• Performance problem on the SQL query that does not use the primary key index

  Hello!
  
  I have some performance issues on a single SQL query (Oracle 10 g).
  I could solve the problem by using the INDEX indicator, but I would like to know WHY this is happening.
  
  * Tables *.

  When I run this query, the execution plan shows the index using (JobComp_PK and JobComp_IX_Comp).
  No problem.

  of JobComp
  Join jobs
  on Job.id = JobComp.id_job
  where JobComp.id_comp = 134
  /
  -runs in 0.20 sec
  
  But when I add the field 'name' of the work table the plan uses full access table to the table of work
  
  Select JobComp.*, Job.name
  of JobComp
  Join jobs
  on Job.id = JobComp.id_job
  where JobComp.id_comp = 134
  /
  -runs in the 2.70 dry
  
  With the help of the index
  
  Select / * + INDEX (Job Job_PK) * /.
  JobComp.*, Job.name
  of JobComp
  Join jobs
  on Job.id = JobComp.id_job
  where JobComp.id_comp = 134

  This behavior is correct?

  Hello.
  I'm sorry for the plan unformatted.
  The execution time of the querys "without field name' and 'with the field name with suspicion" are equal.
  He has no problem caching, because I get the plans of the sequence different from the querys and repeated the performance. The result is always the same.

  I don't think that there is no problem with oracle crossing LOOP IMBRIQUEE to the HASH JOIN when you include the field name and this should be the expected behavior. But it seems that your WORKING table has a degree of parallelism set against what is causing the query to run in parallel (as JOB table is now available with full table scan, instead of indexed access earlier). It could be that the parallel execution is contributor to extra Runtime.
  (a) do you know why the degree of parallelism on the WORK table has been defined? Do you need it?

  You can see if the following query provides a better response time?

  select /*+ NOPARALLEL(JOB) */ JobComp.*, Job.Name
    from JobComp
    join Job
      on Job.id = JobComp.id_job
   where JobComp.id_comp = 134

• Help with sql query / a subquery to perform the COUNT

  Hello everyone,

  Co-worker colleague asked me to post a request here in hopes of getting more support.  Here's the question:

  There are 3 tables associated with this request.  A table of the application, which displays a number of application open for a particular request, an audit table that shows you all employees who worked on this application and one employee who shows you the details of the employee table.  My colleague is trying to understand what, how to see only applications that have been published by a wizard, but not a Manager.  There are a few applications that worked on both, but he won't see this request in its results.

  Here are the tables

  EMP

  ID	FULL_NAME
  1234	John Doe
  5467	Jane Doe
  2345	Clark Kent
  5432	June Cleaver

  Unfortunately, this table does not have a title column (which was created provider, so we cannot change the internal structure).  My colleague knows who is the Assistant and the Director, then in this case, the first two of the id:

  1234 and 5467 are managers and the other 2 are assistants

  T_APPLICATION

  app_id	app_number	date_opened	app_type
  9018	54778	JANUARY 10, 2014	NETWORK
  9019	54779	JANUARY 11, 2014	DATABASE
  9010	55000	MARCH 12, 2014	MATERIAL

  T_APP_AUDIT

  APP_ID	PROCESSED_BY
  9018	1234
  9018	2345
  9018	5432
  9019	2345
  9019	5432
  9010	5432

  So, here is the actual query, I was given: it is actually to check the number of times that each application has been published per person:

  Select a.app_id, c.full_name, count (*) that controls

  t_application a, t_app_audit b, c of the emp

  where a.app_id = b.app_id and b.processed_by = c.id and

  a.app_type in ('NETWORK', "DATABASE")

  and b.processed not in ('1234, ' 5467')

  GROUP OF A.APP_ID, c.full_name;

  IF I won't see 9018 in my results, since at one time it was edited by a Manager (1234).  Unfortunately, this request does not eliminate the app_id 9018, it eliminates only the name of handlers appear in the query.  I hope I've explained this properly, and any help to point us in the right direction is welcomed.  Thanks in advance.

  Select

  a.app_id

  c.full_name

  , count (*) as the controls

  of t_application one

  t_app_audit b

  c of the emp

  where a.app_id = b.app_id

  and b.processed_by = c.id

  and a.app_type in ('NETWORK', "DATABASE")

  and b.app_id by (not in

  Select app_id

  of t_app_audit

  where processed_by in ('1234, ' 5467')

  )

  GROUP OF A.APP_ID, c.full_name;

• What is the best way to optimize a SQL query: call a function or doing a join?

  Hi, I want to know what is the best way to optimize a SQL query, call a function inside the SELECT statement, or make a simple join?

  It depends on.  Could be a.  Could be the other.  Could be no difference.  You would need to compare with your tables in your environment with your settings.

  If you put a gun to my head, I was given no other information and required that I answered the question, I would tend to wait that the join would be more effective.  In general, if you can do something in pure SQL, it will be more effective than if you call PL/SQL.

  Hello

  Not sure you mean exactly, but maybe you could do something like:

  MHO%xe> with t as ( -- generating your sample data:
    2  select '123' col1, 'johns123' col2, 'edwin321s' col3 from dual union all

    5  )
    6  --
    7  -- actual query:
    8  --
    9  select rtrim ( case when col1 like '%123%' or col1 like 's%' then col1||', '  end
   10         ||      case when col2 like '%123%' or col2 like 's%' then col2||', '  end
   11         ||      case when col3 like '%123%' or col3 like 's%' then col3||', '  end

  RTRIM(CASEWHENCOL1LIKE'%123%'ORC
  --------------------------------
  123, johns123
  seenu, satya123reset

  You mention:

  or print the records begins by a ' as

  However the output desired is not begin with s for 's123' and "stest"... you can adjust your specification or your output...

• Passing the value of the SQL query select list

  Hello

  In my application users have in their homepage to a region which has two simple things, a part of LIST SLECT lov function and a BUTTON

  There is also another page which has a normal life to report which shows the employees.

  
  

  Homepage the user can select certain number of Department in its 'SLECT-LIST' and click 'open '.

  
  

  For example: If the user has selected a DEP_NUM_5 and click on the BUTTON it will be redirected to the page of a report and gets only showed the employees belonging to the Department 5.

  
  

  The report page contains a simple SQL query, and I understand that somehow I must pass the value in the SELECT LIST, where I now have the '?

  
  

  How can I do this, where should I start?

  Of course I would really appreciate an example of code, if anyone has time to do a.

  
  select "EMP_ID", 
  "EMP_FORNAME",
  "EMP_SURNAME",
  "DEP_NUMBER"
  from EMP E
  where E.DEP_NUMBER = ????????
  
  

  Hi Sozua,

  1. create an item hidden on the page where you have the report.

  I say P2_DEPT_NO

  2 assign to that in your sql query

  select "EMP_ID",
      "EMP_FORNAME",
      "EMP_SURNAME",
      "DEP_NUMBER"
      from EMP E
      where E.DEP_NUMBER = :P2_DEPT_NO
  

  below the area source ther is also an option

  Elements of page to submit-> put this element in this.

  for example;

  Page to submit items: P2_DEPT_NO

  3. change your button

  Action: Redirecting to page of this application

  Page: 2 / / assuming that page 2 is the report page

  Place these items: P2_DEPT_NO

  with these values: & P1_SELECT_LIST.  assuming that selection list is on page 1

  Hope this helps you,

  Kind regards

• Loading the XML file with the missing elements dynamically by ODI

  Hi guys,.

  I have the XML with two nodes Employee and address below. On a daily basis, sometimes the address element might not come from the source xml file, but my interface has columns mapped to the elements of the address, and that is why it may fail because of the source element is not found in the file or data could not get charged because the State 'and' in the sql query that is generated between the employee and address elements.  Is there a way where I can load the data dynamically where I can search in the file only for items (used) present and dynamically loading data only for these items?
