Procedure and Functions from ADF View Layer

Hi,
Before i ask my question ,I would like to mention that I have done lot of googling on this topic before asking this question.
http://adfhowto.blogspot.in/2010/11/call-db-procedure-or-function-from-adf.html
http://adf-tools.blogspot.ca/2010/03/adf-plsql-procedure-or-function-call.html
Lot of threads on otn forum too on this topic.
I m pretty new to ADf too.
Now most of our logic is in procedures and functions ,so on various events on form(view layer) I need to call procedure and function and then return values back to value layer too.
Now the approach mentioned in the link above is good whats best approach to return out parameters to view layer considering i will be using either the DbCall class for all calls to procedures and functions
I am thinking of this approach to Create a view with static fields,and in Model layer set values for these fields and access them in view layer or binding view controls to these fields.
From View layer i will call the methods in AppmodImpl which will be calling procedure( methods will be exposed as Client Interface)
Also in few articles i came across generic CallStoredProcedure and CallStoredFunctions.
But my main concern is how to share out parameters with view layer....can anyone give link of showing application of it on view layer.
Regards,

From your subject. am stating that, dont do all those stuff in backing bean. backing bean is 1:1 mapping with your .jpsx or .jsff .
best approach would be call those things your Application Module(model layer) exposed it. access the method over your pagedef. well said by ram.

Use of Procedure and Functions in ADF BC

Hi,
In ADF 11g
1. can I use oracle function and procedures ( having in and OUT parameters) to expose as service interface
2. if yes , How can this be done. and what are the allowed data types as input to procedure/function and can be returned by procedure/function
3. How the transaction control will be achieved using ADF BC service interface.
E.g. one ADF BC creates orders in order details and second creates Order lines in Order lines table. Now if order is created successfully but line creation fails then I want order to be rolled back also.
Thanks.

google it out.

Without calling stored procedure or functions from database

Hi,
I am using Jdeveloper 11.1.1.5.0.
=>How to do PL/SQL procedures and functions in ADF without calling stored procedure or function from DB?

S, PL/SQL procedures and functions are done in Application Module class or in managed bean..By calling the stored procedures or functions from DB.
But I am asking how to do if DB doesn't have any procedures,triggers and functions.

How can I use the procedures and functions in my library

hello, all
I have a pl/sql library MYLIB.pld, MYLIB.pll and MYLIB.plx.
How can I invoke procedures and functions there in JDeveloper?
Thanks.
Damon

I am indeed using ADF BC to re-develop the oracle application.
Here is my situation:
We have an oracle form application.
Our objective is to try to re-use the existing sources in the form application as much as possible:
1. tons of procedures and functions in a pl/sql library(a file with extension name portfolioLib.pll or portfolioLib.plx);
2. tons of form-level triggers, data-block triggers and item-triggers;
3. tons of database stored procedures and triggers;
After doing a research on JDeveloper, we decide to use ADF Swing+ADF BC to re-develop the application.
My opinion for the above three kinds of sources in our form application is:
for 1: we try to move most of procedures and functions into database(except Form build-in);
for 2: we try to wrap those triggers in a SQLJ class;
for 3: we try to call database procedures and functions with PreparedStatment or CallableStatement;
I just do a test on a post-query trigger on a data-block:
I created a sqlj file, named testSQLJ.sqlj in the test.view package;
I tried to call it in createInstanceFromResultSet of testDeptVOImpl.java which is test.model package,
I was told that testSQLJ cannot be found there. why?
How can I call some classes from test.view package in some classes of test.model?
I read some documents about how to deal with post-query trigger in JDeveloper: create a view with SQL statement, but it seems that it does not support pl/sql statement there.
Can you give me some opinion about the above stuff?
I really appreciate your help.

Procedure and function diff

procedure compile once and run at manytime untill it s coding changes
but
function every time will be complied
is it true this statement?????????
any one help me?????????

No. It is a smelly statement.
Where did you hear it? Can you share the URL? Perhaps there are more to this.. (would hope so, else it would mean someone has very twisted and warped views of how code compilation works).
There are no differences from a PL/SQL compiler and run-time perspective between a function and a procedure - except when it comes to popping the call stack (as a function will always return a value up the call stack, a procedure not). So procedures and functions are treated the same way by the compiler and the run-time engine. There are no differences between the two so large, that requires the one to be recompiled all the time and the other not.

Diif between Stored procedure and function

HI
I want all the differences between Stored procedure and function.
Even the basic diff is Procedure does not return any value and Function must be...
Thansk In advance...

1) Functions are used for computations where as procedures can be used for performing business logic That's an opinion on usage not an actual difference.
3) You can have DML(insert,update, delete) statements in a function. But, you can not call such a function in a SQL query.Not true. As User defind functons limitations we can use a function that issues DML in a SELECT statement, if it uses the PRAGMA AUTONOMOUS_TRANSACTION.
4) Function parameters are always IN, no OUT is possibleEasily refutable...
SQL> CREATE OR REPLACE FUNCTION my_f (p OUT NUMBER) RETURN DATE
2 AS
3 BEGIN
4     p := to_number(to_char(sysdate, 'DD'));
5     RETURN sysdate;

(1) A function must return a value

There are some minor difference in allowable syntax but they are to do withj RETURN values.

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.

Procedure and function

hi folks,
procedure and function are doing a same job then why we using function,please give explanation in real time scenario ...

When talking about PL/SQL only, everything that can be achieved with a function can also be achieved with a procedure using out parameters, thus you don't really need functions.
However, a function may be used as a "syntactical convenience" in that you can write expressions like this in your PL/SQL code:
total_salary := get_total_salary(dept_id => my_dept);
(assuming you have defined the function get_total_salary).
You may find this more readable than writing
get_total_salary(result => total_salary, dept_id => my_dept);
(assuming you have defined the procedure get_total_salary with an out parameter result).
This is the same as with e.g. the CASE statement. You don't really need it, every CASE statement might be expressed with IF .. THEN statements as well. However using CASE may be more convenient and make your code more readable. Another example are loops, where you have different flavours, while everything might be expressed using one sort of loops (e.g. WHILE).
In addition, you may use functions in SQL, while this is not possible with procedures, i.e. after defining some function f, you may write SQL like this:
select * from t where f(id) = 0;

How to test procedures and functions of pl/sql

I am working as a QA basically i got a new assignment of testing functions and procedures, and packeged bodies. Can any one help me in this matter.
Please help me.
Hi i am new to oracle I want to test procedures and functions,
and packaged bodies of pl/sql.

It depends on what you meant by "testing". I guess you need to check that routines (functions, procedures, packages etc) in valid state and execute without errors. The simpliest way is to get some development tool like TOAD (http://www.quest.com), Oracle Maestro (http://www.sqlmaestro.com) or PL/SQL Developer (http://www.allroundautomations.com). You can connect with them to database and look at the routine state VALID or INVALID. You can recompile them, run and even debug. I guess this should be enough.
Alternatively you can do same thing from sqlplus. Of course with lesser comfort. You need to write certain SQL statements. For example i want to find invalid procedures:
SQL> select OBJECT_NAME, OBJECT_TYPE from USER_OBJECTS where STATUS='INVALID';
To check how procedures work you need to execute anonymous PL/SQL block like this:
declare
     /* local variables declaration */
     NAME VARCHAR2(4000);
     PRESIDENT_ID NUMBER(38);
     ID NUMBER(38);
begin
     /* setting up variables */
     NAME:='MICROSOFT';
     PRESIDENT_ID:='BILLY';
     ID:=NULL;
     /* calling routine */
     GEOMETRY.ADD_COMPANY(NAME,PRESIDENT_ID,ID);
end;

Regarding Procedures and functions

can we pass a cursor,table or ref cursor to a procedure and functions and can a function return cursor,table or ref cursor to a procedure and functions?please if possible give some examples with explanations
thanks in advance..

Hi,
The definition for a Procedure or Function can be edited by selecting Edit from the drop-down menu for the Procedure/Function object in the Browser.
The definition can then be edited as text, and so Table, REF CURSOR, ... parameters or return types can be added.
(After completing the edit, select Save from the File menu, or alternatively Close the tab displaying the definition and select Yes to the Save Changes dialog.)
The Oracle Database PL/SQL Language Reference documentation contains some examples of Procedure and Function definitions.

Passing arrays through multiple PL/SQL procedures and functions

I am maintaining a large PL/SQL application. There is a main procedure that is initially called which subsequently passes information to other PL/SQL functions and procedures. In the end an error code and string is passed to PUT_LINE so it can be displayed. What I would like to be able to do is have an array that stores an error code and string for each error that it comes upon during going through each of the procedures and functions. This would involve passing these codes and strings from function to function within the pl/sql application. What would be the best way to implement this and is it possible to pass arrrays or records to other PL/SQL functions? Thanks.

Hi LenFinkel,
May I know what is purpose of this requirement, as olaf said,you may parse the T-SQL code (or the execution plan), which is not that easy.
I have noticed that the condition values in your Stored Procedure(SP) are hard coded and among them there is a date values, I believe some day you may have to alter the SP when the date expires. So why not declare 3 parameters of the SP instead hard coding?
For multiple values paramter you can use a
table-valued parameter. Then there's no problem getting the values.
If you could elaborate your purpose, we may help to find better workaround.

How to find out list of procedures and functions inside a package

How I can find out the list of Procedures and Functions inside a Package.

Look at ALL_PROCEDURES and ALL_ARGUMENTS.

Are the Pl/sql procedure and function atomic by themself

i want to ask a question does oracle pl/sql procedure and function support Atomicity for the database by themself , or they became atomic incase we call them using begin -- end;

You appear to be discussing transaction scope which is completely independent of PL/SQL blocks like procedures or how you call procedures. It's all in where commits (or rollbacks) are issued.
If you have a procedure like this
CREATE PROCEDURE p1
AS
BEGIN
INSERT INTO some_table( key, value ) VALUES( 1, 'Foo' );
INSERT INTO some_table( key, value ) VALUES( 1, 'Bar' );
END;where the first statement succeeds and the second statement fails as a result of a duplicate key, there will still be a Foo row in the table but the procedure will have thrown an exception. The caller of the procedure may choose to commit or rollback the change-- that will determine whether the first statement's results are made permanent. If you have a procedure like this,
CREATE PROCEDURE p1
AS
BEGIN
INSERT INTO some_table( key, value ) VALUES( 1, 'Foo' );
commit;
INSERT INTO some_table( key, value ) VALUES( 1, 'Bar' );
END;the commit will make the first insert permanent regardless of whether the second statement fails no matter what the calling code does (that's one reason that putting commits in stored procedures is generally a bad idea-- the caller is in a much better position to know what other uncommitted work has been done and whether it is safe to commit.

Can't drag and drop from page view to desktop even though plus icon shows up for duplicating the page. On Mac 10.9.2 Acrobat XI. I don't want to extract through the menu and associated dialogues. Its slow and cumbersome.

Hi Peterbruce,
Acrobat for Windows will let you select pages in the Pages panel and drag them to your desktop, but that isn't an option in Acrobat for Mac OS. You can drag thumbnails from the Pages panel in one doc, to the Pages panel in another, however.
