make a query in an update statement

• How to optimize the update statement so that the query is reading the same table?

  Hi all

  I have a process with the following UPDATE statement:

  Sales_val update

  SET ship_date =)
  Select max (hist.ship_date)

  FROM sales_hist hist

  WHERE hist. X_ID = A.X_ID

  AND hist. X_VAL = A.X_VAL)

  ) WHERE EXISTS (select * from sales_hist hist where )

  WHERE hist. X_ID = A.X_ID

  AND hist. X_VAL = A.X_VAL

  )

  sales_val - 50 lines mln (unique index)

  sales_hist - 20 mln ranks (unique index)

  I met many problems with waits and locks - how to optimize to avoid locks using the parameters of tables or changes of the declaration? or maybe is there another way to do optimization ?

  Kind regards

  Thank you for that. Collect in bulk Unfortunatelly + FORALL does not work with the types in 10g - solution is to use the FOR loop and is not as effective as FORALL in many cases. I do still some tests to solve this problem - I'll put you once it's done.

  EDIT: hash partitioning + fusion - 3-5 minutes (time), so for now it's the solution to the problem. Thank you all for the great discussion!

• Update statement can be used depending on the result cache?

  Hi all

  I stumbled on an interesting question. UPDATE statement is used in the following function, even if the feature is created RESULT_CACHE. It seems illogical. I was wondering, is it possible?

  If so, why RESULT_CACHE is used?  Because it means "do not execute the function, look for the result of the hash table and return the results to the user ' if the UPDATE statement, so doesn't mean it should run for each call and use with RESULT_CACHE and UPDATE/DELETE/MERGE is illogical or wrong?

  Thanks for your help.

  FUNCTION to CREATE or REPLACE plch_get_data (FULL id_in)

  RETURN VARCHAR2

  RESULT_CACHE

  IS

  BEGIN

  Dbms_output.put_line ('run');

  UPDATE plch_data

  SET nm = UPPER (nm)

  WHERE id = id_in;

  COMMIT;

  RETURN "SUPERIOR."

  END;

  Yes, it's the challenge of PL/SQL quiz - and the point of the quiz is only automatic relies on parsing by Oracle only supports arrays of account that is QUESTIONED.

  The tables that are affected by DML not a query as an update do not figure in automatic invalidation of a cache.

  I was hoping that the explanations given in the questionnaire itself would not lead to a thread - rather it would provide a pleasant and clear answer. So feel free to let me know if you think otherwise.

  As to why Oracle would let you include DML not a query inside a function of caching of result, well... I can easily accept that you shouldn't do this - in general. But I don't see that we should make it impossible. It would probably be a good candidate for an another PLW (PL/SQL warning), as in:

  "Non-requetes DML in a result caching function will not affect caching and can result in unexpected results."

• The single update statement to improve performance

  Hello

  I have a table as shown below and you have written plsql statement, as shown below.

  Collar collar collar collar collar E collar F D C B A

  NULL NULL NULL NULL 124 124

  NULL NULL NULL NULL 235 235

  NULL NULL NULL NULL 24556 24556

  NULL NULL NULL NULL 45645 45645

  NULL NULL NULL NULL 34255 34255

  If the Col is not null then

  Update tableA

  set Col = Col F A;

  Otherwise, if the Col B is not null then

  Update tableA

  game F Col = Col B;

  Otherwise, if E Col is not null then

  Update tableA

  game F Col = Col E;

  Otherwise, if the Col D is not null then

  Update tableA

  game F Col = Col D;

  Otherwise, if the Col C is not null then

  Update tableA

  game F Col = Col C;

  Can combine us these if statements in a unique single update statement.

  Thank you

  Yes to COALESCE. If you could share create table statement with insert sample instructions will make it much easier for others to test and help you.

  for example

  update testcoal set colf = coalesce(cola,colb,cole,cold,colc)
  

• Update statement with multiple joints

  Hello

  I use Oracle 12 c and here my Question:

  /*
  

  ledgerstb is an Oracle the ITO (TransNo column is the primary key)

  vledgerstb_gtt is a global temporary Table

  vledgervc_gtt is a global temporary Table

  * Cause: An attempt was made to insert or update columns in a join finds out who

  map to a table not kept the key.

  * Action: Change the directly underlying base tables.

  For your reference, the following result internal instruction select (in blue color police) give;

  TransNo: 1 STBNo: VAAAABM315711131

  TransNo: STBNo 2: VAAAABM315711214

  TransNo: STBNo 3: VAAAABM315711262

  TransNo: STBNo 4: VAAAABM316410986

  Please suggest if I'm doing something wrong or it is not possible to update the table like that.

  (I know that I can use ForAll Update statement, but I do not want to use Collections here.)

  Thank you carine, finally I found my answer,

  the update query requires that each record that will be updated should be updated only once. so if I do join 1<->1 it updates successfully.

  Thanks to all who contributed, or at least tried. Thanks again.

  I don't know the reason why at first sight, but it is obvious that the inner nested loop was doing a lot of work (full index scan).

  My first thought was to rewrite the query in a merge statement.

  Perhaps leads to a more effective plan and so no need to delve deeper into the issues you have raised ;-)

• line blocking during the update statement

  
  Hello

  Using Oracle 11 g 2. If I call the following update statement of meeting A, meeting A locks the line until a statement commit / rollback is emanating from the session has. If the session B calls the same statement was updated and the same line, session B will have to wait until the lock is released in the session. However, application developers are expressed in terms of discussions. Would it be possible that the update statement is called in the same session by several requests? If so, the case statement can be evaluated without the line being locked which could lead to erroneous results? Trying to keep this short message.

  tableA has column (number of key, primary) and columnB (number)

  {

  Update tableA

  Define columnB = case when columnB = 3 then

  4

  When columnB = 4 then

  5

  on the other

  columnB

  end

  When columnA = 6;

  }

  2 applications (almost at the same time) in the same session could assess columnB 3. The goal would be the first query sets in column 4 and the second request sets in column 5.

  > However, application developers are expressed in terms of discussions.

  Of course, they are...

  But each application thread will have its own dedicated database session.

• 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.

  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.

  Best regards

• 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

  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.
  
  I use Oracle SQL. That's what I have so far for my decoding function:

  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)

  Thank you!

  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.

  On this table there will be duplicate records, but only the column 1, column 2 and 3 on these "duplicate" files will be the same, column 4 will be different (column 4 is not a unique identifier, but if there are duplicate records, it will be different at least 2 records). Column 5 is not yet filled, all null.
  
  I need a way to update column 5 of these duplicate records. However, let me update on one of the folders and the criteria for this will be where column_4 = "Hello".
  
  So far I came with an update statement similar to the following, but I don't know where with her:
  
  UPDATE DANS_TABLE
  SET COLUMN_five = "DUPLICATE".
  WHERE EXISTS (SELECT column_one | column_two | column_three, COUNT (*))
  OF DANS_TABLE
  GROUP BY column_one | column_two | column_three
  SEEN (COUNT (*) > 1)) and column_four = 'Hello ';
  
  For any help, thank you very much! Much appreciated,
  
  Dan

  This is the query that updates that one line duplicated to column_five. I hope this helps...

  UPDATE DANS_TABLE x 1
  SET COLUMN_five = "DUPLICATE".
  WHERE THERE ARE
  (
  Select r_id of
  (select max (rowid) r_id, column_one | column_two | column_three)
  of DANS_TABLE t1 where exists
  (
  Select str of
  (
  SELECT column_one | column_two | column_three str, COUNT (*)
  OF DANS_TABLE
  GROUP BY column_one | column_two | column_three
  SEEN (COUNT (*) > 1)
  ) t2 where t2.str = t1.column_one | T1.column_two | T1.column_three
  ) column_one group | column_two | column_three
  ) x 2 where x 1 .rowid = 2 .r_id x
  ) and column_four = 'Hello ';

• Update statement with Date field

  I'm trying to run an update statement and I want to update the date in the format:
  
  04/05/2010 12:31:54
  
  If I run this query on the double it appears correctly: select the double to_char(sysdate,'DD/MM/YYYY HH12:MI:SS PM')
  
  If I run this well query on my table, I get a 'not one month valid' error.
  
  
  UPDATE WR_MEASURE_VALUE SET HOST_CORRECTED_VALUE = 35,
  HOST_CORRECTED_DATE = to_char(sysdate,'DD/MM/YYYY HH12:MI:SS PM') WHERE WR_MEASURE_VALUE_OID = 474066
  
  
  what I am doing wrong and how can I get my update statement to update date correctly in the ' HH12:MI JJ/MM/AAAA: SS PM' form?
  
  Thank you
  
  
  Guess all I had to say was HOST_CORRECTED_DATE = SYSDATE
  
  Thanks anyway

  If you want:

  'UPDATE WR_MEASURE_VALUE SET ' || p_FieldToInsertUpdate || '=' || v_ValueAfterFactored || ',' ||
                                    v_DateToUpdate || '= to_date(''' || to_char(sysdate, 'dd/mm/yyyy hh12:mi:ss PM') || ''', ''dd/mm/yyyy hh12:mi:ss PM'')'||
  ' WHERE WR_MEASURE_VALUE_OID= ' || v_MeasureValueOID_arr(i) ||
  ' AND ' || v_Current_25Month_Value || ' != ' || v_DisplayValue;
  

  But... smacks of dubious design if you do not know what columns you update at compile time, IMO.

• Performance issue with the Update statement

  Oracle 10204
  
  I have a problem related to updaing one performance table.
  only 5000 lines should be updated.
  Hir are some details on the tables/M.V concerned:
  

  TABLE_NAME     LAST_ANALYZED          NUM_ROWS     SAMPLE_SIZE
  PS_RF_INST_PROD     1/20/2010 1:14:22 AM     7194402          7194402
  BL_TMP_INTRNT     1/27/2010 9:08:54 AM     885445          885445
  NAP_INTERNET     1/25/2010 11:47:02 AM     7053990          560777

  I tried to run the update with two options:
  1. with the plan than oracle choose.
  2. with notes I added.
  In both cases I he collapsed after more than an hour.
  
  Can any one suggest how to speed it up?
  
  Below are for the two option tkprof.
  

  Please note that beside the defualt statistics on those tables i also gathered statistics on two column level as followed:

  The problem in your update statement that is the query in your set clause is executed many times that there are lines in BL_TMP_INTRNT of 'intellectual property' in their column of term_desc. You mentioned there are about 5000, then the query joining NAP_INTERNET with PS_RF_ISNT_PROD is begun 5000 times.
  The trick is to join only once, be updated using join views - provided that it is preserved - key or by using the merge statement.

  Here is an example:

  We used often successfully the clause of the logging of errors during the execution of the batch to the database inserts. However, we now have a situation where an UPDATE statement is default and make back up when it encounters a referential constraint foreign key [ORA-02291]. It registers with success of coercion errors [ORA-02290] Check. Foreign keys are not carried over, and they have nothing to do with unique constraints or indexes on the table that is the target of the UPDATE statement. The logging of errors table was created using the DBMS_ERRLOG package. We have created to make sure that we introduced column format errors. The same problem occurs. The UPDATE statement tries to update about 12000 lines. Any help in understanding this problem would be appreciated.
  
  Here's the error statement
  ORA-02291: integrity constraint (OIFS. FRAME_FK07) violated - key parent not found
  
  Here is the statement of the problem and its PLSQL block surrounding:

  I think and that's just a wild guess, is that your table has a trigger... or an associated view has a relaxing place.

• Update statement with joins of tables and where Clause

  Hi, I have MS SQL background and I try to execute an update statement in Oracle with joins of tables. However, the syntax below does not work but I think it works for MS SQL.
  
  Basically, the base table must be attached to a master table trend with monthly snapshots, an account will be only an entry for a given date monthly. Where clause must be limited to accounts within a certain range of interest rates.
  
  The first approach returns command SQL ORA-00933 not correctly completed, and the second approach returns ORA-01427 row below query returns multiple rows. Can anyone help? Thanks in advance!
  
  
  
  1:
  
  Update PenaltyAll
  Set a.indicator = month (b.)
  of PenaltyAll an inner join Master b on a.acctno = b.accountnumber
  where a.monthend='01/31/2009' and b.date='12/31/2008' and b.apr < 20
  
  2:
  
  Update PenaltyAll
  adjustment indicator =
  (select to_char (b., 'MM')
  of PenaltyAll an inner join Master b on a.acctno = b.accountnumber
  "where to_char (a.monthend,'mm/dd/yyyy ') = 31 January 2009"
  (et to_char(b.date,'mm/dd/yyyy') = December 31, 2008 "
  and b.apr < 20)
