  Hello

  There is really little detail, but if you work on eBS I suspect you're pointing the synonymous or something similar.

• Using 'STORAGE of REUSE' with the command 'TRUNCATE TABLE '.

  Because ' truncate table... reuse storage "speed up the tronquantes process?
  
  Sometimes statements truncation takes about 30 minutes and other times just a few minutes.
  
  What are the backs of uinsg print 'reuse storage?

  The RE-USE of STORAGE clause is used to prevent the allocated storage of back to the pool.
  Consider this scenario for a typical daily load of an intermediate table

  1. Empty the table of yesterday's data - TRUNCATE it
  2. Load the table with today's data - INSERT 
  

  If you load a large number of records it takes time for Oracle to allocate storage for records
  When you use Oracle TRUNCATED must return the storage allocated to the pool.
  Then when you INSERT new records, that oracle has to allocate the space that he could have used, but returned to the pool.

  If you use TRUNCATE... RE-USE of STORAGE Oracle truncates the table but keep the storage and it will reuse the same storage
  When you do the INSERT instead of having to take the time to allocate new storage.

  So, there are two options to speed up ETL processes like that.
  1. use TRUNCATED... RE-USE of STORAGE and a standard INSERT query

  2. use TRUNCATE and INSERT / * + APPEND * / and make the table NOLOGGING to INSERT it. This will make a big
  load. Oracle must allocate space, but the load mass will make them more effective than a standard INSERT.

  -editing to update after reading the reference asktom
  Storage of back to the pool takes time, so REUSE STORAGE of coding may be faster. The real advantage comes with the next load of data, however if you use a standard INSERT (and not in BULK or direct load) because Oracle failed to reallocate storage.

  If RE-USE eliminates the return of storage to the pool, as well as the allocation of the new storage for the next INSERTION.

• Grant to truncate table

  I truncate tables 4 to another user.
  
  I grant kind of what I need to to my user to perform this specific task in the table in another schema?
  
  Thank you
  Luciana

  The only way to be able to issue a command TRUNCATED on a table, you aren't owner would be to give the DROP ANY TABLE privilege. No worthy of their name DBA would allow that to happen.

  Another solution would be to create a stored procedure, owned by the owner of the tables (or a DBA account) who performs the dynamic SQL statements to truncate the tables in question. The owner of this procedure would then grant you EXECUTE access to the procedure.

• Interruption of TRUNCATE TABLE command

  Hello
  
  I made very dangerous mistake today: TRUNCATE TABLE on the production database. :-(
  
  But in a few seconds (2 or 3), I managed to break the operation (before the end of the run).
  It was quite a large table, now (after the accident), there is more records then 32 million.
  
  We need to know, are all deleted records?
  
  We have no proper backup, to compare the records with her.
  And I couldn't find any detailed description of the works to TRUNCATE.
  
  Can you please:
  1. say, on any method to check if there are deleted records?
  2. relationship to any resource, where I can read in detail, on the operation of TRUNCATE TABLE .
  
  Thank you, in advance, to help

  I know that the table TRUNCATE TABLE statement is atomic. It fails or succeeds. Don't truncate all the lines or none at all. So if you interrupt a statement TRUNCATE TABLE your table must remain in its original state.

  This can be illustrated below:

  SQL > CREATE TABLE TEST AS SELECT * FROM ALL_OBJECTS;
  
  Table created.
  
  SQL > INSERT INTO TEST SELECT * FROM TEST;
  
  12421 rows created.

  HTH!

• Truncate Table generates cancel?

  What I understand, TRUNCATE TABLE resets the high water and after some discussions and information on the web creates a small amount of cancellation. For example, http://www.orafaq.com. However, documentation of Oracle 11 g 2 to truncating Tables and Clusters makes clear that it does not generate just undo.

  Quote: A TRUNCATE statement does not generate the cancellation information and committed immediately. It is a DDL statement and cannot be cancelled.

  TRUNCATE is apparently done a COMMIT before and after he runs, which would explain why there is no ROLLBACK. And if I'm not mistaken, any DML or DDL statement must create an entry in the log again first, before you run.

  Which is correct? Does TRUNCATE really create no CANCELLATION and implicit VALIDATION is perhaps only a protection measure, or what is the real story here? I tried a few tests, playing with the employee_demo table, but I have not been able so far to know what has changed in the UNDO tablespace. Unfortunately, I'm not a great expert on PL/SQL and do not use it much. Is there a way to simply to query or compare the cancellation of table before and after a truncate table operation to see the difference? By comparing the size is not.

  Thank you!

  Summary/Conclusion:

  The answer, in other words, is that TRUNCATE TABLE Undo. This cancellation information cannot be used by the user to RESTORE a TRUNCATE TABLE, which also applies to the other DDL statements, but may be required by the body to perform the database crash recovery.

  Because TRUNCATE TABLE changes the metadata in the data dictionary and resets the high tide of the object, it produces much less that cancel the DML statements as DELETE. However, it would probably not be the Oracle database if everything were that easy.

  If you happen to find this interesting question and wish to know more on it again and cancel the process regarding the DDL statements, some of the responses I received the case very resourceful and provided information you many not know or will not find in the usual documentation.

  I can mark only one answer is right and just caught the first response that provided an answer to my original question. The answers that I've marked as useful are those replies which I think has provided good explanations or added interesting new aspects or information thereon.

  Thank you all for your time and your contributions!

  To check the generation of cancellation (example):

  SQL > select count (*) from t1;

  COUNT (*)

  ----------

  1000000

  1 selected line.

  SQL > select name, value of V$ mystat ms, v$ statname sn where sn.statistic # ms.statistic # and sn.name like '% cancellation' and ms.value =! = 0 ;

  NAME                                                                  VALUE

  ---------------------------------------------------------------- ----------

  cancel changes vector size 192

  1 selected line.

  SQL > truncate table t1;

  Table truncated.

  SQL > select name, value of V$ mystat ms, v$ statname sn where sn.statistic # ms.statistic # and sn.name like '% cancellation' and ms.value =! = 0 ;

  NAME                                                                  VALUE

  ---------------------------------------------------------------- ----------

  cancel the change in size of vector 31272

  1 selected line.

  The cancellation that would have been generated by a deletion would have been of the order of one hundred twenty megabytes - but you'll have to take my word for it.

  This small amount of cancellation would have been associated a few blocks management cleared space, the day and possibly put segment header some updating of the data dictionary (your changes of $ tab_stats).

  To prove that some cancel the blocks of space for the table (and its indexes) management, you would probably have to spend just before truncation, then truncation of log files, then empty the current log file to get a picture of minimum log that you could review to see which blocks had been affected by again them and the bits from the redo had correspondent (or on the contrary (, reversing) entries created in cancel it. You would then be able to see exactly what had happened to the table (and index) blocks and how this action had been protected by the cancellation.

  Bottom line - people often say that "truncate" generates no cancellation, what they really mean is that it generates no cancellation for data, although it always generates a relatively small amount of cancellation for the meta-data.

  P.S. before everybody does point out that there are always special cases - truncation of a table in a cluster is implemented as a deletion.

• Truncate table audit

  11.2.0.4.0

  Possible to truncate table of audit?  Ive tried some of the methods that are being pushed on the web, but nothing works.

  -clear the aud$

  truncate table sys.aud$

  create the table t1_trunc as

  (select * from dba_objects)

  Audit truncated;

  table of audit;

  truncate table t1_trunc;

  Select * from sys.aud$ not = no line.

  user47708, I don't think that you should open a SR because I can audit truncated.  First sysdba users are given unverified as regular users, then you need to perform the truncation of a new session started after the audit truncate was issued.  I have both audit and audit table truncate together.  The database must have naturally the audit_trail one value other than 'none '.

  - -

  > audit truncated;

  Verification succeeded.

  > table of audit;

  Verification succeeded.

  > connect mpowel01
  Enter the password:

  MPOWEL01 > truncate table marktest.

• The truncated table rows

  Hi team,

  One of my colleague ran a batch which will truncate a table and insert the final table by extracting data from different tables in backup taking the old table.

  But today before 10 minutes he missed to keep the export backup of this table and ran the batch. All the old data of the truncated table and now we need these data.

  Flashback is DISABLED in our case and Undo retention is dry 7200 and since it is a DDL so it will change the definition of the table.

  Is it possible to get the data that truncated.

  Daily HT full backup will run and we are in the process of restoring the backup but the db size is 4 TB and it will take time and then let's apply archive logs, before that got truncated.

  Until can we try something else?

  Hemant seems good to me.

  Please check the Version of Oracle where you are restoring the database and the Oracle version of the primary database that saves youi have taken.

  I'm 100% sure that there could be the difference in the release.

  We faced this problem 2 times and every time the issue is different binary or different architecture was the problem.

  could someone help, please?

  
  Another question: can I continue the ETL when it fails? without starting from the beginning?

  Hi Mate,

  Simply delete the duplicate value, it is not a problem

  Finally give the validation in your PB, make waiting in line and raise your execution plan...

  I'm sure that this task is now complete.

  It will be a great help on your side, if you share did you read me the article. and give me the number?

  I am also looking for a validation script now.

  Thank you

• I want to know when we issue statement truncate table in oracle.

  I want to know when we issue statement truncate table in oracle. No newspaper will be write in the redo log. But we can recover data using flashback or SNA.

  You have received the reply above. Archive of flashback stores data.

  See the link provided above to CREATE an ARCHIVE of FLASHBACK in the doc of SQL language

  Specify the table space where the data archived for this flashback data archive referring to be stored. You can specify that a tablespace with this clause. However, you can then add tablespaces to archive flashback with a statement ALTER FLASHBACK ARCHIVE database.

  The data is moved to storage of archives and restored from there when you query for archive flashback.

• Truncate table removes the corresponding LOB segment of the table or not?

  Hi all
  
  I have little table with BUSINESS segments, if I pull the table truncated on the table it will purge the LOB segment as well?

  It will not erase the LOB segments, but it must release the majority of the allocated space.

  2. If you want to recover the space, we need to run the command, below is correct?

  ALTER TABLE CHANGE LOB (LOB_COLUMN) (SHRINK SPACE);

• Truncate table issues

  Hi people,
  
  Environment: 10g Rel 2
  
  I am trying to prove the following two points by way of experimentation
  
  truncate table operation, her will reset the high water mark (HWM) on the first block of data for use in the segment of the table
  
  # Take a snapshot of HWM before the truncation operation
  

  select a.BLOCKS - b.EMPTY_BLOCKS -1 HWM
  from
    (SELECT BLOCKS
     FROM   DBA_SEGMENTS
     WHERE  OWNER=UPPER('JIM') AND SEGMENT_NAME = UPPER('EMPLOYEES')) a,
     (SELECT EMPTY_BLOCKS
      FROM   DBA_TABLES
      WHERE  OWNER=UPPER('JIM') AND TABLE_NAME = UPPER('EMPLOYEES')) b;

  Released: 7
  
  truncate table JIM. EMPLOYEES;
  
  Re ran the code above and got the same result (i.e. 7 blocks). I expect to see 0 instead blocks? The query above is the correct method of
  find the HWM?
  
  
  
  b, the truncate operation also truncates the corresponding indices of the table
  
  Q, is there a view that will show you all the values of indexes on the table? These values will probably be meaningless, but I would like to see them before
  and after the truncation operation.
  
  Thank you

  (a) If you would read on the empty_blocks column in dba_tables, you would have known that it is populated with dbms_stats.
  Did you run dbms_stats.analyze_table?

  (b)
  Didn't this view.
  All the dictionary views are documented in the DICT view and documentation online.

  I get the error "PLS-00103: encountered the symbol EXECUTE when expecting one of the following values: interface.
  
  Could someone help me please?
  I thank very you much in advance!

  DDL statements are to be executed using execute immediate PL/SQL code, for example

  ..
  ..
  EXECUTE IMMEDIATE 'TRUNCATE TABLE fred';
  ..
  ..
  

  Only SQL (DML statements) can be incorporated directly into the PL/SQL code.

• truncate table another user via trigger?

  Oracle 10.2.0.4
  
  A user USER1 should be able to truncate a table of another user, user 2.
  
  I will not give drop any table, there are a lot of patterns in this PB. It must be transparent, because it happens from an application, so I can't substitute a procedure:
  
  exec ('table_name') drop_user2_table;
  
  but USER1 executes: truncate table table_name;
  
  
  Is there an any place of relaxation for this command?.

  You thought you found the solution. If so, please indicate the post as answer and correct.

• Truncate table use in the procedure...

  Dear,
  
  I created the test table.
  
  Now, I have written a procedure like this.
  
  create or replace procedure trunc_test
  (ov_v_output OUT VARCHAR2) IS
  Start
  truncate table stable.
  end;
  
  I got error message like
  
  PLS-00103: encountered the symbol "TABLE" when the expected in the following way:
  
  := . ( @ % ;
  
  Someone help with this...
  
  Thank you and best regards,
  Raja.

  TRUNCATE is a DDL statement, so you cannot use it directly in PL/SQL. You must run dynimically using EXECUTE IMMEDIATE.

  So, your code should be

  create or replace procedure trunc_test (ov_v_output OUT VARCHAR2)
  is
  begin
   execute immediate 'truncate table testing';
   ov_v_output := 'Success';
  end;
