Book of Oracle 8i Program Units

Hi,
I have book of Oracle 8 Program Units but i want to know that is there any book of Oracle 8i Program Units.
The certifcation course for the Internet Developer Track shows some new chapters which are not in Oracle 8 Program Units book .
I have Oracle 9i PL/SQL book so they exits in Oracle 9i PL/SQL Programming book.
Please help me out from this confusion.
Thanks & Regards,
Abdul

Hi,

Forms Program units don't work in Oracle Apps Server 10.1.2.2

Dear all,
I created a simple form with some triggers and a button. Everything works fine when I run the form using my PC's local OC4J. If I deploy the form in Oracle Application server 10.1.2.2 and run from there, none of the triggers or program units is working. What could be the reason?
For example, in when-button-pressed trigger, I have the following code.
go_block('block1');
execute_query(no_validate);
When I press the button, nothing happens.
Can you please help?
Regards,
Sanjeev

that's indeed your problem , you need to recompile on solaris
frmcmp.sh you can find this in you ias home/bin directory
eg
frmcmp.sh module=your form.fmb user=
for this you need to have an active Xwindow
you can use frmcmp_batch.sh too then normally you don't have to set the Xwindow
I putted already some scripts to do this on the forum
search for frmcmp.sh

Can I create a dynamic cursor in a program unit on oracle form....

Hello folks,
can I create a dynamic cursor on client side ( in a program unit on the oracle form), is it possible, I Know how to create it on server side using Ref cursor, but on client side i got this message (can't be created on client side or something like that).... please if someone can help

> select count(*) from t_comsis
<p>But when you put that select string into a varchar2 variable, it won't compile. Which makes it hard to create anything "dynamic".
<p>In Forms, you can create and populate a record group dynamically, which is ok as long as your select will not retrieve too many (more than several hundred) rows.
<p>Or, your other option is to use the Forms Exec_SQL dynamic sql package.

Error : ORA-06508: PL/SQL: could not find program unit being called

Hi
I got surprise issue while testing my Oracle code . Let me explain first the environment detail . Our appliaction built on
Java/J2EE(Weblogic) and backend is Oracle 11g re2 . While calling from java it call thru different user which have been provide
synonym and exectue option for corresponding procdure ,
I created on package EXTRACT_CUSTOMER_INFO_PK which will exract data to text file using UTL_FILE ( direcory , UTL_FILE grant is provided to DB user).
Now this package has been called from rp_execute_procedure_pr -- Here I is the code
CREATE OR REPLACE PROCEDURE RP_EXECUTE_PROCEDURE_PR
i_atlas_job_schedule_fk IN atlas_job_schedule.atlas_job_schedule_pk%TYPE,
i_job_id IN atlas_job.job_id%TYPE,
i_parm_value IN atlas_job_schedule.parm_value%TYPE,
o_status_code OUT NUMBER,
o_status_mesg OUT VARCHAR2
IS
-------Other old code which is not relevent for this issue ----
--------Other old code which is not relevent for this issue ----
----Below code I added ----
ELSIF l_job_id = 'CUST_EXTRACT' THEN
EXTRACT_CUSTOMER_INFO_PK.customer_report ( i_parm_value ,
o_status_code,
o_status_mesg ) ;
-- o_status_code := -99999999;
--o_status_mesg := 'PARTHA PARTHA PARTHAcess terminated!';
ELSE
o_status_code := -20300;
o_status_mesg := 'Job Id : ' || l_job_id || ' NOT found. Process terminated!';
END IF;
update_log_auto
ajs_rec.atlas_job_schedule_pk ,
'Processing End Time (GMT): '
EXCEPTION
WHEN eProcError THEN
o_status_code := SQLCODE;
o_status_mesg := SUBSTR(vMsg ||'-'||SQLERRM, 1, 200);
WHEN OTHERS THEN
o_status_code := -20300;
o_status_mesg := SUBSTR(SQLERRM, 1, 200);
update_log_auto
ajs_rec.atlas_job_schedule_pk ,
'Error : '||SQLERRM||' '
update_log_auto
ajs_rec.atlas_job_schedule_pk,
'Processing End Time (GMT): '
END RP_EXECUTE_PROCEDURE_PR;
Now It compiled sucesfully . And while I did SIT then RP_EXECUTE_PROCEDURE_PR run fine and extracted txt file . But while I called it from Java procedure It gives us error like
Error : ORA-06508: PL/SQL: could not find program unit being called 02-AUG-2012 13:16:51.
As I told RP_EXECUTE_PROCEDURE_PR old proc and used by other proc , So I first suspect issue is newly added code or may be some grant or synonym ( Although it should not be )
so I created public synony amd gave execute grant to my pkg to public .
But it repeat same error .
I did lot of R&D on my pkg but nothing happen . Finally I remane my new pkg RP_EXTRACT_CUSTOMER_INFO_PK and it works fine
I need to know what is the RCA for it . I donot think any dependecy issue as renaming pkg is working fine .
NB my DB user is iATLAS and Javauser is SUDEEP
Thanks in Advance
Debashis Mallick

First of all If i run the main procedure in like below in my Schema it is working fine
begin
-- Call the procedure
rp_execute_procedure_pr(i_atlas_job_schedule_fk => :i_atlas_job_schedule_fk,
i_job_id => :i_job_id,
i_parm_value => :i_parm_value,
o_status_code => :o_status_code,
o_status_mesg => :o_status_mesg);
end;
So thre is no question of parameter .... or Invalid state etc . If it is parameter or Invalid state issue it will give other error.
Here problem is not syntax issue .
let me give u more detail regards this issue
1.. All objects corresponding to procedure all Valid
2.. If I test on the proc on my schema like above code . It works fine
3.rp_execute_procedure_pr is a old procudere which called for differner report generartion based on parameter passing . Also as extract_customer_info_pk called with in rp_execute_procedure_pr So there is no question of synonym or privilage issue for new procedure.
4. Suprising thing is if I rename and recreate package like extract_customer_info_pk _1 or rp_extract_customer_info_pk . Which are exactly same as extract_customer_info_pk and replace those new one with extract_customer_info_pk then it work fine in my java application
I think I make it clear the issue

Error while compiling program unit

Hi All,
I am working on oracle forms 10g.
I am getting an error "wrong no or types of arguments in call to 'COUNTCDRSTODELETE' ", while trying to compile my program unit.
The extract of my program unit is as written below:

pck_backout is a stored database package. The definition of two functions used above is as given below:
FUNCTION countcdrstodelete (
p_bmpf_id_array IN pkarray,
p_batch_size IN NUMBER
RETURN NUMBER;
FUNCTION areallcdrsopen (p_bmpf_id_array IN pkarray, p_batch_size IN NUMBER)
RETURN NUMBER;
where pkarray is defined as :
TYPE pkarray IS VARRAY (100) OF INTEGER;
Can anyone please tell me why i am getting wronf type or no of arguments error while calling the databse functions.
I guess, it has to do with the varray field. Can you please tell me if i am using any wrong syntax??
I request all the forms gurus to please help me with this.

Hi Fabrio,
I solved my problem.
I'd to actually define pkarray as sql type rather than PL/SQL type.
It's because oracle forms wasn't able to bind the varray defined locally in program unit with the varray defined in stored PL/SQL function.
Once i created pkarray as sql type and removed the declaration of varray in program unit and PL/SQL code, it worked.
Thanks for your reply though.

How to reference a user parameter in program unit

I tried to define a user parameter in Oracle Report 6i and I could reference it (&p_where_clause) in the main query but I failed to reference it in one of the program units. Here is the logic:
function CF_OTHER_COURSESFormula return Char is
cnt           number;
priority     number;
class_code     varchar2(8);
oc           varchar2(100) := null;
cursor oc_cur is
select class_code, branch_priority
from nominations n, employments e
where n.hkic_no = e.hkic_no
and e.staff_status_code = 'EMP'
and &p_where_clause --> contain "n.course_code in ('A','B','C')"
and n.hkic_no = :hkic_no
and n.class_code != :class_code;
begin
cnt := 1;
open oc_cur;
loop
fetch oc_cur into class_code, priority;
if oc_cur%notfound then
     exit;
end if;
if cnt = 1 then
oc := oc||class_code||'('||priority||')';
else
oc := oc||', '||class_code||'('||priority||')';
end if;
cnt := cnt + 1;
end loop;
close oc_cur;
return oc;
exception
when no_data_found then
return '';
end;
Does anyone tell me how to reference it in program unit? Does Oracle Reports 6i support this operation?

There hasn't been any changes to the way lexicals and bind variables work in Reports between 2.5 and 6i. There are different versions of PL/SQL and you might be hitting some problem here.
In your case, you shouldn't be using the query lexical "&p_where_clause" just the PL/SQL bind variable syntax ":p_where_clause". Since you're creating a PL/SQL cursor, you should probably use dynamic sql creation with a concatenation of the where clause to build up the SQL for the cursor. Check out the PL/SQL documentation for this.

Pd0-ppu017 program unit source must define a subprogram body or package

Hi
Iam new to oracle l and trying to teach myself
my problem is when I compile any function in program units of forms ,
the following error message obtained:-
pd0-ppu017 program unit source must define a subprogram body or package.
for example this ready function that I have just copied ,pasted
CREATE OR REPLACE FUNCTION TestTrig_body() RETURNS TRIGGER AS $$

what is the reason please?

VANPERSIE,
It looks like you are mixing sytax. Some of the Syntax used in a Database trigger (such as Before Insert, After Insert, etc) is specific to database triggers. Referring to :NEW and :OLD are specific to database triggers and can't be used as you are using them, unless you have data blocks names NEW and OLD. Also, when you refer to a item in a block, you must prefix the block or item name with the colon ":". Also, as aweiden points out, you define your return data type as "TRIGGER". The return type of a Function must be a valid Oracle data type. Therefore, your function should return a BOOLEAN, NUMBER, VARCHAR, or even a Ref Cursor, just to name a few. From the looks of your code, your function would simply return a value to indicate that the INSERT was successful. Therefore, you could rewrite your function something like:
CREATE OR REPLACE FUNCTION TESTTRIG_BODY() RETURNS BOOLEAN AS
BEGIN
   /* This example assumes you have data blocks in your form called: NEW_BLOCK and OLD_BLOCK. */
   INSERT INTO REPORT_TABLE
      (NUM_COL, OLD_VAL, NEW_VAL)
   VALUES
      (:NEW_BLOCK.NUM_COL, :OLD_BLOCK.CHAR_COL, :NEW_BLOCK.CHAR_COL);
   RETURN TRUE;
EXCEPTION
   WHEN OTHERS THEN
      RETURN FALSE;
END;Also, is there a particular reason you are manually INSERTing a record versus letting Oracle Forms handle this for you?
Hope this helps.
Craig...

Help plss Should a cursor be created in database or program unit in forms l

Where can i create a cursor should it be in database i.e isql plus using internet explorer or should i create the cursor in forms
forms can i create the cursor so that i can use the cursor in the post item trigger of the userid item of login page
Can i create the cursor in a package specification and how can i call that cursor into a post_text item trigger
details below
Iam working on a Online exam for students Dummy project using forms
The student 1st comes to a WELCOME page i.e form which asks him if he is a new student or registered stud
If he clicks registered pushbutton it takes him to a LOGIN page where there are two items userid and password.I am using a Validate_item OR Post_item trigger to fire after the student enters his userid.
I need to compare the entered userid with the userid stored in the database STUDENTS table which i created which consists of the registered students details.
Our project Guide suggested that we create a cursor and fetch each userid everytime into the cursor and compare the entered userid with the cursor.

hi Sqlstar,
Regarding to your all questions , i prefered that you search for a simple document or book in order to understand much more more about creating cursors.
however since this forum made to help people and to make a integerated community i would be glad to offer my help and going with you step bt step with your answers.
as for beginning
1) when you create the user_exists function in database , if you want to call it in the form level you would wirte a code like this
----WHEN-VALIDATE-ITEM------------user_id item---------
IF scheme_name.procedure_name(:block1.userid)!='TURE' then
   message('User Name is not correct');
   raise form_trigger_failure;
end if;
2) it's not a waste of recourse to make 2 validation of both userid and password
and as same you create a procedure for useris you should create a procedure for password where the user id is the outcomming of userid item in the form.
3)you have all choices to create the 2 procedures on database side or in the program unit at design time for the form it's up to you and as a small hint for you ,
when you create them in the program unit and want to call the procedures in the WHEN-VALIDATE-ITEM trigger you should denote the procedure name with the name of package first as following
-------[Package Spec Code]-------
PACKAGE user_validation IS
function user_exists (p_user_id number) return boolean;
end ;
--------------[Package Body Code]------
PACKAGE BODY user_validation IS
function user_exists (p_user_id number) return boolean
is
user_number number;
cursor c_user_id is
select user_id from <user_table>
where user_id=p_user_id;
begin
open c_user_id ;
loop
fetch user_id into user_number ;
return (true);
exit when c_user_id%NOTFOUND;
end loop;
execption when others then
return(false);
end user_exists;
end;
-----Calling at Validation level-----------
IF (user_validation.user_exists(:block1.userid))!=TURE then
   message('User Name is not correct');
   raise form_trigger_failure;
end if;
i hope this could be helpful engouh to start your application
Good Luck .
Regards
Omar

Lexical Parameter in Reports 6i Program Unit

A report I'm writing requires me to use the lexical parameter in a program unit rather than a query in the data model. Lexical parameters in a query have always worked with the example "WHERE &my_parameter". But using "WHERE :my_parameter" or "WHERE &my_parameter" in a program unit gave me the error "expression is of wrong type" so the code wouldn't compile in the editor.
The parameter returns "segment1 = '8675309' AND segment2 = 'Jenny'I was able to resolve it by using the first column of the expression and the replace function on the parameter so the program unit editor thinks it's a valid expression and the resulting line is a valid predicate that gets the correct data. Here's my example:
WHERE segment1 = replace(:my_parameter, 'segment1 = ')The replace function strips off the "segment1 = " from the lexical parameter so the resulting line that gets passed to the server is:
WHERE segment1 = '8675309' AND segment2 = 'Jenny'This solution will not work where the parameter could return something other than "segment1 = " at the beginning of the parameter string like "segment1 BETWEEN " or a different column name to compare other than segment1. Anyway, this is working but if there are better ways to do it I'd like to try them. Using Reports 6i with EBS 11.5.10.2.

You'll find explanations and examples here :

Error in executing mappings "could not find program unit being called"

I am trying to deploy a mapping from the control center in Oracle WareHouse Builder usign Oracle 11g . Here is what i exactly do , first I generate the mapping it goes okay with an insignificant warning .. After that I right click the mapping and click start (for exection to begin).. Eventually I get the error
STAGES_MAP

what does "could not find program unit being called" mean ?? I validated all my tables and its realated table and successfully deployed them ... but now the mappings is giving me trouble ??? Whas going on... I am confused.... Thansk....

It sounds as though you've generated but haven't actually deployed the mapping to the DB? That error usually occurs when the package for the mapping is missing from the DB or the parameters have changed.
Ignore above, just read properly, as MccM suggests try to compile package on DB to determine error. If there are no errors, refresh control center or close it and reopen it as it may be trying to call package with old set of parameters.
Si
Edited by: ScoobySi on Nov 30, 2010 4:20 PMExactly , I generated the mappings and then in the control center right clicking on the mappings and consider (default- create new) i deploy it. It goes ahead but tells mer there is a warning , which i already know but chose to ignore. Then i right click on the mappings again and I select start unfortunately at this point this error comes up and my DB doesnt get populated :( ...
I am a bit new so could you kindly go step by step here , how can i compile my package on DB ??? Btw i am using toad to connect to oracle 11g , are u suggesting that using toad i should compile the package ?? if so how ?? hwo would i know the package location ??? as for the second method
"If there are no errors, refresh control center or close it and reopen it as it may be trying to call package with old set of parameters." I doubt it will work as i already tried it. I definitely think there is a problem with the package.. i dont think there is any other problemm... I would really appreciate your help thanks...

ORA-06508 PL/SQL: could not find program unit being

Hi all,
I'm having the following problem: I have a trigger that gets fired before update of a field. The trigger source code calls a function from a package. This function calls another function.
When the trigger was executed I got the following error ORA-06508 PL/SQL: could not find program unit being call(referring to the second function called).
This trigger works well, but from time to time gets this error. (The database has a lot of users and there is a chance that more users fire the same trigger).
What can I do to solve this problem as it's very inconvenient? Any suggestions?
Thanks.

Try running the following query:
select *
from
v$db_object_cache
where sharable_mem > 10000
and type in ('PACKAGE','PACKAGE BODY','FUNCTION','PROCEDURE')
and KEPT='NO'
order by sharable_mem desc
See which objects are taking up a lot of SGA memory, you may need to pin them to prevent fragmentation. If you see DBMS_STATS in there it means that you Oracle is dynamically collecting stats which is not good - you need to set up a background task to do that.

Problem calling program unit function in Forms 6i

Hi,
I'm new to programming with Oracle Forms. I have a question that I cannot seem to figure out. In Forms 6i, I have created a program unit function that compiles correctly. The trouble I'm having is calling it and displaying the function's contents into a non-database display item I created. When I run my app, the display item it blank while my other fields populate.
I first tried to call it in a POST-QUERY trigger but I get an error stating "function cannot be called in SQL." Can you not call a function in a form's trigger? If so, what would be the correct syntax?
Then I tried to call it in the non-database item's Calculation => Formula (property) by just stating the function_name(parameter). This appears to compile fine too, but still no display at runtime.
What would be the best way to reference my function to display its contents properly? Does anyone have any examples? Any help would be greatly appreciated. Thank you.

First, get rid of the
EXCEPTION WHEN NO_DATA_FOUND
in your function. Summary queries never raise no_data_found; They just return null.
Your ":history.consecutive_years := NumberOfYears(:student.id);" is the proper way to call the function. That is what I was trying to tell you with the example: ':Myblock.Item_x := function_name(some_parm);' code
If your post-query trigger only executes the function, then I think your problem is somewhere else:
'FRM-40735 POST-QUERY trigger raised unhandled exception' looks like a problem elsewhere.
Don't know of a good website. Just keep asking here -- somebody is bound to pop in and help you out.
One more thing: drop this into your form-level on-error trigger. It often helps to find problems:
-- On-error form-level trigger                                       --*

Help with using Program unit.

How do I use a program unit. I am creating a procedure trying to understand how to use it.
I added 2 parameters to the layout. :P1_TEST and :P2_TEST
I created a simple program unit to place information into them
procedure test is
begin
:P1_TEST := 'YES';
:P2_TEST := 'NO';
end;.
When I run it nothing happens.
Howard

Hello,
The procedure must be callled in order to initialize the parameters.
In your case, you can call the procedure test in a Reports Trigger : the Before Report for example

Best Book on ORACLE SQL for a Beginner?

Hi friends ....I have just finished my graduation....(BE ELECTRONICS) .....I am dead serious about mastering ORACLE DATABASE......I have basic idea about ORACLE....Yesterday I just installed Oracle 10g Release 2 for VISTA...I just wanted to know which is the best book for a beginner who want to master ORACLE SQL....?????/

its Tutor as well.....But Last word.......Which is
"the" book for a beginner amongst all the SQL books
suggested by my dear friends........It ALL depends on what your short, medium and long range objectives are.
For example: do you want to be
- an Oracle DBA expert;
- an Oracle database programming expert;
- a general database programming expert with a specialty in Oracle;
- an Oracle application programming expert;
- a general application programming expert?
Personally I would encourage being a general database programming expert with a specialty in Oracle. This is probably the rarest of the group, the least understood, and the most needed in the industry. If you were to follow that path, I'd recommend a very very strong grounding in SQL - which 99% of all programmers I've met do NOT have - before moving forward to any procedural enhancement to SQL (such as PL/SQL, Java, TransactSQL, etc.)
I am the first to propose Tom Kyte's books in the right situations, which usually include:
- dealing with someone already reasonably competent in SQL and development;
- someone who thinks that porting from SQL Server to Oracle is a snap, since they are all 'just different dialects of SQL', or;
- someone who is seriously looking for guidelines on approaching Oracle application development and tuning.
For a complete beginner, my list of books stands in my preferred order (one at a time), with the addition - at the end - of Tom's books.

Urgent please : program unit in htmldb

Hi,
if I have some code that I will repeat in the same region,
is there in htmldb somwhere where I can store it and then
call it with parameters (like a program unit in oracle forms)
Thanks

Sergio,
Just curious, can a PL/SQL routine/process be written within an HTMLDB application which can be called from any page/process/validation from within the same application?
In our shop, to store packages/procedures, we need to get our DBA's involved. They would make sense if they were to be called from a myriad of applications. However, if a block of PL/SQL is going to be called many times within a single HTMLDB app and used nowhere else, this would be very handy.
Thanks Much,
Howard
