Protect table againts deletes & truncates

Hi
I need to protect a table in my schema againts the DDl commands DELETE & TRUNCATE ? is this can be done via triggers ???
please share your idea's
thanks in advance
regards
raj

you can use trigger but not to avoid DML statement delete. you can use trigger to see affected row values before or after the event.
The trigger can be invoked once, when some event occurs, or many times, once for each row affected by an INSERT, UPDATE, or DELETE statement. The trigger can be invoked before or after the event.

Release of space after delete/truncate table

Hello,
How does release of space after delete/truncate table works? Is the space used before deletion released once delete is complete or not? Will I see the space occupied by deleted table as free in dba_segments or will I need to reorganize the table (drop and recreate again?). Reason why I am asking is that I can see table with 0 rows, but in dba_segment I can see it is occupying few gigabytes....
Thank you

Here is a little illustration for you;
SQL> conn ogan/password
Connected.
SQL> create table ogan_deneme as select * from all_objects;
Table created.
SQL> select count(*) from ogan_deneme;
COUNT(*)
    228470
SQL> set line 1000
SQL> set pagesize 1000
SQL> select * from dba_segments where owner='OGAN';

Different between drop,delete,truncate.

hi.
kindly what is the different between drop table,delete table,truncate table.
thanke you all .

Hi
Drop is a ddl statement which removes the existence of the table along with the data.
Delete is a dml statement which removes only the data from the table.
Truncate is a ddl statement which removes only the data from the table.
1) You can specify condition in delete statement which would remove only the specific data from the table. You cannot specify condition in truncate statement so all the data would be remove.
2) Delete keeps the records in buffers/undo segment so that you can rollback. Whereas truncate does not so you cannot rollback, moreover implicit commit is done on issuing of truncate
3) Truncate also resets high water mark of the table whereas delete does not.

Tables are deleted but database size does not change in sql server 2008r2

Hi All,
20GB Tables are deleted in my database but database size does not change and disk size showing same size.

Hi ,
I have ran the Disk usage by Top Tables report and Identified couple of tables with unwanted data for last 5 years. I have deleted the data for the first 3 years and then ran the Disk usage by Top Tables report again. When I compared the report before
and after the data deletion, I have noticed certain facts which is not matching with what I know or learned from experts like you. The following are the points where I am looking for clarification:
1.Reserved (KB) has been reduced. I was expecting the data Reserved (KB) will remain the same after the data deletion.
2. The Data(KB) and Indexes(KB) fields have been reduced as expected. The Unused(KB) field have been increased as expected.
I was expecting the total of Data(KB) and Indexes(KB) field space gained will be equal to the Unused(KB) field gained after deleting the data. But that is not the case. When I deducted(subtracted) the difference in the Reserved(KB)(Difference before
and after data deletion) field from the Total of space gained from the data deletion is equal to the Unused(KB) gained field value.
I am not a SQL expert and not questioning but trying to understand whether we really gain space by deleting data from the tables. Also keen to get the concepts right, but my testing by deleting some records confused me.
Looking ahead to all your expert advice.
Thanks,
Vennayat

Shrink Oracle Table after Deletion

A few database tables are very big. An Oracle table still holds the disk space occupied by deleted records according to http://stackoverflow.com/questions/6540546/oracle-10g-table-size-after-deletion-of-multiple-rows. Re: shrink table after delete teaches the following commands to release the idle space from the table.
ALTER TABLE TABLE1 DEALLOCATE UNUSED;
ALTER TABLE TABLE1 ENABLE ROW MOVEMENT;
ALTER TABLE TABLE1 SHRINK SPACE;
ALTER TABLE TABLE1 MOVE;
1. Are the commands feasible?
2. Are they safe?
3. What will be the impacts of running the commands?
4. Is there any other workable safe approach shrinking a table?

Hi,
I advise using shrink table operation.
The tablespace which belong to your table must be in ASSM (Automatic segment space management) to use shrink.
Shrink is safe but you need to run two commands :
1)ALTER TABLE TABLE1 SHRINK SPACE COMPACT; (This is long operation which moves data, but can be done online)
2)ALTER TABLE TABLE1 SHRINK SPACE; (this is quick if you run SHRINK SPACE COMPACT before, it only shift the High Water Mark. Be carreful if you don't run SHRINK SPACE COMPACT before your table will be locked for a long time)
Another point, is that execution plans are calculed using the HWM so SHRINK the table (The 2nd command) will invalidate all the cursors in shared pool where the table is in. So execution plan need to be recalculated (often not a problem).

Table entries deleted in Customized table.

Respected Guru's
table entries in a customized table were deleted in production system, no transports pertaining it was found.
Table entries were updated using bapi.
Please help me to know how the table entries were deleted.
Daya.

Hi Johnson,
you might have to restore the DB Backup for the table to gt back the data....
Furthermore, if you want to track how the entried were deleted then there are 2 ways to go about it:
If the Deletion of the records was through an application (FM,Program call) then there should be Chande Documents available for them and you can search them by hitting tables CDHDR and CDPOS...
If the Deletion of the records was done physically the you can try looking into the tables UASE16N_CD_KEY and UASE16N_CD_DATA (deletion from transaction UASE16N) or tables SE16N_CD_KEY and SE16N_CD_DATA(Deletion from SE16). This will give change pointer documents if the records were deleted using these transactions...
Another option might be that somebody has used the Database utility and selected the option Delete Data. In this case you can have a look at the object log....
Hope this helps....

Sitakant.

Pasting content into table cell deletes existing content. Why?

Pasting content into table cell deletes existing content. Why?

I'm not sure why you would expect something different. If you put something into a cell, then that is the contents of the cell. If you want to preserve the existing contents when pasting additional content, you don't want to paste into the cell, you want to paste into its contents.
Select the cell, then click again to put the insertion point into the contents, then Paste.

Count total number of record of table with deletion from archiving object

Does anyone know is there any SAP standard program to count the total number of record of the table with deletion from Archiving Object and display in repprt?

Not sure of the question. Are you looking to get the sql "select count(*) from table" from using the TopLink expression framework or are you getting that SQL already and want something else?
If you are looking just to get the count from a table/class, you can use a ReportQuery:
ReportQuery rquery = new ReportQuery(ClassToQueryOn.class);
rquery.addCount(); //equivalent to count(*);
session.executeQuery(rquery);
You can use a report query to return data instead of objects, and use selection criteria just like a normal read query.

Global Temporary Table not deleting Rows

why is my Global temp table not deleting the rows after commit see below,
CREATE GLOBAL TEMPORARY T_CHG
TBE VARCHAR2(7),
ABC VARCHAR2(8),
EFDA VARCHAR2(6),
ABD VARCHAR2(9),
A_ID VARCHAR2(128),
C_DATE,
ON COMMIT DELETE ROWS;

Quite a few syntax issues with your create statement. It would have helped if you had posted a SQL*Plus session showing your results. Here is mine which works just fine:
sql>create global temporary table t_chg
2 (
3 tbe varchar2(7),
4 abc varchar2(8),
5 efda varchar2(6),
6 abd varchar2(9),
7 a_id varchar2(128),
8 c_date date
9 )
10 on commit delete rows;
Table created.
sql>insert into t_chg values ('1', '2', '3', '4', '5', sysdate);
1 row created.
sql>select count(*) from t_chg;
COUNT(*)
1
1 row selected.
sql>commit;
Commit complete.
sql>select count(*) from t_chg;
COUNT(*)
0
1 row selected.
