Parsing an EDI file and populating the data into database table

Hi ,
Please help me in parsing an edi file and getting the required columns.
we get an EDI file from a bank. I need to parse that file and populate the db table with the required columns.
the file is '*' delimited and every line ends with '\'.
The record starts with 'ST*' and ends with 'SE*'.
sample edi file is
ISA*00*          *00*          *ZZ*043000096820   *ZZ*2156833510     *131202*0710*U*00401*000001204*0*P*>\ ignore first 2 lines

Below is the procedure I am trying to use for parsing that file. but the logic is not working. can you please help me in doing this. its very urgent requirement.

I would not use regular expressions for parsing as it is CPU intensive - and standard string processing suffices.
I would break the EDI up into lines. I would tokenise each line. I then have 2d array that can be referenced to find a specific field. E.g. line x and token y is field abc.
Basic approach:

How can i open a DOC or TXT file and insert the data into table?

How can i open a DOC or TXT file and insert the data into table?
I have a doc file . the doc include some columns and some rows.(for example 'ID,Name,Date,...').
I'd like open DOC file and I'd like insert them into the table with same columns.
Thanks.

Use the SQL*Loader utility or the UTL_FILE package.

Is it possible to have 2 different output config XML files and index the data into 2 endeca apps using the same indexing component ProductCatalogSimpleIndexingAdmin

Hi ,
We have a catalog that defines 2 types of products (they have too many different properties), so wanted to keep them on two different MDEX engines and serve the applications requests. Here DB catalog and front end ATG application is same for both the MDEX instances.
Is it possible to have 2 different output config XML files and index the data into 2 endeca apps using the same indexing component ProductCatalogSimpleIndexingAdmin?
Thanks
Dev

Hi, also have had some problem some monthes ago - I created separete component ProductCatalogSimpleIndexingAdminSecond. After that one of my colleage gave me some advice:
The creating separate component like ProductCatalogSimpleIndexingAdmin for the second IOC is possible way for resolving your situation. But I afraid that this way will be required creating mane duplicates for already existed components.
In my opinion the better way is the following:
starting from AssemblerApplicationConfiguration and ApplicationConfiguration component. It contains details for connecting between ATG and Endeca. Of course you should configure different components for different Endeca Apps.
After that:
Find all components that uses AssemblerApplicationConfiguration and ApplicationConfiguration. Customize these components for using one or another *Configuration component depending on what index works. (many variants released it: the most simple global custom component with flag.)
Then customize the existed ProductCatalogSimpleIndexingAdmin. Using one or another IOC and setting the flag in global custom component when index started. You can add some methods into your custom ProductCatalogSimpleIndexingAdmin like:
Execute baseline index for both IOC (one by one)
Execute baseline for IOC 1
Execute baseline for IOC 2.
Note: you should be afraid about incremental (partial) index in this configuration. But resolving conflicts in incremental index should be done after full implementation these changes.

How to maintain the data into database table

Hi,
experts,
how to maintain the data into database table

There are several ways to maintain data in the database
1. Use table maintanance generator . You can create this using SE11 and data can be edited through SM30.
2. Loginto SE11 with the specified table and check the ATTRIBUTES tab. There you can set some parameters for maintaining the database. When you set Maintain database, you edit the data thorugh SE11 it self
3. Through Se16 as well.
4. A small abap program can do the above task as well.
Thanks,
Raj

(Urgent help needed) how to read txt file and store the data into 2D-array?

Hi, I have a GUI which allow to choose file from the file chooser, and when "Read file" button is pressed, I want to show the array data into the textarea.
The sample data is like this followed:
-0.0007     -0.0061     0.0006
-0.0002     0.0203     0.0066
0     0.2317     0.008
0.0017     0.5957     0.0008
0.0024     1.071     0.0029
0.0439     1.4873     -0.0003
I want my program to scan through and store these data into 2D array.
However for some reason, my source code issues errors, and I don't know what's wrong with it, seems to have a problem in StringTokenizer though. Can anybody help me?
Thanks in advance.

1) Next time use the CODE tags. this is way too much unreadable crap.
2) The problem is your String[][] data.... the only place I see you do anything approching initializing it is
data = new String[numLines][];I think you want to do this..
data = new String[numLines][3];anyway that's why it's blowing up on the line
data[row][col]=st.nextToken();

Want to Read the a txt file and put the data into the table colums.

I have a text file in which data is piped separated and I want to put the data in the table column.
Eg.
Text File Column
First_name|Last_name|address|phone_number
Database table:
first_name ,last_name,address,phone_number
It's very urgent.
Thanks For your help in advance.

Use sqlldr or external file.
See http://download.oracle.com/docs/cd/E11882_01/server.112/e10701/part_ldr.htm#i436326 for SQL Loader.
See http://download.oracle.com/docs/cd/E11882_01/server.112/e10595/tables013.htm#ADMIN11705 for External table.

Stage tab delimited CSV file and load the data into a different table

Hi,
I pretty new to writing PL/SQL packages.
We are using Application express for our development. We get CSV files which is stored as a BLOB content in a table. I need to write a trigger that would get executed once the user the uploads the file and parse thru the Blob content and upload or stage the data in a different table.
I would like to see if there is any tutorial or article that could explain the above process with the example or sample code to do the same. Any help in this regard will be highly appreciated.

Hi,
This is slightly unusual but at the same time easy to solve. You can read through a blob using the dbms_lob package, which is one of the Oracle supplied packages. This is presumably the bit you are missing, as once you know how you read a lob the rest is programming 101.
Alternatively, you could write the lob out to a file on the server using another built in package called utl_file. This file can be parsed using an appropriately defined external table. External tables are the easiest way of reading data from flat files, including csv.
I say unusual because why are you loading a csv file into a blob? A clob is almost understandable but if you can load into a column in a table why not skip this bit and just load the data as it comes in straight into the right table?
All of what I have described is documented functionality, assuming you are on 9i or greater. But you didn't provide a version so I can't provide a link to the documentation ;)

How to read the contents of a text file and populate the data in a table ?

Hello All,
Can anyone advise on how to acheieve the above ? I am trying to read in a text file (CSV) and have the contents populated to the respective UI elements in a table. Any help is greatly appreciated.
from
Kwok Wei

Hi,
Let us consider you have list of names(Seperated by delimeter) in a text file and you want to display in a table.
1. Create Context Node "Names" and context attribute "Name"
2. Create Table and bind to the above context.
3.Write the following code in the "Init method.
try{
FileReader f =new FileReader("");
BufferedReader r=new BufferedReader(f);
String names=r.readLine();
Vector Names=new Vector();
// Use Tokenizer and store all the names i a vector//
for(int i=0;i<Names.size();i++){
IPrivate<<VieName>>.INameElement ele=wdContext.createNameElement();
ele.set<<Name>>( Names.get(i).toString());
wdContext.NodeName().addElement(ele);

Read the file and write the data into string or int

Ok, here's another rookie question.
I got to read the line from the file and store it in the memory as string or integer.
I wrote this code:
File inputFile = new File("c:/xxx.yyy");
String outputString = new String();
FileReader c1 = new FileReader(inputFile);
StringWriter d1 = new StringWriter(outputString);
int data;
         while((data = c1.read()) != -1)
             d1.write(data);
             System.out.println(data);
         c1.close();
         d1.close();This is how I see it, but it cannot be even compiled because there is no such thing as StringWriter(String) wich I find completely irrational. So tell me, am I retarded or what? No, but seriosly, please help the newbie to understand these streams, am I supposed to use some kind of buffer? Any help appreciated.

A String is an immutable. You cannot update a String.
A new String() is basically the same as an empty String ""
An empty StringWriter can be created with new StringWriter().
If you use a BufferedReader you can call readLine().
BufferedReader in = new BufferedReader(new FileReader(filename));
String line;
while((line = in.readLine()) != null) {
System.out.println(line);
}

What I wanna do is to read all the data above and buffer them in a queue for each user( there are only 10 users in total).
I already created a class called Class packet:
public class packet {
    private int timestamp;
    private int user_id;
    private int packet_id;
    private int packet_seqno;
    private int packet_size;
    /** Creates a new instance of packet */
    public packet(int timestamp,int user_id, int packet_id,int packet_seqno, int packet_size)
        this.timestamp = timestamp;
        this.user_id=user_id;
        this.packet_id=packet_id;
        this.packet_seqno=packet_seqno;
        this.packet_size=packet_size;
}then I wanna to create another Class called Class user which I can create a queue for each user (10 users in total) to store type packet information. the queue for each user will be in the order by timestamp.
any idea and sample code will be appreciated.

Doesn't sound too hard to me. Your class User (the convention says to capitalize class names) will have an ArrayList or Vector in it to represent the queue, and a method to store a Packet object into the List. An array or ArrayList or Vector will hold the 10 user objects. You will find the right user object from packet.user_id and call the method.
Please try to write some code yourself. You won't learn anything from having someone else write it for you. Look at sample code using ArrayList and Vector, there's plenty out there. Post in the forum again if your code turns out not to behave.

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
