Environment :: terminateEnvironment ( env );
While compiling I have an error message.Here it is :
trace.cpp: In member function `const char* oracle_io::get_data()':
trace.cpp:668: error: `oracle::occi::Type' is not an aggregate type
Tha is the line adn the next line is same :
statement->registerOutParam(2, Type::OCCIINT, sizeof ( if_false ) );
statement->registerOutParam(3, Type::OCCIString, sizeof ( __result ) );

Thanks in advance.
P.S. I would like to thanks to Amogh for helping me before.

Did you remove the colon after END ?
        Environment *env = Environment::createEnvironment(Environment::OBJECT);
        Connection *conn = env->createConnection("scott","tiger","inst1");
        Statement *stmt;
        int num; string name;
        try
                stmt=conn->createStatement();
                stmt->setSQL ( "BEGIN scott.test ( :1, :2, :3 ); END;" );
                stmt->setString ( 1, "11" );
                stmt->registerOutParam(2, OCCIINT,sizeof(num));
                stmt->registerOutParam(3, OCCISTRING,sizeof(name));
                stmt->execute();
                num=stmt->getInt(2); name=stmt->getString(3);
                cout<<num<<"   "<<name<<endl;
        catch (SQLException &ex)
                env->terminateConnection(conn);
                Environment::terminateEnvironment(env);
                cout<<ex.getMessage();
        env->terminateConnection(conn);
        Environment::terminateEnvironment(env);
...Rgds.
