• Writing data in the text file or excel spreadsheet

  Hello

  I have a silly question to ask questions about the writing of data in a text file or a spreadsheet. I have an example that simulates a sine-swept DAQmx. The output it provides is the (amplitude and phase) frequency response function that is plotted on a graph (see VI) attached. I like to use these data for further analysis by transmitting the data to a text file or a spreadsheet. I've tried a few things, but the thread is broken. I guess I use the sink badly - so I was wondering, can you please advise me on what sink should I use?

  Your help would be very appreciated,

  Thank you very much

  The wire is broken, because you cannot connect this type of data to one of these two functions. The data source type is a table 1 d of the clusters, where each cluster contains two tables. The text file write accepts strings, not clusters. Writing on a file action accepts dynamic data, and while you can convert dynamic data tables, there is no built-in mechanism to convert a table 1 d of the clusters of two matrices.

  What you need to do is to convert the data in a format which can be accepted by these functions. Since you want to have a "spreadsheet" file then you should use writing to the spreadsheet file that creates a delimited text file. Since the frequency data would be the same for the plot of the magnitude and phase diagrams, you can have 3 columns: frequency, amplitude, and phase. You can take off the items using Unbundle by name, and then create a table 2D of each element of the cluster. The real question is to know if you want to save the data at each iteration and if you simply add on the file. The attached figure shows write an initial header and then adding just streaming the data.

  What tool to spool the file well? Did he go any where near a GUI tool? I bet it was the precision on the data type or the type of incorrect data in total

  If I paste 20071113121100 into a new excel workbook, the display will return as 2.00711E + 13 - when I put a column data type number that I see all the numbers.
  OK it's not great, but you get what im saying:

• The monitoring of test data to write in the CSV file

  Hi, I'm new to Labview. I have a state machine in my front that runs a series of tests. Every time I update the lights on the Panel with the State. My question is, how is the best way to follow the test data my indicators are loaded with during the test, as well as at the end of the test I can group test data in a cluster, and send it to an another VI to write my CSV file. I already have a VI who writes the CSV file, but the problem is followed by data with my indicators. It would be nice if you could just the data stored in the indicators, but I realize there is no exit node =) any ideas on the best painless approach to this?

  Thank you, Rob

  Yes, that's exactly what typedef are to:

  Right-click on your control and select make typedef.

  A new window will open with only your control inside. You can register this control and then use it everywhere. When you modify the typedef, all controls of this type will change also.

  Basically, you create your own type as 'U8 numéric', 'boolean', or 'chain' except yours can be the 'cluster of all data on my front panel' type, "all the action my state machine can do," etc...

• Read data from the Table and load it into the csv file

  Hello

  I would like to read a table (select * from employees) and load the data into a csv file.

  What methods are available?

  Records will be at high volume.

  Thank you

  If it is to do a lot, use APEX.

  Create a new page with an interactive report based on the SQL code you want. When you go to download Excel, it is actually a CSV file.

  If it is large, you may need to go on the FILE_UTL road.

  If it is only once, use an interface such as SQL tool * or SQL * Developer.

  If it's a learning experience, you must do all three.

• faced with the question when writing data to a flat file with UTL_FILE.

  Hi gurus,
  
  We have a procedure that writes the data from the table to a flat file. RAC is implemented on this database.
  While writing data if the current instance, this procedure creates two copies of the data in parts.
  
  Any body can help me to solve this problem.
  
  Thanks in advance...

  I also asked this question, but it seems no final solution...

  In any case, here are two possibilities
  (1) the directory for the file among all nodes share
  (2) run you a procedure on a specific node

• There is a special token that I can put in a column of the CSV file recovery channel which implies approval of the current value?

  Versistand version is 2013 sp1.

  I use stimulus CSV expressions in my sequence in real time and want a channel to keep its value current (last) until a certain time. Is there a way to do this?

  Stimulation CSV file example:

  timestamp, chan1, chan2

  0,0,

  10, 1,

  20,1,5

  30,2,10

  In this example, chan2 would retain its current value until the timestamp 20.

  Is it possible to implement this feature?

  Kind regards

  Rick Howard

  Thank you! It is a valuable feedback. I can't think of a way to do natively with the functionality of reading CSV for sequences in real time. Some thoughts on how this can be done:

  1. create your own utility to sequences of script based on a CSV file in real-time. Extend the functionality of having a special marker in a cell which designates not only to change the value for the channel as timestep. Do not start from scratch. This tool open source and this one the two script of sequences in real time and stimulation of reading profiles based on data sets (although in different ways).

  2. with the help of software without insertion to the fault of the string value that you want to keep the initial value for the first X seconds of reading the CSV file. For example, you could play another sequence with your CSV file at fault the channel at its current value so that reading CSV does not replace the value.

  Use the worksheet in reading file.  You can then use the table to Index to get the first colum and search for an empty string.  This will give you the break between the header data and the actual data.  Take all the data after this line and convert it to a number (String number floating/Exp).

  Hi Jetfire,

• list box given to the .csv file using write on the worksheet File.vi

  Hi, I use the write on the worksheet File.vi to write data multicolumn ListBox to the .csv file. If I do record from Excel, the pop-up window shows as an attachment. And data listbox are too different.  I want the data displayed in the first line not the second row (third photo).

  Thank you for your help.

  Before making your Save As in Excel, change the cell formatting of number. This should avoid the scientific notation conversion before you re-register.

  Or just use Notepad to display the file instead of Excel.

• ADF: How to manage the value zero when downloading the csv file

  Dear all,

  I'm new in the ADF and use 12.2.1. I am downloading of data in the database using af table: inputfile and CSVParser class. Data download correctly in the database where all columns are met, but whenever the csv file has value null (empty) in his column, then CSVParser class does not recognize it and get the next value of columns and assign the previous column. I also tried another one that uses a different class to download date but not get success.

  For Ex:

  ID name Dept

  1 abc Dept1

  2 cde Dept2

  3 Dept3

  In example above two first line are perfectly inserted in the table while the third line Id goes to ID column, due to the value of the column name is null class CSVParser does not recognize it and put Dept3 in the name column.

  Please help how to handle this.

  Thanks in advance.

  Kind regards

• How to download the Csv file with column headers

  Hi all

  This is pavan, using Apex version 4.2.3

  
  

  I am trying to download the csv file I followed this link , and I'm able to download excel with headers, when I try to download with headers of this error "'ORA-01858: a non-digit character was found here where was waiting for a digital" I searched in google but could not find the right solution, "

  
  

  can anyone help on this please.

  Thanks in advance,

  This article is 6 years old.

  You should study the solutions that are available for APEX 4.2: data loader or the 'Excel2Collection' plugin (which also manages the CSV files).

  Data Loader

  It is a wizard that generates an Assistant for your application.

  Excel2Collection

  You will use the Excel2Collection (in a single process) to convert the BLOB in a Collection

  Then, in a 2nd address), you just do a "INSERT...". SELECT statement.  Add ' where seq_id > 1 "for files with a header.
