• What is the right way to use variables controlled by the two buttons and programming?

  First of all, I apologize if this has been discussed before.  I know not how to phrase succinctly the application, so maybe I just missed the search terms.

  We have several pieces of the Labview software in the laboratory that automatically control things like the taps and heaters.  Sometimes we also manually control these same things.  I'm moving old NI PCI (and older versions of Labview) maps to a variable and based on compactRIO system shared network.  However, I'm still not on best practices to achieve.  I need to be able to have a script running at any time control panel so that I can access, for example, a valve controller (which is just a Boolean), and I need power open and close the valve by programming other scripts.  I need, of course, the control panel to track the State of the valve until it opens another script, the Panel indicates that it is open, and the next push on the control panel it will close.

  Historically, this has been processed using structures business to move from a "computer control" and "hands-on" with global variables that define the State of the valves.  Of course, this is not recommended.

  So far, I've played with the help of two variables, a status of valve and the other for the State of button.  The Panel configuration then loops, reads the status of the valve and puts the State of button if the State of the valve has changed.  I can do this with registers at offset or with the structures of the event, but anyway, it gets very crowded and seems inefficient.  Is there a good way to do this in Labview?  It seems this is a common problem, so I hope there is an easy and elegant solution that I've missed.

  Variable published use shared network.  Your scenario and your manual of the interface and change the variable and then shared your cRIO reads fair value and writes the appropriate values.

  Now for a cool part.  On your manual interface, right-click on your heart control that you want to use to control the shared variable and go to properties.  There should be a data binding tab in the Properties dialog box.  You can bind a control/indicator to a published network shared variable.  So this button will always be attributed to the current state.

  Your script should just read the shared variable before resuming to verify that it is in the correct state.

• Can I use the session with the presentation variable variable

  Hello

  I'm using a method join the variable session or repository with the presentation variable.

  I created a variable called 'VarPres' in obiee presentation I created a session with a new block of initialization variable and I made this request

  "{Select fullName from employees where idEmp=@{VarPres}.

  but when I called the session variable in obiee I got this error

  The session variable, NQ_SESSION. S_OBJ, has no definition of value

  Hello

  Does not allow a presentation in an init block variable, simply because there is no variable presentation.

  In general what you try to do probably will never work because of "timing" and is as a session variable.

  A session variable is set once per session, for once he put no exchange of value as the init block is not executed again. So, because of this you already can imagine that there is a problem in your logic, if you want to use a value set by the user in the front end to set the value of a session variable.

• Default presentation variable used in the SQL filter expression

  Hello
  I am trying to use a default value for a variable used in a sql expression in a filter presentation and could use assistance on why obiee stifles the syntax.
  
  I have a report prompted with a prompt on the name of the month (variable presentation framework - pres_month_name). The value read is used in a filter as an sql expression. The sql expression is a DEAL on the variable of presentation and its conversion to a number based on business rules.
  
  In the sql expression, I give you the presentation variable a default value for a variable of repository - rep_default_month_name. Repository variable is correct and no, based on business rules, returns an appropriate default month name.
  
  Now, if I hard code the value by default, there is no problem. Here is a sample of the filter:
  The month number less than or equal to * DEAL "{pres_month_name} {OCT}" WHEN "NOV" THEN 10 WHEN... END *.
  
  Notice that the variable of presentation is between single quotes, because this is an area of character. Once more, it works fine, but I don't want to hardcode the default, I want it based on the variable repository, therefore:
  
  The month number less than or equal to * DEAL '{pres_month_name} {ValueOf (rep_default_month_name)}' WHEN 'NOV' THEN 10 WHEN... END *.
  
  By having this syntax for default of the variable of the presentation, I receive a message from the incorrect values in a filter.
  
  This report is not only used on a dashboard, but used in a briefing book as well. Whenever a briefing book is updated, by default the presentation variable is used, because obviously, the presentation is not available in a briefing, and I don't want to use a hard-coded value.
  
  I could duplicate the report and adjust the sql to not use the presentation variable, but always use the repository variable that returns a month by default, but I would be duplication of effort and I have to do this on several requests.
  
  Thanks for the help!

  Try this syntax described in the blog of Shiva that follows...

• Column unresolved when using presentation variable in the filter responses

  Hi all
  
  I am using a dashboard command prompt that sets a variable presentation - pres_year. I use the presentation variable in the filter of the application.
  In the 'Criteria' tab, in the filter for a request, I put a year column (YEAR) the presentation via the Expr Variable variable and enter the variable name of presentation only. End up with:
  YEAR is equal to / is in @{pres_year}
  
  When you use the dashboard, the prompt and ask all work fine. The problem is when I'm in demand for answers and I click on the "View results" button I get the following error:
  "NQSError: 27005 unresolved column pres_year'.
  
  Any suggestions?
  
  Thank you.

  Set a default value after the presentation variable in your filter. If you put no default value, and then in the responses, the application not of value to the variable of presentation. Click on the filter and add default value. Then it won't work.

• In the presentation variable date format

  Dear Guru,
  
  My guest has a calendar month edit box that is in the format "YYYY / MM". I put this as a variable presentation p_month.
  
  Now, I need to add 1 month to this presentation variable in the filter, I tried to write the sql code but it's complicated, and it does not work. Could someone help?
  
  Thank you very much
  Joe

  An approach more:

  using filter based on another request...

  create a query containing the following columns... (Assuming that YYYY / MM column is: A).

  Min (A)

  "and keep the filter on A > ' @{p_month}"
  Save this report with a name: RapportB

  Your main report on A filter should be like this:

  filter on a column > advanced > filter based on another request, now browse the RapportB and then to specify the unique column present in this report to be filtered...

  hope you understand this approach...

• Date show invites by using the calendar and presentation Variables

  Hi all
  
  That's what it takes...
  
  I need to create a two prompts (from_date and to_date) on a date column so that I can filter the data by using a condition. This is how I do
  
  I created two guests (edited the formula) and passing values to two variables var_from and var_to presentation. In the report, I limit the query on assistance between motor coaches for both the presentation variable. Everything works fine but the problem is I need display var_from and var_to in my report also.
  
  I'm referencing variables like ' @{var_from}' and ' @{var_to}' but I get two columns as white. I don't really know why I get empty values for these two columns only when I am able to filter my report with success on the basis of the date values in the guests...
  
  Just to metion... in my database, I have values in m/d/yyyy format only. So I am able to use the calendar successfully
  
  Any help on this would be much appreciated...
  
  
  Thank you
  -Ronny

  Ronny,
  Drafts of answers do you see? ID wait, but on the dashboard when you set filters, you should see values that crosses?
  You can extend the syntax of the variable closely and provide a default value, so when you work in the answers you can see what it looks like,

  something like @{var_from} {January 1, 2010 ""}

  Also you can reference variables in the title, the subtitle or the narrative views if you want.

• Looking for a better style or a way to write the INSERT statement, possible with brand of continuation

  Honestly, I really looked everywhere for this.

  The problem is that, while tinkering in SQL Developer and knowing that in the spreadsheet I can just execute individual instructions by placing the cursor on the SQL statement I want to run I tried to do an INSERT query that would allow me to run an INSERT statement for... Well many inserts.

  I thought I could use a brand of continuation but nothing I've tried has worked.

  INSERT INTO

  HF_easy_drinks

  VALUES

  ("Blackthorn", "tonic water", 1.5, 1.0, "pineapple juice", "mix with ice").

  ("Blue Moon", "soda", 1.5 "Blueberry Juice",. 75, "mix with ice, strain")

  ;

  
  

  I ended up doing just individual INSERT statements, which was not as convenient.

  INSERT INTO HF_easy_drinks

  VALUES ('Blackthorn', 'tonic water', 1.5, 1.0, "pineapple juice", "mix with ice");

  INSERT INTO HF_easy_drinks

  VALUES ('Blue Moon', 'soda', 1.5, 'Blueberry Juice',. 75, "mix with ice");

  Hello

  Perhaps you might prefer "an" insert like this:

  INSERT INTO hf_easy_drinks (x, y, z,...)
  SELECT "Blackthorn", "tonic water", 1.5, 1.0, "pineapple juice", "mix with ice" OF THE double
  UNION ALL SELECT 'Blue Moon', 'soda', 1.5, 'Blueberry Juice',. 75, "mix with ice, strain ' FROM dual
  SELECT UNION ALL... OF the double
  SELECT UNION ALL... OF the double
  ;

• Table query result using prepared as a parameter in the prepared statement later

  Hi all

  Very new to PHP. A series of 3 prepared statements (see code below), I'm trying to sink.  This page is triggered from a link on a page that lists the individual and all candidates which works well.  Prepared statement 1 works and displays the data in the columns line wanted specific, bottom access so I would call it record and areas, but I think it is called line and columns here.  Prepared Statement 2 which hands on a table of cross references (we have a many-to-many relationship between candidates and positions, therefore for the table of cross references) works and I can say the $selected_positions charges table, because I can see position_id data in the < body > of the file using this:

  <? PHP

  foreach ($selected_positions as $item) {}

  echo $item. "< br / > ';

  }

  ? >

  Can't take this $selected_positions table and use it as parameter in the prepared statement 3, at least not how I try to do.  So obviously he manages not prepared statement 3 no way is a table that I called $the_positions which is supposed to contain the ID of the post, position of securities and to position the position_id numbers that are in the array $selected_positions.  I can say that 3 of prepared statement is a failure because there is no indication in this table that is in the < body > of the file:

  < table class = "stripes table" >

  < b >

  Identification of the Position < /th > < th >

  < /Th > < th > post number

  Title < th > < /th >

  < /tr >

  <? PHP while ($stmt-> fetch()) {? >}

  < b >

  < td > <? = $position_id;? > < table >

  < td > <? = $position_number;? > < table >

  < td > <? = $title;? > < table >

  < /tr >

  <? PHP}? >

  < /table >

  Here is the PHP script:

  <? PHP

  require_once '... /includes/session_timeout_db.php';

  <? PHP

  require_once '... /includes/Connection.php';

  initialize the flag

  $OK = false;

  $sql = ' SELECT candidate_id, last_name, first_name, society, mas_number, last_modified, notes

  CANDIDATES WHERE candidate_id =?'; }

  If ($stmt-> {prepared ($sql))}

  $stmt-> bind_param ('i', $_GET ['candidate_id']);

  run the query and fetch the result

  $OK = $stmt-> execute();

  bind the results to variables

  $stmt-> bind_result ($candidate_id, $last_name, $first_name, $company, $mas_number, $last_modified, $notes);

  $stmt-> fetch();

  free resources for the second query database

  $stmt-> free_result();

  }

  get the associated positions candidate

  $sql = 'SELECT position_id FROM pos2cands WHERE candidate_id =?';

  If ($stmt-> {prepared ($sql))}

  bind the query parameter

  $stmt-> bind_param ('i', $_GET ['candidate_id']);

  run the query and fetch the result

  $OK = $stmt-> execute();

  Browse the results to store in a table

  $selected_positions = [];

  }

  find data on the position of the table

  $sql = ' SELECT position_id, position_number, title

  FROM place WHERE position_id =?';

  If ($stmt-> {prepared ($sql))}

  bind the query parameter

  $stmt-> bind_param ('i', $_GET [$position_id]);

  run the query and fetch the result

  Thank you in advancel

  You want to use the value of request 1 or query2 as a parameter in the query 3, right? Rather than build a table, you can simply use the value returned by each line that the query returns. I use PDO, no MySQLi, so I can't knock out quickly the MySQLi example for you.

  While ($result = $sql-> fetch (PDP::FETCH_ASSOC)) {}
  $field = $result ['domain'];

  Now we can use the value of $field as parameter for the next query.

  The brace that closes the while loop is placed after the last query

  so no need to fill an array with values

  }

  Your approach is doable with a few changes to the way in which you go through the table, but it is unnecessarily complicated.

  You might be able to use a single query to get all the data if you use left joins. With this approach, you start with the table that SHOULD return a result or which requires no dependencies to other tables. The structure is like this:

  SELECT field1, Field2, field3 FROM (SELECT * FROM table1 WHERE field3 = param1) has

  LEFT JOIN (SELECT * FROM table2 WHERE A.field4 = table2.field4) B

  LEFT JOIN table3 ON table3.field5 = B.field5 ORDER BY Field1

  A and B above are aliases for subsets of the table. You can image a (tacit) sign = equal A
