How to delete an entry in a table when drop a user????

I want to write a trigger that when someone drop a user, delete the related data in one table ..
how to write this one ???

Hi,
You can create a DDL trigger. (a trigger that fire after a DROP command for example):
http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_7004.htm#i2235611
In this trigger you can look for a specific event (use the ora_sysevent, ora_dict_obj_owner, ora_dict_obj_name system variables if you only wnat to track the drop of users.
you have a such example here:
http://psoug.org/reference/ddl_trigger.html
I suggest you to start with a trigger that log all drop command and then you issue different drop command and see how the trigger is logging the different events ..

How to delete the entries in CDCLS table

Hi All,
There is a potential issue with the size of table CDCLS on production system. We need to reduce or manage the amount of data in this table. CDCLS is a cluster table and cannot be reduced directly,
So first we were reduced the entries in CDHDR and then from CDPOS tables.
After that we tried to reduce the entries from CDCLS table through the program - RSSCD7RE, We are facing the error as - no data available and No active archive key was selected.
Please help me out, how to proceed further in this task. Thanks in advance.

Go to DB15 and see the archiving object.
You can also use the archiving object CHANGEDOCU, please refer SAP documents for that.

How to delete the entries from NAST table

Hi,
Please help me out by providing any function module that delete's the entries from hte NAST table.
Regards,
Kiran.L

REPORT ZSCD_TEST13.
delete from nast where VSTAT = '1'.
=====
If you see the FM : NAST_DELETE_OBJECT, its only useful when NACHA = 7 (i.e. message transmission medium = Simple Mail)
For others its not useful.
We had similar issue few days back and after long RnD, we straightaway deleted the entries using the Zprogram.

How to delete obsolete entries in SID table

I have an Infoobject (0PCA_ITEMNO) without master data and is used in a DSO. The sid table of the info object and its index has grown very large to about 207 gB. The DSO is periodically selectively deleted to hold the last 3 months data. How can I delete the the old and unused sid table entries to reduce the size.

Correct...you wouldn't want to delete the SID table values using custom code. This would potentially cause inconsistencies because you may inadvertently delete a SID value that is located elsewhere in your environment.
For example, if you have an InfoObject with SID value 1 for actual value of A1 and it's deleted. However, there is an InfoCube that has SID value 1 for this InfoObject in a dimension table.
To remove the values from the SID table for this InfoObject, your best bet is to use RSRV as stated before.

BPM question - Delete all entries in a table and Insert data

Hello,
I'm new to PI BPM and have this scenario to implement.
I'm supposed to delete all entries in a table and then insert data to the same table.
Is BPM necessary? If it is, what is the best practice to implement my scenario?
I want to make sure that all entries were successfully deleted before insert data.
How do I check if all entries in the table were deleted successfully before
initiating insert.
Thank you.
-Won

Hi Won,
Yes, this is possible without BPM.
You have to create 2 separate mappings, each for deleting & inserting the records.
You will have 2 different Interface mappings as well.
But in ID, create a single interface determination.
In that, configure Deletion interface mapping first and in the second row, configure Insertion interface mapping.
Please make sure that the parameter 'Mainain Order At runtime' is checked in interface determination.

How to find latest entry in the table according to time

how to find latest entry in the table according to the time
is there any function module to do so
\[removed by moderator\]
Regards
Shashi
Edited by: Jan Stallkamp on Aug 25, 2008 4:39 PM

Hi,
If you want to read the entry from an internal table,
sort the internal table in the descending order by the time and
delete adjacent duplicates by comparing the fields other than time and the internal table will have the latest record.
Suggestion: instead of only time try to have one more field called date with the time combination

    MODIFY itab.

How to delete forecast entries with zero current and original qty from a particular forecast set which span across multiple forecasts

how to delete forecast entries with zero current and original qty from a particular forecast set which span across multiple forecasts

Hi,
There is no way to delete those records selectively from front end.
The best possible way is to delete the records from MRP_FORECAST_DATES tables from backend.
Hope that helps!!

How to delete the data from partition table

Hi all,
Am very new to partition concepts in oracle..
here my question is how to delete the data from partition table.
is the below query will work ?
delete from table1 partition (P_2008_1212)
we have define range partition ...
or help me how to delete the data from partition table.
Thanks
Sree

874823 wrote:
delete from table1 partition (P_2008_1212)This approach is wrong - as Andre pointed, this is not how partition tables should be used.
Oracle supports different structures for data and indexes. A table can be a hash table or index organised table. It can have B+tree index. It can have bitmap indexes. It can be partitioned. Etc.
How the table implements its structure is a physical design consideration.
Application code should only deal with the logical data structure. How that data structure is physically implemented has no bearing on application. Does your application need to know what the indexes are and the names of the indexes,in order to use a table? Obviously not. So why then does your application need to know that the table is partitioned?
When your application code starts referring directly to physical partitions, it needs to know HOW the table is partitioned. It needs to know WHAT partitions to use. It needs to know the names of the partitions. Etc.
And why? All this means is increased complexity in application code as this code now needs to know and understand the physical data structure. This app code is now more complex, has more moving parts, will have more bugs, and will be more complex to maintain.
Oracle can take an app SQL and it can determine (based on the predicates of the SQL), which partitions to use and not use for executing that SQL. All done totally transparently. The app does not need to know that the table is even partitioned.
This is a crucial concept to understand and get right.

Hi Naren,
First get the index number of the IT_data table and store it in one variable whose declaration like this.
data: tabix type sy-tabix.
while reading the internal table it_data set the tabix variable.
tabix = sy-tabix.
Instead of the above use below one.
Delete it_data-objek
Use the Below statement it will delete the row from the internal table.
Delete it_data-objek index tabix
Thanks,
Chidanand
