Retrieve data from a text file and insert in table

hi,
i am writing an application which when executes would creates a user table and populates it with the data i.e. username and passwords taking it from a text file.
i would like to know if anybody can help as to how can i retreive the user name and password for every insert statement that will be fired to populate the user table.
thanks in advance for the help

for csv try a little search:

Retrieve data from one numbers file and insert it in another?

My goal is this: I want to essentially link two numbers files. I need data from several different tables in different sheets to automatically populate cells in a totally separate numbers file.
Here is why: I have very detailed orders that all feed (link) to summary pages that are shared with clients. I also need that same summary information, however, to feed to another file that calculates the margins. The summary pages (sometimes dozens of pages) are critical for clients to see, but as you can imagine, the margins tables must never be seen by the clients. My preference is to have them be totally separate files so it eliminates the possibility of the margins table every being accidentally sent to clients.
I'm wondering if applescript is the only or best way to accomplish this, or if there might be a more simple solution.
Thanks in advance.
Bob

It may be done with a script but as I have no info about the structure of the document and about which values must be passed, I can't help you.
More, I doubt that you are sending the Numbers document to your clients because this app isn't widely used.
My guess is that you print the file in a PDF.
The number of pages in the PDF will dramatically change if you include the sheets containing the margins so, it would be easy to check if you built a wrong document.
To do the trick with a script, it seems that the easiest scheme would be:
duplicate the original file
add the columns required for the calculations
create the formulas and insert them
copy the relevant columns
paste them in the original document.
I'm reluctant to work this way. The risk of errors is too big.
Here is an alternate scheme.
In your document, change the layout so that columns which are supposed to be seen by clients are contiguous.
This way, you may easily hide the columns which you want to keep 'secret'.
I don't know the way you are working but with a bit of luck, once the formulas are built, maybe you have no need to unhide the 'margins columns'.

There are so many things wrong with this VI, I'm not even sure where to start.
Hard-coding paths that point to your user folder on the block diagram. What if somebody else tries to run it? They'll get an error. What if somebody tries to run this on Windows 7? They'll get an error. What if somebody tries to run this on a Mac or Linux? They'll get an error.
Not using Read From Spreadsheet File.
Use of local variables to populate an array.
Cannot insert values into an empty array.
What if there's a line missing from the text file? Now your data will not line up. Your case structure does handle this.
Also, how does this answer the poster's question?

I need to read data from a text file and display it in a datagrid.how can this be done..please help

hey ppl
i have a datagrid in my form.i need to read input(fields..sort of a database) from a text file and display its contents in the datagrid.
how can this be done.. and also after every few seconds reading event should be re executed.. and that the contents of the datagrid will keep changing as per the changes in the file...
please help as this is urgent and important.. if possible please provide me with an example code as i am completely new to flex...

It's not possible to read from a file without using classes from the core API*. You'll have to get clarification from your instructor as to which classes are and are not allowed.

Compare data from 2 text files and output match

Hi all,
I need some advice.
Firstly in BinaryCode.txt the data is as such:
Replace BinaryCode0 1 0 0 0 0 0 0 0 0
Replace BinaryCode0 1 0 0 0 0 0 0 0 1
Replace BinaryCode1 1 1 1 0 1 1 1 1 1
Replace BinaryCode1 1 0 0 0 0 0 0 0 0
the first line in the text file is the header. So I need to check if the names in the second column (BinaryCode0 or BinaryCode1)appear in the Timed_Sets.txt file.
The data in Timed_Sets.txt is as such:
BinaryCode0,6,40,.........................
BinaryCode0,7,40,.........................
BCName1,0,20,.............................
BCName1,1,20,.............................
For example since BinaryCode0 is a match I will output the entire row in Timed_Set.txt to another array.
I have been working on a program but I don't get the expected output.
The text files and the VI are attached.
I appreciate your kind assistance in the matter.
Thank You

If I understood correctly what the output should be then what you basically need to do is to walk through the column in BinaryCode.txt and for each unique value pull out the corresponding rows from Timed_Sets.txt. There's a variety of ways to do this, depending on how much data you have and whether or not you can use any kind of prior knowledge as to the actual file content (such as the names of the keys being searched). Attached is one way. Modify as needed.

Retrieve data from a text file, incrementing the last value and save new value below

Hi
This was working initially. It is part of my LabView Project. I was trying to create a unique number that increments every time the adds the value to the list. It works on computer perfectly. But when I put this on a PDA, it seems to create a blank space when reading the contents of the text file after the last value, which means 0 + 1, which is not what I want.
Please run the testUniqueNoOnPDA.vi first and change the path to C:\uniqueNumber.txt and save the uniqueNumber.txt file to your C drive and see What I am trying to do. Click the Enter button to increment.
Why does the PDA create a blank space after the last value and a computer does not?
I was working perfectly all week and it is not working well now.
Help please, I think I'm missing something

Shell scripts to read data from a text file and to load it into a table

Hi All,
I have a text file consisting of rows and columns as follows,
GEF001 000093625 MKL002510 000001 000000 000000 000000 000000 000000 000001

the whole application is deployed in unix and that text file comes from mainframe. am working in the unix side of the application and i cant access the data directly from the mainframe. so am required to write a script which reads the data from text file which is placed in certain location and i have to load it to oracle database.
so I can't use SQL * loader.
Please help me something with this...
Thanks in advance.

1. Create a dictionary object in Oracle and assign it to the folder where your file resides
2. Write a little procedure which opens the file in the newly created directory object using ULT_FILE and inside the FOR LOOP and do INSERTs to table you want
3. Create a shell script and call that procedure
You can use the post in my Blog for such issues

Pool data from text file and insert into database

Can anyone tell me how to pool data from a text file and insert into database?
let's say my text file is in this format
123456 Peter 22
234567 Nicholas 24
345678 Jane 20
Then I need to insert the all the value for this three column into a table which has the three column name ID, Name, Age
Anyone knows? I need to do this urgently...Thank in advanced

1. Use BufferedReader and read the file line by line.
2. Loop thru the file and do the following steps with in this loop.
3. Use StringTokenizer to seperate each line into three values (columns).
4. Now create a insert statement with these values and add the statement to the batch (using addBatch() method of PreparedStatement or Statement).
5. Finally (after exiting the loop), execute these batch of statements (using ps.executeBatch()).

Show us how you've read the data and what you've tried to do to parse it. Once you've got the last rows, you can loop over them using Spreadsheet String to Array (after cleaning up a few messy spaces).
Jim,

Read data from a text file, one line at a time.

I need to read data from a text file, and display each line in a String Indicator on Front Panel. It displays each line, but I get Error 4, End Of Line, unless I enter an extra line of data in the file that I don't need. I tried Read From Text File.vi, made by Nat Instr, and it gave the same error.

The Read from Text File.vi reads data from a text file line by line until the user stops the VI manually with the Stop button on the front panel, or until an error (such as "Error 4, End of file") occurs. If an error occurs, the Simple Error Handler.vi pops up a dialog that tells you which error occurred.
The Read from Text File.vi uses a while loop, but if you knew how many lines you wanted to read, you could replace the while loop with a for loop set to read that many lines from the file.
If you need something more dynamic because the number of lines in your files vary, then you could change the code of the Read from Text File.vi to the expect "Error 4, End of file" and handle it appropriately. This would require unbundling the error cluster that comes fro
m the Read File function with the Unbundle By Name function, so that you can expose the individual error "status" and error "code" values stored in the cluster. If the value of the error "code" is 4, then you can change the error "status" from true to false, and you can rebundle the cluster with the Bundle by Name function. Setting the error "status" to false instructs the Simple Error Handler to ignore the error. Otherwise, pass the original error cluster to the Simple Error Handler.vi, so that you can see what the error is.
Of course, if you're not interested in what the errors are, you could just remove the Simple Error Handler.vi, but then you wouldn't see any error messages.

Reading from a text file and displaying the contents with in a frame

Hi All,
I am trying to read some data from a text file and display it on a AWT Frame. The contents of the text file are as follows:
pcode1,pname1,price1,sname1,
pcode2,pname2,price2,sname1,
I am writing a method to read the contents from a text file and store them into a string by using FileInputStream and InputStreamReader.
Now I am dividing the string(which has the contents of the text file) into tokens using the StringTokenizer class. The method is as show below
void ReadTextFile()
                    FileInputStream fis=new FileInputStream(new File("nieman.txt"));
                     InputStreamReader isr=new InputStreamReader(fis);
                     char[] buf=new char[1024];
                     isr.read(buf,0,1024);
                     fstr=new String(buf);
                     String Tokenizer st=new StringTokenizer(fstr,",");
                     while(st.hasMoreTokens())
                                      pcode1=st.nextToken();
                           pname1=st.nextToken();
          price1=st.nextToken();
                          sname1=st.nextToken();
     } //close of while loop
                } //close of methodHere goes my problem: I am unable to display the values of pcode1,pname1,price1,sname1 when I am trying to access them from outside the ReadTextFile method as they are storing "null" values . I want to create a persistent string variable so that I can access the contents of the string variable from anywhere with in the java file. Please provide your comments for this problem as early as possible.
Thanks in advance.

If pcode1,pname1,price1,sname1 are global variables, which I assume they are, then simply put the word static in front of them. That way, any class in your file can access those values by simply using this notation:
MyClassName.pcode1;
MyClassName.pname1;
MyClassName.price1;
MyClassName.sname1

Plotting from a text file like a media player example.jpg ‏61 KB

HI Martin,
i am not realy sure what you want!?!?
i think you want to display only a part of the values you read from XYZ
so what you can do:
write all the values in an array.
the size of the array is the max. value of the slide bar
now you can select a part of the array (e.g. values from 100 to 200) and display this with a graph
the other option is to use the history function of the graphes

Error while loading data from a text file to a datastore

Hi all,
i am a starter in ODI. I am trying to load data from a text file into a datastore. I have put the file on a unix server whose location is defined in the topology manager. when i am trying to "view data" it is giving me error file does not exist at <location where i have put the file>. Please help me

Hi,
1. If your files are on a remote File System, you will need to copy one of your files to the machine ODI Designer is running on to allow ODI to retrieve the metadata information of the file.
2. In Topology create a Physical Schema, the directory you enter for Data and Work Schema should point at this local file.
3. Then define the File Datastore in ODI Designer. Enter a name, browse and select the file and fill in each filed of the Files tab.
* If its a Fixed file, click on the grid icon on the Columns tab to enter the columns and have Automatic Adjustment checked.
* If its a Delimited file, use the Reverse button on the Columns tab to reverse the columns.
* Right click on the File Datastore select View Data, if you can view data, that means the File Datastore has been defined correctly.
* If not, check each tab of the File Datastore to make sure everything is defined correctly and retry.
4. Once View Data is successful, you now change the directories (Data and Work Schema in Topology) to point at the remote File System. These directories must be accessible to the ODI Agent that will be used to run the transformations. The directory can be an absolute path (m:/public/data/files) or relative to the ODI Agent startup directory (../demo/files). It is strongly advised to use a UNC (independent from the execution location) for the path. When running the transformations with "no agent", the directory is relative to the directory where Oracle Data Integrator has been installed.
You need to have a agent process running at the system where your source file resides .
Then while running the odi interface choose that agent .
Thanks,
Sutirtha
