• Do UPDATE statement in line for coherent reading?

  Hi all
  I have a question for the update statement, do UPDATE statement 17Etat for coherent reading? As a statement of pure update: update t set col1 = col1 * 20;
  
  I'll check with the following steps:
  ######################################
  Preparation: Tables Create1:
  ######################################
  t_update_old (col1 int, col2, col3 float int primary key (2000));
  
  ######################################
  Preparations: generate data for two tables:
  ######################################
  insert into t_update_old
  Select seq_1.nextval, seq_1.nextval, chr (seq_1.nextval) of double;
  for x in 1.17 loop
  insert into t_update_old
  Select seq_1.nextval, seq_1.nextval, chr (seq_1.nextval) of t_update_old;
  end loop;
  
  
  ######################################
  Description of the run
  ######################################
  Create 2 sessions: S1 & S2
  Session S1 updates t_update_old using the following statement:
  Update t_update_old set col2 = col2 * 20;
  
  S2 session will update t_update_old for a specific line.
  Update t_update_old set col2 is + 1 col2 where col1 = 100000;.
  
  The two session are performed in the following order:
  1 point in time: S1 began.
  Point in time 2: S2 started.
  Point in time 3: Action update the 100000th ranks in t_update_old by S2 is finished, validation of the transaction in S2 and S2 is finished.
  Point of time 4: update t_update_old of S1 with the 100000th line in t_update_old.
  Point 5 of time: S1 is finished.
  
  ######################################
  The Question is:
  ######################################
  What is the result of the following statement:
  Select col2 where col1 = 100000;
  
  100 000 * 20 = 2 000 000
  or
  (100 000 + 1) * 20 = 2 000 020

  By default in Oracle, each SQL statement see data if it exists when begins the execution of SQL statements and the READ COMMITTED isolation level, the effects of each committed transaction are taken into account by statements that start other transactions or validated. The answer is therefore 2 because I understand that the transaction in S2 is committed before start of query in S1.

  Things get complicated if query in S1 starts before request for S2.

  Hi Mariam,

  It seems that your ID Adobe was initially registered in Pakistan due to which it is not allowing you to make purchases in the United States.

  You can create a new Adobe ID, register in the United States and then it should allow you to make a purchase.

  Let us know if it works or not.

• How to get a update statement faster?

  Hello together,
  
  I have an update statement on a view in line composed of two tables A and B.
  
  He works and updates the table column has a value of the corresponding entry in the table B.
  
  This 1,800,000 update records in table A are updated.
  
  The table, there are a few clues.
  
  If I drop the update indexes is much faster (instead of 2,5 hours, that just 0.5 hour).
  But the time needed to re-create the index is much more that I saved thanks to the removal of the index. (4 hours!)
  
  So I do not remove the indexes and perform the update.
  
  My update statement runs in mode RBO a uses the FULL (A) - tip to prevent oracle to use the index when you create the inline view (connecting A and B).
  
  It made a difference for the execution of the update statement if it runs in either CBO or RBO mode?
  
  What can I do to get faster update statement?
  
  Thank you very much in advance for any help.

• Internal mechanism behind a "update statement"

  Suppose that I published an update statement to change the value of "salary" columns in a table, I does not issue of "committing" again, now when I select the column in my own session, I am able to see the new value, but other users in different sessions can not see the new value for them, I understand that old data is read in the undo tablespace , but for me, the new value source, please explain in detail the inside what is happening behind it.
  
  Thanks in advance.

  Think of it this way:

  No matter who's going to read a block will recover from the buffer cache (if is not in the cache, it must be read from the disk, but you will get it back in the end of the cache).

  Now, the rules of consistency Oracle reading means that you can 'see' data that is compatible with the point in time that you are interested in (the snapshot SCN). If the data that you read from the buffer cache are 'too new', then your session automatically restores data in the block, by referencing the undo data. This is known as a coherent mode get, as the buffer is recovered pursuant to a specific point in time, or SNA.

  Now, in the case of non-validated data, the transaction is marked as active, so, others Restore automatically, using undo, the previous version of the block. If the session that made the update and still holds the lock (i.e. data only has not yet been validated), Oracle can see that the transaction is the property of the current session and will not restore the data and returns the current data in the data block.

• What update statement is sent to the database?

  In several pages, I use the Apex line (DML) 4.2 automatic treatment processes. If I do an update of a record, which are columns in the update statement? All columns, only the displayed, only the columns changed, also the PK column?

  As far as I can see now all the columns that are displayed are updated, also the PK, which is display only.

  I ask this, because when the PK is updated (not changed is screen only) all tables in my 75 cases, where this PK is used as FK, will get a lock.

  I did some tests and find out that indeed the Apex is updating all the columns used in the elements by Type of Source is the database column. Even if this item is display only, read-only, etc.!

  My solution now, to prevent the locks, is the following:

  Automated line Fetch:

  Primary key column value containing point: Pxx_ID

  ID of the primary key column: (this is the primary key)

  Pxx_ID (display only, hidden or read-only)

  Source: only when the current value in session state is set to zero

  Source type: static assignment<-->

  Source of value or expression:

  Treatment of automatic line (DML)

  Primary key column value containing point: Pxx_ID

  Primary key column: ID

• GoldenGate reproducing not UPDATE statement

  Hi all

  I have this problem with my process of goldengate. I created processes extract and replicat process, I was loading initial thru expdp and impdp. All right (insert, delete) until execution of the update statement. He added my replicat process.

  Here is the error:

  2013-07-22 17:05:16 WARNING OGG-01431 abandoned grouped transaction on "OWNER. Table_name', mapping error.

  2013-07-22 17:05:16 WARNING OGG-01003 repositioning of rba in seqno 162688 0.

  2013-07-22 17:05:16 WARNING OGG-01003 repositioning of rba in seqno 162688 0.

  The table does not have the keys to the identifier.

  How should I solve my problem?

  Thank you very much in advance for gurus.

  When you get a mapping error, there will be more details on the issue in the discard file. Take a look here for the error.

  But in general, updates, you must make sure that you did a TRANDATA ADD on the side of the source in order to have the columns, you must apply the operation target and on target, if you do not have a PK or the user interface, you must specify KEYCOLS in the card then Replicat knows which columns to use to format the WHERE clause.

  Let us know what error is in your file throw, and we can go from there.

• Error in update statement

  Hello
  
  I wrote an update statement as below:
  
  Update (select a.col1, a.col2 from table1, table2 b
  where a.pk1 = b.pk1 and
  a.PK2 = b.pk2 and
  a.PK3 = b.pk3 and
  a.PK4 in)
  Select a.pk4 from table1, table2 b
  where a.pk1 = b.pk1 and
  a.PK2 = b.pk2 and
  a.PK3 = b.pk3
  less
  Select pk4 from table2
  )
  ) s
  Set s.col1 = 'I ',.
  s.col2 = null;
  
  Table1 is a base table and the primary key for this table is made of CP1, CP2, pk3, pk4.
  Table 2 is a temporary table with no primary key column.
  My goal is to update the columns of table 1.
  I'm using the code above in a procedure and this error:
  ORA-01779: cannot modify a column that is mapped to a table not preserved key
  I'm sure that the error has to with the foregoing update statement.
  
  I have read a few articles and realize that Oracle can understand what table to update in this scenario. But I am at a loss to rewrite this query.
  Please advice, how I can rewrite this query.
  
  Thank you!

  Hello

  Instead of updating a view online, update your actual table, like this:

  UPDATE   table1
  SET      col1     = 'I'
  ,      col2     = NULL
  WHERE      (col1, col2, col3, col4) IN
        (
            SELECT  ...
            FROM    table1
            JOIN    table2  ...
        )
  ;
  

  I hope that answers your question.
  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.
  If you ask on a DML statement, such as UPDATE, the sample data will be the content of the or the tables before the DML, and the results will be the State of the or the tables changed when it's all over.
  Explain, using specific examples, how you get these results from these data.
  Always tell what version of Oracle you are using.

• Decode function in the Update statement

  Hi all
  
  I'm writing a query where I can update a pastdue_fees column in a table of book_trans based on a difference between the return_dte and due_dte columns.

  SQL > SELECT

  DECO
  ----
  Null value
  12
  Null value
  0
  
  If the logic is that, if the sign is - 1, the value in the return_dte column must be 0; If it is + 1, then it has 12 and everything else is Null.
  
  So now, I have to conclude my function of decoding of the update statement to update the columns. However, I get the error messages.
  
  The logic should be:
  UPDATE book_trans SET PastDue_fees = decode (expression)

  If you really really really want to update the entire table, the syntax would be...

  UPDATE book_trans
     SET
        pastdue_fees  = DECODE(SIGN((return_dte - due_dte)*2), -1, 0, 1, 12, Null);
  

  I took out all the single quotes. If you actually have a string column and store all numbers in there so it must be reported as a NUMBER column and not a column of type character (varchar2).

  ALWAYS use the appropriate data type, it will save you a ton of headaches in the future.

  Also, since you are new to the forum, please read the FAQ to learn etiquette and what not.
