Recover a deleted record / table

Hello,
Our Oracle DB (10.2.0.4) is on archive mode. But flashback is not enabled
In such cases, If a user deleted a table entry / a entire table itself, Is it possible to recover
How to solve this kind of a issue.
Is it really deleting from the DB or else is it just mark as flag (flag as deleted.)
regards,
Zerandib

Hello Zerandib,
depending on how the user deleted the data (DML = DELETE or DDL = TRUNCATE) from the entire table or just a table entry - you can use flashback query. Flashback query works with the undo data - so you can flashback your table until UNDO_RETENTION.
Official documentation:
http://download.oracle.com/docs/cd/E11882_01/appdev.112/e17125/adfns_flashback.htm#ADFNS01003
If the data is not stored in undo tablespace anymore - you can also use the LogMiner to rebuild your data with help of the archive logs:
http://download.oracle.com/docs/cd/E11882_01/server.112/e16536/logminer.htm#SUTIL1553
If your entire table was deleted with DDL (TRUNCATE) you need to restore your whole database and recover it.
Regards
Stefan

How can i recover my deleted records

Hello sir,
I m from j.b.diamond,surat(india). I purchased your oracle 9i (9.0.2) version since last few month. Now a days I have one problem so please solve it..
I delete few records from my database and then commit it, is it possible to recover that deleted record ? if your answer is âyesâ then, how can be it possible ? and if your answer is ânoâ then why?
Please response meâ¦â¦
Thank you.

You can recover your deleted records by using the flash back query feature available in 9i.

Recover a deleted record in NOARCHIVELOG mode?

Hello,
I'm running 10gR2 in NOARCHIVELOG mode and we do not take backups (please, let's not get into a discussion about this!).
I need to know if there is any possible way to recover a record once it has been deleted and a COMMIT has been issued? A user inserted two records in the database that they should not have, and I need to verify there is no possible way to recover those once they have been deleted.
Thank you,
Mimi

Ok so my UNDO_RETENTION parameter is set to 900...so 15 minutes after I delete the records they should not be querable using Flashback Query any longer, right?No,
UNDO_RETENTION is low threshold value of undo retention. Meaning, Oracle will try to keep at least that time before overwritten.
However, it's not gurranteed if not enough undo tablespace available, meaning it can be overwritten before the value is up if not enough undo tablespace to serve new transaction.
On the other-hand, it will not remove the undo record until it's overwritten, meaning the record could stay there for considerable amount of time if your database is not busy and undo tablespace is big.

Not sure what's the intention to make your delete irreversible,
you could actually create table newtable as select .. from old_table where <except the two records>.
Drop the old table and rename new table.
purge the recycle bin of your database

Recover a deleted recording after a save

Help!! I only realized after a save that I'd accidentally deleted the whole first half of my main narrative track. I've been working on this file for several days and was wondering if garageband saves earlier versions of a file, like word does, that can be recovered or reverted to later. Is it possible to revert to an earlier temporary file of some kind? Are aif tracks saved somewhere? If so, where?
God, I hope so!!
Thanks for your help.
Despairingly yours,
Soccergirl

Oh no!! Really?
God that's so abysmal.
I guess I always thought there must be some temporary somethingorother somewhere.
Man, how depressing.
Sigh.
Thanks for your help.

Delete records from tableA which are not in tableB

Table A contains milions of records which is the best way to delete records from tableA which are not in tableB
delete from tableA where empno not in (select empno from tableb)
or
delete from tableA where empno not exists (select empno from tableb
where b.empno=a.empno)
any help

Hi
If you can do this, do with this:
create table tableC
as select a.*
from tableA a,
(select empno from tableA
minus
select empno from tableB) b
where a.empno = b.empno;
drop table tableA;
rename table tableC to tableA;

Hi,
While doing recording check for Filter button available for the table control, if it available then do the recording for the same.
Once it is done while passing the data from internal table put the value into Filter field.
Hope it resolves your issue.

One option is to identify the table and find out the location as the number of row which should be deleted from the table and then in the bdc program instead of postioning the cursor on the row 1(using the statement perform bdc_cursor ....(01)), replace the 01 with the row number.
Second option is that if a filter control is available for the table control, then filter the data each and every time with the material number to be deleted and then delete the first row.

Deleting records from a table

Hi
I have to delete a table which is having nearly 9 crore records, I deleted some of the old records which is nearly 10-15 lakhs records and I have checked the free size of the tablespace after giving alter table <table name> deallocate unused, but the free space remains same not even 1KB is increased.
Kindly help me in this

Physically reorganizing the table is going to require having enough disk space to make a copy of the entire table. You're either going to need to find additional space on a different mount point or find things that can be dropped/deleted to free up space, at least temporarily. For example, you might drop a bunch of indexes, do the re-org, and then re-create the indexes, though this obviously makes the reorg far more risky.
Otherwise, deleting data is going to free up space in the table for future inserts although it won't free up space in the tablespace. Given that you're doing significant loads into this table, I don't see why it would make a difference whether you've got the free space in the tablespace or in the table-- either way, it's going to be used by the loads...

Procedure to delete mutiple table records with 1000 rows at a time

Hello Champs,
I am having requirement to create procedure to achive the deletes from 5 big tables. 1 master table and 4 child tables. Each table has 28 millions records. Now I have to schedule a procedure to run it on daily basis to delete approximately 500k records from each tables. But the condition is: Seperate procedures for each tables and delete only 1000 rows at a time. The plan is below. Since I am new for writing complicate procedure, I don't have much idea how to code the procedures, can some one help me to design the procedure queries. Many Thanks
1. Fetch 1000 rows from master table with where clause condition.
2. Match them with each child tables and delete the records.
3. Atlast delete those 1000 rows from master table.
4. over all commit for all 5 X 1000 records.
5. Repeat the steps 1 to 4 till no rows to fetch from master table.
Below are detailed procedure plan:----
----- Main procedure to fetch 1000 rows at a time and providing them as input to 5 different procedures to delete records, repeating same steps till no rows to fetch i.e. (i=0)-----
Create procedure fetch_record_from_master_table:
loop
i = Select column1 from mastertable where <somecondition> and rowcount <= 1000;
call procedure 1 and i rows as input;
call procedure 2 and i rows as input;
call procedure 3 and i rows as input;
call procedure 4 and i rows as input;
call procedure 5 and i rows as input;
commit;
exit when i=0
end loop;
----- Sepereate procedure's to delete records from each child tables------
Create procedure 1 with input:
delete from child_table1 where column1=input rows of master table;
Create procedure 2 with input:
delete from child_table2 where column1=input rows of master table;
Create procedure 3 with input:
delete from child_table3 where column1=input rows of master table;
Create procedure 4 with input:
delete from child_table4 where column1=input rows of master table;
--- procedure to delete records from master table atlast----
Create procedure 5 with input:
delete from Master_table where column1=input rows of master table;

Oops, but this will work, won't it?
begin

Best approach to delete records that are not in the source table anymore.

I have a situation where I need to remove records from dimensions that are not in the source data anymore. Right now we are not maintaing history, i.e. not using SCD but planning for the next release. If we did that it would be easy to figure the latest records. The load is nightly and records are updated and new added.
The approach that I am considering is to join the dimension tables the the sources on keys and delete what doesn't join. However, is there perhaps some function in OWB that would allow to do this automatically on import so it can be also in place for the future?
Thanks!

Bear in mind that deleting dimension records becomes problematic if you have facts attached to them. Just because this record is no longer in the active set doesn't mean that it wasn't used historically, and so have foreign key constraints on it in your database. IF this is the case, a short-term solution would be to add an expiry_date field to the dimension and update the load to set this value when the record disappears rather than to delete it.
And to do that, use the target dimension as a source table, outer join it to the actual source table on the natural key, and so your update will set expiry_date=nvl(expiry_date,sysdate) to set to sysdate if this record has not already been expired on all records where the outer join fails.
Further consideration: what do you do if the record is re-inserted into the source table? create a new dimension key? Or remove the expiry date?
But I will say that I am not a fan of deleting records in most circumstances. What do you do if you discover a calculation error and need to fix that and republish historical cubes? Without the historical data, you lose the ability to do things like that.

How to delete records from dynamic internal table.

Hi Experts,
Need urgent help!!!
Issue is with Dynamic internal tables.
Below is code written by me :
FORM select_query USING Lw_tabnam
                  TYPE t682i-kotabnr.
DATA : lw_line TYPE REF TO data,
          lw_line1 TYPE REF TO data.
    CREATE DATA Lw_line    TYPE (lw_TABNAM).
    ASSIGN      Lw_line->* TO   <WA_tbl>.
    CREATE DATA LW_LINE    TYPE STANDARD TABLE OF (Lw_tabnam)
                           WITH NON-UNIQUE DEFAULT KEY.
    ASSIGN      Lw_line->* TO <TBL>.
    SELECT * FROM (Lw_tabnam)
             INTO CORRESPONDING FIELDS OF TABLE <TBL>
             WHERE (t_keys).
Endform.
code is working fine.
here even the table name and where condition are dynamic,everything is fine upto this point.
Now i have to delete some record from <TBL> based on some conditons.
     for ex : ( here lc_fieldname is KUNNR)
      loop at t_kunnr.
          lw_tabix = sy-tabix.
        Read table <tbl>
                with key (lc_fieldname) = t_kunnr-kunnr ASSIGNING <wa_tbl>.
        If sy-subrc = 0.
        *Delete
        delete <tbl> from <wa_tbl>
delete <tbl> index lw_tabix.
        Endif.
     Endloop.
The above delete statement doesn't work ,even we can't use index as it gives a syntax error " something related to "index is not allowed in standard table or hash table.
Can you help me ab't how to delete records in Dynamic internal table?
Other option that i am thinking of is to create a static table of type dynamic table.
means, data itab type standard table of <tbl> .I know the syntax is wrong ,however is there any way to do this?
Thanks in advance ,
If you have any suggestion ab't this then do let me know.
bye,

Deleting records in a table based a collection

I wanna delete records in a table which do not match the records in the collection.
Since the collection is a pl/sql collection I cannot do it like
v_t v_type;
DELETE FROM sample WHERE flex_name NOT IN (SELECT * FROM TABLE(v_type(SELECT * FROM v_t)));
is there any other alternative to do the same ?

Delete records in internal table

Hi,
I have two internal tables itab1 and itab2.
I need to delete records from itab1 comparing the data from itab2. I tried to use the read statement within the main table.
My problem is itab2 and itab1 has multiple records and all the records need to be checked from itab2 with itab1 before deleting the records from itab1.
itab1 and itab2 have a common field 'runid' between them.
How can this be accomplished?
Thanks,
VG

Venkat, inside a loop a IF SY-SUBRC NE 0 doesn't make sense because you are in the loop only after the condition in WHERE clause is satisfied (which means SY-SUBRC is always 0). Also you are missing another ENDLOOP.
