Deleting rows by key from several tables

Hello!
One of action of my stored procedure is deleting rows from several tables on a key , that I'm getting through statement :
delete from table3 where key_column in ();
delete from table4 where key_column in ();
commit;
select key_column from Table!
minus
select key_column from Table2
Unfortunately the number of lines mentioned by this statement isn't known in advance .
How do You think , is better way to
-- execute select each time for every delete-statement or
-- create table as select result set and then select again keys for each delete- ststement or
I'm usung 11.2.0.3
Thanks and regards,
Pavel

By using : 1.trigger 2. on delete cascade you can achieve this.

Adding or Deleting Rows and Columns from Tables

I have notices that you can't delete or add a row or columns from a table in iWeb without having problems.
You may get two added or deleted.
I should indicate that the table comes from Excel.
Does anyone know of a work-around?

Problem 1 - The sub-form 'Stds' was not configured for repeating rows.
Problem 2 - The script was on the wrong event. The script should be on the 'change' event and not the 'initialize' event.
Problem 3 - Which header row in which sub-form are you referring too?

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...

Since the last update yesterday to firefox 4.0.1 my program "asus security protect manager" doesn't work properly. That means, that the saved keys from several websites not remembered for lock in.

since the last update yesterday to firefox 4.0.1 my program “asus security protect manager” doesn’t work properly. That means, that the saved keys from several websites not remembered for lock in.

Sorry you are having problems. First of all try Fifrefox's safemode.
*[[Troubleshoot Firefox issues using Safe Mode]]
If that works post back for further advice.
Next step, if safe mode did not work.
First: Try a clean install, (you have had a none standard version installed previously) that involves deleting the program files. Then if necessary try troubleshooting by creating and using a clean empty Firefox profile.
See
* this recent post [/questions/940399#answer-377134]
* http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Clean_reinstall
Second: try a New Profile
*http://kb.mozillazine.org/Profile_Manager#Creating_a_new_profile
* this will be an additional profile, it is still worth backing up any existing or currently working profile on a regular basis
**[[Back up and restore information in Firefox profiles]]
* Until you are absolutely confident about the repercussions I suggest
** always use an empty folder when creating a new profile
** never delete or rename profiles, just disable or remove shortcuts
** after creating a new test profile open it and check for any addons or plugins that may be have been included by default

How to speed up the deletion of 11million records from the table

Hi,
How to speed up the deletion of 11million records from the table.
I need expiditious reply. Please do the needfull in advising
Regards

Please try to understand the question.Well it would help if you would answer some of the questions you have been asked as your question is not complete and clear and no matter how hard we try, we really need you to try and ask the question properly.
So as previously asked
Which simply supports the idea that we need:
1) better definition of the business purpose (why)
2) oracle version
3) operating system
4) hardware configuration
to give a moderately accurate answer.
I would like to add
5) How many rows in total in the table to begin with.
6) What is your delete statement
7) Is this a one time operation or will it happen regularly
8) Can you use partitioning.

Remove partition key from partitoned table

can somebody help me with a sql syntax to remove a partition key from a partiton table . The scenario is explained as follows:
create table t1 (c1 number, c2 number ,c3 number)
partition by range (c1, c2)
(partition p1 values less than 11,
partition p1 values less than 21,
partition p1 values less than 31 );
i have data in this table and lot of indexes built, so i cannot drop this table to recreate it.
All i want is to remove c1 from partition key (c1,c2).
I will appreciate if somebody can give me a SQL syntax for this.
Ajay Nerumati.

Have you used the debugger and checked that the selectedRowKey is filled?
Can you elaborate what you mean by {qoute} ...does not work ...>
Do you have a reason not to use the current selection listener selectionListener="#{bindings.NotificationOfDifficultiesVO.collectionModel.makeCurrent}" on your table to let the framework do the work for you and then simply call the delete method on the VO?

Physical deletion of WBS elements from PRPS table

Hi Experts,
In CJ20N transaction:
When I delete a project with project profile (ZABC), the following actions are performed:
- The project entry are physically deleted from 'PROJ' table.
- The WBS entries are physically deleted from 'PRPS' table.
When I delete another with with project profile (ZXYZ), the following actions are perfomed:
- The project entry are physically deleted from 'PROJ' table.
- The WBS entries are NOT physically deleted from 'PRPS' table.
What is the reason for not deleting entries physically from PRPS table?
Thank you for your valuable answers.

Hi Experts,
In CJ20N transaction:
When I delete a project with project profile (ZABC):
- The project record is completely deleted from 'PROJ' table.
- The WBS records are completely deleted from 'PRPS' table.
When I delete another project with different project profile (ZXYZ):
- The project record is completely deleted from 'PROJ' table.
- The WBS records are NOT deleted from 'PRPS' table.
What is the reason for not deleting records from PRPS table for another project (Project profile: ZXYZ)?
Thanks in advance for your valuable answers.

Select from several tables

i have 3 tables in my database..
table1 with one column
table1
table1_id
11
12
13
14
table2 with one column
table2
table2_id
21
22
23
24
table 3 with 2 primary foreign keys from table1 and table2
table3
table1_id table2_id
11 21
11 22
12 23
12 24
13 21
14 22
i want a select statement that selects all from table2 where the specified table1_id is not in the list of the table1_id in table3
for example if i want the list for id 11 it should return (23, 24)
i came up with the following but it didn't work
select table2_id
from tabel3 c, table2 b
where table1_id <> 11 and c.table2_id = b.table2_id
i know my explanation is not that clear..
but any effort will be appreciated

This should do it. I didn't create the tables, so untested.
SELECT t3.table2_id
FROM table_2 t2
 INNER JOIN table3 t3
 ON t2.table2_id = t3.table2_id
MINUS
SELECT t3.table2_id
FROM table_1 t1
 INNER JOIN table3 t3
 ON t1.table1_id = t3.table1_id
