• Re-run a single SQL statement on several report page

  Hello

  I have a Page containing reports 3 and I was wondering if it is possible to re - run only one of these reports using a button or preferably a Select list that allows me to choose which 3 reports I want to ' Refresh/re-run '. I'm wrong completely here but I assumed that you choose the option to send a Page causes all regions to refresh that is re - run SQL queries, they are "based on". Any suggestion or correction to my hypothesis would be welcome.

  Kind regards

  Is it realistic for me to see the results, I think using this method?

  Is - it there any activity in the other database sessions that will result in CUSTOMER_NR is incremented? If this isn't the case, then no, it not there no possibility to see any increase in the numbers. If you have a defined sequence and report on it, then refresh the reports will show a difference:

  You may need to do something, the case is:

  SQL_ID "fphtjnquzzpud" was performed * 38,800,468 * times during the study period.

  38,800,468 time * 0,000016 seconds = 620.807488 seconds = 10 minutes, 21 seconds

  Maybe it's not the time it takes but rather the number of executions?

  Have you considered pinnig the table of SUBSCRIBER in the KEEP buffer pool?

  This is not unusual. Another app could analyze for example hard the most often used SQLs in upstairs app - making benefit of further processing (in theory) of sweet analysis when you use these SQLs.

  In fact, I remember reading something to this effect as a performance for some factor or another Oracle document or note?

  So unless you have serious questions of shared pool, why bother with these sliders? What would be the problem?

• don't forget the select result of a statement to be used several times in the procedure

  Hi all

  I'm sorry for this kind of question, I'm not newbie, but still need your help.

  My need is remember the select result of a statement to be used several times in the procedure.

  My first guess is to use a temporary table, but I think there's better decisions.

  For example, I should make a heavy request

  Select the code from table_function (param1)

  Then, this query is used to insert a list of the id in table1, delete table2 and update in table 3.

  Help me please do not use if possible temporary tables.

  If there is more than one column, you need to create an object type at the database level. Create a collection of this type of object in the procedure.

  Example:

  CREATE OR REPLACE TYPE "OBJ1" as OBJECT(
          column1 varchar2(256 CHAR),
          column2 varchar2(35 CHAR)
          );
  
  CREATE OR REPLACE TYPE "nt_obj1" as table of OBJ1; -- this could be done at procedure level as well
  
  DECLARE
     t_employee_ids   nt_obj1;
  BEGIN
     SELECT OBJ1(column1,column2)
       BULK COLLECT INTO  t_employee_ids
       FROM table1
      WHERE column3 = NNN
  .............

• Sql statement variable gives several values

  Hello
  
  I have a variable that has sql statement and it gives several values and I want to use this variable in one of the filter of interface condition to filter the data in the source table (which has millions of records).
  
  some could let me know the best method to achieve this scenario.
  
  Appreciate your help.

  You are right. Yesterday, I don't think in this case where the data could be from a different server. But I completely forgot today.
  Ok. Here you can find how to use sys_connect_by_path

  http://asktom.Oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:907278700346567560

  Be careful with the size because I think that there is a limit to what can contain the variable ODI.

  After you have assessed the variable is how it could be used in the filter

  ITEM_TYPE_ID IN (#var_csv_id_list)

• How to 'show' a static pseudo index using SQL statement select?

  Hello again,
  
  I have to post a time of 24 hours as an index. (00:00 - 23:00)
  It's easy, if data are available.
  
  But, if the data are not regularly exist on specific time (the time is not regular, IE: 00:00, 01:00, 05:00, 08:00, 10:00, 11:00, 23:00), then it of OK for a TABLE, but not for a CHART.
  
  Here is the story:
  
  I've written a SQL statement that can 'choose' what to display respectively the time available. The result will appear on the map: days or the time is used for the x-axis and the respective value on axis y.
  Example:
  + If the data consists of 'days' (ie: the last 5 days from now on, 16/07/2012, 17/07/2012, 18/07/2012, 19/07/2012, 20/07/2012), the chart will display these dates on the x-axis.
  + If the data consists of 'hours' (ie: only 1 day, hour 00:00 - 23:00), then the chart shows the hours on the x-axis.
  
  If the 'hours' are not regular, means: there is no data on the specific hours, the result of the query is not as regular, average: the value of X - axis "jumps" irregularly.
  
  Question:
  Is it possible to interrogate our own static value?
  for example:
  Select 'Hello' from dual-> result: 'Hello', 1 column, 1 line
  But how to display it into several lines, i.e.:
  
  Time
  *****
  0
  1
  2
  3
  4
  5
  ...
  ...
  23
  
  
  Note:
  the x-axis on the graph model can be customized only for 1 single mode, example: 'Days',
  but of course it will not appear correctly if the result of the query are "hours."
  This means: I have to find the workaround on the SQL query.

• Date range of calculation with the SQL statement

  I'm sure that there is a way to do this in SQL, but I can't understand it. I can write a PL/SQL script to do it, but prefer to use a SQL statement. My database is the database of Oracle 10.2.0.4.0.
  
  I have a table that contains information such as employee number, service id, and date effective start-up of the person in this Department. There are data in another table I want to update their department number in based on their date of entry in the range. If I could figure out how to correctly select the entry into force, I can do the rest.
  
  I have data such as:
  EMP_ID DEPT_NO EFFECTIVE
  -------------- ----------------- ---------------------
  101 1000 1/15 / 2001
  1050 101 5/24 / 2005
  101 2010 6/8/2008
  101 1000 8/2/2010
  
  I want to write a SELECT statement that returns something like this where the end_date is the eve of the ENTRY into force and the last record didn't an end_date because they are always assigned to this service. In addition, the first record in the column, I won't choose a DEPT_NO because the logic of the entry into force has been added in January 2001, he says if a person started in 1985 they might have zero departments at several times so I won't update all data for this period:
  
  EMP_ID DEPT_NO EFFECTIVE END_DATE
  --------------- ---------------- ---------------- ----------------
  101 1/14 / 2001
  101 1000 1/15 / 2001 5/23/2005
  1050 101 5/24 / 2005 6/7/2008
  101 2010 6/8/2008-8/1/2010
  101 1000 8/2/2010
  
  Here is a script to create the data into a temporary table which can be used to write a SELECT statement. I added two records of employees with different dates.
  
  create the table temp_activity
  (emp_id number (12),)
  dept_no number (12).
  (entry into force);
  
  INSERT INTO temp_activity
  (EMP_ID, DEPT_NO, ENTERED INTO FORCE)
  VALUES
  (101,1000,to_date('1/15/2001','MM/DD/YYYY'))
  /
  INSERT INTO temp_activity
  (EMP_ID, DEPT_NO, ENTERED INTO FORCE)
  VALUES
  (101,1050,to_date('5/24/2005','MM/DD/YYYY'))
  /

• Function used in the view definition is called several times

  I'm writing a view that boils down to the following statement:
  
  SELECT val, val)
  SELECT SYS_GUID() val
  OF the double
  )
  
  Against my expectation, which calls SYS_GUID() twice, resulting in two different values for val.
  
  I have written here as view inline, but it must be a regular view in reality. Is it possible to build this view while SYS_GUID is called only once, even if the resulting value is then selected several times? Naively, I want to affect the outcome of SYS_GUID to a variable, and then select the value of this variable. However, this seems not possible in a view.
  
  New to Oracle PL/SQL. This works as expected in T - SQL SQL Server.
  
  Thanks for any help or insight you can provide.
  
  -Brian

  Hmmm, I have no 11 + available so I can't check a solution, but I would like to test:

  SELECT val, val FROM (
  SELECT SYS_GUID() val
  FROM dual
  WHERE ROWNUM = 1
  )
  

  or

  SELECT val, val FROM (
  SELECT /*+ NO_MERGE */ SYS_GUID() val
  FROM dual
  )
  

  Edit: the no_merge indicator seems to work in 10.2.0.4

  Your contribution is very much appreciated.
  
  Thank you for taking your time to answer my question.

  How will I know (from Plan 1 and Plan 2) whose execution plan chose for the current run?

  Since you're already on 10.2, you can identify the actual execution plan by checking in V$ SESSION SQL_ID and SQL_CHILD_NUMBER column. This can be used to identify the plan in V$ SQL_PLAN (columns SQL_ID and CHILD_NUMBER) and in 10g, you can use the convenient DBMS_XPLAN. Function DISPLAY_CURSOR for the information of the real plan using these two parameters.

  Kind regards

• Using a Bind Variable in the FROM of a SQL statement part?

  Hi all
  
  I have a problem, I am trying to execute a SQL statement. However, I need the FROM part of the SQL statement in a variable binding. This is because the end user will have to choose between 2 views of database.
  
  I tried this:
  Select CON_ID from: P23_DB_NAME where CON_LEGACY_ID =: P23_CONLEG_NO
  
  I had no chance. The error I got was,
  '+ The query cannot be parsed in the generator. If you believe that your request is
  syntactically correct, choose the generic "columns" box below the
  the source of the region without analysis.
  "ORA-00903: invalid table name +".
  What makes sence, but now I'm a little stuck.
  
  Does anyone have ideas for a workaround?
  
  Thanks in advance.
  -N.S.N.O.
  

  The example I gave you is quite simple. You must take some time to study it to see where you need to be very careful what put you where. Now, of course your example does not work becaues you have several errors. It will work for you:

  DECLARE
     x   VARCHAR2 (4000);
  BEGIN
     x := x || 'SELECT CON_ID FROM ';
     x := x || :p23_db_name;
     x := x || ' WHERE CON_LEGACY_ID = ' || :p23_conleg_no;
     RETURN (x);
  END;
