• Eurotherm EPower controller: query problem

  Hello

  I have a problem with communicating with a controller Eurotherm EPower (with 4 units) by OPC server.

  I use:

  -LV 8.5.1

  -iTools OPC Server 7.50 with a number of product formed the social reason (active license)

  -EPower Firmware v3.01

  Communication between LV and OPC server is made by "DataSocket write" and "Read DataSocket".

  I can write => values without problem I only write Main.SP on the evolution of events user and everything's fine.

  But on reading, I would like to read Meas.I Meas.P, Meas.V, continuous for each unit (up to 12 url request)

  The first reading is ok, so I have values, the url are ok. But after that, it is impossible to put in a loop-online no error, (status = 0 on LV and OPC Server) but the values are not updated with the following query.

  I tried to play with the option "wait for updated value", but without success.

  The only way I've found is to open the interface for server, the device, right click and select "Synchronize Active device". But this option is only a shot and very long because, I guess, he gets everything in the device...

  Another point: it works perfectly with the Engineering Studio, commonly called iTools-iTools. It is a client of the OPC server on my application.

  Another point on the other: when I run my application is the ID_EPower.exe in the list of Windows processes and consume resources (0 or 1%) so he lives.

  Complete, with one hour, I thank them but not way with Eurotherm hotline.

  My question is: Y at - it a particular way to obtain ongoing measures such as sending a query each time or a general property to get updated data?

  I used to cruise control disc from the same manufacturer with no problem and no need to send a request to get the values, but here it is perhaps a different case.

  List of requested URL:

  OPC:/Eurotherm.ModbusServer.1/CLA_Gradateurs.192-168-1-222-502-ID001-ePower.network.1.MEAs.V

  OPC:/Eurotherm.ModbusServer.1/CLA_Gradateurs.192-168-1-222-502-ID001-ePower.network.1.MEAs.I

  OPC:/Eurotherm.ModbusServer.1/CLA_Gradateurs.192-168-1-222-502-ID001-ePower.network.1.MEAs.P

  OPC:/Eurotherm.ModbusServer.1/CLA_Gradateurs.192-168-1-222-502-ID001-ePower.network.2.MEAs.V

  OPC:/Eurotherm.ModbusServer.1/CLA_Gradateurs.192-168-1-222-502-ID001-ePower.network.2.MEAs.I

  OPC:/Eurotherm.ModbusServer.1/CLA_Gradateurs.192-168-1-222-502-ID001-ePower.network.2.MEAs.P

  ... Ditto for network 3 and 4

  I joined the part of the code that is dedicated for the reading of values, but it is not really helpful because I think that my method of reading is correct (data arrive but are never updated) is a 'lack' of command to request that the server acquires new data or a bug with the LV-iTools OPC server interface...

  For LabViewers advanced, I know that my attached code is not optimized and not the smartest, but keep cool, I do not need crazy performance

  Any suggestion?

  So, I was not on the spot for the tests, but now it's ok.

  Several series shares have been made to the walkthrough to the problem, but it's hard to know if all were beneficial:

  -An update of software Eurotherm: 7.50 to 7.68

  -An update of the firmware EPower: 3.01 to 3.03

  - and probably the main cause of the problem: change the cable through a cross-wired (we thought it was, but not in reality...). But even if it is the main cause: how it was possible to receive data by forcing the update in the OPC server... strange.

  Thanks for your help.

• Printable report query problem

  I try to develop a printable report query. I created a report under shared components query which consists of 12 separate queries that collect data are all related to a single page element. The intention is to create a PDF document that is printed to the user on demand that will display all this information on the page element they have chosen.
  
  The query of the report gathers information and generates an XML file in the following format.

  <DOCUMENT>
      <ROWSET1>
          <ROWSET1_ROW>
                           *Data from query 1*
          </ROWSET1_ROW>
      </ROWSET1>  
      <ROWSET2>
          <ROWSET2_ROW>
                            *Data from query 2*
          </ROWSET2_ROW>
          <ROWSET2_ROW>
                            * Data from query 2*
          </ROWSET2_ROW>
     </ROWSET2>
     <ROWSET3>
         <ROWSET3_ROW>
                            * Data from query 3*
         </ROWSET3_ROW>
         <ROWSET3_ROW>
                            * Data from query 3*
         </ROWSET3_ROW>
     </ROWSET3>
  ......
  </DOCUMENT>

  Then, I took this XML file and developed a model RTF using Office BI Publisher and imported as a layout of the report.
  I then connected this provision of the RTF to the report query and he ran. I don't have all the data to print.
  
  I found the reason why that it did not work, it is that the XML file that is generated by the report query is not static. The following XML file that was generated by the report query looked like this:

  <DOCUMENT>
      <ROWSET1>
          <ROWSET1_ROW>
                             * Data from query 3*
          </ROWSET1_ROW>
          <ROWSET1_ROW>
                             * Data from query 3*
          </ROWSET1_ROW>
      </ROWSET1>  
      <ROWSET2>
          <ROWSET2_ROW>
                             * Data from query 7*
          </ROWSET2_ROW>
          <ROWSET2_ROW>
                             * Data from query 7*
          </ROWSET2_ROW>
          <ROWSET2_ROW>
                             * Data from query 7*
          </ROWSET2_ROW>
     </ROWSET2>
     <ROWSET3>
         <ROWSET3_ROW>
                             * Data from query 1*
         </ROWSET3_ROW>
     </ROWSET3>
  ......
  </DOCUMENT>

  So I can't develop a RTF model to display the data, if I do not know where these data will appear in the generated XML.
  
  Questions (I'll offer several POINTS to anyone who can answer all of these questions!)
  
  I use APEX version 3.1
  
  * 1. Why the report query seems randomly to renumber and reorganize the XML it produces? *
  
  * 2. Is it possible to make the report query to display the XML data in the order in which the individual queries are classified each time? *
  
  * 3. Is it possible to designate exactly the lines of sets of lines or lines supported by APEX? *
  
  * 4. Are there other methods can I Explorer to produce this report? *
  
  * 5. Is it a problem because I'm on an older version? Is it not a problem on 4.1? *

  So, you have 12 separate petitions? No there is no way to join them in a union to build the required data set? Or even using views inline in a query for each set of values?

• Sort on dynamic query problem!

  Hello
  
  I have a dynamic query written in pl/sql, when I check "Sort" for each field in the report attribute, error message resurrected as "ORA-01785: ORDER BY item must include the number of an expression in the SELECT list.
  If I do not check sort, it works very well. In my applications, I need all the fields sorted by user, how do I solve this problem?
  
  My query as below:
  
  declare
  Ask varchar2 (2000): = "select";
  s_class varchar2 (1000);
  cursor c1 is select * from demo_preference;
  Start
  for c1_val looping c1
  If c1_val.login is not null then
  query: query = | » ' || 'login ' | ',';
  end if;
  If c1_val.id is not null then
  query: query = | » ' || 'id ' | ',';
  end if;
  .......
  end loop;
  query: = SUBSTR (query, 1, length (query)-1);
  
  s_class: = ' (NVL (: P2_class, "%" |)) ''null%'') = ''%'' || "zero percent" OR
  EXISTS (SELECT 1 FROM apex_collections WHERE collection_name = "P2CLASSCOL" AND class = c001))';
  
  query: query = | » ' || ' from ming.reg_report_view1 where '.
  || ' ' || s_class;
  Return (Query);
  end;

  Maybe the internal column used when you clicked the sort is not indicated in the report. Try to use aliases when you build the query string, it might help apex internally to identify a column even if its order is changed to another user. After all, the order of the columns in the code is dynamic and I assume that even the number of displayed columns can vary that could sort on a column that is identified by a number not valid.

  How about somewhere, displaying the report query so that you know what is the exact query processing, it could give you the best information on the problem.

  If the problem persists, use a collection that is extracted these record using the same query string, then replace the report to view the collection and then set the sort column on. This way Summit could get confused about which columns are being sorted and it would just sort on a c001... C050 column as if it were a string (Yes problems with the number of sort columns when you do this).

  If I run the query above is the length, but the problem is that I don't have team_id in the region table. How oracle to run this query. Please explain.

  Because of the determination of the scope.
  Oracle uses the "team_id" of the outer query.

  If you were to use:

  select * from team  where team_id in (select region.team_id from region);
  

  THEN, you will get an error.

• Insert query problem

  I have an insert query that I have not changed, but for some reason it won't insert anything in the database.

  The data is entered by a form of Ajax submission and goes to insert.php

  {if (isset($_POST['message_wall']))}
  / * The database connection * /.
  include ('config.php');
  
  / * Remove the HTML tag to prevent the injection of the query * /.
  $message = mysql_real_escape_string($_POST['message_wall']);
  $to = mysql_real_escape_string($_POST['profile_to']);
  
  $sql = "INSERT INTO wall (VALUES) (message)
  « '. $message. " »)';
  mysql_query ($SQL);

  I want to be able to add a user_id in the database too

  The ajax code:

  $(document) .ready (function () {}
  {$("form#submit_wall").submit (function ()}
  
  var message_wall is $('#message_wall').attr ('value');.
  
  $.ajax({)
  type: 'POST',
  URL: "insert.php"
  data: "message_wall ="+ message_wall, ".
  success: function() {}
  $("ul#wall").prepend ("< style li =' display: none" > "+ message_wall +"< /li > < br > < HR >");
  $("ul #wall li:first").fadeIn();)
  }
  });
  Returns false;
  });
  });

  Hello

  As it is a form ajax post then the form data should be inserted into your database using the insert.php script. All in the form of ajax jQuery is passed to the script of treatment if you process in the insert script it should work o/k.

  You must then include a text response to aid a statement simple echo in your insert script, this should include everything that you want to appear on your page.

  Php in your insert script would be similar to.

  At the beginning of the script.

  $date = $_POST ['msg_date'];

  At the bottom of the script.

  If {($success)
  echo "Inserted on $date ';
  } else {}
  echo "there was a problem processing your information.';
  }

  The jQuery to achieve code would be-

  Perform tasks of post-tabling
  function showResponse (responseText, statusText) {}
  $('.response').text (responseText);
  }

  More-

  success: showResponse,

  Treatment options in your ajax form

  And just include a

  where you want to display in your html code.

• cache of SQL query problem

  I'm seeing the log file to manage the sql query sessions in the responses. I see that if we run the same report multiple times, the sql query is displayed only the first time. Second time if I run it is not displayed. If I make a new report with diff columns selected, it gives me the sql code then. Where can I put this option to display the sql query whenever I run a report, even if it's the same report executed several times. Is this caching problem?

  It should not... You have disabled the "Cache" on the physical layer for this table? If you go to the Advanced tab, is the option "ignore the cache Oracle BI" checked?

• complex query problem

  I'm having some trouble with a request that I'm setting up for a page, I'll put up to show the candidates for the exam online their status in relation to a list of programs my Department offers online. What I'm trying to do is set up a query that will populate a table that displays a list of all the tests offered on the site and are active and then view the completion status of the user who is logged.
  
  Tests and user notes are all stored in a database, with tables like so (names changed for simplicity):
  program: list of trials by the title and the program number
  assessment: records of the responses of each user to a preliminary test survey
  review: documents answers, score and date of issue of a certificate of completion in transition from each user
  
  Of course, questioning each is a simple matter. Establishment of a join is a bit annoying, not only because of the eccentricities of ColdFusion. First of all, there is not a relationship of foreign key between these tables (I can't conceive this db, I just inherited it!). Secondly, not all entries in the table "programme" will exist in 'evaluation' or 'review' for the user logged on to this session. The difficulty I had in trying to join or make a query by query, that is I can get a list of everything a user has one entry for either or as well the assessment or examination. However, to obtain a result which a of the main AND this list is escape. At this point, I have a master list and status for about half of the results I need, but about half are not drawn in the query.
  
  I have attached the code I used to define the query and its implementation, in its latest version. This got me the closest to what I'm trying to meet up with (while all the documents that I read said a left outer join should not be able to work in the CF, I actually had good luck with that of related tables, that I read in the other pages). If I < cfoutput > without the group, I get duplicates for each instance of each program (including for users not logged) number, but only the result for the user of the session actually appears in the appropriate line. When grouped together, I think it's just to show the entrance to the first or the last finds it for all, rather than for the user of the session. I tried to do a query of this query to filter the results to anyone, but the user of the session, but the resulting records don't include those for which the user of the session has no entry. I can go on other ways that I attacked this problem and the results I've gotten if it will help nail down the problem.

  I managed to do work, it's the query I ended up with:

  
  SELECT *.
  OF qdprogram
  LEFT JOIN)
  SELECT useraccount, program_id, mark, Cert, CertDtd
  FROM useraccount WHERE = tblLearnerExam "#session.userid # ') test2
  ON qdprogram. QDProgramNumber = test2.program_id
  ORDER BY qdprogram. QDProgramNumber
  

  After a few attempts to make it work in the CF, I started tinkering with it in my db and managed to do the work. Thanks a lot for your help!

• A difficult dynamic SQL query problem

  Hi all
  
  I have a very interesting problem to work:
  
  We have this special table defined as follows:
  
  CREATE TABLE sales_data)
  sales_id NUMBER,
  NUMBER of sales_m01
  NUMBER of sales_m02
  NUMBER of sales_m03
  NUMBER of sales_m04
  NUMBER of sales_m05
  NUMBER of sales_m06
  NUMBER of sales_m07
  NUMBER of sales_m08
  NUMBER of sales_m09
  NUMBER of sales_m10
  NUMBER of sales_m11
  NUMBER of sales_m12
  sales_prior_yr NUMBER);
  /
  
  Columns ' sales_m01... sales_m12' represents aggregated monthly sales, what "sales_m01" is translated by "sales for the month of January, January is the first month,"sales_m02"in sales for the month of February and so on.»
  
  The problem I encounter is that we have a project that requires that a parameter is passed to a stored procedure that represents the number of months which is then used to create a SQL query with aggregations of next mandatory field, which depends on the parameter passed:
  
  Example 1: entry of parameter: 4
  Should be built dynamically to SQL query:
  
  SELECT
  Sum (sales_m04) as CURRENT_SALES,
  Sum (sales_m01 + sales_m02 + sales_m03 + sales_m04) SALES_YTD
  Of
  sales_data
  WHERE
  sales_id = '0599768';
  
  Example 2: input parameter: 8
  Should be built dynamically to SQL query:
  
  SELECT
  Sum (sales_m08) as CURRENT_SALES,
  SUM (sales_m01 + sales_m02 + sales_m03 + sales_m04 +)
  sales_m05 + sales_m06 + sales_m07 + sales_m08) SALES_YTD
  Of
  sales_data
  WHERE
  sales_id = '0599768';
  
  
  So in a sense, the contents of SUM(sales_m01...n) would vary according to the parameter, which must be a number between 1... 12 what is a month, which in turn corresponds to a range of real field on the table itself. The resulting dynamic query should include only those columns/fields in the table that is within the range given by the input parameter and does not account for all the other columns/fields.
  
  Any solution is greatly appreciated.
  
  Thank you.

  SQL> declare
    cols long;
    param integer := 6;
    sales_id integer := 0599768;
  begin
    for i in 1..param loop
      cols := cols || 'sales_m' || to_char(i, 'fm00') || '+';
    end loop;
  
    dbms_output.put_line('select sum(sales_m'||to_char(param,'fm00')||') current_sales, sum(' || rtrim(cols,'+') || ') sales_ytd from sales_data WHERE sales_id = :1');
  end;
  /
  select sum(sales_m06) current_sales, sum(sales_m01+sales_m02+sales_m03+sales_m04+sales_m05+sales_m06) sales_ytd from sales_data WHERE sales_id = :1
  PL/SQL procedure successfully completed.
  

  Now it should be obvious:
  Instead of dbms_output OPEN a refcursor:

  SQL> declare
    cols long;
    param integer := 6;
    sales_id integer := 0599768;
    cur sys_refcursor;
  begin
    for i in 1..param loop
      cols := cols || 'sales_m' || to_char(i, 'fm00') || ',';
    end loop;
  
    open cur for 'select sum(sales_m'||to_char(param,'fm00')||') current_sales, sum(' || rtrim(cols,',') || ') sales_ytd from sales_data WHERE sales_id = :1' using sales_id;
    .....
  end;

• Having a column name as a variable in a query, problem!

  I have a problem with a simple query below
  
  
  SELECT * FROM DisneyWHERE Upper (COLNAME) AS SUPERIOR ('%' |) SEARCHSTRING. '%'); SELECT * FROM Disney
  WHERE Upper (COLNAME) AS SUPERIOR ('%' |) SEARCHSTRING. '%');
  
  My problem, the variable of column name is not recognized as a column for example name
  A user can select to display a set of characters from the database by user name, movies, etc (they selecting this function since a combobox), they then enter a search string (textbox)
  column name = user name
  SearchString = pluto
  
  SELECT * FROM Disney
  WHERE Upper (COLNAME) AS SUPERIOR ('%' |) SEARCHSTRING. '%');
  
  The problem is orac; e does not seem to be picking up this column name is a column name and seems to be a simple comparison. To make this more clear
  
  It "seems to match the username = pluto
  instead of find pluto in the username column.
  
  Someone at - it ideas how I can get around this. I have a strange feeling, it's something to do with pl/sql dynamic, but I am new to oracle, so I have no idea of how to write dynamic queries. Any help would be appreciated muchly

  Sort of Yes and no.

  If colname is 'film' and the search string 'star wars' is the place where actually takes the clause...

  WHERE username as username
  AND the movie like 'star wars % % '.

  If username is not limited in any way and it limits just on film.

  Conversely if the column name is "username" and the search string is 'Bob Smith' then where clause evaluates actually to...

  WHERE username like ' %% of Bob Smith.

• query problem

  Happy Friday stock DB,.

  I have a compex query based on the table of pipeline and the view function. This query is bind to my report of the Apex.

  In Dev, the Apex report returns results in less than a second.

  In the Test, same Apex app, almost the same data, the Apex report return results more than a minute. But when I run the exact query behind the report in SQL Developer, it returns results in less than a second.

  This confused me! Anyone have any suggestions why my Apex report in test is slow?

  See you soon

  Before you repost read the FAQ to find out how to make an application for tuning and the info you provide

  Re: 3. how to improve the performance of my query? / My query is slow.

  1. the query

  2. the DDL for tables and indexes

  3. confirmation that the stats are up to date and the order allowing you to collect statistics

  4. information on the data in the tables: line total and account for different predicates used queries

  A common cause of poor performance is that the statistics are not updated. For your use case stats may be common in dev but not in test.
