• transactions and failure of DML statement

  Hello

  Say I have 10 DML statements as part of my operation and the 9th one fails (and I have no to autocommit).

  Is it possible to have an exception that deals with this and 10th instruction and allow the validation of the transaction, or the whole operation should be cancelled?

  Thank you.

  Your session will automatically rollback the statement failed. All prior statements remain uncommitted. What you do then, it's up to you.

• 12 c call Webservice JDeveloper get "SQL string is not a DML statement" as a SQLException exception

  Hi guys,.

  I developed a java class to access the database using the OracleDataSource class and run a SQL query with a select statement. It works very well. I have built a wrapper class and as a Web service. I get "SQL string is not a DML statement" as a SQLException exception when I run as a Web service, but it works very well as an application.

  No idea why I get this error? Not sure why WebSercie is having a problem while this works as an application.

  Thank you and best regards,

  Srini Mel

  Solved the problem by myself.

  The first release "SQL string is not a DML statement" is due to an additional line (pstmt2.executeUpdate ()) in the code.

  Second question, receives not the query response is due to bad user input. I walked into 13.21651 instead of 31.21651.

  Thank you!

• Insertion of a DML statement as string in a table column

  
  Hello

  Is there a way I can insert a dml statement (such as "update a SET COL1 = 10") in a table column using a procedure or a function.

  I can do it by simply running an INSERT statement. But how can I do with a proc or function without getting an error "Cannot perform a DML operation inside a query"

  Please advice

  Hello

  In fact, it can be done through a procedure. I was trying to see if I can do this with a function.

  Of course, you can do so via a function; you just can not call this function of a SQL statement.

  If the function returns a VARCHAR2, then you could call it like this:

  DECLARE

  foo VARCHAR2 (100);

  BEGIN

  foo: = fun_a;

  END;

  or like this:

  BEGIN

  dbms_output.put_line (fun_a);

  END;

  How can I get the latest DML statements in each block.
  As SYSTEM. LAST_QUERY returns the last select statement, I need to get the last Insert/Update/Delete statement
  in each block.
  
  Thanks in advance

  Rizly,

  You can use the GET_BLOCK_PROPERTY to get the last query executed on this block.

• Run simultaneously multiple dml statements.

  Hi all
  I have an obligation to perform multiple dml instructions at the same time. I tried to do this using dbms_job, in vain.
  I planned 3 dbms_job at the same time. Each task has a bulk insert statement, inserting into a single target table. Kick off 3 jobs, but there was almost a minute apart.
  Is there another way to do this?

  You can launch 3 separate SQL more sessions, but how run you dml statements at the same exact time?

  My desktop computer, here's how I would do:

  Create a batch back file (for example runall.cmd) that looks like this:

  Start some_command.cmd
  Start some_command.cmd
  Start some_command.cmd

  Then double-click it. This will lauch some_command.cmd in 3 separate sessions. Each will be launched but will not wait to complete before starting the next.

  In the batch file, some_command.cmd, you can have everything you want. But it will probably take sqlplus.exe with command line options (one of them a .sql script).

  That's how I used "Parallelization DIY" of Tom Kite. But I would normally have a parameter (such as a range or something) to keep the LMD are mutually exclusive.

• Why this parallel DML statement is not run as fast as DBMS_PARALLEL_EXECUTE?

  Hello

  I'm on the database Oracle Enterprise Edition, Linux RH 11.2.0.3. I have a pl/sql function that accepts a sdo_geometry (essentially an object with a few varrays), round each number in one of the varrays and retransmits the object.  Here is a version of the function, simplified slightly for brevity:

  create or replace round_coordinates (p_geometry in sdo_geometry, p_round_factor in numbers)

  return sdo_geometry parallel_enable

  is

  sdo_geometry v_geometry: = p_geometry;

  v_ordinates sdo_ordinate_array;

  Start

  v_ordinates: = p_geometry.sdo_ordinates;

  for me in v_ordinates.first... loop of v_ordinates. Last

  v_ordinates (i): = round (v_ordinates (i), p_round_factor);

  end loop;

  Return sdo_geometry (v_geometry.sdo_gtype, v_geometry.sdo_srid, v_geometry.sdo_point, v_geometry.sdo_elem_info, v_ordinates);

  end round_coordinates;

  /

  I need to perform this function as an update DML on hundreds of millions of sdo_geometry objects and according to my estimates it will take weeks.  So, I want to run in parallel.

  The data is in a bunch of tables, some with lines of k ~ 100 more with millions of people.  My preference is to browse the tables and run an update such as:

  Update < table > set geometry = round_coordinates (geometry);

  But I would like to operate in parallel, so I thought that I would allow the DML parallel to the session with

  ALTER session enable parallel dml.

  ALTER table < table > parallel;

  , and then run the update by: Update / * + parallel * / < table > set geometry = round_coordinates (geometry);

  When I do that, I can see a v$ px_session 16 parallel slaves are bent and the plan of the explanation is the following:
  

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

  | ID | Operation | Name | Lines | Bytes | Cost (% CPU). Time |    TQ | IN-OUT | PQ Distrib.

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

  |   0 | UPDATE STATEMENT.             | 10000 |   468K |    43 (0) | 00:00:01 |        |      |            |

  |   2.   COORDINATOR OF PX |             |       |       |            |          |        |      |            |

  |   3.    PX SEND QC (RANDOM). : TQ10000 | 10000 |   468K |    43 (0) | 00:00:01 |  Q1 00 | P > S | QC (RAND) |

  |   4.     ITERATOR BLOCK PX |             | 10000 |   468K |    43 (0) | 00:00:01 |  Q1 00 | ISSUE |            |

  |   5.      TABLE ACCESS FULL | SMALL_10000 | 10000 |   468K |    43 (0) | 00:00:01 |  Q1 00 | SVCP |            |

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

  But the update statement on my test data set does not any more quickly - it takes a few seconds more series that suggests General fresh extra expectations for the management of parallel slaves that's happened, but they did not have the query run faster.

  
  I tried to use the dbms_parallel_execute with the create_chunks_by_rowid option package and parallel_level = 16 With that I get at the end just over 1/16th of the time that it takes to run in series!

  That's fine, so I have the option dbms_parallel_execute, but I would like to understand why the query with the parallel flag does not expedite things.

  Any ideas?

  Thank you

  John

  It may be that the call to the PL/SQL function slows down things. Did you think to do in pure SQL?

  Here is an example:

  update test_sdo tsd
     set tsd.geometry.sdo_ordinates =
         (select cast(collect(round(t2.column_value)) as sdo_ordinate_array)
            from test_sdo t1
                ,table(t1.geometry.sdo_ordinates) t2
           where t1.id = tsd.id)

  BTW: You can parallelize the query part of the SQL but not updating, it's documentation:

  "Parallel DML can be done on tables with columns object provided that the columns of the object are not accessible."

• Trigger to make a difference on the DML statements

  Hello

  I use a trigger on a table:

  Here is the Code:

  CREATE or REPLACE TRIGGER test001
    AFTER INSERT OR UPDATE OR DELETE ON tabletest001
    FOR EACH ROW WHEN (new.org = 43) 
  
  DECLARE
       .....
  BEGIN
  
  IF DELETING THEN 
       INSERT INTO TEMP001 VALUES(.....);
  END IF;
  
  IF INSERTING THEN 
       ...
  END IF;
  
  IF UPDATING THEN 
       .....
  END IF;    
  EXCEPTION
      WHEN OTHERS THEN
            ....
  END;
  

  When the trigger is called to remove the operating instructions inside

  IF DELETING THEN 
       INSERT INTO TEMP001 VALUES(.....);
  END IF;
  

  may not have performed. It is a simple insert statement on a temporary table.

  While his work very well for surgery Update and Delete and respective statements are also get executed.

  Help, please.

  Possible cause: a DELETE event trigger is not 'new', then the condition values "WHERE (new.org = 43)" is never true.

• encrypt/decrypt in Oracle Forms BEFORE you call an SP or the database DML statement

  Hello.  I'm working on an application where we need to encrypt information before it is sent to the database.  I know that the database has a great set of stored procedures to manage the encryption and decryption.  The only challenge here is the fact that I would need to send information unencrypted in the database "in the clear".  Ideally, I would like to encrypt the information in the form and send it to the database.  On recovery, recover the information and then have the application forms decipher encrypted information.

  Whoever did this as a package within a PLL without all calls to a package DBMS_?

  Thank you

  BradW

  OK, I think I have the solution.  We are going to import a java class that we create to do this for us.  We then import it in forms in a library of PLL.  Problem solved!

  Nice little intro to importing Java can be found here:

• dml execution 2 statements at a time with the help of execute immediate

  I would like to run 2 DML statements at a time with the help of execute immediate usefulness,.
  
  ex:
  
  update employee set ename = 'Chantal' where eno = 123;
  Update dept set dname = 'IT' where dno = 345;
  
  I want the two statement to execute at a time, but I don't want to use any loop as well.
  
  Thanks in advance

  You can use:

  execute immediate 'begin update employee set ename='jagadeesh' where eno=123; update dept set dname='IT' where dno=345; end;';
  

  Although updates will always run one after the other.

  If you want the simultaneous treatment, then you need to use DBMS_JOB and DBMS_SCHEDULER to plan both work to run to run each of the statements independently.
