Writing own dml statements in jdeveloper

i need to write my own dml statement in a jdevelopers application. like on saving a purchase form i would like to update stock table as well. Some one told me to write code in DoDML procedure but how ? i mean what statement should i write there ?

lot of possibilities but easy way is to call PL/SQL code i guess you are coming from FORMS background so it would be easy and understandable for you
You can expose PL/SQL package as web-services also you can call stored procedures and functions in ADF
here is the example http://baigsorcl.blogspot.com/2010/05/calling-plsql-procedure-and-function-in.html
doDML() will work at entity level you can call your PL/SQL at doDML as well or as call its method binding

Will Materialized view log reduces the performance of DML statements on the master table

Hi all,
I need to refresh a on demand fast refresh Materialized view in Oracle 11GR2. For this purpose I created a Materialized view log on the table (Non partitioned) in which records will be inserted @ rate of 5000/day as follows.
CREATE MATERIALIZED VIEW LOG ON NOTES NOLOGGING WITH PRIMARY KEY INCLUDING NEW VALUES;
This table already has 20L records and adding this Mview log will reduce the DML performance on the table ?
Please guide me on this.

Having the base table maintain a materialised view log will have an impact on the speed of DML statements - they are doing extra work, which will take extra time. A more sensible question would be to ask whether it will have a significant impact, to which the answer is almost certainly "no".
5000 records inserted a day is nothing. Adding a view log to the heap really shouldn't cause any trouble at all - but ultimately only your own testing can establish that.

Inserting your own sql-statements in JSP

How do I use my own sql-statements in JSP combined with the ones
generated by JDeveloper?
It seems to me that the following sentences are the ones
generating the sql for inserting in a database:
<jbo:DataSource id="ds" appid="MimPKG.MimPKGModule"
viewobject="BidragView"/>
<jbo:Row id="newRow" datasource="ds" action="Create">
<jbo:SetAttribute dataitem="*"/>
</jbo:Row>
I would like to have more control and therefore I need to make
my own sql-statements.
Is that possible?
Thanks
Leise

You can use ExecuteSQL data tag to do so. It allows you to
include your own query like insert, update etc.

HR Schema DDL and DML Statements

Dear all,
I want all tables and datas for practicing purpose.(HR Schema)
In Oracle site where can I get these DDL and DML Statements.
Can Any one post all statements..
Thanks in advance.

Unlocking the Sample Tables
The Human Resources (HR) Sample Schema is installed as part of the default Oracle Database installation. The HR account is locked by default.
You need to unlock the HR account before you can use the HR sample schema. To unlock the HR account, log in as the SYSTEM user and enter the following command, where your_password is the password you want to define for the user HR:
ALTER USER HR IDENTIFIED BY your_password ACCOUNT UNLOCK;
For further information about unlocking the HR account, see the Oracle Database Sample Schemas guide. The HR user is primarily to enable you to access the HR sample schema and is necessary to enable you to run the examples in this guide.
Each table in the database is "owned" by a particular user. You may wish to have your own copies of the sample tables to use as you try the examples in this guide. To get your own copies of the HR tables, see your DBA or see the Oracle Database Sample Schemas guide, or you can create the HR tables with the script HR_MAIN.SQL which is located in the following directory on UNIX:
$ORACLE_HOME/DEMO/SCHEMA/HUMAN_RESOURCES/HR_MAIN.SQL
And on the following directory on Windows:
%ORACLE_HOME%\DEMO\SCHEMA\HUMAN_RESOURCES\HR_MAIN.SQL
To create the HR tables from command-line SQL*Plus, do the following:
1.
Ask your DBA for your Oracle Database account username and password.
2.
Login to SQL*Plus.
3.
On UNIX, enter the following command at the SQL*Plus prompt:
SQL> @?/DEMO/SCHEMA/HUMAN_RESOURCES/HR_MAIN.SQL
On Windows, enter the following command at the SQL*Plus prompt:
SQL> @?\DEMO\SCHEMA\HUMAN_RESOURCES\HR_MAIN.SQL
To remove the sample tables, perform the same steps but substitute HR_DROP.SQL for HR_MAIN.SQL.

DML statements in Function

Hi,
I have small question
Why we should not written DML statements in Function ?
Can any one explain that
Thanks...

Can any one explain thatThe answer is: "it depends".
Functions are used for many many different purposes, and it is the purpose that determines whether it's a good idea to write DML statements in a function.
As already mentioned, there are the purity rules, that basically say "if you're going to be calling the function from queries etc. then it cannot do DML, otherwise you'll get an exception"
But there are also functions that are intended to be used within PL/SQL code for other purposes. It may be that you need something that updates some data and returns a result from that updated data, or it returns how much data was effected, in which case it's perfectly ok to have a function do some DML.
As long as the code is well modularised and makes sense for the purpose for which it is intended, then you are doing the right thing. Where it goes wrong is when people lack design in their applications, and try to write 'generic' functions to be used in PL/SQL or SQL, or fail to modularise code so a function is doing the task of several things based on some parameters etc. when really each task should seperated to it's own functions/procedures etc.
So we cannot just say that we "should not" write DML inside functions; but we can say that there are design considerations (or lack of) when it would be bad practice to do so.

DML statements notification

Hello,
I have about 300 tables in my database, which is in oracle 9i. If any DML statements are done on these tables, I need a notification like, inserts a row to a notification table or creates a notification file. Writting trigger on all these tables is not possible. Is there are any other ways??

Writing triggers on each table should be possible if not practical. You discarded that idea so we'll explore another.
You might be able to create a system level trigger on the schema(s) in question. Check the Oracle documentation to see if the system trigger events support DML activity; they do support DDL activity.

If we use DML statement in function then that function can be used inside s

if we use DML statement in function then that function can be used inside select query or any DML query?

select f from t2;I think you meant to query t1.
It works if the function is an autonomous transaction:
create or replace function f return number
is
PRAGMA AUTONOMOUS_TRANSACTION;
begin
    update t1 set c=2;
    commit;
    return 1;
end;
select f from t1But as Billy said why would you want to do DML this way. And this is not the way autonomous procedures should be used either.
An an answer to an interview question though nothing wrong with it.

Problem in writing a Read Statement

Hi,
In my Table control I have a POSITION button which is used to find the record in the table.
I have written the following code.
CALL FUNCTION 'POPUP_GET_VALUES'
    EXPORTING
*   NO_VALUE_CHECK        = ' '
      popup_title           = 'Find the record'
*   START_COLUMN          = '5'
*   START_ROW             = '5'
* IMPORTING
*   RETURNCODE            =
    TABLES
      fields                = lt_tab
EXCEPTIONS
   error_in_fields       = 1
   OTHERS                = 2
I have five primary keys in my table, so that in the pop up I am getting all the five fields.
The user will enter any of the five fields , I want to write a read statement based on the fields entered by the user.
Could anybody help in writing the Read statement.
Or could any one help me in writing out the FIND functionality for a table control

Hi,
I do not know what fields will be filled up.
as there are 5 PK fields so 5! chances will be there for the where condition in the READ statement.
How can I do it.
I tried in the following way.
I created a structure with the primary key fields and I filled the structure with the user filled values.
Then I used it in the read statement as below, but it did not work.
    LOOP AT lt_tab .
      IF lt_tab-fieldname = 'SOCIEDAD'.
        lw_pk-sociedad = lt_tab-value.
      ENDIF.
      IF lt_tab-fieldname = 'NATURAL_YEAR'.
        lw_pk-natural_year = lt_tab-value.
      ENDIF.
      IF lt_tab-fieldname = 'CICLO_DE_VENTAS'.
        lw_pk-ciclo_de_ventas = lt_tab-value.
      ENDIF.
      IF lt_tab-fieldname = 'MODEL_VERSION'.
        lw_pk-model_version = lt_tab-value.
      ENDIF.
    ENDLOOP.
    DATA:lw_yrwbw010 TYPE ty_yrwbw010.
    READ TABLE t_yrwbw010 INTO lw_yrwbw010 WITH KEY lw_pk.
     IF sy-subrc = 0.
      table-top_line = sy-tabix.

Can we do Dml statements on materialize views

I want to know can we do Dml statements on materialize views .If yes, how

Can you? Maybe. Depends on how you created the materialized view. Should you? Maybe. Are you running a multi-master environment? Or are you using materialized views for one-way replication? If you are doing one-way replication, do you want your DML changes to be retained beyond the next refresh of the materialized view?

Almost ok but how you will handle the overlapping (transactions captured by expdp & captured by Extract too) of transactions for the new table ?
Metalink doc ID 1332674.1 has the complete steps. Follow the "without HANDLECOLLISIONS" approach.

How to monitor DML statements

Hi pals,
I want to know how i can monitor DML statements, i can able to monitor select statments but don't DML statements, is there any way or script in following format:
Executer,Statement,%Completed,%left,Exec_Time,Time_left
Where
Executer is a user who runs the statement
Statement which statement runs
%completed how much DML operation completed
%left how much DML operation left
Exec_Time elapsed time
time_left how much time remaining in complete operation
I really apperciate you pals if you can give me some idea how this can be possible??
Thanks in advance

Hi,
These info can be found in V$SESSION_LOGOPS. But the view isn't populated for every query and sometimes it's a bit weird (I actually had queries that ouput 290% of "work" - parallel query side effect). Also notice that this is for long ops, and not everything will be reported there.

How to Split ddl or dml statement

Hi guys,
i'm using oracle 11.2
i've the following question.
i've a string that can contains multiple ddl or dml statement and i need to split them in more statement.
i.e. i can have a string like the below and i need 2 string each one with a statement:
insert into TEST_KIT_USER1.table1 values (1,'a');
insert into TEST_KIT_USER1.table1 values (2,'b');
otherwise i can have a string like the below and i need 2 string each one with a statement:
create table TEST_KIT_USER1.table2
name char(10),
surname CHAR(10 BYTE)
create table TEST_KIT_USER1.table3
id number,
description CHAR(10 BYTE)
is there a simple way to do this?

Have you tried using iMovie?
I know that iMovie HD '06 can do this, I'm not sure if '08 can.

Constructing Database Update DML Statements

This is a very common problem I am sure but want to know how others handle it. I am creating a web application via Servlets and JSPs. I am working with Oracle 10g.
Here's the problem/question.
When I present an html form to a user to update an existing record, how do I know what has changed in the record to create the dml statement? I could just update the entire record with the values supplied via the POST data on submit but that does not seem right since maybe only 1 out of 10 fields actually changed. This would also write needless audit and logging information to the database. I have thought about comparing the Request parameters sent with the post with the original java bean used to populate the form in the first place by adding it back to the request as an attribute. Is this the only way to do it or is there a better way?
Thanks everyone,
-Brian

What database drivers are you using? I recall there being some bug in
sp2 that caused delayed transaction commits for a very specific
combination of transaction settings and database drivers.
I think it was third-party type II Oracle drivers and local
transactions, but I'm not sure.
In any case, I'd contact support as there is a patch available.

Hi all,
I have posted something of this sort earlier too. The problem is that
the database is not reflecting what has been updated using queries from the
application.
THe structure of the application is as follows.
DB = Oracel 8.1.6
Web Server = iPlanet 4.0
App Server = iPlanet 6.0 sp2
The database is connected to via the EJB's. No Database transactions are
being used except for Bean transactions which are container managed. The
setAutoCommit flag is set to true. Each query is a transaction. The jsp's
call these ejb's through wrapper classes. As stated earlier the database
updates (Inserts, update, delete statements) are not getting reflected in
the database immediately. The updates happen after a gap of about 7-10
minutes. Why is this sort of behaviour coming up. This is almost like batch
updates happening on the database. Is there a setting in IPlanet for
removing this kind of problem.
