• How to use the global variable in the table target?

  Hello

  I am trying to load several files into a single interface. the data is loaded successfully. 92. the files are there. for this I used variables and package.

  My requrement is 92 files of data loaded into the target table. I want to know what data from file.

  to this I added a column (filename) to the existing target table.

  If I used joints (not same condition), its totally wrong. all file names are coming.

  Please see the following screenshots.

  

  exit; target table.

  

  in fact in the target table. first 10 lines are coming from file.i.e first _ACCOUNT_LIMIT_511.TXT. but all the files names are coming.

  I'm confuse. After the first data file inserted then insert second data file. in that all file names are coming. Please help me.

  I thought that the global variable is preferable to identify the data came from which file.

  to do this, the global variable is used in the target table. I don't always have my exit.

  Please help me.

  Thanks in advance.

  

  Hello

  You can use the same way, how you use the project variable, just you have to do a thin is #GLOBAL.variable_name for example: #GLOBAL. SMART_AL_FILE_NAME_S

  Note: Make sure you that while you use one variable overall in interface, indicator should be staged as you chose above the screen

  hope this helps you

• How to use the shared variables to address several Watlow controllers on the same COM port

  Hello

  I am using LabVIEW 2010 to control 4 Watlow temperature controllers on a port com 3 are model 96 and 1 is a zone EZ controller. The controller has a unique modbus address and I'm trying to read from and write in the individual records (for example, setpoint closed-loop) variable shared help. I would return the data during playback (even if the data is displayed as invalid), but I am unable to change the value in the registry in writing. How can I be sure that's the Modbus server send commands to the correct controller?

  Chuck

  Hi Chuck,

  Sorry for the delay in response, I was away last week. You can create as many servers for Modbus on one COM port that you would like, the only problem you'd see is if you tried to call the port from different locations at the same time. With respect to the documentation to cross, I'd start with the tutorial below for a comprehensive manual of Modbus. There are also quite a few listed under Datalogging and supervisory control Module help topics that may be useful if you want to solve specific issues.

• How to use the class IIA for LabVIEW driver wrappers?

  Hi all

  I've read some texts on IVI compliance, but I have not quite how I wrap an IVI - COM to an IVI - C. Where is this done?

  In MAX, I see:

  -Configuration-> software-> IVI Compliance Package 3.3

  But no properties in there...

  I have an analizer spectrum available drivers are only IVI - COM, but I want to wrap them up in IVI - C...

  can someone tell me step by step how can I do this?

  or maybe tell me some beginner tutorial?

  Kind regards

  JPLO

  Hello JPLO,

  Before trying to communicate with your instrument using any sort of instrument drivers, you must confirm that you can connect at a lower level.  In most cases, this means through VISA, using MAX.  IVI - COM driver installation program should add a software module to the IVI Configuration, which is the MAX.  Most installers IVI - C also adds a pilot session, but you'll need to create a.

  We include adaptors IVI - COM for class IVI - C with PKI pilots.  Here's a knockout who talk about them: IVI-C class for specific drivers IVI-COM driver Support

  You can also simply treat the IVI - COM driver like any other ActiveX object.

  What type of instrument you are using?

  See you soon,.

• If the Environment Variable in Vista

  How to change the Environment Variable in Vista? ... I could do with XP using Control Panel > performance and Maintenance, but could not find the area revealing in Vista.

  Hello

  When you see something surrounded of % this means there is a system environment Variable
  together who will take the place of it. SystemRoot where Windows so for most, it will be
  C:\Windows however if Windows is on drive D: it would be usually be D:\Windows.

  Start - type in the search box-> explorer.exe SystemRoot

  Enter and see where it leads you.

  Another is %UserProfile%, which is the currently logged-on user

  Start - type in the search box-> explorer.exe %USERPROFILE%

  Enter and see where it leads you.

  With the help of people and other environment variables, commands can be written so that they will apply no.
  matter where Windows to installed or that the user connects (for the above examples).

  To view the current system Environment Variables:

  Start - type in the search-> CMD box find top - make a right click on - RUN AS ADMIN

  When the COMMAND PROMPT opens it will look something like

  C:\Windows\System32 >

  Type SET and press on enter and you will see the present commands.

  to see the command SET type in ALL of the structure? and press on enter – the space between T and.

• Using an environment variable in a shortcut on the desktop

  I would like to create a shortcut on the desktop that uses part of the environment variable in the "Target" text box  I need to do this because the location of the program may vary from one site to the other.  I would like to be able to type the following:

  (\BestPractices\BP.mdb Y:\[MID(%HomeShare%,29,7)]

  HomeShare is an environment variable.  But the name of the folder is the 7 characters starting at position 29.  I would like to avoid having to do this in a batch file or other external utility.

  Thank you

  Well, no, it won't work.  Why not set up the database using the Runtime to create its own folder? --

• using the function - how to use the values of the input variables on the table select statement names

  Hello community, I have a problem when creating a function. The purpose of this function is to check the table of weather gave yesterday or not. We must check this on different tables on different sachems. We are creating a function with input variables.

  CREATE OR REPLACE FUNCTION IN_SCHEMA.IS_YDAYDATA_TO_TABLE

  in_tablename IN VARCHAR2,

  in_datefield IN VARCHAR2,

  THEN 1

  END;

  When creating, I got error: [error] ORA-00942 (44:19): PL/SQL: ORA-00942: table or view does not exist

  How to use the values of the input variables on the table select statement names?

  Hello

  Here's a way you can use dynamic SQL statements for this task:

  CREATE OR REPLACE FUNCTION IS_YDAYDATA_TO_TABLE

  (

  in_schema IN VARCHAR2,

  in_tablename IN VARCHAR2,

  in_datefield IN VARCHAR2,

  in_first_date DATE DEFAULT SYSDATE - 1,.

  in_last_date DATE by DEFAULT NULL

  )

  RETURNS INTEGER

  AS

  -IS_YDAYDATA_TO_TABLE returns 1 if in_schema.in_tablename.in_datefield

  -contains all the dates in the in_first_date of the range through included in_last_date

  - and it returns 0 if there is no such lines.

  -If in_last_date is omitted, the search only the data on in_first_date.

  -If in_first_date is omitted, it defaults to yesterday.

  -Time parts of the in_first_date and in_last_date are ignored.

  -Declaring variables

  sql_txt VARCHAR2 (1000);

  v_is_true INTEGER.

  BEGIN

  sql_txt: = 'SELECT COUNT (*).

  || 'FROM ' | in_schema | '.' || in_tablename

  || 'WHERE ' | in_datefield | ' > =: d1'

  || «AND» | in_datefield | '< >

  || 'AND ROWNUM = 1';

  dbms_output.put_line (sql_txt |) '= sql_txt in IS_YDAYDATA_TO_TABLE");  -For debugging

  Sql_txt EXECUTE IMMEDIATE

  IN v_is_true

  With the HELP of TRUNC (in_first_date) - d1

  TRUNC (NVL (in_last_date

  in_first_date

  )

  ) + 1                -- d2

  ;

  RETURN v_is_true;

  END is_ydaydata_to_table;

  /

  DISPLAY ERRORS

  If you must use dynamic SQL statements, put all the SQL statement in a single string variable, such as sql_txt in the example above.  In this way, you can easily see exactly what will be executed.  Comment out the call to dbms_output under test is completed.

  Try to write functions that will address not only the question that you have now, but similar questions that you may have in the future.  For example, now that interest you only to the verification of the data of yesterday, but later, you might want to check another day or range of days.  The above function combines the convenience of a function simple (looks like yesterday data if you don't tell him otherwise) with the power of a more complex function (you can use the same function to check any day or range of days).

• How to swap two values without using the third variable using the procedure

  How to exchange the two values without using the third variable using the procedure?
  
  In a procedure using two mode we pass two values A = x and B = y, and let us pass parameters to receive the output has A = y and B = x without using the third variable
  
  Published by: Millar on August 19, 2012 11:23

  Your question doesn't seem wise. As written, there is no reason to a third variable, just

  CREATE OR REPLACE PROCEDURE(
    x IN number,
    y IN number,
    a OUT number,
    b OUT number
  )
  AS
  BEGIN
    a := y;
    b := x;
  END;
  

  If it's an interview question, I suspect that the intention was that you had two settings IN OUT and you wanted to swap the values without the help of a third variable.

• How to use the functions of SetValue executeScript activity.

  Hello

  Could someone let me know how to use the function activity setValue (serialize concate, count etc) in activity executeScript. What all liberaries I need to import to executeScript. I want to perform the same task in executeScript performed in the setValue activity.

  Concerning

  Sunil Gupta

  Forgive me if I seem obtuse, but why would you use XPath functions (is that serialize, concat, and count) when there are perfectly good Java alternatives that will be much easier to use.  Java is, after all, the language used in the executeScript.  Serialize is just toString(), CONCATENATE is just + or. concat() (I assume that you are running on Java 6 web application server).  The count function is just the length() or size() methods or to the tables, the length property.  If you really need to reorganize in a variable of the XML data using a XSL stylesheet - you have access to all the functions in XPath 1.0 and XPath 1.0 power and you do not need to tinker with the headache of trying to debug Java in an environment (Workbench), which does not give you the tools that you would normally , as a contextual Editor.
