• I'm reading the data (speed rate and flow) of a table and it plot in a graph.

  I'm reading the data (speed rate and flow) of a table and it plot in a graph. I need to draw two values of l/min (speed) to the same speed. How can I do using a loop for?

  There is no need actually to use a loop FOR this. And using a graphic waveform isn't the type of field for this, for a waveform you a (Start), the dT T0 (greatness not) and table D (Data), this isn't what you want unless you know precisely the measure will take place according to an orderly disposal, you'd want a xy chart so that you can trace the measures where they occur in the axes X and Y of preference.

  

• Read more data 1 byte of visa

  Hi, when I use VISA to read more data of 1 byte, only the first table got the data, but I want to separate data from 40-bit to 5 tables. Does someone know how to separate data in the tables? Thank you for the reply!

  Your problem is the ASCII conversion attempt.  As I said before, you have raw binary data.  Therefore do not touch anything that deals with ASCII.  All you have to do is take your byte array and convert each element in an array of Booleans.

  

• Read the data in the first column selected in a multicolumn listbox

  When a line is selected in a ListBox multicolumn (1 point), how can I go on reading the data in the first column?

  

  The listbox multicolumn itself is the digital picture data type. If you have allowed only 1 point selection and selection mode select any row, it returns the line number. The property node 'Element names' to return a table 2d-chains of the elements in your Inbox. The index of the row to the value of the listbox and column 0. See code attached.

• Loading XML into the relational Table data

  Hello

  I get a generated XML file to other tools (Windows), I am trying to create a Linux shell script that will gather the necessary XML file to my Linux server, then ask Oracle to use this file to load the XML data into a relational table. This activity and the data will be needed on an ongoing basis.

  I tried two ways. First, I loaded the XML document into the database and tried to extract the data directly from the document, but it does not work. Now I want to try to read the data directly from the file on the server through select, however I don't get all the returned data. In the Select statement below, I am trying to query the data to see what is returned for my tests.

  Create Table ci_results_table (transactionID Varchar2 (100), //transactionID should be PrimaryKey but became errors in test of insert, PK so deleted NULL value)

  message Varchar2 (200),

  This Varchar2 (50).

  XMLType of the ProcessedDate,

  status Varchar2 (50).

  sourceFile VarChar2 (100));

  Select x.*

  from XMLTable)

  ' TSPLoadResults/results '.

  PASSAGE xmltype (bfilename('CMDB_DEVADHOCRESULTS_DIR','LoadResults-HP_146.results.xml'), nls_charset_id ('AL32UTF8'))

  COLUMNS

  transactionID PATH Varchar2 (100) 'TransactionID '.

  Result XMLType PATH 'result ',.

  Message Varchar2 (200) PATH "Message."

  PrimaryKey Varchar2 (50) PATH "PrimaryKey"

  Date of ProcessedDate path "ProcessedDate."

  Status Varchar2 (50) PATH "Status."

  SourceFile VarChar2 (100) PATH "SourceFileName.

  ) x

  ;

  Eventually, I'll have to build on that to limit the returned data to records where SourceFileName is like '% PA' and insert what is returned in to the ci_results_table. Attached is an example of the XML results file I am trying to load, it is named "ResultsTransformedtoUnix" because I used dos2Unix to convert Unix which can be good or bad. (I send the output file must be converted to the format BACK until the other application can read). Original (before converting Unix) file named in the script is also attached.

  Help, please. Thank you!

  Hello

  I see some bad things in your query.

  (1) obvious one, explaining why you get all the data: there is a typing error in the XQuery expression, there 'result' not'slead.

  (2) ProcessedDate can be extracted as a date (at least not directly) because it actually represents a timestamp, use the TIMESTAMP WITH time ZONE HOURS and cast back to DATE data type in the SELECT clause

  (3) transactionID is an attribute, it must be accessible with ' @' (or ' attribute:' axis)

  (4) if the encoding of file really is ISO-8859-1 as suggested in the prologue, then do not use AL32UTF8 but the name of the corresponding character set: WE8ISO8859P1

  Here is the query to work:

  select x.transactionID
       , x.Message
       , x.Primarykey
       , cast(x.ProcessedDate as date) ProcessDate
       , x.Status
       , x.SourceFile
  from XMLTable(
         '/TSPLoadResults/Result'
         PASSING xmltype(bfilename('XML_DIR','LoadResults-HP_146.results.xml'), nls_charset_id('WE8ISO8859P1'))
         COLUMNS
           transactionID Varchar2(100)            PATH '@transactionID',
           Message       Varchar2(200)            PATH 'Message',
           PrimaryKey    Varchar2(50)             PATH 'PrimaryKey',
           ProcessedDate timestamp with time zone PATH 'ProcessedDate',
           Status        Varchar2(50)             PATH 'Status',
           SourceFile    VarChar2(100)            PATH 'SourceFileName'
       ) x
  ;
  

  Directly on the file using this query will only be decently (for large files) on 11.2.0.4 and beyond.

  On older versions, first load the file into a (temporary) XMLType column with binary XML storage and CHOOSE from there.

  because I used dos2Unix to convert Unix which can be good or bad.

  This conversion should not be necessary.

• How to read the data with different XML schemas within the unique connection?

  • I have Oracle database 11g
  • I access it via JDBC: Slim, version 11.2.0.3, same as xdb.
  • I have several tables, each has an XMLType column, all based on patterns.
  • There are three XML schemas different registered in the DB
  • Maybe I need to read the XML data in multiple tables.
  • If all the XMLTypes have the same XML schema, there is no problem,
  • If patterns are different, the second reading will throw BindXMLException.
  • If I reset the connection between the readings of the XMLType column with different schemas, it works.

  The question is: How can I configure the driver, or the connection to be able to read the data with different XML schemas without resetting the connection (which is expensive).

  Code to get data from XMLType is the implementation of case study:

   1   ResultSet resultSet = statement.executeQuery( sql ) ; 
   2   String result = null ; 
   3    while(resultSet.next()) { 
   4   SQLXML sqlxml = resultSet.getSQLXML(1) ; 
   5   result = sqlxml.getString() ; 
   6   sqlxml.free(); 
   7   } 
   8   resultSet.close(); 
   9    return result ; 
  

  It turns out, that I needed to serialize the XML on the server and read it as BLOB. Like this:

   1    final Statement statement = connection.createStatement() ;  2    final String sql = String.format("select xmlserialize(content xml_content_column as blob encoding 'UTF-8') from %s where key='%s'", table, key ) ;  3   ResultSet resultSet = statement.executeQuery( sql ) ;  4   String result = null ;  5    while(resultSet.next()) {  6   Blob blob = resultSet.getBlob( 1 );  7   InputStream inputStream = blob.getBinaryStream();  8   result = new Scanner( inputStream ).useDelimiter( "\\A" ).next();  9   inputStream.close(); 10   blob.free(); 11   } 12   resultSet.close(); 13   statement.close(); 14  15   System.out.println( result ); 16    return result ; 17
  

  Then it works. Still, can't get it work with XMLType in resultset. On the customer XML unwrapping explodes trying to pass to another XML schema. JDBC/XDB problem?

  Hello!
  Try something like that. Just one example.
  You will need to change the filename and tablename that you need.

  declare
  l_file  client_text_io.file_type;
  l_row   varchar2(100);
  l_count pls_integer := 0;
  
  begin
  l_file := client_text_io.fopen ( 'data.dat', 'R' );
  
  if
    NOT client_text_io.is_open ( l_file )
  then
    message ( 'File data.dat could not be found. Please check filename and path.' );
    return;
  end if;
  loop
    client_text_io.get_line ( l_file, l_row );
    insert into your_table ( data )
    values ( l_row );

• Satellite P500/01R reads the data, but cannot write data on CD files

  I recently bought a laptop Satellite P500/01R. I am able to read a data CD, but can't write data on CD files. The CD is read/write.

  Any ideas?

  Hello

  Have you tried different burning software?
  I m using Nero and in my opinion one of the apps better combustion.
  Here, I can choose between CD, DVD, DL or Blueray (only possible if the CD/DVD drive also supports this).

  Have you also checked diffΘrents CDs from different manufacturers?
  You should do this since not all disks are 100% compatible.
  I had several problems with different CD or DVD in most of the cases it was a compatibility issue, I tried TDK and this kind of drive is compatible with my CD/DVD drive
  I m using the standard of R.

• reads the data when I select run

  When I insist on running my program reads the data from the meter power... when I'm not it gives me an error. I tried to put right waiting them etc and nothing seems to be set. Also, when I take the vi that read data from the electricity meter, the code runs much faster. I don't know if this has to do with global variables or what, but I just change a code supplied with this unit and it included global variables. I tried not to play with those yet. Anyway, if someone sees something that would eventually cure this problem please let me know. Thank you.

  
  

• Tables and table data

  Hello-

  How is it when I create a node of a table property value and build a table of this node of property value, it gives me an annexed table?

  I tried indexing in this table twice for a single row of values, but when I try to compare the 1 index of this row in the table with the

  first index value from an array of the same size, the equal sign will not indent the table created index from the table. I see that the

  output wire is pink, which means that the value is considered as text... How can I convert that to a number so that I can compare the first value of a line

  in a table of the first value of a picture of a line to determine if they are equal? Array index is fed data points from

  a graph and once this 1st value of the array index is the first index value of the row in the table, I hope to have the index given in the table

  turns green when there is a football game. Thank you.

  Hello

  I'm not absolutely sure I knew you. Displaying a VI or a screenshot could be useful...

  However, attached, you will find a simple VI compare the first value of a table wanted the first value of a table row.

  Note that the table data type is string, not digital. No matter if you put numerical values in the table there are always string. A conversion is necessary to compare the values in array of numeric values.

  The values in the table are displayed as a 2D array in which the first dimension contains the lines (x).

  I hope I could help you with that.

• How to read the date of the day of the day of the year?

  I want to put 30 days for the test of endurance for the application of the components. the user will have the current value of 30 days with specify them the end of the day.

  I saw that the "seconds to Date/Time.vi" sure I checked the day of the year. If I can use this day of the year, I can add + 30 read 30 date.

  Barros,

  What I gave was the answer you were looking for originally because I believe.  You will not just be able to read the date in a coherent way and then add 30.  You can either use the function Get time in seconds or a few varaint it and then add the offset you want (you could use the get a Date/time string and enter the date directly, but this digital conversion which will be useful in the monitoring of the time elapsed will be much more difficult than what I provided only).  If you want to stop the test, simply to keep track of the amount of time the test is in pause and extension at the time where that amount.

• Reading large data using the database connectivity

  Hello

  I use the Labview database connectivity toolkit to connect to my database sqlitev3 (I'm using ODBC). I just have to connect to the database (using the block of open_connection) and read all the values inside (using the select_data block). The problem is that my database is huge (about 2 GB), and I get this error:

  .

  What should I do? It seems that he reads the data in the memory and it doesn't have enough space for it. When I read the data I want to write to a file.

  

  Read it in pieces. Write each piece to the file, and then repeat with the next segment. Try to read and process all data in one shot is not very practical and you found out will not work.
