• Commit to taking a lot of time for the update statement to bulk - 11 GR 2

  Hi team,

  We have a source table, which is the main table for our application.

  When I commit a transaction after update block, it takes long about 2 to 4 minutes.

  I don't understand why it takes too long...

  Could you please help me on this fix, please...

  It's the details on the table,

  Total number of records: 35 M record

  Validation interval: 500 records / commit

  Total scores: 3

  total number of columns: 95 - including primary, unique and foreign key columns (all columns will be updated for each update because update from the app online)

  Total no of the foreign key columns: 12

  Unique key column: 1

  Total index: 27 ( including the key index foreign 12 + 1 + 1 index of primary key Unique key index )

  example of update statement,

  UPDATE DIRECTORY_LISTING_STG
  SET
    COLUMN_1 = :VAL_1
    .
    .
    .
    COLUMN_94 = :VAL_94
  WHERE RECORD_KEY = :P_KEY_VAL;
  
  

  The table is.

  line-by-line UPDATE is slow by slow transformation

  In Oracle no other session can 'see' upgrade from uncommitted changes.

  The only way to significantly reduce the elapsed time is to have only 1 UPDATE & 1 COMMIT!

• SQLite Update statement

  I have a database in my application, and part of it (obviously) will require the user to update the database with the current information.

  There are 24 columns of the table, and I have my update function works almost 100%, except that there are two drop downs, and when the user updates the record individual everything that is selected in the fall of two downs, is applied to all records.

  My update statement is like this:

  var statement:SQLStatement = new SQLStatement();statement.sqlConnection = connection;statement.text = "UPDATE TABLE SET " +      "OneFish=?, " +       "TwoFish=?, " +       "RedFish=?, " +       "BlueFish=?, " +          // CONTINUES AS TEXT INPUTS DOWN TO       "DropDown1=?, " +     "DropDown2=?, " +          // FEW MORE TEXT INPUTS THEN                "WHERE RECORD_ID=?";       statement.parameters[0] = OneFish.text;       statement.parameters[1] = TwoFish.text;       statement.parameters[2] = RedFish.text;       statement.parameters[3] = BlueFish.text;          // CONTINUES AS TEXT INPUTS DOWN TO       statement.parameters[17] = DropDown1.selectedItem;        statement.parameters[18] = DropDown2.selectedItem;          // FEW MORE TEXT INPUTS THEN        statement.parameters[23] =                FishOption.selectedItem.RECORD_ID;                statement.addEventListener(SQLEvent.RESULT, updateWorked);                statement.addEventListener(SQLErrorEvent.ERROR, updateFailed);                statement.execute();
  

  ALL updates day very well and shown to the a specific RECORD_ID. However, the decline in the bottom change overall.

  This does not happen on my service of "addFish". Someone out there have any ideas why this is?

  Update: It isn't my SQL. If I close the application and then go back, the changes show correctly. The drop down menus are simply not refreshing properly after the update of the database.

  J.Rab!

  I literally JUST thought out and sat next to the woman to rejoice with the laptop on my lap! Then the BlackBerry made his small notification and I said out loud, "oh look, it's probably somebody tell me what I did wrong before that I could update!

  Had dinner and a record label with a look at it to understand.

  To display the resulting data & update fields, I was setting the command prompt from the drop down menus! I went my output and changed function use the selectedItem and success!

  I also forgot to include a refreshTheDatabase(); at the end of my updateFunction() function call;

  I hit a brick wall with this for several hours this afternoon and I can't believe it was that simple! I should have got up and walked away earlier!

  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 235 235

  NULL NULL NULL NULL 24556 24556

  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

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

• Update statement

  Hi friends,

  Need your help with an update statement.

  Update t set t.icode int_tab =.

  (select ac.icode in the ac_tab ac, ed edition

  where ac.current_code = ed.unit)

  where ed.process_no = t.action_no);

  where ed.process_no = t.action_no

  *

  ERROR on line 4:

  ORA-00904: "ED". "" PROCESS_NO ": invalid identifier

  Basically, we need to update int_tab.icode with ac_tab.icode where ac_tab.current_code = edition.unit

  Thank you very much

  I suggest you MERGE. Inside () I call "source" can be controlled carefully. And then you can easily do the UPDATE

  No funny Executive plans and if he SELECT jobs, UPDATE works as well.

  MERGE into the target int_tab

  USING (SELECT t.rowid, rid, ac.icode,

  Of ac_tab ac

  Join IN-HOUSE ed Edition

  ON ac.current_code = ed.unit

  Join IN-HOUSE int_tab t

  ON ed.process_no = t.action_no

  WHERE t.icode! = ac.icode

  and t.icode is not null) source

  on (target.rowid = source.id)

  WHEN MATCHED

  THEN UPDATE set target.icode = source.icode;

• 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.

  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."

  (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.

• the update statement modidy

  Hi all

  I have here is the update statement in my code

  UPDATE equip_stg stg

  SET stg.err = 'WRC '.

  WHERE DOES NOT EXIST (SELECT *)

  FROM (SELECT stg.*

  Of equip_stg stg.

  REASON_SETUP sea

  WHERE stg.equipment_fk = mer.equipment_pk

  AND stg.downtime_reason_code = mer.reason_code

  AND ((stg.status = 3 AND sea. REASON_TYPE = 1)

  OR (stg.status = 2 AND sea. REASON_TYPE = 3)

  OR (stg.status = 1 AND sea. REASON_TYPE = 4))

  ERS stg.downtime_reason_code AND IS NOT NULL)

  WHERE ers.equipment_fk = stg.equipment_fk

  AND ers.downtime_reason_code = stg.downtime_reason_code

  )

  AND stg.status IN (3,2,1)

  AND stg.downtime_reason_code IS NOT NULL;

  The statement above sets updated the column equip_stg in WRC if err for corresponding material and reason, there is no line in the REASON_SETUP table.

  I want to change the code above so that the validation above is first done with REASON_SETUP according to equipment and column of type of reason. Is there is no line for this type of material and the reason in this table, then he must hit lookup table.  Example, I have data from equipment EQP1, status = 3, then it should check if REASON_SETUP has everything save for EQP1 equipment and the reasoning of type 1. If she made the next record should be validated on the table otherwise come file should be validated against the lookup table. For the table of choice also I have same join conditions

  STG.equipment_fk = lookup.equipment_pk

  AND stg.downtime_reason_code = lookup.reason_code

  Thanks in advance.

  Kind regards

  Amrit

  Hello

  I think I see.  All lines for each (equipment, reason_type) will be removed completely on a table or another. reason_setup if possible and looking as if this combination never occurs in reason_type.  Another way to say it is that you want only (equipment, reason_type) groups of the best tablle, where reason_type is better than search.  Exactly what made a Request Top - N .  Here's a way to do it:

  UPDATE equip_stg

  SET err_code = "WRC".

  WHERE (equipment, downtime_reason_code) NOT IN

  (

  WITH union_data AS

  (

  SELECT 'A' preference AS, reason_code, reason_type, equipment

  OF reason_setup

  UNION ALL

  SELECT equipment, reason_type, reason_code, 'B' AS preferences

  SEARCH

  )

  got_r_num AS

  (

  SELECT equipment, reason_type, reason_code

  DENSE_RANK () (PARTITION BY MATERIAL, reason_type

  ORDER OF preference

  ) AS r_num

  Of union_data

  )

  SELECT equipment

  DECODE (reason_type

  1, 3

  3, 2

  )

  reason_code

  OF got_r_num

  WHERE r_num = 1

  )

  ;

  To see how this works, reconstruction of the NOT IN subquery, step by step.  First run just union_data as a stand-alone application.  When you understand what it does, run got_r_num and when you see what he's doing, run the set NOT IN subquery.

• Helps when a special character and is included in the update statement

  Hi gurus,

  
  Please suggest me here. Your help is greatly appreciated.

  Am wririting an update statement on a column called Phone_num.description varchar2 (40).

  
  Here is my update statement:

  
  UPDATE Phone_num
  DESCRIPTION SET = "Beta - EMV / not for the purpose of Production."
  WHERE DIAL_NUMBER = 18662307528
  AND DESCRIPTION =' to & VERIZON';

  
  Here is the structure of the table:

  Phone_num. Description varchar2 (40)
  Phone_num. DIAL_NUMBER Number (11)

  Sample data:

  
  So when I run the sql script it pop-up is to highlight.

  Please suggest how I can handle this.

  Hello

  As John said, the easiest thing is just to disable the functionality of substitution of variables, saying:

  SET DEFINE OFF

  before the statement.  If you need to re - enable this feature, then tell

  ALL SET ON

  just after the statement.

  If you can't do that, then break the literal string in 2 parts immediately after the & character, like this:

  UPDATE Phone_num

  DESCRIPTION SET = "Beta - EMV / not for the purpose of Production."

  WHERE DIAL_NUMBER = 18662307528

  AND DESCRIPTION = ' to &'. | "VERIZON";

  You can't have a substitution variable whose name starts by ', then SQL ("more does not interpret &" as meaning a substituton variable.)

  The "PFA_NPCOFACTMES_103" index is partitioned. I don't know if it's related to this issue:

  SQL > select table_name, uniqueness, separated from all_indexes where index-name = "PFA_NPCOFACTMES_103";

  TABLE_NAME UNIQUENES BY

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

  PFA_NPCOFACTMES NON-UNIQUE YES

  Why the update does not generate as much "becomes"?

  Thanks in advance,

  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 ;-)

  merge into FUS PFA_FUSIONFACC

  a_l'_aide_de)

  SELECT

  NPC. COD_FACTUcaRA AS COD_FACTURA

  NPC. TOT_BASEIMPO_E AS TOT_BASEIMPO

  NPC. TOT_IMPEMI AS TOT_IMPEMI

  OF NPC, CTA AUX_CTAFACTU PFA_NPCOFACTMES

  where

  NPC.cod_postal = CTA.cod_postal

  AND NPC.cta_facturac = CTA.cta_facturac

  ) cta

  (TBT. CTA_FACTURAC = WAS. CTA_FACTURAC)

  When matched then update

  Was SET. COD_FACTURA = cta. COD_FACTURA

  was. TOT_CARGO_DB = cta. TOT_BASEIMPO

  was. TOT_CARGO_FB) = cta. TOT_IMPEMI

• 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

  Bolo

  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!

• Cancellation-TBS and very large update statements

  Hello

  to be sure that I'm right...

  Currently, it need to update a table with 230.000.000 lines. A single statement attempted to update 14.000.000 lines, but this update statement failed after 29 hours with ORA-015555.

  1 how long Undo-TBS store blocks? Only until the validation of the actual transaction, isn't?

  2. on the table, we have 7 index on columns. Is it true, that we can reduce the amount of Undo-SCT for this operation if we remove some clues?

  Kind regards

  Mark

  Ask DBA_SEGMENTS or DBA_ROLLBACK_SEGMENTS for segments Undo and V$ UNDOSTAT for usage of Cancel.
