Double each of them, of course
I think someone said that apache has an open source csv reader/writer library... which I presume would conform to the "best open standard" whatever that it is, and hence take care of all this crapolla for you.Very likely. Google will probably turn up a bunch.

How to import data from CSV file with columns separated by semicolon?

I migrate database from MS SQL 2008 to ORACLE 11g
I export data to CSV file from MS SQL
then I try to import it to Oracle
several tables goes fine using Import data option in the SQL Developer
Standard CSV files with data separated by comma were imported.
chars, date (with format string), and integer data are imported via import wizard without problems
the problems were when I try to import table with noninteger numbers with modal part separated by comma not by dot
comma is the standard separator for columns in CSV file
so I must change the standard separator to semicolon
then the import wizard have problem to correct recognize the columns data because it use only standard CSV comma separator :-/
In SQL Developer 1.5.3 Tools -> Preferences -> Migration -> Data Move Options
I change "End of Column Delimiter" to ; but it doens't work
Is this possible to change the standard column separator for import data wizzard in SQL Developer 1.5.3?
Or maybe someone know how to import data in SQL Developer 1.5.3 from CSV when CSV colunn separator is set to semicolon?

A new preference has been added to customize the import delimiter in main code line. This should be available as part of future release.

How to store data (in tdm files)

I'm looking for advice on how to store data in tdm/tdx files.
The main challenge is like this: At regular time intervals there is new data available (say every 10 minutes there are 10 minutes of new data available). All data is time based. So every ten minutes I may create a new tdm/tdx file containing this data segment. However, when i want to analyze the data i dont necessarily want to view 10 minutes of data from all channels, but maybe 20 hours of data from one particular channel.
The way I've achieved this so far is to manually load each 10 minute segment of this particular channel and then add these parts together. This is both time consuming and cumbersome. Is there a better way to do this that I've simply not discovered yet? Is there a better way to store data to simplify this process?
One solution is of course to save data from several 10-minute frames in one file, but seeing as there is a never ending supply of data i cant simply save all data in one giant file, it has to be split up at some point, and the problem will still remain.
One factor to have in mind here is that this is rather large amounts of data (maybe 10GB each day), so the option to simply load all the data into memory goes out the window rather quickly.
Feel free to ask if I've not made myself very clear

Hi salte,
If your test ever ended, and if you had LabVIEW 8.20 or higher, I would recommend using a TDMS file, which handles data appeands flawlessly. DIAdem 10.1 now also does data reduction and index windowing during file loading for TDM / TDMS / DataPlugin files, so that you could easily load out only the part of the file you wanted to look at. But since you describe your data acquisition as never stopping and amassing 10 GB per day, I agree that it would be impractical to use only 1 data file. So we are stuck with some number of files which each contain a part of your measurement. This approach can have advantages, since you can save operational properties for each "buffer" such as average value, dominant frequency, ambient room temperature, etc., and later on you can use the DataFinder to query out only the data buffers which meet specific conditions based on these properties. The problem remains to load and assemble data based on multiple files. This is an old problem in DIAdem, and one for which I have an efficient and I hope satisfactory workaround application. It does what you describe already doing in the minimum amount of time and with the minimum amount of user interaction, and it can be highly parametrized to suit your particular situation. The ideal way to start the application would be as part of a ResultsList custom menu. This would enable you to query out the buffers you wanted, highlight those rows in the ResultsList, right-click and choose your custom menu, and WHAM! the selected buffers for your queried channel(s) are automatically appended together in the DataPortal. Launching from a ResultsList custom menu would mean that you could skip the file dialog and just read out the data sources directly from the ResultsList selection.
Let me know what you think,

How to saving data in csv file

I have problem with saving data in csv file. I would like save my data look
like this example :
excel preview :
A B C
1 10 11 12
2 13 14 15
As we see all values are in separate cell A1=10, B1=11, C1=12 ...
so I try :
PrintWriter wy = new PrintWriter(new FileWriter("test.csv"));
values[0][0]="10";
values[0][1]="11";
values[0][2]="12";
values[1][0]="13";
values[1][1]="14";
values[1][2]="15";
for (String[] row : values){
for (String col : row) {
wy.print(col + "\t");
but csv file look like :
A1=10 11 12
A2=13 14 15
but B1-B2 and C1-C2 is empty
the second steep is use Ostermiller library :
OutputStream out;
out = new FileOutputStream("temp.csv");
CSVPrinter csvp = new CSVPrinter(out);
String[][] values = new String[2][3];
csvp.changeDelimiter('\t');
values[0][0]="10";
values[0][1]="11";
values[0][2]="12";
values[1][0]="13";
values[1][1]="14";
values[1][2]="15";
csvp.println(values);
but the result is also this same, is anyone do how to resolve this problem
?

but iI don`t want to seperate with comma....value
I
want to seperate each value to seperate cellWhen you save the file, separate w/ comma
When excel loads it, it will automagicarifficallyput
it in it's own cell.what it is "w/ " ? when I separate my data with
comma excel don`t put value to spererate cells"w/" is an abbreviation of "with". Post the code that doesn't work, along with the results you get. If it's not working with commas, you must be doing something else wrong.

Help Me... How to get Data from CSV File...?

Hi Everyone..!
This is yajiv and am working in CS3 Photoshop platform. I know about Java Script. Is it possible to get the data from CSV files. Actually our client use to send us the CSV files which contains a lot of swatch name and reference files in one particular image name.
Actually how we work on that CSV file is, first we copy file name to search that CSV file. then get the result to paste into layer name. This process continue till the end of swatch.

How to store data in a file without using DB

Hi all
I want to develop a small application that could contain at most 10000 records, so if it is possible I want to store the data in a file, therefore the installation of the application can be simplified and the users don't need to add a ODBC dataSource in the control panel before running the program.
If the above is not possible. Does anyone know how to use Java to programmatically add a ODBC dataSrouce in the control panel in the Windows Platform?
Thank you very much !
Kind Regards
Edmond

1 ) Save the records into a vector and write it to a file. You will have to load all the records when you read the file though.
2 ) Use a dsn-less connection. You do not need to have a dsn set up and you can access a file using the bridge driver:
url = "jdbc:odbc:Driver={Microsoft Excel Driver (*.xls)};DBQ="+file.getPath();
               //Obtain the driver for the
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
               //Create the connection
               con = DriverManager.getConnection(url, "", "");
               //Ensure that the connection allows two way commands
               if (con.isReadOnly()) con.setReadOnly(false);
               //Create the statement to be executed
               stmt = con.createStatement();
     //execute the select statement
               ResultSet rs = stmt.executeQuery("SELECT * FROM \"Sheet1$\"");
This should work, let me know if it dwosnt

How to export data to .csv file ?

Hi guys, I know this topic is covered many times in this forum. How do I export my table data to a csv file when my data already has some , (commas) in it. For example, I have two columns in a table, ID and DESCRIPTION. The DESCRIPTION column has data which has , (commas) in it. When I export the data using the following script, I see multiple columns in my excel file as DESCRIPTION has data with commas and each part of it is shown as a separate column in excel sheet.
set heading off
set echo off;
set pause off;
spool tbl_account.csv;
select To_Char(ID)|| ',' || To_Char(Description) From tbl_account;
spool off;
Thanks in advance

Have you thought about putting those values between quotation marks?
"test,test" for example would end up in one cell.

How to store data into log file(.doc) using CVI

The purpose is to store the capture data(from my cvi program) and store into the log file (.doc). so at the end of the program run I can retrieve the doc file where the data store to do my analysing .
Why do this: I wanted to create my program into .exe file that why I need this method or do u have other method to intro?
Any ideal or note or example to share? Pls help

If you are explicitly trying to create a Microsoft Word document, then CVI comes with Word Report instrument that can be used to generate such files. The instrument is located in toolslib\activex\word\wordreport.fp, while a sample program can be found in samples\activex\word\wordrpt.cws.
I suggest you take a look at the example program that illustrates the fundamentals of this instrument, next you can start designing your own application using that instrument.
Proud to use LW/CVI from 3.1 on.

How to export data to csv file on a scheduled basis

Hi,
I'm trying to do something that should probably be simple but I just can't figure it out.
I have an existing MS SQL database (2008 R2). I have a very simple SQL script. I need to run this script on a daily basis and save the results as a .csv file.
I've tried creating a job in SQL Manager - that didn't work. Then I found a tutorial that had me use MS Visual Studio... couldn't get that to function either.
Can someone help me understand what program I should be using, and how to go about creating this as a task / job that can run on a scheduled basis?
Thank you!
Chris

Hi, you can follow the below steps to get your work done -
Create a batch file (.bat) and dump the following text into it
          sqlcmd -S myServer -d myDB -E -Q "select col1, col2, col3 from SomeTable" -o "MyData.csv" -h-1 -s"," -w 700
          Replace myServer with your server name,
myDB with your Database name and then replace the query with your actual query.
         -h-1 removes column name headers from the result
         -s"," sets the column seperator to ,
         -w 700 sets the row width to 700 chars (this will need to be as wide as the longest row or it will wrap to the next line)
Save the batch file and the schedule it as per your requirement.
Hope, that helps.

How to store data into a file from a host VI developed for Compact RIO

Hi,
I am new to the CompactRIo.I have developed a VI which runs on the FPGA(CompactRIO) which continuously monitors tha data from a system and i have developed a host VI to read the data and i am successfully getting the data into my computer and i want that data to store into a file.When i use the write to spreadsheet VI for writing into a file.The data is not written into file can anybody tell me why this is happening?

Hi,
The last one you said is working when i conected through it is working, whatever files i have used earlier are there.Thanks for that but i have few queries please answer me so that i acn proceed in my project.
1.As you said to connect to ftp://xx.xx.xx.xx i have seen some extra files along with my files waht are they? waether my data files are stored in flash memory of RT controller?if so, how to clear those files?
2.Suppose i want to clean up the flash memory of RT contrller i.e suppose i have deployed some file earlier , now i want to cleanup those i dumped into the memory how to do that?
3.How to disable the Application running on the RT controller when it powers on? i.e. when i switch on the power it should be connected but nothing hould be running on.
4.I mean at the end of the experiment when i stopped the host VI by pressing stop button weather application running on the RT controller will stop and weather FPGA VI runnibg on that also stop if not how to stop?
5.Suppose next time when i connect to ftp://xx.xx.xx.xx i dont want to keep earlier files there how to delete them?Because my doubt is if i am using the file name which is same as the prevoius one there is aproblem of appending the new data to the old file.?

How to import data from CSV files to OIM?

Hello,
We have to import some of the files which are in csv format and are placed in a specific folder hierarchy. Please help as i am not able to proceed further.
Thanks a lot!

To write custom scheduler tasks you need to write a class which extends SchedulerBaseTask class.
See this link. Re: Custom reconcilation
Also GTC flat file retrieves data from file and creates identity/account in OIM. You can use either ways to meet your requirements.

What is the best way to store data to a file? Serialization?

FYI: I am some what of a novice programer. I have almost finished my degree but everything I know about Java is self taught (never taken a course in java). Any way here is my question.
So I have an example program that I have created. It basically just has three textpanes which also have the ability to contain images. Now I would like to learn how to store data to a file for later retrieval and decided to use a program such as this as an example. I am not sure if I should use the serialization API that java has or some other means such as XML. If I used XML I was not sure how to store the image data that would be contained in the text panes. I figured serialization would take care of that if I just serialized my main class and then restored it. So That is that I tried first. Is this a good direction to go?
The problem I am having is that I cant seem to get the serialization to work the way I need it to. I am not sure what I am doing wrong because I have read many tutorials and looked at allot of example code but still dont understand. The tutorial I looked at most is [this one at IBM.|http://java.sun.com/developer/technicalArticles/Programming/serialization/]
The eclipse project folder for my example program can be found here:
[http://startoftext.com/stuff/myMenuExp/]
zipped version:
[http://startoftext.com/stuff/myMenuExp.zip]
The main class is mainwindow.java. I know the source is kinda dirty. Any comments are welcome but I am most interested in how to solve this serialization problem. Thanks

What will the nature of the data be? Just a handful of strings? A bunch of objects of different types reflecting the current state of your program to great depth and complexity? Something else?The data will be what is contained in three text panes. Each text pane containing rich text and images. For an example take a look at the example program in my first post.
How will the data be used? Just write it out when the app shuts down, and read it all back in when it starts up? Do you need to query or search for specific subsets of the data? Is there any value in the stored form of the data being human-readable?Basically the data will need to be saved when the application shuts down or when the user selects save from the file menu. The data will be restored when the user opens the file from the file menu. It would be nice if the stored data is human readable but its not of primary importance.
How often will the data be written and read? How many reads/writes/bytes/etc. per second/minute? Not often. Just a simple open and save from the file menu.
How large could the data conceivably get?It will probably be a few paragraphs of formated text and less then a dozen images per text pane.
Will reading and writing of the data need to occur concurrently?no.
Do you need to add new data to the storage as your app goes along, or just replace what's there with the most current state?Replace with the most current state of the data.
If it's a simple read once at startup, write once at shutdown, overwriting the previous data, read only by your app, not by humans, then serialization via ObjectInput/OutputStream is probably the way to go. If there are other requirements, you may want to go with XML serialization, a DB, or some other solution.Thanks for the information. Serialization sounds like the way to go. Even if I end up using XML serialization in the end it would still be of interest to me to learn how to use serialization without xml.
I was trying to go with using serialization in be beginning but I cant seem to get it to work. Would you be willing to take a look at my example program. I attempted to implement serialization but it does not seem to work. Could you take a look and see what I am doing wrong. At this point I am stuck as i cant seem to get serialization to work.
I am going to go ahead and mark this thread as answered because I think I already got most of the information I was looking for except what I am doing wrong with my attempt as serialization.
Thank you jverd for your time.
