Delete 50 Million records from a table with 60 Million records

Hi,
I'm using oracle9.2.0.7 on win2k3 32bit.
I need to delete 50M rows from a table that contains 60M records. This db was just passed on to me. I tried to use the delete statement but it takes too long. After reading the articles and forums, the best way to delete that many records from a table is to create a temp table, transfer the data needed to the temp table, drop the big table then rename temp table to big table. But the key here is in creating an exact replica of the big table.I have gotten the create table, indexes and constraints script in the export file from my production DB. But in the forums I read, I noticed that I haven't gotten the create grant script, is there a view I could use to get this? Can dbms.metadata get this?
When I need to create an exact replica of my big table, I only need:
create table, indexes, constraints, and grants script right? Did I miss anything?
I just want to make sure that I haven't left anything out. Kindly help.
Thanks and Best Regards

Can dbms.metadata get this?
Yes, dbms_metadata can get the grants.
YAS@10GR2 > select dbms_metadata.GET_DEPENDENT_DDL('OBJECT_GRANT','TEST') from dual;
DBMS_METADATA.GET_DEPENDENT_DDL('OBJECT_GRANT','TEST')
GRANT SELECT ON "YAS"."TEST" TO "SYS"
When I need to create an exact replica of my big table, I only need:
create table, indexes, constraints, and grants script right? Did I miss anything?
There are triggers, foreign keys referencing this table (which will not permit you to drop the table if you do not take care of them), snapshot logs on the table, snapshots based on the table, etc...

Select max date from a table with multiple records

I need help writing an SQL to select max date from a table with multiple records.
Here's the scenario. There are multiple SA_IDs repeated with various EFFDT (dates). I want to retrieve the most recent effective date so that the SA_ID is unique. Looks simple, but I can't figure this out. Please help.
SA_ID CHAR_TYPE_CD EFFDT CHAR_VAL
0000651005 BASE 15-AUG-07 YES
0000651005 BASE 13-NOV-09 NO
0010973671 BASE 20-MAR-08 YES
0010973671 BASE 18-JUN-10 NO

Hi,
Welcome to the forum!
Whenever you have a question, post a little sample data in a form that people can use to re-create the problem and test their ideas.
For example:
CREATE TABLE     table_x
(     sa_id          NUMBER (10)
,     char_type     VARCHAR2 (10)
,     effdt          DATE
,     char_val     VARCHAR2 (10)
INSERT INTO table_x (sa_id, char_type, effdt,                          char_val)
     VALUES     (0000651005, 'BASE',    TO_DATE ('15-AUG-2007', 'DD-MON-YYYY'), 'YES');
INSERT INTO table_x (sa_id, char_type, effdt,                          char_val)
     VALUES     (0000651005, 'BASE',    TO_DATE ('13-NOV-2009', 'DD-MON-YYYY'), 'NO');
INSERT INTO table_x (sa_id, char_type, effdt,                          char_val)
     VALUES     (0010973671, 'BASE',    TO_DATE ('20-MAR-2008', 'DD-MON-YYYY'), 'YES');
INSERT INTO table_x (sa_id, char_type, effdt,                          char_val)
     VALUES     (0010973671, 'BASE',    TO_DATE ('18-JUN-2010', 'DD-MON-YYYY'), 'NO');
COMMIT;Also, post the results that you want from that data. I'm not certain, but I think you want these results:
`    SA_ID LAST_EFFD
    651005 13-NOV-09
10973671 18-JUN-10That is, the latest effdt for each distinct sa_id.
Here's how to get those results:
SELECT    sa_id
,         MAX (effdt)    AS last_effdt
FROM      table_x
GROUP BY sa_id

Issue with fetching a record from IHPA table with PARNR value as condition

Hi All,
I am trying to fetch a particular record from IHPA table where i am giving the OBJNR number, PARVW and PARNR as customer no. , But I am not getting any record but if i will give OBJNR and PARVW it will generate a record with having same PARNR value.
Example :
case 1st :-
when i am passing following values in IHPA table,
OBJNR = IE000000000010070910
PRAVW = BP
PARNR = 620000562
it is not generating any record
case 2nd:-
But if i will pass
OBJNR = IE000000000010070910
PRAVW = BP
it will generate a record?(one row) which will include PARNR as same 620000562 along with other value.
Q1 - Why it's not generating in case 1st,
Q2 - How I will resolve this issue ? as i have to link some table as EQUI -
IHPA -
VCKUN
VCNUM ?
      I have written a code for this to join :
     SELECT A~EQUNR
       B~PARVW
       C~CCNUM
       D~CCNUM
       FROM EQUI AS A JOIN IHPA AS B ON AOBJNR = BOBJNR
       INNER JOIN VCKUN AS C ON BPARNR = CKUNNR
       INNER JOIN VCNUM AS D ON CCCNUM = DCCNUM
       APPENDING CORRESPONDING FIELDS OF TABLE IT_OBSO
       WHERE A~EQUNR IN S_EQN.
             AND PARVW = 'BP'.
      But it is not generating any record but when i am commenting the PARVW i am getting the mixed record of PARVW as (BP,SP,SH)
Let me know if any more clarification required.
Highly appreciate your help
Thanks & Regards
Shaw

Hi Santosh,
Thanks for your quick response.
But I am Sorry, I already checked with putting Zero before PARNR.
The issue is still as it is.
Thanks

How can i get all the records from three tables(not common records)

Hi
I have four base tables at R/3-Side. And i need to extract them from R/3-Side.
And i dont have any standard extractor for these tables .
If i create a 'View' on top of these tables. Then it will give only commom records among the three tables.
But i want all the records from three base tables (not only common).
So how can i get the all records from three tables. please let me know
kumar

You can create separate 3 datasources for three tables and extract data to BW. There you can implement business login to build relation between this data.

Issue in retrieving all the records from ADF Table with multiple row

Hi,
As per my requirement, I need to fill the table with multi selected LOV values and when user clicks on commit, I need to save them to database.
I am using ADF 11g, Multi select table. Using the below ADD method, I am able to add the records but if user clicks on cancel, I need to remove those from view and clear the table as well.
But the Issue I am facing is, in my cancel method, always I am getting half of the records. Lets assume table contains 100 records but in my cancel method, I am getting only 50 records.
Please let me know what is the issue in my source code.

Value Set whose Data come from customize table with distinct record

Dear All,
I am new in Oracle EBS, currently i am creating value set whose data come from customize table which have 40 duplicate record in which distinct column return 27 record .
Table XX_ROUND_SET
Columns (Transactions_id,set_record)
Total Record (40)
Distinct Record (Set_Record --> 27)
I just want to show only 27 record in it.
Thanks
Rehan

Hi Rehan,
PL.IGNORE MY EARLIER UPDATE AND TREAT THIS UPDATE AS YOUR SOLUTION.
Method 1
Create the VIEW based on DISTINCT values; use the VIEW for creates the VALUESET.
Method 2
Paste the QUERY in TABLE field with alias name, and give the column name (with alias name).
(in your case )
TABLE NAME : ( select distinct transactions_id, set_record from XX_ROUND_SET ) Y
VALUE : Y.transactions_id

How can i fetch records from 3 tables in a single query without using join

Hi.
Can any body please tell me <b>How can i fetch records from 3 tables with a single query without using joins</b>
Thanx
prabhudutta

Hi Prabgudutta,
We can fetch the data by using the views concept.
Go throuth this info we can know the how to create view and same like database table only we can fetch the data.
Views conatin the data at runtime only.
Four different view types are supported. These differ in the
way in which the view is implemented and in the methods
permitted for accessing the view data.
Database views are implemented with an equivalent view on
the database.
Projection views are used to hide fields of a table (only
projection).
Help views can be used as selection method in search helps.
Maintenance views permit you to maintain the data
distributed
on several tables for one application object at one time.
step by step creation of Maintenance view:
With the help of the table maintenance generator, you are able to maintain the ENTRIES of the table in SM30 transaction.
It can be set in transaction SE11 - Tools - Table maintenance generator.
Table maintanance Generator is used to manually input values using transaction sm30
follow below steps
1) go to se11 check table maintanance check box under attributes tab
2) utilities-table maintanance Generator-> create function group and assign it under
function group input box. Also assign authorization group default &NC& .
3) select standard recording routine radio in table table mainitainence generator to move table
contents to quality and production by assigning it to request.
4) select maintaience type as single step.
5) maintainence screen as system generated numbers this dialog box appears when you click on create button
6) save and activate table
One step, two step in Table Maintenance Generator
Single step: Only overview screen is created i.e. the Table Maintenance Program will have only one screen where you can add, delete or edit records.
Two step: Two screens namely the overview screen and Single screen are created. The user can see the key fields in the first screen and can further go on to edit further details.
SM30 is used for table maintenance(addition or deletion of records),
For all the tables in SE11 for which Table maintenance is selected , they can be maintained in SM30
Sm30 is used to maintain the table ,i.e to delete ,insert or modify the field values and all..
It creates the maintenance screen for u for the aprticular table as the maintenance is not allowed for the table..
In the SE11 delivery and maintenance tab, keep the maintenance allowed..
Then come to the SM30 and then enter the table name and press maintain..,
Give the authorization group if necessary and give the function group and then select maintenance type as one step and give the screen numbers as system specified..
Then create,,,
Then u will able to see the maintenance view for the table in which u can able to insert and delete the table values...
We use SM30 transaction for entering values into any DB table.
First we create a table in SE11 and create the table maintenance generator for that Table using (utilities-> table maintenance generator) and create it.
Then it will create a View.
After that from SM30, enter the table name and Maintain, create new entries, change the existing entries for that table.
Hope this resolves your query.
Reward all the helpful answers.

Delete many rows from one table at once URGENT

Assume we have table called emp.

9999-----------------044-------------9191--------------03/05/1980
9999-----------------055-------------9191--------------03/06/1989
My goal is to delete employee records for those employee which contains multiple values for JOB_NO
equal to 8181, (JOB_NO= 8181) with new start_dateS.
We need to keep only one record for JOB_NO 8181 which contains oldest start_date.
Here is the delete statement for the single record.
delete from emp
where empno = 7777 and job_no = 8181 and start_date in ('03/01/2002','06/24/1996);
So how could I delete thousands records from the table with this logic?
After deleting multiple records table should be as below:
select * from emp;
EMPNO--------DIVISION--------JOB_NO---------START_DATE
1111-----------------011-------------8181--------------04/10/1999
2222-----------------011-------------3131--------------05/11/2005
3333-----------------044-------------8181--------------06/08/1988
5555-----------------011-------------8066--------------01/01/2001
6666-----------------033-------------9600--------------01/01/1999
7777-----------------033-------------8181--------------12/02/1991
9999-----------------044-------------9191--------------03/05/1980
9999-----------------055-------------9191--------------03/06/1989

Here's one way to do it. I think this fits your business rules. At least it matches the output for your first example. It uses an analytic. I just like using them.
SQL> select * from employees;

I HAVE A SOURCE TABLE WITH 10 RECORDS AND TARGET TABLE 15 RECORDS. MY QUESTION IS USING WITH THE TABLE COMPARISON TRANSFORM .I WANT TO DELETE UNMATCHED RECORDS FROM THE TARGET TABLE ?? HOW IT IS ??

Hi Kishore,
First identify deleted records by selecting "Detect deleted rows from comparison table" feature in Table Comparison
Then Use Map Operation with Input row type as "delete" and output row type as "delete" to delete records from target table.

Delete a record from a table in a Database with Database Connectivity

I can't find the function from the Database Connectivity library that allows me to delete a record from a table of the database. I tried to use DB Tools Free Object.vi function but this one deletes only the table created with a query.
Thankyou

I have used the sql query as described above and it works fine with access DB and the DB toolkit, the free object vi only deallocated a recordset's references this will noty alter the database since the record is a copy of the databases information. The SQL delete function is very versatile and you should be able to delete records with no problem.

You can test this piece of code.
DATA:
i_tab TYPE STANDARD TABLE OF mara,
wa_tab TYPE mara.
wa_tab-matnr = '1000'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.
wa_tab-matnr = '1001'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.
wa_tab-matnr = '1002'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.
wa_tab-matnr = '1003'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.
wa_tab-matnr = '2001'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.
wa_tab-matnr = '3001'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.
wa_tab-matnr = '4010'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.
