Write records to file???

i know how to write lines of information to a file and output them but how do you go about writing records in one file and then retrieving them for use within a program, if someone could help by posting some simple code, or explain where i could find this id appreciate it
Thx

If you are refering to Records as objects, then you could serialize them into a file. You would create an ObjectOutputStream object, then call writeObject() for each object you want to write out. Then, using ObjectInputStream you would read them back in with readObject(). You can also write the number of objects in the file first by calling writeInt() before calling writeObject() in a loop. Reading would then be the exact opposite, call readInt() to determine the # of objects in the file, then calling readObject() x number of times.

Write Record to File

Hi all
I am now doing a java program to query result from SQL Server and write the result to a file.
My problem is that our SQL Server stores Chinese wordings with unicode, after the program query the result and it fails to write those Chinese wordings in the file. I have tried to use ObjectOutputStream or DataOutPutStream with method like writeBytes, writeChars or WriteObject, but all are failed to create a ASCII file that can view the Chinese wordings. Although those words can be viewed by using Sytem.out.print().
I think the problem is related to write the result to file or create the file, can any one help?
Thanks

ShekWhich editor are you using to view these files ? It might be possible that not the file but the editor could be the problem.
You might also want to investigate OutputStreamWriter and related classes.

How can I read, millions of records and write as *.csv file

I have to return some set of columns values(based on current date) from the database (could be million of record also) The dbms_output can accomodate only 20000 records. (I am retrieving thru a procedure using cursor).
I should write these values to a file with extn .csv (comma separated file) I thought of using a utl_file. But I heard there is some restriction on the number of records even in utl_file.
If so, what is the restriction. Is there any other way I can achive it? (BLOB or CLOB ??).
Please help me in solving this problem.
I have to write to .csv file, the values from the cursor I have concatinated with "," and now its returning the value to the screen (using dbms_output, temporarily) I have to redirect the output to .csv
and the .csv should be in some physical directory and I have to upload(ftp) the file from the directory to the website.
Please help me out.

Jimmy,
Make sure that utl_file is properly installed, make sure that the utl_file_dir parameter is set in the init.ora file and that the database has been re-started so that it will take effect, make sure that you have sufficient privileges granted directly, not through roles, including privileges to the file and directory that you are trying to write to, add the exception block below to your procedure to narrow down the source of the exception, then test again. If you still get an error, please post a cut and paste of the exact code that you run and any messages that you received.

SQL> The program wrote 5 records into the file.txt (5 calls). Normally i must write
at about 2 million records into the file. It is possible, to write the records into
the file with one call, like a array or a ref_cursor (input parameter of the function write_file) instead of calling the function 2 millon times in a loop?

Couldn't help commenting cos that has got to be one of the best drive/folder name combinations I've seen in a long time. :))
v_FileHandle:= UTL_FILE.FOPEN('s:\hit', v_FileName, p_FileModus, C_MAXLINESIZE);Seriously though, when working with UTL_FILE you should use directory objects to ensure proper security... note...
The UTL_FILE_DIR parameter has been deprecated by oracle in favour of direcory objects because of it's security problems.
The correct thing to do is to create a directory object e.g.:
CREATE OR REPLACE DIRECTORY mydir AS 'c:\myfiles';Note: This does not create the directory on the file system. You have to do that yourself and ensure that oracle has permission to read/write to that file system directory.
Then, grant permission to the users who require access e.g....
GRANT READ,WRITE ON DIRECTORY mydir TO myuser;
Then use that directory object inside your FOPEN statement e.g.
fh := UTL_FILE.FOPEN('MYDIR', 'myfile.txt', 'r');Note: You MUST specify the directory object name in quotes and in UPPER case for this to work as it is a string that is referring to a database object name which will have been stored in uppercase by default.

Why all the ugly upper case? You do realise that NO programming standard, ranging from Java and .Net, to C/C++ and Ada (of which PL/SQL is an implementation of), use upper-case-for-reserved-words as a standard.
The easiest and simplest way to address your requirement is as follows:

Write to measurement file at every n iterations

Hi guys,
I would like some help with saving data in labview 2010 SP1 (base development system). I am using a "Write to measurement fil express VI" inside a while loop and the data out from the DAQmn Read is wired to the signal in of the "Write to measurement fil express VI".
The way I have wired it is the VI saves the data as a text file after it has recorded 100 samples (the nuber of samples to read in this case was set to 100). I would like to know if there is a way to control the rate at which the express VI saves the data. As in, I want the express VI to save the data at specified time interval or at every nth iteration. I have attached the main VI and its 2 sub-VIs for reference. Please let know if anyone can help me resolve this issue. Thank you for your time and inputs in this regard.
Raj

Robert,
First, you must understand that the above code resides inside a loop. The blue square i terminal is known as the iteration terminal. It provides the current loop iteration count, starting from zero.
The first input (x) to the Quotient & Remainder Function comes from this iteration count (i) terminal of the loop.
The second input (y) to the Quotient & Remainder Function comes from the control N.
We wish to write to the measurement file every N iterations of the loop. If we take our current iteration count (i) and divide by our desired N, every Nth iteration of the loop, the remainder will be zero. For all other iterations, the remainder will be non-zero.
That being said, we check the remainder and compare it to zero. If it is zero, we will send a True value to the Enable terminal on the Write To Measurement File Express VI. Any time a True value is sent, we will write to file. Anytime a False value is sent, nothing will be written to the file.
The green new_file input on the Write To Measurement File Express VI is used when the "Save to series of files (multiple files)" radio button is selected in the Configure dialog box of this Express VI. When "Save to one file" is selected, this option does not apply, and so it is not included in the input list, which is why you are not seeing this.
This new_file input is used to tell the Write To Measurement File Express VI when to start writing to a new file.

HELP: Appending new records to File containing 1 Record

How to put the proper header at each column in write to measurement file (.lvm) ?

Hi,
i would like to know one thing about the write to measurement file. Can i put the proper header at each column in write to measurement file (.lvm) ? and how can i do for it ? Could you show me a way to make it ?
i am looking forward your kindly reply.
thank you so much ..

Hi Mike,
Thank you very much for your help. It works .
By the way, i would like to ask you about setting time interval. In the pic, X_Value column is for time column
i would like to ask that when i use the write to measurement file, there got the x column that show time inside the excel file. In this column, i would like to set the time interval at every 210ms .The data may come in every msec but i just want to record the data at every 210ms . for example, 210ms-420ms-630ms ..etc. how can i set it ?
One more thing .. can i do it in graph as well ?
i am looking forward your kindly reply.
Thank you for your time.
Best Regard,

Write to measurement file timing

I am trying to make a VI that allows the user to turn on and name channels through the front panel. After the user has configured the channels, they can push a button and record voltages from the enabled channels and save them using the "Write to Measurement File".vi. I would like the user to be able to record a measurement file that is consistent in length each time they push the button...in this case, 5 seconds of data. The current VI doesn't appear to be doing this...everytime I push the record button, the data gets recorded for 0.045 seconds. Apparently I must be missing something as this isn't behaving how I expected it to. See attached VI.
Attachments:
Select Channel rev 3.vi ‏244 KB

It waits 5 seconds then saves the last 10 samples. Because that is the way you programmed it. The while loop returns only the data from the last iteration.
Two ways to do what you want: 1. Read 5 seconds * 200 samples/second = 1000 samples. No loop required.
2. Read 10 samples at a time and accumulate the data until you have 5 seconds of data. To avoid memory reallocations the way to do this is to Initialize an array with 1000 elements outside the loop. Wire it to a shift register. Inside the loop Read the samples and use Replace Array Subset to put the new data into the initialized array. Wire the output of the shift register to the file VI.
You generally should not put any time consuming code inside an event structure. Read the caveats in the detailed help for the event structure. Consider a Producer/Consumer architecture.

Strange data saved by write to measurment file

Hi all,
I have developed a simple program that permits to visualize data from a channel, but it records data, just when the saving data button is pressed. Data are saved through write to measurment file, but unfortunately there is something wrong since the saved data is strange. In the attachment there are the VI file and the saved data.
As you can see there are several header and dates are strange (i.e. the saving date is 23/12/1916) and I get much more sample than I should have. Why do I get this?
Any suggestion is appreciated.
23/12/1916

RSEOUT00 failing with "Could not write IDoc to file" TPRI_DEF table

Outbound Idoc processing fail with the following error:
Could not write IDoc to file
Message no. EA299
Diagnosis
The system could not convert data from the data record 000027.
Procedure
Check the port definition of the receiver port.
You can use the "Continue despite conversion error" option to write the IDoc to the file from transaction BD87 with replacement characters.
Short dump indicate that there is a some junk character in th e TPRI_DEF for program SAPLSPRI that it is unable to convert.
I have set the flag on the we21 port to "continue despite conversion error" and that seem to help, but I would like to figure out how to fix the junk characters from coming through from the TPRI_DEF table.
This is what shows up in the short dump after RSEOUT00 is run.
TPRI_DEF                                   / /       : :     00002932
    010GV21            \0\0\0\0\x0006āȂ耀㐱〲\0\0嬇\0ሟ鴂푎眩\x0802儔잏퉓
I do not see any entries for area "GV" in the table, there is one for "GF". which has no user assigned to it and it is of key version 21.
I am not sure if the table is supposed to have an entry with no user assigned?
thank you for looking at this issue .

HI Jurgen,

Pls adivce..

Write measurement files filesize

Hello,
i record a lot of data from my plc and want to write it to a measurement file in tdms format.
the problem is the files are very big, if i use the "write to measurement file"-express-vi.
If i use the"TDMS Write"-Function instead the files are much smaller, with nearly the same settings.
Is there a way to use the Express-VI with the same effiency if i would use the "TDMS Write"-Function?
Why are the files so big if i the express-vi?
Solved!

You needed to use a shift register to hold your Signals. Then it keeps the values you added between iterations.

Write an excel file using File adapter

Hi,
I have a scenario in which i have to write an excel file in the target system.
I tried creating a tab delimited file conversion and just named the file as .xls.
When i saw the output file it did look like a excel but a report that i have written to read a excel file cant read it.
The report says 0 records found. It works for other excel sheets that are created manually.
So will this method noit work for creating excel files?
Is using the jexcel api the only option for this?

Have u had a chance to see this excellent blog by shabarish...
