  1. How can I spawn multiple threads in oracle?

  You can schedule jobs to run in another session (this is different from normal multithreaded development because you do not inherently have the ability to monitor or kill the other sessions you have created, those other sessions conducted with completely separate transactions, etc.) using the DBMS_JOB and DBMS_SCHEDULER, package i.e.

  DECLARE
    l_jobno NUMBER;
  BEGIN
    dbms_job.submit(
      l_jobno,
      'BEGIN INSERT INTO table1 SELECT * FROM someOtherTable; END;',
      sysdate + interval '10' second
    );
    commit;
  END;
  

  hourly, a new session to be created in 10 seconds to run your insert statement. You could plan as many jobs as you like.

  2. which is the best way to use when these inserts occur several times in a day at unexpected times?

  How many rows you insert?

  And why you copy all the data from one table to the other several times a day at odd intervals? This requirement seems weird - there may be another approach which does not copy all the data from one table to the other.

  Assuming that the data from volume is sufficient to make parallel DML valid, and assuming that the impact on the performance to make the parallel DML is acceptable (i.e. parallel execution means more machine resources will be dedicated to your session, leaving fewer resources for other sessions) I would usually be much prefer to have three DML statements in a single transaction in one sitting than everyone who happened to be executed at the same time to have several sessions of each race a Declaration of single-threaded.

• DBMS_FGA & DML statements

  Hello
  
  
  I was able to set up and configure FGA in my database and get my SQLs get connected in DBA_FGA_AUDIT_TRAIL. However my requirement is to put the DML statements from the front of the table triggers.
  When I run an insert/update/delete statement against a table say i.e. EMP.  I would llike to see education performed in the front insert/update / deletion of the respective table triggers.  But even after configuration FGA i.e of Audit policy for the EMP table I am unable to get all records if inserted in DBA_FGA_AUDIT_TRAIL when I ask this view BEFORE the trigger Update of the table
  
  How to get my DML statement or clause of the DML where atleast in my before triggers. Please help in this regard.
  
  I went through the links and documents below, but none of that speaks my requirment.

  10g: Fine grain auditing (Doc ID 266896.1()
  How to use DBMS_FGA with a complex audit_condition (include/exclude multiple users) (Doc ID 832856.1()
  
  Thanks in advance

  I make my own comments of Nicolas - it doesn't make much sense to check if an UPDATE statement updates of each row in the table.

  If you don't want to verify such a thing (it being understood that it is almost certainly a bad idea), the classical approach would be to have
  -A BEFORE level trigger UPDATE statement which has initialized a collection
  -A BEFORE the UPDATE to the row-level trigger who populated the collection (i.e. Add the primary key for each update of the collection line)
  -AFTER level trigger UPDATE statement which compared the number of rows affected number of rows in the table

  If you want to get the SQL statement that caused an audit event to end grain, you are probably looking for

  SYS_CONTEXT( 'USERENV', 'CURRENT_SQL')
  

  But trying to use it to determine if each row is updated in the way you mentioned sounds even worse than three trigger approach.

• 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

  937454 wrote:

  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;

• Procedure Oracle can run simultaneously?

  Hi Experts
  
  Procedure Oracle can run simultaneously?
  
  Here's my concern, my procedure is already started manually and according to the times calls the same procedure by another application at the same time, so now procedure can work simultaneously or it will display an error message?
  
  Please explain
  
  Thanks in advance

  Multiple instances of a procedure can be executed at the same time...

  It will cause problem - that will depend on what you do in the procedure...

  For example, if the procedure seeks to change the same data even time in various forums, it will cause problems...

• Excuting multiple sql statements

  Hi to everyone.
  
  
  
  I am quite new to Oracle, even though I have a great experience with SQL and MySQL commands. I am facing a problem that I guess it's really Basic.
  
  
  
  I got a dump of an Oracle database in a format .sql. I mean that the schema and data are built thanks to a large number of sql statements. In particular the schema is done by many 'create a table... '. «While the data are built through «insert into...» ». My need is to import these databases into a new Oracle Oracle 10 g XE database.
  
  
  
  I installed it on a Debian system, and I can properly run a single SQL command both through the web interface http://localhost: 8080/apex and logging as user oracle through the name of sqlplus user/passwd command.
  
  
  
  My problem is that the data is spread over approximately 12000 SQL «INSERT INTO...» "so all one by one run might be a bit boring :-)
  
  
  
  < u > so I ask if there is a way to tell Oracle to execute multiple SQL statements he read a file (like MySQL for example). < /u >
  
  
  
  I'm planning to write a script to do if there is no better way. I know there's no way to dump databases Oracle, but I can change the .sql format since it's the only one I had.

  in SQL * Plus you can run a SQL file with the start command or the abridged version: @

  SQL> start filename.sql
  
  or 
  
  SQL> @filename.sql
  

• Prevent the business rule to run simultaneously

  Hi all

  We are on Hyperion Planning 11.1.1.3.500. One of our business rules makes the system completely meaningless with its results when some users are running at the same time. A person must have been necessary a HBR not to run when it is already running. I need your suggestions to avoid the business rule to run simultaneously.

  Thank you

  Hello

  • tell users check the console to work first, before you run the rule.

  or

  • have a member of the system in your dimension that you can use as a flag. You set it to 1 as the beginning of the rule to indicate he runs, 0 / #Missing at the end of the rule to indicate is finished. You then add a @RETURN to leave the calculation if this flag is set to 1 in your rule. Just be careful about this because if for any reason the calculation fails, or is killed by an admin then your flag is set to 1, but you can still have a form of admin to reset these flags easily if necessary.

• 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?

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