Tabular Form Page - Insert and Update Primary Key

Hi -
I am creating a Tabular Form page which will display 2 columns:
CODE (Text Field), DESCRIPTION(Field)
The *'CODE'* is a primary key to the table/view and *'DESCRIPTION'* is the corresponding detail information for the *'CODE'*.
I am trying to create an updateable report on this page which will show these columns and when a user wants to add a new row,they should be able to add a new row with CODE='somecode' and DESCRIPTION='description' but shouldn't be able to update (but should be displayed) the *'CODE'* value once inserted into the table or view.
Is there a way to do that? Please share your expertise.
Thanks,
-Seenu

I't a bit unclear what you want.
In your first post it seems that you don't want the user to change the PK.
In your second post the user can change the PK, but you get a db error.
Anyway, I guess you don't want the user to change the PK.
I have a few support tables, which are the source for some LOV's.
For those I also add records with a manual assigned PK, rather then via a sequence, just to improve consistency across applications.
The data is protected by foreign keys to the main tables.
You could further add a trigger to your table which throws an error the moment it detects a change on your PK.

Tabular Form on Table with no primary key

I have many tables defined with Unique Index (instead of Primary Keys). This allows my user to update/insert the value of the unique index. When I try to create my form in HTML DB, it makes me put in the primary key. If I choose th column that has the unique index, it will not let me update or insert that value. How can I achieve this?

Create a surrogate PK called rec_id or something and populate that using a BEFORE INSERT row-level trigger
create sequence pk_seq;
create or replace trigger trg
before insert on t
for each row
begin
select pk_seq.nextval into :new.rec_id from dual;
end;
/Tell the HTML DB wizard about this new PK (rec_id), should work fine
Hope this helps.

Oracle forms 10g,multiple insert and update problem

Hi,
I have tabular form(4 records displayed) with one datablock(based on a view).
After querying the form could not update all the records but only first record value can select from LOV.
I called a procedure in in-insert and on-update
The query is lik this
PACKAGE BODY MAPPING IS
     PROCEDURE INSERT_ROW(EVENT_NAME IN VARCHAR2)
     IS
     BEGIN
          IF (EVENT_NAME = 'ON-INSERT') THEN
               INSERT INTO XX_REC_MAPPING
               (BRANCH_CODE,COLLECTION_ID,PAY_MODE_ID,RECEIPT_METHOD,CREATED_BY,
               CREATION_DATE,LAST_UPDATED_BY,LAST_UPDATE_DATE,LAST_UPDATE_LOGIN)
               VALUES
               (     :XX_REC_MAPPING.OFFICE_CODE,
                    :XX_REC_MAPPING.COLLECTION_ID,

          END IF;
     END INSERT_ROW;
END MAPPING;
Whether the table gets looked or sholud i use some other trigger or loops ?
someone suggest me how to edit this query for multiple update.
Thanks

I called a procedure in in-insert and on-updateWhy are you writing this code in the first place? If you have a block based on an updatable view, just let Forms do the inserts and updates.
If it's not an updatable view, use instead of triggers on the view.
See this current thread too:

Update primary key/delete and reinsert records

Hi, I have been told to update some fields. The database is new to me, and now I see the field is the primary key (and it has child tables with that as foreign key). The person who told me isn't reachable until next week...
...wasn't a bad idea to update pk's? I see it's possible, deferring constraints...
update primary key
Re: Update Primary Key
...but it's better/safer the script deletes and later re-insert the records, right?
Thanks

Always is better be able to undo any change .
But ¡, why would you update pk's? it's possible but you colud find few problems like:
- many levels of foreign keys exists.
- not validate pk
Look at:
Re: Novalidate primary key

Getting the UPDATEd value and its primary key

I have two procedures, proc1 and proc2.
In proc1 there is an update happening like
CREATE OR REPLACE procedure proc1
as
TYPE NumList IS TABLE OF employees.employee_id%TYPE;
enums NumList;
TYPE NameList IS TABLE OF employees.last_name%TYPE;
names NameList;
BEGIN
UPDATE emp set sal=900 WHERE department_id = 30
RETURNING employee_id, last_name BULK COLLECT INTO enums, names;
DBMS_OUTPUT.PUT_LINE('Updated ' || SQL%ROWCOUNT || ' rows:');
FOR i IN enums.FIRST .. enums.LAST
LOOP
DBMS_OUTPUT.PUT_LINE('Employee #' || enums(i) || ': ' || names(i));
END LOOP;
END;
/In proc2 which is getting executed just after proc2 i want to SELECT the sal column values and its primary keys(employee_id) which got updated in proc 1.
How can i achieve this?

add two out parameters from proc1 so that you can pass them into proc2 (obv. you'd need to add two in parameters to proc2 if they aren't there already)

How to make the Tabular Form for Inserting records only?

Can we use both INSERT and UPDATE at the same time in JDBC Receiver

Hi All,
I would like to know is it possible to use both INSERT and UPDATE at the same time in one interface because I have a requirement in which I have to perform both the task.
user send the file which contains both new and old record and I need to save those in MS SQL database.
If the record exist then use UPDATE otherwise use INSERT.
I looked on sdn but didn't find any blog which perform both the things at the same time.
Interface Requirement
FILE -
> PI -
> JDBC(INSERT & UPDATE)
I am thinking to use JDBC Lookup but not sure if it good to use for bulk record.
Can somebody please suggest me something or send me the link of any blog or anything to solve this problem.
Thanks,

Hi ,
          If I have understood properly the scenario properly,you are not performing insert and update together. As you posted
"If the record exist then use UPDATE otherwise use INSERT."
Thus you are performing either an insert or an update which depends on outcome of a search if the records already exist in database or not. Obviously to search the tables you need " select * from ... where ...." query. If your query returns some results you proceed with update since this means there are some old records already in database. If your query returns no rows you proceed with "insert into tablename....." since there are no old records present in database.
Now perhaps the best method to do the searching, taking a decision to insert or update, and finally insert or update operation is to be done by a stored procedure in MS SQL database. A stored procedure is a subroutine available to applications accessing a relational database system. Here the application is PI server.   If you need further help on how to write and call stored procedure in MS SQL you can look into these links
http://www.daniweb.com/web-development/databases/ms-sql/threads/146829
http://www.sqlteam.com/article/stored-procedures-parameters-inserts-and-updates
[ This part you can ignore, Since its not sure that you will face this situation
    Still you might face some problems while your scenario runs. Lets consider this scenario, after the stored procedure searches the database it found no rows. Thus you proceed with an insert operation. If your database table is being accessed by multiple applications (or users) other than yours then it is very well possible that after the search operation completed with a null result, an insert/update operation has been performed by some other application with the same primary key. Now when you are trying to insert another row with same primary key you get an error message like "duplicate entry not possible for same primary key value". Thus you need to be careful in this respect. MS SQL has a feature called "exclusive locks ". Look into these links for more details on the subject

http://www.mollerus.net/tom/blog/2008/03/using_mssqls_nolock_for_faster_queries.html
    There must be other methods to avoid this problem. But the point is you need to be sure that all access to database for insert/update operations are isolated.

Kindly Regards...

You might be better off combining into your attack the use of user_dependencies. This will tell you what objects e.g., code is dependent on your table and then you can search the source of those modules for inserts and updates into the table. Even then you'll never be sure, especially if dynamic SQL is used as the statement may be pieced together from various bits if strings, as then user_dependencies won't contain the reference.

"reproc: Insert and Update failed on" replicated table

Hello, I've published a new publication item on an Oracle Lite Server (9i and mobile server 5.0.2.10).
After inserting records on the server replicated table (Table1), when I try to sync some devices, I have the following error message on the client PDA "reproc Insert and Update failed on " Table1.
If I empty the server table's records, then the client PDA syncs OK.
Can someone refresh me with the cause of this error ?
Thank's in advance.
Regards,

Hi,
This is my actual requirement.
During the updates i.e update process and delete process, if the filed status is changed to 'O', '0' or ' ' in SAP, then those records in Oracle should be deleted.
if the field status is changed to other than 'O', '0', or ' ' SAP, then those records needs to be updated with the remaining information
How do XI Know that these fields are changed in the SAP table to perform delete ,is some notification required when there is change in SAP Table through proxy ?
