• Call a script from a function sql file.

  Hello
  I need to call a script file sql from a user-defined function. Currently I am doing this in Oracle SQL Developer. I tried to call with
  @ {filename}, EXECUTION IMMEDIATE etc, but nothing worked. I get the compile error.
  
  Basically, my need is to call catldap.sql file so that DBMS_LDAP package gets loaded and then I can call this API functions.
  Please let me know if this is possible to do in a PL/SQL function.

  Not possible... and it seems that you do not fully understand the client-server in the context of Oracle.

  All SQL and PL/SQL are parsed and executed by an Oracle server process. Engines SQL and PL/SQL is expecting a single command at a time block. Any of these can accept a series of commands in a single call and then runs them in turn. The SQL engine expects a single SQL statement at a time. PL engine provides an anonymous PL/SQL block for both.

  This server process can not also enter the local file system to access the script files. Nor can he hack it on the network to access the script on the client files.

  So that the server process to access local files, a Directory object must be created and the current Oracle schema must read or a write access to this directory object. Sound security principles apply.

  There is no PL/SQL command to run a script. Do not confuse SQL * more (this customer has a very limited vocabulary) orders with PL/SQL commands. SQL * Plus runs its own orders... and send SQL and PL/SQL commands (a statement block a time) either repaired and running Oracle server process.

  It's also a very bad idea to run the external script content from within an Oracle server process - as this script resides outside and so outside the Oracle security mechanisms. This means that it is fairly easy for a person to access this script, compromise and then you inject and execute the contents of this script in the database.

  It is not good security.

  Latest issue - it's even worse to have the PL/SQL application dynamically create (or try to create) parts of the Oracle data dictionary and calling PL/SQL interface.

  The database must be installed correctly - and that includes loading and execution of the required rdbms/admin scripts during installation. It makes no sense at all for the application code to try to run these scripts. It raises many questions, including getting to allow the full application and full SYS code access to the instance database. A very serious breach of security.

  I agree at all with the approach to use.

• How to transfer data from the data in table 2D only once file?

  Attached file will write same data in table 4 times 2D file. Output must be in a table 2D.

  Someone will provide a solution or a reason to explain why the data are been ouputted 3 more times? Thank you

  I already told you a better and more effective method. The function of reading worksheet is on the exact same range as your text file and does everything for you. If you insist for some reason strange kernel to reinvent the wheel and write your own code, take the correct path. The use of 4 separate spreadsheet String to Array is the cause of your problem and I already said too much. Don't you think that get you 4 times the data is in correlation with the fact you are using 4 times the functions necessary at all? It is simply not true. Look at the diagram-writing block on a spreadsheet file.

• Control of data rows Excel (write on a file of measure)

  Hi all

  Objective:

  Get a bit of a live waveform of two pressure sensors, as well as calculate the differential pressure. The LabVIEW VI is intended for students for an exercise in module, in which data are exported to an excel file for the students to perform other calculations. Excel file must contain data from the beginning to the end of a race.

  Problem:

  Pressure sensors work well, waveform table works well, but when you stop the collection of data, the amount of lines in the file Excel output will reflect the number of samples per channel of the DAQmx Read Block (10 = 10 rows of data, 100 = 100 lines, etc.).

  I would appreciate some advice on how to conduct the data collection in the part worksheet from start to finish, without this affecting the aesthetic experience of the student (by that I mean the number of channels of the > 10 sample will cause some lag in the waveform, jerky). I tried to resolve this issue with something in the sense of Tank1Solution.png without success. I've included a photo of the original block (Tank2Block.png) and so I worked the file VI.  Once more, any help would be much appreciated, I'm not well versed in LabVIEW and I do not know how to address this problem effectively.

  Some guys are always doing things the hard way

  

  Of course, you need a son to ai0 - ai2 and ai1 - ai9.  This linear scale DAQmx is of course very convenient! and hey, the TDMS files import beautifully into Excel! the addon is there then why not just open a session data?  TDMS is much more portable than xlsx.

  A few additional remarks. (a) you can't stop this vi before you press Go-who needs a fix. (b) Create scale is likely to return an error as it is the name being illegal. I named it that to show the source of the scale and offset values.

• Configuration 'use the next available filename' in function 'write file measure. "

  My signal to record project and recording by using the function "write into a file position. I want to make the recording of signals multiple segments must have configured option «use the next available filename» For example, if the original file is data.tdms, then it saves the file in: data_1.tdms, data_2.tdms, data_3.tdms,...
  Do I use a button control enable and disable the feature of writing.
  In the past, I did normally. Now, I can't do more, now, each writing new data have been add in a single file created without the next new file as you wish, it has almost become an option "add to the file".

  I use LabVIEW 2013

  Hello ducta9,

  Looks like you're currently writing custom file Express VI configured to 'save to file' - this means that all the data for a given session will be saved in the same file.  The file number will be incremented only once the application is restarted or the Boolean Reset entry has the value True.  If you want to save on a series of files, select the option "Save to a series of files" and configure the Express VI as needed to generate new files at intervals.

  If you want to write blocks of variable data to a new file size whenever the user clicks the Activate button, you may be able to get away with wiring just a real constant for the Reset.  I would recommend when to even take a look at the options available in the recording of a series of settings files.

  Hello

  I tried to change the .xlsx to .xls and it gives a note at the opening of the file "the file you are trying to open, abc.xls, is in a different format that it is specified by the file extension. Check that the file is not corrupted and precedes from a trusted source before you open the file. Do you want to open it now? »

  When you rename the file does not solve your problem.
  Anton Scheffer package generates a file in format xlsx Office 2010. When rename you it with the .xls extension, then Office 2010 will give you the warning that the file format does not match the extension.

  but the requirement has to generate excel 2003 file.

  The xml_spreadsheet package writes a format that was introduced with Office 2003, but you must use .xml as extension in other Office 2010 will give you the same caveat.
  To write the real xls version (binary), you can use Apache POI. You will need to import Java classes in your db and write a PL/SQL wrapper. Or you can use one of the options above, writing the output to a windows server and then use Excel to open and save in the required format.

  You must decide whether it is easier to write the binary xls format or to convince the customer to accept other formats that can be opened with Excel.

• write to measure file vi bug?

  Hello.

  Looks like I might not be the first with this.  I suspect...

  http://forums.NI.com/NI/board/message?board.ID=170&message.ID=234485&query.ID=1018110#M234485

  I still after that I don't know how many hours days etc., failed to do this work.   I had to go and do a 'real' job, as it is called here for a few days or so, don't play no not with the software, however, is that asked me to do.

  This is all about 'Writing as Data File' express VI comes with LV 2009.   Used as Cree in the document "Getting started with LabView" infamous.   Running on XP Pro, perfectly (until tomorrow "Patch Tuesday" maybe.)

  Writing on a data file Express VI:

  It works the first time, no mistake, a lot of data, the first time entry to activate is made true, even if I leave it is true, thankfully, it creates several KB of the planned just as data file.   Do activation enter False, writing to the file STOPS, again just as expected.

  New do right and produces an error (the chemin\nom of the input etc file is still there and equally valid that it has always been) and no data is written in the file, despite no changes to the inputs of the VI (with the exception of the data of unique signal value)

  However, if give you him a new one (same file path\new) file name, and then he would write in the new file every time.  It's without blocking the program as a whole.

  I can navigate between two files just fine.   But it just will not write to a file first, that it is "Re" active after a deactivation is used.  Re entering the same path\filename is not a solution.  It must be another to wake up the thing.

  As it is, it's worse that useless for any serious application, and as the other party, I can't imagine how he got through the mill of QA.   As the other party, it is sold on the fact that it is supposed to be easy to plant items/icons on the comic and join the dots to make things work.  While largely true and there are a lot of good stuff here, there are a lot of things that exist for travel upward and confuse him.   The help is too small.  I get the phone call and email to other types of NOR, but no solution to the problem.

  If you want a copy of the VI program all the so-called fine, just someone tell me what and how to download it on this forum (very strange).  I can upload images, but I can't find a way to "attach" files, etc.  Or to work through the Getting Started document (as I have now three times!) and you will find the problem.

  Oh, and I seem to have lost the indicator as to how much
  days of "evaluation" I left.  I can't find a switch to make it appear that
  Gray more splash screen.

  Kind regards.

  I think that there is certainly a bug.  I can see where it is going, but I don't know why he got that way.  This VI shows the bug in LV 8.6 also?

  Right click on the entry to measurement file Express VI.  Inside that is a Subvi, called ex_subFileWrite.vi.  It is a clone of a reentrant VI, so it is quite difficult to follow execution through it.

  Somehow the first time through she builds and checks the file name based on what comes into it.  She that stores into a shift register.  If you clear the writing to a file, the shift register is stored which is not a constant of path.  Later, when writing is reactivated, it uses just the path (not a path) from the shift register, rather than back in the name of the input file.

  Exactly where this is really out there, I'm not sure, because express VI makes such a spaghetti with inter twisted code for managing all types of files and in writing the conditions and a lot of manipulation of file file path.

  I think the reason that edit the path and even change back works is that there is an initial control if the path is the same and if it is different, it works with the new file name, if it isn't, then it works with what was stored in the shift register.

  A person of OR should look deeper into this substantive code of the Express VI and try debugging.  I think that there is a bug.

  But here's a work around.  Use a select statement to send the correct file name if the writing is enabled, or a file path empty if it is not enabled.

  

• prompt user with write to measure file VI

  Hello

  I have a Labview VI who is writing data to a file, currently the file name (path) is written in the section "Filename" of writing on a file measure VI.
  Is it possible that a user can be prompetd for a file name?

  As in,.

  time each time I run the VI a diaglog box appears, which allows the user to type a specific file name (say Run1 or Run 2, etc...). The user types the name of the file must match the name of the file where the data is written (using writing to the file as VI)

  I enclose my vi of the trial.

  You know measurement files have an extension of "lvm" (as configured in your ExpressVI)?

• Writing data to extend the acquisition of data for the sampling rate high file

  These are the tasks that I have to do to take noise measurements:

  (1) take continuous data to USB 6281 Office, in a sample of 500 k (50 k samples at a time) rate.

  (2) save data continuously for 3 to 6 hours in any file (any format is OK but I need to save in a series of files rather than the single file). I want to start writing again file after every 2 min.

  I enclose my VI and pictures of my setup of the task. I can measure and write data to the file continuously for 15 minutes. After that, I see these errors:

  (1) acquisition of equipment can't keep up with the software (something like that, also with a proposal to increase the size of the buffer...)

  (2) memory is full.

  Please help make my VI effective and correct. I suggest to remove him "write in the action file" loop of consumption because it takes a long time to open and close a file in a loop. You can suggest me to open the file outside the loop and write inside the loop. But I want to save my data in the new file, after every 2 min or some samples. If this can be done efficiently without using Scripture in the measurement file then please let me know.

  Thank you in advance.

  This example here is for a single file and a channel, you should be able to loop over that automatically. The background commentary should be the name of the channel, no group namede the name of the channel in the control.
