• How to get data from an Excel file exist using report generation tools

  I try to use the Excel vi get the data of the report generation tool, but I can't understand how to activate a path can be explored in the right type for the VI.  I tried to use the new Report.vi, but this does not work unless you use a template.  It will not open an existing excel file and make an open report to extract data from.

  Essentially, I have a bunch of excel files that have data in them, and I want a VI allows to analyze the data.  I'm going to pull in all the data directly from the excel file so I don't have to reproscess them all in text so I can use the more standard datasheet live but to convert even the excel file programtically in labview I still need to be able to open the excel file and get the data?

  I found my problem.  It turns out that only not to have had a problem with the tool box new report vi.  I had accidentally wired an input control of path of folder instead of an input control of path of file to it.  Changing the file type took care of her and I was able to access excel files, I tried using the new report VI to extract the file, and Excel Get Data to extract the data.

• Reading the data from an Excel file

  Hello

  I try to use the attached VI (adapted from an example provided by someone else in a different thread) to read an Excel file.

  It works well, aside from the fact that it leaves the file and Excel opened when it has finished running.

  How do I close the file (and Excel) by programming?

  Thank you very much

• VI data on average compared to the data from the Excel file on average .lvm

  I am trying to build a .VI to measure voltages on a channel of a transducer of pressure for a period of 3 minutes.  I would like the .VI to write all the samples of blood to a file .lvm with another .lvm file that comes from the average voltage over the period of 3 minutes.  I built a .VI making everything above so I think that... The problem I'm running into is when I opened the file .lvm of all samples of blood in MS Excel and take the average of them using the built-in Excel function (= AVERAGE(B23:B5022) for example) averaged and compare it to the .lvm file, which has just 3 minute average .VI voltage, they do not correspond to the top.

  This makes me wonder if I use VI with an average of function correctly or if maybe VI averages data different voltage than what is written in the .lvm file.

  Does anyone know why the two averages are different and how I can match.

  I have attached a picture of my functional schema with the file .VI for clarity.

  The Type of dynamic data of LabVIEW you use is a special data type that can take many forms.  It therefore requires the use "Of DDT" and "DDT" for the conbert to and from other data types.  These special conversion functions can be configured by double-clicking them and specifying the format you are converting from.  You can find the functions on the pallet handling Express-Signal.

  I've attached a screenshot of the modification of the code using the "DDT" and the average is very good.

  Please mark this as accepted such solution and/or give Kudos if it works for you.  We appreciate the sides for our answers.

• How can I export data from table to file

  Is probably a stupid question, but I have not found any KM to read a SQL server table and load its files into a text file.
  Could someone explain to me how can I do?
  Thank you

  You can use the ODISQLUnload tool. This will extract all the data in a file with the format specified in the tool.
  -in fact, if there is a large volume, I would be tempted to use a bcp command to do so. This could be in a procedure. You could get the bcp command format and a few hints on how to make generic km here

• Export data from the database to excel file using the procedure

  Hello
  
  I need to export data from database to oracle 10 g for the excel file, I try this code:
  
  First, I create directory to the user sys and give permition to user that I'm working on it

  create or replace directory PALPROV_REPORTS as 'c:\temp';
  
  grant read, write on directory PALPROV_REPORTS to user12 ;

  then I run this code

  declare
      output utl_file.file_type;
  begin
      output := utl_file.fopen( 'user12' , 'emp1.slk', 'w',32000 );
      utl_file.put_line(output, 'line one: some text');
      utl_file.fclose( output );
  end;

  the problem appears as
  ORA-29280: invalid path ORA-06512: at "SYS." UTL_FILE", line 29 ORA-06512: at"SYS." UTL_FILE", line 448 ORA-06512: at line 4
  
  Notice that I use the operating system windows as a client and a linux as a server database

  The file will be written to the database server or your GNU / linux and I'm quite sure, there is no folder named "c:\temp" on linux. It will probably be ' / tmp' on a unix server.

  And open the file, you must give the name logic directory 'PALPROV_REPORTS' it instead of the user name "utilisateur12".

• When I export the report to EXCEL files and filter the data, it will display incorrect data

  Hi experts,
  In OBIEE 11.1.1.6, when I export the report to EXCEL file and open this file to view all the data, it is correct.
  However, as the amount of data is so, so I add filter for each column (click on the sorting-> filter filter)
  When I select data in the filters, I'm afraid that I find the value of 'White' in the last line in the filter area, but in the table, there no null data. Why? Are you facing the same issue?
  Secondly, when I select a value, it will generate a data line.
  
  For example:
  2008 - Region1
  -The region.2
  -Elle3
  2009 - Region1
  -The region.2
  -Elle3
  
  
  When I select 2008 data in EXCEL, it will display unexpected data, as below:
  2008 - Region1

  Exactly... If you export to the format you will not face question of null data or incorrect when filtered.

  Kind regards

• export data from the table in xml files

  Hello
  
  This thread to get your opinion on how export data tables in a file xml containing the data and another (xsd) that contains a structure of the table.
  For example, I have a datamart with 3 dimensions and a fact table. The idea is to have an xml file with data from the fact table, a file xsd with the structure of the fact table, an xml file that contains the data of the 3 dimensions and an xsd file that contains the definition of all the 3 dimensions. So a xml file fact table, a single file xml combining all of the dimension, the fact table in the file a xsd and an xsd file combining all of the dimension.
  
  I never have an idea on how to do it, but I would like to have for your advise on how you would.
  
  Thank you in advance.

  You are more or less in the same situation as me, I guess, about the "ORA-01426 digital infinity. I tried to export through UTL_FILE, content of the relational table with 998 columns. You get very quickly in this case in these ORA-errors, even if you work with solutions CLOB, while trying to concatinate the column into a CSV string data. Oracle has the nasty habbit in some of its packages / code to "assume" intelligent solutions and converts data types implicitly temporarily while trying to concatinate these data in the column to 1 string.

  The second part in the Kingdom of PL/SQL, it is he's trying to put everything in a buffer, which has a maximum of 65 k or 32 k, so break things up. In the end I just solved it via see all as a BLOB and writing to file as such. I'm guessing that the ORA-error is related to these problems of conversion/datatype buffer / implicit in the official packages of Oracle DBMS.

  Fun here is that this table 998 column came from XML source (aka "how SOA can make things very complicated and non-performing"). I have now 2 different solutions 'write data to CSV' in my packages, I use this situation to 998 column (but no idea if ever I get this performance, for example, using table collections in this scenario will explode the PGA in this case). The only solution that would work in my case is a better physical design of the environment, but currently I wonder not, engaged, as an architect so do not have a position to impose it.

• Export data from the database Table in the CSV file with OWB mapping

  Hello
  
  is it possible to export data from a database table in a CSV with an owb mapping. I think that it should be possible, but I didn't yet. Then someone can give me some tips how to handle this? Someone has a good article on the internet or a book where such a problem is described.
  
  Thank you

• Save the data to the excel file

  Hello

  I make a program reads the value of the probe via serial port... but I don't know how I can record this data in excel file... I open the example in the labview example, but I don't want to like this... becaue I use a while loop in my program that cause opened "multi" excel file... . How can I solve this problem?

  You need to think about what you want to do, not how you want to do.  I'll make a few assumptions here - adopt to your notebook loads "real."

  I guess you want to take a series of readings from a device (sensor, serial port).  I suppose you take multiple readings, perhaps their display on a table or chart, for a certain period of time.  Once you have a set of data, you want to save all the data in an Excel file.

  If this scenario is correct, there are three distinct phases to this task - implemented the data collection (open the serial port, manage the interactions of the user according to the needs), data collection (and potentially produce tables or graphs) and save the data.  Note that only step 2, collect data, involves a repetitive action appropriate for a while loop.  Once you have all the data, you can then open an Excel report, use something like Excel table easy to put the Table in the report or chart Excel easy to put a chart in the report and save the report in evidence, save the report.

  If you are using a relatively recent version of LabVIEW (2010 or later), the new generation Excel report screws are pretty easy to use.
