Count queries and hierarchical

Similar Questions

• What is the difference between write queries and written per second in vCOPs?

  I had on my farm performance problem, when I try to understand by vCOPs I noticed there are two similar measures write queries and writes per second.

  Do you know what is the different between the two measures?

  IO reqs vs real E/s is written. Reqs will be usually higher and includes administrative scsi commands. Written per second is closer to PAHO are / s.

• Legacy and hierarchical queries

  Hi all

  Using the RDBMS 11.2.0.3, I would like to know if there was a way to "inherit" a parent row values when you use a hierarchical query.

  For example, with these values:

  CREATE TABLE foohh (
   id NUMBER,
   parent NUMBER,
   name VARCHAR2(64),
   continent VARCHAR2(32)
  );
  
  INSERT INTO foohh VALUES ( 1, null, 'United States', 'AMERICA' ) ;
  INSERT INTO foohh VALUES ( 2, 1, 'California', null ) ;
  INSERT INTO foohh VALUES ( 3, 2, 'San Francisco', null ) ;
  INSERT INTO foohh VALUES ( 4, 3, 'Golden Gate', null ) ;
  INSERT INTO foohh VALUES ( 5, null, 'China', 'ASIA' ) ;
  INSERT INTO foohh VALUES ( 6, 5, 'Beijing', null ) ;
  INSERT INTO foohh VALUES ( 7, 6, 'Great Wall', null ) ;
  
  

  I would like to be able to view the continent of all lines.

  The following query returns the leaves, but I don't see their continent:

  SELECT
   id
   ,connect_by_root(parent) parent
   ,sys_connect_by_path(name, '-->') path
   ,nvl( continent, 'unknown' ) continent
  FROM foohh
  WHERE
   connect_by_root(parent) is null
   and connect_by_isleaf=1
  CONNECT BY PRIOR id=parent
  ;
  
  

  CONTINENT OF PARENT ID PATH
  ---------- ---------- ------------------------------------------------------------ ------------------------------
  4-> United States-> California-> San Francisco-> Golden Gate unknown
  7-> China-> Beijing-> great unknown wall

  Is there a clever way to do this?

  Thank you

  Anthony

  Include below in him SELECT query.

• Synchronization of AO and output counter, arming and triggering the sequence of events

  Hi all

  I'm trying to synchronize a counter (used as a digital pulse) and analogue of a custom waveform output read from the file on a USB-6211. The goal is to always have these running until I hit 'STOP' and to be able to change the position of the pulse relative to each other. I created a VI by combining and modifying the Cont.Gen.Wfm.Int - Clk.Non - Regen.VI and the Continous.VI Gen dig Pulse Train and I'm now able to produce the two signals to the desired frequency, but I can't seem to get the "Initial period" to work correctly. The values that I come home do not seem to match what is happening LeRiz, and the spacing seems to vary from run to run (within each series is constant). In a previous post, Alfred has suggested:

  "Trigger counter outputs out of the trigger to start AO and adjusting the setting 'Initial period' should give you what you are looking for."  Don't forget to start the tasks of meter in the software before the tasks of the AO (if they are armed and ready to go before the start AO is sent). »

  (link here)

  I tried to use the controls and the propertynodes (perhaps incorrectly), but it doesn't seem to make a difference.

  I think what happens is that my arms and firing sequence is not done correctly. I read on as much information as I could about the outbreak and armament, but I don't know that I understand correctly. Most of the examples I found using an external trigger or perform analog input tasks finished. Does anyone have a suggestion on how to start my two tasks in the proper order? Is something else is wrong here?

  Thank you

  Gabe

  P.S. I have attached the VI and a sample waveform read.

  Hi Gabe,

  This is a cleaned of the VI version that should work (you need not adjust the initial deadline on the right fly?).  Instead of reading a file, I made just a simple square wave of 50% to be used for the test.

  Best regards

  Thank you very much in advance

  You can not use connect by bypassing a hierarchical structure.

  What you get is an output like the one you want without using you connect to.

• mutation in the triggers table problem (need to COUNT (col) and MAX (col) of table shot)

  I was looking for the solution and find many examples, but I do not know what is the best in my option and don't understand everything.

  I realized that can't do a SELECT query in the table where trigger is triggered. But I have need SELECT COUNT (col), then MAX (id) of this table, update some statistical info...
  And also need to row id update, so I can't do trigger of table instead of relaxation of the line.

  
  

  So this is my TRIGGER:

  create or replace

  update_stat relaxation

  AFTER UPDATE ON TABLE1 TO EACH LINE

  DECLARE

  juice FLOAT;

  all the NUMBER;

  end NUMBER;

  BEGIN

  IF (: old.ended <>: new.ended) THEN

  SELECT COUNT (id) FROM end FROM table1 WHERE fk_table2 = new.fk_table2 AND finished = 1;  -Error in the table of mutation

  SELECT COUNT (id) FROM everything FROM table1 WHERE fk_table2 = new.fk_table2; -Error in the table of mutation

  Juice: = ((end /all) * 100);

  UPDATE table2 SET suc = success WHERE id =:new.fk_table2;

  END IF;

  END;

  I also tried with

  pragma autonomous_transaction; 
   
  trigger body....AND
   
   
  commit; 
  
  

  But don't working right when insert more records.

  Thanks, Urban

  At startup, the evening only replicate with the error above.
  
  My question is:
  Why is an update performed at Target.Directory table with the WHERE clause used in the SELECT query to my SNIPPET, which in turn, was intended for the SOURCE. TEST and SOURCE. CONTACT tables?
  
  Published by: MadhuGopanna on October 14, 2012 23:25: fixed select query. Same recurring error.

  "to replicate (exlisitly give source.test as a source)-
  Question: If I mention only source.test as a source, would have extracted ignore changes made to source.contact_no?

  Stating that -

  MAP source.*, TARGET target.directory
  

  sandbox say GG to you that you have what it takes to replicate all tables in the source schema in target.directory. -So, it's nonsense.

  "to extract (add section TABLEEXCLUDE to exclude the replication source.contact_no) -"
  Question: I want to reproduce the combination of test and contact_no of source data in the target.directory table. In this regard the TABLEEXCLUDE of source.contact_no will provide the desired result?

  TABLEEXCLUDE clause do not exclude the possibility of using the table in queries in SQLEXEC or anywhere else. He just exclude the table replication if you use wildcard characters.
  For example -.

  TABLE user.*;
  TABLE user.TEST;
  

  each user of schema table would be replicated except user. TEST.

  I think it is the right way to say what you want-

  EXTRACT ext1
  --connection to database--
  USERID ogg, PASSWORD xxxx
  --hostname and port for trail--
  --rmthost db-dev-2, mgrport 7809
  --path and name for trail--

• Queries and remote databases

  We support 3 databases(A,B,C) different society with the same exact structure for each of them and they all use the same
  request. How can I ask a common table (but each in its own location from database) to all three? Each data base of the company has an Employee table, I want to be able to dynamically retrieve records from this table using the employee login id. Ex:
  Select * from employee where id = '44553';

  Create view all_company_employees as
  Select * from employees
  Union
  Select * from employees@company2_db
  Union
  Select * from employees@company3_db;

  Then you can write queries such as:
  Select * from all_company_employees where emp_id = 10101;

  The 'emp_id = 10101' predicate (or whatever your query predicate supplies) should be automatically pushed on all remote queries, so if there is an index on emp_id, to each of the remote tables, it should be properly used.

  Hope that helps,

• How to get the total line count COUNT (*) SELECT and put on a page?

  Hello
  
  I use JDeveloper 10.1.3.4. I need get the total number of rows in a table and display it on a page and the problem in doing so. At the sqlplus prompt the row count simply would be, for example:
  

     select count(*) from BILL;

  I wonder if having this simple number must be so complicated and if there is more simple, better ways. Here's how I do it and the problem encountered.
  
  1. the name of the page to display the number is summary.jspx. It has a grain of support that "summed" as the managed bean name in faces - config.xml, and the name of the bean class is "summary." The component output on the page is:
  

  <h:outputText value="#{summary.totalStudentsCount}"
                binding="#{summary.outputText5}" id="outputText5"/>

  2. in summary the bean code is:
  

      private Number totalStudentsCount;
      public static int NUMBER = Types.NUMERIC;
  
      public void setTotalStudentsCount(Number totalStudentsCount) {
          this.totalStudentsCount = totalStudentsCount;
      }
  
      public Number getTotalStudentsCount() {
          ZBLCModuleImpl zblcam = getZBLCModuleImpl();
          LoggedInStudentImpl studentTable = (LoggedInStudentImpl)zblcam.getLoggedInStudent();
          String sql = "select count(lsap_uid) from BILL";
          studentTable.setQuery(sql);
          return (Number)CallStoredFunction(NUMBER, "get_total_students(?)", new Object[] {});
      }
  
      private ZBLCModuleImpl getZBLCModuleImpl() {
          FacesContext fc = FacesContext.getCurrentInstance();
          ValueBinding vb = fc.getApplication().createValueBinding("#{data}");
          BindingContext bc = (BindingContext)vb.getValue(fc);
          DCDataControl dc = bc.findDataControl("ZBLCModuleDataControl");
          ApplicationModule am = (ApplicationModule)dc.getDataProvider();
          return (ZBLCModuleImpl)am;        
      }
  
      protected Object CallStoredFunction(int sqlReturnType, String stmt, Object[] bindVars) {
          CallableStatement st = null;
          ZBLCModuleImpl zblcam = getZBLCModuleImpl();
          try {
              st = zblcam.getDBTransaction().createCallableStatement("begin ? := " + stmt + "; end", 0);
              st.registerOutParameter(1, sqlReturnType);
              if (bindVars != null) {
                  for (int z = 0; z < bindVars.length; z++) {
                      st.setObject(z + 2, bindVars[z]);
                  }
              }
              st.executeUpdate();
              return st.getObject(1);
          }
          catch (SQLException e) {
              throw new JboException(e);
          }
          finally {
              if (st != null) {
                  try {
                      st.close();
                  }
                  catch (SQLException e) {
                      throw new JboException(e);
                  }
              }
          }
      }

  The idea of calling a stored function usnig as a "helper" method is 25.5.3 in the Developer's guide, which is closest to you in my need. It's for the functions with the one IN argument; but in my case, the function is not any argument IN. That's why, when you call the helper method CallStoredFunction(), I gave an empty as the last argument and amazing array that caused the problem:
  

  return (Number)CallStoredFunction(NUMBER, "get_total_students(?)", new Object[] {});

  3. the registered function has been tested and works fine at the sqlplus prompt:

  create or replace function get_total_students
     return NUMBER
  AS
     v_student_count NUMBER;
  BEGIN
     select count(ldap_uid)
     into v_student_count
     from bill;
     return v_student_count;
  END;

  4. when the summary.jspx page is run, the browser is full of error messages, the first long line is here (I have split several online for ease of reading):

  javax.faces.el.EvaluationException: 
    javax.faces.el.EvaluationException: 
      Error getting property 'totalStudentsCount' from bean of type 
      zblc.viewcontroller.backing.staff.Summary: oracle.jbo.JboException: 
        JBO-29000: Unexpected exception caught: 
          java.sql.SQLException, msg=Missing IN or OUT parameter at index:: 2

  Thus,.
  (1) what is the problem? What is this parameter IN or OUT of {color: red} index: 2 {color} consult? It has to do with the empty array as the last argument in the call to the helper method?
  (2) this approach is an overdose, and are there more simple and better ways?
  
  Thank you very much for help!

  Hello

  Is there a specific reason why you don't simply create read only object to display with some count (*) as OFCASES from MYTABLE and then just drag and drop the attribute ofcases in page?

  Kind regards

• What is the most efficient SQL to identify the best 5 count indictment and the rest of the Group?

  Hi all
  
  I expect advice about the best way to solve the following (without use of subqueries and decode etc.):
  
  We have a person table that includes the nationality column... we want to identify the top 5 (County) nationalities and the remaining sum is considered to be "the other". We would then use this result to create a pie for the organization chart.
  
  Thanks in advance for your time.
  
  Kind regards
  Yahya

  Or for example

  SQL> select   object_type, sum (cnt) cnt
      from   (select   case when rownum <= 5 then object_type else 'OTHER' end object_type,
                       cnt
                from   (  select   count ( * ) cnt, object_type
                            from   all_objects
                        group by   object_type
                        order by   count ( * ) desc))

• counties-iMatch and - play

  Hello

  Recent subscribe to iMatch, I am happy that I can now access my entire library of all devices.

  One thing that disappoints songs played on my devices does not update the number of game on the library on my mac as before after a sync.

  Information is shared between the devices.

  They is a solution for this?

  Works as expected here, although it is a few unpublished rules of how many, or which parts of a song should be played before the County is advanced.

  Confirm that iTunes > Preferences > sharing > the option on the update verified account game devices and computers.

• WMP freezes, playback and time counter freeze and after a few seconds it will start from the point where it stopped.

  Original title: WMP 11 continues to stop audio playback

  I use WMP 11 for months with no reading problems but since yesterday evening he continues to stop for about 20 seconds every five minutes or so. When she did this, WMP freezes - meter reading and time to gel and I get the hourglass - and then after 20 seconds or more, the trail starts from where it stops. What is happening on all the tracks I did not play a single. I tried 20 audio files (mp3 all) through a dozen different albums. In addition, the gap between tracks seem longer than usual. I feel that it is looking for the data and playback stops because the time it takes to find the data is longer than the amount of data he has for playback? Either way, my files are stored on an external drive, and I'm now ask to update WMP for 'monitor folders' once again.

  I also downloaded a new copy of WMP 11 but this has not fixed the problem.

  I ran Fix It from Microsoft, but it has not to report any issue so I'm stumped. Any help appreciated thanks.

  Laptop Dell Inspiron 1300
  Windows XP SP 3
  WMP 11 - updates enabled
  Active Windows updates
  MSE firewall on / updates enabled

  Registry fixers never used because they can damage the file system!

  Thank you, Anoop - I notice that it is 7 - t - it too much work for XP? I'll take a look, although I found closure and restart toured (as far as the burning problem goes). Thanks for your help.

• BlackBerry smartphone BLACBERRY 8700: e-mail - mail unopened count increases and can not be reset to zero (0)

  For reasons I do not understand that my Blackberry began to show a false accounts of unread mail. With all the read mail now shows 5 to electronic mail notification icon screen, started with 1 first, then 2, now 5. I tried to find a reset for this function but can't find it. Can anyone help solve this mystery?

  Recognizing

  KMH

  First try to reset the device by removing the battery for 30 seconds and then replace it. After the device finishes restarting check the new message indicator. Navigate through your list of messages, click on the menu button, choose view saved Messages. Make sure that no unread messages are there.
