Update beans after adding columns to DB tables

I am trying to use JDeveloper 10G , Studio Edition Version 10.1.3.0.4.3673
I am having difficulty finding out how to update CMP Entity Beans
after adding columns to DB tables.
I have found descriptions of how to do these from four sources.
None of these methods work.
They all refer to menu options, buttons or fields that aren't in the JDevb IDE.
List of options that don't exist :
"Synchronize with Database"
"attributes"
"Add from table"
"New from Table"
"Fields Tab"

What version of EJBs are you using?
The only option I know of for EJBs will be to generate the bean from the table again, or manually add the field to the EJB.
The "Synchronize with Database" operation is there for ADF Business Components but not for EJBs.

Is it necessary to update scope_info and scope_config when adding columns to a table in a provisioned database?

I followed the example provided in
https://jtabadero.wordpress.com/2011/04/13/modifying-sync-framework-scope-definition-part-3-workarounds-addingremoving-columns/ to add columns to a table in a provisioned database. The sample code replaces the stored procedures triggered when the
table is updated with new stored procedures which include the additional columns
However, the sample does not update scope_config. When I am finished, the new columns do not appear in the scope config. Looking at the SQL code it is immediately obvious why. Here is an excerpt from the beginning of the query
DROP PROCEDURE [PATIENT_insertmetadata];
DROP PROCEDURE [PATIENT_updatemetadata];
DROP PROCEDURE [PATIENT_deletemetadata];
-- BEGIN Enable Snapshot Isolation on Database 'PatScan' if needed
IF EXISTS (SELECT NAME FROM sys.databases where NAME = N'PatScan' AND [snapshot_isolation_state] = 0)
BEGIN
ALTER DATABASE [PatScan] SET ALLOW_SNAPSHOT_ISOLATION ON
END
GO
-- END Enable Snapshot Isolation on Database 'PatScan' if needed
-- BEGIN Create Scope Info Table named [scope_info]
IF NOT EXISTS (SELECT t.name FROM sys.tables t JOIN sys.schemas s ON s.schema_id = t.schema_id WHERE t.name = N'scope_info' AND s.name = N'dbo')
BEGIN
CREATE TABLE [scope_info] ([scope_local_id] int IDENTITY(1,1) NOT NULL, [scope_id] uniqueidentifier DEFAULT NEWID() NOT NULL, [sync_scope_name] nvarchar(100) NOT NULL, [scope_sync_knowledge] varbinary(max) NULL, [scope_tombstone_cleanup_knowledge] varbinary(max)
NULL, [scope_timestamp] timestamp NULL, [scope_config_id] uniqueidentifier NULL, [scope_restore_count] int DEFAULT 0 NOT NULL, [scope_user_comment] nvarchar(max) NULL)
ALTER TABLE [scope_info] ADD CONSTRAINT [PK_scope_info] PRIMARY KEY ([sync_scope_name])
END
GO

IF NOT EXISTS (SELECT t.name FROM sys.tables t JOIN sys.schemas s ON s.schema_id = t.schema_id WHERE t.name = N'scope_config' AND s.name = N'dbo')
BEGIN
CREATE TABLE [scope_config] ([config_id] uniqueidentifier NOT NULL, [config_data] xml NOT NULL, [scope_status] char NULL)
ALTER TABLE [scope_config] ADD CONSTRAINT [PK_scope_config] PRIMARY KEY ([config_id])
END
GO
-- END Create Scope Config Table named [scope_config]
In an already provisioned database, the scope_info and scope_config tables already exist. Hence the portions of the script to create the scope_info and scope_config tables are skipped. I tried modifying the query to drop these tables. When
I do so, ne tables are created but they only define the modified table.
Is it necessary to update scope_info and scope_config? Are there are side effects (such as deprovisioning) if I drop and then recreate these tables? Can I just update the existing scope_config, replacing the portion of the XML which defines the table
being modified? Do I have to make changes in scope_info?
Thanks

Can I update 2(or multiple) columns in a table based on one of update col?

Hi All,
I have a table emp:
empno number
,salary number
,comm number
Now, the comm column is always a % of the salary column (but still would like to store the comm in the table as a column).
Assuming that someone get a salary increment and I need to update the commission as well based on the new salary value, should I still use 2 update statements or is there anyway, I can achive in a single update clause itself?
example:
if the old values were:
=============
1234 10000 1000
and if I do the following,
update emp
set salary = salary + 3000
,comm = salary * 10/100
where empno = 1234;
the comm value still points to the old salary value and the table looks like:
emp:
===
1234 13000 1000
instead of:
1234 13000 1300 (10% of the new salary - 13000)
so, the only way to achieve this is to issue 2 update statements? Or is there any way of achieving in one single update statement? Please let me know.
Am on Oracle 10.2.0.3.0.
Thanks,
Srini.

Or you could create a after update trigger on salary column that updates comm whenever Sal updates.
What happens if someone else issues an update on salary and forgets to update the commission? Wont you have incorect data then?
Also, commision is a redundant column . I dont think it is a good idea to have computed values as a separate column.
Thanks,
Rajesh,

Newly added column in a table not displayed in a related form

I added a new column (DNAMECONT as varchar2) in a table I created a Form on. I added this new field in my Form as a text field, and on the customized tab of the form wizard, this following code is displayed as expected :
<TR><TD><#DCONTRACTOR.LABEL#></TD><TD><#DCONTRACTOR.ITEM#></TD></TR>
But I cannot view it once I run my form.
did I forget to do something or is there something I did wrong?
Thank you for your help.
Bertrand

Sorry to interupt, as far as I understand, if you add extra column to a table after the form is built and you want to add this new column in your form. When you add new item in your form, the name you give to the item should exactly match the column name of your new column of the table. Now, you said you added a new column called DNAMECONT, but the
html shown in form wizard is <#DCONTRACTOR.LABEL#>, <#DCONTRACTOR.ITEM#>, two names do seem to match. Is that the problem?

General Scenario- Adding columns into a table with more than 100 million rows

I was asked/given a scenario, what issues do you encounter when you try to add new columns to a table with more than 200 million rows? How do you overcome those?
Thanks in advance.
svk

For such a large table, it is better to add the new column to the end of the table to avoid any performance impact, as RSingh suggested.
Also avoid to use any default on the newly created statement, or SQL Server will have to fill up 200 million fields with this default value. If you need one, add an empty column and update the column by using small batches (otherwise you lock up the whole
table). Add the default after all the rows have a value for the new column.

SSAS Tabular - Adding Column to a table gives error "Object reference not set to instance of object"

If I make changes to a table in SSAS Tabular Visual Studio, the newly added column gives error as "Object
reference not set to instance of object"

Hi VikasJain13,
According to your description, you get the "Object reference not set to instance of object" error when adding columns in Tabular. Right?
Generally, it throws this error when the internal code is accessing the property of an empty object. As you mentioned it happens when you make changes on a table, mostly it means that table is already a empty object. Please re-process your tabular to see
if this table is still existing.
If you have any question, please feel free to ask.

Adding column to a table

Hi everybody,
I have to make a column (in Siebel repository) or better to say I have to add a column to the table. The column doesn't exist in a database. There is a PL/SQL package which has the stored procedure I need to call to make column. How may I make the column from the stored procedure?
Thanks in advance.
I apologize if the meaning from the above sentences is confused.

How to Update the oracle toad column value in table by using SSRS 2008

Hi Team,
How to update the oracle DB table column value by using SSRS 2008.
Can any one help me on this.
Thanks,
Manasa.
Thank You, Manasa.V

Hi veerapaneni,
According to your description, you want to use SSRS to update data in database table. Right?
Though Reporting Services is mostly used for rendering data, your requirement is still can be achieved technically. You need to create a really complicated stored procedure. Pass insert/delete/update and the columns we need to insert/delete/update as
parameters into the stored procedure. When we click "View Report", the stored procedure will execute so that we can execute insert/delete/update inside of the stored procedure. Please take a reference to two related articles below:

Problems adding columns in a table

Hi,
I defined a table. Now I need to add new columns. In OWB I set them in their correct order but when I deploy the table with upgrade, in the database, columns appear at the end of the table.
Does anyone know this problem, how can i resolve this?
Thanks
Beatriz

You mean ordered in the table as shown in a mapping or table editor window? This ordering is only visual and will not impact meta-data definition.
If it is really important the best solution is to:
- replace the table with new/altered columns by script in SQLplus/Toad
- do import of table in OWB (mention the 'Advanced Reconciliation Options' uncheck the 'Preserve...' boxes)
- reconcile inbound in a mapping where the table is used. Lines to columns will stay if the column-name didn't change.
Anybody know this issue is solved in OWB 10g R2?

Add columns to a table with lob column

Hi,
Just a quick question: is there a performance penalty after adding columns to a table with a lob fied? the lob field is now the last column in the table and via via I was told that adding columns will impact badly the IO performance on the table if the lob field isn't anymore the last column. The table is on a Oracle 10.2.0.3 version.
thanks. regards
Ivan

Havent heard of performance degradation specifically due to a LOB column not being the last column in a table (although there are several issues with just having a LOB column in a table).
You may want to build a test database to test it out. It should be easy to run tests comparing one with the additional column and one the original to prove or refute it. The results would be interesting to learn - please post them up if you intend to test it out.

How to update multiple columns from different tables using cursor.

Hi,
i have two tables test1 and test2. i want to udpate the column(DEPT_DSCR) of both the tables TEST1 and TEST2 using select for update and current of...using cursor.
I have a code written as follows :
DECLARE
v_mydept1 TEST1.DEPT_CD%TYPE;
v_mydept2 TEST2.DEPT_CD%TYPE;
CURSOR C1 IS SELECT TEST1.DEPT_CD,TEST2.DEPT_CD FROM TEST1,TEST2 WHERE TEST1.DEPT_CD = TEST2.DEPT_CD AND TEST1.DEPT_CD = 'AA' FOR UPDATE OF TEST1.DEPT_DSCR,TEST2.DEPT_DSCR;
BEGIN
OPEN C1;
     LOOP
          FETCH C1 INTO v_mydept1,v_mydept2;
          EXIT WHEN C1%NOTFOUND;
          UPDATE TEST2 SET DEPT_DSCR = 'PLSQL1' WHERE CURRENT OF C1;
          UPDATE TEST2 SET DEPT_DSCR = 'PLSQL2' WHERE CURRENT OF C1;
     END LOOP;
     COMMIT;
END;
The above code when run says that it runs successfully. But it does not updates the desired columns[DEPT_DSCR].
It only works when we want to update single or multiple columns of same table...i.e. by providing these columns after "FOR UPDATE OF"
I am not sure what is the exact problem when we want to update multiple columns of different tables.
Can anyone help me on this ?

oops my mistake.....typo mistake...it should have been as follows --
UPDATE TEST1 SET DEPT_DSCR = 'PLSQL1' WHERE CURRENT OF C1;
UPDATE TEST2 SET DEPT_DSCR = 'PLSQL2' WHERE CURRENT OF C1;
Now here is the upated PL/SQL code where we are trying to update columns of different tables --
DECLARE
v_mydept1 TEST1.DEPT_CD%TYPE;
v_mydept2 TEST2.DEPT_CD%TYPE;
CURSOR C1 IS SELECT TEST1.DEPT_CD,TEST2.DEPT_CD FROM TEST1,TEST2 WHERE TEST1.DEPT_CD = TEST2.DEPT_CD AND TEST1.DEPT_CD = 'AA' FOR UPDATE OF TEST1.DEPT_DSCR,TEST2.DEPT_DSCR;
BEGIN
OPEN C1;
LOOP
FETCH C1 INTO v_mydept1,v_mydept2;
EXIT WHEN C1%NOTFOUND;
UPDATE TEST1 SET DEPT_DSCR = 'PLSQL1' WHERE CURRENT OF C1;
UPDATE TEST2 SET DEPT_DSCR = 'PLSQL2' WHERE CURRENT OF C1;
END LOOP;
COMMIT;
END;
Please let us know why it is not updating by using using CURRENT OF

Setting a Primary Key for a newly added Column

Is it possible for setting a primary key for a newly added column in a table having records?

Hi,
km**** wrote:
oh if the table has records then it is not possible ah...No, the table can have rows at the time you add the Primary Key constraint. Solomon was just saying that the column(s) that you are making into the Primary Key must already have unique values. A Primary Key can not be NULL, so you must do the steps in this order:
(1) ALTER TABLE to add the column(s) (if this hasn't been done already)
(2) UPDATE the table, to put unique values in all rows for the Primary Key column(s)
(3) Add the PRIMARY KEY constraint
You need to do step (2) before you do step (3)

Updating statistics after insert

Is it possible, without creating a custom post-map process, to update statistics after inserting rows into a table. I've tried setting different parameters within OWB to no avail.
Please respond only if you have actually succeeded in updating statistics without writing code. I've already read the docs and experimented.
Thanks.
Garrett

Hi,
why do you think so? The analyze configuration
results in a procedure which calls
WB_RT_MAPAUDIT_UTIL_INVOKER for each target table
which then calls the DBMS_STATS-Package? What is
misssing for the CBO? I'm a little bit confused?!
Regards,
DetlefThanks for the info. I'm a little confused. I thought that I had the analyze table box checked in the configuration and statistics were not updated. However, when I looked again, it was not checked. My error. Ran another test and statistics were updated. Sorry for the confusion.
